shareholders of MuniHoldings Pennsylvania Insured Fund and special meetings of
the shareholders of each of MuniYield Pennsylvania Fund and MuniVest
Pennsylvania Insured Fund (the "Meetings") will be held on December 15, 1999

shares held by the shareholder submitting the proxy.

     the funds; and

  For the shareholders of MuniHoldings Pennsylvania Insured Fund only:

  2. To elect a Board of Trustees for the fund; and

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

     The  Securities  and  Exchange  Commission has  not  approved  or
         disapproved these securities or  passed upon the adequacy
             of  this  Proxy  Statement  and  Prospectus.  Any
                 representation  to  the   contrary  is  a
                     criminal offense.
                               ----------------

  This Proxy Statement and Prospectus serves as a prospectus of MuniYield
Pennsylvania in connection with the issuance of MuniYield Pennsylvania Common
Shares and the newly-created series of MuniYield Pennsylvania Series B AMPS in
the Reorganization.

  The Proxy Statement and Prospectus sets forth information about MuniYield
Pennsylvania, MuniVest Pennsylvania and MuniHoldings Pennsylvania that
shareholders of the Funds should know before considering the Reorganization
and should be retained for future reference. Each of the Funds has authorized
the solicitation of proxies in connection with the Reorganization solely on
the basis of this Proxy Statement and Prospectus and the accompanying
documents.

  The address of the principal executive offices of MuniYield Pennsylvania,
MuniVest Pennsylvania and MuniHoldings Pennsylvania is 800 Scudders Mill Road,
Plainsboro, New Jersey 08536, and the telephone number is (609) 282-2800.

  The date of this Proxy Statement and Prospectus is November 10, 1999.



  The common shares of beneficial interest ("Common Shares") of MuniYield
Pennsylvania and MuniVest Pennsylvania are listed on the New York Stock
Exchange (the "NYSE") under the symbols "MPA" (MuniYield Pennsylvania) and
"MVP" (MuniVest Pennsylvania). The Common Shares of MuniHoldings Pennsylvania
are listed on the American Stock Exchange ("AMEX") under the symbol "MPI."
Subsequent to the Reorganization, MuniYield Pennsylvania Common Shares will
continue to be listed on the NYSE under the symbol "MPA." Reports, proxy
materials and other information in the case of MuniYield Pennsylvania and
MuniVest Pennsylvania may be inspected at the offices of the NYSE, 20 Broad
Street, New York, New York 10005 or at the AMEX, 980 Washingtonian Boulevard,
Gaithersburg, Maryland 20878 in the case of MuniHoldings Pennsylvania.

  The Agreement and Plan of Reorganization that you are being asked to
consider involves a transaction that will be referred to in this Proxy
Statement and Prospectus as the Reorganization. The Reorganization involves
the combination of three funds into one fund. The three funds are:

    MuniYield Pennsylvania Fund ("MuniYield Pennsylvania"), which will be the
  surviving fund,

    MuniVest Pennsylvania Insured Fund ("MuniVest Pennsylvania") and

    MuniHoldings Pennsylvania Insured Fund ("MuniHoldings Pennsylvania").

  MuniVest Pennsylvania and MuniHoldings Pennsylvania are sometimes referred
to herein collectively as the "Acquired Funds" and, together with MuniYield
Pennsylvania, as the "Funds."

  In the Reorganization, MuniYield Pennsylvania will (i) acquire substantially
all of the assets and assume substantially all of the liabilities of each of
the Acquired Funds solely in exchange for its common shares of beneficial
interest, par value $.10 per share ("MuniYield Pennsylvania Common Shares"),
and shares of a newly-created series of its auction market preferred shares to
be designated Series B ("MuniYield Pennsylvania Series B AMPS"), with a par
value of $.05 per share and a liquidation preference of $25,000 per share and
(ii) designate the currently outstanding series of AMPS of MuniYield
Pennsylvania as Series A AMPS. The Acquired Funds will distribute the
MuniYield Pennsylvania Common Shares and MuniYield Pennsylvania Series B AMPS
received in the Reorganization to their respective shareholders and will then
liquidate and terminate their registration under the Investment Company Act of
1940 (the "Investment Company Act"). MuniYield Pennsylvania will continue to
operate as a registered closed-end investment company with the investment
objective and policies described in this Proxy Statement and Prospectus. As
part of the Reorganization, the Fund will amend its investment policies to
provide that the Fund, under normal circumstances, will invest at least 80% of
its assets in municipal obligations with remaining maturities of one year or
more that are covered by insurance guaranteeing the timely payment of
principal at maturity and interest, as well as change the Fund's name to
"MuniYield Pennsylvania Insured Fund."

  In the Reorganization, MuniYield Pennsylvania will issue Common Shares and
auction market preferred shares ("AMPS") to each of the Acquired Funds based
on the value of the assets transferred to MuniYield Pennsylvania by that
Acquired Fund. These shares will then be distributed by each Acquired Fund to
its shareholders based on the value of the shares held by each shareholder
just prior to the Reorganization. A holder of Common Shares of an Acquired
Fund will receive MuniYield Pennsylvania Common Shares and a holder of AMPS of
an Acquired Fund will receive MuniYield Pennsylvania Series B AMPS.

                                 INTRODUCTION

  This Proxy Statement and Prospectus is furnished in connection with the
solicitation of proxies on behalf of the Boards of Trustees of MuniYield
Pennsylvania, MuniVest Pennsylvania and MuniHoldings Pennsylvania for use at
the Meetings to be held at the offices of Merrill Lynch Asset Management, L.P.
("MLAM"), 800 Scudders Mill Road, Plainsboro, New Jersey on December 15, 1999,
at the time specified for each Fund in Exhibit I to this Proxy Statement and
Prospectus. The mailing address for each of the Funds is P.O. Box 9011,
Princeton, New Jersey 08543-9011. The approximate mailing date of this Proxy
Statement and Prospectus is November 12, 1999.

  Any person giving a proxy may revoke it at any time prior to its exercise by
executing a superseding proxy, by giving written notice of the revocation to
the Secretary of MuniYield Pennsylvania, MuniVest Pennsylvania or MuniHoldings
Pennsylvania, as applicable, at the address indicated above or by voting in
person at the appropriate Meeting. All properly executed proxies received
prior to the Meetings will be voted at the Meetings in accordance with the
instructions marked thereon or otherwise as provided therein. Unless
instructions to the contrary are marked, (a) all proxies will be voted "FOR"
Item 1 to approve the Agreement and Plan of Reorganization among MuniYield
Pennsylvania, MuniVest Pennsylvania and MuniHoldings Pennsylvania (the
"Agreement and Plan of Reorganization"); and (b) for the shareholders of
MuniHoldings Pennsylvania only, all proxies submitted by MuniHoldings
Pennsylvania shareholders will be voted "FOR" Item 2 to elect a Board of
Trustees of MuniHoldings Pennsylvania to serve for the ensuing year; and "FOR"
Item 3 to ratify the selection of Deloitte & Touche LLP as the independent
auditors of MuniHoldings Pennsylvania for its current fiscal year.

  With respect to Item 1, assuming a quorum is present at the Meetings,
approval of the Agreement and Plan of Reorganization will require the
affirmative vote of shareholders representing (i) a majority of the
outstanding Common Shares of MuniYield Pennsylvania and MuniYield Pennsylvania
AMPS, voting together as a single class, and a majority of the outstanding
shares of MuniYield Pennsylvania AMPS, voting separately as a class, (ii) a
majority of the outstanding Common Shares of MuniVest Pennsylvania and
MuniVest Pennsylvania AMPS, voting together as a single class, and a majority
of the outstanding shares of MuniVest Pennsylvania AMPS, voting separately as
a class, and (iii) a majority of the outstanding Common Shares of MuniHoldings
Pennsylvania and MuniHoldings Pennsylvania AMPS, Series A, voting together as
a single class, and a majority of the outstanding shares of MuniHoldings
Pennsylvania AMPS, Series A, voting separately as a class. Because of the
requirement that the Agreement and Plan of Reorganization be approved by
shareholders of all three Funds, the Reorganization will not take place if
shareholders of any one Fund do not approve the Agreement and Plan of
Reorganization.

  With respect to Item 2, holders of MuniHoldings Pennsylvania AMPS, Series A,
are entitled to elect two Trustees of MuniHoldings Pennsylvania, and holders
of MuniHoldings Pennsylvania Common Shares and AMPS, voting together as a
single class, are entitled to elect the remaining Trustees of MuniHoldings
Pennsylvania. Assuming a quorum is present at the annual meeting of
MuniHoldings Pennsylvania, election of the two Trustees of MuniHoldings
Pennsylvania to be elected by the holders of AMPS, voting separately as a
class, will require the affirmative vote of a majority of the votes cast by
the holders of MuniHoldings Pennsylvania AMPS, Series A, represented at the
annual meeting and entitled to vote; and election of the remaining Trustees of
MuniHoldings Pennsylvania will require the affirmative vote of a majority of
the votes cast by the holders of Common Shares and the holders of AMPS,
represented at the annual meeting and entitled to vote, voting together as a
single class.

  With respect to Item 3, assuming a quorum is present at the annual meeting
of MuniHoldings Pennsylvania, approval of the ratification of the selection of
independent auditors of MuniHoldings Pennsylvania will require the affirmative
vote of a majority of the MuniHoldings Pennsylvania Common Shares and AMPS
represented at the annual meeting in person or by proxy, and entitled to vote,
voting together as a single class.

  The Board of Trustees of each of the Funds has fixed the close of business
on October 20, 1999 as the record date (the "Record Date") for the
determination of shareholders entitled to notice of, and to vote at, the

                                       5


Meetings or any adjournment thereof. Shareholders on the Record Date will be
entitled to one vote for each share held, with no shares having cumulative
voting rights. At the Record Date, each Fund had outstanding the number of
Common Shares and AMPS indicated in Exhibit I. To the knowledge of the
management of each of the Funds, no person owned beneficially more than 5% of
the respective outstanding shares of either class of capital stock of any Fund
at the Record Date.

  The Boards of Trustees of the Funds know of no business other than that
discussed in Items 1, 2 and 3 above that will be presented for consideration
at the Meetings. 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.

  The class of shareholders solicited and entitled to vote on each proposal is
outlined in the chart below:

                          ITEM 1. THE REORGANIZATION

SUMMARY

  The following is a summary of certain information contained elsewhere in
this Proxy Statement and Prospectus and is qualified in its entirety by
reference to the more complete information contained in this Proxy Statement
and Prospectus and in the Agreement and Plan of Reorganization attached hereto
as Exhibit II.

  In this Proxy Statement and Prospectus, the term "Reorganization" refers
collectively to (i) the acquisition of substantially all of the assets and the
assumption of substantially all of the liabilities of MuniVest Pennsylvania by
MuniYield Pennsylvania and the subsequent distribution of MuniYield
Pennsylvania Common Shares and MuniYield Pennsylvania Series B AMPS,
respectively, to the holders of MuniVest Pennsylvania Common Shares and
MuniVest Pennsylvania AMPS; (ii) the acquisition of substantially all of the
assets and the assumption of substantially all of the liabilities of
MuniHoldings Pennsylvania by MuniYield Pennsylvania and the subsequent
distribution of MuniYield Pennsylvania Common Shares and MuniYield
Pennsylvania Series B AMPS, respectively, to the holders of MuniHoldings
Pennsylvania Common Shares and MuniHoldings Pennsylvania AMPS, Series A; (iii)
the designation of the currently outstanding series of AMPS of MuniYield
Pennsylvania as Series A, (iv) the amendment to the investment policies of
MuniYield Pennsylvania to provide that the Fund be subject to the requirement
that under normal circumstances the Fund will invest at least 80% of its total
assets in municipal obligations with remaining maturities of one year or more
that are covered by insurance guaranteeing the timely payment of principal at
maturity and interest, as well as the change in the Fund's name to "MuniYield
Pennsylvania Insured Fund" and (v) the subsequent deregistration and
termination of each of MuniVest Pennsylvania and MuniHoldings Pennsylvania.

                                       6



  At meetings of the Boards of Trustees of each of the Funds, the Board of
Trustees of MuniVest Pennsylvania and MuniHoldings Pennsylvania voted
unanimously to approve the Reorganization and the Board of Trustees of
MuniYield Pennsylvania approved the Reorganization by the affirmative vote of
all of the Trustees present at the meeting, representing more than two-thirds
of the total number of Trustees. Subject to obtaining the necessary approvals
from the shareholders of each of the Funds, the Board of Trustees of each
Acquired Fund also deemed advisable the deregistration of the Fund under the
Investment Company Act of 1940, as amended (the "Investment Company Act") and
its termination under the laws of the Commonwealth of Massachusetts. The
Reorganization requires approval of the shareholders of each of the three
Funds. The Reorganization will not take place if the shareholders of any one
Fund do not approve the Agreement and the Plan of Reorganization.

  Each of the Funds seeks to provide shareholders with current income exempt
from Federal income tax and Pennsylvania personal income taxes. Each of the
Funds seeks to achieve its investment objective by investing primarily in a
portfolio of long-term investment grade Pennsylvania municipal obligations,
the interest on which, in the opinion of bond counsel to the issuer, is exempt
from Federal income tax and Pennsylvania personal income taxes. With the
exception of MuniYield Pennsylvania, at least 80% of each Fund's total assets
will be invested in municipal obligations with remaining maturities of one
year or more that are covered by insurance guaranteeing the timely payment of
principal at maturity and interest. Unlike the other Funds, MuniYield
Pennsylvania is not currently required to invest in municipal obligations that
are covered by insurance; however, after the Reorganization, MuniYield
Pennsylvania will be subject to the same requirement as the Acquired Funds. In
connection with approving the Reorganization, the Board of Trustees of
MuniYield Pennsylvania approved this change in the investment policies of that
Fund to provide that the Fund will invest at least 80% of its assets in
municipal obligations either (i) insured under an insurance policy purchased
by the Fund or (ii) insured under an insurance policy obtained by the issuer
thereof or any other party. The Board of Trustees of MuniYield Pennsylvania
also approved a change in the name of that Fund to "MuniYield Pennsylvania
Insured Fund."

  Investing in insured Municipal Bonds and Pennsylvania Municipal Bonds may
result in a Fund's having a lower yield than a fund that does not invest in
insured bonds. FAM believes, however, that any such decrease in yield would
not be material and would be offset by the lower overall operating expense
ratio of the combined fund after the Reorganization. In addition, because the
portfolio of MuniYield Pennsylvania currently consists of a high percentage of
insured Municipal Bonds and Pennsylvania Municipal Bonds (as of October 21,
1999, approximately 58.5%), it is not anticipated that it will be necessary to
engage in a significant restructuring of the portfolio of MuniYield
Pennsylvania or to dispose of a substantial number of holdings as a result of
the Reorganization.

  Each of the Funds is a non-diversified, leveraged, closed-end management
investment company registered under the Investment Company Act. If the
shareholders of the Funds approve the Reorganization, (i) MuniYield
Pennsylvania Common Shares and MuniYield Pennsylvania Series B AMPS will be
issued to MuniVest Pennsylvania in exchange for the assets of MuniVest
Pennsylvania; (ii) MuniYield Pennsylvania Common Shares and MuniYield
Pennsylvania Series B AMPS will be issued to MuniHoldings Pennsylvania in
exchange for the assets of MuniHoldings Pennsylvania; and (iii) MuniVest
Pennsylvania and MuniHoldings Pennsylvania will distribute these shares to
their respective shareholders as provided in the Agreement and Plan of
Reorganization. After the Reorganization, each of MuniVest Pennsylvania and
MuniHoldings Pennsylvania will terminate its registration under the Investment
Company Act and its organization under Massachusetts law.

  Based upon their evaluation of all relevant information, the Trustees of
each of the Funds have determined that the Reorganization will potentially
benefit the holders of Common Shares of that Fund. Specifically, after the
Reorganization, shareholders of each of the Acquired Funds will remain
invested in a closed-end fund that has an investment objective and policies
substantially similar to the Acquired Fund's investment objective and policies
and that uses substantially the same management personnel. In addition, it is
anticipated that holders of Common Shares of each of the Funds will be subject
to a reduced overall operating expense ratio based on the anticipated pro
forma combined total operating expenses and the total combined assets of the
surviving fund after the Reorganization. The Boards also considered the
relative tax positions of the Funds' portfolios and the effect on MuniYield
Pennsylvania shareholders of the change in investment policy. It is not
anticipated

                                       7


that the Reorganization will directly benefit the holders of shares of AMPS of
any of the Funds; however, the Reorganization will not adversely affect the
holders of shares of AMPS of any of the Funds and the expenses of the
Reorganization will not be borne by the holders of shares of AMPS of any of
the Funds.

  If all of the requisite approvals are obtained, it is anticipated that the
Reorganization will occur as soon as practicable after such approval, provided
that the Funds have obtained prior to that time a favorable private letter
ruling from the Internal Revenue Service (the "IRS") concerning the tax
consequences of the Reorganization as set forth in the Agreement and Plan of
Reorganization or an opinion of counsel to the same effect. Under the
Agreement and Plan of Reorganization, however, the Board of Trustees of any
Fund may cause the Reorganization to be postponed or abandoned in certain
circumstances should such Board determine that it is in the best interests of
the shareholders of that Fund to do so. The Agreement and Plan of
Reorganization may be terminated, and the Reorganization abandoned, whether
before or after approval by the Funds' shareholders, at any time prior to the
Exchange Date (as defined below), (i) by mutual consent of the Boards of
Trustees of all of the Funds or (ii) by the Board of Trustees of any Fund if
any condition to that Fund's obligations has not been fulfilled or waived by
such Fund's Board of Trustees.

(a) No information is presented with respect to AMPS because no Fund's
    operating expenses or expenses of the Reorganization will be borne by the
    holders of AMPS of any of the Funds. Generally, AMPS are sold at a fixed
    liquidation preference of $25,000 per share and investment return is set
    at an auction.
(b) Common Shares purchased in the secondary market may be subject to
    brokerage commissions or other charges.
(c) No sales load will be charged on the issuance of shares in the
    Reorganization. Common Shares are not available for purchase from the
    Funds but may be purchased through a broker-dealer subject to individually
    negotiated commission rates.

(d) The annual operating expenses for pro forma MuniYield Pennsylvania are
    projections for a 12-month period.

(e) Based on net assets of each Fund and pro forma MuniYield Pennsylvania,
    excluding assets attributable to AMPS. If assets attributable to AMPS are
    included, the Investment Advisory Fees would be 0.50% for MuniYield
    Pennsylvania, MuniVest Pennsylvania and pro forma MuniYield Pennsylvania,
    and 0.55% for MuniHoldings Pennsylvania and the Total Annual Expenses
    would be 0.79%, 0.87%, 1.02%, and 0.72%.

An investor would pay the following expenses on a
 $1,000 investment assuming (1) the operating expense
 ratio for each Fund (as a percentage of net assets
 attributable to Common Shares) set forth in the table
 above and (2) a 5% annual return throughout the
 period:
  MuniYield Pennsylvania............................... $12   $37   $64  $141
  MuniVest Pennsylvania................................ $14   $42   $73  $160
  MuniHoldings Pennsylvania............................ $17   $54   $93  $202
  Pro Forma MuniYield Pennsylvania*.................... $11   $35   $61  $134

* Assumes that the Reorganization had taken place on June 30, 1999.

  The foregoing Fee Table is intended to assist investors in understanding the
costs and expenses that a holder of Common Shares of each of the Funds will
bear directly or indirectly as compared to the costs and expenses that would
be borne by such investors taking into account the Reorganization. The Example
set forth above assumes that Common Shares were purchased in the initial
offerings and the reinvestment of all dividends and distributions and uses a
5% annual rate of return as mandated by Securities and Exchange Commission
(the "SEC") regulations. The Example should not be considered a representation
of past or future expenses or annual rates of return. Actual expenses or
annual rates of return may be more or less than those assumed for purposes of
the Example. See "The Reorganization--Potential Benefits to Shareholders of
the Funds as a Result of the Reorganization."

Business of MuniYield
 Pennsylvania..................  MuniYield Pennsylvania was organized as a
                                 business trust under the laws of the
                                 Commonwealth of Massachusetts on August 24,
                                 1992 and commenced operations on October 30,
                                 1992. MuniYield Pennsylvania is a non-
                                 diversified, leveraged, closed-end management
                                 investment company whose investment objective
                                 is to provide shareholders with current
                                 income exempt from Federal income tax and
                                 Pennsylvania personal income taxes. MuniYield
                                 Pennsylvania seeks to achieve its investment
                                 objective by investing primarily in a
                                 portfolio of long-term investment grade
                                 municipal obligations issued by or on behalf
                                 of the Commonwealth of Pennsylvania, the
                                 interest on which, in the opinion of bond
                                 counsel to the issuer, is exempt from Federal
                                 income taxes and Pennsylvania personal income
                                 taxes ("Pennsylvania Municipal Bonds").
                                 Unlike the other Funds, MuniYield
                                 Pennsylvania currently is not required to
                                 invest in municipal obligations that are
                                 covered by insurance. Upon approval of the
                                 Reorganization, however, the combined fund
                                 will be subject to the requirement that under
                                 normal circumstances, at least 80% of its
                                 total assets will be invested in municipal
                                 obligations with remaining maturities of one
                                 year or more that are covered by insurance
                                 guaranteeing the timely payment of principal
                                 at maturity and interest. The Fund intends to
                                 invest primarily in long-term Pennsylvania
                                 Municipal Bonds and other long-term municipal
                                 obligations exempt from Federal income tax
                                 but not Pennsylvania personal income taxes
                                 ("Municipal Bonds") with a maturity of more
                                 than ten years. The weighted average maturity
                                 of the Fund's portfolio was 22.92 years as of

                                 September 30, 1999. The average maturity of
                                 the Fund's

                                       9



                                 portfolio securities, and therefore the
                                 Fund's portfolio as a whole, will vary based
                                 upon the assessment of Fund Asset Management,
                                 L.P. ("FAM"), the Fund's investment adviser,
                                 of economic and market conditions. See
                                 "Comparison of the Funds--Investment

Business of MuniVest
 Pennsylvania..................  MuniVest Pennsylvania was organized as a
                                 business trust under the laws of the
                                 Commonwealth of Massachusetts on May 6, 1993
                                 and commenced operations on July 30, 1993.
                                 MuniVest Pennsylvania is a non-diversified,
                                 leveraged, closed-end management investment
                                 company whose investment objective is to
                                 provide shareholders with current income
                                 exempt from Federal income tax and
                                 Pennsylvania personal income taxes. MuniVest
                                 Pennsylvania seeks to achieve its objective
                                 by investing primarily in a portfolio of
                                 Pennsylvania Municipal Bonds. Under normal
                                 circumstances, at least 80% of MuniVest
                                 Pennsylvania's total assets will be invested
                                 in municipal obligations with remaining
                                 maturities of one year or more that are
                                 covered by insurance guaranteeing the timely
                                 payment of principal at maturity and
                                 interest. The Fund intends to invest
                                 primarily in long-term Pennsylvania Municipal
                                 Bonds and Municipal Bonds with a maturity of
                                 more than ten years. The weighted average
                                 maturity of the Fund's portfolio was 21.63
                                 years as of September 30, 1999. The average
                                 maturity of the Fund's portfolio securities,
                                 and therefore the Fund's portfolio as a
                                 whole, will vary based upon FAM's assessment
                                 of economic and market conditions. See
                                 "Comparison of the Funds--Investment

Business of MuniHoldings
 Pennsylvania..................
                                 MuniHoldings Pennsylvania was organized as a
                                 business trust under the laws of the
                                 Commonwealth of Massachusetts on December 3,
                                 1998 and commenced operations on February 26,
                                 1999. MuniHoldings Pennsylvania is a non-
                                 diversified, leveraged, closed-end management
                                 investment company whose investment objective
                                 is to provide shareholders with current
                                 income exempt from Federal income taxes and
                                 Pennsylvania personal income taxes.
                                 MuniHoldings Pennsylvania seeks to achieve
                                 its investment objective by investing
                                 primarily in a portfolio of Pennsylvania
                                 Municipal Bonds. Under normal circumstances,
                                 at least 80% of MuniHoldings Pennsylvania's
                                 total assets will be invested in municipal
                                 obligations with remaining maturities of one
                                 year or more that are covered by insurance
                                 guaranteeing the timely payment of principal
                                 at maturity and interest. The Fund intends to
                                 invest primarily in

                                      10



                                 long-term Pennsylvania Municipal Bonds and
                                 Municipal Bonds with a maturity of more than
                                 ten years. The weighted average maturity of
                                 the Fund's portfolio was 22.48 years as of
                                 September 30, 1999. The average maturity of
                                 the Fund's portfolio securities, and
                                 therefore the Fund's portfolio as a whole,
                                 will vary based upon FAM's assessment of
                                 economic and market conditions. See
                                 "Comparison of the Funds--Investment
                                 Objectives and Policies."

                                 MuniHoldings Pennsylvania has outstanding
                                 Common Shares and one series of AMPS,
                                 designated Series A ("MuniHoldings
                                 Pennsylvania AMPS"). As of September 30,
                                 1999, MuniHoldings Pennsylvania had net
                                 assets of $48,681,903.

Comparison of the Funds........
                                 Investment Objectives and Policies. The Funds
                                 have substantially similar investment
                                 objectives and policies. All three Funds seek
                                 to provide shareholders (including holders of
                                 AMPS) with current income exempt from Federal
                                 income tax and Pennsylvania personal income
                                 taxes and seek to maintain as much of their
                                 respective portfolios invested in
                                 Pennsylvania Municipal Bonds as possible. The
                                 policies of MuniYield Pennsylvania, however,
                                 differ from the policies of the other Funds
                                 in that MuniYield Pennsylvania currently is
                                 not subject to the requirement that 80% of
                                 its assets be invested in municipal
                                 obligations covered by insurance. After the
                                 Reorganization, however, the combined fund
                                 will be subject to this requirement. See
                                 "Comparison of the Funds--Investment
                                 Objectives and Policies."

                                 Capital Shares. Each Fund has outstanding
                                 both Common Shares and AMPS. The Common
                                 Shares of MuniYield Pennsylvania and MuniVest
                                 Pennsylvania are traded on the NYSE while the
                                 Common Shares of MuniHoldings Pennsylvania
                                 are traded on the AMEX. As of September 30,
                                 1999, (i) the net asset value per share of
                                 MuniYield Pennsylvania Common Shares was

                                 $12.5625; (ii) the net asset value per share
                                 of MuniVest Pennsylvania Common Shares was

                                 $11.6875; and (iii) the net asset value per
                                 share of MuniHoldings Pennsylvania Common
                                 Shares was $12.98 and the market price per
                                 share was $12.00. The AMPS of each of the
                                 Funds have a liquidation preference of
                                 $25,000 per share and are sold principally at
                                 auctions. See "Comparison of the Funds--
                                 Capital Shares."

                                 Auctions generally have been held and will be
                                 held every seven days for each series of AMPS
                                 of each of the Funds unless the applicable
                                 Fund elects, subject to certain limitations,
                                 to have a special dividend period. In
                                 connection with the Reorganization, a holder
                                 of AMPS of MuniHoldings Pennsylvania will
                                 receive MuniYield Pennsylvania AMPS with a
                                 dividend payment date and an auction date
                                 that fall on a day of the week that is
                                 different from the schedule of the AMPS of

                                 average weekly net assets, including assets
                                 acquired from the sale of AMPS, of the
                                 combined fund. For MuniHoldings Pennsylvania,
                                 this represents a fee reduction. See
                                 "Comparison of the Funds--Management of the

                                 Overall Expense Ratio. As of June 30, 1999,
                                 the overall annualized operating expense
                                 ratio for MuniYield Pennsylvania was 1.16%,
                                 based on net assets of approximately $86.3
                                 million excluding AMPS, and 0.79%, based on
                                 net assets of approximately $126.3 million
                                 including AMPS; the overall annualized
                                 operating expense ratio for MuniVest
                                 Pennsylvania was 1.33%, based on net assets
                                 of approximately $52.2 million excluding
                                 AMPS, and 0.87%, based on net assets of
                                 approximately $79.7 million including AMPS;
                                 and the overall annualized operating expense
                                 ratio for MuniHoldings Pennsylvania was
                                 1.71%, based on net assets of approximately
                                 $30.1 million excluding AMPS, and 1.02%,
                                 based on net assets of approximately $50.6
                                 million including AMPS. If the Reorganization
                                 had taken place on June 30, 1999, the overall
                                 operating expense ratio for pro forma
                                 MuniYield Pennsylvania would have been 1.10%,
                                 based on net assets of approximately $168.6
                                 million excluding AMPS, and 0.72%, based on
                                 net assets of approximately $256.6 million
                                 including AMPS.

                                 Purchases and Sales of Common Shares and
                                 AMPS. Purchase and sale procedures for the
                                 Common Shares of each of the Funds are
                                 identical, and investors typically purchase
                                 and sell Common Shares of the Funds through a
                                 registered broker-dealer on the NYSE or the
                                 AMEX, thereby incurring a brokerage
                                 commission set by the broker-dealer.
                                 Alternatively, investors may purchase or sell
                                 Common Shares of the Funds through privately
                                 negotiated transactions with existing
                                 shareholders.

                                 Purchase and sale procedures for the AMPS of
                                 each of the Funds also are identical. Such
                                 AMPS generally are purchased and sold at
                                 separate auctions conducted on a regular
                                 basis by The Bank of New York, as the auction
                                 agent for each Fund's AMPS (the "Auction
                                 Agent"). Unless otherwise permitted by the
                                 Funds, existing and potential holders of AMPS
                                 only may participate in auctions through
                                 their broker-dealers. Broker-dealers submit
                                 the

                                      13


                                 orders of their respective customers who are
                                 existing and potential holders of AMPS to the
                                 Auction Agent. On or prior to each auction
                                 date for the AMPS (the business day next
                                 preceding the first day of each dividend
                                 period), each holder may submit orders to
                                 buy, sell or hold AMPS to its broker-dealer.
                                 Outside of these auctions, shares of AMPS may
                                 be purchased or sold through broker-dealers
                                 for the AMPS in a secondary trading market
                                 maintained by the broker-dealers. However,
                                 there can be no assurance that a secondary
                                 market will develop or if it does develop,
                                 that it will provide holders with a liquid
                                 trading market for the AMPS of any of the
                                 Funds.

                                 Ratings of AMPS. The AMPS of each Fund have
                                 been assigned a rating of AAA from Standard &
                                 Poor's ("S&P") and "aaa" from Moody's
                                 Investors Service, Inc. ("Moody's"). See
                                 "Comparison of the Funds--Rating Agency
                                 Guidelines."

                                 Portfolio Insurance. With the exception of
                                 MuniYield Pennsylvania, each of the other
                                 Funds has a similar policy with respect to
                                 obtaining insurance for portfolio securities.
                                 Under normal circumstances, at least 80% of
                                 each Fund's assets will be invested in
                                 municipal obligations either (i) insured
                                 under an insurance policy purchased by the
                                 Fund or (ii) insured under an insurance
                                 policy obtained by the issuer thereof or any
                                 other party. MuniYield Pennsylvania currently
                                 has no policy with respect to maintaining
                                 insurance on its portfolio; however, after
                                 the Reorganization, MuniYield Pennsylvania
                                 also will, under normal circumstances, have
                                 at least 80% of its assets invested in
                                 municipal obligations either (i) insured
                                 under an insurance policy purchased by the
                                 Fund or (ii) insured under an insurance
                                 policy obtained by the issuer thereof or any
                                 other party. See "Comparison of the Funds--
                                 Investment Objectives and Policies--Portfolio
                                 Insurance."

                                 Ratings of Municipal Obligations. Each of the
                                 Funds will invest only in municipal
                                 obligations that at the time of purchase are
                                 considered investment grade. See "Exhibit
                                 IV--Ratings of Municipal Bonds and Commercial
                                 Paper."

                                 Portfolio Transactions. The portfolio
                                 transactions in which the Funds may engage
                                 are similar, as are the procedures for such
                                 transactions. See "Comparison of the Funds--
                                 Portfolio Transactions."

                                 Dividends and Distributions. The methods of
                                 dividend payment and distributions are
                                 similar for all of the Funds, both with
                                 respect to the Common Shares and the AMPS of
                                 each Fund. See "Comparison of the Funds--
                                 Dividends and Distributions."

                                 Net Asset Value. The net asset value per
                                 Common Share of each Fund is determined after
                                 the close of business on the NYSE (generally,
                                 4:00 p.m., Eastern time) on the last business
                                 day in each week. For purposes of determining
                                 the net asset value of a Common Share of each
                                 Fund, the value of the securities held by the
                                 Fund plus any cash or other assets (including
                                 interest accrued but not yet received) minus
                                 all liabilities (including accrued

                                      14


                                 expenses) and the aggregate liquidation value
                                 of the outstanding AMPS of the Fund is
                                 divided by the total number of Common Shares
                                 of the Fund outstanding at such time.
                                 Expenses, including fees payable to FAM, are
                                 accrued daily. See "Comparison of the Funds--
                                 Net Asset Value."

                                 Voting Rights. The corresponding voting
                                 rights of the holders of Common Shares of
                                 each of the Funds are substantially similar.
                                 Likewise, the corresponding voting rights of
                                 the holders of each Fund's AMPS are
                                 substantially similar. See "Comparison of the
                                 Funds--Capital Shares."

                                 Shareholder Services. An automatic dividend
                                 reinvestment plan is available to holders of
                                 Common Shares of each Fund. The plans are
                                 similar for the three Funds. See "Comparison
                                 of the Funds--Automatic Dividend Reinvestment
                                 Plan." Other shareholder services, including
                                 the provision of annual and semi-annual
                                 reports, are the same for the three Funds.

Tax Considerations.............  The Funds have jointly requested a private
                                 letter ruling from the IRS with respect to
                                 the Reorganization to the effect that, among
                                 other things, no Fund will recognize gain or
                                 loss on the transaction and the shareholders
                                 of the Acquired Funds will not recognize gain
                                 or loss on the exchange of their shares for
                                 MuniYield Pennsylvania Common Shares (except
                                 to the extent that a holder of Common Shares
                                 in an Acquired Fund receives cash
                                 representing an interest in less than a full
                                 share of MuniYield Pennsylvania Common Shares
                                 in the Reorganization) or MuniYield
                                 Pennsylvania AMPS. The consummation of the
                                 Reorganization is subject to the receipt of
                                 such ruling or of an opinion of counsel to
                                 the same effect. The Reorganization will not
                                 affect the status of MuniYield Pennsylvania
                                 as a regulated investment company (a "RIC")
                                 under the Internal Revenue Code of 1986, as
                                 amended (the "Code"). Each of the Acquired
                                 Funds will liquidate pursuant to the
                                 Reorganization. See "Agreement and Plan of
                                 Reorganization--Tax Consequences of the
                                 Reorganization."

                                      15


RISK FACTORS AND SPECIAL CONSIDERATIONS

  Since each of the three Funds invests primarily in a portfolio of
Pennsylvania Municipal Bonds, any risks inherent in such investments apply
equally to all three Funds and will also apply to the combined fund after the
Reorganization. It is expected that the Reorganization itself will not
adversely affect the rights of holders of Common Shares or of any series of
AMPS of any of the Funds or create additional risks.

Pennsylvania Municipal Bonds

  Each of the Funds ordinarily invests at least 65% of its portfolio in
Pennsylvania Municipal Bonds and at least 80% of its portfolio in Pennsylvania
Municipal Bonds and other Municipal Bonds. As a result, each Fund is more
exposed to risks affecting issuers of Pennsylvania Municipal Bonds than is a
municipal bond fund that invests more widely. See "Comparison of the Funds--
Special Considerations Relating to Pennsylvania Municipal Bonds" and Exhibit
III--"Economic and Other Conditions in Pennsylvania."

Interest Rate and Credit Risk

  Each Fund invests in municipal bonds, which are subject to interest rate and
credit risk. Interest rate risk is the risk that prices of municipal bonds
generally increase when interest rates decline and decrease when interest
rates increase. Prices of longer-term securities generally change more in
response to interest rate changes than prices of shorter-term securities.
Credit risk is the risk that the issuer will be unable to pay the interest or
principal when due. The degree of credit risk depends on both the financial
condition of the issuer and the terms of the obligation.

Non-diversification

  Each Fund is registered as a "non-diversified" investment company. This
means that the Fund may invest a greater percentage of its assets in a single
issuer than a diversified investment company. Since a Fund may invest a
relatively high percentage of its assets in a limited number of issuers, the
Fund may be more exposed to the effects of any single economic, political or
regulatory occurrence than a more widely-diversified fund. Even as a non-
diversified fund, each Fund must still meet the diversification requirements
of applicable Federal income tax law.

Rating Categories

  The Funds intend to invest in municipal bonds that are rated investment
grade by S&P, Moody's or Fitch IBCA, Inc. ("Fitch") or are considered by FAM
to be of comparable quality. Obligations rated in the lowest investment grade
category may have certain speculative characteristics.

Private Activity Bonds

  Each Fund may invest all or a portion of its assets in certain tax-exempt
securities classified as "private activity bonds." These bonds may subject
certain investors in a Fund to a Federal alternative minimum tax.

Portfolio Insurance

  Each of the Funds, other than MuniYield Pennsylvania, currently is subject
to certain investment restrictions imposed by guidelines of the insurance
companies that issue portfolio insurance. Following the Reorganization,
MuniYield Pennsylvania also will be subject to these guidelines. The Funds do
not believe these guidelines prevent FAM from managing the Funds' portfolios
in accordance with the Funds' investment objectives and policies.

Leverage

  Currently, the outstanding MuniYield Pennsylvania AMPS represent
approximately 35% of that Fund's capital, the outstanding MuniVest
Pennsylvania AMPS represent approximately 35% of that Fund's capital and the
outstanding MuniHoldings Pennsylvania AMPS represent approximately 40% of that
Fund's capital. After the Reorganization, the outstanding AMPS of the combined
fund will be permitted to represent approximately 40% of the combined fund's
capital.

                                      16


  Use of leverage, through the issuance of AMPS, involves certain risks to
holders of Common Shares of each of the Funds. For example, each Fund's
issuance of AMPS may result in higher volatility of the net asset value of its
Common Shares and potentially more volatility in the market value of its
Common Shares. In addition, changes in the short-term and medium-term dividend
rates on, and the amount of taxable income allocable to, the AMPS will affect
the yield to holders of Common Shares. Under certain circumstances, when a
Fund is required to allocate taxable income to holders of AMPS, the Fund may
be required to make an additional distribution to such holders in an amount
approximately equal to the tax liability resulting from that allocation (an
"Additional Distribution"). Leverage will allow holders of each Fund's Common
Shares to realize a higher current rate of return than if the Fund were not
leveraged as long as the Fund, while accounting for its costs and operating
expenses, is able to realize a higher net return on its investment portfolio
than the then-current dividend rate (and any Additional Distribution) paid on
the AMPS. Similarly, since a pro rata portion of each Fund's net realized
capital gains is generally payable to holders of the Fund's Common Shares, the
use of leverage will increase the amount of such gains distributed to holders
of the Fund's Common Shares. However, short-term, medium-term and long-term
interest rates change from time to time as do their relationships to each
other (i.e., the slope of the yield curve) depending upon such factors as
supply and demand forces, monetary and tax policies and investor expectations.
Changes in any or all of such factors could cause the relationship between
short-term, medium-term and long-term rates to change (i.e., to flatten or to
invert the slope of the yield curve) so that short-term and medium-term rates
may substantially increase relative to the long-term obligations in which each
Fund may be invested. To the extent that the current dividend rate (and any
Additional Distribution) on the AMPS approaches the net return on a Fund's
investment portfolio, the benefit of leverage to holders of Common Shares will
be decreased. If the current dividend rate (and any Additional Distribution)
on the AMPS were to exceed the net return on a Fund's portfolio, holders of
Common Shares would receive a lower rate of return than if the Fund were not
leveraged. Similarly, since both the costs of issuing AMPS and any decline in
the value of a Fund's investments (including investments purchased with the
proceeds from any AMPS offering) will be borne entirely by holders of the
Fund's Common Shares, the effect of leverage in a declining market would
result in a greater decrease in net asset value to holders of Common Shares
than if the Fund were not leveraged. If a Fund is liquidated, holders of that
Fund's AMPS will be entitled to receive liquidating distributions before any
distribution is made to holders of Common Shares of that Fund.

  In an extreme case, a decline in net asset value could affect each Fund's
ability to pay dividends on its Common Shares. Failure to make such dividend
payments could adversely affect the Fund's qualification as a RIC under the
Federal tax laws. See "Comparison of Funds--Tax Rules Applicable to the Funds
and their Shareholders." However, each Fund intends to take all measures
necessary to make dividend payments on its Common Shares. If a Fund's current
investment income is ever insufficient to meet dividend payments on either the
Common Shares or the AMPS, the Fund may have to liquidate certain of its
investments. In addition, each Fund has the authority to redeem its AMPS for
any reason and may redeem all or part of its AMPS under the following
circumstances:

  .  if the Fund anticipates that its leveraged capital structure will result
     in a lower rate of return for any significant amount of time to holders
     of Common Shares than the Fund can obtain if the Common Shares were not
     leveraged,

  .  if the asset coverage for the AMPS declines below 200%, either as a
     result of a decline in the value of the Fund's portfolio investments or
     as a result of the repurchase of Common Shares in tender offers or
     otherwise, or

  .  in order to maintain the asset coverage established by Moody's and S&P
     in rating the AMPS.

Redemption of the AMPS or insufficient investment income to make dividend
payments, may reduce the net asset value of the Common Shares and require the
Fund to liquidate a portion of its investments at a time when it may be
disadvantageous to do so.

Portfolio Management

  The portfolio management strategies of the Funds are the same. In the event
of an increase in short-term or medium-term rates or other change in market
conditions to the point where a Fund's leverage could adversely

                                      17


affect holders of Common Shares as noted above, or in anticipation of such
changes, each Fund may attempt to shorten the average maturity of its
investment portfolio, which would tend to offset the negative impact of
leverage on holders of its Common Shares. Each Fund also may attempt to reduce
the degree to which it is leveraged by redeeming AMPS pursuant to the
provisions of the Fund's Certificate of Designation establishing the rights
and preferences of the AMPS or otherwise purchasing shares of AMPS. Purchases
and sales or redemptions of AMPS, whether on the open market or in negotiated
transactions, are subject to limitations under the Investment Company Act. If
market conditions subsequently change, each Fund may sell previously unissued
shares of AMPS or shares of AMPS that the Fund previously issued but later
repurchased or redeemed.

Inverse Floating Obligations

  A Fund's investments in "inverse floating obligations" or "residual interest
bonds" provide investment leverage because their market value increases or
decreases in response to market changes at a greater rate than fixed rate,
long term tax exempt securities. The market values of such securities are more
volatile than the market values of fixed rate, tax exempt securities.

Options and Futures Transactions

  Each Fund may engage in certain options and futures transactions to reduce
its exposure to interest rate movements. If a Fund incorrectly forecasts
market values, interest rates or other factors, that Fund's performance could
suffer. Each Fund also may suffer a loss if the other party to the transaction
fails to meet its obligations. The Funds are not required to use hedging and
may choose not to do so.

Antitakeover Provisions

  The Declaration of Trust of each of the Funds includes provisions that could
limit the ability of other entities or persons to acquire control of that Fund
or to change the composition of its Board of Trustees. Such provisions could
limit the ability of shareholders to sell their shares at a premium over
prevailing market prices by discouraging a third party from seeking to obtain
control of the Fund.

Ratings Considerations

  The Funds have received ratings of their AMPS of AAA from S&P and "aaa" from
Moody's. In order to maintain these ratings, the Funds are required to
maintain portfolio holdings meeting specified guidelines of such rating
agencies. These guidelines may impose asset coverage requirements that are
more stringent than those imposed by the Investment Company Act.

  As described by Moody's and S&P, a preferred stock rating is an assessment
of the capacity and willingness of an issuer to pay preferred stock
obligations. The ratings of the AMPS are not recommendations to purchase, hold
or sell AMPS, inasmuch as the ratings do not comment as to market price or
suitability for a particular investor, nor do the rating agency guidelines
address the likelihood that a holder of AMPS will be able to sell such shares
in an auction. The ratings are based on current information furnished to
Moody's and S&P by the Funds and FAM and information obtained from other
sources. The ratings may be changed, suspended or withdrawn as a result of
changes in, or the unavailability of, such information. The Common Shares of
the Funds has not been rated by a nationally recognized statistical rating
organization.

  The Board of Trustees of each of the Funds, without shareholder approval,
may amend, alter or repeal certain definitions or restrictions which have been
adopted by the Fund pursuant to the rating agency guidelines, in the event the
Fund receives confirmation from the rating agencies that any such amendment,
alteration or repeal would not impair the ratings then assigned to AMPS.

  As indicated in the tables above, for the periods shown Common Shares of the
Funds generally have traded at prices close to net asset value, with small
premiums or discounts to net asset value of generally less than 15% being
reflected in the market value of the shares from time to time. Although there
is no reason to believe that this pattern should be affected by the
Reorganization, it is not possible to predict whether shares of the surviving
fund will trade at a premium or discount to net asset value following the
Reorganization, or what the extent of any such premium or discount might be.

Investment Objective and Policies

  The structure, organization and investment policies of the Funds are
substantially similar, with the differences among the three Funds set forth
below. Each Fund seeks as a fundamental investment objective current income
exempt from Federal income tax and Pennsylvania personal income taxes. The
investment objective of each Fund is a fundamental policy that may not be
changed without a vote of a majority of the Fund's outstanding voting
securities.

  Each Fund seeks to achieve its investment objective by investing primarily
in a portfolio of Pennsylvania Municipal Bonds. At all times, at least 65% of
each Fund's total assets will be invested in Pennsylvania Municipal Bonds and
at least 80% of each Fund's total assets will be invested in Pennsylvania
Municipal Bonds and in Municipal Bonds, except during interim periods pending
investment of the net proceeds of public offerings of its securities and
during temporary defensive periods. At times, each Fund may seek to hedge its
portfolio through the use of futures and options transactions to reduce
volatility in the net asset value of its Common Shares. Currently, with
respect to MuniVest Pennsylvania and MuniHoldings Pennsylvania, and after the
Reorganization with respect to MuniYield Pennsylvania, under normal
circumstances, at least 80% of each Fund's total assets will be invested in
municipal obligations with remaining maturities of one year or more that are
covered by insurance guaranteeing the timely payment of principal at maturity
and interest. MuniYield Pennsylvania is not currently subject to this
requirement regarding insurance coverage for its portfolio securities but will
adopt this requirement upon approval of the Reorganization by all the Funds.

  Ordinarily, none of the Funds intends to realize significant investment
income subject to Federal income tax and Pennsylvania personal income taxes.
To the extent FAM considers that suitable Pennsylvania Municipal Bonds are not
available for investment, the Funds may purchase Municipal Bonds. Each Fund
may invest all or a portion of its assets in certain tax-exempt securities
classified as "private activity bonds" (in general, bonds that benefit non-
governmental entities) that may subject certain investors in the Fund to a
Federal alternative minimum tax.

  Each Fund also may invest in securities not issued by or on behalf of a
state or territory or by an agency or instrumentality thereof, if the Fund
nevertheless believes such securities pay interest or distributions that are
exempt from Federal income taxation ("Non-Municipal Tax-Exempt Securities").
Non-Municipal Tax-Exempt Securities may include securities issued by other
investment companies that invest in Pennsylvania Municipal Bonds and Municipal
Bonds, to the extent such investments are permitted by the Investment Company
Act. Other Non-Municipal Tax-Exempt Securities could include trust
certificates or other instruments evidencing interests in one or more long-
term Pennsylvania Municipal Bonds or Municipal Bonds. Certain Non-Municipal
Tax-Exempt Securities may be characterized as derivative instruments. For
purposes of a Fund's investment objective and policies, Non-Municipal Tax-
Exempt Securities that pay interest that is exempt from Federal income taxes
and Pennsylvania personal income taxes will be considered "Pennsylvania
Municipal Bonds" and Non-Municipal Tax-Exempt Securities that pay interest
that is exempt from Federal income taxes will be considered "Municipal Bonds".

  The Pennsylvania Municipal Bonds and Municipal Bonds in which the Funds
invest will be rated at the date of purchase in the four highest rating
categories of S&P, Moody's or Fitch or, if unrated, will be considered to be
of comparable quality by FAM. In the case of long-term debt, the investment
grade rating categories are AAA through BBB for S&P and Fitch and Aaa through
Baa for Moody's. In the case of short-term notes, the

                                      25



investment grade rating categories are SP-1 through SP-2 for S&P, MIG-1
through MIG-3 for Moody's and F-1+ through F-3 for Fitch. In the case of tax-
exempt commercial paper, the investment grade rating categories are A-1+
through A-3 for S&P, Prime-1 through Prime-3 for Moody's and F-1+ through F-3
for Fitch. Obligations ranked in the lowest investment grade rating category
(BBB, SP-2 and A-3 for S&P; Baa, MIG-3 and Prime-3 for Moody's; and BBB and F-
3 for Fitch), while considered "investment grade," may have certain
speculative characteristics. There may be sub-categories or gradations
indicating relative standing within the rating categories set forth above. In
assessing the quality of Pennsylvania Municipal Bonds and Municipal Bonds with
respect to the foregoing requirements, FAM takes into account the portfolio
insurance as well as the nature of any letters of credit or similar credit
enhancement to which particular Pennsylvania Municipal Bonds and Municipal
Bonds are entitled and the creditworthiness of the insurance company or
financial institution that provided such insurance or credit enhancements.
Consequently, if Pennsylvania Municipal Bonds or Municipal Bonds are covered
by insurance policies issued by insurers whose claims-paying ability is rated
AAA by S&P or Fitch or Aaa by Moody's, FAM may consider such municipal
obligations to be equivalent to AAA- or Aaa- rated securities, as the case may
be, even though such Pennsylvania Municipal Bonds or Municipal Bonds would
generally be assigned a lower rating if the rating were based primarily upon
the credit characteristics of the issuers without regard to the insurance
feature. The insured Pennsylvania Municipal Bonds and Municipal Bonds must
also comply with the standards applied by the insurance carriers in
determining eligibility for portfolio insurance. See Exhibit IV--"Ratings of
Municipal Bonds and Commercial Paper" and Exhibit V--"Portfolio Insurance."

  Each of the Funds may invest in variable rate demand obligations ("VRDOs")
and VRDOs in the form of participation interests ("Participating VRDOs") in
variable rate tax-exempt obligations held by a financial institution,
typically a commercial bank. The VRDOs in which each Fund may invest are tax-
exempt obligations, in the opinion of counsel to the issuer, that contain a
floating or variable interest rate adjustment formula and a right of demand on
the part of the holder thereof to receive payment of the unpaid principal
balance plus accrued interest on a short notice period not to exceed seven
days. Participating VRDOs provide each Fund with a specified undivided
interest (up to 100%) in the underlying obligation and the right to demand
payment of the unpaid principal balance plus accrued interest on the
Participating VRDOs from the financial institution on a specified number of
days' notice, not to exceed seven days. There is, however, the possibility
that because of default or insolvency, the demand feature of VRDOs or
Participating VRDOs may not be honored. Each Fund has been advised by its
counsel that the Fund should be entitled to treat the income received on
Participating VRDOs as interest from tax-exempt obligations for Federal income
tax purposes.

  The average maturity of each Fund's portfolio securities varies based upon
FAM's assessment of economic and market conditions. The net asset value of the
Common Shares of a closed-end investment company, such as each Fund, which
invests primarily in fixed-income securities, changes as the general levels of
interest rates fluctuate. When interest rates decline, the value of a fixed
income portfolio can be expected to rise. Conversely, when interest rates
rise, the value of a fixed income portfolio can be expected to decline. Prices
of longer-term securities generally fluctuate more in response to interest
rate changes than do short-term or medium-term securities. These changes in
net asset value are likely to be greater in the case of a fund having a
leveraged capital structure, such as that used by the Funds. See "Risk Factors
and Special Considerations--Leverage."

  Each Fund intends to invest primarily in long-term Pennsylvania Municipal
Bonds and Municipal Bonds with a maturity of more than ten years. However,
each Fund may also invest in short-term tax-exempt securities, short-term U.S.
Government securities, repurchase agreements or cash. Such short-term
securities or cash will not exceed 20% of each Fund's total assets except
during interim periods pending investment of the net proceeds from public
offerings of the Fund's securities or in anticipation of the repurchase or
redemption of the Fund's securities and temporary periods when, in the opinion
of FAM, prevailing market or economic conditions warrant.

  Each Fund is classified as non-diversified within the meaning of the
Investment Company Act, which means that the Fund is not limited by such Act
in the proportion of its total assets that it may invest in securities of a
single issuer. However, each Fund's investments are limited so as to qualify
the Fund for the special tax treatment afforded RICs under the Federal tax
laws. To qualify, among other requirements, each Fund limits its investments
so that, at the close of each quarter of the taxable year, (i) not more than
25% of the market value of

                                      26


the Fund's total assets will be invested in the securities (other than U.S.
Government securities) of a single issuer, and (ii) with respect to 50% of the
market value of its total assets, not more than 5% of the market value of its
total assets will be invested in the securities (other than U.S. Government
securities) of a single issuer. A fund that elects to be classified as
"diversified" under the Investment Company Act must satisfy the foregoing 5%
requirement with respect to 75% of its total assets. To the extent that any
Fund assumes large positions in the securities of a small number of issuers,
the Fund's yield may fluctuate to a greater extent than that of a diversified
company as a result of changes in the financial condition or in the market's
assessment of the issuers.

Portfolio Insurance

  Under normal circumstances, at least 80% of the assets of MuniVest
Pennsylvania and MuniHoldings Pennsylvania (referred to in this section as the
"Insured Funds") will be invested in Pennsylvania Municipal Bonds and
Municipal Bonds either (i) insured under an insurance policy purchased by the
Insured Fund, or (ii) insured under an insurance policy obtained by the issuer
thereof or any other party. The Insured Funds will seek to limit their
investments to municipal obligations insured under insurance policies issued
by insurance carriers that have total admitted assets (unaudited) of at least
$75,000,000 and capital and surplus (unaudited) of at least $50,000,000 and
insurance claims-paying ability ratings of AAA from S&P or Fitch, or Aaa from
Moody's. There can be no assurance that insurance from insurance carriers
meeting these criteria will be available. See Exhibit V to this Proxy
Statement and Prospectus for a brief description of insurance claims-paying
ability ratings of S&P, Moody's and Fitch. Currently, it is anticipated that a
majority of the insured Pennsylvania Municipal Bonds and Municipal Bonds in
each Insured Fund's portfolio will be insured by the following insurance
companies which satisfy the foregoing criteria: AMBAC Indemnity Corporation,
Financial Guaranty Insurance Company, Financial Security Assurance and
Municipal Bond Investors Assurance Corporation. Each Insured Fund also may
purchase Pennsylvania Municipal Bonds and Municipal Bonds covered by insurance
issued by any other insurance company that satisfies the foregoing criteria. A
majority of insured Pennsylvania Municipal Bonds and Municipal Bonds held by
each Insured Fund will be insured under policies obtained by parties other
than the Fund.

  MuniYield Pennsylvania is not currently subject to any requirement to invest
in Pennsylvania Municipal Bonds or Municipal Bonds that are insured; however,
after the Reorganization, MuniYield Pennsylvania will be subject to the same
requirement as the Acquired Funds described above. After the Reorganization,
therefore, MuniYield Pennsylvania shareholders will share in the cost of
maintaining such insurance. Currently 58.5% of the portfolio of MuniYield
Pennsylvania is comprised of insured Pennsylvania Municipal Bonds and
Municipal Bonds. It is not anticipated that it will be necessary to engage in
a significant restructuring of the portfolio of MuniYield Pennsylvania or to
dispose of a substantial number of holdings as a result of the Reorganization.

  Each Insured Fund may purchase, but has no obligation to purchase, separate
insurance policies (the "Policies") from insurance companies meeting the
criteria set forth above that guarantee payment of principal and interest on
specified eligible Pennsylvania Municipal Bonds and Municipal Bonds purchased
by the Insured Funds. A Pennsylvania Municipal Bond or Municipal Bond will be
eligible for coverage if it meets certain requirements of the insurance
company set forth in a Policy. In the event interest or principal of an
insured Pennsylvania Municipal Bond or Municipal Bond is not paid when due,
the insurer will be obligated under its Policy to make such payment not later
than 30 days after it has been notified by, and provided with documentation
from, the Fund that such nonpayment has occurred.

  The Policies will be effective only as to insured Pennsylvania Municipal
Bonds and Municipal Bonds beneficially owned by an Insured Fund. In the event
of a sale of any Pennsylvania Municipal Bonds and Municipal Bonds held by an
Insured Fund, the issuer of the relevant Policy will be liable only for those
payments of interest and principal that are then due and owing. The Policies
will not guarantee the market value of an insured Pennsylvania Municipal Bond
or Municipal Bond or the value of the shares of an Insured Fund.

  The insurer will not have the right to withdraw coverage on securities
insured by its Policies and held by an Insured Fund so long as such securities
remain in the Insured Fund's portfolio. In addition, the insurer may not

                                      27


cancel its Policies for any reason except failure to pay premiums when due.
The Board of Trustees of each Insured Fund reserves the right to terminate any
of the Policies if it determines that the benefits to the Insured Fund of
having its portfolio insured under such Policy are not justified by the
expense involved.

  The premiums for the Policies are paid by the Insured Fund and the yield on
its portfolio is reduced thereby. FAM estimates that the cost of the annual
premiums for the Policies of each Insured Fund currently range from
approximately .02 of 1% to .15 of 1% of the principal amount of the
Pennsylvania Municipal Bonds and Municipal Bonds covered by such Policies. The
estimate is based on the expected composition of each Insured Fund's portfolio
of Pennsylvania Municipal Bonds and Municipal Bonds. Additional information
regarding the Policies is set forth in Exhibit V to this Proxy Statement and
Prospectus. In instances in which an Insured Fund purchases Pennsylvania
Municipal Bonds and Municipal Bonds insured under policies obtained by parties
other than the Insured Fund, the Insured Fund does not pay the premiums for
such policies; rather, the cost of such policies may be reflected in the
purchase price of the Pennsylvania Municipal Bonds and Municipal Bonds.

  It is the intention of FAM to retain any insured securities that are in
default or in significant risk of default and to place a value on the
insurance, which ordinarily will be the difference between the market value of
the defaulted security and the market value of similar securities which are
not in default. In certain circumstances, however, FAM may determine that an
alternate value for the insurance, such as the difference between the market
value of the defaulted security and its par value, is more appropriate. FAM's
ability to manage the portfolio of an Insured Fund may be limited to the
extent it holds defaulted securities, which may limit its ability in certain
circumstances to purchase other Pennsylvania Municipal Bonds and Municipal
Bonds. See "Net Asset Value" below for a more complete description of each
Fund's method of valuing defaulted securities and securities that have a
significant risk of default.

  There can be no assurance that insurance with the terms and issued by
insurance carriers meeting the criteria described above will continue to be
available to each Insured Fund. In the event the Board of Trustees of an
Insured Fund determines that such insurance is unavailable or that the cost of
such insurance outweighs the benefits to the Insured Fund, the Insured Fund
may modify the criteria for insurance carriers or the terms of the insurance,
or may discontinue its policy of maintaining insurance for all or any of the
Pennsylvania Municipal Bonds and Municipal Bonds held in the Insured Fund's
portfolio. Although FAM periodically reviews the financial condition of each
insurer, there can be no assurance that the insurers will be able to honor
their obligations under all circumstances.

  The portfolio insurance reduces financial or credit risk (i.e., the
possibility that the owners of the insured Pennsylvania Municipal Bonds or
Municipal Bonds will not receive timely scheduled payments of principal or
interest). However, the insured Pennsylvania Municipal Bonds or Municipal
Bonds are subject to market risk (i.e., fluctuations in market value as a
result of changes in prevailing interest rates).

Description of Pennsylvania Municipal Bonds and Municipal Bonds

  Pennsylvania Municipal Bonds and Municipal Bonds include debt obligations
issued to obtain funds for various public purposes, including construction of
a wide range of public facilities, refunding of outstanding obligations and
obtaining funds for general operating expenses and loans to other public
institutions and facilities. In addition, certain types of private activity
bonds ("PABs") are issued by or on behalf of public authorities to finance
various privately operated facilities, including, among other things,
airports, public ports, mass commuting facilities and multi-family housing
projects as well as facilities for water supply, gas, electricity, sewage or
solid waste disposal. For purposes of this Proxy Statement and Prospectus,
such obligations are considered Municipal Bonds if the interest paid thereon
is exempt from Federal income tax and as Pennsylvania Municipal Bonds if the
interest thereon is exempt from Federal income tax and Pennsylvania personal
income taxes, even though such bonds may be PABs as discussed below.

                                      28


  The two principal classifications of Pennsylvania Municipal Bonds and
Municipal Bonds are "general obligation" bonds and "revenue" bonds, which
latter category includes PABs and, for bonds issued on or before August 15,
1986, industrial development bonds or IDBs. General obligation bonds are
secured by the issuer's pledge of faith, credit and taxing power for the
repayment of principal and the payment of interest. Revenue or special
obligation bonds are generally 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 tax or other specific revenue source such as from
the user of the facility being financed. PABs are in most cases revenue bonds
and do not generally constitute the pledge of the credit or taxing power of
the issuer of such bonds. The repayment of the principal and the payment of
interest on such IDBs depends solely on the ability of the user of the
facility financed by the bonds to meet its financial obligations and the
pledge, if any, of real and personal property so financed as security for such
payment. Pennsylvania Municipal Bonds and Municipal Bonds may also include
"moral obligation" financing, which are normally issued by special purpose
public authorities. In Pennsylvania, moral obligation financing is a financing
arrangement in which designated officials of the Commonwealth of Pennsylvania,
its departments or agencies agree, when necessary, to request the General
Assembly to appropriate funds as may be required to make up any deficiency in
a debt service reserve fund established to assure payment of obligations
issued under the arrangement. The General Assembly is not required to approve
such appropriation requests.

  Each Fund may purchase Pennsylvania Municipal Bonds and Municipal Bonds
classified as PABs. Interest received on certain PABs is treated as an item of
"tax preference" for purposes of the Federal alternative minimum tax and may
impact the overall tax liability of investors in the Fund. There is no
limitation on the percentage of each Fund's assets that may be invested in
Pennsylvania Municipal Bonds and Municipal Bonds the interest on which is
treated as an item of "tax preference" for purposes of the Federal alternative
minimum tax. See "Comparison of the Funds--Tax Rules Applicable to the Funds
and their Shareholders."

  Also included within the general category of Pennsylvania Municipal Bonds
and Municipal Bonds are certificates of participation ("COPs") executed and
delivered for the benefit of government authorities or entities to finance the
acquisition or construction of equipment, land and/or facilities. COPs
represent participations in a lease, an installment purchase contract or a
conditional sales contract (hereinafter collectively referred to as "lease
obligations") relating to such equipment, land or facilities. Although lease
obligations do not constitute general obligations of the issuer for which the
issuer's unlimited taxing power is pledged, a lease obligation frequently is
backed by the issuer's covenant to budget for, appropriate and make the
payments due under the lease obligation. However, certain lease obligations
contain "non-appropriation" clauses which provide that the issuer has no
obligation to make lease or installment purchase payments in future years
unless money is appropriated for such purpose on a yearly basis. Although
"non-appropriation" lease obligations are secured by the lease property,
disposition of the property in the event of foreclosure might prove difficult.

  Federal tax legislation has limited and may continue to limit the types and
volume of bonds the interest on which is excludable from income for Federal
income tax purposes. As a result, this legislation and legislation that may be
enacted in the future may affect the availability of Pennsylvania Municipal
Bonds and Municipal Bonds for investment by the Funds.

Special Considerations Relating to Pennsylvania Municipal Bonds

  Each Fund ordinarily will invest at least 65% of its total assets in
Pennsylvania Municipal Bonds and, therefore, is more susceptible to factors
adversely affecting issuers of Pennsylvania Municipal Bonds than is a
municipal bond fund that is not concentrated in issuers of Pennsylvania
Municipal Bonds to this degree. Pennsylvania's outstanding general obligation
bonds are currently rated Aa3 by Moody's, AA by Fitch and AA by S&P. Because
each Fund's portfolio will comprise investment grade securities, each Fund is
expected to be insulated from the market and credit risks that may exist in
connection with investments in non-investment grade Pennsylvania Municipal
Bonds. There is no assurance that a particular rating will continue for any
given period of time or that any such rating will not be revised downward or
withdrawn entirely if, in the judgment of the agency originally establishing
the rating, circumstances so warrant. The value of Municipal Bonds generally
may

                                      29



be affected by uncertainties in the municipal markets as a result of
legislation or litigation changing the taxation of Municipal Bonds or the
rights of Municipal Bond holders in the event of a bankruptcy. Municipal
bankruptcies are rare, and certain provisions of the U.S. Bankruptcy Code
governing such bankruptcies are unclear. Further, the application of state law
to Municipal Bond issuers could produce varying results among the states or
among Municipal Bond issuers within a state. These uncertainties could have a
significant impact on the prices of the Municipal Bonds or the Pennsylvania
Municipal Bonds in which the Funds invest. FAM does not believe that the
current economic conditions in Pennsylvania or other factors described above
will have a significant adverse effect on any Fund's ability to invest in high
quality Pennsylvania Municipal Bonds. See Exhibit III--"Economic and Other
Conditions in Pennsylvania," and Exhibit IV--"Ratings of Municipal Bonds and
Commercial Paper."

Other Investment Policies

  The Funds have adopted certain other policies as set forth below:

  Borrowings. Each Fund is authorized to borrow amounts of up to 5% of the
value of its total assets at the time of such borrowings; provided, however,
that each Fund is authorized to borrow moneys in amounts of up to 33 1/3% of
the value of its total assets at the time of such borrowings to finance the
repurchase of its own Common Shares pursuant to tender offers or otherwise to
redeem or repurchase preferred shares or for temporary, extraordinary or
emergency purposes. Borrowings by each Fund (commonly known, as with the
issuance of preferred shares, as "leveraging") create an opportunity for
greater total return since the Fund will not be required to sell portfolio
securities to repurchase or redeem shares but, at the same time, increase
exposure to capital risk. In addition, borrowed funds are subject to interest
costs that may offset or exceed the return earned on the borrowed funds.

  When-Issued Securities and Delayed Delivery Transactions. Each Fund may
purchase or sell Pennsylvania Municipal Bonds and Municipal Bonds on a delayed
delivery basis or on a when-issued basis at fixed purchase or sale terms.
These transactions arise when securities are purchased or sold by a Fund with
payment and delivery taking place in the future. The purchase will be recorded
on the date that the Fund enters into the commitment, and the value of the
obligation thereafter will be reflected in the calculation of the Fund's net
asset value. The value of the obligation on the delivery day may be more or
less than its purchase price. A separate account of the Fund will be
established with its custodian consisting of cash, cash equivalents or liquid
securities having a market value at all times at least equal to the amount of
the commitment.

  Indexed and Inverse Floating Obligations. Each Fund may invest in
Pennsylvania Municipal Bonds and Municipal Bonds yielding a return based on a
particular index of value or interest rates. For example, each Fund may invest
in Pennsylvania Municipal Bonds and Municipal Bonds that pay interest based on
an index of Municipal Bond interest rates. The principal amount payable upon
maturity of certain Pennsylvania Municipal Bonds and Municipal Bonds also may
be based on the value of an index. To the extent a Fund invests in these types
of Municipal Bonds, the Fund's return on such Pennsylvania Municipal Bonds and
Municipal Bonds will be subject to risk with respect to the value of the
particular index. Also, a Fund may invest in so-called "inverse floating
obligations" or "residual interest bonds" on which the interest rates
typically vary inversely with a short-term floating rate (which may be reset
periodically by a dutch auction, a remarketing agent, or by reference to a
short-term tax-exempt interest rate index). Each Fund may purchase
synthetically-created inverse floating obligations evidenced by custodial or
trust receipts. Generally, income on inverse floating obligations will
decrease when short-term rates increase, and will increase when short-term
rates decrease. Such securities have the effect of providing a degree of
investment leverage, since they may increase or decrease in value in response
to changes, as an illustration, in market interest rates at a rate that is a
multiple (typically two) of the rate at which fixed-rate, long-term, tax-
exempt securities increase or decrease in response to such changes. As a
result, the market values of such securities generally will be more volatile
than the market values of fixed-rate tax-exempt securities. To seek to limit
the volatility of these securities, a Fund may purchase inverse floating
obligations with shorter-term maturities or limitations on the extent to which
the interest rate may vary. FAM

                                      30


believes that indexed and inverse floating obligations represent a flexible
portfolio management instrument for the Funds that allows FAM to vary the
degree of investment leverage relatively efficiently under different market
conditions.

  Call Rights. Each of the Funds may purchase a Pennsylvania Municipal Bond or
Municipal Bond issuer's rights to call all or a portion of such Pennsylvania
Municipal Bond or Municipal Bond for mandatory tender for purchase (a "Call
Right"). A holder of a Call Right may exercise such right to require a
mandatory tender for the purchase of related Pennsylvania Municipal Bonds or
Municipal Bonds, subject to certain conditions. A Call Right that is not
exercised prior to the maturity of the related Pennsylvania Municipal Bond or
Municipal Bond will expire without value. The economic effect of holding both
the Call Right and the related Pennsylvania Municipal Bond or Municipal Bond
is identical to holding a Pennsylvania Municipal Bond or Municipal Bond as a
non-callable security.

  Repurchase Agreements. The Funds may invest in securities pursuant to
repurchase agreements. Repurchase agreements may be entered into only with a
member bank of the Federal Reserve System or a primary dealer in U.S.
government securities or an affiliate thereof. Under such agreements, the
seller agrees, upon entering into the contract, to repurchase the security at
a mutually agreed-upon time and price, thereby determining the yield during
the term of the agreement. The Funds may not invest in repurchase agreements
maturing in more than seven days if such investments, together with all other
illiquid investments, would exceed 15% of the Fund's net assets. In the event
of default by the seller under a repurchase agreement, the Funds may suffer
time delays and incur costs or possible losses in connection with the
disposition of the underlying securities.

  In general, for Federal income tax purposes, repurchase agreements are
treated as collateralized loans secured by the securities "sold." Therefore,
amounts earned under such agreements will not be considered tax-exempt
interest. In addition, amounts earned under such agreements will not likely be
considered tax-exempt interest for Pennsylvania tax purposes.

Information Regarding Options and Futures Transactions

  Each Fund may hedge all or a portion of its portfolio investments against
fluctuations in interest rates through the use of options and certain
financial futures contracts and options thereon. While each Fund's use of
hedging strategies is intended to reduce the volatility of the net asset value
of the Common Shares, the net asset value of the Common Shares will fluctuate.
There can be no assurance that a Fund's hedging transactions will be
effective. In addition, because of the leveraged nature of the Common Shares,
hedging transactions will result in a larger impact on the net asset value of
the Common Shares than would be the case if the Common Shares were not
leveraged. Furthermore, a Fund may only engage in hedging activities from time
to time and may not necessarily be engaging in hedging activities when
movements in interest rates occur. No Fund has an obligation to enter into
hedging transactions and each may choose not to do so.

  Certain Federal income tax requirements may limit a Fund's ability to engage
in hedging transactions. Gains from transactions in options and futures
contracts distributed to shareholders will be taxable as ordinary income or,
in certain circumstances, as long-term capital gains to shareholders. In
addition, in order to obtain ratings of the AMPS from one or more NRSROs, a
Fund may be required to limit its use of hedging techniques in accordance with
the specified guidelines of such rating organizations. See "Rating Agency
Guidelines" below.

  The following is a description of the options and futures transactions in
which each Fund may engage, limitations on the Fund's use of such transactions
and risks associated with these transactions. The investment policies with
respect to the hedging transactions of a Fund are not fundamental policies and
may be modified by the Board of Trustees of the Fund without the approval of
the Fund's shareholders.

  Writing Covered Call Options.  Each Fund is authorized to write (i.e., sell)
covered call options with respect to Pennsylvania Municipal Bonds and
Municipal Bonds it owns, thereby giving the holder of the option the right to
buy the underlying security covered by the option from the Fund at the stated
exercise price until the

                                      31


option expires. Each Fund writes only covered call options, which means that
so long as the Fund is obligated as the writer of a call option, it will own
the underlying securities subject to the option. The Fund may not write
covered call options on underlying securities in an amount exceeding 15% of
the market value of its total assets.

  Each Fund receives a premium from writing a call option, which increases the
Fund's return on the underlying security in the event the option expires
unexercised or is closed out at a profit. By writing a call, a Fund limits its
opportunity to profit from an increase in the market value of the underlying
security above the exercise price of the option for as long as the Fund's
obligation as a writer continues. Covered call options serve as a partial
hedge against a decline in the price of the underlying security. Each Fund may
engage in closing transactions in order to terminate outstanding options that
it has written.

  Purchase of Options. Each Fund may purchase put options in connection with
its hedging activities. By buying a put, the Fund has a right to sell the
underlying security at the exercise price, thus limiting its risk of loss
through a decline in the market value of the security until the put expires.
The amount of any appreciation in the value of the underlying security will be
partially offset by the amount of the premium paid for the put option and any
related transaction costs. Prior to its expiration, a put option may be sold
in a closing sale transaction; profit or loss from the sale will depend on
whether the amount received is more or less than the premium paid for the put
option plus the related transaction costs. A closing sale transaction cancels
out the Fund's position as the purchaser of an option by means of an
offsetting sale of an identical option prior to the expiration of the option
it has purchased. In certain circumstances, the Fund may purchase call options
on securities held in its portfolio on which it has written call options, or
on securities which it intends to purchase. A Fund will not purchase options
on securities if, as a result of such purchase, the aggregate cost of all
outstanding options on securities held by the Fund would exceed 5% of the
market value of the Fund's total assets.

  Financial Futures Contracts and Options. Each Fund is authorized to purchase
and sell certain financial futures contracts and options thereon solely for
the purposes of hedging its investments in Pennsylvania Municipal Bonds and
Municipal Bonds against declines in value and hedging against increases in the
cost of securities it intends to purchase. A financial futures contract
obligates the seller of a contract to deliver and the purchaser of a contract
to take delivery of the type of financial instrument covered by the contract
or, in the case of index-based financial futures contracts, to make and accept
a cash settlement, at a specific future time for a specified price. A sale of
financial futures contracts may provide a hedge against a decline in the value
of portfolio securities because such depreciation may be offset, in whole or
in part, by an increase in the value of the position in the financial futures
contracts or options. A purchase of financial futures contracts may provide a
hedge against an increase in the cost of securities intended to be purchased,
because such appreciation may be offset, in whole or in part, by an increase
in the value of the position in the financial futures contracts.

  The purchase or sale of a financial futures contract differs from the
purchase or sale of a security in that no price or premium is paid or
received. Instead, an amount of cash or securities acceptable to the broker
equal to approximately 5% of the contract amount must be deposited with the
broker. This amount is known as initial margin. Subsequent payments to and
from the broker, called variation margin, are made on a daily basis as the
price of the financial futures contract fluctuates making the long and short
positions in the financial futures contract more or less valuable.

  Each Fund may purchase and sell financial futures contracts based on The
Bond Buyer Municipal Bond Index, a price-weighted measure of the market value
of 40 large tax-exempt issues, and purchase and sell put and call options on
such financial futures contracts for the purpose of hedging Pennsylvania
Municipal Bonds and Municipal Bonds that the Fund holds or anticipates
purchasing against adverse changes in interest rates. Each Fund also may
purchase and sell financial futures contracts on U.S. Government securities
and purchase and sell put and call options on such financial futures contracts
for such hedging purposes. With respect to U.S. Government securities,
currently there are financial futures contracts based on long-term U.S.
Treasury bonds, U.S. Treasury notes, GNMA Certificates and three-month U.S.
Treasury bills.

                                      32


  Subject to policies adopted by its Board of Trustees, each Fund also may
engage in transactions in other financial futures contracts, such as financial
futures contracts on other municipal bond indices that may become available,
if FAM should determine that there is normally sufficient correlation between
the prices of such financial futures contracts and the Pennsylvania Municipal
Bonds and Municipal Bonds in which the Fund invests to make such hedging
appropriate.

  Over-The-Counter Options. Each Fund may engage in options and futures
transactions on exchanges and in the over-the-counter markets ("OTC options").
In general, exchange-traded contracts are third-party contracts (i.e.,
performance of the parties' obligations is guaranteed by an exchange or
clearing corporation) with standardized strike prices and expiration dates.
OTC option transactions are two-party contracts with price and terms
negotiated by the buyer and seller.

  Restrictions on OTC Options. Each Fund will engage in transactions in OTC
options only with banks or dealers that have capital of at least $50 million
or whose obligations are guaranteed by an entity having capital of at least
$50 million. Certain OTC options and assets used to cover OTC options written
by the Funds are considered to be illiquid. The illiquidity of such options or
assets may prevent a successful sale of such options or assets, result in a
delay of sale, or reduce the amount of proceeds that otherwise might be
realized.

  Risk Factors in Financial Futures Contracts and Options Thereon. Use of
futures transactions involves the risk of imperfect correlation in movements
in the price of financial futures contracts and movements in the price of the
security that is the subject of the hedge. If the price of the financial
futures contract moves more or less than the price of the security that is the
subject of the hedge, a Fund will experience a gain or loss that will not be
completely offset by movements in the price of such security. There is a risk
of imperfect correlation where the securities underlying financial futures
contracts have different maturities, ratings, geographic compositions or other
characteristics different from those of the security being hedged. In
addition, the correlation may be affected by additions to or deletions from
the index that serves as a basis for a financial futures contract. Finally, in
the case of financial futures contracts on U.S. Government securities and
options on such financial futures contracts, the anticipated correlation of
price movements between the U.S. Government securities underlying the futures
or options and Pennsylvania Municipal Bonds and Municipal Bonds may be
adversely affected by economic, political, legislative or other developments
which have a disparate impact on the respective markets for such securities.

  Under regulations of the Commodity Futures Trading Commission, the futures
trading activities described herein will not result in a Fund being deemed a
"commodity pool," as defined under such regulations, provided that the Fund
adheres to certain restrictions. In particular, the Fund may purchase and sell
financial futures contracts and options thereon (i) for bona fide hedging
purposes, without regard to the percentage of the Fund's assets committed to
margin and option premiums, and (ii) for non-hedging purposes, if, immediately
thereafter the sum of the amount of initial margin deposits on the Fund's
existing futures positions and option premiums entered into for non-hedging
purposes do not exceed 5% of the market value of the liquidation value of the
Fund's portfolio, after taking into account unrealized profits and unrealized
losses on any such transactions. Margin deposits may consist of cash or
securities acceptable to the broker and the relevant contract market.

  When a Fund purchases a financial futures contract, or writes a put option
or purchases a call option thereon, it will maintain an amount of cash, cash
equivalents (e.g., commercial paper and daily tender adjustable notes) or
liquid securities in a segregated account with the Fund's custodian, 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 financial futures
contract, thereby ensuring that the use of such financial futures contract is
unleveraged.

  Although certain risks are involved in options and futures transactions, FAM
believes that, because each Fund will engage in options and futures
transactions only for hedging purposes, the options and futures portfolio
strategies of a Fund will not subject the Fund to the risks associated with
speculation in options and futures transactions.

                                      33


  The volume of trading in the exchange markets with respect to Pennsylvania
Municipal Bonds or Municipal Bond options may be limited, and it is impossible
to predict the amount of trading interest that may exist in such options. In
addition, there can be no assurance that viable exchange markets will continue
to be available.

  Each Fund intends to enter into options and futures transactions, on an
exchange or in the over-the-counter market, only if there appears to be a
liquid secondary market for such options or futures. There can be no
assurance, however, that a liquid secondary market will exist at any specific
time. Thus, it may not be possible to close an option or futures transaction.
The inability to close options and futures positions also could have an
adverse impact on a Fund's ability to hedge effectively its portfolio. There
is also the risk of loss by a Fund of margin deposits or collateral in the
event of bankruptcy of a broker with which the Fund has an open position in an
option or financial futures contract.

  The liquidity of a secondary market in a financial futures contract may be
adversely affected by "daily price fluctuation limits" established by
commodity exchanges that limit the amount of fluctuation in a financial
futures contract price during a single trading day. Once the daily limit has
been reached in the contract, no trades may be entered into at a price beyond
the limit, thus preventing the liquidation of open futures positions. Prices
have in the past reached or exceeded the daily limit on a number of
consecutive trading days.

  If it is not possible to close a financial futures position entered into by
a Fund, the Fund would continue to be required to make daily cash payments of
variation margin in the event of adverse price movements. In such a situation,
if the Fund has insufficient cash, it may have to sell portfolio securities to
meet daily variation margin requirements at a time when it may be
disadvantageous to do so.

  The successful use of these transactions also depends on the ability of FAM
to forecast correctly the direction and extent of interest rate movements
within a given time frame. To the extent these rates remain stable during the
period in which a financial futures contract is held by a Fund or move in a
direction opposite to that anticipated, the Fund may realize a loss on the
hedging transaction that is not fully or partially offset by an increase in
the value of portfolio securities. As a result, the Fund's total return for
such period may be less than if it had not engaged in the hedging transaction.
Furthermore, the Fund will only engage in hedging transactions from time to
time and may not necessarily be engaging in hedging transactions when
movements in interest rates occur.

Investment Restrictions

  The Funds have substantially similar investment restrictions. The following
are the current fundamental investment restrictions of MuniYield Pennsylvania.
Following the Reorganization, these restrictions will be the fundamental
investment restrictions for the combined fund. Fundamental investment
restrictions may not be changed without the approval of the holders of a
majority of the outstanding Common Shares and the outstanding AMPS and any
other preferred shares, voting together as a single class, and a majority of
the outstanding AMPS and any other preferred shares, voting separately as a
class. (For this purpose and under the Investment Company Act, for the Common
Shares and AMPS voting together as a single class, "majority" means the lesser
of (i) 67% of the shares of each class of capital shares represented at a
meeting at which more than 50% of the outstanding shares of each class of
capital shares are represented or (ii) more than 50% of the outstanding shares
of each class of capital shares, but for the AMPS voting separately as a
single class, "majority" means more than 50% of the outstanding AMPS.) No Fund
may:

  1. Make investments for the purpose of exercising control or management.

  2. Purchase securities of other investment companies, except in connection
     with a merger, consolidation, acquisition or reorganization, or by
     purchase in the open market of securities of closed-end investment
     companies and only if immediately thereafter not more than 10% of the
     Fund's total assets would be invested in such securities.

  3. Purchase or sell real estate, real estate limited partnerships,
     commodities or commodity contracts; provided that the Fund may invest in
     securities secured by real estate or interests therein or issued by
     companies that invest in real estate or interests therein and the Fund
     may purchase and sell financial futures contracts and options thereon.

                                      34


  4. Issue senior securities other than preferred shares or borrow amounts in
     excess of 5% of its total assets taken at market value; provided,
     however, that the Fund is authorized to borrow moneys in excess of 5% of
     the value of its total assets for the purpose of repurchasing Common
     Shares or redeeming preferred shares.

  5. Underwrite securities of other issuers except insofar as the Fund may be
     deemed an underwriter under the Securities Act of 1933 (the "Securities
     Act") in selling portfolio securities.

  6. Make loans to other persons, except that the Fund may purchase
     Pennsylvania Municipal Bonds, Municipal Bonds and other debt securities
     in accordance with its investment objective, policies and limitations.

  7. Purchase any securities on margin, except that the Fund may obtain such
     short-term credit as may be necessary for the clearance of purchases and
     sales of portfolio securities (the deposit or payment by the Fund of
     initial or variation margin in connection with financial futures
     contracts and options thereon is not considered the purchase of a
     security on margin).

  8. Make short sales of securities or maintain a short position or invest in
     put, call, straddle or spread options, except that the Fund may write,
     purchase and sell options and futures on Pennsylvania Municipal Bonds,
     Municipal Bonds, U.S. Government obligations and related indices or
     otherwise in connection with bona fide hedging activities.

  9. Invest more than 25% of its total assets (taken at market value at the
     time of each investment) in securities of issuers in a single industry;
     provided that, for purposes of this restriction, states, municipalities
     and their political subdivisions are not considered to be part of any
     industry.

  For purposes of restriction (9), the exception for states, municipalities
and their political subdivisions applies only to tax exempt securities issued
by such entities.

  An additional investment restriction adopted by each Fund, which may be
changed by the Trustees, provides that the Fund may not mortgage, pledge,
hypothecate or in any manner transfer, as security for indebtedness, any
securities owned or held by the Fund except as may be necessary in connection
with borrowings mentioned in (4) above or except as may be necessary in
connection with transactions in financial futures contracts and options
thereon.

  If a percentage restriction on the investment or use of assets set forth
above is adhered to at the time a transaction is effected, later changes in
percentages resulting from changing values will not be considered a violation.

  FAM and Merrill Lynch, Pierce, Fenner & Smith Incorporated ("Merrill Lynch")
are owned and controlled by Merrill Lynch & Co., Inc. ("ML & Co."). Because of
the affiliation of Merrill Lynch with FAM, each Fund is prohibited from
engaging in certain transactions involving Merrill Lynch except pursuant to an
exemptive order or otherwise in compliance with the provisions of the
Investment Company Act and the rules and regulations thereunder. Included
among such restricted transactions will be purchases from or sales to Merrill
Lynch of securities in transactions in which it acts as principal. An
exemptive order has been obtained that permits the Funds to effect principal
transactions with Merrill Lynch in high quality, short-term, tax-exempt
securities subject to conditions set forth in such order. The Funds may
consider in the future requesting an order permitting other principal
transactions with Merrill Lynch, but there can be no assurance that such
application will be made and, if made, that such order would be granted.

Rating Agency Guidelines

  Each Fund intends that, so long as its AMPS are outstanding, the composition
of its portfolio will reflect guidelines established by Moody's and S&P in
connection with the Fund's receipt of a rating for such shares on or prior to
their date of original issue of at least "aaa" from Moody's and AAA from S&P.
Moody's and S&P, which are nationally recognized statistical rating
organizations, issue ratings for various securities reflecting the

                                      35


perceived creditworthiness of such securities. The guidelines for rating AMPS
have been developed by Moody's and S&P in connection with issuances of asset-
backed and similar securities, including debt obligations and variable rate
preferred shares, generally on a case-by-case basis through discussions with
the issuers of these securities. The guidelines are designed to ensure that
assets underlying outstanding debt or preferred shares will be varied
sufficiently and will be of sufficient quality and amount to justify
investment-grade ratings. The guidelines do not have the force of law but have
been adopted by each Fund in order to satisfy current requirements necessary
for Moody's and S&P to issue the above-described ratings for AMPS, which
ratings generally are relied upon by institutional investors in purchasing
such securities. The guidelines provide a set of tests for portfolio
composition and asset coverage that supplement (and in some cases are more
restrictive than) the applicable requirements under the Investment Company
Act.

  Each Fund may, but is not required to, adopt any modifications to these
guidelines that hereafter may be established by Moody's or S&P. Failure to
adopt any such modifications, however, may result in a change in the ratings
described above or a withdrawal of the ratings altogether. In addition, any
rating agency providing a rating for the shares of AMPS, at any time, may
change or withdraw any such rating. As set forth in the Certificate of
Designation of each Fund, the Board of Trustees, without shareholder approval,
may modify certain definitions or restrictions that have been adopted by the
Fund pursuant to the rating agency guidelines, provided the Board of Trustees
has obtained written confirmation from Moody's and S&P that any such change
would not impair the ratings then assigned by Moody's and S&P to the AMPS. See
"The Reorganization--Risk Factors and Special Considerations--Ratings
Considerations."

  For so long as any shares of a Fund's AMPS are rated by Moody's or S&P, as
the case may be, a Fund's use of options and financial futures contracts and
options thereon will be subject to certain limitations mandated by the rating
agencies.

Portfolio Composition

  There are small differences in concentration among the categories of issuers
of the Pennsylvania Municipal Bonds and Municipal Bonds held in the portfolios
of the Funds. For MuniYield Pennsylvania, as of August 31, 1999, the highest
concentration of Pennsylvania Municipal Bonds and Municipal Bonds was in
Industrial Revenue/Pollution Control, Education and Hospitals/Healthcare,
accounting for 22%, 15%, and 13% of the Fund's portfolio, respectively; for
MuniVest Pennsylvania, the highest concentration was in Industrial
Revenue/Pollution Control, Hospitals/Healthcare and General Obligation Bonds,
accounting for 24%, 15% and 13%, respectively, of the Fund's portfolio; for
MuniHoldings Pennsylvania, the highest concentration was in General Obligation
Bonds, Education and Industrial Revenue/Pollution Control, accounting for 25%,
18% and 15%, respectively, of the Fund's portfolio.

  Although the investment portfolios of all three Funds must satisfy the same
standards of credit quality, the actual securities owned by each Fund are
different, as a result of which there are certain differences in the
composition of the four investment portfolios. The tables below set forth
rating information for the Pennsylvania Municipal Bonds and Municipal Bonds
held by each Fund, as of a certain date.

                                      36


 MuniYield Pennsylvania

  As of August 31, 1999, approximately 93% of the market value of MuniYield
Pennsylvania's portfolio was invested in long-term municipal obligations and
approximately 7% of the market value of MuniYield Pennsylvania's portfolio was
invested in short-term municipal obligations. The following table sets forth

 MuniVest Pennsylvania

  As of August 31, 1999, approximately 95% of the market value of MuniVest
Pennsylvania's portfolio was invested in long-term municipal obligations and
approximately 5% of the market value of MuniVest Pennsylvania's portfolio was
invested in short-term municipal obligations. The following table sets forth
certain information with respect to the composition of MuniVest Pennsylvania's
long-term municipal obligation investment portfolio as of August 31, 1999.

 MuniHoldings Pennsylvania

  As of August 31, 1999, approximately 91% of the market value of MuniHoldings
Pennsylvania's portfolio was invested in long-term municipal obligations and
approximately 9% of the market value of MuniHoldings Pennsylvania's portfolio
was invested in short-term municipal obligations. The following table sets
forth certain information with respect to the composition of MuniHoldings
Pennsylvania's long-term municipal obligation investment portfolio as of
August 31, 1999.

Portfolio Transactions

  The procedures for engaging in portfolio transactions are the same for each
of the Funds. Subject to policies established by the Board of Trustees of each
Fund, FAM is primarily responsible for the execution of each Fund's portfolio
transactions. In executing such transactions, FAM seeks to obtain the best
results for each Fund, taking into account such factors as price (including
the applicable brokerage commission or dealer spread), size of order,
difficulty of execution and operational facilities of the firm involved and
the firm's risk in positioning a block of securities. While FAM generally
seeks reasonably competitive commission rates, the Funds do not necessarily
pay the lowest commission or spread available.

  None of the Funds has any obligation to deal with any broker or dealer in
the execution of transactions in portfolio securities. Subject to obtaining
the best price and execution, securities firms that provide supplemental
investment research to FAM, including Merrill Lynch, may receive orders for
transactions by a Fund. Information so received will be in addition to, and
not in lieu of, the services required to be performed by FAM under its
investment advisory agreements with the Funds, and the expenses of FAM will
not necessarily be reduced as a result of the receipt of such supplemental
information.

  Each Fund invests in securities that are primarily traded in the over-the-
counter markets, and each Fund normally deals directly with the dealers who
make markets in the securities involved, except in those circumstances where
better prices and execution are available elsewhere. Under the Investment
Company Act, except as permitted by exemptive order, persons affiliated with a
Fund are prohibited from dealing with the Fund as principals in the purchase
and sale of securities. Since transactions in the over-the-counter markets
usually involve transactions with dealers acting as principals for their own
account, the Funds do not deal with affiliated persons, including Merrill
Lynch and its affiliates, in connection with such transactions, except that,
pursuant to an exemptive order obtained by FAM, a Fund may engage in principal
transactions with Merrill Lynch in high quality, short-term, tax-exempt
securities. An affiliated person of a Fund may serve as its broker in over-
the-counter transactions conducted on an agency basis.

  The Funds also may purchase tax-exempt debt instruments in individually
negotiated transactions with the issuers. Because an active trading market may
not exist for such securities, the prices that the Funds may pay for these
securities or receive on their resale may be lower than that for similar
securities with a more liquid market.

                                      38


  The Board of Trustees of each Fund has considered the possibility of
recapturing for the benefit of the Funds brokerage commissions, dealer spreads
and other expenses of possible portfolio transactions, such as underwriting
commissions, by conducting portfolio transactions through affiliated entities,
including Merrill Lynch. For example, brokerage commissions received by
Merrill Lynch could be offset against the investment advisory fees paid by the
Fund to FAM. After considering all factors deemed relevant, the Trustees of
each Fund made a determination not to seek such recapture. The Trustees will
reconsider this matter from time to time.

  Periodic auctions are conducted for the AMPS of each of the Funds by the
Auction Agent for the Funds. The auctions require the participation of one or
more broker-dealers, each of whom enters into an agreement with the Auction
Agent. After each auction, the Auction Agent pays a service charge, from funds
provided by the issuing Fund, to each broker-dealer at the annual rate of
 .25%, calculated on the basis of the purchase price of shares of the relevant
AMPS placed by such broker-dealer at such auction.

Portfolio Turnover

  Generally, no Fund purchases securities for short-term trading profits.
However, any of the Funds may dispose of securities without regard to the time
that they have been held when such action, for defensive or other reasons,
appears advisable to FAM. (The portfolio turnover rate is calculated by
dividing the lesser of purchases or sales of portfolio securities for the
particular fiscal year by the monthly average of the value of the portfolio
securities owned by a Fund during the particular fiscal year. For purposes of
determining this rate, all securities whose maturities at the time of
acquisition are one year or less are excluded.) A high portfolio turnover rate
results in greater transaction costs, which are borne directly by the Fund,
and also has certain tax consequences for shareholders. The portfolio turnover
rate for each of the Funds for the periods indicated is set forth below:

Net Asset Value

  The net asset value per share of Common Shares of each Fund is determined
after the close of business on the NYSE (generally, 4:00 p.m., Eastern time)
on the last business day in each week. For purposes of determining the net
asset value of a share of Common Shares of each Fund, the value of the
securities held by the Fund plus any cash or other assets (including interest
accrued but not yet received) minus all liabilities (including accrued
expenses) and the aggregate liquidation value of the outstanding AMPS is
divided by the total number of Common Shares outstanding at such time.
Expenses, including the fees payable to FAM, are accrued daily.

  The Pennsylvania Municipal Bonds and Municipal Bonds in which each Fund
invests are traded primarily in the over-the-counter markets. In determining
net asset value, each Fund uses the valuations of portfolio securities
furnished by a pricing service approved by its Board of Trustees. The pricing
service typically values portfolio securities at the bid price or the yield
equivalent when quotations are readily available. Pennsylvania

                                      39


Municipal Bonds and Municipal Bonds for which quotations are not readily
available are valued at fair market value on a consistent basis as determined
by the pricing service using a matrix system to determine valuations. The
procedures of the pricing service and its valuations are reviewed by the
officers of each Fund under the general supervision of the Board of Trustees
of the Fund. The Board of Trustees of each Fund has determined in good faith
that the use of a pricing service is a fair method of determining the
valuation of portfolio securities. Positions in futures contracts are valued
at closing prices for such contracts established by the exchange on which they
are traded, or if market quotations are not readily available, are valued at
fair value on a consistent basis using methods determined in good faith by the
Board of Trustees of each Fund.

  Each Fund determines and makes available for publication the net asset value
of its Common Shares weekly. Currently, the net asset values of shares of
publicly traded closed-end investment companies investing in debt securities
are published in Barron's, the Monday edition of The Wall Street Journal, and
the Monday and Saturday editions of The New York Times.

Capital Shares

  Each of the Funds has outstanding both Common Shares and AMPS. The Common
Shares of MuniYield Pennsylvania and MuniVest Pennsylvania are traded on the
NYSE, while the Common Shares of MuniHoldings Pennsylvania are traded on the
AMEX. The MuniYield Pennsylvania Common Shares commenced trading on the NYSE
on November 4, 1992. As of September 30, 1999, the net asset value per
MuniYield Pennsylvania Common Share was $13.99 and the market price per share
was $12.5625. The MuniVest Pennsylvania Common Shares commenced trading on the
NYSE on August 16, 1993. As of September 30, 1999, the net asset value per
MuniVest Pennsylvania Common Share was $12.31 and the market price per share
was $11.6875. The MuniHoldings Pennsylvania Common Shares commenced trading on
the AMEX on March 8, 1999. As of September 30, 1999, the net asset value per
MuniHoldings Pennsylvania Common Share was $12.98 and the market price per
share was $12.00.

  The Board of Trustees of each Fund is authorized to issue an unlimited
number of shares of beneficial interest. The Board of Trustees of each of the
Funds may authorize separate classes of shares together with such designations
and powers, preferences and rights, qualifications, limitations and
restrictions as may be determined from time to time by the Trustees. Pursuant
to such authority, the Trustees authorized the issuance of an unlimited number
of Common Shares together with 1,000,000 preferred shares of beneficial
interest. In connection with each respective Fund's offering of AMPS,
MuniYield Pennsylvania issued 1,600 preferred shares as AMPS, MuniVest
Pennsylvania issued 1,100 preferred shares as AMPS and MuniHoldings
Pennsylvania issued 820 shares as AMPS.

  Each Fund is an entity of the type commonly known as a "Massachusetts
business trust." Under Massachusetts law, shareholders of such a trust may,
under certain circumstances, be held personally liable as partners for its
obligations. However, the Declaration of Trust of each Fund contains an
express disclaimer of shareholder liability for acts or obligations of that
Fund and provides for indemnification and reimbursement of expenses out of
that Fund's property for any shareholder held personally liable for the
obligations of that Fund. Thus, the risk of a shareholder incurring financial
loss on account of shareholder liability is limited to circumstances in which
the Funds themselves would be unable to meet their obligations. Given the
nature of the Funds' assets and operations, the possibility of any of the
Funds being unable to meet their obligations is remote and, in the opinion of
Massachusetts counsel to the Funds, the risk to the Funds' shareholders is
remote.

  The Declaration of Trust of each Fund further provides that no Trustee,
officer, employee or agent of that Fund is liable to that Fund or to any
shareholder, nor is any Trustee, officer, employee or agent liable to any
third persons in connection with the affairs of that Fund, except as such
liability may arise from his or her own bad faith, willful misfeasance, gross
negligence, or reckless disregard of their duties. It also provides that all
third persons shall look solely to the Funds' property for satisfaction of
claims arising in connection with the affairs of each Fund. With the
exceptions stated, the Declaration of Trust of each Fund provides that a
Trustee, officer, employee or agent is entitled to be indemnified against all
liability in connection with the affairs of that Fund.

                                      40


 Common Shares

  Holders of each Fund's Common Shares are entitled to share equally in
dividends declared by the Fund's Board of Trustees payable to holders of the
Common Shares and in the net assets of the Fund available for distribution to
holders of the Common Shares after payment of the preferential amounts payable
to holders of any outstanding preferred shares. See "Voting Rights" and
"Liquidation Rights of Holders of AMPS" below. Holders of a Fund's Common
Shares do not have preemptive or conversion rights and a Fund's Common Shares
are not redeemable. The outstanding Common Shares of each Fund are fully paid
and nonassessable.

  So long as any AMPS of a Fund or any other preferred shares are outstanding,
holders of the Fund's Common Shares will not be entitled to receive any
dividends of or other distributions from the Fund unless all accumulated
dividends on the Fund's outstanding AMPS and any other preferred shares have
been paid, and unless asset coverage (as defined in the Investment Company
Act) with respect to such AMPS and any other preferred shares would be at
least 200% after giving effect to such distributions.

 Preferred Shares

  The AMPS of each of the Funds have a similar structure. The AMPS of each
Fund are preferred shares of the Fund that entitle their holders to receive
dividends when, as and if declared by the Board of Trustees, out of funds
legally available therefor, at a rate per annum that may vary for the
successive dividend periods. The AMPS of all of the Funds have liquidation
preferences of $25,000 per share; none of the Fund's AMPS are traded on any
stock exchange or over-the-counter. Each Fund's AMPS can be purchased at an
auction or through broker-dealers who maintain a secondary market in the AMPS.

  Auctions generally have been held and will be held every seven days for the
AMPS of each of the Funds, unless the applicable Fund elects, subject to
certain limitations, to declare a special dividend period. The following table
provides information about the dividend rates for each series of AMPS of each
of the Funds as of a recent auction.



                                                                        Dividend

     October 25, 1999................. MuniHoldings Pennsylvania    A    2.99%

- --------
*No series designation.

  Under the Investment Company Act, each Fund is permitted to have outstanding
more than one series of preferred shares as long as no single series has
priority over another series as to the distribution of assets of the Fund or
the payment of dividends. Holders of a Fund's preferred shares do not have
preemptive rights to purchase any shares of AMPS or any other preferred shares
that might be issued. The net asset value per share of a Fund's AMPS equals
its liquidation preference plus accumulated dividends per share.

  The redemption provisions pertaining to the AMPS of each Fund are
substantially similar. It is anticipated that shares of AMPS of each Fund will
generally be redeemable at the option of the Fund at a price equal to their
liquidation preference of $25,000 per share plus accumulated but unpaid
dividends (whether or not earned or declared) to the date of redemption plus,
under certain circumstances, a redemption premium. AMPS will also be subject
to mandatory redemption at a price equal to their liquidation preference plus
accumulated but unpaid dividends (whether or not earned or declared) to the
date of redemption upon the occurrence of certain specified events, such as
the failure of the Fund to maintain the asset coverage for the AMPS specified
by Moody's and S&P in connection with their issuance of ratings on the AMPS.

                                      41


 Certain Provisions of the Declaration of Trust

  Each Fund's Declaration of Trust includes provisions that could have the
effect of limiting the ability of other entities or persons to acquire control
of the Fund or to change the composition of its Board of Trustees and could
have the effect of depriving shareholders of an opportunity to sell their
shares at a premium over prevailing market prices by discouraging a third
party from seeking to obtain control of the Fund. A Trustee may be removed
from office with or without cause by vote of the holders of at least 66 2/3%
of the votes entitled to be voted on the matter. A Trustee elected by all of
the holders of capital stock may be removed only by action of such holders,
and a Trustee elected by the holders of AMPS and any other preferred shares
may be removed only by action of the holders of AMPS and any other preferred
shares.

  In addition, the Declaration of Trust of each Fund requires the favorable
vote of the holders of at least 66 2/3% of all of the Fund's shares of capital
stock, then entitled to be voted, voting as a single class, to approve, adopt
or authorize the following:

  .  a merger or consolidation or statutory share exchange of the Fund with
     any other corporation or entity,

  .  a sale of all or substantially all of the Fund's assets (other than in
     the regular course of the Fund's investment activities), or

  .  a liquidation or dissolution of the Fund,

unless such action has been approved, adopted or authorized by the affirmative
vote of at least two-thirds of the total number of Trustees fixed in
accordance with the by-laws, in which case the affirmative vote of a majority
of all of the votes entitled to be cast by shareholders of the Fund, voting as
a single class, is required. Such approval, adoption or authorization of the
foregoing also would require the favorable vote of at least a majority of the
Fund's preferred shares then entitled to be voted thereon, including the AMPS,
voting as a separate class.

  In addition, conversion of a Fund to an open-end investment company would
require an amendment to the Fund's Declaration of Trust. The amendment would
have to be declared advisable by the Board of Trustees prior to its submission
to shareholders. Such an amendment would require the affirmative vote of the
holders of at least 66 2/3% of the Fund's outstanding capital shares
(including the AMPS and any other preferred shares) entitled to be voted on
the matter, voting as a single class (or a majority of such shares if the
amendment was previously approved, adopted or authorized by at least two-
thirds of the total number of Trustees fixed in accordance with the by-laws),
and the affirmative vote of at least a majority of outstanding preferred
shares of a Fund (including the AMPS), voting as a separate class. Such a vote
also would satisfy a separate requirement in the Investment Company Act that
the change be approved by the shareholders. Shareholders of an open-end
investment company may require the company to redeem their Common Shares at
any time (except in certain circumstances as authorized by or under the
Investment Company Act) at their net asset value, less such redemption charge,
if any, as might be in effect at the time of a redemption. All redemptions
will be made in cash. If the Fund is converted to an open-end investment
company, it could be required to liquidate portfolio securities to meet
requests for redemption and the Common Shares no longer would be listed on a
stock exchange. Conversion to an open-end investment company would also
require redemption of all outstanding preferred shares (including the AMPS)
and would require changes in certain of the Fund's investment policies and
restrictions, such as those relating to the issuance of senior securities, the
borrowing of money and the purchase of illiquid securities.

  The Board of Trustees of each Fund has determined that the 66 2/3% voting
requirements described above, which are greater than the minimum requirements
under Massachusetts law or the Investment Company Act, are in the best
interests of shareholders generally. Reference should be made to the
Declaration of Trust of each Fund on file with the SEC for the full text of
these provisions.

Management of the Funds

  Trustees and Officers. The Boards of Trustees of MuniVest Pennsylvania and
MuniHoldings Pennsylvania currently consist of the same seven persons, five of
whom are not "interested persons," as defined in the Investment Company Act,
of any of those Funds. The Board of Trustees of MuniYield Pennsylvania
currently consists of nine persons, seven of whom are not "interested persons"
of MuniYield Pennsylvania. Terry K. Glenn serves as a Trustee and President of
each of the Funds and Arthur Zeikel serves as a Trustee of each of the Funds.
The Trustees of each Fund are responsible for the overall supervision of the
operations of the Fund and perform the various duties imposed on the trustees
of investment companies by the Investment Company Act and under applicable
Massachusetts law. The Funds have the same slate of officers with a few
exceptions. For further information regarding the Trustees and officers of
each Fund, see "Item 2.: Election of Trustees" and Exhibit I--"Information
Pertaining to Each Fund."

  William R. Bock serves as the portfolio manager for MuniYield Pennsylvania
and MuniVest Pennsylvania. Robert A. DiMella and William R. Bock serve as the
portfolio managers for MuniHoldings Pennsylvania. Mr. Bock will continue to
serve as the portfolio manager of the combined fund after the Reorganization.
The portfolio managers are primarily responsible for the management of the
applicable Fund's portfolio. Biographical information about Messrs. DiMella,
and Bock is contained in Exhibit I--"Information Pertaining to Each Fund."

  Management and Advisory Arrangements. FAM, which is owned and controlled by
ML & Co., serves as the investment adviser for each of the Funds pursuant to
separate investment advisory agreements that, except for their termination
dates and advisory fee rates, are identical. FAM provides each Fund with the
same investment advisory and management services. The Asset Management Group
of ML & Co. (which includes FAM) acts as the investment adviser to more than
100 registered investment companies and offers services to individuals and
institutional accounts. As of September 1999, the Asset Management Group had a
total of approximately $514 billion in investment company and other portfolio
assets under management (approximately $38.5 billion of which were invested in
municipal securities). This amount includes assets managed for certain
affiliates of FAM. FAM is a limited partnership, the partners of which are ML
& Co. and Princeton Services, Inc. FAM was organized as an investment adviser
in 1977 and offers investment advisory services to more than 50 registered
investment companies. The principal business address of FAM is 800 Scudders
Mill Road, Plainsboro, New Jersey 08536.

  Each Fund's investment advisory agreement with FAM provides that, subject to
the supervision of the Board of Trustees of the Fund, FAM is responsible for
the actual management of the Fund's portfolio. The responsibility for making
decisions to buy, sell or hold a particular security for each Fund rests with
FAM, subject to review by the Board of Trustees of the Fund.

  FAM provides the portfolio management for each of the Funds. Such portfolio
management considers analyses from various sources (including brokerage firms
with which each Fund does business), makes the necessary investment decisions,
and places orders for transactions accordingly. FAM also is responsible for
the performance of certain administrative and management services for each
Fund.

  For the services provided by FAM under the investment advisory agreements,
MuniYield Pennsylvania and MuniVest Pennsylvania currently pay FAM, a monthly
fee at the annual rate of 0.50% of each Fund's average weekly net assets, and
MuniHoldings Pennsylvania currently pays a monthly fee at an annual rate of
0.55% of the Fund's average weekly net assets. After the Reorganization, the
combined fund will pay FAM a monthly fee at the annual rate of .50% of the
combined fund's average weekly net assets. "Average weekly net assets" refers
to the average weekly value of the total assets of the Fund, including assets
acquired from the sale of preferred shares, minus the sum of accrued
liabilities of the Fund and accumulated dividends on its preferred shares. For
purposes of this calculation, average weekly net assets are determined at the
end of each month on the basis of the average net assets of the Fund for each
week during the month. The assets for each weekly period are determined by
averaging the net assets at the last business day of a week with the net
assets at the last business day of the prior week. For MuniHoldings
Pennsylvania, approval of the Reorganization represents a fee reduction.


                                      43


  Each Fund's investment advisory agreement obligates FAM to provide
investment advisory services and to pay all compensation of and furnish office
space for officers and employees of the Fund connected with investment and
economic research, trading and investment management of the Fund, as well as
the compensation of all Trustees of the Fund who are affiliated persons of FAM
or any of its affiliates. Each Fund pays all other expenses incurred in the
operation of the Fund, including, among other things, expenses for legal and
auditing services, taxes, costs of printing proxies, listing fees, share
certificates and shareholder reports, charges of the custodian and the
transfer agent, dividend disbursing agent and registrar, fees and expenses
with respect to the issuance of AMPS, SEC fees, fees and expenses of
unaffiliated Trustees, accounting and pricing costs, insurance, interest,
brokerage costs, litigation and other extraordinary or non-recurring expenses,
mailing and other expenses properly payable by the Fund. FAM provides
accounting services to each Fund, and each Fund reimburses FAM for its
respective costs in connection with such services.

  Unless earlier terminated as described below, the investment advisory
agreement between each Fund and FAM will continue from year to year if
approved annually (a) by the Board of Trustees of the Fund or by a majority of
the outstanding Common Shares and AMPS of the Fund, voting together as a
single class, and (b) by a majority of the Trustees of the Fund who are not
parties to such contract or "interested persons," as defined in the Investment
Company Act, of any such party. The contract is not assignable and it may be
terminated without penalty on 60 days' written notice at the option of either
party thereto or by the vote of the shareholders of the Fund.

  Securities held by a Fund may also be held by, or be appropriate investments
for, other funds or investment advisory clients for which FAM or its
affiliates act as an adviser. Because of different objectives or other
factors, a particular security may be bought for an advisory client when other
clients are selling the same security. If purchases or sales of securities by
FAM for a Fund or other funds for which it acts as investment adviser or for
advisory clients arise for consideration at or about the same time,
transactions in such securities will be made, insofar as feasible, for the
respective funds and clients in a manner deemed equitable to all. Transactions
effected by FAM (or its affiliates) on behalf of more than one of its clients
during the same period may increase the demand for securities being purchased
or the supply of securities being sold, causing an adverse effect on price.

Code of Ethics

  The Board of Trustees of each of the Funds has adopted a Code of Ethics
pursuant to Rule 17j-1 under the Investment Company Act that incorporates the
Code of Ethics of FAM (together, the "Codes"). The Codes significantly
restrict the personal investing activities of all employees of FAM and, as
described below, impose additional, more onerous, restrictions on Fund
investment personnel.

  The Codes require that all employees of FAM preclear any personal securities
investment (with limited exceptions, such as U.S. Government securities). The
preclearance requirement and associated procedures are designed to identify
any substantive prohibition or limitation applicable to the proposed
investment. The substantive restrictions applicable to all employees of FAM
include a ban on acquiring any securities in a "hot" initial public offering
and a prohibition from profiting on short-term trading securities. In
addition, no employee may purchase or sell any security that at the time is
being purchased or sold (as the case may be), or to the knowledge of the
employee is being considered for purchase or sale, by any fund advised by FAM.
Furthermore, the Codes provide for trading "blackout periods" that prohibit
trading by investment personnel of each of the Funds within periods of trading
by the Fund in the same (or equivalent) security (15 or 30 days depending upon
the transaction).

Voting Rights

  Voting rights are identical for the holders of each Fund's Common Shares.
Holders of each Fund's Common Shares are entitled to one vote for each share
held and will vote with the holders of any of the Fund's outstanding AMPS or
other preferred shares on each matter submitted to a vote of holders of Common
Shares, except as set forth below.

                                      44



  Voting rights of the holders of each Fund's AMPS are identical. Except as
otherwise indicated below, and except as otherwise required by applicable law,
holders of a Fund's AMPS will be entitled to one vote per share on each matter
submitted to a vote of the Fund's shareholders and will vote together with the
holders of Common Shares of the Fund as a single class.

  Each Fund's Common Shares, AMPS and any other preferred shares do not have
cumulative voting rights, which means that the holders of more than 50% of a
Fund's Common Shares, AMPS and any other preferred shares voting for the
election of Trustees can elect all of the Trustees standing for election by
such holders, and, in such event, the holders of a Fund's remaining Common
Shares, AMPS and any other preferred shares will not be able to elect any of
such Trustees.

  In connection with the election of a Fund's Trustees, holders of a Fund's
AMPS, voting separately as a class, shall be entitled at all times to elect
two of the Fund's Trustees, and the remaining Trustees will be elected by
holders of Common Shares of the Fund and the Fund's AMPS and any other
preferred shares, voting together as a single class. In addition, if at any
time dividends on a Fund's outstanding AMPS shall be unpaid in an amount equal
to at least two full years' dividends thereon or if at any time holders of any
of a Fund's preferred shares are entitled, together with the holders of the
Fund's AMPS, to elect a majority of the Trustees of the Fund under the
Investment Company Act, then the number of Trustees constituting the Board of
Trustees automatically shall be increased by the smallest number that, when
added to the two Trustees elected exclusively by the holders of AMPS and any
other preferred shares as described above, would constitute a majority of the
Board of Trustees as so increased by such smallest number, and at a special
meeting of shareholders which will be called and held as soon as practicable,
and at all subsequent meetings at which Trustees are to be elected, the
holders of shares of the Fund's AMPS and any other preferred shares, voting
separately as a class, will be entitled to elect the smallest number of
additional Trustees that, together with the two Trustees which such holders in
any event will be entitled to elect, constitutes a majority of the total
number of Trustees of the Fund as so increased. The terms of office of the
persons who are Trustees at the time of that election will continue. If the
Fund thereafter shall pay, or declare and set apart for payment in full, all
dividends payable on all outstanding AMPS and any other preferred shares for
all past dividend periods, the additional voting rights of the holders of AMPS
and any other preferred shares as described above shall cease, and the terms
of office of all of the additional Trustees elected by the holders of AMPS and
any other preferred shares (but not of the Trustees with respect to whose
election the holders of Common Shares were entitled to vote or the two
Trustees the holders of AMPS and any other preferred shares have the right to
elect in any event) will terminate automatically.

  The affirmative vote of the holders of a majority of a Fund's outstanding
AMPS, voting as a separate class, will be required to (i) authorize, create or
issue any class or series of shares ranking prior to any series of preferred
shares with respect to payment of dividends or the distribution of assets on
liquidation, (ii) amend, alter or repeal the provisions of the Declaration of
Trust, whether by merger, consolidation or otherwise, so as to adversely
affect any of the contract rights expressly set forth in the Declaration of
Trust of holders of preferred shares, (iii) approve any plan of reorganization
adversely affecting such AMPS or (iv) take any action to change a Fund's
investment policies requiring a vote of shareholders under Section 13(a) of
the Investment Company Act.

Shareholder Inquiries

  Shareholder inquiries with respect to any of the Funds may be addressed to
such Fund by telephone at (609) 282-2800 or at the address set forth on the
cover page of this Proxy Statement and Prospectus.

Dividends and Distributions

  The Funds' current policies with respect to dividends relating to their
Common Shares are identical. Each Fund intends to distribute all or a portion
of its net investment income monthly to holders of a Fund's Common Shares.
Monthly distributions to holders of a Fund's Common Shares normally consist of
all or a portion of its net investment income remaining after the payment of
dividends (and any Additional Distribution) on the Fund's

                                      45



AMPS. A Fund may at times pay out less than the entire amount of net
investment income earned in any particular period and may at times pay out
such accumulated undistributed income in addition to net investment income
earned in other periods in order to permit the Fund to maintain a more stable
level of dividends to holders of Common Shares. As a result, the dividend paid
by a Fund to holders of its Common Shares for any particular period may be
more or less than the amount of net investment income earned by the Fund
during such period. For Federal tax purposes, the Fund is required to
distribute substantially all of its net investment income for each year. All
net realized capital gains, if any, are distributed pro rata at least annually
to holders of a Fund's Common Shares and AMPS. While any of a Fund's AMPS are
outstanding, the Fund may not declare any cash dividend or other distribution
on the Fund's Common Shares, unless at the time of such declaration (1) all
accumulated dividends on the Fund's AMPS, including any Additional
Distribution, have been paid, and (2) the net asset value of the Fund's
portfolio (determined after deducting the amount of such dividend or other
distribution) is at least 200% of the liquidation value of the Fund's
outstanding AMPS. If a Fund's ability to make distributions on its Common
Shares is limited, such limitation could under certain circumstances, impair
the ability of the Fund to maintain its qualification for taxation as a
regulated investment company which would have adverse tax consequences for
shareholders. See "Comparison of the Funds--Tax Rules Applicable to the Funds
and their Shareholders."

  Similarly, the Funds' current policies with respect to dividends and
distributions on their AMPS are identical. The holders of a Fund's AMPS are
entitled to receive, when, as and if declared by the Board of Trustees of the
Fund, out of funds legally available therefor, cumulative cash dividends on
their shares. Dividends on a Fund's AMPS so declared and payable shall be paid
(i) in preference to and in priority over any dividends so declared and
payable on the Fund's Common Shares, and (ii) to the extent permitted under
the Code and to the extent available, out of net tax-exempt income earned on
the Fund's investments. Dividends for each Fund's AMPS are paid through The
Depository Trust Company ("DTC") (or a successor securities depository) on
each dividend payment date. DTC's normal procedures now provide for it to
distribute dividends in same-day funds to agent members, who in turn are
expected to distribute such dividends to the person for whom they are acting
as agent in accordance with the instructions of such person. Prior to each
dividend payment date, the relevant Fund is required to deposit with the
Auction Agent sufficient funds for the payment of such declared dividends.
None of the Funds intends to establish any reserves for the payment of
dividends, and no interest will be payable in respect of any dividend payment
or payment on a Fund's AMPS which may be in arrears.

  Dividends paid by each Fund, to the extent paid from tax-exempt income
earned on Pennsylvania Municipal Bonds, are exempt from Federal income tax and
Pennsylvania personal income taxes, subject to the possible application of the
Federal alternative minimum tax. However, each Fund is required to allocate
net capital gains and other income subject to regular Federal income tax, if
any, proportionately between its Common Shares and its AMPS in accordance with
the current position of the IRS described herein. Such allocation will also
apply for Pennsylvania personal income tax purposes. See "Tax Rules Applicable
to the Funds and their Shareholders" below. Each Fund notifies the Auction
Agent of the amount of any net capital gains or other taxable income to be
included in any dividend on AMPS prior to the auction establishing the
applicable rate for such dividend. The Auction Agent in turn notifies each
broker-dealer whenever it receives any such notice from a Fund, and each
broker-dealer then notifies its customers who are holders of the Fund's AMPS.
Each Fund also may include such income in a dividend on shares of its AMPS
without giving advance notice thereof if it increases the dividend by an
additional amount to offset the tax effect thereof. The amount of taxable
income allocable to a Fund's AMPS will depend upon the amount of such income
realized by the Fund and other factors, but generally is not expected to be
significant.

  For information concerning the manner in which dividends and distributions
to each Fund's holders of Common Shares may be reinvested automatically in the
Fund's Common Shares, see "Automatic Dividend Reinvestment Plan" below.
Dividends and distributions will be subject to the tax treatment discussed
below, whether they are reinvested in shares of a Fund or received in cash.


                                      46


  If any Fund retroactively allocates any net capital gains or other income
subject to regular Federal income tax and Pennsylvania personal income taxes
to shares of its AMPS without having given advance notice thereof as described
above, which only may happen when such allocation is made as a result of the
redemption of all or a portion of its outstanding AMPS or the liquidation of
the Fund, the Fund will make certain payments to holders of its AMPS to which
such allocation was made to offset substantially the tax effect thereof. In no
other instances will the Fund be required to make payments to holders of its
AMPS to offset the tax effect of any reallocation of net capital gains or
other taxable income.

Automatic Dividend Reinvestment Plan

  Pursuant to each Fund's Automatic Dividend Reinvestment Plan (each, a
"Plan"), unless a holder of a Fund's Common Shares elects otherwise, all
dividend and capital gains distributions are automatically reinvested by
either The Bank of New York or State Street Bank and Trust Company, as
applicable, as agent for shareholders in administering the Plan (as
applicable, the "Plan Agent"), in additional Common Shares of the Fund. The
Bank of New York is the Plan Agent for MuniVest Pennsylvania and MuniHoldings
Pennsylvania, while State Street Bank and Trust Company is the Plan Agent for
MuniYield Pennsylvania and will be the Plan Agent following the
Reorganization. Holders of a Fund's Common Shares who elect not to participate
in the Plan receive all distributions in cash paid by check mailed directly to
the shareholder of record (or, if the shares are held in street or other
nominee name, then to such nominee) by The Bank of New York or State Street
Bank and Trust Company, as applicable, as dividend paying agent. Such
shareholders may elect not to participate in the Plan and to receive all
distributions of dividends and capital gains in cash by sending written
instructions to The Bank of New York or State Street Bank and Trust Company,
as applicable, as dividend paying agent, at the address set forth below.
Participation in the Plan is completely voluntary and may be terminated or
resumed at any time without penalty by written notice if received by the Plan
Agent not less than ten days prior to any dividend record date; otherwise,
such termination or resumption will be effective with respect to any
subsequently declared dividend or capital gains distribution.

  Whenever a Fund declares an ordinary income dividend or a capital gain
dividend (collectively referred to as "dividends") payable either in shares or
in cash, non-participants in the Plan receive cash, and participants in the
Plan receive the equivalent in the Fund's Common Shares. The shares are
acquired by the Plan Agent for the participant's account, depending upon the
circumstances described below, either (i) through receipt of additional
unissued but authorized Common Shares from the Fund ("newly-issued shares") or
(ii) by purchase of outstanding Common Shares of the Fund on the open market
("open-market purchases"), on the NYSE or elsewhere. If on the payment date
for the dividend, the net asset value per share of the Fund's Common Shares is
equal to or less than the market price per share of the Fund's Common Shares
plus estimated brokerage commissions (such condition being referred to herein
as "market premium"), the Plan Agent invests the dividend amount in newly-
issued shares on behalf of the participant. The number of newly-issued shares
of the Fund's Common Shares to be credited to the participant's account is
determined by dividing the dollar amount of the dividend by the net asset
value per share on the date the shares are issued, provided that the maximum
discount from the then-current market price per share on the date of issuance
may not exceed 5%. If on the dividend payment date, the net asset value per
share is greater than the market value (such condition being referred to
herein as "market discount"), the Plan Agent invests the dividend amount in
shares acquired on behalf of the participant in open-market purchases.

  In the event of a market discount on the dividend payment date, the Plan
Agent has until the last business day before the next date on which the shares
trade on an "ex-dividend" basis or in no event more than 30 days after the
dividend payment date (the "last purchase date") to invest the dividend amount
in shares acquired in open-market purchases. Each Fund intends to pay monthly
income dividends. Therefore, the period during which open-market purchases can
be made exists only from the payment date on the dividend through the date
before the next "ex-dividend" date, which typically is approximately ten days.
If, before the Plan Agent has completed its open-market purchases, the market
price of a share of a Fund's Common Shares exceeds the net asset value per
share, the average per share purchase price paid by the Plan Agent may exceed
the net asset value of the Fund's Common Shares, resulting in the acquisition
of fewer shares than if the dividend had been paid in newly-

                                      47


issued shares on the dividend payment date. Because of the foregoing
difficulty with respect to open-market purchases, the Plan provides that if
the Plan Agent is unable to invest the full dividend amount in open-market
purchases during the purchase period or if the market discount shifts to a
market premium during the purchase period, the Plan Agent ceases making open-
market purchases and invests the uninvested portion of the dividend amount in
newly-issued shares at the close of business on the last purchase date.

  The Plan Agent maintains all shareholders' accounts in the Plan and
furnishes written confirmation of all transactions in the account, including
information needed by shareholders for tax records. Shares in the account of
each Plan participant are held by the Plan Agent in non-certificated form in
the name of the participant, and each shareholder's proxy includes those
shares purchased or received pursuant to the Plan. The Plan Agent will forward
all proxy solicitation materials to participants and vote proxies for shares
held pursuant to the Plan in accordance with the instructions of the
participants.

  In the case of shareholders such as banks, brokers or nominees which hold
shares for others who are the beneficial owners, the Plan Agent will
administer the Plan on the basis of the number of shares certified from time
to time by the record shareholders as representing the total amount registered
in the record shareholder's name and held for the account of beneficial owners
who are to participate in the Plan.

  There are no brokerage charges with respect to shares issued directly by any
Fund as a result of dividends or capital gains distributions payable either in
shares or in cash. However, each participant pays a pro rata share of
brokerage commissions incurred with respect to the Plan Agent's open-market
purchases in connection with the reinvestment of dividends.

  The automatic reinvestment of dividends and distributions does not relieve
participants of any Federal, state or local income tax that may be payable (or
required to be withheld) on such dividends. See "Comparison of the Funds--Tax
Rules Applicable to the Funds and their Shareholders".

  Shareholders participating in the Plan may receive benefits not available to
shareholders not participating in the Plan. If the market price (plus
commissions) of a Fund's Common Shares is higher than net asset value,
participants in the Plan receive shares of the Fund's Common Shares at less
than they otherwise could purchase them and have shares with a cash value
greater than the value of any cash distribution they would have received on
their shares. If the market price plus commissions is less than net asset
value, participants receive distributions of shares with a net asset value
greater than the value of any cash distribution they would have received on
their shares. However, there may be insufficient shares available in the
market to make distributions of shares at prices below the net asset value.
Also, since the Funds normally do not redeem their shares, the price on resale
may be more or less than the net asset value. See "Comparison of the Funds--
Tax Rules Applicable to the Funds and their Shareholders" for a discussion of
the tax consequences of the Plan.

  Each Fund reserves the right to amend or terminate its Plan. There is no
direct service charge to participants in the Plan; however, each Fund reserves
the right to amend its Plan to include a service charge payable by the
participants.

  After the Reorganization, a holder of shares of an Acquired Fund who has
elected to receive dividends in cash will continue to receive dividends in
cash; all other holders will have their dividends automatically reinvested in
shares of the combined fund. However, if a shareholder owns shares in an
Acquired Fund and in MuniYield Pennsylvania, after the Reorganization, the
shareholder's election with respect to the dividends of MuniYield Pennsylvania
will control unless the shareholder specifically elects a different option at
that time. Following the Reorganization, all correspondence should be directed
to the Plan Agent, State Street Bank and Trust Company, at 225 Franklin
Street, Boston, Massachusetts 02110.

Mutual Fund Investment Option

  A holder of Common Shares of any Fund, who purchased his or her shares
through Merrill Lynch in the Fund's initial public offering, has the right to
reinvest the net proceeds from a sale of such shares in Class A

                                      48



shares (in the case of MuniYield Pennsylvania and MuniVest Pennsylvania
shareholders) and Class D shares (in the case of MuniHoldings Pennsylvania
shareholders) of certain Merrill Lynch-sponsored open-end funds without the
imposition of an initial sales charge, if certain conditions are satisfied.
Class D shares pay an ongoing account maintenance fee. A holder of Common
Shares of an Acquired Fund who qualifies for this option will continue to have
this option after consummation of the Reorganization. Thus after the
Reorganization, qualifying shareholders of MuniYield Pennsylvania and MuniVest
Pennsylvania will retain their option with respect to Class A shares, while
qualifying shareholders of MuniHoldings Pennsylvania will retain their option
with respect to Class D shares.

Liquidation Rights of Holders of AMPS

  Upon any liquidation, dissolution or winding up of any Fund, whether
voluntary or involuntary, the holders of the Fund's AMPS will be entitled to
receive, out of the assets of the Fund available for distribution to
shareholders, before any distribution or payment is made upon any of the
Fund's Common Shares or any other capital stock of the Fund ranking junior in
right of payment upon liquidation to AMPS, $25,000 per share together with the
amount of any dividends accumulated but unpaid (whether or not earned or
declared) thereon to the date of distribution, and after such payment the
holders of AMPS will be entitled to no other payments except for any
additional dividends. If such assets of the Fund shall be insufficient to make
the full liquidation payment on the AMPS and liquidation payments on any other
outstanding class or series of preferred shares of the Fund ranking on a
parity with the AMPS as to payment upon liquidation, then such assets will be
distributed among the holders of AMPS and the holders of shares of such other
class or series ratably in proportion to the respective preferential amounts
to which they are entitled. After payment of the full amount of liquidation
distribution to which they are entitled, the holders of a Fund's AMPS will not
be entitled to any further participation in any distribution of assets by the
Fund except for any additional dividends. A consolidation, merger or share
exchange of a Fund with or into any other entity or entities or a sale,
whether for cash, shares of stock, securities or properties, of all or
substantially all or any part of the assets of the Fund shall not be deemed or
construed to be a liquidation, dissolution or winding up of the Fund for this
purpose.

Tax Rules Applicable to the Funds and their Shareholders

  The tax consequences of investing in Common Shares or AMPS of each of the
Funds are identical. MuniYield Pennsylvania and MuniVest Pennsylvania have
elected and qualified for the special tax treatment afforded RICs under the
Code. As a result, in any taxable year in which they distribute an amount
equal to at least 90% of taxable net income and 90% of tax-exempt net income
(see below), the Funds are not subject to Federal income tax to the extent
that they distribute their net investment income and net realized capital
gains. In all taxable years through the taxable year of the Reorganization,
each Fund has distributed substantially all of its income. MuniYield
Pennsylvania intends to continue to distribute substantially all of its income
following the Reorganization.

  Each Fund is qualified to pay "exempt-interest dividends" as defined in
Section 852(b)(5) of the Code. Under such section, if, at the close of each
quarter of its taxable year, at least 50% of the value of a Fund's total
assets consists of obligations the interest on which is excludable from gross
income for Federal income tax purposes ("tax-exempt obligations") under
Section 103(a) of the Code (relating generally to obligations of a state or
local governmental unit), the Fund is qualified to pay exempt-interest
dividends to its shareholders. Exempt-interest dividends are dividends or any
part thereof paid by a Fund which are attributable to interest on tax-exempt
obligations and designated by the Fund as exempt-interest dividends in a
written notice mailed to shareholders within 60 days after the close of its
taxable year. To the extent that the dividends distributed to a Fund's
shareholders are derived from interest income exempt from Federal income tax
under Code Section 103(a) and are properly designated as exempt-interest
dividends, they are excludable from a shareholder's gross income for Federal
income tax purposes. Exempt-interest dividends are included, however, in
determining the portion, if any, of a person's social security benefits and
railroad retirement benefits subject to Federal income taxes. Interest on
indebtedness incurred or continued to purchase or carry a Fund's shares is not
deductible for Federal income tax purposes to the extent attributable to
exempt-interest dividends. A tax adviser should be consulted with respect to
whether exempt-interest dividends retain the exclusion under Code Section
103(a) if a shareholder would be treated as a "substantial user" or "related
person" under Code Section 147(a) with respect to property financed with the
proceeds from an issue of PABs or IDBs if any, held by a Fund.

                                      49


  The portion of exempt-interest dividends paid from interest received by a
Fund from Pennsylvania Municipal Bonds also will be exempt from Pennsylvania
personal income tax. In the case of residents of the City of Philadelphia,
distributions which are derived from interest on Pennsylvania Municipal Bonds
or which are designated as capital gain dividends for Federal income tax
purposes will be exempt from the Philadelphia School District investment
income tax.

  Shares of the Funds will be exempt from the personal property taxes imposed
by various Pennsylvania municipalities to the extent the Funds' portfolio
securities consist of Pennsylvania Municipal Bonds on the annual assessment
date. It should be noted, however, that at present, Pennsylvania counties
generally have stopped assessing personal property taxes. This is due, in
part, to ongoing litigation challenging the validity of the tax.

  Other Pennsylvania counties, cities and townships generally do not tax
individuals on unearned income.

  As a result of a pronouncement by the Pennsylvania Department of Revenue, an
investment in the Funds by a corporate shareholder will apparently qualify as
an exempt asset for purposes of the single asset apportionment fraction
available in computing the Pennsylvania capital stock/foreign franchise tax to
the extent that the portfolio securities of the Funds comprise investments in
Pennsylvania and/or United States Government Securities that would be exempt
assets if owned directly by the corporation. To the extent exempt-interest
dividends are excluded from taxable income for federal corporate income tax
purposes (determined before net operating loss carryovers and special
deductions), they will not be subject to the Pennsylvania corporate net income
tax.

  Shareholders subject to income taxation by states other than Pennsylvania
realize a lower after-tax rate of return than Pennsylvania shareholders since
the dividends distributed by a Fund generally are not exempt, to any
significant degree, from income taxation by such other states or cities. Each
Fund informs its shareholders annually as to the portion of the Fund's
distributions that constitutes exempt-interest dividends and the portion that
is exempt from Pennsylvania personal income taxes. Interest on indebtedness
incurred or continued to purchase or carry a Fund's shares is not deductible
for Federal income tax or Pennsylvania personal income tax purposes to the
extent attributable to exempt-interest dividends.

  The IRS, in a revenue ruling, held that certain AMPS would be treated as
stock for Federal income tax purposes. The terms of the currently outstanding
AMPS of each of the Funds, as well as the Series B AMPS to be issued by
MuniYield Pennsylvania, are substantially similar, but not identical, to the
AMPS discussed in the revenue ruling. In the opinion of Brown & Wood LLP,
counsel to all three Funds, each Fund's currently outstanding AMPS, as well as
the Series B AMPS to be issued by MuniYield Pennsylvania, constitute stock,
and distributions with respect such AMPS (other than distributions in
redemption of AMPS subject to Section 302(b) of the Code) will constitute
dividends to the extent of current and accumulated earnings and profits as
calculated for Federal income tax purposes. Nevertheless, the IRS (and/or the
Pennsylvania Department of Revenue) could take a contrary position, asserting,
for example, that the AMPS constitute debt. If this position were upheld, the
discussion of the treatment of distributions below would not apply to holders
of AMPS. Instead, distributions by each Fund to holders of shares of its AMPS
would constitute interest, whether or not they exceed the earnings and profits
of the Fund, would be included in full in the income of the recipient and
taxed as ordinary income. Counsel believes that such a position, if asserted
by the IRS, would be unlikely to prevail.

  To the extent that a Fund's distributions are derived from interest on its
taxable investments or from an excess of net short-term capital gains over net
long-term capital losses ("ordinary income dividends"), such distributions are
considered taxable ordinary income for Federal income tax and Pennsylvania
personal income tax purposes. Distributions, if any, from an excess of net
long-term capital gains over net short-term capital losses derived from the
sale of securities or from certain transactions in futures or options
("capital gain dividends")

                                      50


are taxable as long-term capital gains for Federal income tax purposes,
regardless of the length of time the shareholder has owned Fund shares, and
for Pennsylvania personal income tax purposes will be treated as taxable
dividends. Certain categories of capital gains are taxable at different rates
for Federal income tax purposes. Generally not later than 60 days after the
close of its taxable year, a Fund provides its shareholders with a written
notice designating the amounts of any exempt-interest dividends and/or capital
gain dividends, as well as any amount of capital gain dividends in the
different categories of capital gain referred to above. Distributions by a
Fund, whether from exempt-interest income, ordinary income or capital gains,
are not eligible for the dividends received deduction for corporations under
the Code.

  A loss realized on a sale or exchange of shares of a Fund is disallowed for
Federal income tax purposes if other Fund shares are acquired (whether under
the Automatic Dividend Reinvestment Plan or otherwise) within a 61-day period
beginning 30 days before and ending 30 days after the date that the shares are
disposed of. In such a case, the basis of the shares acquired will be adjusted
to reflect the disallowed loss.

  All or a portion of a Fund's gain from the sale or redemption of tax-exempt
obligations purchased at a market discount will be treated as ordinary income
rather than capital gain for Federal income tax purposes. This rule may
increase the amount of ordinary income dividends received by shareholders. Any
loss upon the sale or exchange of Fund shares held for six months or less is
treated as long-term capital loss for Federal income tax purposes to the
extent of exempt-interest dividends received by the shareholder. In addition,
such loss is disallowed to the extent of any capital gain dividends received
by the shareholder. Distributions in excess of a Fund's earnings and profits
first will reduce the adjusted tax basis of a holder's shares and, after such
adjusted tax basis is reduced to zero, will constitute capital gains to such
holder (assuming the shares are held as a capital asset). If a Fund pays a
dividend in January which was declared in the previous October, November or
December to shareholders of record on a specified date in one of such months,
then such dividend is treated for Federal income tax purposes as paid by the
Fund and received by its shareholders on December 31 of the year in which such
dividend was declared.

  The IRS has taken the position in a revenue ruling that if a RIC has two or
more classes of shares it may designate distributions made to each class in
any year as consisting of no more than such class's proportionate share of
particular types of income, including exempt-interest dividends and capital
gain dividends. A class's proportionate share of a particular type of income
is determined according to the percentage of total dividends paid by the RIC
during such year that was paid to such class. Consequently, when Common Shares
and one or more series of AMPS are outstanding, each Fund intends to designate
distributions made to the classes as consisting of particular types of income
in accordance with each class's proportionate share of such income. After the
Reorganization, MuniYield Pennsylvania will, likewise, so designate
distributions with respect to its Common Shares and its AMPS, Series A and B.
Each Fund may notify the Auction Agent of the amount of any net capital gains
and other taxable income to be included in any dividend on shares of its AMPS
prior to the auction establishing the applicable rate for such dividend.
Except for the portion of any dividend that a Fund informs the Auction Agent
will be treated as capital gains or other taxable income, the dividends paid
on the AMPS constitute exempt-interest dividends. Alternatively, each Fund may
include such income in a dividend on its AMPS without giving advance notice
thereof if it increases the dividend by an additional amount to offset the tax
effect thereof. The amount of net capital gains and ordinary income allocable
to a Fund's AMPS (the "taxable distribution") depends upon the amount of such
gains and income realized by the Fund and the total dividends paid by the Fund
on its Common Shares and shares of its AMPS during a taxable year, but the
taxable distribution generally is not significant.

  In the opinion of Brown & Wood LLP, counsel to all three Funds, under
current law the manner in which each Fund allocates, and MuniYield
Pennsylvania will allocate, items of tax-exempt income, net capital gains, and
other taxable income, if any, among Common Shares and outstanding AMPS
(including, for MuniYield Pennsylvania, AMPS to be designated Series A and the
newly issued Series B AMPS) will be respected for Federal income tax purposes.
However, the tax treatment of additional dividends may affect a Fund's
calculation of each class' allocable share of capital gains and other taxable
income. In addition, there is currently no direct guidance from the IRS or
other sources specifically addressing whether a Fund's method for allocating
tax-

                                      51


exempt income, net capital gains and other taxable income among Common Shares
and the outstanding series of AMPS will be respected for Federal income tax
purposes, and it is possible that the IRS could disagree with counsel's
opinion and attempt to reallocate a Fund's net capital gains or other taxable
income. In the event of a reallocation, some of the dividends identified by a
Fund as exempt-interest dividends to holders of shares of its AMPS could be
recharacterized as additional capital gains or other taxable income. In the
event of such recharacterization, a Fund is not required to make payments to
such shareholders to offset the tax effect of such reallocation. In addition,
a reallocation could cause a Fund to be liable for income tax and excise tax
on all reallocated taxable income. Brown & Wood LLP has advised each Fund
that, in its opinion, if the IRS were to challenge in court a Fund's
allocations of income and gain, the IRS would be unlikely to prevail. The
opinion of Brown & Wood LLP, however, represents only its best legal judgment
and is not binding on the IRS or the courts. Similarly, there is no guidance
from the Pennsylvania Department of Revenue addressing the method of
allocating tax-exempt income, net capital gains and other taxable income among
the Common Shares and the outstanding series of AMPS, and it is possible that
the Pennsylvania Department of Revenue could also attempt to reallocate such
items.

  The Code requires a RIC to pay a nondeductible 4% excise tax to the extent
it does not distribute during each calendar year 98% of its ordinary income,
determined on a calendar year basis, and 98% of its capital gains, determined
in general, on an October 31 year-end, plus certain undistributed amounts from
previous years. The required distributions, however, are based only on the
taxable income of a RIC. The excise tax, therefore, generally does not apply
to the tax-exempt income of RICs, such as the Funds, that pay exempt-interest
dividends.

  The Code subjects interest received on certain otherwise tax-exempt
securities to a Federal alternative minimum tax. The alternative minimum tax
applies to interest received on "private activity bonds" issued after August
7, 1986. "Private activity bonds" are bonds which, although tax-exempt, are
used for purposes other than those generally performed by governmental units
and which benefit non-governmental entities (e.g., bonds used for industrial
development or housing purposes). Income received on such bonds is classified
as an item of "tax preference" which could subject investors in such bonds,
including shareholders of the Funds, to an increased Federal alternative
minimum tax. Each Fund purchases such "private activity bonds" and reports to
shareholders within 60 days after calendar year-end the portion of its
dividends declared during the year which constitutes an item of tax preference
for alternative minimum tax purposes. The Code further provides that
corporations are subject to a Federal alternative minimum tax based, in part,
on certain differences between taxable income as adjusted for other tax
preferences and the corporation's "adjusted current earnings" which more
closely reflect a corporation's economic income. Because an exempt-interest
dividend paid by a Fund is included in adjusted current earnings, a corporate
shareholder may be required to pay a Federal alternative minimum tax on
exempt-interest dividends paid by such Fund.

  The Funds may invest in instruments the return on which includes
nontraditional features such as indexed principal or interest payments
("nontraditional instruments"). These instruments may be subject to special
tax rules under which a Fund may be required to accrue and distribute income
before amounts due under the obligations are paid. In addition, it is possible
that all or a portion of the interest payments on such nontraditional
instruments could be recharacterized as taxable ordinary income.

  If at any time when AMPS are outstanding a Fund does not meet the asset
coverage requirements of the Investment Company Act, the Fund will be required
to suspend distributions to holders of Common Shares until the asset coverage
is restored. See "Dividends and Distributions." This may prevent such Fund
from distributing at least 90% of its net investment income and may,
therefore, jeopardize the Fund's qualification for taxation as a RIC. If a
Fund were to fail to qualify as a RIC, some or all of the distributions paid
by the Fund would be fully taxable to shareholders for Federal income and
Pennsylvania personal income tax purposes. Upon any failure to meet the asset
coverage requirements of the Investment Company Act, a Fund, in its sole
discretion, may redeem AMPS in order to maintain or restore the requisite
asset coverage and avoid the adverse consequences to the Fund and its
shareholders of failing to qualify as a RIC. There can be no assurance,
however, that any such action would achieve such objectives.

                                      52



  As noted above, a Fund must distribute annually at least 90% of its net
taxable and tax-exempt interest income. A distribution will only be counted
for this purpose if it qualifies for the dividends paid deduction under the
Code. Some types of preferred shares that the Funds have issued and that
MuniYield Pennsylvania contemplates issuing may raise a question as to whether
distributions on such preferred shares are "preferential" under the Code and,
therefore, not eligible for the dividends paid deduction. Counsel has advised
the Funds that the outstanding preferred shares and the preferred shares to be
issued by MuniYield Pennsylvania will not result in the payment of a
preferential dividend. If a Fund ultimately relies solely on a legal opinion
when it issues such preferred shares, there is no assurance that the IRS would
agree that dividends on the preferred shares are not preferential. If the IRS
successfully disallowed the dividends paid deduction for dividends on the
preferred shares, the Funds could be disqualified as RICs. In this case,
dividends paid by the Funds on the Common Shares and the AMPS would not be
exempt from Federal income taxes (or, possibly, Pennsylvania income taxes).
Additionally, the Funds would be subject to the Federal alternative minimum
tax.

  Under certain circumstances when a Fund is required to allocate taxable
income to the AMPS, it will pay Additional Distributions to holders of AMPS.
The Federal income tax consequences of Additional Distributions under existing
law are uncertain. The Funds treat and MuniYield Pennsylvania intends to
continue to treat a holder as receiving a dividend distribution in the amount
of any Additional Distribution only as and when such Additional Distribution
is paid. An Additional Distribution generally is designated by a Fund as an
exempt-interest dividend except as otherwise required by applicable law.
However, the IRS may assert that all or part of an Additional Distribution is
a taxable dividend either in the taxable year for which the allocation of
taxable income is made or in the taxable year in which the Additional
Distribution is paid.

  The value of shares acquired pursuant to a Fund's dividend reinvestment plan
is generally excluded from gross income for Federal income tax purposes to the
extent that the cash amount reinvested would be excluded from gross income.
If, when a Fund's shares are trading at a premium over net asset value, the
Fund issues shares pursuant to the dividend reinvestment plan that have a
greater fair market value than the amount of cash reinvested, it is possible
that all or a portion of such discount (which may not exceed 5% of the fair
market value of the Fund's shares) could be viewed as a taxable distribution.
If the discount is viewed as a taxable distribution, it is also possible that
the taxable character of this discount would be allocable to all of the
shareholders, including shareholders who do not participate in the Fund's
dividend reinvestment plan. Thus, shareholders who do not participate in the
dividend reinvestment plan, as well as dividend reinvestment plan
participants, might be required to report as ordinary income a portion of
their distributions equal to the allocable share of the discount.

  Under certain provisions of the Code, some shareholders may be subject to a
31% withholding tax on certain ordinary income dividends and on capital gain
dividends and redemption payments ("backup withholding"). Generally,
shareholders subject to backup withholding will be those for whom no taxpayer
identification number is on file with a Fund or who, to the Fund's knowledge,
have furnished an incorrect number. When establishing an account, an investor
must certify under penalty of perjury that such number is correct and that
such shareholder is not otherwise subject to backup withholding.

  Ordinary income dividends paid to shareholders who are nonresident aliens or
foreign entities are subject to a 30% United States withholding tax under
existing provisions of the Code applicable to foreign individuals and entities
unless a reduced rate of withholding or a withholding exemption is provided
under applicable treaty law. Nonresident shareholders are urged to consult
their own tax advisers concerning the applicability of the United States
withholding tax.

  The Code provides that every shareholder required to file a tax return must
include for information purposes on such return the amount of exempt-interest
dividends received from all sources (including the Funds) during the taxable
year.

  Tax Treatment of Options and Futures Transactions. Each Fund may purchase or
sell municipal bond index financial futures contracts and interest rate
financial futures contracts on U.S. Government securities. Each

                                      53


Fund may also purchase and write call and put options on such financial
futures contracts. In general, unless an election is available to a Fund or an
exception applies, such options and financial futures contracts that are
"Section 1256 contracts" will be "marked to market" for Federal income tax
purposes at the end of each taxable year, i.e., each such option or financial
futures contract will be treated as sold for its fair market value on the last
day of the taxable year, and any gain or loss attributable to Section 1256
contracts will be 60% long-term and 40% short-term capital gain or loss.
Application of these rules to Section 1256 contracts held by a Fund may alter
the timing and character of distributions to shareholders. The mark-to-market
rules outlined above, however, will not apply to certain transactions entered
into by a Fund solely to reduce the risk of changes in price or interest rates
with respect to its investments.

  Code Section 1092, which applies to certain "straddles," may affect the
taxation of a Fund's sales of securities and transactions in financial futures
contracts and related options. Under Section 1092, a Fund may be required to
postpone recognition for tax purposes of losses incurred in certain sales of
securities and certain closing transactions in financial futures contracts or
the related options.

  The foregoing is a general and abbreviated summary of the applicable
provisions of the Code and Treasury Regulations and Pennsylvania tax laws
presently in effect. For the complete provisions, reference should be made to
the pertinent Code sections, the Treasury Regulations promulgated thereunder
and the applicable tax laws. The Code and the Treasury Regulations, as well as
the Pennsylvania tax laws, are subject to change by legislative, judicial or
administrative action either prospectively or retroactively.

  Shareholders are urged to consult their tax advisers regarding specific
questions as to Federal, foreign, state or local tax consequences of an
investment in a Fund.

AGREEMENT AND PLAN OF REORGANIZATION

General

  Under the Agreement and Plan of Reorganization (attached hereto as Exhibit
II), (i) MuniYield Pennsylvania will acquire substantially all of the assets,
and will assume substantially all of the liabilities, of MuniVest
Pennsylvania, in exchange solely for an equal aggregate value of MuniYield
Pennsylvania Common Shares and MuniYield Pennsylvania Series B AMPS to be
issued by MuniYield Pennsylvania, (ii) MuniYield Pennsylvania will acquire
substantially all of the assets, and will assume substantially all of the
liabilities, of MuniHoldings Pennsylvania, in exchange solely for an equal
aggregate value of MuniYield Pennsylvania Common Shares and MuniYield
Pennsylvania Series B AMPS to be issued by MuniYield Pennsylvania and (iii)
MuniYield Pennsylvania will become subject to the requirement that under
normal circumstances, at least 80% of its assets will be invested in municipal
obligations with remaining maturities of one year or more that are covered by
insurance guaranteeing the timely payment of principal at maturity and
interest, and will change its name to "MuniYield Pennsylvania Insured Fund."
The number of MuniYield Pennsylvania Common Shares issued to each Acquired
Fund will have an aggregate net asset value equal to the aggregate net asset
value of the Common Shares of that Acquired Fund (except that cash will be
paid in lieu of any fractional shares), and the number of shares of MuniYield
Pennsylvania Series B AMPS issued to each Acquired Fund, will have an
aggregate liquidation preference and value equal to the aggregate liquidation
preference and value of each such Fund's AMPS. Upon receipt by the Acquired
Funds of such shares, the Acquired Funds will (i) distribute the MuniYield
Pennsylvania Common Shares to the holders of Common Shares of MuniVest
Pennsylvania, and MuniHoldings Pennsylvania, as applicable, in exchange for
their Common Shares in the Acquired Funds and (ii) distribute the MuniYield
Pennsylvania Series B AMPS to the holders of MuniVest Pennsylvania AMPS and to
the holders of MuniHoldings Pennsylvania Series A AMPS, in exchange for their
AMPS in the Acquired Funds. MuniYield Pennsylvania will file with the Office
of the Secretary of State of The Commonwealth of Massachusetts a Certificate
of Designation of MuniYield Pennsylvania, establishing the powers, rights and
preferences of the MuniYield Pennsylvania Series B AMPS prior to the closing
of the Reorganization. As soon as practicable after the date that the
Reorganization takes place (the "Exchange Date"), each of the Acquired

                                      54


Funds will execute and lodge among the records of the respective Acquired Fund
an instrument in writing setting forth the fact of the Fund's termination and
cause a copy to be filed in the Office of the Secretary of State of The
Commonwealth of Massachusetts.

  Each of the Acquired Funds will distribute MuniYield Pennsylvania Common
Shares and the MuniYield Pennsylvania Series B AMPS pro rata to its holders of
record of Common Shares and AMPS, as applicable, in exchange for such
shareholders' shares in the Acquired Funds. Such distribution would be
accomplished by opening new accounts on the books of MuniYield Pennsylvania in
the names of the holders of Common Shares and AMPS of each of the Acquired
Funds and transferring to those shareholder accounts the MuniYield
Pennsylvania Common Shares or MuniYield Pennsylvania Series B AMPS previously
credited on those books to the accounts of the Acquired Funds. Each newly-
opened account on the books of MuniYield Pennsylvania for the previous holders
of Common Shares of the Acquired Funds would represent the respective pro rata
number of MuniYield Pennsylvania Common Shares (rounded down, in the case of
fractional shares, to the next largest number of whole shares) due such holder
of Common Shares. No fractional MuniYield Pennsylvania Common Shares will be
issued. In lieu thereof, MuniYield Pennsylvania's transfer agent, State Street
Bank and Trust Company, will aggregate all fractional MuniYield Pennsylvania
Common Shares and sell the resulting whole shares on the NYSE for the account
of all holders of fractional interests, and each such holder will be entitled
to the pro rata share of the proceeds from such sale upon surrender of the
share certificates of the applicable Acquired Fund. Similarly, each newly-
opened account on the books of MuniYield Pennsylvania for the previous holders
of AMPS of an Acquired Fund would represent the respective pro rata number of
MuniYield Pennsylvania Series B AMPS due such holder of AMPS. See "Surrender
and Exchange of Share Certificates" below for a description of the procedures
to be followed by the shareholders of the Acquired Funds to obtain their
MuniYield Pennsylvania Common Shares and cash in lieu of fractional shares, if
any. Because AMPS are held in "street name" by The Depository Trust Company,
all transfers are accomplished by book entry and no surrender of share
certificates representing AMPS is necessary.

  Accordingly, as a result of the Reorganization, every holder of Common
Shares of an Acquired Fund would own MuniYield Pennsylvania Common Shares that
(except for cash payments received in lieu of fractional shares) would have an
aggregate net asset value immediately after the Exchange Date equal to the
aggregate net asset value of that shareholder's Common Shares immediately
prior to the Exchange Date. Since the MuniYield Pennsylvania Common Shares
would be issued at net asset value and the Common Shares of the Acquired Fund
would be valued at net asset value for the purposes of the exchange, the
holders of Common Shares of each of the Funds will not be diluted as a result
of the Reorganization. Similarly, since the MuniYield Pennsylvania Series B
AMPS would be issued at a liquidation preference and value per share equal to
the liquidation preference and value per share of the AMPS of the Acquired
Funds, holders of AMPS of each of the Funds will not be diluted as a result of
the Reorganization. However, as a result of the Reorganization, a shareholder
of any of the Funds likely will hold a reduced percentage of ownership in the
larger combined entity than he or she did in any of the constituent Funds.

Procedure

  At meetings of the Boards of Trustees of each of the Acquired Funds, and at
a meeting of the Board of Trustees of MuniYield Pennsylvania, the Board of
Trustees of each of the Funds, including all of the Trustees who are not
"interested persons," as defined in the Investment Company Act, of the
applicable Fund, approved the Agreement and Plan of Reorganization and the
submission of such Agreement and Plan of Reorganization to the shareholders of
each of the Funds for approval. The Board of Trustees of MuniVest Pennsylvania
and MuniHoldings Pennsylvania voted unanimously to approve the Reorganization
and the Board of Trustees of MuniYield Pennsylvania approved the
Reorganization by the affirmative vote of all the Trustees present at the
meeting, representing more than two-thirds of the total number of Trustees.

  The Board of Trustees of MuniYield Pennsylvania approved the filing of a
Certificate of Designation establishing the powers, rights and preferences of
the MuniYield Pennsylvania Series B AMPS in order that they may be distributed
to holders of AMPS of each of the Acquired Funds as part of the
Reorganization. The Board of MuniYield Pennsylvania, in approving the
Reorganization, also approved the change in the investment policies of that
Fund to provide that the Fund will invest at least 80% of its assets in
municipal obligations either

                                      55



(i) insured under an insurance policy purchased by the Fund or (ii) insured
under an insurance policy obtained by the issuer thereof or any other party,
as well as the change in the name of the Fund to "MuniYield Pennsylvania
Insured Fund."

  As a result of such Board approvals, the Funds have jointly filed this proxy
statement with the SEC soliciting a vote of the shareholders of each of the
Funds to approve the Reorganization. The costs of such solicitation are to be
paid by MuniYield Pennsylvania after the Reorganization so as to be borne
equally and exclusively on a per share basis by the holders of Common Shares
of each of the Funds. The special and annual meetings of shareholders of the
Funds will be held on December 15, 1999. If the shareholders of all three
Funds approve the Reorganization, the Reorganization will take place as soon
as practicable after such approval, provided that the Funds have obtained
prior to that time a favorable private letter ruling from the IRS concerning
the tax consequences of the Reorganization as set forth in the Agreement and
Plan of Reorganization or an opinion of counsel to the same effect.

  The Boards of Trustees of MuniYield Pennsylvania, MuniVest Pennsylvania and
MuniHoldings Pennsylvania recommend that the shareholders of the respective
Funds approve the Agreement and Plan of Reorganization.

Terms of the Agreement and Plan of Reorganization

  The following is a summary of the significant terms of the Agreement and
Plan of Reorganization. This summary is qualified in its entirety by reference
to the Agreement and Plan of Reorganization, attached hereto as Exhibit II.

  Valuation of Assets and Liabilities. The respective assets of each of the
Funds will be valued on the business day prior to the Exchange Date (the
"Valuation Date"). The valuation procedures are the same for all three Funds:
net asset value per share of the Common Shares of each Fund will be determined
after the close of business on the NYSE (generally, 4:00 P.M., Eastern time)
on the Valuation Date. For the purpose of determining the net asset value of a
common share of beneficial interest of each Fund, the value of the securities
held by the issuing Fund plus any cash or other assets (including interest
accrued but not yet received) minus all liabilities (including accrued
expenses) and the aggregate liquidation value of the outstanding AMPS of the
issuing Fund is divided by the total number of Common Shares of the issuing
Fund outstanding at such time. Daily expenses, including the fees payable to
FAM, will accrue on the Valuation Date.

  The Pennsylvania Municipal Bonds and Municipal Bonds in which each Fund
invests are traded primarily in the over-the-counter markets. In determining
net asset value on the Valuation Date, each Fund will use the valuations of
portfolio securities furnished by a pricing service approved by the Boards of
Trustees of the Funds. The pricing service typically values portfolio
securities at the bid price or the yield equivalent when quotations are
readily available. Pennsylvania Municipal Bonds and Municipal Bonds for which
quotations are not readily available will be valued at fair market value on a
consistent basis as determined by the pricing service using a matrix system to
determine valuations. The Boards of Trustees of the Funds have determined in
good faith that the use of a pricing service is a fair method of determining
the valuation of portfolio securities. Positions in financial futures
contracts will be valued on the Valuation Date at closing prices for such
contracts established by the exchange on which they are traded, or if market
quotations are not readily available, will be valued at fair value on a
consistent basis using methods determined in good faith by the Board of
Trustees.

  Distribution of MuniYield Pennsylvania Common Shares and MuniYield
Pennsylvania Series B AMPS. On the Exchange Date, MuniYield Pennsylvania will
issue to each Acquired Fund a number of MuniYield Pennsylvania Common Shares
the aggregate net asset value of which will equal the respective aggregate net
asset value of Common Shares of the Acquired Fund on the Valuation Date. Each
holder of Common Shares of an Acquired Fund will receive the number of
MuniYield Pennsylvania Common Shares corresponding to his or her proportionate
interest in the respective aggregate net asset value of the Common Shares of
the Acquired Fund, as applicable.

                                      56



  On the Exchange Date, MuniYield Pennsylvania also will issue (i) to MuniVest
Pennsylvania a number of MuniYield Pennsylvania Series B AMPS, the aggregate
liquidation preference and value of which will equal the aggregate liquidation
preference and value of MuniVest Pennsylvania AMPS on the Valuation Date and
(ii) to MuniHoldings Pennsylvania a number of MuniYield Pennsylvania Series B
AMPS, the aggregate liquidation preference and value of which will equal the
aggregate liquidation preference and value of MuniHoldings Pennsylvania Series
A AMPS on the Valuation Date. Each holder of AMPS of an Acquired Fund will
receive the number of MuniYield Pennsylvania Series B AMPS, corresponding to
his or her proportionate interest in the aggregate liquidation preference and
value of the AMPS of the Acquired Fund. No sales charge or fee of any kind
will be charged to shareholders of the Acquired Funds in connection with their
receipt of MuniYield Pennsylvania Common Shares or AMPS in the Reorganization.
Holders of MuniHoldings Pennsylvania AMPS will find that the auction date and
dividend payment date for the MuniYield Pennsylvania Series B AMPS received in
the Reorganization fall on different days of the week than the auction date
and dividend payment date of the AMPS currently held. Any such change in the
auction date and dividend payment date will not adversely affect the value of
a holder's AMPS. It is anticipated that the auction for MuniYield Pennsylvania
Series B AMPS will be held on Tuesday; MuniVest Pennsylvania Series A AMPS are
auctioned on Tuesday, but MuniHoldings Pennsylvania Series A AMPS are
auctioned on Friday. The auction procedures for all of the AMPS are
substantially the same. As a result of the Reorganization, the last dividend
period for the AMPS of each Acquired Fund prior to the Exchange Date may be
shorter than the dividend period for such AMPS determined as set forth in the
applicable Certificate of Designation.

  Expenses. MuniYield Pennsylvania shall pay, subsequent to the Exchange Date,
all expenses incurred in connection with the Reorganization, including, but
not limited to, all costs related to the preparation and distribution of
materials distributed to each Fund's Board of Trustees, expenses incurred in
connection with the preparation of the Agreement and Plan of Reorganization, a
registration statement on Form N-14 and a private letter ruling request
submitted to the IRS, SEC and state securities commission filing fees and
legal and audit fees in connection with the Reorganization, costs of printing
and distributing this Proxy Statement and Prospectus, legal fees incurred
preparing each Fund's board materials, attending each Fund's board meetings
and preparing the minutes, accounting fees associated with each Fund's
financial statements, stock exchange fees, rating agency fees, portfolio
transfer taxes (if any) and any similar expenses incurred in connection with
the Reorganization. In this regard, expenses of the Reorganization will be
deducted from the assets of the combined fund so as to be borne equally and
exclusively on a per share basis by the holders of Common Shares of each of
the Funds. No Fund shall pay any expenses of its respective shareholders
arising out of or in connection with the Reorganization.

  Required Approvals. Under the Declaration of Trust of each Fund (as amended
to date and including Certificates of Designation establishing the powers,
rights and preferences of the AMPS of each Fund), relevant Massachusetts law
and the rules of the NYSE and AMEX, shareholder approval of the Agreement and
Plan of Reorganization requires the affirmative vote of shareholders
representing more than 50% of the outstanding Common Shares and AMPS, voting
together as a single class, and more than 50% of the AMPS, voting separately
as a class. Because of the requirement that the Agreement and Plan of
Reorganization be approved by the shareholders of all three Funds, the
Reorganization will not take place if the shareholders of any one Fund do not
approve the Agreement and Plan of Reorganization.

  Deregistration and Termination. Following the transfer of the assets and
liabilities of the Acquired Funds and the distribution of MuniYield
Pennsylvania Common Shares and MuniYield Pennsylvania Series B AMPS to
shareholders of the Acquired Funds, in accordance with the foregoing, each of
the Acquired Funds will terminate its registration under the Investment
Company Act and its organization under Massachusetts law and will withdraw its
authority to do business in any state where it is required to do so.

  Amendments and Conditions. The Agreement and Plan of Reorganization may be
amended at any time prior to the Exchange Date with respect to any of the
terms therein. The obligations of each Fund pursuant to the Agreement and Plan
of Reorganization are subject to various conditions, including a registration
statement on Form N-14 being declared effective by the Commission, approval by
the shareholders of each of the Funds,

                                      57


favorable IRS rulings or an opinion of counsel being received as to tax
matters, an opinion of counsel as to securities matters being received and the
continuing accuracy of various representations and warranties of the Funds
being confirmed by the respective parties.

  Postponement, Termination. Under the Agreement and Plan of Reorganization,
the Board of Trustees of any of the Funds may cause the Reorganization to be
postponed or abandoned under certain circumstances should such Board determine
that it is in the best interests of the shareholders of its respective Fund to
do so. The Agreement and Plan of Reorganization may be terminated, and the
Reorganization abandoned at any time (whether before or after adoption thereof
by the shareholders of any of the Funds) prior to the Exchange Date, or the
Exchange Date may be postponed: (i) by mutual consent of the Boards of
Trustees of the three Funds and (ii) by the Board of Trustees of any Fund if
any condition to that Fund's obligations set forth in the Agreement and Plan
of Reorganization has not been fulfilled or waived by such Board.

Potential Benefits to Holders of Common Shares of the Funds as a Result of the
Reorganization

  In approving the Reorganization, the Board of Trustees of each Fund
identified certain benefits that are likely to result from the Reorganization,
including lower aggregate operating expenses per share of Common Shares,
greater efficiency and flexibility in portfolio management and a more liquid
trading market for the Common Shares of the combined fund. With respect to
each of the Acquired Funds, following the Reorganization their respective
shareholders will remain invested in a closed-end fund that has investment
objectives and policies substantially similar to those of the Acquired Fund.
The Boards also considered the possible risks and costs of combining the
Funds, and examined the relative credit strength, maturity characteristics,
mix of type and purpose, and yield of the Funds' portfolios of Pennsylvania
Municipal Bonds and Municipal Bonds and the costs involved in a transaction
such as the Reorganization. The Boards noted the many similarities between the
Funds, including their substantially similar investment objectives and
investment policies, their use of substantially the same management personnel
and their similar portfolios of Pennsylvania Municipal Bonds and Municipal
Bonds. The Boards also considered the relative tax positions of each of the
Fund's portfolios. Based on these factors, the Boards concluded that the
Reorganization will potentially benefit the shareholders of each Fund in that
it (i) presents no significant risks that would outweigh the benefits
discussed herein above and (ii) involves minimal costs (including relatively
minor legal, accounting and administrative costs). MuniYield Pennsylvania's
Board also considered the possible risks and costs to MuniYield Pennsylvania
of becoming an insured fund and concluded that based on current portfolio
holdings and market conditions the risks were minimal.

  The surviving fund that would result from the Reorganization would have a
larger asset base than any of the Funds has currently. Based on data presented
by FAM, the Board of each Fund believes that administrative expenses for a
larger combined fund would be less than the aggregate expenses for the
individual Funds, resulting in a lower expense ratio for common shareholders
of the combined fund and higher earnings per common share. In particular,
certain fixed costs, such as costs of printing shareholder reports and proxy
statements, legal expenses, audit fees, mailing costs and other expenses will
be spread across a larger asset base, thereby lowering the expense ratio for
the combined fund. To illustrate the potential economies of scale, the table
below shows the total annualized operating expense ratio of each Fund and pro
forma MuniYield Pennsylvania based on net assets both excluding and including
assets attributable to AMPS as of June 30, 1999:

                                      58


  Management projections estimate that MuniYield Pennsylvania will have net
assets in excess of $256.6 million including assets attributable to AMPS upon
completion of the Reorganization. A larger asset base should provide benefits
in portfolio management. After the Reorganization, MuniYield Pennsylvania
should be able to purchase larger amounts of Pennsylvania Municipal Bonds and
Municipal Bonds at more favorable prices than any of the Funds separately and,
with this greater purchasing power, request improvements in the terms of the
Pennsylvania Municipal Bonds and Municipal Bonds (e.g., added indenture
provisions covering call protection, sinking funds and audits for the benefit
of large holders) prior to purchase.

  Based on the foregoing, the Boards concluded that the Reorganization is in
the best interests of the shareholders of each of the Funds because the
Reorganization presents no significant risks or costs (including legal,
accounting and administrative costs) that would outweigh the benefits
discussed above.

  In approving the Reorganization, the Board of Trustees of each Fund
determined that the Reorganization is in the best interests of that Fund and,
with respect to net asset value and liquidation preference, that the interests
of existing shareholders of that Fund would not be diluted as a result of the
Reorganization. Although the Reorganization is expected to result in a
reduction in net asset value per share of the combined fund after the
Reorganization of approximately $.02 as a result of the estimated costs of the
Reorganization, management of each Fund advised its Board that it expects that
such costs would be recovered within six months to 3 1/2 years after the
Exchange Date due to a decrease in the operating expense ratio.

  It is not anticipated that the Reorganization directly would benefit the
holders of AMPS of any of the Funds; however, the Reorganization will not
adversely affect the holders of AMPS of any of the Funds and the expenses of
the Reorganization will not be borne by the holders of AMPS of any of the
Funds.

Surrender and Exchange of Share Certificates

  After the Exchange Date, each holder of an outstanding certificate or
certificates formerly representing Common Shares of any one of the Acquired
Funds will be entitled to receive, upon surrender of his or her certificate or
certificates, a certificate or certificates representing the number of
MuniYield Pennsylvania Common Shares distributable with respect to such
holder's Common Shares of the Acquired Fund, together with cash in lieu of any
fractional shares of beneficial interest. Promptly after the Exchange Date,
the transfer agent for the MuniYield Pennsylvania Common Shares will mail to
each holder of certificates formerly representing Common Shares of an Acquired
Fund a letter of transmittal for use in surrendering his or her certificates
for certificates representing MuniYield Pennsylvania Common Shares and cash in
lieu of any fractional Common Shares.

  Shares of AMPS are held in "street name" by the Depository Trust Company,
and all transfers will be accomplished by book entry. Surrender of physical
certificates for AMPS is not required.

  Please do not send in any share certificates at this time. Upon consummation
of the Reorganization, holders of Common Shares of the Acquired Funds will be
furnished with instructions for exchanging their share certificates for
MuniYield Pennsylvania share certificates and, if applicable, cash in lieu of
fractional shares.

  From and after the Exchange Date, certificates formerly representing Common
Shares of an Acquired Fund will be deemed for all purposes to evidence
ownership of the number of full shares of MuniYield Pennsylvania Common Shares
distributable with respect to the Common Shares of the Acquired Fund held
before the

Reorganization as described above and as shown in the table above, provided
that, until such share certificates have been so surrendered, no dividends
payable to the holders of record of Common Shares of an Acquired Fund as of
any date subsequent to the Exchange Date will be paid to the holders of such
outstanding share certificates. Dividends payable to holders of record of
Common Shares of MuniYield Pennsylvania, as of any date after the Exchange
Date and prior to the exchange of certificates by any shareholder of an
Acquired Fund, will be paid to such shareholder, without interest, at the time
such shareholder surrenders his or her share certificates for exchange.

  From and after the Exchange Date, there will be no transfers on the stock
transfer books of any Acquired Fund. If, after the Exchange Date, certificates
representing Common Shares of an Acquired Fund are presented to MuniYield
Pennsylvania, they will be canceled and exchanged for certificates
representing Common Shares of MuniYield Pennsylvania, as applicable, and cash
in lieu of fractional Common Shares of MuniYield Pennsylvania, if any,
distributable with respect to such Common Shares in the Reorganization.

Tax Consequences of the Reorganization

  General. The Reorganization has been structured with the intention that it
qualify for Federal income tax purposes as a tax-free reorganization under
Section 368(a)(1)(C) of the Code. Each of the three Funds has elected and
qualified for the special tax treatment afforded RICs under the Code, and
MuniYield Pennsylvania intends to continue to so qualify after the
Reorganization. The Funds have jointly requested a private letter ruling from
the IRS that for Federal income tax purposes: (i) the exchange of assets by
each Acquired Fund for MuniYield Pennsylvania shares, as described, will
constitute a reorganization within the meaning of Section 361(a)(1)(C) of the
Code, and each of the Acquired Funds and MuniYield Pennsylvania will be deemed
a "party" to a reorganization within the meaning of Section 368(b) of the
Code; (ii) in accordance with Section 368(a) of the Code, no gain or loss will
be recognized to the Acquired Funds as a result of the Reorganization or on
the distribution of MuniYield Pennsylvania Common Shares and MuniYield
Pennsylvania Series B AMPS, to the respective shareholders of the Acquired
Funds under Section 361(c)(1) of the Code; (iii) under Section 1032 of the
Code, no gain or loss will be recognized to MuniYield Pennsylvania as a result
of the Reorganization; (iv) in accordance with Section 354(a)(1) of the Code,
no gain or loss will be recognized to the shareholders of the Acquired Funds
on the receipt of MuniYield Pennsylvania Common Shares and MuniYield
Pennsylvania Series B AMPS in exchange for their corresponding Common Shares
or AMPS of an Acquired Fund (except to the extent that holders of Common
Shares receive cash representing an interest in fractional Common Shares of
MuniYield Pennsylvania in the Reorganization); (v) in accordance with Section
362(b) of the Code, the tax basis of the assets of the Acquired Funds in the
hands of MuniYield Pennsylvania will be the same as the tax basis of such
assets in the hands of the Acquired Fund that transferred them immediately
prior to the consummation of the Reorganization; (vi) in accordance with
Section 358 of the Code, immediately after the Reorganization, the tax basis
of the MuniYield Pennsylvania Common Shares and MuniYield Pennsylvania Series
B AMPS received by the shareholders of the Acquired Funds in the
Reorganization will be equal to the tax basis of the Common Shares or AMPS of
the Acquired Funds surrendered in exchange; (vii) in accordance with Section
1223 of the Code, a shareholder's holding period for the MuniYield
Pennsylvania Common Shares and MuniYield Pennsylvania Series B AMPS, will be
determined by including the period for which such shareholder held the Common
Shares or AMPS of the Acquired Fund exchanged therefor, provided that such
shares were held as a capital asset; (viii) in accordance with Section 1223 of
the Code, MuniYield Pennsylvania's holding period with respect to the assets
of the Acquired Funds transferred will include the period for which such
assets were held by the Acquired Fund; (ix) the payment of cash to holders of
Common Shares of an Acquired Fund in lieu of fractional MuniYield Pennsylvania
Common Shares will be treated as though the fractional shares were distributed
as part of the Reorganization and then redeemed, with the result that such
shareholders will have short- or long-term capital gain or loss to the extent
that the cash distribution differs from the shareholder's basis allocable to
the MuniYield Pennsylvania fractional shares; and (x) the taxable year of each
of the Acquired Funds will end on the effective date of the Reorganization and
pursuant to Section 381(a) of the Code and regulations thereunder, MuniYield
Pennsylvania will succeed to and take into account certain tax attributes of
the Acquired Funds, such as earnings and profits, capital loss carryovers and
method of accounting.

                                      60



  As noted in the discussion under "Comparison of the Funds--Tax Rules
Applicable to the Funds and Their Shareholders," a Fund must distribute
annually at least 90% of its net taxable and tax-exempt income. A distribution
will only be counted for this purpose if it qualifies for the dividends paid
deduction under the Code. In the opinion of Brown & Wood LLP, the issuance of
MuniYield Pennsylvania Series B AMPS pursuant to the Reorganization in
addition to the already existing preferred shares of MuniYield Pennsylvania
(to be redesignated MuniYield Pennsylvania Series A AMPS) will not cause
distributions on any series of MuniYield Pennsylvania AMPS to be treated as
preferential dividends ineligible for the dividends paid deduction. It is
possible, however, that the IRS may assert that, because there is more than
one series of AMPS, distributions on such shares are preferential under the
Code and therefore not eligible for the dividends paid deduction. If the IRS
successfully disallowed the dividends paid deduction for dividends on the
AMPS, MuniYield Pennsylvania could lose the special tax treatment afforded
RICs. In this case, dividends on the MuniYield Pennsylvania Common Shares and
AMPS would not be exempt from Federal income tax. Additionally, MuniYield
Pennsylvania would be subject to the Federal alternative minimum tax.

  Under Section 381(a) of the Code, MuniYield Pennsylvania will succeed to and
take into account certain tax attributes of the Acquired Funds, including, but
not limited to, earnings and profits, any net operating loss carryovers, any
capital loss carryovers and method of accounting. The Code, however, contains
special limitations with regard to the use of net operating losses, capital
losses and other similar items in the context of certain reorganizations,
including tax-free reorganizations pursuant to Section 368(a)(1)(C) of the
Code, which could reduce the benefit of these attributes to MuniYield
Pennsylvania.

  Shareholders should consult their tax advisers regarding the effect of the
Reorganization in light of their individual circumstances. As the foregoing
relates only to Federal income tax consequences, shareholders also should
consult their tax advisers as to the foreign, state and local tax consequences
of the Reorganization.

  Regulated Investment Company Status. The Funds have elected and qualified
for taxation as RICs under Sections 851-855 of the Code, and after the
Reorganization MuniYield Pennsylvania intends to continue to so qualify.

Appraisal Rights

  A shareholder of any of the Funds who does not vote in favor of the
Reorganization may have the right under Massachusetts law to object to the
Reorganization and demand payment for his or her shares from the applicable
Fund and an appraisal thereof upon compliance with the procedures specified in
Sections 86 through 98 of the Massachusetts Business Corporation Law (the
"Massachusetts Business Corporation Law"), which are set forth in Exhibit VI
hereto. A vote against the Reorganization or the execution of a proxy
directing such a vote will not satisfy the requirements of those provisions. A
failure to vote against the Reorganization will not constitute a waiver of
such rights. The Funds take the position that, if available, this statutory
right of appraisal may be exercised only by shareholders of record.

  Section 92 of the Massachusetts Business Corporation Law provides that for
purposes of payment to any shareholder who elects to exercise his or her
statutory right of appraisal, the value of shares of such shareholder is to be
determined as of the day preceding the date of the shareholders' vote
approving the Agreement and Plan of Reorganization. Under the terms of the
Agreement and Plan of Reorganization, MuniYield Pennsylvania will assume the
obligations of each of the Funds, if any, with respect to statutory rights of
appraisal.

  For federal income tax purposes, dissenting shareholders obtaining payment
for their shares will recognize gain or loss measured by the difference
between any such payment and the tax basis for their shares. Shareholders are
advised to consult their personal tax advisers as to the tax consequences of
dissenting.

                         ITEM 2. ELECTION OF TRUSTEES

  At the annual meeting of MuniHoldings Pennsylvania, the Board of Trustees
for MuniHoldings Pennsylvania will be elected to serve until the next annual
meeting of shareholders and until their successors are elected and qualified.
If the shareholders of all of the Funds approve the Reorganization, then the
current Board of Trustees of MuniYield Pennsylvania will serve as the Board of
the combined fund, until its next annual meeting of shareholders. If the
shareholders of any Fund vote against the Reorganization, then the Board of
Trustees elected at the annual meeting of MuniHoldings Pennsylvania will
continue to serve until the next annual meeting of shareholders of
MuniHoldings Pennsylvania and the current Board of MuniYield Pennsylvania and
MuniVest Pennsylvania will continue to serve until the next annual meeting of
that Fund. 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 of MuniHoldings Pennsylvania,
  voting separately as a class, will be voted in favor of the two persons
  designated as Trustees to be elected by the holders of AMPS of MuniHoldings
  Pennsylvania; and

    (2) All proxies of the holders of Common Shares and AMPS of MuniHoldings
  Pennsylvania, voting together as a single class, will be voted in favor of
  the five persons designated as Trustees to be elected by the holders of
  Common Shares and AMPS of MuniHoldings Pennsylvania.

  The Board of Trustees of MuniHoldings Pennsylvania 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 appropriate Board of Trustees may recommend.

  Certain information concerning the nominees is set forth below. Additional
information concerning the nominees and other information relevant to the
election of Trustees is set forth in Exhibit I.

    of one or more additional investment companies for which FAM, MLAM or their

 * Interested person, as defined in the Investment Company Act, of each of the
   Funds.

                                       64


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 Audit Committee also reviews and nominates
candidates to serve as non-interested Board members. The non-interested Board
members have retained independent legal counsel to assist them in connection
with these duties.

  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 or she
served. See Exhibit I for further information about Audit Committee and Board
meetings.

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 Trustees 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 SEC and the NYSE or the AMEX, as applicable. Officers,
trustees and greater than ten percent shareholders 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, trustees, 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.

Interested Persons

  Each Fund considers Mr. Zeikel and Mr. Glenn to be "interested persons" of
the Fund within the meaning of Section 2(a)(19) of the Investment Company Act
because of the positions each holds or has held with FAM and its affiliates.
Mr. Glenn is the President of each Fund.

Compensation of Trustees

  FAM, the investment adviser of each Fund, pays all compensation to all
officers of each Fund and all Trustees of each Fund who are affiliated with ML
& Co. or its subsidiaries. Each Fund pays each Trustee not affiliated with FAM
(each a "non-affiliated Trustee") 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 Trustees, an annual fee plus a fee for
each meeting attended, together with such Trustee's out-of-pocket expenses
relating to attendance at such meetings. Information with respect to fees and
expenses paid to the non-affiliated Trustees for each Fund's most recently
completed fiscal year is set forth in Exhibit I.

Officers of MuniHoldings Pennsylvania

  Information regarding the officers of MuniHoldings Pennsylvania is set forth
in Exhibit I. 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.


                                      65


                   ITEM 3. SELECTION OF INDEPENDENT AUDITORS

  The Board of Trustees of MuniHoldings Pennsylvania, including a majority of
the Trustees who are not interested persons of the Fund, has selected Deloitte
& Touche LLP ("D&T") as the independent auditors to audit the financial
statements of the Fund for the Fund's current fiscal year. The current fiscal
year for MuniHoldings Pennsylvania is the fiscal year ending September 30,
2000. The Fund knows of no direct or indirect financial interest of such
auditors in the Fund. Such appointment is subject to ratification or rejection
by the shareholders of MuniHoldings Pennsylvania.

  D&T also acts as independent auditors for ML & Co. and most of its
subsidiaries, including FAM and MLAM, and for most other investment companies
for which FAM or MLAM acts as investment adviser. The Board of Trustees of
MuniHoldings Pennsylvania considered the fact that D&T have been retained as
the independent auditors for ML & Co. and the other entities described above
in its evaluation of the independence of D&T with respect to the Fund.

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

INFORMATION CONCERNING THE ANNUAL MEETING OF MUNIHOLDINGS PENNSYLVANIA AND THE
     SPECIAL MEETINGS OF MUNIYIELD PENNSYLVANIA AND MUNIVEST PENNSYLVANIA

Date, Time and Place of Meetings

  The Meetings will be held on December 15, 1999 at the offices of MLAM, 800
Scudders Mill Road, Plainsboro, New Jersey at the times listed on Exhibit I.

Solicitation, Revocation and Use of Proxies

  A shareholder executing and returning a proxy has the power to revoke it at
any time prior to its exercise by executing a superseding proxy, by giving
written notice of the revocation to the Secretary of the appropriate Fund or
by voting in person at the Meeting. Although mere attendance at the Meetings
will not revoke a proxy, a shareholder present at the Meetings may withdraw
his or her proxy and vote in person.

  All shares represented by properly executed proxies, unless such proxies
previously have 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" (i) the approval of the Agreement and Plan of Reorganization
and, for the shareholders of MuniHoldings Pennsylvania only, "FOR" (ii) the
election of the nominees to the Board of Trustees and (iii) the ratification
of the selection of D&T or as independent auditors of MuniHoldings
Pennsylvania. It is not anticipated that any other matters will be brought
before the Meetings. If, however, any other business properly is brought
before the Meetings, proxies will be voted in accordance with the judgment of
the persons designated on such proxies.

Record Date and Outstanding Shares

  Only holders of record of Common Shares or AMPS of any of the Funds at the
close of business on the Record Date are entitled to vote at the Meetings or
any adjournment thereof. At the close of business on the Record Date, the
Funds had the number of shares outstanding indicated in Exhibit I.

                                      66


Security Ownership of Certain Beneficial Owners and Management

  To the knowledge of the Funds, at the date hereof, no person or entity owns
beneficially 5% or more of the Common Shares or AMPS of any Fund.

  As of the Record Date, none of the nominees for Trustee of MuniHoldings
Pennsylvania or the Trustees of MuniYield Pennsylvania or MuniVest
Pennsylvania held shares of the Funds except as set forth in the table below:



      Nominee              Fund and Class of Shares         No. of Shares Held*
      -------       --------------------------------------- -------------------
                                                      
Terry K. Glenn.....   MuniVest Pennsylvania Common Shares         25,518
                    MuniHoldings Pennsylvania Common Shares       13,724

- --------

* These holdings represent less than 1% of the Common Shares outstanding of
  the relevant Fund.

  As of the Record Date, the Trustees and officers of MuniYield Pennsylvania
as a group (12 persons) owned an aggregate of less than 1% of the outstanding
Common Shares of MuniYield Pennsylvania and owned no MuniYield Pennsylvania
AMPS.

  As of the Record Date, the Trustees and officers of MuniVest Pennsylvania as
a group (13 persons) owned an aggregate of less than 1% of the outstanding
Common Shares of MuniVest Pennsylvania and owned no MuniVest Pennsylvania
AMPS.

  As of the Record Date, the Trustees and officers of MuniHoldings
Pennsylvania as a group (12 persons) owned an aggregate of less than 1% of the

Funds, Mr. Zeikel, a Trustee of each of the Funds, and the other Trustees and
officers of each Fund owned an aggregate of less than 1% of the outstanding
shares of common stock of ML & Co.

Voting Rights and Required Vote

  For purposes of this Proxy Statement and Prospectus, holders of Common
Shares and AMPS of each of the Funds are entitled to one vote for each share
held. Approval of the Agreement and Plan of Reorganization requires the
approval of each Fund. With respect to each Fund, approval of the Agreement
and Plan of Reorganization requires the affirmative vote of shareholders
representing (i) a majority of the Fund's outstanding Common Shares and AMPS,
voting together as a single class, and (ii) a majority of the Fund's
outstanding AMPS, voting separately as a class. See "Agreement and Plan of
Reorganization--Appraisal Rights" and Exhibit VI--"Sections 86 through 98 of
Chapter 156B of the Massachusetts General Laws (the Massachusetts Business
Corporation Law)" for a discussion of dissenters' rights under Massachusetts
law.

  For purposes of each Meeting, a quorum consists of a majority of the
outstanding shares of each Fund, present in person or by proxy. If, by the
time scheduled for each Meeting, a quorum of the applicable Fund's
shareholders is not present, or if a quorum is present but sufficient votes to
approve or disapprove the Agreement and Plan of Reorganization are not
received from the shareholders of the applicable Fund, the persons named as
proxies may propose one or more adjournments of the Meeting to permit further
solicitation of proxies from shareholders. Any such adjournment will require
the affirmative vote of a majority of the shares of the applicable Fund
present in person or by proxy and entitled to vote at the session of the
Meeting to be adjourned. The persons named as proxies will vote in favor of
any such adjournment if they determine that adjournment and additional
solicitation are reasonable and in the interests of the applicable Fund's
shareholders.

  With respect to the election of Trustees of MuniHoldings Pennsylvania,
assuming a quorum is present, holders of MuniHoldings Pennsylvania AMPS,
voting separately as a class, are entitled to elect two Trustees of the Fund
and holders of the Fund's Common Shares and AMPS, voting together as a single
class, are entitled to

                                      67


elect the remaining Trustees of that Fund. Assuming a quorum is present, (x)
election of the two Trustees of MuniHoldings Pennsylvania to be elected by the
holders of that Fund's AMPS, voting separately as a class, will require the
affirmative vote of a majority of the votes cast by the holders of that Fund's
AMPS, represented at the Meeting and entitled to vote, voting together as a
single class; and (y) election of the remaining Trustees of the Fund will
require the affirmative vote of a majority of the votes cast by the holders of
that Fund's Common Shares and AMPS, represented at the annual meeting and
entitled to vote, voting together as a single class.

  Assuming a quorum is present, approval of the ratification of the selection
of the independent auditors of MuniHoldings Pennsylvania, will require the
affirmative vote of a majority of the votes cast by the holders of Common
Shares and AMPS of MuniHoldings Pennsylvania represented at the annual meeting
and entitled to vote, voting together as a single class.

                            ADDITIONAL INFORMATION

  The expenses of preparation, printing and mailing of the enclosed form of
proxy, the accompanying Notice and this Proxy Statement and Prospectus will be
borne by MuniYield Pennsylvania, the surviving fund after the Reorganization,
so as to be borne equally and exclusively on a per share basis by the holders
of Common Shares of each of the Funds. If the Reorganization is not approved,
these expenses will be allocated among the Funds according to the net asset
value of Common Shares of each Fund on the Meeting date.

  The Funds likewise will reimburse banks, brokers and others for their
reasonable expenses in forwarding proxy solicitation materials to the
beneficial owners of shares of each of the Funds and certain persons that the
Funds may employ for their reasonable expenses in assisting in the
solicitation of proxies from such beneficial owners of capital shares of the
Funds.

  In order to obtain the necessary quorum at the Meetings, supplementary
solicitation may be made by mail, telephone, telegraph or personal interview
by officers of the Funds. Each of the Funds has retained Shareholder
Communications Corporation, 17 State Street, New York, New York 10004 to aid
in the solicitation of proxies, at a cost to be borne by each of the Funds of
approximately $7,500, plus out-of-pocket expenses.

  Broker-dealer firms, including Merrill Lynch, holding Fund shares 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
proposal before the Meetings. The Funds understand that, under the rules of
the NYSE and the AMEX, such broker-dealer firms may, without instructions from
their customers and clients, grant authority to the proxies designated to vote
on the election of the Trustees of each Fund (Item 2) and the ratification of
the selection of independent auditors for each Fund (Item 3) if no
instructions have been received prior to the date specified in the broker-
dealer firm's request for voting instructions. With respect to Common Shares
of each Fund, broker-dealer firms, including Merrill Lynch, will not be
permitted to grant voting authority without instructions with respect to the
approval of the Agreement and Plan of Reorganization (Item 1). AMPS of a Fund
held in "street name," however, may be voted without instructions under
certain conditions by broker-dealer firms with respect to Item 1 and counted
for purposes of establishing a quorum of that Fund if no instructions are
received one business day before the Meeting or, if adjourned, one business
day before the day to which the Meeting is adjourned. With respect to each
Fund, these conditions include, among others, that (i) at least 30% of that
Fund's AMPS outstanding have voted on Item 1, (ii) less than 10% of that
Fund's AMPS outstanding have voted against Item 1 and (iii) holders of that
Fund's Common Shares have voted to approve Item 1. In such instances, the
broker-dealer firm will vote that Fund's AMPS on Item 1 in the same proportion
as the votes cast by all holders of that Fund's AMPS who voted on Item 1. The
Funds will include shares held of record by broker-dealers as to which such
authority has been granted in its tabulation of the total number of shares
present for purposes of determining whether the necessary quorum of
shareholders of each Fund exists. Proxies that are returned to a Fund but that
are marked "abstain" or on which a broker-dealer has declined to vote on any
Item ("broker non-votes") will be counted as present for the purposes of
determining a quorum. Merrill Lynch has advised the Funds 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 2 and 3 (with respect to
Common Shares and AMPS) and on Item 1 (with respect to AMPS only) in the same
proportion as the votes received from beneficial owners of those shares for

                                      68


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 Items 2 and 3. Abstentions and broker non-votes will have the same
effect as a vote against Item 1.

  This Proxy Statement and Prospectus does not contain all of the information
set forth in the registration statement and the exhibits relating thereto that
MuniYield Pennsylvania has filed with the Commission under the Securities Act
and the Investment Company Act, to which reference is hereby made.

Year 2000 Issues

  Many computer systems were designed using only two digits to designate
years. These systems may not be able to distinguish the Year 2000 from the
Year 1900 (commonly known as the "Year 2000 Problem"). The Funds could be
adversely affected if the computer systems used by FAM or other service
providers of the Funds do not properly address this problem before January 1,
2000. FAM expects to have addressed this problem before then, and does not
anticipate that the services it provides will be adversely affected. The
Funds' other service providers have told FAM that they also expect to resolve
the Year 2000 Problem, and FAM will continue to monitor the situation as the
Year 2000 approaches. However, if the problem has not been fully addressed,
the Funds could be negatively affected. The Year 2000 Problem could also have
a negative impact on the issuers of securities in which the Funds invest, and
this could hurt the Funds' investment returns.

INDEPENDENT AUDITORS' REPORT

The Board of Trustees and Shareholders,
MuniYield Pennsylvania Fund:

We have audited the accompanying statement of assets, liabilities and capital,
including the schedule of investments, of MuniYield Pennsylvania Fund as of
October 31, 1998, the related statements of operations for the year then ended
and changes in net assets for each of the years in the two-year period then
ended and the financial highlights for each of the years in the five-year
period then ended. These financial statements and the financial highlights are
the responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and the financial highlights based on our
audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and the financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights. Our procedures included confirmation of
securities owned at October 31, 1998 by correspondence with the custodian and
brokers. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial position of MuniYield
Pennsylvania Fund as of October 31, 1998, the results of its operations, the
changes in its net assets, and the financial highlights for the respective
stated periods in conformity with generally accepted accounting principles.

NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

1. Significant Accounting Policies:

MuniYield Pennsylvania Fund (the "Fund") is registered under the Investment
Company Act of 1940 as a non-diversified, closed-end management investment
company. The Fund determines and makes available for publication the net asset
value of its Common Shares on a weekly basis. The Fund's Common Shares are
listed on the New York Stock Exchange under the symbol MPA. The following is a
summary of significant accounting policies followed by the Fund.

(a) Valuation of investments -- Municipal bonds are traded primarily in the
over-the-counter markets and are valued at the most recent bid price or yield
equivalent as obtained by the Fund's pricing service from dealers that make
markets in such securities. Financial futures contracts and options thereon,
which are traded on exchanges, are valued at their closing prices as of the
close of such exchanges. Options written or purchased are valued at the last
sale price in the case of exchange-traded options. In the case of options traded
in the over-the-counter market, valuation is the last asked price (options
written) or the last bid price (options purchased). Securities with remaining
maturities of sixty days or less are valued at amortized cost, which
approximates market value. Securities and assets for which market quotations are
not readily available are valued at their fair value as determined in good faith
by or under the direction of the Board of Trustees of the Fund, including
valuations furnished by a pricing service retained by the Fund, which may
utilize a matrix system for valuations. The procedures of the pricing service
and its valuations are reviewed by the officers of the Fund under the general
supervision of the Board of Trustees.

(b) Derivative financial instruments -- The Fund may engage in various portfolio
strategies to seek to increase its return by hedging its portfolio against
adverse movements in the debt markets. Losses may arise due to changes in the
value of the contract or if the counterparty does not perform under the
contract.

 . Financial futures contracts -- The Fund may purchase or sell financial futures
contracts and options on such futures contracts for the purpose of hedging the
market risk on existing securities or the intended purchase of securities.
Futures contracts are contracts for delayed delivery of securities at a specific
future date and at a specific price or yield. Upon entering into a contract, the
Fund deposits and maintains as collateral such initial margin as required by the
exchange on which the transaction is effected. Pursuant to the contract, the
Fund agrees to receive from or pay to the broker an amount of cash equal to the
daily fluctuation in value of the contract. Such receipts or payments are known
as variation margin and are recorded by the Fund as unrealized gains or losses.
When the contract is closed, the Fund records a realized gain or loss equal to
the difference between the value of the contract at the time it was opened and
the value at the time it was closed.

 . Options -- The Fund is authorized to write covered call options and purchase
put options. When the Fund writes an option, an amount equal to the premium
received by the Fund is reflected as an asset and an equivalent liability. The
amount of the liability is subsequently marked to market to reflect the current
market value of the option written.

When a security is purchased or sold through an exercise of an option, the
related premium paid (or received) is added to (or deducted from) the basis of
the security acquired or deducted from (or added to) the proceeds of the
security sold. When an option expires (or the Fund enters into a closing
transaction), the Fund realizes a gain or loss on the option to the extent of
the premiums received or paid (or gain or loss to the extent the cost of the
closing transaction exceeds the premium paid or received).

Written and purchased options are non-income producing investments.

(c) Income taxes -- It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no Federal income tax provision is required.

(d) Security transactions and investment income -- Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Interest income is recognized on the accrual basis. Discounts and market
premiums are amortized into interest income. Realized gains and losses on
security transactions are determined on the identified cost basis.

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

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

(e) Dividends and distributions -- Dividends from net investment income are
declared and paid monthly. Distributions of capital gains are recorded on the
ex-dividend dates.

(f) Reclassification -- Generally accepted accounting principles require that
certain components of net assets be adjusted to reflect permanent differences
between financial and tax reporting. Accordingly, current year's permanent
book/tax differences of $521 have been reclassified between undistributed net
realized capital gains and undistributed net investment income. These
reclassifications have no effect on net assets or net asset value per share.

2. Investment Advisory Agreement and Transactions with Affiliates:

The Fund has entered into an Investment Advisory Agreement with Fund Asset
Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc.
("PSI"), an indirect wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML &
Co."), which is the limited partner.

FAM is responsible for the management of the Fund's portfolio and provides the
necessary personnel, facilities, equipment and certain other services necessary
to the operations of the Fund. For such services, the Fund pays a monthly fee at
an annual rate of 0.50% of the Fund's average weekly net assets, including
proceeds from the issuance of Preferred Shares.

Accounting services are provided to the Fund by FAM at cost.

Certain officers and/or trustees of the Fund are officers and/or directors of
FAM, PSI, and/or ML & Co.

3. Investments:

Purchases and sales of investments, excluding short-term securities, for the
year ended October 31, 1998 were $78,090,125 and $77,069,722, respectively.

Net realized gains for the year ended October 31, 1998 and net unrealized gains

4. Beneficial Interest Transactions:

The Fund is authorized to issue an unlimited number of shares of beneficial
interest, including Preferred Shares, par value $.10 per share, all of which
were initially classified as Common Shares. The Board of Trustees is authorized,
however, to reclassify any unissued shares of beneficial interest without
approval of the holders of Common Shares.

Common Shares

Shares issued and outstanding during the year ended October 31, 1998 increased
by 49,322 as a result of dividend reinvestment and during the year ended October
31, 1997 remained constant.

Preferred Shares

Auction Market Preferred Stock ("AMPS") are Preferred Shares of the Fund, with a
par value of $.05 per share and a liquidation preference of $25,000 per share,
that entitle their holders to receive cash dividends at an annual rate that may
vary for the successive dividend periods. The yield in effect at October 31,
1998 was 3.23%.

Shares issued and outstanding during the years ended October 31, 1998 and
October 31, 1997 remained constant.

The Fund pays commissions to certain broker-dealers at the end of each auction
at an annual rate ranging from 0.25% to 0.375%, calculated on the proceeds of
each auction. For the year ended October 31, 1998, Merrill Lynch, Pierce, Fenner
& Smith Inc., an affiliate of FAM, earned $67,303 as commissions.

5. Subsequent Event:

On November 5, 1998, the Fund's Board of Trustees declared an ordinary income
dividend to holders of Common Shares in the amount of $.083059 per share,
payable on November 27, 1998 to shareholders of record as of November 20, 1998.

1. Significant Accounting Policies:

MuniYield Pennsylvania Fund (the "Fund") is registered under the Investment
Company Act of 1940 as a non-diversified, closed-end management investment
company. The Fund's financial statements are prepared in accordance with
generally accepted accounting principles which may require the use of management
accruals and estimates. These unaudited financial statements reflect all
adjustments which are, in the opinion of management, necessary to a fair
statement of the results for the interim period presented. All such adjustments
are of a normal recurring nature. The Fund determines and makes available for
publication the net asset value of its Common Shares on a weekly basis. The
Fund's Common Shares are listed on the New York Stock Exchange under the symbol
MPA. The following is a summary of significant accounting policies followed by
the Fund.

(a) Valuation of investments -- Municipal bonds are traded primarily in the
over-the-counter markets and are valued at the most recent bid price or yield
equivalent as obtained by the Fund's pricing service from dealers that make
markets in such securities. Financial futures contracts and options thereon,
which are traded on exchanges, are valued at their closing prices as of the
close of such exchanges. Options written or purchased are valued at the last
sale price in the case of exchange-traded options. In the case of options traded
in the over-the-counter market, valuation is the last asked price (options
written) or the last bid price (options purchased). Securities with remaining
maturities of sixty days or less are valued at amortized cost, which
approximates market value. Securities and assets for which market quotations are
not readily available are valued at their fair value as determined in good faith
by or under the direction of the Board of Trustees of the Fund, including
valuations furnished by a pricing service retained by the Fund, which may
utilize a matrix system for valuations. The procedures of the pricing service
and its valuations are reviewed by the officers of the Fund under the general
supervision of the Board of Trustees.

(b) Derivative financial instruments -- The Fund may engage in various portfolio
strategies to seek to increase its return by hedging its portfolio against
adverse movements in the debt markets. Losses may arise due to changes in the
value of the contract or if the counterparty does not perform under the
contract.

 . Financial futures contracts -- The Fund may purchase or sell financial futures
contracts and options on such futures contracts for the purpose of hedging the
market risk on existing securities or the intended purchase of securities.
Futures contracts are contracts for delayed delivery of securities at a specific
future date and at a specific price or yield. Upon entering into a contract, the
Fund deposits and maintains as collateral such initial margin as required by the
exchange on which the transaction is effected. Pursuant to the contract, the
Fund agrees to receive from or pay to the broker an amount of cash equal to the
daily fluctuation in value of the contract. Such receipts or payments are known
as variation margin and are recorded by the Fund as unrealized gains or losses.
When the contract is closed, the Fund records a realized gain or loss equal to
the difference between the value of the contract at the time it was opened and
the value at the time it was closed.

 . Options -- The Fund is authorized to write covered call options and purchase
put options. When the Fund writes an option, an amount equal to the premium
received by the Fund is reflected as an asset and an equivalent liability. The
amount of the liability is subsequently marked to market to reflect the current
market value of the option written.

When a security is purchased or sold through an exercise of an option, the
related premium paid (or received) is added to (or deducted from) the basis of
the security acquired or deducted from (or added to) the proceeds of the
security sold. When an option expires (or the Fund enters into a closing
transaction), the Fund realizes a gain or loss on the option to the extent of
the premiums received or paid (or gain or loss to the extent the cost of the
closing transaction exceeds the premium paid or received).

Written and purchased options are non-income producing investments.

(c) Income taxes -- It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no Federal income tax provision is required.

(d) Security transactions and investment income -- Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Interest income is recognized on the accrual basis.

NOTES TO FINANCIAL STATEMENTS (concluded)
- --------------------------------------------------------------------------------

Discounts and market premiums are amortized into interest income. Realized gains
and losses on security transactions are determined on the identified cost basis.

(e) Dividends and distributions -- Dividends from net investment income are
declared and paid monthly. Distributions of capital gains are recorded on the
ex-dividend dates.

2. Investment Advisory Agreement and Transactions with Affiliates:

The Fund has entered into an Investment Advisory Agreement with Fund Asset
Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc.
("PSI"), an indirect wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML &
Co."), which is the limited partner.

FAM is responsible for the management of the Fund's portfolio and provides the
necessary personnel, facilities, equipment and certain other services necessary
to the operations of the Fund. For such services, the Fund pays a monthly fee at
an annual rate of 0.50% of the Fund's average weekly net assets, including
proceeds from the issuance of Preferred Shares.

Accounting services are provided to the Fund by FAM at cost.

Certain officers and/or Trustees of the Fund are officers and/or directors of
FAM, PSI, and/or ML & Co.

4. Beneficial Interest Transactions:

The Fund is authorized to issue an unlimited number of shares of beneficial
interest, including Preferred Shares, par value $.10 per share, all of which
were initially classified as Common Shares. The Board of Trustees is authorized,
however, to reclassify any unissued shares of beneficial interest without
approval of the holders of Common Shares.

Common Shares

Shares issued and outstanding during the six months ended April 30, 1999 and the
year ended October 31, 1998 increased by 91,016 and 49,322, respectively, as a
result of dividend reinvestment.

Preferred Shares

Auction Market Preferred Shares ("AMPS") are Preferred Shares of the Fund, with
a par value of $.05 per share and a liquidation preference of $25,000 per share,
that entitle their holders to receive cash dividends at an annual rate that may
vary for the successive dividend periods. The yield in effect at April 30, 1999
was 3.25%.

Shares issued and outstanding during the six months ended April 30, 1999 and the
year ended October 31, 1998 remained constant.

The Fund pays commissions to certain broker-dealers at the end of each auction
at an annual rate ranging from 0.25% to 0.375%, calculated on the proceeds of
each auction. For the six months ended April 30, 1999, Merrill Lynch, Pierce,
Fenner & Smith Incorporated, an affiliate of FAM, earned $30,216 as commissions.

5. Subsequent Event:

On May 6, 1999, the Fund's Board of Trustees declared an ordinary income
dividend to holders of Common Shares in the amount of $.066757 per share,
payable on May 27, 1999 to shareholders of record as of May 21, 1999.

                            MuniVest Pennsylvania Insured Fund, October 31, 1998
- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

1. Significant Accounting Policies:

MuniVest Pennsylvania Insured Fund (the "Fund") is registered under the
Investment Company Act of 1940 as a non-diversified, closed-end management
investment company. The Fund determines and makes available for publication the
net asset value of its Common Shares on a weekly basis. The Fund's Common Shares
are listed on the New York Stock Exchange under the symbol MVP. The following is
a summary of significant accounting policies followed by the Fund.

(a) Valuation of investments -- Municipal bonds are traded primarily in the
over-the-counter markets and are valued at the most recent bid price or yield
equivalent as obtained by the Fund's pricing service from dealers that make
markets in such securities. Financial futures contracts and options thereon,
which are traded on exchanges, are valued at their closing prices as of the
close of such exchanges. Options written or purchased are valued at the last
sale price in the case of exchange-traded options. In the case of options traded
in the over-the-counter market, valuation is the last asked price (options
written) or the last bid price (options purchased). Securities with remaining
maturities of sixty days or less are valued at amortized cost, which
approximates market value. Securities and assets for which market quotations are
not readily available are valued at fair value as determined in good faith by or
under the direction of the Board of Trustees of the Fund, including valuations
furnished by a pricing service retained by the Fund, which may utilize a matrix
system for valuations. The procedures of the pricing service and its valuations
are reviewed by the officers of the Fund under the general supervision of the
Board of Trustees.

(b) Derivative financial instruments -- The Fund may engage in various portfolio
strategies to seek to increase its return by hedging its portfolio against
adverse movements in the debt markets. Losses may arise due to changes in the
value of the contract or if the counterparty does not perform under the
contract.

o Financial futures contracts -- The Fund may purchase or sell financial futures
contracts and options on such futures contracts for the purpose of hedging the
market risk on existing securities or the intended purchase of securities.
Futures contracts are contracts for delayed delivery of securities at a specific
future date and at a specific price or yield. Upon entering into a contract, the
Fund deposits and maintains as collateral such initial margin as required by the
exchange on which the transaction is effected. Pursuant to the contract, the
Fund agrees to receive from or pay to the broker an amount of cash equal to the
daily fluctuation in value of the contract. Such receipts or payments are known
as variation margin and are recorded by the Fund as unrealized gains or losses.
When the contract is closed, the Fund records a realized gain or loss equal to
the difference between the value of the contract at the time it was opened and
the value at the time it was closed.

o Options -- The Fund is authorized to write covered call options and purchase
put options. When the Fund writes an option, an amount equal to the premium
received by the Fund is reflected as an asset and an equivalent liability. The
amount of the liability is subsequently marked to market to reflect the current
market value of the option written. When a security is purchased or sold through
an exercise of an option, the related premium paid (or received) is added to (or
deducted from) the basis of the security acquired, or deducted from (or added
to) the proceeds of the security sold. When an option expires (or the Fund
enters into a closing transaction), the Fund realizes a gain or loss on the
option to the extent of the premiums received or paid (or gain or loss to the
extent the cost of the closing transaction exceeds the premium paid or
received).

Written and purchased options are non-income producing investments.

(c) Income taxes -- It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute sub stantially all of its taxable income to its shareholders.
Therefore, no Federal income tax provision is required.

(d) Security transactions and investment income -- Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Interest income is recognized on the accrual basis. Discounts and market
premiums are amortized into interest income. Realized gains and losses on
security transactions are determined on the identified cost basis.

(e) Deferred organization expenses -- Deferred organization expenses are
amortized on a straight-line basis over a period not exceeding five years.




                                     F-32


(f) Dividends and distributions -- Dividends from net investment income are
declared and paid monthly. Distributions of capital gains are recorded on the
ex-dividend dates.

2. Investment Advisory Agreement and Transactions with Affiliates:

The Fund has entered into an Investment Advisory Agreement with Fund Asset
Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc.
("PSI"), an indirect wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML &
Co."), which is the limited partner.

FAM is responsible for the management of the Fund's portfolio and provides the
necessary personnel, facilities, equipment and certain other services necessary
to the operations of the Fund. For such services, the Fund pays a monthly fee at
an annual rate of 0.50% of the Fund's average weekly net assets, including
proceeds from the issuance of Preferred Shares.

Accounting services are provided to the Fund by FAM at cost.

Certain officers and/or trustees of the Fund are officers and/or directors of
FAM, PSI, and/or ML & Co.

securities and $106 related to depreciated securities. The aggregate cost of
investments at October 31, 1998 for Federal income tax purposes was $79,051,894.

4. Capital Share Transactions:

The Fund is authorized to issue an unlimited number of shares of beneficial
interest, including Preferred Shares, par value $.10 per share, all of which
were initially classified as Common Shares. The Board of Trustees is authorized,
however, to reclassify any unissued shares of capital without approval of the
holders of Common Shares.

Common Shares

by 4,120 as a result of dividend reinvestment and during the year ended October
31, 1997 remained constant.

Preferred Shares

a par value of $.05 per share and a liquidation preference of $25,000 per share,
that entitle their holders to receive cash dividends at an annual rate that may
vary for the successive dividend periods. The yield in effect at October 31,
1998 was 2.40%.

Shares issued and outstanding during the years ended October 31, 1998 and
October 31, 1997 remained constant.

The Fund pays commissions to certain broker-dealers at the end of each auction
at an annual rate ranging from 0.25% to 0.375%, calculated on the proceeds of
each auction. For the year ended October 31, 1998, Merrill Lynch, Pierce, Fenner
& Smith Inc., an affiliate of FAM, earned $40,877 as commissions.

NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

1. Significant Accounting Policies:

MuniVest Pennsylvania Insured Fund (the "Fund") is registered under the
Investment Company Act of 1940 as a non-diversified, closed-end management
investment company. The Fund's financial statements are prepared in accordance
with generally accepted accounting principles which may require the use of
management accruals and estimates. These unaudited financial statements reflect
all adjustments which are, in the opinion of management, necessary to a fair
statement of the results for the interim period presented. All such adjustments
are of a normal recurring nature. The Fund determines and makes available for
publication the net asset value of its Common Shares on a weekly basis. The
Fund's Common Shares are listed on the New York Stock Exchange under the symbol
MVP. The following is a summary of significant accounting policies followed by
the Fund.

(a) Valuation of investments -- Municipal bonds are traded primarily in the
over-the-counter markets and are valued at the most recent bid price or yield
equivalent as obtained by the Fund's pricing service from dealers that make
markets in such securities. Financial futures contracts and options thereon,
which are traded on exchanges, are valued at their closing prices as of the
close of such exchanges. Options written or purchased are valued at the last
sale price in the case of exchange-traded options. In the case of options traded
in the over-the-counter market, valuation is the last asked price (options
written) or the last bid price (options purchased). Securities with remaining
maturities of sixty days or less are valued at amortized cost, which
approximates market value. Securities and assets for which market quotations are
not readily available are valued at fair value as determined in good faith by or
under the direction of the Board of Trustees of the Fund, including valuations
furnished by a pricing service retained by the Fund, which may utilize a matrix
system for valuations. The procedures of the pricing service and its valuations
are reviewed by the officers of the Fund under the general supervision of the
Board of Trustees.

(b) Derivative financial instruments -- The Fund may engage in various portfolio
strategies to seek to increase its return by hedging its portfolio against
adverse movements in the debt markets. Losses may arise due to changes in the
value of the contract or if the counterparty does not perform under the
contract.

o Financial futures contracts -- The Fund may purchase or sell financial futures
contracts and options on such futures contracts for the purpose of hedging the
market risk on existing securities or the intended purchase of securities.
Futures contracts are contracts for delayed delivery of securities at a specific
future date and at a specific price or yield. Upon entering into a contract, the
Fund deposits and maintains as collateral such initial margin as required by the
exchange on which the transaction is effected. Pursuant to the contract, the
Fund agrees to receive from or pay to the broker an amount of cash equal to the
daily fluctuation in value of the contract. Such receipts or payments are known
as variation margin and are recorded by the Fund as unrealized gains or losses.
When the contract is closed, the Fund records a realized gain or loss equal to
the difference between the value of the contract at the time it was opened and
the value at the time it was closed.

o Options -- The Fund is authorized to write covered call options and purchase
put options. When the Fund writes an option, an amount equal to the premium
received by the Fund is reflected as an asset and an equivalent liability. The
amount of the liability is subsequently marked to market to reflect the current
market value of the option written. When a security is purchased or sold through
an exercise of an option, the related premium paid (or received) is added to (or
deducted from) the basis of the security acquired, or deducted from (or added
to) the proceeds of the security sold. When an option expires (or the Fund
enters into a closing transaction), the Fund realizes a gain or loss on the
option to the extent of the premiums received or paid (or gain or loss to the
extent the cost of the closing transaction exceeds the premium paid or
received).

Written and purchased options are non-income producing investments.

(c) Income taxes -- It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no Federal income tax provision is required.

(d) Security transactions and investment income -- Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Interest income is recognized on the accrual basis. Discounts and market
premiums are amortized into interest income. Realized gains and losses on
security transactions are determined on the identified cost basis.


                                     F-42


(e) Dividends and distributions -- Dividends from net investment income are
declared and paid monthly. Distributions of capital gains are recorded on the
ex-dividend dates.

2. Investment Advisory Agreement and Transactions with Affiliates:

The Fund has entered into an Investment Advisory Agreement with Fund Asset
Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc.
("PSI"), an indirect wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML &
Co."), which is the limited partner.

FAM is responsible for the management of the Fund's portfolio and provides the
necessary personnel, facilities, equipment and certain other services necessary
to the operations of the Fund. For such services, the Fund pays a monthly fee at
an annual rate of 0.50% of the Fund's average weekly net assets, including
proceeds from the issuance of Preferred Shares.

Accounting services are provided to the Fund by FAM at cost.

Certain officers and/or trustees of the Fund are officers and/or directors of
FAM, PSI, and/or ML & Co.

3. Investments:

Purchases and sales of investments, excluding short-term securities, for the six
months ended April 30, 1999 were $15,375,027 and $20,704,109, respectively.

Net realized gains for the six months ended April 30, 1999 and net unrealized
gains as of April 30, 1999 were as follows:

- --------------------------------------------------------------------------------
                                                   Realized           Unrealized
                                                     Gains              Gains

Total ..................................          $  297,931          $3,932,052
                                                  ==========          ==========
- --------------------------------------------------------------------------------

As of April 30, 1999, net unrealized appreciation for Federal income tax
purposes aggregated $3,932,052, of which $4,004,277 related to appreciated
securities and $72,225 related to depreciated securities. The aggregate cost of
investments at April 30, 1999 for Federal income tax purposes was $76,924,058.

4. Capital Shares Transactions:

The Fund is authorized to issue an unlimited number of shares of beneficial
interest, including Preferred Shares, par value $.10 per share, all of which
were initially classified as Common Shares. The Board of Trustees is authorized,
however, to reclassify any unissued shares of capital without approval of the
holders of Common Shares.

Common Shares

Shares issued and outstanding during the six months ended April 30, 1999 and the
year ended October 31, 1998 increased by 8,203 and 4,120, respectively, as a
result of dividend reinvestment.

Preferred Shares

Auction Market Preferred Shares ("AMPS") are Preferred Shares of the Fund, with
a par value of $.05 per share and a liquidation preference of $25,000 per share,
that entitle their holders to receive cash dividends at an annual rate that may
vary for the successive dividend periods. The yield in effect at April 30, 1999
was 3.50%.

Shares issued and outstanding during the six months ended April 30, 1999 and the
year ended October 31, 1998 remained constant.

The Fund pays commissions to certain broker-dealers at the end of each auction
at an annual rate ranging from 0.25% to 0.375%, calculated on the proceeds of
each auction. For the six months ended April 30, 1999, Merrill Lynch, Pierce,
Fenner & Smith Incorporated, an affiliate of FAM, earned $16,699 as commissions.

5. Capital Loss Carryforward:

At October 31, 1998, the Fund had a net capital loss carryforward of
approximately $5,878,000, of which $1,807,000 expires in 2002, $3,117,000
expires in 2003 and $954,000 expires in 2004. This amount will be available to
offset like amounts of any future taxable gains.

6. Subsequent Event:

On May 6, 1999, the Fund's Board of Trustees declared an ordinary income
dividend to Common Shareholders in the amount of $.058103 per share, payable on
May 27, 1999 to shareholders of record as of May 21, 1999.

NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

1. Significant Accounting Policies:

MuniHoldings Pennsylvania Insured Fund (the "Fund") is registered under the
Investment Company Act of 1940 as a non-diversified, closed-end management
investment company. The Fund's financial statements are prepared in accordance
with generally accepted accounting principles which may require the use of
management accruals and estimates. These unaudited financial statements reflect
all adjustments which are, in the opinion of management, necessary to a fair
statement of the results for the interim period presented. All such adjustments
are of a normal recurring nature. Prior to commencement of operations on
February 26, 1999, the Fund had no operations other than those relating to
organizational matters and the sale of 6,667 shares of Common Shares on January
13, 1999 to Fund Asset Management, L.P. ("FAM") for $100,005. The Fund
determines and makes available for publication the net asset value of its Common
Shares on a weekly basis. The Fund's Common Shares are listed on the American
Stock Exchange under the symbol MPI. The following is a summary of significant
accounting policies followed by the Fund.

(a) Valuation of investments -- Municipal bonds are traded primarily in the
over-the-counter markets and are valued at the most recent bid price or yield
equivalent as obtained by the Fund's pricing service from dealers that make
markets in such securities. Financial futures contracts and options thereon,
which are traded on exchanges, are valued at their closing prices as of the
close of such exchanges. Options written or purchased are valued at the last
sale price in the case of exchange-traded options. In the case of options traded
in the over-the-counter market, valuation is the last asked price (options
written) or the last bid price (options purchased). Securities with remaining
maturities of sixty days or less are valued at amortized cost, which
approximates market value. Securities and assets for which market quotations are
not readily available are valued at fair value as determined in good faith by or
under the direction of the Board of Trustees of the Fund, including valuations
furnished by a pricing service retained by the Fund, which may utilize a matrix
system for valuations. The procedures of the pricing service and its valuations
are reviewed by the officers of the Fund under the general supervision of the
Board of Trustees.

(b) Derivative financial instruments -- The Fund may engage in various portfolio
strategies to seek to increase its return by hedging its portfolio against
adverse movements in the debt markets. Losses may arise due to changes in the
value of the contract or if the counterparty does not perform under the
contract.

 . Financial futures contracts -- The Fund may purchase or sell financial futures
contracts and options on such futures contracts for the purpose of hedging the
market risk on existing securities or the intended purchase of securities.
Futures contracts are contracts for delayed delivery of securities at a specific
future date and at a specific price or yield. Upon entering into a contract, the
Fund deposits and maintains as collateral such initial margin as required by the
exchange on which the transaction is effected. Pursuant to the contract, the
Fund agrees to receive from or pay to the broker an amount of cash equal to the
daily fluctuation in value of the contract. Such receipts or payments are known
as variation margin and are recorded by the Fund as unrealized gains or losses.
When the contract is closed, the Fund records a realized gain or loss equal to
the difference between the value of the contract at the time it was opened and
the value at the time it was closed.

 . Options -- The Fund is authorized to write covered call options and purchase
call and put options. When the Fund writes an option, an amount equal to the
premium received by the Fund is reflected as an asset and an equivalent
liability. The amount of the liability is subsequently marked to market to
reflect the current market value of the option written.

When a security is purchased or sold through an exercise of an option, the
related premium paid (or received) is added to (or deducted from) the basis of
the security acquired or deducted from (or added to) the proceeds of the
security sold. When an option expires (or the Fund enters into a closing
transaction), the Fund realizes a gain or loss on the option to the extent of
the premiums received or paid (or gain or loss to the extent the cost of the
closing transaction exceeds the premium paid or received).

Written and purchased options are non-income producing investments.

(c) Income taxes -- It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no Federal income tax provision is required.

(d) Security transactions and investment income -- Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Interest income is recognized on the accrual basis. Discounts and market
premiums are amortized into interest income. Realized gains and losses on
security transactions are determined on the identified cost basis.

4. Beneficial Interest Transactions:

The Fund is authorized to issue an unlimited number of shares of beneficial
interest, including Preferred Shares, par value $.10 per share, all of which
were initially classified as Common Shares. The Board of Trustees is authorized,
however, to reclassify any unissued shares of capital without approval of the
holders of Common Shares.

Common Shares

Shares issued and outstanding during the period February 26, 1999 to March 31,
1999 increased by 2,075,000 as a result of the initial offering.

Preferred Shares

Auction Market Preferred Shares ("AMPS") are Preferred Shares of the Fund, with
a par value of $.10 per share and a liquidation preference of $25,000 per share,
that entitle their holders to receive cash dividends at an annual rate that may
vary for the successive dividend periods. The yield in effect at March 31, 1999
was 3.30%.

In connection with the offering of AMPS, the Board of Trustees reclassified 820
shares of unissued beneficial interest as AMPS. Shares issued and outstanding
during the period February 26, 1999 to March 31, 1999 increased by 820 as a
result of the AMPS offering.

The Fund pays commissions to certain broker-dealers at the end of each auction
at an annual rate ranging from 0.25% to 0.375%, calculated on the proceeds of
each auction. For the period February 26, 1999 to March 31, 1999, MLPF&S, an
affiliate of FAM, earned $1,000 as commissions.

                      MUNIVEST PENNSYLVANIA INSURED FUND
                  AND MUNIHOLDINGS PENNSYLVANIA  INSURED FUND

                    COMBINED NOTES TO FINANCIAL STATEMENTS

1.  Significant Accounting Policies:

  MuniYield Pennsylvania Fund (the "Fund," which term as used herein shall
refer to MuniYield Pennsylvania Fund, after giving effect to the
Reorganization) is registered under the Investment Company Act of 1940 as a
non-diversified, closed-end management investment company. The Fund's
financial statements are prepared in accordance with generally accepted
accounting principles which may require the use of management accruals and
estimates. These unaudited financial statements reflect all adjustments which
are, in the opinion of management, necessary to a fair statement of the
results for the interim period presented. The Fund determines and makes
available for publication the net asset value of its Common Shares on a weekly
basis. The Fund's Common Shares are listed on the New York Stock Exchange
under the symbol MPA. The following is a summary of significant accounting
policies followed by the Fund.

  (a) Valuation of investments -- Municipal bonds are traded primarily in the
over-the-counter markets and are valued at the most recent bid price or yield
equivalent as obtained by the Fund's pricing service from dealers that make
markets in such securities. Financial futures contracts and options thereon,
which are traded on exchanges, are valued at their closing prices as of the
close of such exchanges. Options written or purchased are valued at the last
sale price in the case of exchange-traded options. In the case of options
traded in the over-the-counter market, valuation is the last asked price
(options written) or the last bid price (options purchased). Securities with
remaining maturities of sixty days or less are valued at amortized cost, which
approximates market value. Securities and assets for which market quotations
are not readily available are valued at their fair value as determined in good
faith by or under the direction of the Board of Trustees of the Fund,
including valuations furnished by a pricing service retained by the Fund,
which may utilize a matrix system for valuations. The procedures of the
pricing service and its valuations are reviewed by the officers of the Fund
under the general supervision of the Board of Trustees.

  (b) Derivative financial instruments -- The Fund may engage in various
portfolio strategies to seek to increase its return by hedging its portfolio
against adverse movements in the debt markets. Losses may arise due to changes
in the value of the contract or if the counterparty does not perform under the
contract.

  .  Financial futures contracts -- The Fund may purchase or sell financial
     futures contracts and options on such futures contracts for the purpose
     of hedging the market risk on existing securities or the intended
     purchase of securities. Futures contracts are contracts for delayed
     delivery of securities at a specific future date and at a specific price
     or yield. Upon entering into a contract, the Fund deposits and maintains
     as collateral such initial margin as required by the exchange on which
     the transaction is effected. Pursuant to the contract, the Fund agrees
     to receive from or pay to the broker an amount of cash equal to the
     daily fluctuation in value of the contract. Such receipts or payments
     are known as variation margin and are recorded by the Fund as unrealized
     gains or losses. When the contract is closed, the Fund records a
     realized gain or loss equal to the difference between the value of the
     contract at the time it was opened and the value at the time it was
     closed.

  .  Options -- The Fund is authorized to write covered call options and
     purchase put options. When the Fund writes an option, an amount equal to
     the premium received by the Fund is reflected as an asset and an
     equivalent liability. The amount of the liability is subsequently marked
     to market to reflect the current market value of the option written.

     When a security is purchased or sold through an exercise of an option,
     the related premium paid (or received) is added to (or deducted from)
     the basis of the security acquired or deducted from (or added to) the
     proceeds of the security sold. When an option expires (or the Fund
     enters into a closing transaction), the Fund realizes a gain or loss on
     the option to the extent of the premiums received or paid (or gain or
     loss to the extent the cost of the closing transaction exceeds the
     premium paid or received).

                                     F-61


                         MUNIYIELD PENNSYLVANIA FUND,
                      MUNIVEST PENNSYLVANIA INSURED FUND
                  AND MUNIHOLDINGS PENNSYLVANIA  INSURED FUND

            COMBINED NOTES TO FINANCIAL STATEMENTS (Concluded)

     Written and purchased options are non-income producing investments.

  (c) Income taxes -- It is the Fund's policy to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and
to distribute substantially all of its taxable income to its shareholders.
Therefore, no Federal income tax provision is required.

  (d) Security transactions and investment income -- Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Interest income is recognized on the accrual basis. Discounts and market
premiums are amortized into interest income. Realized gains and losses on
security transactions are determined on the identified cost basis.

  (e) Offering expenses -- Direct expenses relating to the public offering of
the Fund's Common and Preferred shares were charged to capital at the time of
issuance of the shares.

  (f) Dividends and distributions -- Dividends from net investment income are
declared and paid monthly. Distributions of capital gains are recorded on the
ex-dividend dates.

  (g) Custodian bank -- The MuniHoldings Pennsylvania Insured Fund recorded an
amount payable to the Custodian bank reflecting an overnight overdraft, which
resulted from timing differences of security transaction settlements.

2. Investment Advisory Agreement and Transactions with Affiliates:

  The Fund has entered into an Investment Advisory Agreement with Fund Asset
Management, L.P. ("FAM"). The general partner of FAM is Princeton Services,
Inc. ("PSI"), an indirect wholly-owned subsidiary of Merrill Lynch & Co., Inc.
("ML & Co."), which is the limited partner.

  FAM is responsible for the management of the Fund's portfolio and provides
the necessary personnel, facilities, equipment and certain other services
necessary to the operations of the Fund. For such services, the Fund pays a
monthly fee at an annual rate of 0.50% of the Fund's average weekly net
assets, including proceeds from the issuance of Preferred Shares.

  For MuniHoldings Pennsylvania Insured Fund, FAM earned fees of $39,499 for

                     AGREEMENT AND PLAN OF REORGANIZATION

  THIS AGREEMENT AND PLAN OF REORGANIZATION (this "Agreement") is made as of
the 9th day of November, 1999, by and between MuniYield Pennsylvania Fund, a
Massachusetts business trust ("MuniYield Pennsylvania"), MuniVest Pennsylvania
Insured Fund, a Massachusetts business trust ("MuniVest Pennsylvania") and
MuniHoldings Pennsylvania Insured Fund, a Massachusetts business trust
("MuniHoldings Pennsylvania") (MuniYield Pennsylvania, MuniVest Pennsylvania
and MuniHoldings Pennsylvania are sometimes referred to herein collectively as
the "Funds"; MuniVest Pennsylvania and MuniHoldings Pennsylvania are sometimes
referred to herein collectively as the "Acquired Funds").

                            PLAN OF REORGANIZATION

  The reorganization will comprise the following:

    (a) (1) the acquisition by MuniYield Pennsylvania of substantially all of
  the assets, and the assumption by MuniYield Pennsylvania of substantially
  all of the liabilities of MuniVest Pennsylvania in exchange solely for an
  equal aggregate value of newly issued (A) common shares, with a par value
  of $0.10 per share ("Common Shares"), of MuniYield Pennsylvania ("MuniYield
  Pennsylvania Common Shares") and (B) auction market preferred shares
  ("AMPS") of MuniYield Pennsylvania, with a liquidation preference of
  $25,000 per share plus an amount equal to accumulated but unpaid dividends
  thereon (whether or not earned or declared) to be designated Series B
  ("MuniYield Pennsylvania Series B AMPS"), and (2) the subsequent
  distribution by MuniVest Pennsylvania to MuniVest Pennsylvania shareholders
  of (x) all of the MuniYield Pennsylvania Common Shares received by MuniVest
  Pennsylvania in exchange for such shareholders' Common Shares, with a par
  value of $0.10 per share, of MuniVest Pennsylvania ("MuniVest Pennsylvania
  Common Shares") and (y) all of the MuniYield Pennsylvania Series B AMPS
  received by MuniVest Pennsylvania in exchange for such shareholders'
  outstanding shares of AMPS shares of MuniVest Pennsylvania, with a
  liquidation preference of $25,000 per share plus an amount equal to
  accumulated but unpaid dividends thereon (whether or not earned or
  declared) ("MuniVest Pennsylvania AMPS");

    (b) (1) the acquisition by MuniYield Pennsylvania of substantially all of
  the assets, and the assumption by MuniYield Pennsylvania of substantially
  all of the liabilities of MuniHoldings Pennsylvania in exchange solely for
  an equal aggregate value of newly issued shares of (A) MuniYield
  Pennsylvania Common Shares and (B) MuniYield Pennsylvania Series B AMPS and
  (2) the subsequent distribution by MuniHoldings Pennsylvania to
  MuniHoldings Pennsylvania shareholders of (x) all of the MuniYield
  Pennsylvania Common Shares received by MuniHoldings Pennsylvania in
  exchange for such shareholders' Common Shares, with a par value of $0.10
  per share, of MuniHoldings Pennsylvania ("MuniHoldings Pennsylvania Common
  Shares") and (y) all of the MuniYield Pennsylvania Series B AMPS received
  by MuniHoldings Pennsylvania in exchange for such shareholders' shares of
  AMPS, of MuniHoldings Pennsylvania, with a liquidation preference of
  $25,000 per share plus an amount equal to accumulated but unpaid dividends
  thereon (whether or not earned or declared) designated Series A
  ("MuniHoldings Pennsylvania AMPS");

  all upon and subject to the terms hereinafter set forth (collectively, the
  "Reorganization").

  In the course of the Reorganization, MuniYield Pennsylvania Common Shares,
and MuniYield Pennsylvania Series B AMPS will be distributed to the
shareholders of the Acquired Funds as follows:

    (a) (1) each holder of MuniVest Pennsylvania Common Shares will be
  entitled to receive a number of MuniYield Pennsylvania Common Shares equal
  to the aggregate net asset value of the MuniVest Pennsylvania Common Shares
  owned by such shareholder on the Exchange Date; and (2) each holder of
  MuniVest Pennsylvania AMPS will be entitled to receive a number of shares
  of MuniYield Pennsylvania

                                     II-1


  Series B AMPS equal to the aggregate liquidation preference (and aggregate
  value) of the MuniVest Pennsylvania AMPS owned by such shareholder on the
  Exchange Date; and

    (b) (1)  each holder of MuniHoldings Pennsylvania Common Shares will be
  entitled to receive a number of shares of MuniYield Pennsylvania Common
  Shares equal to the aggregate net asset value of the MuniHoldings
  Pennsylvania Common Shares owned by such shareholder on the Exchange Date;
  and (2) each holder of MuniHoldings Pennsylvania AMPS will be entitled to
  receive a number of shares of MuniYield Pennsylvania Series B AMPS equal to
  the aggregate liquidation preference (and aggregate value) of the
  MuniHoldings Pennsylvania AMPS owned by such shareholder on the Exchange
  Date.

  It is intended that the Reorganization described in this Plan shall be a
reorganization within the meaning of Section 368(a)(1)(C) of the Internal
Revenue Code of 1986, as amended (the "Code"), and any successor provision.

  Prior to the Exchange Date, each Acquired Fund shall declare a dividend or
dividends which, together with all such previous dividends, shall have the
effect of distributing to their respective shareholders all of their
respective net investment company taxable income to and including the Exchange
Date, if any (computed without regard to any deduction for dividends paid),
and all of its net capital gain, if any, realized to and including the
Exchange Date. In this regard and in connection with the Reorganization, the
last dividend period for the MuniVest Pennsylvania AMPS and MuniHoldings
Pennsylvania AMPS prior to the Exchange Date may be shorter than the dividend
period for such AMPS determined as set forth in the applicable Certificate of
Designation.

  A Certificate of Designation of MuniYield Pennsylvania, designating the
currently outstanding series of AMPS of MuniYield Pennsylvania as Series A and
establishing the powers, rights and preferences of the MuniYield Pennsylvania
Series B AMPS will have been filed with the Office of the Secretary of State
of the Commonwealth of Massachusetts prior to the Exchange Date.

  As promptly as practicable after the consummation of the Reorganization,
each Acquired Fund shall be dissolved in accordance with the laws of the
Commonwealth of Massachusetts and will terminate its registration under the
Investment Company Act of 1940, as amended (the "1940 Act").

                                   AGREEMENT

  In order to consummate the Reorganization and in consideration of the
promises and the covenants and agreements hereinafter set forth, and intending

  in conformity with generally accepted accounting principles applied on a
  consistent basis.

    (f) An unaudited statement of assets, liabilities and capital of
  MuniHoldings Pennsylvania and an unaudited schedule of investments of

    (g) There are no material legal, administrative or other proceedings

  commitment or obligation, and is not subject to any order or

                                     II-7


  decree which would be violated by its execution of or performance under
  this Agreement, except insofar as the Funds have mutually agreed to amend
  such contract or other commitment or obligation to cure any potential
  violation as a condition precedent to the Reorganization.

    (j) MuniHoldings Pennsylvania has no known liabilities of a material
  amount, contingent or otherwise, other than those shown on its statements
  of assets, liabilities and capital referred to above, those incurred in the
  ordinary course of its business as an investment company since September

  the Valuation Time, MuniHoldings Pennsylvania will advise MuniYield
  Pennsylvania and MuniVest Pennsylvania in writing of all known liabilities,
  contingent or otherwise, whether or not incurred in the ordinary course of
  business, existing or accrued as of such time.

    (k) MuniHoldings Pennsylvania has filed, or has obtained extensions to

  Pennsylvania Investments, and MuniYield Pennsylvania will acquire all of
  the MuniHoldings Pennsylvania Investments free and clear of any
  encumbrances, liens or security interests and without any restrictions upon
  the transfer thereof (except those imposed by the Federal or state
  securities laws and those imperfections of title or encumbrances as do not
  materially detract from the value or use of the MuniHoldings Pennsylvania
  Investments or materially affect title thereto).

    (m) No consent, approval, authorization or order of any court or
  governmental authority is required for the consummation by MuniHoldings
  Pennsylvania of the Reorganization, except such as may be required under
  the 1933 Act, the 1934 Act, the 1940 Act or state securities laws.

    (n) The N-14 Registration Statement, on its effective date, at the time

  and nonassessable and has full voting rights.

4.The Reorganization.

  (a) Subject to receiving the requisite approvals of the shareholders of each
of the Funds, and to the other terms and conditions contained herein, (i)
MuniVest Pennsylvania agrees to convey, transfer and deliver to MuniYield
Pennsylvania and MuniYield Pennsylvania agrees to acquire from MuniVest
Pennsylvania on the Exchange Date, all of the MuniVest Pennsylvania
Investments (including interest accrued as of the Valuation Time on debt
instruments) and assume substantially all of the liabilities of MuniVest
Pennsylvania in exchange solely for that number of shares of MuniYield
Pennsylvania Common Shares and MuniYield Pennsylvania Series B AMPS provided
in Section 5 of this Agreement; (ii) MuniHoldings Pennsylvania agrees to
convey, transfer and deliver to MuniYield Pennsylvania and MuniYield
Pennsylvania agrees to acquire from MuniHoldings Pennsylvania on the Exchange

all of the liabilities of MuniHoldings Pennsylvania in exchange solely for
that number of shares of MuniYield Pennsylvania Common Shares and MuniYield
Pennsylvania Series B AMPS provided in Section 5 of this Agreement and (iii)
MuniYield Pennsylvania agrees to change its investment policies to provide
that the Fund, under normal circumstances, will invest at least 80% of its
assets in municipal obligations with remaining maturities of one year or more

Pennsylvania Insured Fund."

  Pursuant to this Agreement, as soon as practicable after the Exchange Date
(i) MuniVest Pennsylvania will distribute all shares of MuniYield Pennsylvania
Common Shares and MuniYield Pennsylvania Series B AMPS received by it to its
shareholders in exchange for their shares of MuniVest Pennsylvania Common
Shares and MuniVest Pennsylvania AMPS and (ii) MuniHoldings Pennsylvania will
distribute all shares of MuniYield Pennsylvania Common Shares and MuniYield
Pennsylvania Series B AMPS received by it to its shareholders in exchange for
their shares of MuniHoldings Pennsylvania Common Shares and MuniHoldings
Pennsylvania AMPS. Such distributions shall be accomplished by the opening of
shareholder accounts on the shares ledger records of MuniYield Pennsylvania in
the amounts due the shareholders of each Acquired Fund based on their
respective holdings in such Acquired Fund as of the Valuation Time.

  (b) Prior to the Exchange Date, each Acquired Fund shall declare a dividend

effect of distributing to their respective shareholders all of their
respective net investment company taxable income to and including the Exchange
Date, if any (computed without regard to any deduction for dividends paid),
and all of its net capital gain, if any, realized to and including the
Exchange Date. In this regard and in connection with the Reorganization, the

period for such AMPS determined as set forth in the applicable Certificate of
Designation.

  (e) Recourse for liabilities assumed from each Acquired Fund by MuniYield
Pennsylvania in the Reorganization will be limited to the net assets of each
such fund acquired by MuniYield Pennsylvania. The known liabilities of the
Acquired Funds, as of the Valuation Time, shall be confirmed in writing to

  (f) The Acquired Funds will each be dissolved following the Exchange Date by
filing separate Certificate of Termination with the Commonwealth of
Massachusetts.

  (g) MuniYield Pennsylvania will file with the Commonwealth of Massachusetts
a Certificate of Designation designating the currently outstanding series of
AMPS of MuniYield Pennsylvania as Series A and establishing the powers, rights
and preferences of the MuniYield Pennsylvania Series B AMPS prior to the
closing of the Reorganization.

  (h) As promptly as practicable after the liquidation of each of the Acquired
Funds pursuant to the Reorganization, each Acquired Fund shall terminate its
respective registration under the 1940 Act.

5. Issuance and Valuation of MuniYield Pennsylvania Common Shares and
   MuniYield Pennsylvania Series B AMPS in the Reorganization.

  Full shares of MuniYield Pennsylvania Common Shares and MuniYield
Pennsylvania Series B AMPS of an aggregate net asset value or liquidation
preference, as the case may be, equal (to the nearest one then thousandth of
one cent) to the value of the assets of MuniVest Pennsylvania acquired in the
Reorganization determined as hereinafter provided, reduced by the amount of
liabilities of MuniVest Pennsylvania assumed by MuniYield Pennsylvania in the
Reorganization, shall be issued by MuniYield Pennsylvania to MuniVest
Pennsylvania in exchange for such assets of MuniVest Pennsylvania, plus cash
in lieu of fractional shares. MuniYield Pennsylvania will issue to MuniVest
Pennsylvania (a) a number of MuniYield Pennsylvania Common Shares, the
aggregate net asset value of which will equal the aggregate net asset value of
the shares of MuniVest Pennsylvania Common Shares, determined as set forth
below, and (b) a number of shares of MuniYield Pennsylvania Series B AMPS, the
aggregate liquidation preference and value of which will equal the aggregate
liquidation preference and value of the MuniVest Pennsylvania AMPS, determined
as set forth below.

  Full shares of MuniYield Pennsylvania Common Shares and MuniYield
Pennsylvania Series B AMPS of an aggregate net asset value or liquidation
preference, as the case may be, equal (to the nearest one ten thousandth of
one cent) to the value of the assets of MuniHoldings Pennsylvania acquired in
the Reorganization determined as hereinafter provided, reduced by the amount
of liabilities of MuniHoldings Pennsylvania assumed by MuniYield Pennsylvania
to MuniHoldings Pennsylvania in the Reorganization, shall be issued by
MuniYield Pennsylvania in exchange for such assets of MuniHoldings
Pennsylvania, plus cash in lieu of fractional shares. MuniYield Pennsylvania
will issue to MuniHoldings Pennsylvania (a) a number of MuniYield Pennsylvania
Common Shares, the aggregate net asset value of which will equal the aggregate
net asset value of the shares of MuniHoldings Pennsylvania Common Shares,
determined as set forth below, and (b) a number of shares of MuniYield
Pennsylvania Series B AMPS, the aggregate liquidation preference and value of
which will equal the aggregate liquidation preference and value of the
MuniHoldings Pennsylvania AMPS, determined as set forth below.

  The net asset value of each of the Funds and the liquidation preference and
value of the AMPS of each of the Funds shall be determined as of the Valuation
Time in accordance with the procedures described in (i) the final prospectus
of MuniYield Pennsylvania, dated September 11, 1992, relating to the MuniYield
Pennsylvania Common Shares and (ii) the prospectus of MuniYield Pennsylvania,
dated November 23, 1992, relating to the MuniYield Pennsylvania AMPS, and no
formula will be used to adjust the net asset value so determined of any Fund
to take into account differences in realized and unrealized gains and losses.
Values in all cases shall be determined as of the Valuation Time. The value of
the Acquired Fund Investments to be transferred to MuniYield Pennsylvania
shall be determined by MuniYield Pennsylvania pursuant to the procedures
utilized by MuniYield Pennsylvania in valuing its own assets and determining
its own liabilities for purposes of the Reorganization.

                                     II-10


Such valuation and determination shall be made by MuniYield Pennsylvania in
cooperation with the Acquired Funds and shall be confirmed in writing by
MuniYield Pennsylvania to the Acquired Funds. The net asset value per share of
the MuniYield Pennsylvania Common Shares and the liquidation preference and
value per share of the MuniYield Pennsylvania Series B AMPS shall be
determined in accordance with such procedures and MuniYield Pennsylvania shall
certify the computations involved. For purposes of determining the net asset
value of Common Shares of each Fund, the value of the securities held by the
Fund plus any cash or other assets (including interest accrued but not yet
received) minus all liabilities (including accrued expenses) and the aggregate
liquidation value of the outstanding shares of AMPS of that Fund is divided by
the total number of shares of Common Shares of that Fund outstanding at such
time.

  MuniYield Pennsylvania shall issue to MuniVest Pennsylvania separate
certificates or share deposit receipts for the MuniYield Pennsylvania Common
Shares and the MuniYield Pennsylvania Series B AMPS, each registered in the
name of MuniVest Pennsylvania. MuniVest Pennsylvania then shall distribute the
MuniYield Pennsylvania Common Shares and the MuniYield Pennsylvania Series B
AMPS to the holders of MuniVest Pennsylvania Common Shares and MuniVest
Pennsylvania AMPS by redelivering the certificates or share deposit receipts
evidencing ownership of (i) the MuniYield Pennsylvania Common Shares to The
Bank of New York as the transfer agent and registrar for the MuniYield
Pennsylvania Common Shares for distribution to the holders of MuniVest
Pennsylvania Common Shares on the basis of such holder's proportionate
interest in the aggregate net asset value of the Common Shares of MuniVest
Pennsylvania and (ii) the MuniYield Pennsylvania Series B AMPS to The Bank of
New York, as the transfer agent and registrar for the MuniYield Pennsylvania
Series B AMPS for distribution to the holders of MuniVest Pennsylvania AMPS on
the basis of such holder's proportionate interest in the aggregate liquidation
preference and value of the AMPS of MuniVest Pennsylvania. With respect to any
MuniVest Pennsylvania shareholder holding certificates evidencing ownership of
either MuniVest Pennsylvania Common Shares or MuniVest Pennsylvania AMPS as of
the Exchange Date, and subject to MuniYield Pennsylvania being informed
thereof in writing by MuniVest Pennsylvania, MuniYield Pennsylvania will not
permit such shareholder to receive new certificates evidencing ownership of
the MuniYield Pennsylvania Common Shares or MuniYield Pennsylvania Series B
AMPS, exchange MuniYield Pennsylvania Common Shares or MuniYield Pennsylvania
Series B AMPS credited to such shareholder's account for shares of other
investment companies managed by Merrill Lynch Asset Management, L.P. ("MLAM")
or any of its affiliates, or pledge or redeem such MuniYield Pennsylvania
Common Shares or MuniYield Pennsylvania Series B AMPS, in any case, until
notified by MuniVest Pennsylvania or its agent that such shareholder has
surrendered his or her outstanding certificates evidencing ownership of
MuniVest Pennsylvania Common Shares or MuniVest Pennsylvania AMPS or, in the
event of lost certificates, posted adequate bond. MuniVest Pennsylvania, at
its own expense, will request its shareholders to surrender their outstanding
certificates evidencing ownership of MuniVest Pennsylvania Common Shares or
MuniVest Pennsylvania AMPS, as the case may be, or post adequate bond
therefor.

  MuniYield Pennsylvania shall issue to MuniHoldings Pennsylvania separate
certificates or share deposit receipts for the MuniYield Pennsylvania Common
Shares and the MuniYield Pennsylvania Series B AMPS, each registered in the
name of MuniHoldings Pennsylvania. MuniHoldings Pennsylvania then shall
distribute the MuniYield Pennsylvania Common Shares and the MuniYield
Pennsylvania Series B AMPS to the holders of MuniHoldings Pennsylvania Common
Shares and MuniHoldings Pennsylvania AMPS by redelivering the certificates or
share deposit receipts evidencing ownership of (i) the MuniYield Pennsylvania
Common Shares to The Bank of New York as the transfer agent and registrar for
the MuniYield Pennsylvania Common Shares for distribution to the holders of
MuniHoldings Pennsylvania Common Shares on the basis of such holder's
proportionate interest in the aggregate net asset value of the Common Shares
of MuniHoldings Pennsylvania and (ii) the MuniYield Pennsylvania Series B AMPS
to The Bank of New York, as the transfer agent and registrar for the MuniYield
Pennsylvania Series B AMPS for distribution to the holders of MuniHoldings
Pennsylvania AMPS on the basis of such holder's proportionate interest in the
aggregate liquidation preference and value of the AMPS of MuniHoldings
Pennsylvania. With respect to any MuniHoldings Pennsylvania shareholder
holding certificates evidencing ownership of either MuniHoldings Pennsylvania
Common Shares or MuniHoldings Pennsylvania AMPS as of the Exchange Date, and
subject to MuniYield Pennsylvania being informed thereof in

                                     II-11


writing by MuniHoldings Pennsylvania, MuniYield Pennsylvania will not permit
such shareholder to receive new certificates evidencing ownership of MuniYield
Pennsylvania Common Shares or MuniYield Pennsylvania Series B AMPS, exchange
MuniYield Pennsylvania Common Shares or MuniYield Pennsylvania Series B AMPS
credited to such shareholder's account for shares of other investment
companies managed by MLAM or any of its affiliates, or pledge or redeem such
MuniYield Pennsylvania Common Shares or MuniYield Pennsylvania Series B AMPS,
in any case, until notified by MuniHoldings Pennsylvania or its agent that
such shareholder has surrendered his or her outstanding certificates
evidencing ownership of MuniHoldings Pennsylvania Common Shares or
MuniHoldings Pennsylvania AMPS or, in the event of lost certificates, posted
adequate bond. MuniHoldings Pennsylvania, at its own expense, will request its
shareholders to surrender their outstanding certificates evidencing ownership
of MuniHoldings Pennsylvania Common Shares or MuniHoldings Pennsylvania AMPS,
as the case may be, or post adequate bond therefor.

  Dividends payable to holders of record of shares of MuniYield Pennsylvania
Common Shares or MuniYield Pennsylvania Series B AMPS, as the case may be, as
of any date after the Exchange Date and prior to the exchange of certificates
by any shareholder of an Acquired Fund shall be payable to such shareholder
without interest; however, such dividends shall not be paid unless and until
such shareholder surrenders the certificates representing Common Shares or
AMPS of the Acquired Funds, as the case may be, for exchange.

  No fractional shares of MuniYield Pennsylvania Common Shares will be issued
to holders of MuniVest Pennsylvania Common Shares or MuniHoldings Pennsylvania
Common Shares. In lieu thereof, MuniYield Pennsylvania's transfer agent, The
Bank of New York, will aggregate all fractional shares of MuniYield
Pennsylvania Common Shares and sell the resulting full shares on the New York
Shares Exchange at the current market price for shares of MuniYield
Pennsylvania Common Shares for the account of all holders of fractional
interests, and each such holder will receive such holder's pro rata share of
the proceeds of such sale upon surrender of such holder's certificates
representing MuniVest Pennsylvania Common Shares or MuniHoldings Pennsylvania
Common Shares.

6.Payment of Expenses.

  (a) With respect to expenses incurred in connection with the Reorganization,
(i) each Fund shall pay all expenses incurred that are attributable solely to
such Fund and the conduct of its business, and (ii) MuniYield Pennsylvania

Fund's net assets at the Valuation Time, all expenses incurred in connection
with the Reorganization, including, but not limited to, all costs related to

be liable to any other party for any damages resulting therefrom, including,
without limitation, consequential damages.

7. Covenants of the Funds.

  (a) MuniYield Pennsylvania and MuniVest Pennsylvania agree to call a special

to call an annual meeting of its shareholders as soon as is practicable after

Reorganization, it will terminate in accordance with the laws of the
Commonwealth of Massachusetts and any other applicable law, it will not make
any distributions of MuniYield Pennsylvania Common Shares or MuniYield
Pennsylvania Series B AMPS, as applicable other than to its respective
shareholders and without first paying or adequately providing for the payment
of all of its respective liabilities not assumed by MuniYield Pennsylvania, if
any, and on and after the Exchange Date it shall not conduct any business
except in connection with its termination.

  (d) Each Acquired Fund undertakes that if the Reorganization is consummated,
it will file an application pursuant to Section 8(f) of the 1940 Act for an
order declaring that such Acquired Fund has ceased to be a registered
investment company.

  (e) MuniYield Pennsylvania will file the N-14 Registration Statement with
the Securities and Exchange Commission (the "Commission") and will use its
best efforts to provide that the N-14 Registration Statement becomes effective
as promptly as practicable. Each Fund agrees to cooperate fully with the
others, and each will furnish to the others the information relating to itself
to be set forth in the N-14 Registration Statement as required by the 1933

the state securities laws.

  (f) MuniYield Pennsylvania has no plan or intention to sell or otherwise
dispose of the Acquired Fund Investments, except for dispositions made in the
ordinary course of business.

  (g) Each of the Funds agrees that by the Exchange Date all of its Federal
and other tax returns and reports required to be filed on or before such date
shall have been filed and all taxes shown as due on said returns either have
been paid or adequate liability reserves have been provided for the payment of
such taxes. In connection with this covenant, the Funds agree to cooperate
with each other in filing any tax return, amended return or claim for refund,
determining a liability for taxes or a right to a refund of taxes or
participating in or conducting any audit or other proceeding in respect of
taxes. MuniYield Pennsylvania agrees to retain for a period of ten (10) years
following the Exchange Date all returns, schedules and work papers and all
material records or other documents relating to tax matters of the Acquired
Funds for each of such Fund's taxable period first ending after the Exchange
Date and for all prior taxable periods. Any information obtained under this
subsection shall be kept confidential except as otherwise may be necessary in
connection with the filing of returns or claims for refund or in conducting an
audit or other proceeding. After the Exchange Date, each of the Acquired Funds
shall prepare, or cause its agents to prepare, any Federal, state or local tax

and Forms 1099 to be duly filed with the appropriate taxing authorities.
Notwithstanding the aforementioned provisions of this subsection, any expenses
incurred by the Acquired Funds (other than for payment of taxes) in connection
with the preparation and filing of said tax returns and Forms 1099 after the
Exchange Date shall be borne by each such Fund to the extent such expenses
have been accrued by such Fund in the ordinary course without regard to the
Reorganization; any excess expenses shall be borne by Fund Asset Management,
L.P. ("FAM") at the time such tax returns and Forms 1099 are prepared.

  (h) The Funds each agree to mail to its respective shareholders of record

  any Vice President) and its Treasurer, and a certificate signed by the
  Fund's President (or any Vice President) and its Treasurer, dated as of the

  Semi-Annual Report as applicable, other than changes in its portfolio
  securities since that date or changes in the market value of its portfolio

  Date, certifying that, as of the Valuation Time and as of the Exchange Date
  all representations and warranties of MuniYield Pennsylvania made in this
  Agreement are true and correct in all material respects with the same

  Brown & Wood LLP, as counsel to the Funds, in form and substance
  satisfactory to the Acquired Funds and dated the Exchange Date, to the
  effect that (i) to the best of such counsel's knowledge, no consent,
  approval, authorization or order of any United States federal court, or
  governmental authority is required for the consummation by the Funds of the
  Reorganization, except such as have been obtained under the 1933 Act, the
  1934 Act and the 1940 Act and the published rules and regulations of the
  Commission thereunder and such as may be required under state securities
  laws; (ii) the N-14 Registration Statement has become effective under the
  1933 Act, no stop order suspending the effectiveness of the N-14
  Registration Statement has been issued and no proceedings for that purpose
  have been instituted or are pending or contemplated under the 1933 Act, and
  the N-14 Registration Statement, and each amendment or supplement thereto,
  as of their respective effective dates, appear on their face to be
  appropriately responsive in all material respects to the requirements of
  the 1933 Act, the 1934 Act and the 1940 Act and the published rules and
  regulations of the Commission thereunder; (iii) the descriptions in the N-
  14 Registration Statement of statutes, legal and governmental proceedings
  and contracts and other documents are accurate and fairly present the
  information required to be shown; (iv) the information in the Joint Proxy

  Applicable to the Funds and their Shareholders" and "Agreement and Plan of
  Reorganization--Tax Consequences of the Reorganization," (other than
  information related to Massachusetts law or legal conclusions involving
  matters of Massachusetts law as to which we express no opinion) to the
  extent that it constitutes matters of law, summaries of legal matters or
  legal conclusions, has been reviewed by such counsel and is correct in all
  material respects as of the date of the Joint Proxy Statement and
  Prospectus; (v) the execution and delivery of the Agreement by the Funds

  parties have agreed to amend such provision as a condition precedent to the
  Reorganization; (vi) such counsel does not know of any statutes, legal or
  governmental proceedings or contracts or other documents related to the
  Reorganization of a character required to be described in the N-14
  Registration Statement which are not described therein or, if required to

  cannot make any representation as to the accuracy or completeness of
  statements of fact in the N-14 Registration Statement or any amendment or
  supplement thereto, nothing has come to their attention that would lead
  them to believe that, on the respective effective dates of the N-14
  Registration Statement and any amendment or supplement thereto, (1) the N-
  14 Registration Statement or any amendment or supplement thereto contained
  any untrue statement of a material fact or omitted to state any material
  fact required to be stated therein or necessary to make the statements
  therein not misleading; and (2) the prospectus included in the N-14

                                     II-15



  opinion or belief as to the financial statements or other financial or
  statistical data relating to any Fund contained or incorporated by
  reference in the N-14 Registration Statement. In giving the opinion set
  forth above, Brown & Wood LLP may state that it is relying on certificates
  of officers of a Fund with regard to matters of fact and certain
  certificates and written statements of governmental officials with respect
  to the good standing of a Fund and the opinion of Bingham Dana LLP as to
  matters of Massachusetts law.

    (f) That the Acquired Funds shall have received an opinion or opinions of
  Bingham Dana LLP, as Massachusetts counsel to the Funds, in form and
  substance satisfactory to the Acquired Funds and dated the Exchange Date,
  to the effect that (i) each of the Funds is a trust with transferable
  shares duly organized, validly existing and in good standing in conformity
  with the laws of the Commonwealth or Massachusetts; (ii) the MuniYield
  Pennsylvania Common Shares and MuniYield Pennsylvania Series B AMPS to be
  issued pursuant to this Agreement are duly authorized and, upon delivery,
  will be validly issued and outstanding and fully paid and nonassessable by
  MuniYield Pennsylvania, and no shareholder of MuniYield Pennsylvania has
  any preemptive right to subscription or purchase in respect thereof
  (pursuant to the Declaration of Trust or the by-laws of the Funds or
  Massachusetts law, or to the best of such counsel's knowledge, otherwise);
  (iii) this Agreement has been duly authorized, executed and delivered by
  each of the Funds, and represents a valid and binding contract, enforceable
  in accordance with its terms, except as enforceability may be limited by
  bankruptcy, insolvency, reorganization or other similar laws pertaining to
  the enforcement of creditors' rights generally and court decisions with
  respect thereto; provided, such counsel shall express no opinion with
  respect to the application of equitable principles in any proceeding,
  whether at law or in equity; (iv) the execution and delivery of this
  Agreement does not, and the consummation of the Reorganization will not,
  violate any material provisions of Massachusetts law or the Declaration of
  Trust, the by-laws or any agreement (known to such counsel) to which any
  Fund is a party or by which any Fund is bound, except insofar as the
  parties have agreed to amend such provision as a condition precedent to the
  Reorganization; (v) each of the Acquired Funds has the power to sell,
  assign, transfer and deliver the assets transferred by it hereunder and,
  upon consummation of the Reorganization in accordance with the terms of
  this Agreement, each of the Acquired Funds will have duly transferred such
  assets and liabilities in accordance with this Agreement; (vi) to the best
  of such counsel's knowledge, no filing or registration with, or consent,
  approval, authorization or order of any Massachusetts state court or
  governmental authority is required for the consummation by the Funds of the
  Reorganization, except such as have been obtained from the Board of
  Trustees and shareholders of the Funds and such as may be required under
  Massachusetts state securities law; (vii) all actions required to be taken
  by the Funds to authorize this Agreement and to effect the Reorganization
  have been duly authorized by all necessary actions on the part of such
  Fund; and (viii) such opinion is solely for the benefit of the Funds and
  their Trustees and officers. In giving the opinion set forth above, Bingham
  Dana LLP may state that it is relying on certificates of officers of a Fund
  with regard to matters of fact and certain certificates and written
  statements of governmental officials with respect to the good standing of a
  Fund.

    (g) That each Acquired Fund shall have received either (a) a private
  letter ruling from the Internal Revenue Service or (b) an opinion of Brown
  & Wood LLP, to the effect that for Federal income tax purposes (i) the
  transfer by such Acquired Fund of substantially all of its assets to
  MuniYield Pennsylvania in exchange solely for shares of MuniYield
  Pennsylvania Common Shares and MuniYield Pennsylvania Series B AMPS as
  provided in this Agreement will constitute a reorganization within the
  meaning of Section 368(a)(1)(C) of the Code, and the respective Funds will
  each be deemed to be a "party" to a reorganization within the meaning of
  Section 368(b); (ii) in accordance with Section 361(a) of the Code, no gain
  or loss will be recognized to an Acquired Fund as a result of the asset
  transfer solely in exchange for shares of MuniYield Pennsylvania Common
  Shares and MuniYield Pennsylvania Series B AMPS, as the case may be, or on
  the distribution of the MuniYield Pennsylvania shares to shareholders of
  the respective Acquired Fund under Section 361(c)(1); (iii) under Section
  1032 of the Code, no gain or loss will be recognized to MuniYield
  Pennsylvania on the receipt of assets of an Acquired Fund in exchange for
  its shares; (iv) in accordance with Section 354(a)(1) of the Code, no gain
  or loss will be recognized to the shareholders of an Acquired Fund on the
  receipt of Corresponding Shares of MuniYield Pennsylvania in exchange for
  their shares of the Acquired Fund (except to the extent that common
  shareholders receive cash representing an interest in fractional shares of
  MuniYield Pennsylvania Common Shares in the Reorganization); (v) in

                                     II-16



  accordance with Section 362(b) of the Code, the tax basis of and Acquired
  Fund's assets in the hands of MuniYield Pennsylvania will be the same as
  the tax basis of such assets in the hands of the Acquired Fund immediately
  prior to the consummation of the Reorganization; (vi) in accordance with
  Section 358 of the Code, immediately after the Reorganization, the tax
  basis of the shares of MuniYield Pennsylvania received by the shareholders
  of an Acquired Fund in the Reorganization will be equal, in the aggregate,
  to the tax basis of the shares of the Acquired Fund surrendered in
  exchange; (vii) in accordance with Section 1223 of the Code, a
  shareholder's holding period for the shares of MuniYield Pennsylvania will
  be determined by including the period for which such shareholder held the
  Acquired Fund shares exchanged therefor, provided that such shares were
  held as a capital asset; (viii) in accordance with Section 1223 of the
  Code, MuniYield Pennsylvania's holding period with respect to an Acquired
  Fund's assets transferred will include the period for which such assets
  were held by the Acquired Fund; (ix) the payment of cash to common
  shareholders of an Acquired Fund in lieu of fractional shares of MuniYield
  Pennsylvania Common Shares will be treated as though the fractional shares
  were distributed as part of the Reorganization and then redeemed, with the
  result that such shareholders will have short- or long-term capital gain or
  loss to the extent that the cash distribution differs from the
  shareholder's basis allocable to the MuniYield Pennsylvania fractional
  shares; and (x) the taxable year of each Acquired Fund will end on the
  effective date of the Reorganization and pursuant to Section 381(a) of the
  Code and regulations thereunder, MuniYield Pennsylvania will succeed to and
  take into account certain tax attributes of each Acquired Fund, such as
  earnings and profits, capital loss carryovers and method of accounting.

    (h) That all proceedings taken by each of the Funds and its counsel in
  connection with the Reorganization and all documents incidental thereto
  shall be satisfactory in form and substance to the others.

    (i) That the N-14 Registration Statement shall have become effective
  under the 1933 Act, and no stop order suspending such effectiveness shall
  have been instituted or, to the knowledge of MuniYield Pennsylvania, be
  contemplated by the Commission.

    (j) That Acquired Funds shall have received from Deloitte & Touche LLP a
  letter dated within three days prior to the effective date of the N-14
  Registration Statement and a similar letter dated within five days prior to
  the Exchange Date, in form and substance satisfactory to them, to the
  effect that (i) they are independent public accountants with respect to
  MuniYield Pennsylvania within the meaning of the 1933 Act and the
  applicable published rules and regulations thereunder; (ii) in their
  opinion, the financial statements and supplementary information of
  MuniYield Pennsylvania included or incorporated by reference in the N-14
  Registration Statement and reported on by them comply as to form in all
  material respects with the applicable accounting requirements of the 1933
  Act and the published rules and regulations thereunder; and (iii) on the
  basis of limited procedures agreed upon by the Funds and described in such
  letter (but not an examination in accordance with generally accepted
  auditing standards) consisting of a reading of any unaudited interim
  financial statements and unaudited supplementary information of MuniYield
  Pennsylvania included in the N-14 Registration Statement, and inquiries of
  certain officials of MuniYield Pennsylvania responsible for financial and
  accounting matters, nothing came to their attention that caused them to
  believe that (a) such unaudited financial statements and related unaudited
  supplementary information do not comply as to form in all material respects
  with the applicable accounting requirements of the 1933 Act and the
  published rules and regulations thereunder, (b) such unaudited financial
  statements are not fairly presented in conformity with generally accepted
  accounting principles, applied on a basis substantially consistent with
  that of the audited financial statements, or (c) such unaudited
  supplementary information is not fairly stated in all material respects in
  relation to the unaudited financial statements taken as a whole; and (iv)
  on the basis of limited procedures agreed upon by the Funds and described
  in such letter (but not an examination in accordance with generally
  accepted auditing standards), the information relating to MuniYield
  Pennsylvania appearing in the N-14 Registration Statement, which
  information is expressed in dollars (or percentages derived from such
  dollars) (with the exception of performance comparisons, if any), if any,
  has been obtained from the accounting records of MuniYield Pennsylvania or
  from schedules prepared by officials of MuniYield Pennsylvania having
  responsibility for financial and reporting matters and such information is
  in agreement with such records, schedules or computations made therefrom.

                                     II-17



    (k) That the Commission shall not have issued an unfavorable advisory
  report under Section 25(b) of the 1940 Act, nor instituted or threatened to
  institute any proceeding seeking to enjoin consummation of the
  Reorganization under Section 25(c) of the 1940 Act, and no other legal,
  administrative or other proceeding shall be instituted or threatened which
  would materially affect the financial condition of MuniYield Pennsylvania
  or would prohibit the Reorganization.

    (l) That the Acquired Funds shall have received from the Commission such
  orders or interpretations as Brown & Wood LLP, as their counsel, deems
  reasonably necessary or desirable under the 1933 Act and the 1940 Act in
  connection with the Reorganization, provided, that such counsel shall have
  requested such orders as promptly as practicable, and all such orders shall
  be in full force and effect.

10.MuniYield Pennsylvania Conditions.

  The obligations of MuniYield Pennsylvania hereunder shall be subject to the
following conditions:

    (a) That this Agreement shall have been adopted, and the Reorganization
  shall have been approved, by the Board of Trustees and the shareholders of
  each of the Funds as set forth in Section 10(a); and that each of the
  Acquired Funds shall have delivered to MuniYield Pennsylvania a copy of the
  resolution approving this Agreement adopted by such Acquired Fund's Board
  of Trustees, and a certificate setting forth the vote of the shareholders
  of such Acquired Fund obtained, each certified by its Secretary.

    (b) That each Acquired Fund shall have furnished to MuniYield
  Pennsylvania a statement of its assets, liabilities and capital, with
  values determined as provided in Section 6 of this Agreement, together with
  a schedule of investments with their respective dates of acquisition and
  tax costs, all as of the Valuation Time, certified on such Fund's behalf by
  its President (or any Vice President) and its Treasurer, and a certificate
  signed by such Fund's President (or any Vice President) and its Treasurer,
  dated as of the Exchange Date, certifying that as of the Valuation Time and
  as of the Exchange Date there has been no material adverse change in the
  financial position of the Acquired Fund since the date of such Fund's most
  recent Annual Report or Semi-Annual Report, as applicable, other than
  changes in the Acquired Fund Investments since that date or changes in the
  market value of the Acquired Fund Investments.

    (c) That each Acquired Fund shall have furnished to MuniYield
  Pennsylvania a certificate signed by such Fund's President (or any Vice
  President) and its Treasurer, dated the Exchange Date, certifying that as
  of the Valuation Time and as of the Exchange Date all representations and
  warranties of the Acquired Fund made in this Agreement are true and correct
  in all material respects with the same effect as if made at and as of such
  dates and the Acquired Fund has complied with all of the agreements and
  satisfied all of the conditions on its part to be performed or satisfied at
  or prior to such dates.

    (d) That each Acquired Fund shall have delivered to MuniYield
  Pennsylvania a letter from Deloitte & Touche LLP, dated the Exchange Date,
  stating that such firm has performed a limited review of the Federal, state
  and local income tax returns of the Acquired Fund for the period ended
  October 31, 1999 (for MuniVest Pennsylvania) and September 30, 1999 (for
  MuniHoldings Pennsylvania) (which returns originally were prepared and
  filed by the Acquired Fund), and that based on such limited review, nothing
  came to their attention which caused them to believe that such returns did
  not properly reflect, in all material respects, the Federal, state and
  local income taxes of the Acquired Fund for the period covered thereby; and
  that for the period from November 1, 1999 (for MuniVest Pennsylvania) and
  October 1, 1999 (for MuniHoldings Pennsylvania), to and including the
  Exchange Date and for any taxable year of the Acquired Fund ending upon the
  liquidation of that Acquired Fund, such firm has performed a limited review
  to ascertain the amount of applicable Federal, state and local taxes, and
  has determined that either such amount has been paid or reserves have been
  established for payment of such taxes, this review to be based on unaudited
  financial data; and that based on such limited review, nothing has come to
  their attention which caused them to believe that the taxes paid or
  reserves set aside for payment of such taxes were not adequate in all
  material respects for the satisfaction of Federal, state and local taxes
  for the period from November 1, 1999 (for MuniVest Pennsylvania) and
  October 1, 1999 (for MuniHoldings Pennsylvania), to and including the
  Exchange Date and for any taxable year of that Acquired Fund, ending upon
  the liquidation of such fund or that such fund would not qualify as a
  regulated investment company for Federal income tax purposes for the tax
  years in question.

  Dana LLP, as Massachusetts counsel to the Funds, in form and substance

  such other matters as MuniYield Pennsylvania reasonably may deem necessary

  Pennsylvania, to the effect that (i) they are independent public
  accountants with respect to each of the Acquired Funds within the meaning
  of the 1933 Act and the applicable published rules and regulations
  thereunder; (ii) in their opinion, the financial statements and
  supplementary information of each Acquired Fund included or incorporated by
  reference in the N-14 Registration Statement and reported on by them comply
  as to form in all material respects with the applicable accounting
  requirements of the 1933 Act and the published rules and regulations
  thereunder; (iii) on the basis of limited procedures agreed upon by the
  Funds and described in such letter (but not an examination in accordance
  with generally accepted auditing standards) consisting of a reading of any
  unaudited interim financial statements and unaudited supplementary
  information of the Acquired Fund included in the N-14 Registration
  Statement, and inquiries of certain officials of the Acquired Fund
  responsible for financial and accounting matters, nothing came to their
  attention that caused them to believe that (a) such unaudited financial

  to form in all material respects with the applicable accounting
  requirements of the 1933 Act and the published rules and regulations
  thereunder, (b) such unaudited financial statements are not fairly
  presented in conformity with generally accepted accounting principles,
  applied on a basis substantially consistent with that of the audited

  not fairly stated in all material respects in relation to the unaudited
  financial statements taken as a whole; and (iv) on the basis of limited
  procedures agreed upon by the Funds and described in such letter (but not

  administrative or other proceeding shall be instituted or threatened which
  would materially affect the financial condition of any Acquired Fund or
  would prohibit the Reorganization.

                                     II-19



    (m) That MuniYield Pennsylvania shall have received from the Commission
  such orders or interpretations as Brown & Wood LLP, as counsel to MuniYield
  Pennsylvania, deems reasonably necessary or desirable under the 1933 Act

hereof, the same shall become void and have no further effect, and there shall
not be any liability on the part of any Fund or persons who are their
Trustees, trustees, officers, agents or shareholders in respect of this
Agreement.

  (d) At any time prior to the Exchange Date, any of the terms or conditions

officer, Trustee, trustee, agent or shareholder so acts or to its
shareholders, to which that officer, Trustee, trustee, agent or shareholder
otherwise would be subject by reason of willful misfeasance, bad faith, gross
negligence, or reckless disregard of the duties in the conduct of such office.

                                     II-20

the Funds unless such terms and conditions shall result in a change in the
method of computing the number of shares of MuniYield Pennsylvania Common
Shares and MuniYield Pennsylvania Series B AMPS to be issued to the Acquired
Funds, as applicable, in which event, unless such terms and conditions shall
have been included in the proxy solicitation materials furnished to the
shareholders of the Funds prior to the meetings at which the Reorganization
shall have been approved, this Agreement shall not be consummated and shall
terminate unless the Funds promptly shall call a special meeting of
shareholders at which such conditions so imposed shall be submitted for
approval.

12.Indemnification.

  (a) Each Acquired Fund hereby severally agrees to indemnify and hold
MuniYield Pennsylvania harmless from all loss, liability and expenses
(including reasonable counsel fees and expenses in connection with the contest

deficiencies or otherwise, based upon a claim or claims against such Acquired
Fund which were omitted or not fairly reflected in the financial statements to
be delivered to MuniYield Pennsylvania in connection with the Reorganization;
(ii) any representations or warranties made by such Acquired Fund in this
Agreement should prove to be false or erroneous in any material respect; (iii)

circumstances under which they were made, not misleading, except with respect
to (iv)(a) and (b) herein insofar as such claim is based on written
information furnished to the Acquired Funds by MuniYield Pennsylvania.

  (b) MuniYield Pennsylvania hereby agrees to indemnify and hold each Acquired
Fund harmless from all loss, liability and expenses (including reasonable
counsel fees and expenses in connection with the contest of any claim) which
such Acquired Fund may incur or sustain by reason of the fact that (i) any
representations or warranties made by MuniYield Pennsylvania in this Agreement
should prove false or erroneous in any material respect, (ii) any covenant of
MuniYield Pennsylvania has been breached in any material respect, or (iii) any
claim is made alleging that (a) the N-14 Registration Statement included any
untrue statement of a material fact or omitted to state any material fact
required to be stated therein or necessary to make the statements therein, not
misleading or (b) the Joint Proxy Statement and Prospectus delivered to
shareholders of the Funds and forming a part of the N-14 Registration
Statement included any untrue statement of a material fact or omitted to state
any material fact necessary to make the statements therein, in the light of
the circumstances under which they were made, not misleading, except with
respect to (iii)(a) and (b) herein insofar as such claim is based on written
information furnished to MuniYield Pennsylvania by the Acquired Fund seeking
indemnification.

  (c) In the event that any claim is made against MuniYield Pennsylvania in
respect of which indemnity may be sought by MuniYield Pennsylvania from an
Acquired Fund under Section 12(a) of this Agreement, or in the event that any
claim is made against an Acquired Fund in respect of which indemnity may be
sought by an Acquired Fund from MuniYield Pennsylvania under Section 12(b) of
this Agreement, then the party seeking indemnification (the "Indemnified
Party"), with reasonable promptness and before payment of such claim, shall
give written notice of such claim to the other party (the "Indemnifying
Party"). If no objection as to the validity of the claim is made in writing to
the Indemnified Party by the Indemnifying Party within thirty (30) days after
the giving of notice hereunder, then the Indemnified Party may pay such claim
and shall be entitled to reimbursement therefor, pursuant to this Agreement.
If, prior to the termination of such thirty-day period, objection in writing
as to the validity of such claim is made to the Indemnified Party, the
Indemnified Party shall

                                     II-21


withhold payment thereof until the validity of such claim is established (i)
to the satisfaction of the Indemnifying Party, or (ii) by a final
determination of a court of competent jurisdiction, whereupon the Indemnified
Party may pay such claim and shall be entitled to reimbursement thereof,
pursuant to this Agreement, or (iii) with respect to any tax claims, within
seven (7) calendar days following the earlier of (A) an agreement between
MuniYield Pennsylvania and the Acquired Fund seeking indemnification that an
indemnity amount is payable, (B) an assessment of a tax by a taxing authority,
or (C) a "determination" as defined in Section 1313(a) of the Code. For
purposes of this Section 13, the term "assessment" shall have the same meaning
as used in Chapter 63 of the Code and Treasury Regulations thereunder, or any
comparable provision under the laws of the appropriate taxing authority. In
the event of any objection by the Indemnifying Party, the Indemnifying Party
promptly shall investigate the claim, and if it is not satisfied with the
validity thereof, the Indemnifying Party shall conduct the defense against
such claim. All costs and expenses incurred by the Indemnifying Party in
connection with such investigation and defense of such claim shall be borne by
it. These indemnification provisions are in addition to, and not in limitation
of, any other rights the parties may have under applicable law.

13.Other Matters.

                 ECONOMIC AND OTHER CONDITIONS IN PENNSYLVANIA

  The following information is a brief summary of factors affecting the
economy of the Commonwealth of Pennsylvania and does not purport to be a
complete description of such factors. Other factors will affect issuers. The
summary is based upon one or more of the most recent publicly available
offering statements relating to debt offerings of Pennsylvania issuers. The
Funds have not independently verified the information.

  Many factors affect the financial condition of the Commonwealth of
Pennsylvania (also referred to herein as the "Commonwealth") and its political
subdivisions, such as social, environmental and economic conditions, many of
which are not within the control of such entities. Pennsylvania and certain of
its counties, cities and school districts and public bodies (most notably the
City of Philadelphia, sometimes referred to herein as the "City") have from
time to time in the past encountered financial difficulties which have
adversely affected their respective credit standings. Such difficulties could
affect outstanding obligations of such entities, including obligations held by
the Fund.

  The General Fund, the Commonwealth's largest fund, receives all tax
revenues, non-tax revenues and Federal grants and entitlements that are not
specified by law to be deposited elsewhere. The majority of the Commonwealth's
operating and administrative expenses are payable from the General Fund. Debt
service on all bonded indebtedness of the Commonwealth, except that issued for
highway purposes or for the benefit of other special revenue funds, is payable
from the General Fund.

  The five-year period ending with fiscal year 1998 was a time of economic
growth with modest growth rates at the beginning of the period and faster
increases during the most recent years. Throughout the period, inflation has
remained relatively low, helping to restrain expenditure growth. Favorable
economic conditions have helped total revenues and other sources rise at an
annual average of 4.2% rate during the five-year period. The annual growth
rate for taxes of 4.3% almost matched the total revenue rate. Expenditures and
other uses during the fiscal 1994 through fiscal 1998 period rose at a 3.8%
average rate, led by a 10.2% average increase for protection of person and
property costs.

  On a generally accepted accountable principles ("GAAP") basis, revenues and
other sources from fiscal 1994 through fiscal 1998 increased by an average 5%
annually. Expenditures and other uses during this period rose at an average
annual rate of 5%.

  The fund balance at June 30, 1998 (determined on a "Generally Accepted
Accounting Principles" basis) totaled $1,958.9 million, a $594 million
increase over the $1,364.9 million balance at June 30, 1997.

  The unappropriated balance of Commonwealth revenues increased during the
1997 fiscal year by $432.9 million to $591.4 million (prior to reserves for
transfer to the Tax Stabilization Reserve Fund) at the close of the fiscal
year. Higher than estimated revenues and slightly lower expenditures than
budgeted caused the increase. Transfers to the Tax Stabilization Reserve Fund
for fiscal 1997 operations were $188.7 million representing the normal 15% of
the ending unappropriated balance, plus an additional $100 million authorized
by the General Assembly when it enacted the fiscal 1998 budget.

  Commonwealth revenues (prior to tax refunds) during the fiscal year totaled
$17,320.6 million, $576.1 million (3.4%) above the estimate made at the time
the budget was enacted. Revenue from taxes was the largest contributor to
higher than estimated receipts. Tax revenue in fiscal 1997 grew 6.1% over tax
revenues in fiscal 1996. This rate of increase is not adjusted for legislated
tax reductions that affected receipts during both of those fiscal years and
therefore understates the actual underlying rate of growth of tax revenue
during fiscal 1997. Non-tax revenues were $19.8 million (5.8%) over estimate
mostly due to higher than anticipated interest earnings.


                                     III-1



  Expenditures from Commonwealth revenues (excluding pooled financing
expenditures) during fiscal 1997 totaled $16,347.7 million. Total expenditures
represent an increase over fiscal 1996 expenditures of 1.7%. Lapses of
appropriation authority during the fiscal year totaled $200.6 million compared
to an estimate of $100 million. The higher amount of appropriation lapses was
used to support $79.8 million in fiscal 1997 supplemental appropriations over
those proposed in February 1997. Supplemental appropriations for fiscal 1997
totaled $169.3 million.

  For GAAP purposes, assets increased $563.4 million and liabilities declined
$166.3 million to produce a $729.7 million increase in the fund balance at
June 30, 1997. Total revenues and other sources rose 3.5% for fiscal 1997. An
increase of 5.5% in tax revenue aided by an improving state economy was
partially offset by a $175.2 million decline in intergovernmental revenues.
Expenditures and other uses increased by 1% for the fiscal year.

  Operations during the 1998 fiscal year increased the unappropriated balance
of Commonwealth revenues during that period by $86.4 million to $488.7 million
at June 30, 1998 (prior to reserves for transfer to the Tax Stabilization
Reserve Fund). Higher than estimated revenues, offset in part by increased
reserves for tax refunds, and by slightly lower expenditures than budgeted
were responsible for the increase. Transfers to the Tax Stabilization Reserve
Fund for fiscal 1998 operations total $223.3 million consisting of $73.3
million representing the required transfer of fifteen percent of the ending
unappropriated surplus balance, plus an additional $150 million authorized by
the General Assembly when it enacted the fiscal 1999 budget. With these
transfers, the balance in the Tax Stabilization Reserve Fund exceeds $668
million and represent 3.7% of fiscal 1998 revenues.

  Commonwealth revenues (prior to tax refunds) during the fiscal year totaled
$18,123.2 million, $676.1 million (3.9%) above the estimate made at the time
the budget was enacted. Tax revenue received in fiscal 1998 grew 4.8% over tax
revenues received during fiscal 1997. This rate of increase includes the
effect of legislated tax reductions that affected receipts during both fiscal
years and therefore understates the actual underlying rate of growth of tax
revenue during fiscal 1998. Receipts from the personal income tax produced the
largest single component of higher revenues during fiscal 1998.

  Expenditures from all fiscal 1998 appropriations of Commonwealth revenues
totaled $17,229.8 million (excluding pooled financing expenditures and net of
current year lapses). This amount represents an increase of 4.5% over fiscal
1997 appropriation expenditures. Lapses of appropriation authority during the
fiscal year totaled $161.8 million including $58.8 million from fiscal 1998
appropriations. These appropriation lapses were used to fund $120.5 million of
supplemental fiscal 1998 appropriations.

  Reserves established during fiscal 1998 for tax refunds totaled $910
million. This amount is a $370 million increase over tax refund reserves for
fiscal 1997 representing an increase of 68.5%. The fiscal 1998 amount includes
a one-time addition intended to fund all fiscal 1998 tax refund liabilities,
including that portion to be paid during fiscal 1999. In prior fiscal years,
tax refunds generally were budgeted for the year in which the disbursement was
anticipated to occur. This change in the recognition of tax refund liabilities
on a budgetary basis helped eliminate the negative difference between the
budgetary basis unappropriated balance and the GAAP basis unreserved-
undesignated balance for the 1998 fiscal year.

  For GAAP purposes, assets increased $705.1 million and liabilities rose by
$111.1 million during the fiscal year. These changes contributed to a $310.3
million dollar rise in the undesignated-unreserved balance for June 30, 1998
to $497.6 million, the highest level achieved since audited GAAP reporting was
instituted in 1984. Fiscal 1998 total revenues and other sources rose 4.3%.
Expenditures and other uses during fiscal 1998 rose by 4.5%.

  The 1999 fiscal year ended with an unappropriated surplus (prior to the
transfer to the Tax Stabilization Reserve Fund) of $702.9 million, an increase
of $214.2 million from June 30, 1998. Transfers to the Tax Stabilization
Reserve Fund total $255.4 million for fiscal year 1999 consisting of $105.4
million representing the

                                     III-2



statutory 15% of the fiscal year-end unappropriated surplus and an additional
$150 million from the unappropriated surplus authorized by the General
Assembly. The $447.5 million balance of the unappropriated surplus was carried
over to fiscal year 2000. The higher unappropriated surplus was generated by
tax revenues that were $712.0 million (3.9%) above estimate and $61.0 million
of non-tax revenue (18.4%) above estimate. Higher than anticipated
appropriation lapses also contributed to the higher surplus. A portion of the
higher revenues and appropriation lapses were used for supplemental fiscal
1999 appropriations totaling $357.8 million. These supplemental appropriations
represent expected one-time obligations. Including the supplemental
appropriations and net of appropriation lapses, expenditures for fiscal 1999
totaled $18,144.9 million, a 5.9% increase over expenditures during fiscal
1998.

  Appropriations enacted for fiscal 1999 when the budget was originally
adopted were 4.1% ($713.2 million) above the appropriations enacted for fiscal
1998 (including supplemental appropriations).

  Reserves for tax refunds for fiscal 1999 were raised during the fiscal year
to $644.0 million, a $39.2 million increase over the budget as enacted.
Reserves for tax refunds for fiscal 1999 are $266.0 million below the reserve
established for fiscal 1998. The fiscal 1998 amount includes a one-time
addition intended to fund all fiscal 1998 tax refund liabilities, including
that portion to be paid during fiscal 1999.

  The General Fund budget for the 2000 fiscal year was approved by the General
Assembly in May 1999. The adopted budget includes estimated spending of
$19,061.5 million and estimated revenues (net of estimated tax refunds and
enacted tax changes) of $18,699.9 million. Funds to cover the $361.6 million
difference between estimated revenues and projected spending will be obtained
from a draw down of the projected fiscal 1999 year-end balance. The level of
proposed spending represents an increase of 3.8% over revised spending
authorized for fiscal 1999 of $18,367.5 million. Enacted tax changes effective
for fiscal 2000 total a net reduction of $380.2 million for the General Fund.

  The estimate of Commonwealth revenues for fiscal year 1999 is based on an
economic forecast for real gross domestic product to grow at a 1.4% rate from
the second quarter of 1999 to the second quarter of 2000. Growth of real gross
domestic product is expected to be restrained by a slowing of the rate of
consumer spending to a level consistent with personal income gains and by
smaller gains in business investment in response to falling capacity
utilization and profits. Slowing economic growth is expected to cause the
unemployment rate to rise through the fiscal year but inflation is expected to
remain moderate. Trends for the Pennsylvania economy are expected to maintain
their close association with national economic trends. Personal income growth
is anticipated to remain slightly below that of the U.S. while the
Pennsylvania unemployment rate is anticipated to be very close to the national
rate.

  Commonwealth revenues (excluding the estimated cost of the enacted tax
reductions) are projected to increase by 2.8% over revised fiscal 1999
receipts. Appropriations from Commonwealth funds are budgeted to increase by
3.8% over revised fiscal 1999 appropriations.

  According to a Pennsylvania Department of Revenue News Release, dated
September 30, 1999, the state collected $1.8 billion in General Fund revenues
in September, 1999, $55.2 million (3.2%) more than anticipated. Fiscal years-
to-date General Fund collections total $4.3 billion, which is $76 million
(2.1%) more than anticipated.

  Pennsylvania has historically been identified as a heavy industry state
although that reputation has changed over the last thirty years as the coal,
steel and railroad industries declined and the Commonwealth's business
environment readjusted to reflect a more diversified industrial base. This
economic readjustment was a direct result of a long-term shift in jobs,
investment and workers away from the northeast part of the nation. Currently,
the major sources of growth in Pennsylvania are in the service sector,
including trade, medical and the health services, education and financial
institutions.

                                     III-3



  Nonagricultural employment in Pennsylvania over the ten year period that
ended in 1998 increased at an annual rate of 0.75%. This compares to a 0.29%
rate for the Middle Atlantic region and a 1.72% rate for the United States as
a whole during the period 1989 through 1998. For the five years ended with
1998, employment in the Commonwealth has increased 7.0%. The growth in
employment during this period is higher than the 2.7% growth in the Middle
Atlantic region. The unemployment rate in Pennsylvania for August, 1999 stood
at a seasonably adjusted rate of 4.5%. The seasonably adjusted national
unemployment rate for August, 1999 was 4.2%.

  The current Constitutional provisions pertaining to Commonwealth debt permit
the issuance of the following types of debt: (i) debt to suppress insurrection
or rehabilitate areas affected by disaster, (ii) electorate-approved debt,
(iii) debt for capital projects subject to an aggregate debt limit of 1.75
times the annual average tax revenues of the preceding five fiscal years and
(iv) tax anticipation notes payable in the fiscal year of issuance. All debt
except tax anticipation notes must be amortized in substantial and regular
amounts.

  Debt service on all bonded indebtedness of Pennsylvania, except that issued
for highway purposes or the benefit of other special revenue funds, is payable
from Pennsylvania's General Fund, which receives all Commonwealth revenues
that are not specified by law to be deposited elsewhere. As of June 30, 1999,
the Commonwealth had $4,924.5 million of general obligation debt outstanding.

  Other state-related obligations include "moral obligations." Moral
obligation indebtedness may be issued by the Pennsylvania Housing Finance
Agency (the "PHFA"), a state-created agency which provides financing for
housing for lower and moderate income families, and The Hospitals and Higher
Education Facilities Authority of Philadelphia, a municipal authority
organized by the City of Philadelphia to, among other things, acquire and
prepare various sites for use as intermediate care facilities for the mentally
retarded. PHFA's bonds, but not its notes, are partially secured by a capital
reserve fund required to be maintained by PHFA in an amount equal to the
maximum annual debt service on its outstanding bonds in any succeeding
calendar year. PHFA is not permitted to borrow additional funds as long as any
deficiency exists in the capital reserve fund.

  The Commonwealth, through several of its departments and agencies, leases
real property and equipment. Some of those leases and their respective lease
payments are, with the Commonwealth's approval, pledged as security for debt
obligations issued by certain public authorities or other entities within the
state. All lease payments payable by Commonwealth departments and agencies are
subject to and dependent upon an annual spending authorization approved
through the Commonwealth's annual budget process. The Commonwealth is not
required by law to appropriate or otherwise provide monies from which the
lease payments are to be made. The obligations to be paid from such lease
payments are not bonded debt of the Commonwealth.

  Certain Commonwealth-created organizations have statutory authorization to
issue debt for which Commonwealth appropriations to pay debt service thereon
are not required. The debt of these organizations is funded by assets of, or
revenues derived from, the various projects financed and is not a statutory or
moral obligation of the Commonwealth. Some of these agencies, however, are
indirectly dependent on Commonwealth operating appropriations. In addition,
the Commonwealth may choose to take action to financially assist these
organizations. The Commonwealth also maintains pension plans covering all
state employees, public school employees and employees of certain state-
related organizations.

  The Pennsylvania Intergovernmental Cooperation Authority (the "PICA") was
created by Commonwealth legislation in 1991 to assist Philadelphia in
remedying fiscal emergencies. PICA is designed to provide assistance through
the issuance of funding debt and to make factual findings and recommendations
to Philadelphia concerning its budgetary and fiscal affairs. At this time,
Philadelphia is operating under a five year fiscal plan approved by PICA on
June 15, 1999.

  No further bonds are to be issued by PICA for the purpose of financing a
capital project or deficit as the authority for such bond sales expired
December 31, 1994. PICA's authority to issue debt for the purpose of financing
a cash flow deficit expired on December 31, 1996. Its ability to refund
existing outstanding debt is unrestricted. PICA had $1,014.1 million in
Special Revenue bonds outstanding as of June 30, 1999.

                                     III-4


  There is various litigation pending against the Commonwealth, its officers
and employees. In 1978, the Pennsylvania General Assembly approved a limited
waiver of sovereign immunity. Damages for any loss are limited to $250,000 for
each person and $1 million for each accident. The Supreme Court held that this
limitation is constitutional. Approximately 3,500 suits against the
Commonwealth remain open.

  The following are among the cases with respect to which the Office of
Attorney General and the Office of General Counsel have determined that an
adverse decision may have a material effect on government operations of the
Commonwealth:

 Dom Giordano v. Tom Ridge, Governor, et al.

  In February 1999, Dom Giordano, filed a petition for review requesting the
Commonwealth Court declare that Chapter 5 (relating to sports facilities
financing) of the Capital Facilities Debt Enabling Act ("the Act") violates
the Pennsylvania Constitution. The Commonwealth Court dismissed the
petitioner's action with prejudice. The petitioner has appealed the
Commonwealth Court's ruling to the Supreme Court.

 County of Allegheny v. Commonwealth of Pennsylvania

  In December 1987, the Supreme Court of Pennsylvania held in County of
Allegheny v. Commonwealth of Pennsylvania, that the statutory scheme for
county funding of the judicial system is in conflict with the Pennsylvania
Constitution. However, the Supreme Court of Pennsylvania stayed its judgment
to afford the General Assembly an opportunity to enact appropriate funding
legislation consistent with its opinion and ordered that the prior system of
county funding shall remain in place until this is done.

  The Court appointed a special master to devise and submit a plan for
implementation. The Interim Report of the Master recommended a four phase
transition to state funding of a unified judicial system, during each of which
specified court employees would transfer into the state payroll system. On
April 22, 1998, the General Assembly enacted the General Appropriation Act of
1998, including an appropriation to the Supreme Court of approximately $12
million for funding county court administrators. This appropriation was
designed to enable the Commonwealth to implement Phase I. Release of the
funding was delayed until substantive legislation could be enacted to
facilitate the employees' transfer to State employment. A similar
appropriation was made by the General Appropriation Act of 1999. Thereafter,
on June 22, 1999, the Governor approved Act 1999-12 under which approximately
165 county-level court administrators are to become employees of the
Commonwealth. Act 12 also triggered the release of the appropriations that had
been made for this purpose in 1998 and 1999.

 Bank Shares Tax Litigation

  In November 1989, Fidelity Bank, N.A. ("Fidelity") filed a declaratory
judgment action in the Commonwealth Court of Pennsylvania in which Fidelity
raised various challenges to the constitutional validity of the Amended Bank
Shares Act (Act No. 1989-21) and related legislation. In 1995 Fidelity and the
Commonwealth agreed to a settlement of the issues raised by Fidelity. Under a
separate Settlement Agreement the Commonwealth settled with the intervening
banks, referred to as "New Banks," in connection with issues concerning the
New Bank Tax Credit Law which were raised in an appeal to the Pennsylvania
Supreme Court.

  Other banks have also filed petitions that are currently pending with the
Commonwealth Court. One of these banks, Royal Bank of Pennsylvania, filed a
Stipulation of Facts with the Court and in effect proceeded forward on behalf
of all the other banks. These appeals raise the issues that were advanced by
Fidelity, although not brought to final resolution by the Pennsylvania Supreme
Court. In January 1998, a panel of the Commonwealth Court ruled in favor of
the Commonwealth, finding no constitutional violation. Royal Bank filed
exceptions. On July 30, 1998, the Commonwealth Court, en banc, denied those
exceptions. On May 25, 1999, the Pennsylvania Supreme Court affirmed per
curium the Commonwealth Court's decision and order. No petition for certiorari
was filed. Therefore, the Royal Bank litigation has ended. However, the vast
majority of the remaining banks have exceptions pending before the
Commonwealth Court or appeals pending before the Pennsylvania Supreme Court.

                                     III-5



 Pennsylvania Association of Rural and Small Schools (PARSS) v. Ridge

  In 1991, an association of rural and small schools and several parties filed
a lawsuit against the Governor and Secretary of Education, challenging the
constitutionality of the Commonwealth system for funding local school
districts. The litigation consists of two parallel cases, one in the
Commonwealth Court of Pennsylvania and one in the United States District Court
for the Middle District of Pennsylvania. The federal court case has been
indefinitely stayed pending resolution of the state court case.

  Commonwealth Court held that Pennsylvania's system for funding public
schools is constitutional under both the education clause and the equal
protection clause of the Pennsylvania Constitution. On October 1, 1999, the
Pennsylvania Supreme Court affirmed the Commonwealth Court decision. The
parallel federal action remains pending.

 Pennsylvania Human Relations Commission v. School District of Philadelphia,
 et al. v. Commonwealth of Pennsylvania, et al.

  In November 1995, the Commonwealth of Pennsylvania and the Governor of
Pennsylvania, along with the City of Philadelphia and the Mayor of
Philadelphia, were joined as additional respondents in an enforcement action
commenced in Commonwealth Court in 1973 by the Pennsylvania Human Relations
Commission against the School District of Philadelphia pursuant to the
Pennsylvania Human Relations Act. The enforcement action was pursued to remedy
unintentional conditions of segregation in the public schools of Philadelphia.
The Commonwealth and the City were joined in the "remedial phase" of the
proceeding "to determine their liability, if any, to pay additional costs
necessary to remedy the unlawful conditions found to exist in the Philadelphia
public schools."

  In February 1996, the School District of Philadelphia filed a third-party
complaint against the Commonwealth of Pennsylvania asking Commonwealth Court
to require the Commonwealth to supply such funding as is necessary for full
compliance with the remedial orders of the Commonwealth Court. In addition, a
group of interveners filed a third-party complaint against the Commonwealth of
Pennsylvania and the City of Philadelphia requesting Commonwealth Court to
require the Commonwealth and the City to supply such additional funding as is
necessary for the District to comply with the orders.

  On April 30, 1996, Commonwealth Court Judge Doris A. Smith overruled the
Commonwealth's and City's preliminary objections seeking dismissal of the
claims against them. The Commonwealth and the City thereafter filed answers to
the complaints, asserting numerous defenses. The Commonwealth also asserted a
cross-claim against the City of Philadelphia claiming that if any party is
liable, sole liability rests with the City; in the alternative, the
Commonwealth argued that if it is held to be liable, it has a right of
indemnity of contribution against the City.

  The Supreme Court of Pennsylvania assumed extraordinary plenary
jurisdiction. In May 1999, the Supreme Court of Pennsylvania directed that the
Commonwealth, the Governor, the City of Philadelphia and the Mayor of
Philadelphia be dismissed from the case. The Court then remanded the original
matter--an enforcement action by the Pennsylvania Human Relations Commission
against the School District of Philadelphia to eliminate racial de facto
segregation in the public system--to Commonwealth Court for further
proceedings. No appeal has been filed or is expected. Thus, the Commonwealth
and the Governor are no longer parties to this case.


 Ridge v. State Employees' Retirement Board

  In 1993 and in 1995, Joseph H. Ridge, a former judge of the Allegheny Court
of Common Pleas, filed suit in the Commonwealth Court alleging that the use of
gender distinct actuarial factors for benefits based upon his

                                     III-6



pre-August 1, 1983 service violates the equal protection and equal rights
clauses of the Pennsylvania Constitution. The lawsuit requests that the
petitioner's benefits be "topped up" to equal those that a similarly situated
female would be receiving. Due to the constitutional nature of the claim, it
is possible that a decision adverse to the Retirement Board would be
applicable to other members of the State Employees' Retirement System and
Public School Employees' Retirement System. The Commonwealth Court granted the
Retirement Board's preliminary objection to Judge Ridge's claims for punitive
damages, attorney's fees and compensatory damages (other than a recalculation
of his pension benefits should he prevail). In 1996, the Commonwealth Court
heard oral arguments en banc on Judge Ridge's motion for judgment on the
pleadings. On February 13, 1997, the Commonwealth Court denied Judge Ridge's
motion for judgment on the pleadings. The case is currently in discovery.

 Yesenia Marrerro, et al. v. Commonwealth, et al.

  In February 1997, five residents of the City of Philadelphia, on their own
behalf, and on behalf of their school-age children, joined by the City of
Philadelphia, the School District of Philadelphia, and two non-profit
organizations, filed in the Commonwealth Court a civil action for declaratory
judgment against the Commonwealth of Pennsylvania, the General Assembly of
Pennsylvania, the presiding officers of the General Assembly, the Governor of
Pennsylvania, the State Board of Education, the Department of Education, and
the Secretary of Education, claiming, among other things, that the statutory
education financing system is unconstitutional as applied to the School
District of Philadelphia and the system of funding public education violates
the constitutional mandate to provide a thorough and efficient system of
education in the City of Philadelphia. The lawsuit also alleges that the
scheme for financing public education precludes the Commonwealth from
providing the constitutionally required "thorough and efficient system of
public education" in the circumstances faced by the School District of
Philadelphia, and that the defendants have failed to provide the School
District of Philadelphia with resources and other assistance necessary to
provide all of its students with the quality of education to which they are
constitutionally entitled. In March 1998, Commonwealth Court dismissed the
case on the grounds that the issues presented are not justiciable. On October
1, 1999 the Supreme Court of Pennsylvania affirmed the Commonwealth Court's
order.

 Powell v. Ridge

  In March 1998, several residents of the City of Philadelphia on behalf of
themselves and their school-aged children, along with the School District of
Philadelphia, the Philadelphia Superintendent of Schools, the chairman of the
Philadelphia Board of Education, the City of Philadelphia, the Mayor of
Philadelphia, and several membership organizations interested in the
Philadelphia public schools, brought suit in the United States District Court
for the Eastern District of Pennsylvania against the Governor, the Secretary
of Education, the chairman of the State Board of Education, and the State
Treasurer. The plaintiffs claim that the Commonwealth's system for funding
public schools has the effect of discriminating on the basis of race and
violates Title VI of the Civil Rights Act of 1964. The plaintiffs asked the
court to declare the funding system to be illegal, to enjoin the defendants
from violating the regulation in the future and to award counsel fees and
costs.

  The Philadelphia Federation of Teachers intervened on the side of the
plaintiffs, while several leaders of the Pennsylvania General Assembly
intervened on the side of the defendants. In addition, the U.S. Department of
Justice intervened to defend against a claim made by the legislator
intervenors that a statute waiving states' immunity under the Eleventh
Amendment to the U.S. Constitution for Title VI claims is unconstitutional.

  The District Court found that the plaintiffs had failed to state a claim
under the Title VI regulation at issue or under 42 U.S.C. (S)1983 and
dismissed the action in its entirety with prejudice. The plaintiffs appealed.
In August 1999, the U.S. Court of Appeals for the Third Circuit reversed the
District Court's dismissal of the action and remanded the case for further
proceedings including the filing of an answer. The defendants and legislator
intervenors have filed petitions for writ of certiorari with the U.S. Supreme
Court.


                                     III-7


 Rite Aid of Pennsylvania, Inc. v. Houstoun

  In March 1997, Rite Aid of Pennsylvania, Inc. (Rite Aid) filed in the U.S.
District Court for the Eastern District of Pennsylvania a civil action against
the Secretary of Public Welfare (Secretary). In its complaint, Rite Aid
alleged that in promulgating regulations on October 1, 1995 governing payment
rates for prescription drugs and related services provided to recipients of
benefits under the Pennsylvania Medical Assistance Program (Medicaid), the
Secretary violated various provisions of Title XIX of the Social Security Act
(commonly known as the Medicaid Act) and regulations of the U.S. Department of
Health and Human Services, as well as provisions of state law and federal
constitutional due process.

  In August 1998, the District Court declared that the pharmacy reimbursement
rates made effective after October 1, 1995, were adopted by the Secretary in
violation of section 1396(a)(30)(A) of the Medicaid Act and enjoined the
Secretary from using those rates to reimburse for any prescription drugs and
related services provided to Medicaid recipients on and after October 1, 1998.
The Court held that the Secretary acted arbitrarily and capriciously by
failing to consider whether the revised rates were consistent with the
statutory standards of efficiency, economy, and quality of care.

  The Secretary appealed the District Court's orders. On March 22, 1999, the
U.S. Court of Appeals for the Third Circuit reversed the District Courts'
order and remanded the case for further proceedings. The Court of Appeals held
that the Secretary had not violated the Medicaid Act in adopting rates in
1995, but the Court remanded the case to allow the plaintiffs to pursue any
claim which they might have that the rates substantially do not satisfy the
statutory standard prescribed by 42 U.S.C. (S)1396(a)(30)(A).

  The case is pending in the District Court. No substantial proceedings have
occurred since the remand. In addition, a case raising analogous state law
issues is pending in Commonwealth Court.

  Pennsylvania general obligation bonds are currently rated AA by Standard &
Poor's, AA by Fitch and Aa3 by Moody's. There can be no assurance that the
economic conditions on which these ratings are based will continue or that
particular bond issues will not be adversely affected by changes in economic
or political conditions.

                                                                     EXHIBIT IV

                RATINGS OF MUNICIPAL BONDS AND COMMERCIAL PAPER

Description of Moody's Investors Service, Inc.'s ("Moody's") Municipal Bond
Ratings

  "Aaa"-Bonds which are rated Aaa are judged to be of the best quality. They
carry the smallest degree of investment risk and are generally referred to as
"gilt edge." Interest payments are protected by a large or by an exceptionally
stable margin and principal is secure. While the various protective elements
are likely to change, such changes can be visualized and are most unlikely to
impair the fundamentally strong position of such issues.

  "Aa"-Bonds which are rated Aa are judged to be of high quality by all
standards. Together with the Aaa group they comprise what are generally known
as high grade bonds. They are rated lower than the best bonds because margins
of protection may not be as large as in Aaa securities or fluctuation of
protective elements may be of greater amplitude or there may be other elements
present which make the long-term risks appear somewhat larger than in Aaa
securities.

  "A"-Bonds which are rated A possess many favorable investment attributes and
are to be considered as upper medium grade obligations. Factors giving
security to principal and interest are considered adequate, but elements may
be present which suggest a susceptibility to impairment some time in the
future.

  "Baa"-Bonds which are rated Baa are considered as medium grade obligations,
i.e., they are neither highly protected nor poorly secured. Interest payments
and principal security appear adequate for the present, but certain protective
elements may be lacking or may be characteristically unreliable over any great
length of time. Such bonds lack outstanding investment characteristics and in
fact have speculative characteristics as well.

  "Ba"-Bonds which are rated Ba are judged to have speculative elements; their
future cannot be considered as well assured. Often the protection of interest
and principal payments may be very moderate and thereby not well safeguarded
during both good and bad times over the future. Uncertainty of position
characterizes bonds in this class.

  "B"-Bonds which are rated B generally lack characteristics of a desirable
investment. Assurance of interest and principal payments or of maintenance of
other terms of the contract over any long period of time may be small.

  "Caa"-Bonds which are rated Caa are of poor standing. Such issues may be in
default or there may be present elements of danger with respect to principal
or interest.

  "Ca"-Bonds which are rated Ca represent obligations which are speculative in
a high degree. Such issues are often in default or have other marked
shortcomings.

  "C"-Bonds which are rated C are the lowest rated class of bonds and issues
so rated can be regarded as having extremely poor prospects of ever attaining
any real investment standing.

  Note: These bonds in the Aa, A, Baa, Ba and B groups which Moody's believes
possess the strongest investment attributes are designated by the symbols Aa1,
Al, Baa1, Ba1 and B1.

  Short-term Notes: The three ratings of Moody's for short-term notes are MIG
1/VMIG 1, MIG 2/VMIG 2, and MIG 3/VMIG 3; MIG 1 /VMIG 1 denotes "best quality,
enjoying strong protection from established cash flows"; MIG 2/VMIG 2 denotes
"high quality" with "ample margins of protection"; MIG 3/VMIG 3 instruments
are of "favorable quality . . . but . . . lacking the undeniable strength of
the preceding grades."

                                     IV-1


Description of Moody's Commercial Paper Ratings

  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
rated issuers:

    Issuers rated Prime-1 (or supporting institutions) have a superior
  ability for repayment of short-term promissory obligations. Prime-1
  repayment capacity will often be evidenced by the following
  characteristics: leading market positions in well established industries;
  high rates of return on funds employed; conservative capitalization
  structures with moderate reliance on debt and ample asset protection; broad
  margins, in earning coverage of fixed financial charges and high internal
  cash generation; and with established access to a range of financial
  markets and assured sources of alternate liquidity.

    Issuers rated Prime-2 (or supporting institutions) have a strong ability
  for repayment of short-term promissory obligations. This will normally be
  evidenced by many of the characteristics cited above but to a lesser
  degree. Earnings trends and coverage ratios, while sound, will be more
  subject to variation. Capitalization characteristics, while still
  appropriate, may be more affected by external conditions. Ample alternate
  liquidity is maintained.

    Issuers rated Prime-3 (or supporting institutions) have an acceptable
  ability for repayment of short-term promissory obligations. The effects of
  industry characteristics and market composition may be more pronounced.
  Variability in earnings and profitability may result in changes to the
  level of debt protection measurements and the requirement for relatively
  high financial leverage. Adequate alternate liquidity is maintained.

    Issuers rated Not Prime do not fall within any of the Prime rating
  categories.

Description of Standard & Poor's, a Division of The McGraw-Hill Companies,
Inc. ("Standard & Poor's"), Municipal Debt Ratings

  A Standard & Poor's municipal debt rating is a current assessment of the
creditworthiness of an obligor with respect to a specific financial
obligation, a specific class of financial obligations or a specific program.
It takes into consideration the creditworthiness of guarantors, insurers, or
other forms of credit enhancement on the obligation.

  The debt rating is not a recommendation to purchase, sell or hold a
financial obligation, inasmuch as it does not comment as to market price or
suitability for a particular investor.

  The ratings are based on current information furnished by the issuer or
obtained by Standard & Poor's from other sources Standard & Poor's considers
reliable. Standard & Poor's does not perform an audit in connection with any
rating and may, on occasion, rely on unaudited financial information. The
ratings may be changed, suspended or withdrawn as a result of changes in, or
unavailability of, such information, or based on other circumstances.

  The ratings are based, in varying degrees, on the following considerations:

    I. Likelihood of default-capacity and willingness of the obligor as to
  the timely payment of interest and repayment of principal in accordance
  with the terms of the obligation;

    II. Nature of and provisions of the obligation;

    III. Protection afforded to, and relative position of, the obligation in
  the event of bankruptcy, reorganization or other arrangement under the laws
  of bankruptcy and other laws affecting creditors' rights.

    AAA-Debt rated "AAA" has the highest rating assigned by Standard &
  Poor's. Capacity of the obligor to meet its financial commitment on the
  obligation is extremely strong.

                                     IV-2


    AA-Debt rated "AA" differs from the highest-rated issues only in small
  degree. The obligor's capacity to meet its financial commitment on the
  obligation is very strong.

    A-Debt rated "A" is somewhat more susceptible to the adverse effects of
  changes in circumstances and economic conditions than debt in higher-rated
  categories. However, the obligor's capacity to meet its financial
  commitment on the obligation is still strong.

    BBB-Debt rated "BBB" exhibits adequate protection parameters. However,
  adverse economic conditions or changing circumstances are more likely to
  lead to a weakened capacity of the obligor to meet its financial commitment
  on the obligation.

    BB, B, CCC, CC, C-Debt rated "BB," "B," "CCC," "CC", and "C" are regarded
  as having significant speculative characteristics. "BB" indicates the least
  degree of speculation and "C" the highest degree of speculation. While such
  debt will likely have some quality and protective characteristics, these
  may be outweighed by large uncertainties or major risk exposures to adverse
  conditions.

    D-Debt rated "D" is in payment default. The "D" rating category is used
  when payments on an obligation are not made on the date due even if the
  applicable grace period has not expired, unless Standard & Poor's believes
  that such payments will be made during such grace period. The "D" rating
  also will be used upon the filing of a bankruptcy petition or the taking of
  similar action if payments on an obligation are jeopardized.

  Plus (+) or Minus (-): The ratings from "AA" to "CCC" may be modified by the
addition of a plus or minus sign to show relative standing within the major
rating categories.

Description of Standard & Poor's Commercial Paper Ratings

  A 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 several categories, ranging from "A-1"
for the highest quality obligations to "D" for the lowest. These categories
are as follows:

    A-1-This designation indicates that the degree of safety regarding timely
  payment is strong. Those issues determined to possess extremely strong
  safety characteristics are denoted with a plus sign (+) designation.

    A-2-Capacity for timely payment on issues with this designation is
  satisfactory. However, the relative degree of safety is not as high as for
  issues designated "A-1."

    A-3-Issues carrying this designation have adequate capacity for timely
  payment. They are, however, more vulnerable to the adverse effects of
  changes in circumstances than obligations carrying the higher designations.

    B-Issues rated "B" are regarded as having only speculative capacity for
  timely payment.

    C-This rating is assigned to short-term debt obligations with a doubtful
  capacity for payment.

    D-Debt rated "D" is in payment default. The "D" rating category is used
  when interest payments or principal payments are not made on the date due,
  even if the applicable grace period has not expired unless Standard &
  Poor's believes that such payments will be made during such grace period.

    c-The "c" subscript is used to provide additional information to
  investors that the bank may terminate its obligation to purchase tendered
  bonds if the long-term credit rating of the issuer is below an investment-
  grade level and/or the issuer's bonds are deemed taxable.

    p-The letter "p" indicates that the rating is provisional. A provisional
  rating assumes the successful completion of the project financed by the
  debt being rated and indicates that payment of the debt service
  requirements is largely or entirely dependent upon the successful, 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. The
  investor should exercise his own judgment with respect to such likelihood
  and risk.

                                     IV-3


    Continuance of the ratings is contingent upon Standard & Poor's receipt
  of an executed copy of the escrow agreement or closing documentation
  confirming investments and cash flows.

    r-The "r" highlights derivative, hybrid, and certain other obligations
  that Standard & Poor's believes may experience high volatility or high
  variability in expected returns as a result of noncredit risks. Examples of
  such obligations are securities with principal or interest return indexed
  to equities, commodities, or currencies; certain swaps and options; and
  interest-only and principal-only mortgage securities. The absence of an "r"
  symbol should not be taken as an indication that an obligation will exhibit
  no volatility or variability in total return.

  A commercial paper rating is not a recommendation to purchase or sell a
security. The ratings are based on current information furnished to Standard &
Poor's by the issuer or obtained by Standard & Poor's from other sources it
considers reliable. The ratings may be changed, suspended, or withdrawn as a
result of changes in, or unavailability of, such information.

  A Standard & Poor's note rating reflects the liquidity factors and market
access risks unique to such notes. Notes due in three years or less will
likely receive a note rating. Notes maturing beyond three years will most
likely receive a long-term debt rating. The following criteria will be used in
making that assessment.

  --Amortization schedule--the larger the final maturity relative to other
   maturities, the more likely it will be treated as a note.

  --Source of payment--the more dependent the issue is on the market for its
   refinancing, the more likely it will be treated as a note.

  Note rating symbols are as follows:

    SP-1-Strong capacity to pay principal and interest. An issue determined
  to possess a very strong capacity to pay debt service is given a plus (+)
  designation.

    SP-2-Satisfactory capacity to pay principal and interest with some
  vulnerability to adverse financial and economic changes over the term of
  the notes.

    SP-3-Speculative capacity to pay principal and interest.

Description of Fitch IBCA, Inc.'s ("Fitch") Investment Grade Bond Ratings

  Fitch investment grade bond ratings provide a guide to investors in
determining the credit risk associated with a particular security. The rating
represents Fitch's assessment of the issuer's ability to meet the obligations
of a specific debt issue or class of debt in a timely manner.

  The rating takes into consideration special features of the issue, its
relationship to other obligations of the issuer, the current and prospective
financial condition and operating performance of the issuer and any guarantor,
as well as the economic and political environment that might affect the
issuer's future financial strength and credit quality.

  Fitch ratings do not reflect any credit enhancement that may be provided by
insurance policies or financial guarantees unless otherwise indicated.

  Bonds that have the same rating are of similar but not necessarily identical
credit quality since the rating categories do not fully reflect small
differences in the degrees of credit risk.

  Fitch ratings are not recommendations to buy, sell, or hold any security.
Ratings do not comment on the adequacy of market price, the suitability of any
security for a particular investor, or the tax-exempt nature or taxability of
payments made in respect of any security.

  Fitch ratings are based on information obtained from issuers, other
obligors, underwriters, their experts, and other sources Fitch believes to be
reliable. Fitch does not audit or verify the truth or accuracy of such

                                     IV-4


information. Ratings may be changed, suspended, or withdrawn as a result of
changes in, or the unavailability of, information or for other reasons.

  AAA-Bonds considered to be investment grade and of the highest credit
quality. The obligor has an exceptionally strong ability to pay interest and
repay principal, which is unlikely to be affected by reasonably foreseeable
events.

  AA-Bonds considered to be investment grade and of very high credit quality.
The obligor's ability to pay interest and repay principal is very strong,
although not quite as strong as bonds rated "AAA." Because bonds rated in the
"AAA" and "AA" categories are not significantly vulnerable to foreseeable
future developments, short-term debt of these issuers is generally rated "F-
1+."

  A-Bonds considered to be investment grade and of high credit quality. The
obligor's ability to pay interest and repay principal is considered to be
strong, but may be more vulnerable to adverse changes in economic conditions
and circumstances than bonds with higher ratings.

  BBB-Bonds considered to be investment grade and of satisfactory credit
quality. The obligor's ability to pay interest and repay principal is
considered to be adequate. Adverse changes in economic conditions and
circumstances, however, are more likely to have an adverse impact on these
bonds, and therefore impair timely payment. The likelihood that the ratings of
these bonds will fall below investment grade is higher than for bonds with
higher ratings.

  Plus (+) or Minus (-): Plus and minus signs are used with a rating symbol to
indicate the relative position of a credit within the rating category. Plus
and minus signs, however, are not used in the "AAA" category.

  NR Indicates that Fitch does not rate the specific issue.

  Conditional: A conditional rating is premised on the successful completion
of a project or the occurrence of a specific event.

  Suspended: A rating is suspended when Fitch deems the amount of information
available from the issuer to be inadequate for rating purposes.

  Withdrawn: A rating will be withdrawn when an issue matures or is called or
refinanced and, at Fitch's discretion, when an issuer fails to furnish proper
and timely information.

  FitchAlert: Ratings are placed on FitchAlert to notify investors of an
occurrence that is likely to result in a rating change and the likely
direction of such change. These are designated as "Positive," indicating a
potential upgrade, "Negative," for potential downgrade, or "Evolving," where
ratings may be raised or lowered. FitchAlert is relatively short-term, and
should be resolved within three to 12 months.

  Ratings Outlook: An outlook is used to describe the most likely direction of
any rating change over the intermediate term. It is described as "Positive" or
"Negative." The absence of a designation indicates a stable outlook.

Description of Fitch's Speculative Grade Bond Ratings

  Fitch speculative grade bond ratings provide a guide to investors in
determining the credit risk associated with a particular security. The ratings
("BB" to "C") represent Fitch's assessment of the likelihood of timely payment
of principal and interest in accordance with the terms of obligation for bond
issues not in default. For defaulted bonds, the rating ("DDD" to "D") is an
assessment of the ultimate recovery value through reorganization or
liquidation.

                                     IV-5


  The rating takes into consideration special features of the issue, its
relationship to other obligations of the issuer, the current and prospective
financial condition and operating performance of the issuer and any guarantor,
as well as the economic and political environment that might affect the
issuer's future financial strength.

  Bonds that have the rating are of similar but not necessarily identical
credit quality since rating categories cannot fully reflect the differences in
degrees of credit risk.

  BB-Bonds are considered speculative. The obligor's ability to pay interest
and repay principal may be affected over time by adverse economic changes.
However, business and financial alternatives can be identified which could
assist the obligor in satisfying its debt service requirements.

  B-Bonds are considered highly speculative. While bonds in this class are
currently meeting debt service requirements, the probability of continued
timely payment of principal and interest reflects the obligor's limited margin
of safety and the need for reasonable business and economic activity
throughout the life of the issue.

  CCC-Bonds have certain identifiable characteristics which, if not remedied,
may lead to default. The ability to meet obligations requires an advantageous
business and economic environment.

  CC-Bonds are minimally protected. Default in payment of interest and/or
principal seems probable over time.

  C-Bonds are in imminent default in payment of interest or principal.

  DDD, DD, D-Bonds are in default on interest and/or principal payments. Such
bonds are extremely speculative and should be valued on the basis of their
ultimate recovery value in liquidation or reorganization of the obligor. "DDD"
represents the highest potential for recovery on these bonds, and "D"
represents the lowest potential for recovery.

  Plus (+) or Minus (-): Plus and minus signs are used with a rating symbol to
indicate the relative position of a credit within the rating category. Plus
and minus signs, however, are not used in the "DDD," "DD," or "D" categories.

Description of Fitch's Short-Term Ratings

  Fitch's short-term ratings apply to debt obligations that are payable on
demand or have original maturities of up to three years, including commercial
paper, certificates of deposit, medium-term notes, and municipal and
investment notes.

  The short-term rating places greater emphasis than a long-term rating on the
existence of liquidity necessary to meet the issuer's obligations in a timely
manner.

  Fitch short-term ratings are as follows:


       
     F-1+ Exceptionally Strong Credit Quality. Issues assigned this rating are
          regarded as having the strongest degree of assurance for timely
          payment.

     F-1  Very Strong Credit Quality. Issues assigned this rating reflect an
          assurance of timely payment only slightly less in degree than issues
          rated "F-l+".

     F-2  Good Credit Quality. Issues assigned this rating have a satisfactory
          degree of assurance for timely payment, but the margin of safety is
          not as great as for issues assigned "F-1+" and "F-l" ratings.

     F-3  Fair Credit Quality. Issues assigned this rating have characteristics
          suggesting that the degree of assurance for timely payment is
          adequate; however, near-term adverse changes could cause these
          securities to be rated below investment grade.




                                     IV-6



      
     F-S Weak Credit Quality. Issues assigned this rating have characteristics
         suggesting a minimal degree of assurance for timely payment and are
         vulnerable to near-term adverse changes in financial and economic
         conditions.

     D   Default. Issues assigned this rating are in actual or imminent payment
         default.

     LOC The symbol "LOC" indicates that the rating is based on a letter of
         credit issued by a commercial bank.


                                      IV-7


                                                                      EXHIBIT V

policies (the "Policies") that the Fund may obtain from several insurance
companies with respect to insured Pennsylvania Municipal Bonds and Municipal
Bonds held by the Fund. The Fund has no obligation to obtain any such
Policies, and the terms of any Policies actually obtained may vary
significantly from the terms discussed below.

  In determining eligibility for insurance, insurance companies will apply
their own standards. These standards correspond generally to the standards
such companies normally use in establishing the insurability of new issues of
Pennsylvania Municipal Bonds and Municipal Bonds and are not necessarily the
criteria that would be used in regard to the purchase of such bonds by the
Fund. The Policies do not insure (i) municipal securities ineligible for
insurance and (ii) municipal securities no longer owned by the Fund.

  The Policies do not guarantee the market value of the insured Pennsylvania
Municipal Bonds and Municipal Bonds or the value of the shares of the Fund. In
addition, if the provider of an original issuance insurance policy is unable
to meet its obligations under such policy or if the rating assigned to the
insurance claims-paying ability of any such insurer deteriorates, the
insurance company will not have any obligation to insure any issue held by the
Fund that is adversely affected by either of the above described events. In
addition to the payment of premium, the policies may require that the Fund
notify the insurance company as to all Pennsylvania Municipal Bonds and
Municipal Bonds in the Fund's portfolio and permit the insurance company to
audit their records. The insurance premiums will be payable monthly by the
Fund in accordance with a premium schedule to be furnished by the insurance
company at the time the Policies are issued. Premiums are based upon the
amounts covered and the composition of the portfolio.

  The Fund will seek to utilize insurance companies that have insurance
claims-paying ability ratings of AAA from Standard & Poor's ("S&P") or Fitch
IBCA, Inc. ("Fitch") or Aaa from Moody's Investors Service, Inc. ("Moody's").
There can be no assurance, however, that insurance from insurance carriers
meeting these criteria will be at all times available.

  An S&P insurance claims-paying ability rating is an assessment of an
operating insurance company's financial capacity to meet obligations under an
insurance policy in accordance with the terms. An insurer with an insurance
claims-paying ability rating of AAA has the highest rating assigned by S&P.
Capacity to honor insurance contracts is considered by S&P to be extremely
strong and highly likely to remain so over a long period of time. A Fitch
insurance claims-paying ability rating provides an assessment of an insurance
company's financial strength and, therefore, its ability to pay policy and
contract claims under the terms indicated. An insurer with an insurance
claims-paying ability rating of AAA has the highest rating assigned by Fitch.
The ability to pay claims is adjudged by Fitch to be extremely strong for
insurance companies with this highest rating. In the opinion of Fitch,
foreseeable business and economic risk factors should not have any material
adverse impact on the ability of these insurers to pay claims. In Fitch's
opinion, profitability, overall balance sheet strength, capitalization and
liquidity are all at very secure levels and are unlikely to be affected by
potential adverse underwriting, investment or cyclical events. A Moody's
insurance claims-paying ability rating is an opinion of the ability of an
insurance company to repay punctually senior policyholder obligations and
claims. An insurer with an insurance claims-paying ability rating of Aaa is
considered by Moody's to be of the best quality. In the opinion of Moody's,
the policy obligations of an insurance company with an insurance claims-paying
ability rating of Aaa carry the smallest degree of credit risk and, while the
financial strength of these companies is likely to change, such changes as can
be visualized are most unlikely to impair the company's fundamentally strong
position.

  An insurance claims-paying ability rating of S&P, Fitch or Moody's does not
constitute an opinion on any specific contract in that such an opinion can
only be rendered upon the review of the specific insurance contract.
Furthermore, an insurance claims-paying ability rating does not take into
account deductibles, surrender or

                                      V-1


cancellation penalties or the timeliness of payment; nor does it address the
ability of a company to meet nonpolicy obligations (i.e., debt contracts).

  The assignment of ratings by S&P, Fitch or Moody's to debt issues that are
fully or partially supported by insurance policies, contracts or guarantees is
a separate process from the determination of claims-paying ability ratings.
The likelihood of a timely flow of funds from the insurer to the trustee for
the bondholders is a key element in the rating determination for such debt
issues.

                    SECTIONS 86 THROUGH 98 OF CHAPTER 156B
                       OF THE MASSACHUSETTS GENERAL LAWS
                 (THE MASSACHUSETTS BUSINESS CORPORATION LAW)

(S) 86. Sections applicable to appraisal; prerequisites

  If a corporation proposes to take a corporate action as to which any section
of this chapter provides that a stockholder who objects to such action shall
have the right to demand payment for his shares and an appraisal thereof,
sections eighty-seven to ninety-eight, inclusive, shall apply except as
otherwise specifically provided in any section of this chapter. Except as
provided in sections eighty-two and eighty-three, no stockholder shall have
such right unless (1) he files with the corporation before taking the vote of
the shareholders on such corporate action, written objection to the proposed
action stating that he intends to demand payment for his shares if the action
is taken and (2) his shares are not voted in favor of the proposed action.

(S) 87. Statement of rights of objecting stockholders in notice of meeting;
form

  The notice of the meeting of stockholders at which the approval of such
proposed action to be considered shall contain a statement of the rights of
objecting stockholders. The giving of such notice shall not be deemed to
create any rights in any stockholder receiving the same to demand payment for
his stock, and the directors may authorize the inclusion in any such notice of
a statement of opinion by the management as to the existence or non-existence
of the right of stockholders to demand payment for their stock on account of
the proposed corporate action. The notice may be in such form as the directors
or officers calling the meeting deem advisable, but the following form of
notice shall be sufficient to comply with this section:

    "If the action proposed is approved by the stockholders at the meeting
  and effected by the corporation, any stockholder (1) who files with the
  corporation before the taking of the vote on the approval of such action,
  written objection to the proposed action stating that he intends to demand
  payment for his shares if the action is taken and (2) whose shares are not
  voted in favor of such action has or may have the right to demand in
  writing from the corporation (or, in the case of a consolidation or merger,
  the name of the resulting or surviving corporation shall be inserted),
  within twenty days after the date of mailing to him of notice in writing
  that the corporate action has become effective, payment for his shares and
  an appraisal of the value thereof. Such corporation and any such
  stockholder shall in such cases have the rights and duties and shall follow
  the procedure set forth in sections 88 to 98, inclusive, of chapter 156B of
  the General Laws of Massachusetts."

(S) 88. Notice of effectiveness of action objected to

  The corporation taking such action, or in the case of a merger or
consolidation the surviving or resulting corporation, shall, within ten days
after the date on which such corporate action became effective, notify each
stockholder who filed a written objection meeting the requirements of section
eighty-six and whose shares were not voted in favor of the approval of such
action, that the action approved at the meeting of the corporation of which he
is a stockholder has become effective. The giving of such notice shall not be
deemed to create any rights in any stockholder receiving the same to demand
payment for his stock. The notice shall be sent by registered or certified
mail, addressed to the stockholder at his last known address as it appears in
the records of the corporation.

(S) 89. Demand for payment; time for payment

  If within twenty days after the date of mailing of a notice under subsection
(e) of section eighty-two, subsection (f) of section eighty-three, or section
eighty-eight, any stockholder to whom the corporation was required to give
such notice shall demand in writing from the corporation taking such action,
or in the case of a consolidation or merger from the resulting or surviving
corporation, payment for his stock, the corporation upon

                                     VI-1


which such demand is made shall pay to him the fair value of his stock within
thirty days after the expiration of the period during which such demand may be
made.

(S) 90. Demand for determination of value; bill in equity; venue

  If during the period of thirty days provided for in section eighty-nine the
corporation upon which such demand is made and any such objecting stockholder
fail to agree as to the value of such stock, such corporation or any such
stockholder may within four months after the expiration of such thirty-day
period demand a determination of the value of the stock of all such objecting
stockholders by a bill in equity filed in the superior court in the county
where the corporation in which such objecting stockholder held stock had or
has its principal office in the commonwealth.

(S) 91. Parties to suit to determine value; service

  If the bill is filed by the corporation, it shall name as parties respondent
all stockholders who have demanded payment for their shares and with whom the
corporation has not reached agreement as to the value thereof. If the bill is
filed by a stockholder, he shall bring the bill in his own behalf and in
behalf of all other stockholders who have demanded payment for their shares
and with whom the corporation has not reached agreement as to the value
thereof, and service of the bill shall be made upon the corporation by
subpoena with a copy of the bill annexed. The corporation shall file with its
answer a duly verified list of all such other stockholders, and such
stockholders shall thereupon be deemed to have been added as parties to the
bill. The corporation shall give notice in such form and returnable on such
date as the court shall order to each stockholder party to the bill by
registered or certified mail, addressed to the last known address of such
stockholder as shown in the records of the corporation, and the court may
order such additional notice by publication or otherwise as it deems
advisable. Each stockholder who makes demand as provided in section eighty-
nine shall be deemed to have consented to the provisions of this section
relating to notice, and the giving of notice by the corporation to any such
stockholder in compliance with the order of the court shall be sufficient
service of process on him. Failure to give notice to any stockholder making
demand shall not invalidate the proceedings as to other stockholders to whom
notice was properly given, and the court may at any time before the entry of a
final decree make supplementary orders of notice.

(S) 92. Decree determining value and ordering payment; valuation date

  After hearing the court shall enter a decree determining the fair value of
the stock of those stockholders who have become entitled to the valuation of
and payment for their shares, and shall order the corporation to make payment
of such value, together with interest, if any, as hereinafter provided to the
stockholders entitled thereto upon the transfer by them to the corporation of
the certificates representing such stock if certificated or, if
uncertificated, upon receipt of the instruction transferring such stock to the
corporation. For this purpose, the value of the shares shall be determined as
of the day preceding the date of the vote approving the proposed corporate
action and shall be exclusive of any element of value arising from the
expectation or accomplishment of the proposed corporate action.

(S) 93. Reference to special master

  The court in its discretion may refer the bill or any question arising
thereunder to a special master to hear the parties, make findings and report
the same to the court, all in accordance with the usual practice in suits in
equity in the superior court.

(S) 94. Notation on stock certificates of pendency of bill

  On motion the court may order stockholder parties to the bill to submit
their certificates of stock to the corporation for the notation thereon of the
pendency of the bill and may order the corporation to note such pendency in
its records with respect to any uncertificated shares held by such stockholder
parties, and may on motion dismiss the bill as to any stockholder who fails to
comply with such order.

                                     VI-2


(S) 95. Costs; interest

  The costs of the bill, including the reasonable compensation and expenses of
any master appointed by the court, but exclusive of fees of counsel or of
experts retained by any party, shall be determined by the court and taxed upon
the parties to the bill, or any of them, in such manner as appears to be
equitable, except that all costs of giving notice to stockholders as provided
in this chapter shall be paid by the corporation. Interest shall be paid upon
any award from the date of the vote approving the proposed corporate action,
and the court may on application of any interested party determine the amount
of interest to be paid in the case of any stockholder.

(S) 96. Dividends and voting rights after demand for payment

  Any stockholder who has demanded payment for his stock as provided in this
chapter shall not thereafter be entitled to notice of any meeting of
stockholders or to vote such stock for any purpose and shall not be entitled
to the payment of dividends or other distribution on the stock (except
dividends or other distributions payable to stockholders of record at a date
which is prior to the date of the vote, approving the proposed corporate
action) unless:

    1) A bill shall not be filed within the time provided in section ninety;

    2) A bill, if filed, shall be dismissed as to such stockholder; or

    3) Such stockholder shall with the written approval of the corporation,
  or in the case of a consolidation or merger, the resulting or surviving
  corporation, deliver to it a written withdrawal of his objections to and an
  acceptance of such corporate action.

  Notwithstanding the provisions of clauses (1) to (3), inclusive, said
stockholder shall have only the rights of a stockholder who did not so demand
payment for his stock as provided in this chapter.

(S) 97. Status of shares paid for

  The shares of the corporation paid for by the corporation pursuant to the
provisions of this chapter shall have the status of treasury stock, or in the
case of a consolidation or merger the shares or the securities of the
resulting or surviving corporation into which the shares of such objecting
stockholder would have been converted had he not objected to such
consolidation or merger shall have the status of treasury stock or securities.

(S) 98. Exclusive remedy; exception

  The enforcement by a stockholder of his right to receive payment for his
shares in the manner provided in this chapter shall be an exclusive remedy
except that this chapter shall not exclude in the right of such stockholder to
bring or maintain an appropriate proceeding to obtain relief on the ground
that such corporate action will be or is illegal or fraudulent as to him.

                                     VI-3

Item 15. Indemnification.

  Section 5.3 of the Registrant's Declaration of Trust, Article VI of the
Registrant's By-Laws and the Investment Advisory Agreement filed as Exhibit 6
provide for indemnification.

  Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be provided to directors, officers and controlling persons of the
Fund, pursuant to the foregoing provisions or otherwise, the Fund has been
advised that in the opinion of the Securities and Exchange Commission, such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Fund of expenses
incurred or paid by a director, officer or controlling person of the Fund in
connection with any successful defense of any action, suit or proceeding) is
asserted by such director, officer or controlling person in connection with
the securities being registered, the Fund will, unless in the opinion of its
counsel the matter has been settled by controlling precedent, submit to a
court of appropriate jurisdiction the question whether such indemnification by
it is against public policy as expressed in the Act and will be governed by
the final adjudication of such issue.

  Reference is made to Section seven of the Purchase Agreement, a form of
which is filed as Exhibit 7(a) hereto, for provisions relating to the
indemnification of the Underwriter.

of the Internal Revenue Service private letter ruling applied for or an
opinion of counsel as to certain tax matters, within a reasonable time after
receipt of such ruling or opinion.
