     The  Securities  and  Exchange  Commission has  not  approved  or
         disapproved these securities or  passed upon the adequacy
             of  this  Proxy  Statement  and  Prospectus.  Any

Pennsylvania, MuniVest Pennsylvania and MuniHoldings Pennsylvania that

and should be retained for future reference. Each of the Funds has authorized

  The address of the principal executive offices of MuniYield Pennsylvania,
MuniVest Pennsylvania and MuniHoldings Pennsylvania is 800 Scudders Mill Road,

<PAGE>


  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
<PAGE>

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
<PAGE>


  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
<PAGE>

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%.

  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

                                 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

                                 MuniYield Pennsylvania has outstanding Common
                                 Shares and one series of AMPS ("MuniYield
                                 Pennsylvania AMPS"). As of September 30,
                                 1999, MuniYield Pennsylvania had net assets

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
                                 Objectives and Policies."

                                 Pennsylvania AMPS.") As of September 30,
                                 1999, MuniVest Pennsylvania had net assets of
                                 $77,247,018.

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

                                 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
                                 $13.99 and the market price per share was
                                 $12.5625; (ii) the net asset value per share
                                 of MuniVest Pennsylvania Common Shares was
                                 $12.31 and the market price per share 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

                                 annual rate of 0.55% of such Fund's average
                                 weekly net assets, including assets acquired
                                 from the sale of AMPS. Subsequent to the
                                 Reorganization, FAM will continue to receive
                                 compensation pursuant to the investment
                                 advisory agreement with MuniYield
                                 Pennsylvania at the rate of 0.50% of the
                                 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

                                 for each Fund's AMPS. The Bank of New York

                                 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

                                 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

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
<PAGE>

  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
<PAGE>

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
<PAGE>


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
<PAGE>

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
<PAGE>

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
<PAGE>

  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
<PAGE>


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
<PAGE>

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
<PAGE>

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
<PAGE>

  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
<PAGE>

  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
<PAGE>

  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
<PAGE>

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
certain information with respect to the composition of MuniYield
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
<PAGE>

  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
<PAGE>

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.

*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.

 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
<PAGE>

  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
<PAGE>


  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
<PAGE>


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
<PAGE>

  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
<PAGE>

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
<PAGE>


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
<PAGE>

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
<PAGE>

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
<PAGE>


  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
<PAGE>

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
<PAGE>

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
<PAGE>


(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
<PAGE>


  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
<PAGE>

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:

<PAGE>

  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.

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
<PAGE>


  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.

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.

                   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:

</TABLE>
- --------

* 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
outstanding Common Shares of MuniHoldings Pennsylvania and owned no

  On the Record Date, Mr. Glenn, a Trustee and an officer of each 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
<PAGE>

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
<PAGE>

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.

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
as of October 31, 1998 were as follows:

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

As of October 31, 1998, net unrealized appreciation for Federal income tax
purposes aggregated $8,342,951, of which $8,362,443 related to appreciated
securities and $19,492 related to depreciated securities. The aggregate cost of
investments at October 31, 1998 for Federal income tax purposes was
$126,036,032.

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.

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 &

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.

purposes aggregated $6,359,671, of which $6,505,665 related to appreciated
securities and $145,994 related to depreciated securities. The aggregate cost of
investments at April 30, 1999 for Federal income tax purposes was $123,609,119.

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.

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) 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:

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

Shares issued and outstanding during the year ended October 31, 1998 increased
by 4,120 as a result of dividend reinvestment and during the year ended October
31, 1997 remained constant.

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 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.

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 November 5, 1998, the Fund's Board of Trustees declared an ordinary income
dividend to Common Shareholders in the amount of $.063266 per share, payable on
November 27, 1998 to shareholders of record as of November 20, 1998.

                              MuniVest Pennsylvania Insured Fund, April 30, 1999

- --------------------------------------------------------------------------------
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
<PAGE>

(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.

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.

(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.

2. Investment Advisory Agreement and Transactions with Affiliates:

The Fund has entered into an Investment Advisory Agreement with 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 0.55% of the Fund's average weekly net assets, including
proceeds from the issuance of Preferred Shares. For the period February 26, 1999
to March 31, 1999, FAM earned fees of $17,557, all of which was voluntarily
waived. In addition, FAM also reimbursed the Fund $13,971 in additional
expenses.

During the period February 26, 1999 to March 31, 1999, Merrill Lynch, Pierce,
Fenner & Smith Incorporated ("MLPF&S"), an affiliate of FAM, received
underwriting fees of $153,750 in connection with the issuance of the Fund's
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:

purposes aggregated $99,964, of which $16,911 related to appreciated securities
and $116,875 related to depreciated securities. The aggregate cost of
investments at March 31, 1999 for Federal income tax purposes was $53,374,890.

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.

                  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).

                  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
the period February 26, 1999 to April 30, 1999, all of which was waived. In
addition, FAM reimbursed the fund $15,089 in additional expenses.

  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.

                     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
<PAGE>

  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
to be legally bound, each of the Funds hereby agrees as follows:

1.Representations and Warranties of MuniYield Pennsylvania.

  MuniYield Pennsylvania represents and warrants to, and agrees with, the
Acquired Funds that:

    (a) MuniYield Pennsylvania is a trust with transferable shares, duly
  organized, validly existing and in good standing in conformity with the
  laws of the Commonwealth of Massachusetts, and has the power to own all of
  its assets and to carry out this Agreement. MuniYield Pennsylvania has all
  necessary Federal, state and local authorizations to carry on its business
  as it is now being conducted and to carry out this Agreement.

    (b) MuniYield Pennsylvania is duly registered under the 1940 Act as a
  non-diversified, closed-end management investment company (File No. 811-
  73136), and such registration has not been revoked or rescinded and is in
  full force and effect. MuniYield Pennsylvania has elected and qualified for
  the special tax treatment afforded regulated investment companies ("RICs")
  under Sections 851-855 of the Code at all times since its inception and
  intends to continue to so qualify until consummation of the Reorganization
  and thereafter.

                                     II-2
<PAGE>


    (c) Each of the Acquired Funds has been furnished with MuniYield
  Pennsylvania's Annual Report to Shareholders for the fiscal year ended
  October 31, 1998, and the audited financial statements appearing therein,
  having been audited by Deloitte & Touche LLP, independent public
  accountants, fairly present the financial position of MuniYield
  Pennsylvania as of the respective dates indicated, in conformity with
  generally accepted accounting principles applied on a consistent basis.

    (d) Each of the Acquired Funds has been furnished with MuniYield
  Pennsylvania's Semi-Annual Report to Shareholders for the six months ended
  April 30, 1999, and the unaudited financial statements appearing therein
  fairly present the financial position of MuniYield Pennsylvania as of the
  respective dates indicated, in conformity with generally accepted
  accounting principles applied on a consistent basis.

    (e) An unaudited statement of assets, liabilities and capital of
  MuniYield Pennsylvania and an unaudited schedule of investments of
  MuniYield Pennsylvania, each as of the Valuation Time (as defined in
  Section 5(d) of this Agreement), will be furnished to each of the Acquired
  Funds, at or prior to the Exchange Date for the purpose of determining the
  number of shares of MuniYield Pennsylvania Common Shares and MuniYield
  Pennsylvania Series B AMPS, to be issued pursuant to Section 6 of this
  Agreement; each will fairly present the financial position of MuniYield
  Pennsylvania as of the Valuation Time in conformity with generally accepted
  accounting principles applied on a consistent basis.

    (f) MuniYield Pennsylvania has full power and authority to enter into and
  perform its obligations under this Agreement. The execution, delivery and
  performance of this Agreement has been duly authorized by all necessary
  action of its Board of Trustees, and this Agreement constitutes a valid and
  binding contract enforceable in accordance with its terms, subject to the
  effects of bankruptcy, insolvency, moratorium, fraudulent conveyance and
  similar laws relating to or affecting creditors' rights generally and court
  decisions with respect thereto.

    (g) There are no material legal, administrative or other proceedings
  pending or, to the knowledge of MuniYield Pennsylvania, threatened against
  it which assert liability on the part of MuniYield Pennsylvania or which
  materially affect its financial condition or its ability to consummate the
  Reorganization. MuniYield Pennsylvania is not charged with or, to the best
  of its knowledge, threatened with any violation or investigation of any
  possible violation of any provisions of any Federal, state or local law or
  regulation or administrative ruling relating to any aspect of its business.

    (h) MuniYield Pennsylvania is not obligated under any provision of its
  Declaration of Trust or its by-laws or a party to any contract or other
  commitment or obligation, and is not subject to any order or 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.

    (i) There are no material contracts outstanding to which MuniYield
  Pennsylvania is a party that have not been disclosed in the N-14
  Registration Statement (as defined in subsection (l) below) or will not
  otherwise be disclosed to the Acquired Funds prior to the Valuation Time.

    (j) MuniYield 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 October 31,
  1999; and those incurred in connection with the Reorganization. As of the
  Valuation Time, MuniYield Pennsylvania will advise each Acquired Fund 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) No consent, approval, authorization or order of any court or
  governmental authority is required for the consummation by MuniYield
  Pennsylvania of the Reorganization, except such as may be required under
  the Securities Act of 1933, as amended (the "1933 Act"), the Securities
  Exchange Act of 1934, as amended (the "1934 Act") and the 1940 Act or state
  securities laws (which term as used herein shall include the laws of the
  District of Columbia and Puerto Rico).

    (l) The registration statement filed by MuniYield Pennsylvania on Form N-
  14 which includes the joint proxy statement of the Funds with respect to
  the transactions contemplated herein and the prospectus of MuniYield
  Pennsylvania relating to the MuniYield Pennsylvania Common Shares and

  Agreement, (the "Joint Proxy Statement and

                                     II-3
<PAGE>

  Prospectus"), and any supplement or amendment thereto or to the documents
  therein (as amended or supplemented, the "N-14 Registration Statement"), on
  its effective date, at the time of the shareholders' meetings referred to
  in Section 8(a) of this Agreement and at the Exchange Date, insofar as it
  relates to MuniYield Pennsylvania (i) complied or will comply in all
  material respects with the provisions of the 1933 Act, the 1934 Act and the
  1940 Act and the rules and regulations thereunder and (ii) did not or will
  not contain any untrue statement of a material fact or omit to state any
  material fact required to be stated therein or necessary to make the
  statements therein not misleading; and the Joint Proxy Statement and
  Prospectus included therein did not or will not contain any untrue
  statement of a material fact or omit to state any material fact necessary
  to make the statements therein, in the light of the circumstances under
  which they were made, not misleading; provided, however, that the
  representations and warranties in this subsection only shall apply to
  statements in or omissions from the N-14 Registration Statement made in
  reliance upon and in conformity with information furnished by MuniYield
  Pennsylvania for use in the N-14 Registration Statement as provided in
  Section 8(e) of this Agreement.

    (m) MuniYield Pennsylvania is authorized to issue an unlimited number of
  common shares of beneficial interest, par value $0.10 per share and
  1,000,000 preferred shares of beneficial interest, par value $0.05 per
  share. The Board of Trustees of MuniYield Pennsylvania has designated 1,600
  preferred shares as Auction Market Preferred Shares. Each outstanding
  common share of beneficial interest and each outstanding Auction Market
  Preferred Share of MuniYield Pennsylvania is fully paid and nonassessable
  and has full voting rights.

    (n) The MuniYield Pennsylvania Common Shares and MuniYield Pennsylvania
  Series B AMPS to be issued to the Acquired Funds pursuant to this Agreement
  will have been duly authorized and, when issued and delivered pursuant to
  this Agreement, will be legally and validly issued and will be fully paid
  and nonassessable and will have full voting rights, and no shareholder of
  MuniYield Pennsylvania will have any preemptive right of subscription or
  purchase in respect thereof.

    (o) At or prior to the Exchange Date, the MuniYield Pennsylvania Common
  Shares to be transferred to the Acquired Funds for distribution to the

  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
<PAGE>

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
<PAGE>

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
shall pay, subsequent to the Exchange Date and pro rata according to each
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
the preparation and distribution of the N-14 Registration Statement. Such fees
and expenses shall include the cost of preparing and filing a ruling request
with the Internal Revenue Service, legal and accounting fees, printing costs,
filing fees, shares exchange fees, rating agency fees, portfolio transfer
taxes (if any) and any similar expenses incurred in connection with the
Reorganization.

  (b) If for any reason the Reorganization is not consummated, no party shall
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
meeting of the shareholders of each fund and MuniHoldings Pennsylvania agrees
to call an annual meeting of its shareholders as soon as is practicable after
the effective date of the N-14 Registration Statement for the purpose of
considering the Reorganization as described in this Agreement.

  (b) Each Fund covenants to operate its business as presently conducted
between the date hereof and the Exchange Date.

  (c) Each Acquired Fund agrees that following the consummation of the
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
Act, the 1934 Act, the 1940 Act, and the rules and regulations thereunder and
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
returns, including any Forms 1099, required to be filed by such fund with
respect to its final taxable year ending with its complete liquidation and for
any prior periods or taxable years and further shall cause such tax returns
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
entitled to vote at each special or annual meeting of shareholders at which
action is to be considered regarding this Agreement, in sufficient time to
comply with requirements as to notice thereof, a combined proxy statement and
prospectus which complies in all material respects with the applicable
provisions of Section 14(a) of the 1934 Act and Section 20(a) of the 1940 Act,
and the rules and regulations, respectively, thereunder.

  (i) Following the consummation of the Reorganization, MuniYield Pennsylvania
will stay in existence and continue its business as a non-diversified, closed-
end management investment company registered under the 1940 Act.

<PAGE>

  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

  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

  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

  Applicable to the Funds and their Shareholders" and "Agreement and Plan of
  Reorganization--Tax Consequences of the Reorganization," (other than

  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

  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

  and officers. Such opinion also shall state that (a) while such counsel
  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

<PAGE>


  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
<PAGE>


  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
<PAGE>


    (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.

  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
  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

  percentages derived from such dollars) (with the exception of performance
  comparisons, if any), if any, has been obtained from the accounting records
  of the Acquired Fund or from schedules prepared by officials of the
  Acquired Fund having responsibility for financial and reporting matters and
  such information is in agreement with such records, schedules or
  computations made therefrom.

    (j) That the Acquired Fund Investments to be transferred to MuniYield
  Pennsylvania shall not include any assets or liabilities which MuniYield

  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 any Acquired Fund or
  would prohibit the Reorganization.

                                     II-19
<PAGE>


    (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
  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.

    (n) That all proceedings taken by each Acquired Fund and its respective
  counsel in connection with the Reorganization and all documents incidental

  Pennsylvania.

    (o) That prior to the Exchange Date, each of the Acquired Funds shall
  have declared a dividend or dividends which, together with all such
  previous dividends, shall have the effect of distributing to its
  shareholders all of its net investment company taxable income for the
  period 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, the last
  dividend period for the MuniVest Pennsylvania AMPS and the MuniHoldings
  Pennsylvania AMPS may be shorter than the dividend period for such AMPS
  determined as set forth in the applicable Certificate of Designation.

11.Termination, Postponement and Waivers.

  (a) Notwithstanding anything contained in this Agreement to the contrary,
this Agreement may be terminated and the Reorganization abandoned at any time
(whether before or after adoption thereof by the shareholders 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 Funds, (ii) by the Board of
Trustees of any Acquired Fund if any condition of such Acquired Fund's
obligations set forth in Section 9 of this Agreement has not been fulfilled or
waived by such Board; or (iii) by the Board of Trustees of MuniYield
Pennsylvania if any condition of MuniYield Pennsylvania's obligations set
forth in Section 10 of this Agreement have not been fulfilled or waived by
such Board.

  (b) If the transactions contemplated by this Agreement have not been
consummated by August 31, 2000, this Agreement automatically shall terminate
on that date, unless a later date is mutually agreed to by the Boards of
Trustees of the Funds.

  (c) In the event of termination of this Agreement pursuant to the provisions
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
of this Agreement may be waived by the Board of Trustees of any Fund
(whichever is entitled to the benefit thereof), if, in the judgment of such
Board after consultation with its counsel, such action or waiver will not have
a material adverse effect on the benefits intended under this Agreement to the
shareholders of their respective fund, on behalf of which such action is
taken. In addition, the Boards of Trustees of the Funds have delegated to FAM
the ability to make non-material changes to the transaction if it deems it to
be in the best interests of the Funds to do so.

  (e) The respective representations and warranties contained in Sections 1, 2
and 3 of this Agreement shall expire with, and be terminated by, the
consummation of the Reorganization, and no Fund nor any of its officers,
Trustees, trustees, agents or shareholders shall have any liability with
respect to such representations or warranties after the Exchange Date. This
provision shall not protect any officer, Trustee, trustee, agent or
shareholder of any Fund against any liability to the entity for which that
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.

<PAGE>

  (f) If any order or orders of the Commission with respect to this Agreement
shall be issued prior to the Exchange Date and shall impose any terms or
conditions which are determined by action of the Boards of Trustees of the
Funds to be acceptable, such terms and conditions shall be binding as if a
part of this Agreement without further vote or approval of the shareholders of
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
of any claim) which MuniYield Pennsylvania may incur or sustain by reason of
the fact that (i) MuniYield Pennsylvania shall be required to pay any
corporate obligation of such Acquired Fund, whether consisting of tax
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)
any covenant of such Acquired Fund has been breached in any material respect;
or (iv) 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 attributable to such Fund not misleading or (b) the Joint
Proxy Statement and Prospectus delivered to the 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 attributable to such Fund, in the light of the
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
<PAGE>

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.

  (a) Pursuant to Rule 145 under the 1933 Act, and in connection with the
issuance of any shares to any person who at the time of the Reorganization is,
to its knowledge, an affiliate of a party to the Reorganization pursuant to
Rule 145(c), MuniYield Pennsylvania will cause to be affixed upon the
certificate(s) issued to such person (if any) a legend as follows:

  THESE SHARES ARE SUBJECT TO RESTRICTIONS ON TRANSFER UNDER THE SECURITIES
  ACT OF 1933 AND MAY NOT BE SOLD OR OTHERWISE TRANSFERRED EXCEPT TO
  MUNIYIELD PENNSYLVANIA FUND (OR ITS STATUTORY SUCCESSOR), OR ITS PRINCIPAL
  UNDERWRITER UNLESS (I) A REGISTRATION STATEMENT WITH RESPECT THERETO IS
  EFFECTIVE UNDER THE SECURITIES ACT OF 1933 OR (II) IN THE OPINION OF
  COUNSEL REASONABLY SATISFACTORY TO THE FUND, SUCH REGISTRATION IS NOT
  REQUIRED.

and, further, that stop transfer instructions will be issued to MuniYield
Pennsylvania's transfer agent with respect to such shares. Each Acquired Fund
will provide MuniYield Pennsylvania on the Exchange Date with the name of any
shareholder of an Acquired Fund who is to the knowledge of such Acquired Fund
an affiliate of that Acquired Fund on such date.

  (b) All covenants, agreements, representations and warranties made under
this Agreement and any certificates delivered pursuant to this Agreement shall
be deemed to have been material and relied upon by each of the parties,
notwithstanding any investigation made by them or on their behalf.

  (c) Any notice, report or demand required or permitted by any provision of
this Agreement shall be in writing and shall be made by hand delivery, prepaid
certified mail or overnight service, addressed to any Fund, at 800 Scudders
Mill Road, Plainsboro, New Jersey 08536, Attn: Terry K. Glenn, President.

  (d) This Agreement supersedes all previous correspondence and oral
communications between the parties regarding the Reorganization, constitutes
the only understanding with respect to the Reorganization, may not be changed
except by a letter of agreement signed by each party and shall be governed by
and construed in accordance with the laws of the State of New York applicable

Trust. The execution and delivery of this Agreement have been authorized by
the Trustees of each Fund and signed by authorized officers of each Fund,
acting as such, and neither such authorization by such Trustees nor such
execution and delivery by such officers shall be deemed to have been made by
any of them individually or to impose liability on any of them personally, but
shall bind only the trust property of each Fund, as provided in such Fund's
Declaration of Trust.

                                                                    EXHIBIT III

                 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
<PAGE>


  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
<PAGE>


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.

  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.

  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.

 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
<PAGE>


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.

 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.

                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."

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
<PAGE>

    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
<PAGE>

    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
<PAGE>

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
<PAGE>

  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:

<TABLE>
     <C>  <S>
     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.

         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.

<PAGE>

                                                                      EXHIBIT V

                              PORTFOLIO INSURANCE

  Set forth below is further information with respect to the insurance
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
<PAGE>

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
<PAGE>

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
<PAGE>

(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.

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.

                                    Trustees
                                    --------

2.1. Number and Qualification.  The number of Trustees shall be fixed from
     ------------------------
time to time by written instrument signed by a majority of the Trustees then in
office, provided, however, that the number of Trustees shall in no event be less
than three or more than fifteen (except prior to the first public offering of
Shares of the Trust).  Any vacancy created by an increase in Trustees may, to
the extent permitted by the 1940 Act, be filled by the appointment of an
individual having the qualifications described in this Article made by a written
instrument signed by a majority of the Trustees then in office. Any such
appointment shall not become effective, however, until the individual named in
the written instrument of appointment shall have accepted in writing such
appointment and agreed in writing to be bound by the terms of this Declaration.
No reduction in the number of Trustees shall have the effect of removing any
Trustee from office prior to the expiration of this term. Whenever a vacancy in
the number of Trustees shall occur, until such vacancy is filled as provided in
Section 2.3 hereof, the Trustees in office, regardless of their number, shall
have all the powers granted to the Trustees and shall discharge all the duties
imposed upon the Trustees by this Declaration. A Trustee shall be an individual
at least 21 years of age who is not under legal disability. Trustees need not
own Shares.

2.2. Term of Office of Trustees. The term of office of all of the Trustees
     --------------------------
named herein, or elected or appointed prior to the first annual meeting of
Shareholders, shall expire on the date of the first annual meeting of
Shareholders or special meeting in lieu thereof. Beginning with the Trustees
elected at the first annual meeting of Shareholders, the term of each Trustee
shall expire at the next annual meeting of Shareholders following the election
or appointment of such Trustee and upon the election and qualification of his
Successor. The Trustees shall be elected by the affirmative vote of the holders
of a majority of the Shares present in person or by proxy at an annual meeting
of Shareholders or special meeting in lieu thereof called for that purpose,
except as provided in Section 2.3 of this Article; provided, however, that the
Preferred Shareholders voting as a class at an annual meeting of the
Shareholders or special meeting in lieu thereof called for such purpose, shall
elect at least two (2) Trustees at all times, and, provided, further, that the
Preferred Shareholders voting as a class shall elect at least a majority of the
Trustees, which number of Trustees shall be increased appropriately in order to
effectuate such rights after giving effect to resignations of Trustees, (i) if
at any time the dividends on the Preferred Shares shall be unpaid in an amount
equal to two (2) full years  dividends on the Preferred Shares, with such
representation to continue until all dividends in arrears shall have been paid
or otherwise provided for, or (ii) pursuant to the designations and powers,
preferences and rights and the qualifications, limitations and restrictions of
the Preferred Shares as determined in accordance with Section 6.1 hereof.  Each
Trustee elected shall hold office until his successor shall have been elected
and shall have qualified or until such time as may otherwise be provided in the
By-Laws adopted or amended pursuant to Section 2.7 hereof; except that (a) any
Trustee may resign his trust (without need for prior or subsequent accounting)
by an instrument in writing signed by him or her and delivered to the other
Trustees, which shall take effect upon such delivery or upon such later date as
is specified therein; (b) any Trustee may be removed (provided the aggregate
number of Trustees after such removal shall not be less than the number required
by Section 2.1 hereof) with cause, at any time by written instrument, signed

                                       4
<PAGE>

by the remaining Trustees, specifying the date when such removal shall become
effective, provided, however, that the Trustees elected by one class of Shares
shall have no power to so remove any Trustee elected by another class of Shares;
(c) any Trustee who requests in writing to he retired or who has become
incapacitated by illness or injury may be retired by written instrument signed
by a majority of the other Trustees, specifying the date of his retirement; and
(d) a Trustee may be removed at any meeting of Shareholders by a vote of two
thirds of the outstanding Shares of the class or classes of Shares of beneficial
interest that elected such Trustee. Upon the resignation or removal of a
Trustee, or his otherwise ceasing to be Trustee, he shall execute and deliver
such documents as the remaining Trustees shall require for the purpose of
conveying to the Trust or the remaining Trustees an Trust Property held in the
name of the resigning or removed Trustee. Upon the incapacity or death of any
Trustee, his legal representative shall execute and deliver on his behalf such
documents as the remaining Trustees shall require as provided in the preceding
sentence.

2.3. Resignation and Appointment of Trustees. In case of the declination,
     ---------------------------------------
death, resignation, retirement, removal or inability of any of the Trustees, or
in case a vacancy shall, by reason of an increase in number, or for any other
reason, exist, the remaining Trustees or, prior to the public offering of Shares
of the Trust, if only one Trustee shall then remain in office, the remaining
Trustee shall fill such vacancy by appointing such other person as they or he,
in their or his discretion, shall see fit. Such appointment shall be evidenced
by a written instrument signed by a majority of the remaining Trustees or by the
remaining Trustee, as the case may be. Any such appointment shall not become
effective, however, until the person named in the written instrument or
appointment shall have accepted in writing such appointment and agreed in
writing to be bound by the terms of the Declaration. Within twelve months of
such appointment, the Trustees shall cause notice of such appointment to be
mailed to each Shareholder at his address as recorded on the books of the Trust.
An appointment of a Trustee may be made by the Trustees then in office and
notice thereof mailed to Shareholders aforesaid in anticipation of a vacancy to
occur by reason of retirement, resignation or increase in number of Trustees
effective at a later date, provided that said appointment shall become effective
only at or after the effective date of said retirement, resignation or increase
in number of Trustees. The power of appointment is subject to the provisions of
Section 16(a) of the 1940 Act.

2.4. Vacancies. The death, declination, resignation, retirement, removal or
     ---------
incapacity of the Trustees, or any one of them, shall not operate to annul the
Trust or to revoke any existing agency created pursuant to the terms of this
Declaration. Whenever a vacancy in the number of Trustees shall occur, until
such vacancy is filled as provided in Section 2.3, the Trustees in office,
regardless of their number, shall have all the powers granted to the Trustees
and shall discharge all the duties imposed upon the Trustees by the Declaration
subject to the right of the holders of the Preferred Shares to elect a Trustee
to fill such vacancy in accordance with the terms and provisions hereof. A
written instrument certifying the existence of such vacancy signed by a majority
of the Trustees shall be conclusive evidence of the existence of such vacancy.

2.5. Meetings. Meetings of the Trustees shall be held from time to time upon
     --------
the call of the Chairman, if any, the President, the Secretary or any two
Trustees. Regular meetings of the Trustees may be held without call or notice at
a time and place fixed by the By-Laws or by resolution of the Trustees. Notice
of any other meeting shall be mailed or otherwise given not

                                       5
<PAGE>

less than 48 hours before the meeting but may be waived in writing by any
Trustee either before or after such meeting. The attendance of a Trustee at a
meeting shall constitute a waiver of notice of such meeting except where a
Trustee attends a meeting for the express purpose of objecting to the
transaction of any business on the ground that the meeting has not been lawfully
called or convened. The Trustees may act with or without a meeting. A quorum for
all meetings of the Trustees shall be a majority of the Trustees. Unless
provided otherwise in this Declaration, any action of the Trustees may be taken
at a meeting by vote of a majority of the Trustees present (a quorum being
present) or without a meeting by written consents of a majority of the Trustees.

     Any committee of the Trustees, including an executive committee, if any,
may act with or without a meeting. A quorum for all meetings of any such
committee shall be a majority of the members thereof. Unless provided otherwise
in this Declaration, any action of any such committee may be taken at a meeting
by vote of a majority of the members present (a quorum being present) or without
a meeting by written consent of a majority of the members.

     With respect to actions of the Trustees and any committee of the Trustees,
Trustees who are Interested Persons of the Trust within the meaning of Section
1.2 hereof or otherwise interested in any action to be taken may be counted for
quorum purposes under this Section and shall be entitled to vote to the extent
permitted by the 1940 Act.

     All or any one or more Trustees may participate in a meeting of the
Trustees or any committee thereof by means of a conference telephone or similar
communications equipment by means of which all persons participating in the
meeting can hear each other and participation in a meeting pursuant to such
communications systems shall constitute presence in person at such meeting.

2.6. Officers. The Trustees shall annually elect a President, a Secretary and
     --------
a Treasurer and may elect a Chairman. The Trustees may elect or appoint or
authorize the Chairman, if any, or President to appoint such other officers or
agents with such powers as the Trustees may deem to be advisable. The Chairman
and President shall be and the Secretary and Treasurer may, but need not, be a
Trustee.

2.7. By-Laws. The Trustees may adopt and from time to time amend or repeal
     -------
the By-Laws for the conduct of the business of the Trust.

3.1. General.  The Trustees shall have exclusive and absolute control over
     -------
the Trust Property and over the business of the Trust to the same extent as if
the Trustees were the sole owners of the Trust Property and business in their
own right, but with such powers of delegation as may be permitted by this
Declaration. The Trustees may perform such acts as in their sole discretion are
proper for conducting the business of the Trust. The enumeration of any specific
power herein shall not be construed as limiting the aforesaid power. Such powers
of the Trustees may be exercised without order of or resort to any court.

     The right, title and interest of the Trustees in the Trust Property shall
vest automatically in each person who may hereafter become a Trustee upon his
due election and qualification. Upon the resignation, removal or death of a
Trustee he shall automatically, cease to have any right, title or interest in

or undertake the performance of any obligation, contract or engagement of any
other person, firm, association or corporation.

3.6. Delegation; Committees. The Trustees shall have power, consistent with
     ----------------------
their continuing exclusive authority over the management of the Trust and the
Trust Property, to delegate from time to time to such of their number or to
officers, employees or agents of the Trust the doing of such things and the
execution of such instruments either in the name of the Trust or the names of
the Trustees or otherwise as the Trustees may deem expedient, to the same extent
as such delegation is permitted to directors of a Massachusetts business
corporation and is permitted by the 1940 Act.

     ----------------------
property due to the Trust; to pay all claims including taxes, against the Trust

compensation of all officers, employees and Trustees. The Trustee may pay
themselves such compensation for special services, including legal,
underwriting, syndicating and brokerage services, as they in good faith may deem
reasonable and reimbursement for expenses reasonably incurred by themselves on
behalf of the Trust.

3.9. Miscellaneous Powers. The Trustees shall have the power to: (a) employ
     --------------------
or contract with such Persons as the Trustees may deem desirable for the
transaction of the business of the Trust; (b) enter into joint ventures,

<PAGE>

associations; (c) purchase, and pay for out of Trust Property, insurance
policies insuring the Shareholders, Trustees, officers, employees, agents,
investment advisers, distributors, selected dealers or independent contractors
of the Trust against all claims arising by reason of holding any such position
or by reason of any action taken or omitted by any such Person in such capacity,
whether or not constituting negligence, or whether or not the Trust would have
the power to indemnify such Person against such liability; (d) establish
pension, profit-sharing, share purchase, and other retirement, incentive and
benefit plans for any Trustees officers, employees and agents of the Trust; (e)
make donations, irrespective of benefit to the Trust, for charitable, religious,

of the Trust and carry on its operations in any and all of its branches and
maintain offices both within and without the Commonwealth of Massachusetts, in

possessions, agencies or instrumentalities of the United States of America and
of foreign governments, and to do all such other things and execute all such
instruments as they deem necessary, proper or desirable in order to promote the
interests of the Trust although such things are not herein specifically
mentioned. Any determination as to what is in the interests of the Trust made by
the Trustees in good faith shall be conclusive. In construing the provisions of
this Declaration, the presumption shall be in favor of a grant of power to the
Trustees. The Trustees will not be required to obtain any court order to deal
with the Trust Property.

                    Management and Distribution Arrangements
                    ----------------------------------------

4.1. Management Arrangements. Subject to a Majority Shareholder Vote, as
     -----------------------
required by the 1940 Act, the Trustees may in their discretion from time to time
enter into advisory or management contracts whereby the other party to such
contract shall undertake to furnish the Trustees such advisory and management
services as the Trustees shall from time to time consider desirable and all upon
such terms and conditions as the Trustees may in their discretion determine.
Notwithstanding any provisions of this Declaration, the Trustees may authorize
any adviser or manager (subject to such general or specific instructions as the
Trustees may from time to time adopt) to effect purchases, sales, loans or
exchanges of portfolio securities of the Trust on behalf of the Trustees or may
authorize any officer, employee or Trustee to effect such purchases, sales,
loans or exchanges pursuant to recommendations of any such adviser or manager
(and all without further action by the Trustees).  Any such purchases, sales,
loans and exchanges shall be deemed to have been authorized by all of the
Trustees.

4.2. Distribution Arrangements. The Trustees may in their discretion from
     -------------------------
time to time enter into a contract, providing for the sale of the Shares of the
Trust to net the Trust not less than the par value per share, whereby the Trust
may either agree to sell the Shares to the other party to the contract or
appoint such other party its sales agent for such Shares. In either case, the
contract shall be on such terms and conditions as the Trustees may in their
discretion determine not inconsistent with the provisions of this Article IV or
the By-Laws; and such contract may also provide for the repurchase or sale of
Shares by such other party as principal or as agent of the Trust and may provide
that such other party may enter into selected dealer agreements with registered
securities dealers to further the purpose of the distribution or repurchase of
the Shares.

4.3. Parties to Contract. Any contract of the character described in Section
     -------------------
4.1 and 4.2 of this Article IV or in Article VII hereof may be entered into with
any corporation, firm, trust or association, although one or more of the
Trustees or officers of the Trust may be an officer, director, Trustee,
shareholder, or member of such other party to the contract, and no such contract
shall be invalidated or rendered voidable by reason of the existence of any such
relationship, nor shall any person holding such relationship be liable merely by
reason of such relationship for any loss or expense to the Trust under or by
reason of said contract or accountable for any profit realized directly or
indirectly therefrom, provided that the contract when entered into was
reasonable and fair and not inconsistent with the provisions of this Article IV
or the By-Laws. The same person (including a, firm, corporation, trust, or
association) may be the other party to contracts entered into pursuant to
Sections 4.1 and 4.2 above or Article VII, and any individual may be financially
interested or otherwise affiliated with persons who are parties to any or all of
the contracts mentioned in this Section 4.3.

4.4. Provisions and Amendments. Any contract entered into pursuant to Section
     -------------------------
4.1 and 4.2 of this Article IV shall be consistent with and subject to the
requirements of Section 15 of the 1940 Act with respect to its continuance in
effect, its termination, and the method of authorization and approval of such
contract or renewal thereof, and no amendment to any contract, entered into
pursuant to Section 4.1 shall be effective unless assented to by a Majority
Shareholder Vote.

                   Limitations of Liability of Shareholders,
                              Trustees and Others
                              -------------------

5.1. No Personal Liability of Shareholders, Trustees, etc.  No shareholder
     -----------------------------------------------------
shall be subject to any personal liability whatsoever to any Person in
connection with Trust Property or the acts, obligations or affairs of the Trust.
No Trustee, officer, employee or agent of the Trust shall be subject to any
personal liability whatsoever to any Person, other than the Trust or its
Shareholders, in connection with Trust Property or the affairs of the Trust,
save only that arising from his bad faith, willful misfeasance, gross negligence
or reckless disregard of his duty to such Person; and all such Persons shall
look solely to the Trust Property for satisfaction of claims of any nature
arising in connection with the affairs of the Trust. If any Shareholder,
Trustee, officer, employee, or agent, as such, of the Trust, is made a party to
any suit or proceeding to enforce any such liability, he shall not on account
thereof, be held to any personal liability.  The Trust shall indemnify and hold
each Shareholder harmless from and against all claims and liabilities, to which
such Shareholder may become subject by reason of his being or having been a
Shareholder, and shall reimburse such Shareholder for all legal and other
expenses reasonably incurred by him in connection with any such claim or
liability.  The rights accruing to a Shareholder under this Section 5.1 shall
not exclude any other right to which such Shareholder may be lawfully entitled,
nor shall anything herein contained restrict the right of the Trust to indemnify
or reimburse a Shareholder in any appropriate situation even though not
specifically provided herein.

5.2. Non-Liability of Trustees, etc.  No Trustee, officer, employee or agent
     -------------------------------
of the Trust shall be liable to the Trust, its Shareholders, or to any
Shareholder, Trustee, officer, employee, or agent thereof for any action or
failure to act (including without limitation the failure to compel in any way
any former or acting Trustee to redress any breach of trust) except for his own
bad faith, willful misfeasance, gross negligence or reckless disregard of his
duties.

5.3. Mandatory Indemnification.  The Trust shall indemnify each of its
     -------------------------
Trustees, officers, employees, and agents (including persons who serve at its
requests as directors, officers or trustees of another organization in which it
has any interest, as a shareholder, creditor or otherwise) against all
liabilities and expenses (including amounts paid in satisfaction of judgments,
in compromise, as fines and penalties, and as counsel fees) reasonably incurred
by him in connection with the defense or disposition of any action, suit or
other proceeding, whether civil or criminal, in which he may be involved or with
which he may be threatened, while in office or thereafter, by reason of his
being or having been such a Trustee, officer, employee or agent, except with
respect to any matter as to which he shall have been adjudicated to have acted
in bad faith, willful misfeasance, gross negligence or reckless disregard of his
duties; provided, however, that as to any matter disposed of by a compromise
payment by such person, pursuant to a consent decree or otherwise, no
indemnification either for said payment or for any other expenses shall be
provided unless the Trust shall have received a written opinion from independent
legal counsel approved by the Trustees to the effect that if either the matter
of willful misfeasance, gross negligence or reckless disregard of duty, or the
matter of good faith and reasonable belief as to the best interests of the
Trust, had been adjudicated, it would have been adjudicated in favor of such
person. The rights accruing to any Person under these

                                       11
<PAGE>

provisions shall not exclude any other right to which he may be lawfully
entitled; provided that no Person may satisfy any right of indemnity or
reimbursement granted herein or in Section 5.1 or to which he may be otherwise
entitled except out of the property of the Trust, and no Shareholder shall be
personally liable to any Person with respect to any claim for indemnity or
reimbursement or otherwise. The Trustees may make advance payments in connection
with indemnification under this Section 5.3, provided that the indemnified
person shall have given a written undertaking to reimburse the Trust in the
event it is subsequently determined that he is not entitled to such
indemnification.

5.4. No Bond Required of Trustees.  No Trustee shall, as such, be obligated
     ----------------------------
to give any bond or surety or other security for the performance of any of his
duties hereunder.

5.5. No Duty of Investigation; Notice in Trust Instruments, etc.  No
     -----------------------------------------------------------
purchaser, lender, transfer agent or other person dealing with the Trustees or
any officer, employee or agent of the Trust shall be bound to make any inquiry
concerning the validity of any transaction purporting to be made by the Trustees
or by said officer, employee or agent or be liable for the application of money
or property paid, loaned, or delivered to or on the order of the Trustees or of
said officer, employee or agent. Every obligation, contract, instrument,
certificate, Share, other security of the Trust or undertaking, and every other
act or thing whatsoever executed in connection with the Trust shall be
conclusively taken to have been executed or done by the executors thereof only
in their capacity as Trustees under this Declaration or in their capacity as
officers, employees or agents of the Trust. Every written obligation, contract,
instrument, certificate, Share, other security of the Trust or undertaking made
or issued by the Trustees or by any officers, employees or agents of the Trust,
in their capacity as such, shall contain an appropriate recital to the effect
that the Shareholders, Trustees, officers, employees and agents of the Trust
shall not personally be bound by or liable thereunder, nor shall resort be had
to their private property for the satisfaction of any obligation or claim
thereunder, and appropriate references shall be made therein to the Declaration,
and may contain any further recital which they may deem appropriate, but the
omission of such recital shall not operate to impose personal liability on any
of the Trustees, Shareholders, officers, employees or agents of the Trust. The
Trustees may maintain insurance for the protection of the Trust Property, its
Shareholders, Trustees, officers, employees and agents in such amount as the
Trustees shall deem adequate to cover possible tort liability, and such other
insurance as the Trustees in their sole judgment shall deem advisable.

5.6. Reliance on Experts, etc. Each Trustee and officer or employee of the
     -------------------------
Trust shall, in the performance of his duties, be fully and completely justified
and protected with regard to any act or any failure to act resulting from
reliance in good faith upon the books of account or other records of the Trust,
upon an opinion of counsel, or upon reports made to the Trust by any of its
officers or employees or by any investment adviser, distributor, selected
dealers, accountants, appraisers or other experts or consultants elected with
reasonable care by the Trustees, officers or employees of the, Trust, regardless
of whether such counsel or expert may also be a Trustee.

                                  ARTICLE VI

                         Shares of Beneficial Interest
                         -----------------------------

6.1. Beneficial Interest.  The interest of the beneficiaries hereunder shall
     -------------------
be divided into transferable shares of beneficial interest of $0.10 par value.
The Trustees of the Trust 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. The number of such shares of beneficial interest authorized hereunder
is unlimited.  All Shares issued hereunder including, without limitation, Shares
issued in connection with a dividend in Shares or a split in Shares, shall be
fully, paid and nonassessable.

     Pursuant to the powers vested in the Trustees by this Section 6.1, the
Trustees hereby authorize the issuance of an unlimited number of common shares
of beneficial interest, par value $0.10 per share (the "Common Shares"),
together with 1,000,000 preferred shares of beneficial interest, par value of
$0.10 per share (the "Preferred Shares").

     The designations and powers, preferences and rights, and the
qualifications, limitations and restrictions of the Common Shares are as set
forth in this Declaration of Trust.

     The designations and powers, preferences and rights, and the
qualifications, limitations and restrictions of the Preferred Shares are as
follows:

     The Preferred Shares shall be issued from time to time in one or more
series with such distinctive serial designations and (i) may have such voting
powers, full or limited; (ii) may be subject to redemption at such time or times
and at such price or prices; (iii) may be entitled to receive dividends (which
may be cumulative or noncumulative) at such rate or rates, on such conditions,
and at such times, and payable in preference to, or in such relation to, the
dividends payable on any other class or classes of shares; (iv) may have such
preferences or other rights upon the dissolution of, or upon any distribution of
the assets of, the Trust; (v) may be made convertible into, or exchangeable for,
shares of any other class or classes of shares of the Trust, at such price or
prices or at such rates of exchange and with such adjustments; (vi) shall have
such other relative, participating, optional or other special rights,
qualifications, limitations or restrictions thereof, all as shall hereafter be
stated and expressed in, the resolution or resolutions providing for the issue
of such Preferred Shares from time to time adopted by the Trustees pursuant to
authority so to do which is hereby expressly vested in the Board; and are as
further set out in this Declaration of Trust. A certificate signed by the
Secretary or an Assistant Secretary of the Trust setting forth the resolution or
resolutions providing for such issuance of Preferred Shares and reciting that
such resolution was or such resolutions were duly adopted by the Trustees (the
"Certificate of Designation") shall be conclusive evidence of the action
providing for the issuance of such Preferred Shares when lodged among the
records of the Trust.

6.2. Rights of Shareholders.  The ownership of the Trust Property of every
     ----------------------
description and the right to conduct any business hereinbefore described are
vested exclusively in the Trustees, and the Shareholders shall have no interest
therein other than the beneficial interest conferred by their Shares, and they
shall have no right to call for any partition or division of any property,
profits, rights or interests of the Trust nor can they be called upon to share
or assume

                                       13
<PAGE>

any losses of the Trust or suffer an assessment of any kind by virtue of their
ownership of Shares. The Shares shall be personal property giving only the
rights in this Declaration specifically set forth. The Shares shall not entitle
the holder to preference, preemptive, appraisal, conversion or exchange rights,
except for rights or appraisal specified in Section 10.4 and except as the
Trustees may determine with respect to any class or series of Shares.

6.3. Trust Only.  It is the intention of the Trustees to create only the
     ----------
relationship of Trustee and beneficiary between the Trustees and each
Shareholder from time to time. It is not the intention of the Trustees to create
a general partnership, limited partnership, joint stock association,
corporation, bailment or any form of legal relationship other than a trust.
Nothing in this Declaration shall be construed to make the Shareholders, either
by themselves or with the Trustees, partners or members of a joint stock
association.

6.4. Issuance of Shares.  The Trustees, in their discretion, may from time to
     ------------------
time without a vote of the Shareholders issue Shares, in addition to the then
issued and outstanding Shares and Shares held in the treasury, to such party or
parties and for such amount not less than par value and type of consideration,
including cash or property, at such time or times, and on such terms as the
Trustees may deem best, and may in such manner acquire other assets (including
the acquisition of assets subject to, and in connection with the assumption of,
liabilities) and businesses. In connection with any issuance of Shares, the
Trustees may issue fractional Shares. The Trustees may from time to time divide
or combine the Shares into a greater or lesser number without thereby changing
the proportionate beneficial interests in the Trust. Contributions to the Trust
may be accepted for, and Shares shall be redeemed as whole Shares and/or
1/1,000ths of a Share or multiples thereof.

6.5. Register of Shares. A register shall be kept at the Trust or a transfer
     ------------------
agent duly appointed by the Trustees under the direction of the Trustees which
shall contain the names and addresses of the Shareholders and the number of
Shares held by them respectively and a record of all transfers thereof.  Such
register shall be conclusive as to who are the holders of the Shares and who
shall be entitled to receive dividends or distributions or otherwise to exercise
or enjoy the rights of Shareholders. No Shareholder shall be entitled to receive
payment of any dividend or distribution, nor to have notice given to him as
herein provided, until he has given his address to a transfer agent or such
other officer or agent of the Trustees as shall keep the said register for entry
thereon. It is not contemplated that certificates will be issued for the Shares;
however, the Trustees, in their discretion, may authorize the issuance of share
certificates and promulgate appropriate rules and regulations as to their use.

6.6. Transfer Agent and Registrar.  The Trustee shall have power to employ a
     ----------------------------
transfer agent or transfer agents, and a registrar or registrars. The transfer
agent or transfer agents may keep the said register and record therein the
original issues and transfers, if any, of the said shares. Any such transfer
agent and registrar shall perform the duties usually performed by transfer
agents and registrars of certificates of stock in a corporation, except as
modified by the Trustees.

6.7. Transfer of Shares.  Shares shall be transferable on the records of the
     ------------------
Trust only by the record holder thereof or by his agent thereto duly authorized
in writing, upon delivery to the Trustees or a transfer agent of the Trust of a
duly executed instrument of transfer, together

                                       14
<PAGE>

with such evidence of the genuineness of each such execution and authorization
and of other matters as may reasonably be required. Upon such delivery the
transfer shall be recorded on the register of the Trust. Until such record is
made, the Shareholder of record shall be deemed to be the holder of such Shares
for all purposes hereof and neither the Trustees nor any transfer agent or
registrar nor any officer, employee or agent of the Trust shall be affected by
any notice of the proposed transfer.

     Any person becoming entitled to any Shares in consequence of the death,
bankruptcy, or incompetence of any Shareholder, or otherwise by operation of
law, shall be recorded on the register of Shares as the holder of such Shares
upon production of the proper evidence thereof to the Trustees or a transfer
agent of the Trust, but until such record is made, the Shareholder of record
shall be deemed to be the holder of such Shares for all purposes hereof and
neither the Trustees nor any transfer agent or registrar nor any officer or
agent of the Trust shall be affected by any notice of such death, bankruptcy or
incompetence, or other operation of law.

6.8. Notices.  Any and all notices to which any Shareholder hereunder may be
     -------
entitled and any and all communications shall be deemed duly served or given if
mailed, postage prepaid, addressed to any Shareholder of record, at his last
known address as recorded on the register of the Trust.

                                   ---------

7.1. Appointment and Duties.  The Trustees shall at all times employ
     ----------------------
custodian or custodians, meeting the qualifications for custodians for portfolio
securities of investment companies contained in the 1940 Act, as custodian with
authority as its agent, but subject to such restrictions, limitations and other
requirements, if any, as may be contained in the By-Laws of the Trust and the
1940 Act:

(1)  to hold the securities owned by the Trust and deliver the same upon
     written order;

(2)  to receive and receipt for any moneys due to the Trust and deposit the
     same in its own banking department or elsewhere as the Trustees may direct;

(3)  to disburse such funds upon orders or vouchers;

(4)  if authorized by the Trustees, to keep the books and accounts of the Trust
     and furnish clerical and accounting services; and

(5)  if authorized to do so by the Trustees, to compute the net income of the
     Trust;

all upon such basis of compensation as may be agreed upon between the Trustees
and the custodian. If so directed by a majority Shareholder Vote, the custodian
shall deliver and pay over all property of the Trust held by it as specified in
such vote.

     The Trustees may also authorize the custodian to employ one or more sub-
custodians from time to time to perform such of the acts and services of the
custodian and upon such terms and conditions, as may be agreed upon between the
custodian and such sub-custodian and approved by the Trustees, provided that in
every case such sub-custodian shall meet the qualifications for custodians
contained in the 1940 Act.

7.2. Central Certificate System. Subject to such rules, regulations and
     --------------------------
orders as the Commission may adopt, the Trustees may direct the custodian to
deposit all or any part of the securities owned by the Trust in a system for the
central handling of securities established by a national securities exchange or
a national securities association registered with the Commission under the
Securities Exchange Act of 1934, or such other person as may be permitted by the
Commission, or otherwise in accordance with the 1940 Act, pursuant to which
system all securities of any particular class or series of any issuer deposited
within the system are treated as fungible and may be transferred or pledged by
bookkeeping entry without physical delivery of such securities, provided that
all such deposits shall be subject to withdrawal only upon the order of the
Trust.

8.1. Net Asset Value.  The net asset value of each outstanding Share of the
     ---------------
Trust shall be determined at such time or times on such days as the Trustees may
determine, in accordance with the 1940 Act. The method of determination of net
asset value of Shares of each class shall be determined by the Trustees and
shall be as set forth in the Prospectus and Registration Statement with any
expenses being borne solely by a class of Shares being reflected in the net
asset value of such Shares. The power and duty to make the daily calculations
may be delegated by the Trustees to the adviser, administrator, manager,
custodian, transfer agent or such other person as the Trustees may determine.
The Trustees may suspend the daily determination of net asset value to the
extent permitted by the 1940 Act.

8.2. Distributions to Shareholders. The Trustees shall from time to time
     -----------------------------
distribute ratably among the Shareholders such proportion of the net profits,
surplus (including paid-in surplus), capital, or assets held by the Trustees as
they deem proper with any expenses being borne solely by a class of Shares being
reflected in the net profits or other assets being distributed to such class.
Such distribution may be made in cash or property (including without limitation
any type of obligations of the Trust or any assets thereof), and the Trustees
may distribute ratably among the Shareholders additional Shares issuable
hereunder in such manner, at such times, and on such terms as the Trustee; may
deem proper. Such distributions may be among the Shareholders of record at the
time of declaring a distribution or among the Shareholders of record at such
later date as the Trustees shall determine. The Trustees may always retain from
the net profits such amounts as they may deem necessary to pay the debts or
expenses of the Trust or to meet obligations of the Trust, or as they deem
desirable to use in the conduct of its affairs or to retain for future
requirements or extensions of the business. The Trustees may adopt and offer to
Shareholders such dividend reinvestment plans, cash dividend payout plans or
related plans as the Trustees shall deem appropriate.

     Inasmuch as the computation of net income and gains for federal income tax
purposes may vary from the computation thereof on the books, the above
provisions shall be interpreted to give the Trustees the power in their
discretion to distribute for any fiscal year as ordinary dividends and as
capital gains distributions, respectively, additional amounts sufficient to
enable the Trust to avoid or reduce liability for taxes.

8.3. Power to Modify Foregoing Procedures.  Notwithstanding any of the
     ------------------------------------
foregoing provisions of this Article VIII, the Trustees may prescribe, in their
absolute discretion, such other bases and times for determining the per share
net asset value of the Trust's Shares or net income, or the declaration and
payment of dividends and distributions as they deem necessary or desirable or to
enable the Trust to comply with any provision of the 1940 Act, including any
rule or regulation adopted pursuant to the 1940 Act by the Commission or any
securities association registered under the Securities Exchange Act of 1934, all
as in effect now or hereafter amended or modified.

                                 Shareholders
                                 ------------

9.1. Voting Powers.  The Shareholders shall have power to vote only (i) for
     -------------
the election of Trustees as provided in Section 2.2 hereof, (ii) for the removal
of Trustees as provided in Section 2.2 hereof, (iii) with respect to any
investment advisory or management contract as provided in Section 4.1, (iv) with
respect to the termination of the Trust as provided in Section 10.2, (v) with
respect to any amendment of the Declaration to the extent and as provided in
Section 10.3, (vi) with respect to any merger, consolidation or sale of assets
as provided in Section 10.4, (vii) with respect to any conversion to an "open-
end" company as provided in Section 10.5, (viii) with respect to incorporation
or reorganization of the Trust to the extent and as provided in Section 10.6,
(ix) to the same extent as the stockholders of a Massachusetts business
corporation as to whether or not a court action, proceeding or claim should or
should not be brought or maintained derivatively or as a class action on behalf
of the Trust or the Shareholders, (x) with respect to such additional matters
relating to the Trust as may be required by law, the Declaration, the By-Laws or
any registration of the Trust with the Commission (or any successor agency) or
any state, or as and when the Trustees may consider necessary or desirable, and
(xi) with respect to those matters set forth in the designations and powers,
preferences and rights and the qualifications, limitations and restrictions of
the Preferred Shares, as determined in accordance with Section 6.1 hereof. Each
whole share shall be entitled to one vote as to any matter on which it is
entitled to vote and each fractional Share shall be entitled to a proportionate
fractional vote, except that Shares held in the treasury of the Trust as of the
record date, as determined in accordance with the By-Laws, shall not be voted.
There shall be no cumulative voting in the election of Trustees. Until Shares
are issued, the Trustees may exercise all rights of Shareholders and may take
any action required by law, the Declaration or the By-Laws to be taken by
Shareholders. The By-Laws may include further provisions for Shareholder's votes
and meetings and related matters.

9.2. Meetings of Shareholders.
     ------------------------

(a)  Annual Meetings.  Annual meetings of the Shareholders shall be held at
     ---------------
     such place within or without the Commonwealth of Massachusetts on such day
     and at such time as the Trustees shall designate.

(b)  Special Meetings.  Special meetings of the Shareholders may be called at
     ----------------
     any time by a majority of the, Trustees and shall be called by any Trustee
     upon written request of Shareholders holding in the aggregate not less than
     10% of the outstanding Shares having voting rights, such request specifying
     the purpose or purposes for which such meeting is to be called. Any such
     meeting shall be held within or without the Commonwealth of Massachusetts
     on such day and at such time as the Trustees shall designate.

     The holders of a majority of the outstanding Shares present in person or by
proxy shall constitute a quorum at any annual or special meeting for the
transaction of any business, except as may otherwise be required by the 1940
Act, the laws of the Commonwealth of Massachusetts or other applicable law or by
this Declaration or the By-Laws of the Trust. If a quorum is present at a
meeting, the affirmative vote of a majority of the Shares represented at the
meeting

                                       18
<PAGE>

constitutes the action of the Shareholders, unless the 1940 Act, the laws of the
Commonwealth of Massachusetts or other applicable law, the Declaration or the
By-Laws of the Trust requires a greater number of affirmative votes. If the
Shares shall be divided into classes with a class having exclusive voting rights
with respect to certain matters, the aforesaid quorum and voting requirements
with respect to action to be taken by the Shareholders of the class on such
matters shall be applicable only to the Shares of such class.

9.3. Notice of Meetings.  Notice of all meetings of the Shareholders, stating
     ------------------
the time, place and purposes of the meeting, shall be given by the Trustees by
mail to each Shareholder at his registered address, mailed at least 10 days and
not more than 60 days before the meeting. Only the business stated in the notice
of the meeting shall be considered at such meeting. Any adjourned meeting may be
held as adjourned without further notice.

9.4. Record Date for Meetings.  For the purpose of determining the
     ------------------------
Shareholders who are entitled to notice of and to vote at any meeting, or to
participate in any distribution, or for the purposes of any other action, the
Trustees may from time to time close the transfer books for such period, not
exceeding 30 days, as the Trustees may determine; or without closing the
transfer books the Trustees may fix a date not more than 60 days prior to the
date of any meeting of Shareholders or daily dividends or other action as a
record date for the determination of the Persons to be treated as Shareholders
of record for such purposes, except for dividend payments which shall be
governed by Section 8.2 hereof.

9.5. Proxies, etc.  At any meeting of Shareholders, any holder of Shares
     -------------
entitled to vote thereat may vote by proxy, provided that no proxy shall be
voted at any meeting unless it shall have been placed on file with the
Secretary, or with such other officer or agent of the Trust as the Secretary may
direct, for verification prior to the time at which such vote shall be taken.
Pursuant to a resolution of a majority of the Trustees, proxies may be solicited
in the name of one or more Trustees or one or more of the officers of the Trust.
Only Shareholders of record shall be entitled to vote. Each full Share shall be
entitled to one vote and fractional Shares shall be entitled to a vote of such
fraction. When any Share is held jointly by several persons, any one of them may
vote at any meeting in person or by proxy in respect of such Share, but if more
than one of them shall be present at such meeting in person by proxy, and such
joint owners or their proxies so present disagree as to any vote to be cast,
such vote shall not be received in respect of such Share. A proxy purporting to
be executed by or on behalf of a shareholder shall be deemed valid unless
challenged at or prior to its exercise, and the burden of proving invalidity
shall rest on the challenger. If the holder of any such Share is a minor or a
person of unsound mind, and subject to guardianship or to the legal control of
any other person as regards the charge or management of such Share, he may vote
by his guardian or such other person appointed or having such control, and such
vote may be given in person or by proxy.

9.6. Reports.  The Trustees shall cause to be prepared at least annually a
     -------
report of operations containing a balance sheet and statement of income and
undistributed income of the Trust prepared in conformity with generally accepted
accounting principles and an opinion of an independent public accountant or such
financial statements. Copies of such reports shall be mailed to all Shareholders
of record within the time required by the 1940 Act, and in any event within a
reasonable period preceding the annual meeting of Shareholders. The Trustees
shall, in addition, furnish to the Shareholders at least semi-annually interim
reports containing an

                                       19
<PAGE>

unaudited balance sheet of the Trust as of the end of such period and an
unaudited statement of income and surplus for the period from the beginning of
the current fiscal year to the end of such period.

9.7. Inspection of Records.  The records of the Trust shall be open to
     ---------------------
inspection by Shareholders to the same extent as is permitted shareholders of a
Massachusetts business corporation.

9.8. Shareholder Action by Written Consent.  Any action which may be taken by
     -------------------------------------
Shareholders may be taken without a meeting if a majority of Shareholders
entitled to vote on the matter (or such larger proportion thereof as shall be
required by any express provision of this Declaration) consent to the action in
writing and the written consents are filed with the records of the meetings of
Shareholders. Such consent shall be treated for all purposes as a vote taken at
a meeting of Shareholders.

10.2. Termination of Trust.
      --------------------

(a)   The Trust may be terminated by the affirmative of the holders of not less
      than two-thirds of the Shares at any meeting of Shareholders or if such
      termination has been approved by the affirmative vote of at least two
      thirds of the Trustees, in which case the affirmative vote of the holders

      Trust,

(i)   The Trust shall carry on no business except for the purpose of winding up
      its affairs.

(ii)  The Trustees shall proceed to wind up the affairs of the Trust and all of
      the powers of the Trustees under this Declaration shall continue until the
      affairs of the Trust shall have been wound up, including the power to
      fulfill or discharge the contracts of the Trust, collect its assets, sell,
      convey, assign, exchange, transfer or otherwise dispose of all or any part
      of the remaining Trust Property to one or more persons at public or
      private sale for consideration which may consist in whole or in part of
      cash, securities or other property of any kind, discharge or pay its
      liabilities, and do all other acts appropriate to liquidate its business.

(iii) After paying or adequately providing for the payment of all liabilities,
      and upon receipt of such releases, indemnities and refunding agreements,
      as they deem necessary for their protection, the Trustees may distribute
      the remaining Trust Property, in cash or in kind or partly each, among the
      Shareholders of each class, according to the respective rights taking into
      account the proper allocation of expenses being borne solely by any class
      of Shares.

(b)   After termination of the Trust and distribution to the Shareholders as
      herein provided, a majority of the Trustees shall execute and lodge among
      the records of the Trust an instrument in writing setting forth the fact
      of such termination, and the Trustees shall thereupon be discharged from
      all further liabilities and duties hereunder, and the rights and interests
      of all Shareholders shall thereupon cease.

10.3. Amendment Procedure.
      -------------------

(a)   Except as provided in paragraph (b) of this Section 10.3, this Declaration
      may be amended by a vote of a majority of the Shares at a meeting of
      Shareholders, or by an instrument in writing, without a meeting signed by
      a majority of the Trustees and consented to by the holders of not less
      than a majority of such Shares. The Trustees may also amend this
      Declaration without the vote or consent of Shareholders (i) to change the
      name of the Trust,

                                       21
<PAGE>

      (ii) to supply any omission, or cure, correct or supplement any ambiguous,
      defective or inconsistent provision hereof, (iii) if they deem it
      necessary to conform this Declaration to the requirements of applicable
      federal or state laws or regulations or the requirements of the Internal
      Revenue Code, or to eliminate or reduce any federal, state or local taxes
      which are or may be payable by the Trust or the Shareholders, but the
      Trustee shall not be liable for failing to do so, (iv) to make any changes
      deemed necessary to effectuate the designations and powers, preferences
      and rights, and the qualifications, limitations and restrictions adopted
      by the Trustees with respect to the Preferred Shares pursuant to Section
      6.1 hereof, or (v) for any other purpose which does not adversely affect
      the rights of any Shareholder with respect to which the amendment is or
      purports to be applicable.

(b)   No amendment may be made, under Section 10.3(a) above, which would change
      any rights with respect to any Shares of the Trust by reducing the amount
      payable thereon upon liquidation of the Trust or by diminishing or
      eliminating any voting rights pertaining thereto, except with the vote or
      consent of the holders of two-thirds of the Shares of the Trust so
      affected outstanding and entitled to vote. Nothing contained in this
      Declaration shall permit the amendment of this Declaration to impair the
      exemption from personal liability of the Shareholders, Trustees, officers,
      employees and agents of the Trust or to permit assessments upon
      Shareholders.

(c)   A certification in recordable form signed by a majority of the Trustees or
      by the Secretary or any Assistant Secretary of the Trust setting forth an
      amendment and reciting that it was duly adopted by the Shareholders or by
      the Trustees as aforesaid or a copy of the Declaration, as amended, in
      recordable form, and executed by a majority of the Trustees or certified
      by the Secretary or any Assistant Secretary of the Trust, shall be
      conclusive evidence of such amendment when lodged among the records of the
      Trust.

      Notwithstanding any other provision hereof, until such time as a
Registration Statement under the Securities Act of 1933, as amended, covering
the first public offering of Shares of the Trust shall have become effective,
this Declaration may be terminated or amended in any respect by the affirmative
vote of a majority of the Trustees or by an instrument signed by a majority of
the Trustees.

10.4. Merger, Consolidation and Sale of Assets.  Notwithstanding any other
      ----------------------------------------
provisions of this Declaration or the By-Laws of the Trust, a favorable vote of
the holders of at least two-thirds of the outstanding Shares of the Trust
entitled to be voted on the matter shall be required to approve, adopt or
authorize (i) a merger or consolidation or share exchange of the Trust with any
other entity, or (ii) a sale or exchange of all or substantially all of the
assets of the Trust (other than in the regular course of its investment
activities), unless such action has previously been approved, adopted or
authorized by the affirmative vote of at least two-thirds of the total number of
Trustees fixed in accordance with this Declaration, in which case the
affirmative vote of the holders of a majority of the outstanding Shares of the
Trust entitled to vote thereon shall be required.  In respect of any such
merger, consolidation, sale or exchange of assets, any Shareholder shall be
entitled to rights of appraisal of his Shares to the same extent as a
shareholder of a Massachusetts business corporation in respect of a merger,
consolidation, sale or exchange of assets of a Massachusetts business
corporation, and such right shall be his exclusive remedy in respect of his
dissent from any such action.

of two-thirds of the outstanding Shares of the Trust entitled to be voted on the
matter shall be required to approve, adopt or authorize an amendment to this
Declaration that makes the Common Shares a "redeemable security" (as that term
is defined in section 2(a)(32) the Investment Company Act of 1940, as amended)
unless such action has previously been approved, adopted or authorized by the
affirmative vote of at least two-thirds of the total number of Trustees fixed in
accordance with this Declaration, in which case the affirmative vote of the
holders of a majority of the outstanding Shares of the Trust entitled to vote
thereon shall be required.

10.6. Incorporation.  With the approval of the holders of a majority of the
      -------------
Shares, the Trustees may cause to be organized or assist in organizing a
corporation or corporations under the laws of any jurisdiction or any other
trust, partnership, association or other organization to take over all of the
Trust Property or to carry on any business in which the Trust shall directly or
indirectly have any interest, and to sell, convey and transfer the Trust
Property to any such corporation, trust, association or organization in exchange
for the Shares or securities thereof or otherwise, and to lend money to,
subscribe for the Shares or securities of, and enter into any contracts with any
such corporation, trust, partnership, association or organization, or any
corporation, partnership, trust, association or organization in which the Trust
holds or is about to acquire shares or any other interest. The Trustees may also
cause merger or consolidation between the Trust or any successor thereto and any
such corporation, trust, partnership, association or other organization if and
to the extent permitted by law, as provided under the law then in effect.
Nothing contained herein shall be construed as requiring approval of
Shareholders for the Trustees to organize or assist in organizing one or more
corporations, trusts, partnerships, associations or other organizations and
selling, conveying or transferring a portion of the Trust Property to such
organizations or entities.

11.6. Provisions in Conflict with Law or Regulations.
      ----------------------------------------------

(a)   The provisions of this Declaration are severable, and if the Trustees

      is in conflict with the 1940 Act, the regulated investment company
      provisions of the Internal Revenue Code or with other applicable laws and
      regulations, the conflicting provision shall be deemed never to have
      constituted a part of this Declaration; provided, however, that such
      determination shall not affect any of the remaining provisions of this
      Declaration or render invalid or improper any action taken or omitted
      prior to such determination.

(b)   If any provision of this Declaration shall be held invalid or
      unenforceable in any jurisdiction, such invalidity or unenforceability
      shall attach only to such provision in such jurisdiction and shall not in
      any manner affect such provision in any other jurisdiction or any other
      provision of this Declaration in any jurisdiction.

     When the Trust sells a Pennsylvania Municipal Bond or Municipal Bond and
agrees to repurchase it at a future date, the Discounted Value of such Bond will
constitute a Moody's Eligible Asset and the amount the Trust is required to pay
upon repurchase of such Bond will count as a liability for purposes of
calculating the AMPS Basic Maintenance Amount.  When the Trust purchases a
Pennsylvania Municipal Bond or Municipal Bond and agrees to sell it at a future
date to another party, cash receivable by the Trust thereby will constitute a
Moody's Eligible Asset if the long-term debt of such other party is rated at
least A2 by Moody's and such agreement has a term of 30 days or less; otherwise
the Discounted Value of such Bond will constitute a Moody's Eligible Asset.

     Notwithstanding the foregoing, an asset will not be considered a Moody's
Eligible Asset if it is (i) held in a margin account, (ii) subject to any
material lien, mortgage, pledge, security interest or security agreement of any
kind, (iii) held for the purchase of a security pursuant to a Forward Commitment
or (iv) irrevocably deposited by the Trust for the payment of dividends or
redemption.

Pennsylvania Municipal Bonds will be 115%, so long as such Pennsylvania
Municipal Bonds are rated A-1+ or SP-1+ by S&P and mature or have a demand
feature exercisable in 30 days or less, or 125% if such Pennsylvania Municipal
Bonds are not rated by S&P but are rated VMIG-1, P-1 or MIG-1 by Moody's;
provided, however, such short-term Pennsylvania Municipal Bonds rated by Moody's
but not rated by S&P having a demand feature exercisable in 30 days or less must
be backed by a letter of credit, liquidity facility or guarantee from a bank or
other financial institution having a short-term rating of at least A-1+ from

notes or bond anticipation notes which must be rated by S&P to be included in
S&P Eligible Assets, if not rated by S&P but rated by Moody's, is rated at least
A by Moody's (provided that such Moody's-rated Pennsylvania Municipal Bonds will
be included in S&P Eligible Assets only to the extent the Market Value of such
Pennsylvania Municipal Bonds does not exceed 50% of the aggregate Market Value
of the S&P Eligible Assets; and further provided that, for purposes of
determining the S&P Discount Factor applicable to any such Moody's-rated
Pennsylvania Municipal Bond, such Pennsylvania Municipal Bond will be deemed to
have an S&P rating which is one full rating category lower than its Moody's
rating); (iv) is not subject to a covered call or covered put option written by
the Trust; (v) is not part of a private placement of Pennsylvania Municipal
Bonds; and (vi) is part of an issue of Pennsylvania Municipal Bonds with an

     the aggregate Market Value of the S&P Eligible Assets, provided that 2% is
     added to the applicable S&P Discount Factor for every 1% by which the
     Market Value of such Pennsylvania Municipal Bonds exceeds 5% of the
     aggregate Market Value of the S&P Eligible Assets;

(2)  Pennsylvania Municipal Bonds guaranteed or insured by any one bond insurer
     will be considered S&P Eligible Assets only to the extent the fair market
     value of such Pennsylvania Municipal Bonds does not exceed 25% of the
     aggregate fair market value of the S&P Eligible Assets; and

(3)  Pennsylvania Municipal Bonds of any one issue type category (as described
     below) will be considered S&P Eligible Assets only to the extent the Market
     Value of such Bonds does not exceed 20% of the aggregate Market Value of
     S&P Eligible Assets, except that Pennsylvania Municipal Bonds falling
     within the utility issue type category will be broken down into three sub-
     categories (as described below) and such Pennsylvania Municipal Bonds will
     be considered S&P Eligible Assets to the extent the Market Value of such
     Bonds in each such sub-category does not exceed 20% of the aggregate Market
     Value of S&P Eligible Assets.  For purposes of the issue type category
     requirement described above, Pennsylvania Municipal Bonds will be

     transportation issues, industrial development bond issues, utility issues,

     irrigation, resource recovery, solid waste and other utilities, provided
     that Pennsylvania Municipal Bonds included in this sub-category (iii) must
     be rated by S&P in order to be included in S&P Eligible Assets.

the Trust in writing that such action will not adversely affect its then current
rating on the AMPS.

     "S&P Exposure Period" means the maximum period of time following a

     2.   Dividends.  (a)  The Holders shall be entitled to receive, when, as
          ---------
and if declared by the Board of Trustees of the Trust, out of funds legally
available therefor, cumulative dividends each consisting of (i) cash at the
Applicable Rate, (ii) a Right to receive cash as set forth in paragraph 2(e)
below, and (iii) any additional amounts as set forth in paragraph 2(f) below,
and no more, payable on the respective dates set forth below. Dividends on the
shares of AMPS so declared and payable shall be paid (i) in preference to and in
priority over any dividends declared and payable on the 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 Trust's investments. To the extent permitted
under the Code, dividends on shares of AMPS will be designated as exempt-
interest dividends. For the purposes of this section, the term "net tax-exempt
income" shall exclude capital gains of the Trust.

     (b) (i)  Cash dividends on shares of AMPS shall accumulate from the Date of
Original Issue and shall be payable, when, as and if declared by the Board of
Trustees, out of funds legally available therefor, commencing on the First
Initial Dividend Payment Date with respect to the AMPS.  Dividends on the AMPS
during the Initial Dividend Period shall be payable on each Initial Dividend
Payment Date, except that if any Initial Dividend Payment Date is not a Business
Day, then (i) the Dividend Payment Date shall be the first Business Day next
succeeding such Initial Dividend Payment Date if such Initial Dividend Payment
Date is a Saturday, Sunday, Monday, Tuesday, Wednesday or Thursday, or (ii) the
Dividend Payment Date shall be the first Business Day next preceding such
Initial Dividend Payment Date if such Initial Dividend Payment Date is a Friday.
If, however, in the case of clause (ii) in the preceding sentence, the
Securities Depository shall make available to its participants and members in
funds immediately available in New York City on Initial Dividend Payment Dates
the amount due as

                                       31
<PAGE>

dividends on such Initial Dividend Payment Dates (and the Securities Depository
shall have so advised the Trust), and if the day that otherwise would be the
Initial Dividend Payment Date is not a Business Day, then the Dividend Payment
Date shall be the next succeeding Business Day. Following the Last Initial
Dividend Payment Date for the AMPS, dividends on the AMPS will be payable, at
the option of the Trust, either (i) with respect to any 7-day Dividend Period
and any Short Term Dividend Period of 35 or fewer days, on the day next
succeeding the last day thereof and (ii) with respect to any Short Term Dividend
Period of more than 35 days and with respect to any Long Term Dividend Period,
monthly on the first day of each calendar month during such Short Term Dividend
Period or Long Term Dividend Period and on the day next succeeding the last day
thereof (each such date referred to in clause (i) or (ii) being herein referred
to as a "Normal Dividend Payment Date"), except that if such Normal Dividend
Payment Date is not a Business Day, then (i) the Dividend Payment Date shall be
the first Business Day next succeeding such Normal Dividend Payment Date if such
Normal Dividend Payment Date is a Saturday, Sunday, Monday, Tuesday, Wednesday
or Thursday, or (ii) the Dividend Payment Date shall be the first Business Day
next preceding such Normal Dividend Payment Date if such Normal Dividend Payment
Date is a Friday. If, however, in the case of clause,(ii) in the preceding
sentence, the Securities Depository shall make available to its participants and
members in funds immediately available in New York City on Dividend Payment
Dates the amount due as dividends on such Dividend Payment Dates (and the
Securities Depository shall have so advised the Trust), and if the Normal
Dividend Payment Date is not a Business Day, then the Dividend Payment Date
shall be the next succeeding Business Day. Although any particular Dividend
Payment Date may not occur on the originally scheduled date because of the
exceptions discussed above, the next succeeding Dividend Payment Date, subject
to such

                                       32
<PAGE>

exceptions, will occur on the next following originally scheduled date. If for
any reason a Dividend Payment Date cannot be fixed as described above, then the
Board of Directors shall fix the Dividend Payment Date. The Initial Dividend
Period, 7-day Dividend Periods and Special Dividend Periods are hereinafter
sometimes referred to as Dividend Periods. Each dividend payment date determined
as provided above is hereinafter referred to as a "Dividend Payment Date."

         (ii) Each dividend shall be paid to the Holders as they appear in the
Stock Register as of 12:00 noon, New York City time, on the Business Day
preceding the Dividend Payment Date. Dividends in arrears for any past Dividend
Period may be declared and paid at any time, without reference to any regular
Dividend Payment Date, to the Holders as they appear on the Share Register on a
date, not exceeding 15 days prior to the payment date therefor, as may be fixed
by the Board of Trustees of the Trust.

     (c) (i) During the period from and including the Date of Original Issue to
but excluding the Last Initial Dividend Payment Date (the "Initial Dividend
Period"), the Applicable Rate shall be the Initial Dividend Rate.  Commencing on
the Last Initial Dividend Payment Date, the Applicable Rate for each subsequent
dividend period (hereinafter referred to as a "Subsequent Dividend Period"),
which Subsequent Dividend Period shall commence on and include a Dividend
Payment Date and shall end on and include the calendar day prior to the next
Dividend Payment Date (or last Dividend Payment Date in a Dividend Period if
there is more than one Dividend Payment Date), shall be equal to the rate per
annum that results from implementation of the Auction Procedures.

     The Applicable Dividend Rate for each Dividend Period commencing during a
Non-Payment Period shall be equal to the Non-Payment Period Rate; and each
Dividend Period,

                                       33
<PAGE>

commencing after the first day of, and during, a Non-Payment Period shall be a
7-day Dividend Period. Except in the case of the willful failure of the Trust to
pay a Dividend on a Dividend Payment Date or to redeem any shares of AMPS on the
date set for such redemption, any amount of any dividend due on any Dividend
Payment Date (if, prior to the close of business on the second Business Day
preceding such Dividend Payment Date, the Trust has declared such dividend
payable on such Dividend Payment Date to the Holders of such shares of AMPS as
of 12:00 noon, New York City time, on the Business Day preceding such Dividend
Payment Date) or redemption price with respect to any shares of AMPS not paid to
such Holders when due may be paid to such Holders in the same form of funds by
12:00 noon, New York City time, on any of the first three Business Days after
such Dividend Payment Date or due date, as the case may be, provided that, such
amount is accompanied by a late charge calculated for such period of non-payment
at the Non-Payment Period Rate applied to the amount of such non-payment based
on the actual number of days comprising such period divided by 365. In the case
of a willful failure of the Trust to pay a dividend on a Dividend Payment Date
or to redeem any shares of AMPS on the date set for such redemption, the
preceding sentence shall not apply and the Applicable Dividend Rate for the
Dividend Period commencing during the Non-Payment Period resulting from such
failure shall be the Non-Payment Period Rate. For the purposes of the foregoing,
payment to a person in same-day funds on any Business Day at any time shall be
considered equivalent to payment to such person in New York Clearing House
(next-day) funds at the same time on the preceding Business Day, and any payment
made after 12:00 noon, New York City time, on any Business Day shall be
considered to have been made instead in the same form of funds and to the same
person before 12:00 noon, New York City time, on the next Business Day.

                                       34
<PAGE>

         (ii) The amount of cash dividends per share of AMPS payable (if
declared) on each Dividend Payment Date of the Initial Dividend Period, each 7-
day Dividend Period and each Short Term Dividend Period shall be computed by
multiplying the Applicable Rate for such Dividend Period by a fraction, the
numerator of which will be the number of days in such Dividend Period such share
was outstanding and the denominator of which will be 365, multiplying the amount
so obtained by $50,000, and rounding the amount so obtained to the nearest cent.
During any Long Term Dividend Period, the amount of dividends per share payable
on any Dividend Payment Date shall be computed on the basis of a year consisting
of twelve 30-day months.

         (iii) With respect to each Dividend Period that is a Special Dividend
Period, the Trust may, at its sole option and to the extent permitted by law, by
telephonic and written notice (a "Request for Special Dividend Period") to the
Auction Agent and to each Broker-Dealer, request that the next succeeding
Dividend Period for the AMPS be the number of days (other than 7) evenly
divisible by seven, and not fewer than seven or more than 364 in the case of a
Short Term Dividend Period or one whole year or more but not greater than five
years in the case of a Long Term Dividend Period, specified in such notice,
provided that the Trust may not give a Request for Special Dividend Period of
greater than 28 days (and any such request shall be null and void) unless the
Trust has given written notice thereof to S&P and received written confirmation
from Moody's that such action would not impair the ratings then assigned to the
AMPS by Moody's and unless, for any Auction occurring after the initial Auction,
Sufficient Clearing Bids were made in the last occurring Auction and unless full
cumulative dividends, any amounts due with respect to redemptions, and any
Additional Dividends payable prior to such date have been paid in full. Such
Request for Special Dividend
                                       35
<PAGE>

Period, in the case of a Short Term Dividend Period, shall be given on or prior
to the fourth Business Day but not more than seven Business Days prior to an
Auction Date for AMPS and, in the case of a Long Term Dividend Period, shall be
given on or prior to the 14th day but not more than 28 days prior to an Auction
Date for the AMPS. Upon receiving such Request for Special Dividend Period, the
Broker-Dealer(s) shall jointly determine whether, given the factors set forth
below, it is advisable that the Trust issue a Notice of Special Dividend Period
for the AMPS as contemplated by such Request for Special Dividend Period and the
Optional Redemption Price of the AMPS during such Special Dividend Period and
the Specific Redemption Provisions and shall give the Trust and the Auction
Agent written notice (a "Response") of such determination by no later than the
third Business Day prior to such Auction Date. In making such determination the
Broker-Dealer(s) will consider (1) existing short-term and long-term market
rates and indices of such short-term and long-term rates, (2) existing market
supply and demand for short-term and long-term securities, (3) existing yield
curves for short-term and long-term securities comparable to the AMPS, (4)
industry and financial conditions which may affect the AMPS, (5) the investment
objective of the Trust, and (6) the Dividend Periods and dividend rates at which
current and potential beneficial holders of the AMPS would remain or become
beneficial holders. If the Broker-Dealer(s) shall not give the Trust and the
Auction Agent a Response by such third Business Day or if the Response states
that given the factors set forth above it is not advisable that the Trust give a
Notice of Special Dividend Period for the AMPS, the Trust may not give a Notice
of Special Dividend Period in respect of such Request for Special Dividend
Period. In the event the Response indicates that it is advisable that the Trust
give a Notice of special Dividend Period for the AMPS, the Trust may by no later
than the second Business Day prior to such Auction Date give a notice of its
revocation (a "Notice of

                                       36
<PAGE>

Special Dividend Period") to the Auction Agent, the Securities Depository and
each Broker-Dealer which notice will specify (i) the duration of the Special
Dividend Period, (ii) the Optional Redemption Price as specified in the related
Response and (iii) the Specific Redemption Provisions, if any, as specified in
the related Response.  The Trust shall not give a Notice of Special Dividend
Period and, if the Trust has given a Notice of Special Dividend Period, the
Trust is required to give telephonic and written notice of its revocation (a
"Notice of Revocation") to the Auction Agent, each Broker-Dealer, and the
Securities Depository on or prior to the Business Day prior to the relevant
Auction Date if (x) either the 1940 Act AMPS Asset Coverage is not satisfied or
the Trust shall fail to maintain S&P Eligible Assets and Moody's Eligible Assets
each with an aggregate Discounted Value at least equal to the AMPS Basic
Maintenance Amount, in each case on each of the two Valuation Dates immediately
preceding the Business Day prior to the relevant Auction Date on an actual basis
and on a pro forma basis giving effect to the proposed Special Dividend Period
(using as a pro forma dividend rate with respect to such Special Dividend Period
the dividend rate which the Broker-Dealers shall advise the Trust is an
approximately equal rate for securities similar to the AMPS with an equal
dividend period), provided that, in calculating the aggregate Discounted Value
of Moody's Eligible Assets for this purpose, the Moody's Exposure Period shall
be deemed to be one week longer, (y) sufficient funds for the payment of
dividends payable on the immediately succeeding Dividend Payment Date have not
been irrevocably deposited with the Auction Agent by the close of business on
the third Business Day preceding the related Auction Date or (z) the Broker-
Dealer(s) jointly advise the Trust that after consideration of the factors
listed above they have concluded that it is advisable to give a Notice of
Revocation.  If the Trust is prohibited from giving a Notice of Special Dividend
Period as a result of any of the factors enumerated in clause

                                       37
<PAGE>

(x), (y) or (z) of the prior sentence or if the Trust gives a Notice of
Revocation with respect to a Notice of Special Dividend Period for the AMPS, the
next succeeding Dividend Period will be a 7-day Dividend Period. In addition, in
the event Sufficient Clearing Bids are not made in the applicable Auction or
such Auction is not held for any reason, such next succeeding Dividend Period
will be a 7-day Dividend Period and the Trust may not again give a Notice of
Special Dividend Period for the AMPS (and any such attempted notice shall be
null and void) until Sufficient Clearing Bids have been made in an Auction with
respect to a 7-day Dividend Period.

     (d) (i)  Holders shall not be entitled to any dividends, whether payable in
cash, property or shares of beneficial interest, in excess of full cumulative
dividends and applicable late charge, as herein provided, on the shares of AMPS
(except for Additional Dividends as provided in paragraph 2(e) hereof).  Except
for the late charge payable pursuant to paragraph 2(c)(i) hereof, no interest,
or sum of money in lieu of interest, shall be payable in respect of any dividend
payment on the shares of AMPS that may be in arrears.

         (ii) For so long as any share of AMPS is Outstanding, the Trust shall
not declare, pay or set apart for payment any dividend or other distribution
(other than a dividend or distribution paid in shares of, or options, warrants
or rights to subscribe for or purchase, Common Shares or other shares of
beneficial interest, if any, ranking junior to the shares of AMPS as to
dividends or upon liquidation) in respect of the Common Shares or any other
shares of beneficial interest of the Trust ranking junior to or on a parity with
the shares of AMPS as to dividends or upon liquidation, or call for redemption,
redeem, purchase or otherwise acquire for consideration any of the Common Shares
or any other such junior shares of beneficial interest (except by conversion
into or exchange for shares of the Trust ranking junior to the shares of AMPS as
to dividends and upon liquidation) or any other such Parity Shares (except by

                                       38
<PAGE>

conversion into or exchange for shares of beneficial interest of the Trust
ranking junior to or on a parity with the shares of AMPS as to dividends and
upon liquidation), unless (A) immediately after such transaction, the Trust
shall have S&P Eligible Assets and Moody's Eligible Assets each with an
aggregate Discounted Value equal to or greater than the AMPS Basic Maintenance
Amount and the Trust shall maintain the 1940 Act AMPS Asset Coverage, (B) full
cumulative dividends on shares of AMPS and shares of Other AMPS due on or prior
to the date of the transaction have been declared and paid or shall have been
declared and sufficient funds for the payment thereof deposited with the Auction
Agent, (C) any Additional Dividend required to be paid under paragraph 2(e)
below on or before the date of such declaration or payment has been paid and (D)
the Trust has redeemed the full number of shares of AMPS required to be redeemed
by any provision for mandatory redemption contained herein.

     (e) Each dividend shall consist of (i) cash at the Applicable Dividend
Rate, (ii) an uncertificated right (a "Right") to receive an Additional Dividend
(as defined below), and (iii) any additional amounts as set forth in paragraph
2(f) below. Each Right shall thereafter be independent of the share or shares of
AMPS on which the dividend was paid. The Trust shall cause to be maintained a
record of each Right received by the respective Holders. A Right may not be
transferred other than by operation of law. If the Trust retroactively allocates
any net capital gains or other income subject to regular Federal income taxes to
shares of AMPS without having given advance notice thereof to the Auction Agent
as described in paragraph 2(f) hereof solely by reason of the fact that such
allocation is made as a result of the redemption of all or a portion of the
outstanding shares of AMPS or the liquidation of the Trust (the amount of such
allocation referred to herein as a "Retroactive Taxable Allocation"), the Trust
will, within 90 days (and generally within 60 days) after the end of the Trust's
fiscal year for which a
                                       39
<PAGE>

Retroactive Taxable Allocation is made, provide notice thereof to the Auction
Agent and to each holder of a Right applicable to such shares of AMPS (initially
Cede & Co. as nominee of the Depository Trust Company) during such fiscal year
at such holder's address as the same appears or last appeared on the Share Books
of the Trust. The Trust will, within 30 days after such notice is given to the
Auction Agent, pay to the Auction Agent (who will then distribute to such
holders of Rights), out of funds legally available therefor, an amount equal to
the aggregate Additional Dividend with respect to all Retroactive Taxable
Allocations made to such holders during the fiscal year in question.

     An "Additional Dividend" means payment to a present or former holder of
shares of AMPS of an amount which, when taken together with the aggregate amount
of Retroactive Taxable Allocations made to such holder with respect to the
fiscal year in question, would cause such holder's dividends in dollars (after
Federal and Pennsylvania income tax consequences) from the aggregate of both the
Retroactive Taxable Allocations and the Additional Dividend to be equal to the
dollar amount of the dividends which would have been received by such holder if
the amount of the aggregate Retroactive Taxable Allocations would have been
excludable from the gross income of such holder.  Such Additional Dividend shall
be calculated (i) without consideration being given to the time value of money;
(ii) assuming that no holder of shares of AMPS is subject to the Federal
alternative minimum tax with respect to dividends received from the Trust; and
(iii) assuming that each Retroactive Taxable Allocation would be taxable in the
hands of each holder of shares of AMPS at the greater of:  (x) the maximum
combined marginal regular Federal and Pennsylvania individual income tax rate
applicable to ordinary income; or (y) the maximum combined marginal regular
Federal and Pennsylvania corporate income tax rate

                                       40
<PAGE>

(taking into account the Federal income tax deductibility of state taxes paid or
incurred but not any phase out of personal exemptions, itemized deductions, or
the benefit of lower tax brackets).

     (f) Except as provided below, whenever the Trust intends to include any net
capital gains or other income subject to regular Federal income taxes in any
dividend on shares of AMPS, the Trust will notify the Auction Agent of the
amount to be so included at least five Business Days prior to the Auction Date
on which the Applicable Rate for such dividend is to be established. The Trust
may also include such income in a dividend on shares of AMPS without giving
advance notice thereof if it increases the dividend by an additional amount
calculated as if such income was a Retroactive Taxable Allocation and the
additional amount was an Additional Dividend, provided that the Trust will
notify the Auction Agent of the additional amounts to be included in such
dividend at least five Business Days prior to the applicable Dividend Payment
Date.

     (g)  No fractional shares of AMPS shall be issued.

     3. Liquidation Rights. Upon any liquidation, dissolution or winding up of
        ------------------
the Trust, whether voluntary or involuntary, the Holders shall be entitled to
receive, out of the assets of the Trust available for distribution to
shareholders, before any distribution or payment is made upon any Common Shares
or any other shares of beneficial interest ranking junior in right of payment
upon liquidation to the AMPS, the sum of $50,000 per share plus accumulated but
unpaid dividends (whether or not earned or declared) thereon to date of
distribution, and after such payment the holders of AMPS will be entitled to no
other payments other than Additional Dividends as provided in paragraph 2(e)
hereof. If upon any liquidation, dissolution or winding up of the Trust, the
amounts payable with respect to the AMPS and any other outstanding class or
series of Preferred Shares of the Trust ranking on a parity with the AMPS as to
payment upon
                                       41
<PAGE>

liquidation are not paid in full, the Holders and the holders of such other
class or series will share ratably in any such distribution of assets in
proportion to the respective preferential amounts to which they are entitled.
After payment of the full amount of the liquidating distribution to which they
are entitled, the Holders will not be entitled to any further participation in
any distribution of assets by the Trust except for any Additional Dividends. A
consolidation, merger or share exchange of the Trust with or into any other
entity 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 Trust shall not be
deemed or construed to be a liquidation, dissolution or winding up of the Trust.

     4.  Redemption.  (a)  Shares of AMPS shall be redeemable by the Trust as
         ----------
provided below:

         (i) To the extent permitted under the 1940 Act, upon giving a Notice of
Redemption, the Trust at its option may redeem shares of AMPS, in whole or in
part, out of funds legally available therefor, at the Optional Redemption Price
per share, on any Dividend Payment Date; provided that no share of AMPS may be
redeemed at the option of the Trust during (A) the Initial Dividend Period with
respect to such share or (B) a Non-Call Period to which such share is subject.
In addition, holders of AMPS which are redeemed shall be entitled to receive
Additional Dividends to the extent provided herein. The Trust may not give a
Notice of Redemption relating to an optional redemption as described in this
paragraph 4(a)(i) unless, at the time of giving such Notice of Redemption, the
Trust has available Deposit Securities with maturity or tender dates not later
than the day preceding the applicable redemption date and having a value not
less than the amount due to Holders by reason of the redemption of their shares
of AMPS on such redemption date.

         (ii) The Trust shall redeem, out of funds legally available therefor,
at the Mandatory Redemption Price per share, shares of AMPS to the extent
permitted under the 1940 Act, on a date fixed by the Board of Trustees, if the
Trust fails to maintain S&P Eligible Assets and Moody's Eligible Assets each
with an aggregate Discounted Value equal to or greater than the AMPS Basic
Maintenance Amount as provided in paragraph 7(a) or to satisfy the 1940 Act AMPS
Asset Coverage as provided in paragraph 6 and such failure is not cured on or
before the AMPS Basic Maintenance Cure Date or the 1940 Act Cure Date (herein
respectively referred to as a "Cure Date"), as the case may be. In addition,
holders of AMPS so redeemed shall be entitled to receive Additional Dividends to
the extent provided herein. The number of shares of AMPS to be redeemed shall be
equal to the lesser of (i) the minimum number of shares of AMPS the redemption
of which, if deemed to have occurred immediately prior to the opening of
business on the Cure Date, together with all shares of other Preferred Shares
subject to redemption or retirement, would result in the Trust having S&P
Eligible Assets and Moody's Eligible Assets each with an aggregate Discounted
Value equal to or greater than the AMPS Basic Maintenance Amount or satisfaction
of the 1940 Act AMPS Asset Coverage, as the case may be, on such Cure Date
(provided that, if there is no such minimum number of shares of AMPS and other
Preferred Shares the redemption of which would have such result, all shares of
AMPS and other Preferred Shares then Outstanding shall be redeemed), and (ii)
the maximum number of shares of AMPS, together with all other Preferred Shares
subject to redemption or retirement, that can be redeemed out of funds expected
to be legally available therefor on such redemption date. In determining the
number of shares of AMPS required to be redeemed in accordance with the
foregoing, the Trust shall allocate the number required to be redeemed which
would result in the Trust having S&P Eligible Assets and Moody's Eligible Assets
each
                                       43
<PAGE>

with an aggregate Discounted Value equal to or greater than the AMPS Basic
Maintenance Amount or satisfaction of the 1940 Act AMPS Asset Coverage, as the
case may be, pro rata among shares of AMPS, Other AMPS and other Preferred
Shares subject to redemption pursuant to provisions similar to those contained
in this paragraph 4(a)(ii); provided that, shares of AMPS which may not be
redeemed at the option of the Trust due to the designation of a Non-Call Period
applicable to such shares (A) will be subject to mandatory redemption only to
the extent that other shares are not available to satisfy the number of shares
required to be redeemed and (B) will be selected for redemption in an ascending
order of outstanding number of days in the Non-Call Period (with shares with the
lowest number of days to be redeemed first) and by lot in the event of shares
having an equal number of days in such Non-Call Period. The Trust shall effect
such redemption on a Business Day which is not later than 35 days after such
Cure Date, except that if the Trust does not have funds legally available for
the redemption of all of the required number of shares of AMPS and other
Preferred Shares which are subject to mandatory redemption or the Trust
otherwise is unable to effect such redemption on or prior to 35 days after such
Cure Date, the Trust shall redeem those shares of AMPS which it is unable to
redeem on the earliest practicable date on which it is able to effect such
redemption out of funds legally available therefor.

     (b) Notwithstanding any other provision of this paragraph 4, no shares of
AMPS may be redeemed pursuant to paragraph 4(a)(i) of this Certificate of
Designation (i) unless all dividends in arrears on all remaining outstanding
Parity Shares shall have been or are being contemporaneously paid or declared
and set apart for payment and (ii) if redemption thereof would result in the
Trust's failure to maintain Moody's Eligible Assets or S&P Eligible Assets with
an aggregate Discounted Value equal to or greater than the AMPS Basic
Maintenance
                                       44
<PAGE>

Amount. In the event that less than all the outstanding shares of a series of
AMPS are to be redeemed and there is more than one Holder, the shares of that
series of AMPS to be redeemed shall be selected by lot or such other method as
the Trust shall deem fair and equitable.

     (c) Whenever shares of AMPS are to be redeemed, the Trust, not less than 20
nor more than 30 days prior to the date fixed for redemption, shall mail a
notice ("Notice of Redemption") by first-class mail, postage prepaid, to each
Holder of shares of AMPS to be redeemed and to the Auction Agent. The Trust
shall cause the Notice of Redemption to also be published in the eastern and
national editions of The Wall Street Journal. The Notice of Redemption shall set
forth (i) the redemption date, (ii) the amount of the redemption price, (iii)
the aggregate number of shares of AMPS to be redeemed, (iv) the place or places
where shares of AMPS are to be surrendered for payment of the redemption price,
(v) a statement that dividends on the shares to be redeemed shall cease to
accumulate on such redemption date (except that holders may be entitled to
Additional Dividends) and (vi) the provision of this Certificate of Designation
pursuant to which such shares are being redeemed. No defect in the Notice of
Redemption or in the mailing or publication thereof shall affect the validity of
the redemption proceedings, except as required by applicable law.

     If the Notice of Redemption shall have been given as aforesaid and,
concurrently or thereafter, the Trust shall have deposited in trust with the
Auction Agent a cash amount equal to the redemption payment for the shares of
AMPS as to which such Notice of Redemption has been given with irrevocable
instructions and authority to pay the redemption price to the Holders of such
shares, then upon the date of such deposit or, if no such deposit is made, then
upon such date fixed for redemption (unless the Trust shall default in making
the redemption payment), all rights of the Holders of such shares as
shareholders of the Trust by reason of the ownership of

                                       45
<PAGE>

such shares will cease and terminate (except their right to receive the
redemption price in respect thereof and any Additional Dividends, but without
interest), and such shares shall no longer be deemed outstanding. The Trust
shall be entitled to receive, from time to time, from the Auction Agent the
interest, if any, on such moneys deposited with it and the Holders of any shares
so redeemed shall have no claim to any of such interest. In case the Holder of
any shares so called for redemption shall not claim the redemption payment for
his shares within one year after the date of redemption, the Auction Agent
shall, upon demand, pay over to the Trust such amount remaining on deposit and
the Auction Agent shall thereupon be relieved of all responsibility to the
Holder of such shares called for redemption and such Holder thereafter shall
look only to the Trust for the redemption payment.

     5.  Voting Rights.  (a)  General.  Except as otherwise provided in the
         -------------        -------
Declaration or By-Laws, each Holder of shares of AMPS shall be entitled to one
vote for each share held on each matter submitted to a vote of shareholders of
the Trust, and the holders of outstanding Preferred Shares, including AMPS, and
of Common Shares shall vote together as a single class; provided that, at any
meeting of the shareholders of the Trust held for the election of trustees, the
holders of outstanding Preferred Shares, including AMPS, shall be entitled, as a
class, to the exclusion of the holders of all other securities and classes of
shares of beneficial interest of the Trust, to elect two trustees of the Trust.
Subject to paragraph 5(b) hereof, the holders of outstanding shares of
beneficial interest of the Trust, including the holders of outstanding Preferred
Shares, including AMPS, voting as a single class, shall elect the balance of the
trustees.

     (b) Right to Elect Majority of Board of Trustees. During any period in
         --------------------------------------------
which any one or more of the conditions described below shall exist (such period
being referred to herein as a "Voting Period"), the number of trustees
constituting the Board of Trustees shall be

                                       46
<PAGE>

automatically increased by the smallest number that, when added to the two
trustees elected exclusively by the holders of Preferred Shares, would
constitute a majority of the Board of Trustees as so increased by such smallest
number; and the holders of Preferred Shares shall be entitled, voting separately
as one class (to the exclusion of the holders of all other securities and
classes of shares of beneficial interest of the Trust), to elect such smallest
number of additional trustees, together with the two trustees that such holders
are in any event entitled to elect. A Voting Period shall commence:

         (i) if at any time accumulated dividends (whether or not earned or
     declared, and whether or not funds are then legally available in an amount
     sufficient therefor) on the outstanding shares of AMPS equal to at least
     two full years' dividends shall be due and unpaid and sufficient cash or
     specified securities shall not have been deposited with the Auction Agent
     for the payment of such accumulated dividends; or

        (ii) if at any time holders of any other Preferred Shares are entitled
     to elect a majority of the trustees of the Trust under the 1940 Act.

     Upon the termination of a Voting Period, the voting rights described in
this paragraph 5(b) shall cease, subject always, however, to the reverting of
such voting rights in the Holders upon the further occurrence of any of the
events described in this paragraph 5(b).

        (c) Right to Vote with Respect to Certain Other Matters. So long as any
            ---------------------------------------------------
shares of AMPS are outstanding, the Trust shall not, without the affirmative
vote of the holders of a majority of the Preferred Shares Outstanding at the
time, voting separately as one class: (i) authorize, create or issue, or
increase the authorized or issued amount of, any class or series of shares
ranking prior to or on a parity with any series of Preferred Shares with respect
to payment of dividends or the distribution of assets on liquidation, or
increase the authorized amount of

                                       47
<PAGE>

AMPS or any other Preferred Shares, or (ii) amend, alter or repeal the
provisions of the Declaration, whether by merger, consolidation or otherwise, so
as to adversely affect any of the contract rights expressly set forth in the
Declaration of holders of shares of AMPS or any other Preferred Shares. To the
extent permitted under the 1940 Act, in the event shares of more than one series
of AMPS are outstanding, the Trust shall not approve any of the actions set
forth in clause (i) or (ii) which adversely affects the contract rights
expressly set forth in the Declaration of a Holder of shares of a series of AMPS
differently than those of a Holder of shares of any other series of AMPS without
the affirmative vote of the holders of at least a majority of the shares of AMPS
of each series adversely affected and outstanding at such time (each such
adversely affected series voting separately as a class). The Trust shall notify
Moody's and S&P ten Business Days prior to any such vote described in clause (i)
or (ii). Unless a higher percentage is provided for under the Declaration, the
affirmative vote of the holders of a majority of the outstanding Preferred
Shares, including AMPS, voting together as a single class, will be required to
approve any plan of reorganization (including bankruptcy proceedings) adversely
affecting such shares or any action requiring a vote of security holders under
Section 13(a) of the 1940 Act. The class vote of holders of Preferred Shares,
including AMPS, described above will in each case be in addition to a separate
vote of the requisite percentage of Common Shares and Preferred Shares,
including AMPS, voting together as a single class necessary to authorize the
action in question.

     (d)  Voting Procedures.
          -----------------

         (i) As soon as practicable after the accrual of any right of the
holders of Preferred Shares to elect additional trustees as described in
paragraph 5(b) above, the Trust shall call a special meeting of such holders and
instruct the Auction Agent to mail a notice of such

                                       48
<PAGE>

special meeting to such holders, such meeting to be held not less than 10 nor
more than 20 days after the date of mailing of such notice. If the Trust fails
to send such notice to the Auction Agent or if the Trust does not call such a
special meeting, it may be called by any such holder on like notice. The record
date for determining the holders entitled to notice of and to vote at such
special meeting shall be the close of business on the fifth Business Day
preceding the day on which such notice is mailed. At any such special meeting
and at each meeting held during a Voting Period, such Holders, voting together
as a class (to the exclusion of the holders of all other securities and classes
of shares of beneficial interest of the Trust), shall be entitled to elect the
number of trustees prescribed in paragraph 5(b) above. At any such meeting or
adjournment thereof in the absence of a quorum, a majority of such holders
present in person or by proxy shall have the power to adjourn the meeting
without notice, other than by an announcement at the meeting, to a date not more
than 120 days after the original record date.

         (ii) For purposes of determining any rights of the Holders to vote on
any matter or the number of shares required to constitute a quorum, whether such
right is created by this Certificate of Designation, by the other provisions of
the Declaration, by statute or otherwise, a share of AMPS which is not
Outstanding shall not be counted.

         (iii) The terms of office of all persons who are trustees of the Trust
at the time of a special meeting of Holders and holders of other Preferred
Shares to elect trustees shall continue, notwithstanding the election at such
meeting by the Holders and such other holders of the number of trustees that
they are entitled to elect, and the persons so elected by the Holders and such
other holders, together with the two incumbent trustees elected by the Holders
and such other holders of Preferred Shares and the remaining incumbent trustees
elected by the holders of the Common Shares and Preferred Shares, shall
constitute the duly elected trustees of the Trust.

                                       49
<PAGE>

         (iv) Simultaneously with the expiration of a Voting Period, the terms
of office of the additional trustees elected by the Holders and holders of other
Preferred Shares pursuant to paragraph 5(b) above shall terminate, the remaining
trustees shall constitute the trustee's of the Trust and the voting rights of
the Holders and such other holders to elect additional trustees pursuant to
paragraph 5(b) above shall cease, subject to the provisions of the last sentence
of paragraph 5(b)(ii).

     (e) Exclusive Remedy. Unless otherwise required by law, the Holders of
         ----------------
shares of AMPS shall not have any rights or preferences other than those
specifically set forth herein. The Holders of shares of AMPS shall have no
preemptive rights or rights to cumulative voting. In the event that the Trust
fails to pay any dividends on the shares of AMPS, the exclusive remedy of the
Holders shall be the right to vote for directors pursuant to the provisions of
this paragraph 5.

     (f) Notification to S&P and Moody's. In the event a vote of Holders of AMPS
         -------------------------------
is required pursuant to the provisions of Section 13(a) of the 1940 Act, the
Trust shall, not later than ten Business Days prior to the date on which such
vote is to be taken, notify S&P and Moody's that such vote is to be taken and
the nature of the action with respect to which such vote is to be taken and, not
later than ten Business Days after the date on which such vote is taken, notify
S&P and Moody's of the result of such vote.

        6. 1940 Act AMPS Asset Coverage. The Trust shall maintain, as of the
           ----------------------------
last Business Day of each month in which any share of AMPS is outstanding, the
1940 Act AMPS Asset Coverage.

     7.  AMPS Basic Maintenance Amount.   (a)  The Trust shall maintain, on each
         -----------------------------
Valuation Date, and shall verify to its satisfaction that it is maintaining on
such Valuation Date,

                                       50
<PAGE>

(i) S&P Eligible Assets having an aggregate Discounted Value equal to or greater
than the AMPS Basic Maintenance Amount and (ii) Moody's Eligible Assets having
an aggregate Discounted Value equal to or greater than the AMPS Basic
Maintenance Amount. Upon any failure to maintain the required Discounted Value,
the Trust will use its best efforts to alter the composition of its portfolio to
reattain the AMPS Basic Maintenance Amount on or prior to the AMPS Basic
Maintenance Cure Date.

     (b) On or before 5:00 p.m., New York City time, on the third Business Day
after a Valuation Date on which the Trust fails to satisfy the AMPS Basic
Maintenance Amount, the Trust shall complete and deliver to the Auction Agent,
and Moody's and S&P, as the case may be, a complete AMPS Basic Maintenance
Report as of the date of such failure, which will be deemed to have been
delivered to the Auction Agent if the Auction Agent receives a copy or telecopy,
telex or other electronic transcription thereof and on the same day the Trust
mails to the Auction Agent for delivery on the next Business Day the complete
AMPS Basic Maintenance Report. The Trust will deliver an AMPS Basic Maintenance
Report to the Auction Agent and Moody's and S&P, as the case may be, on or
before 5:00 p.m., New York City time, on the third Business Day after a
Valuation Date on which the Trust cures its failure to maintain Moody's Eligible
Assets or S&P Eligible Assets, as the case may be, with an aggregate Discounted
Value equal to or greater than the AMPS Basic Maintenance Amounts or on which
the Trust fails to maintain Moody's Eligible Assets or S&P Eligible Assets, as
the case may be, with an aggregate Discounted Value which exceeds the AMPS Basic
Maintenance Amount by 5% or more. The Trust will also deliver an AMPS Basic
Maintenance Report to the Auction Agent, Moody's and S&P as of each Quarterly
Valuation Date on or before the third Business Day after such date.
Additionally, on or before 5:00 p.m., New York City time, on the third Business
Day after the
                                       51
<PAGE>

first day of a Special Dividend Period, the Trust will deliver an AMPS Basic
Maintenance Report to S&P and the Auction Agent. Whenever the Trust delivers an
AMPS Basic Maintenance Report to S&P pursuant to this paragraph 7(b), it shall
also deliver a Certificate of Minimum Liquidity to S&P and the Auction Agent.
The Trust shall also provide Moody's and S&P with an AMPS Basic Maintenance
Report when specifically requested by either Moody's or S&P. A failure by the
Trust to deliver an AMPS Basic Maintenance Report under this paragraph 7(b)
shall be deemed to be delivery of an AMPS Basic Maintenance Report indicating
the Discounted Value for S&P Eligible Assets and Moody's Eligible Assets of the
Trust is less than the AMPS Basic Maintenance Amount, as of the relevant
Valuation Date.

     (c) Within ten Business Days after the date of delivery of an AMPS Basic
Maintenance Report and a Certificate of Minimum Liquidity in accordance with
paragraph 7(b) above relating to a Quarterly Valuation Date, the Independent
Accountant will confirm in writing to the Auction Agent, S&P and Moody's (i) the
mathematical accuracy of the calculations reflected in such Report (and in any
other AMPS Basic Maintenance Report, randomly selected by the Independent
Accountant, that was delivered by the Trust during the quarter ending on such
Quarterly Valuation Date) and (with respect to S&P only while S&P is rating the
AMPS) such Certificate, (ii) that, in such Report (and in such randomly selected
Report), the Trust correctly determined the assets of the Trust which constitute
S&P Eligible Assets or Moody's Eligible Assets, as the case may be, at such
Quarterly Valuation Date in accordance with this Certificate of Designation,
(iii) that, in such Report (and in such randomly selected Report), the Trust
determined whether the Trust had, at such Quarterly Valuation Date (and at the
Valuation Date addressed in such randomly-selected Report) in accordance with
this Certificate of Designation, S&P Eligible Assets of an aggregate Discounted
Value at least equal to the AMPS
                                       52
<PAGE>

     Basic Maintenance Amount and Moody's Eligible Assets of an aggregate
     Discounted Value at least equal to the AMPS Basic Maintenance Amount, (iv)
     that (with respect to S&P only) in such Certificate, the Trust determined
     the Minimum Liquidity Level and the Trust's Deposit Securities in
     accordance with this Certificate of Designation, including maturity or
     tender date, (v) with respect to the S&P rating on Pennsylvania Municipal
     Bonds or Municipal Bonds, the issuer name, issue size and coupon rate
     listed in such Report and (with respect to S&P only) such Certificate, that
     the Independent Accountant has requested that S&P verify such information
     and the Independent Accountant shall provide a listing in its letter of any
     differences, (vi) with respect to the Moody's ratings on Pennsylvania
     Municipal Bonds or Municipal Bonds, the issuer name, issue size and coupon
     rate listed in such Report and (with respect to S&P only) such Certificate,
     that such information has been verified by Moody's (in the event such
     information is not verified by Moody's, the Independent Accountant will
     inquire of Moody's what such information is, and provide a listing in its
     letter of any differences), (vii) with respect to the bid or mean price (or
     such alternative permissible factor used in calculating the Market Value)
     provided by the custodian of the Trust's assets to the Trust for purposes
     of valuing securities in the Trust's portfolio, the Independent Accountant
     has traced the price used in such Report and (with respect to S&P only)
     such Certificate to the bid or mean price listed in such Report and (with
     respect to S&P only) such Certificate as provided to the Trust and verified
     that such information agrees (in the event such information does not agree,
     the Independent Accountant will provide a listing in its letter of such
     differences) and (viii) with respect to such confirmation to Moody's, that
     the Trust has satisfied the requirements of paragraph 9(b) of this
     Certificate of Designation (such confirmation is herein called the
     "Accountant's Confirmation").

                                       53
<PAGE>

     (d) Within ten Business Days after the date of delivery to the Auction
Agent, S&P and Moody's of an AMPS Basic Maintenance Report in accordance with
paragraph 7(b) above relating to any Valuation Date on which the Trust failed to
maintain S&P Eligible Assets with an aggregate Discounted Value and Moody's
Eligible Assets with an aggregate Discounted Value equal to or greater than the
AMPS Basic Maintenance Amount, and relating to the AMPS Basic Maintenance Cure
Date with respect to such failure, the Independent Accountant will provide to
the Auction Agent, S&P and Moody's an Accountant's Confirmation as to such AMPS
Basic Maintenance Report.

     (e) If any Accountant's Confirmation delivered pursuant to subparagraph (c)
or (d) of this paragraph 7 shows that an error was made in the AMPS Basic
Maintenance Report for a particular Valuation Date for which such Accountant's
Confirmation as required to be delivered, or shows that a lower aggregate
Discounted Value for the aggregate of all S&P Eligible Assets or Moody's
Eligible Assets, as the case may be, of the Trust was determined by the
Independent Accountant, the calculation or determination made by such
Independent Accountant shall be final and conclusive and shall be binding on the
Trust, and the Trust shall accordingly amend and deliver the AMPS Basic
Maintenance Report to the Auction Agent, S&P and Moody's promptly following
receipt by the Trust of such Accountant's Confirmation.

     (f) On or before 5:00 p.m., New York City time, on the first Business Day
after the Date of Original Issue of the shares of AMPS, the Trust will complete
and deliver to S&P and Moody's an AMPS Basic Maintenance Report as of the close
of business on such Date of Original Issue. Within five Business Days of such
Date of Original Issue, the Independent Accountant will confirm in writing to
S&P and Moody's (i) the mathematical accuracy of the calculations reflected in
such Report and (ii) that the aggregate Discounted Value of S&P

                                       54
<PAGE>

Eligible Assets and the aggregate Discounted Value of Moody's Eligible Assets
reflected thereon equals or exceeds the AMPS Basic Maintenance Amount reflected
thereon. Also, on or before 5:00 p.m., New York City time, on the first Business
Day after Common Shares are repurchased by the Trust, the Trust will complete
and deliver to S&P and Moody's an AMPS Basic Maintenance Report as of the close
of business on such date that Common Shares are repurchased.

     (g) For so long as shares of AMPS are rated by Moody's, in managing the
Trust's portfolio, the Adviser will not alter the composition of the Trust's
portfolio if, in the reasonable belief of the Adviser, the effect of any such
alteration would be to cause the Trust to have Moody's Eligible Assets with an
aggregate Discounted Value, as of the immediately preceding Valuation Date, less
than the AMPS Basic Maintenance Amount as of such Valuation Date; provided,
however, that in the event that, as of the immediately preceding Valuation Date,
the aggregate Discounted Value of Moody's Eligible Assets exceeded the AMPS
Basic Maintenance Amount by five percent or less, the Adviser will not alter the
composition of the Trust's portfolio in a manner reasonably expected to reduce
the aggregate Discounted Value of Moody's Eligible Assets unless the Trust shall
have confirmed that, after giving effect to such alteration, the aggregate
Discounted Value of Moody's Eligible Assets would exceed the AMPS Basic
Maintenance Amount.

     8. Minimum Liquidity Level. (a) For so long as any shares of AMPS are rated
        -----------------------
by S&P, the Trust shall be required to have, as of each Valuation Date, Dividend
Coverage Assets having in the aggregate a Market Value not less than the
Dividend Coverage Amount.

     (b) As of each Valuation Date, as long as any shares of AMPS are rated by
S&P, the Trust shall determine (i) the Market Value of the Dividend Coverage
Assets owned by the Trust
                                       55
<PAGE>

as of that Valuation Date, (ii) the Dividend Coverage Amount on that Valuation
Date, and (iii) whether the Minimum Liquidity Level is met as of that Valuation
Date. The calculations of the Dividend Coverage Assets, the Dividend Coverage
Amount and whether the Minimum Liquidity Level is met shall be set forth in a
certificate (a "Certificate of Minimum Liquidity") dated as of the Valuation
Date. The AMPS Basic Maintenance Report and the Certificate of Minimum Liquidity
may be combined in one certificate. The Trust shall cause the Certificate of
Minimum Liquidity to be delivered to S&P not later than the close of business on
the third Business Day after the Valuation Date applicable to such Certificate
pursuant to paragraph 7(b). The Minimum Liquidity Level shall be deemed to be
met as of any date of determination if the Trust has timely delivered a
Certificate of Minimum Liquidity relating to such date which states that the
same has been met and which is not manifestly inaccurate. In the event that a
Certificate of Minimum Liquidity is not delivered to S&P when required, the
Minimum Liquidity Level shall be deemed not to have been met as of the
applicable date.

     (c) If the Minimum Liquidity Level is not met as of any Valuation Date,
then the Trust shall purchase or otherwise acquire Dividend Coverage Assets to
the extent necessary so that the Minimum Liquidity Level is met as of the fifth
Business Day following such Valuation Date. The Trust shall, by such fifth
Business Day, provide to S&P a Certificate of Minimum Liquidity setting forth
the calculations of the Dividend Coverage Assets and the Dividend Coverage
Amount and showing that the Minimum Liquidity Level is met as of such fifth
Business Day together with a report of the custodian of the Trust's assets
confirming the amount of the Trust's Dividend Coverage Assets as of such fifth
Business Day.

     9.  Certain Other Restrictions.
         --------------------------
     (a) For so long as any shares of AMPS are rated by S&P, the Trust will not
purchase or sell futures contracts, write, purchase or sell options on futures
contracts or write put options (except covered put options) or call options
(except covered call options) on portfolio securities unless it receives written
confirmation from S&P that engaging in such transactions will not impair the
ratings then assigned to the shares of AMPS by S&P, except that the Trust may
purchase or sell futures contracts based on the Bond Buyer Municipal Bond Index
(the "Municipal Index") or United States Treasury Bonds with remaining
maturities of ten years or more ("Treasury Bonds") and write, purchase or sell
put and call options on such contracts (collectively, "S&P Hedging
Transactions"), subject to the following limitations:

         (i) the Trust will not engage in any S&P Hedging Transaction based on
     the Municipal Index (other than transactions which terminate a futures
     contract or option held by the Trust by the Trust's taking an opposite
     position thereto ("Closing Transactions")), which would cause the Trust at
     the time of such transaction to own or have sold the least of (A) more than
     1,000 outstanding futures contracts based on the Municipal Index, (B)
     outstanding futures contracts based on the Municipal Index exceeding in
     number 25% of the quotient of the Market Value of the Trust's total assets
     divided by $100,000 or (C) outstanding futures contracts based on the

     total assets divided by $100,000 or (B) outstanding futures contracts based
     on Treasury Bonds exceeding in number 10% of the average number of daily
     traded futures contracts based on Treasury Bonds in the 30 days preceding
     the time of effecting such transaction as reported by The Wall Street

         (iii)  the Trust will engage in Closing Transactions to close out any
     outstanding futures contract which the Trust owns or has sold or any
     outstanding option thereon owned by the Trust in the event (A) the Trust
     does not have S&P Eligible Assets with an aggregate Discounted Value equal
     to or greater than the AMPS Basic Maintenance Amount on two consecutive
     Valuation Dates and (B) the Trust is required to pay Variation Margin on
     the second such Valuation Date;

         (iv) the Trust will engage in a Closing Transaction to close out any
     outstanding futures contract or option thereon in the month prior to the
     delivery month under the terms of such futures contract or option thereon
     unless the Trust holds the securities deliverable under such terms; and

         (v) when the Trust writes a futures contract or option thereon, it will
     either maintain an amount of cash, cash equivalents or short-term, fixed-
     income securities in a segregated account with the Trust's custodian, so
     that the amount so segregated plus the amount of Initial Margin and
     Variation Margin held in the account of or on behalf of the Trust's broker
     with respect to such futures contract or option equals the Market Value of
     the futures contract or option, or, in the event the Trust writes a futures
     contract or option

                                       58

     thereon which requires delivery of an underlying security, it shall hold
     such underlying security in its portfolio.

     For purposes of determining whether the Trust has S&P Eligible Assets with
a Discounted Value that equals or exceeds the AMPS Basic Maintenance Amount, the
Discounted Value of cash or securities held for the payment of Initial Margin or
Variation Margin shall be zero and the aggregate Discounted Value of S&P
Eligible Assets shall be reduced by an amount equal to (i) 30% of the aggregate
settlement value, as marked to market, of any outstanding futures contracts
based on the Municipal Index which are owned by the Trust plus (ii) 25% of the
aggregate settlement value, as marked to market, of any outstanding futures
contracts based on Treasury Bonds which contracts are owned by the Trust.

     (b) For so long as any shares of AMPS are rated by Moody's, the Trust will
not buy or sell futures contracts, write, purchase or sell call options on
futures contracts or purchase put options on futures contracts or write call
options (except covered call options) on portfolio securities unless it receives
written confirmation from Moody's that engaging in such transactions would not
impair the ratings then assigned to the shares of AMPS by Moody's, except that
the Trust may purchase or sell exchange-traded futures contracts based on the
Municipal Index or Treasury Bonds and purchase, write or sell exchange-traded
put options on such futures contracts and purchase, write or sell exchange-
traded call options on such futures contracts (collectively, "Moody's Hedging
Transactions"), subject to the following limitations:

         (i) the Trust will not engage in any Moody's Hedging Transaction based
     on the Municipal Index (other than Closing Transactions) which would cause
     the Trust at the time of such transaction to own or have sold (A)
     outstanding futures contracts based on the Municipal Index exceeding in
     number 10% of the average number of daily traded

                                       59
<PAGE>

     futures contracts based on the Municipal Index in the 30 days preceding the
     time of effecting such transaction as reported by The Wall Street Journal
                                                       -----------------------
     or (B) outstanding futures contracts based on the Municipal Index having a
     Market Value exceeding 50% of the Market Value of all Moody's Eligible
     Assets owned by the Trust (other than Moody's Eligible Assets already
     subject to a Moody's Hedging Transaction);

         (ii) the Trust will not engage in any Moody's Hedging Transaction based
     on Treasury Bonds (other than Closing Transactions) which would cause the
     Trust at the time of such transaction to own or have sold (A) outstanding
     futures contracts based on Treasury Bonds having an aggregate Market Value
     exceeding 20% of the aggregate Market Value of Moody's Eligible Assets
     owned by the Trust and rated Aa by Moody's (or, if not rated by Moody's but
     rated by S&P, rated AAA by S&P) or (B) outstanding futures contracts based
     on Treasury Bonds having an aggregate Market Value exceeding 40% of the
     aggregate Market Value of all Moody's Eligible Assets owned by the Trust
     (other than Moody's Eligible Assets already subject to a Moody's Hedging
     Transaction) and rated Baa or A by Moody's (or, if not rated by Moody's but
     rated by S&P, rated A or AA by S&P) (for purposes of the foregoing clauses
     (i) and (ii), the Trust shall be deemed to own the number of futures
     contracts that underlie any outstanding options written by the Trust);

         (iii) the Trust will engage in Closing Transactions to close out any
outstanding futures contract based on the Municipal Index if the amount of open
interest in the Municipal Index as reported by The Wall Street Journal is less
                                               -----------------------
than 5,000;

         (iv) the Trust will engage in a Closing Transaction to close out any
     outstanding futures contract by no later than the fifth Business Day of the
     month in which such

                                       60
<PAGE>

     contract expires and will engage in a Closing Transaction to close out any
     outstanding option on a futures contract by no later than the first
     Business Day of the month in which such option expires;

         (v) the Trust will engage in Moody's Hedging Transactions only with
     respect to futures contracts or options thereon having the next settlement
     date or the settlement date immediately thereafter;

         (vi) in the event the Trust writes a futures contract or option thereon
     which requires delivery of an underlying security, it shall hold such
     underlying security in its portfolio;

         (vii) the Trust will not engage in options and futures transactions for
     leveraging or speculative purposes and will not write any call options or
     sell any futures contracts for the purpose of hedging the anticipated
     purchase of an asset prior to completion of such purchase; and

         (viii) the Trust will not enter into an option or futures transaction
     unless, after giving effect thereto, the Trust would continue to have
     Moody's Eligible Assets with an aggregate Discounted Value equal to or
     greater than the AMPS Basic Maintenance Amount.

     For purposes of determining whether the Trust has Moody's Eligible Assets
with an aggregate Discounted Value that equals or exceeds the AMPS Basic
Maintenance Amount, the Discounted Value of Moody's Eligible Assets which the
Trust is obligated to deliver or receive pursuant to an outstanding futures
contract or option shall be as follows:  (i) assets subject to call options
written by the Trust which are either exchange-traded and "readily reversible"
or which expire within 49 days after the date as of which such valuation is made
shall be valued at the

                                       61
<PAGE>

lesser of (a) Discounted Value and (b) the exercise price of the call option
written by the Trust; (ii) assets subject to call options written by the Trust
not meeting the requirements of clause (i) of this sentence shall have no value;
(iii) assets subject to put options written by the Trust shall be valued at the
lesser of (A) the exercise price and (B) the Discounted Value of the subject
security; (iv) futures contracts shall be valued at the lesser of (A) settlement
price and (B) the Discounted Value of the subject security, provided that, if a
contract matures within 49 days after the date as of which such valuation is
made, where the Trust is the seller the contract may be valued at the settlement
price and where the Trust is the buyer the contract may be valued at the
Discounted Value of the subject securities and (v) where delivery may be made to
the Trust with any security of a class of securities, the Trust shall assume
that it will take delivery of the security with the lowest Discounted Value.

     For purposes of determining whether the Trust has Moody's Eligible Assets
with an aggregate Discounted Value that equals or exceeds the AMPS Basic
Maintenance Amount, the following amounts shall be subtracted from the aggregate
Discounted Value of the Moody's Eligible Assets held by the Trust: (i) 10% of
the exercise price of a written call option; (ii) the exercise price of any
written put option; (iii) where the Trust is the seller under a futures
contract, 10% of the settlement price of the futures contract; (iv) where the
Trust is the purchaser under a futures contract, the settlement price of assets
purchased under such futures contract; (v) the settlement price of the
underlying futures contract if the Trust writes put options on a futures
contract; and (vi) 105% of the Market Value of the underlying futures contracts
if the Trust writes call options on a futures contract and does not own the
underlying contract.

     (c) For so long as any shares of AMPS are rated by Moody's, the Trust will
not enter into any contract to purchase securities for a fixed price at a future
date beyond customary

                                       62
<PAGE>

settlement time (other than such contracts that constitute Moody's Hedging
Transactions that are permitted under paragraph 9(b) of these Certificate of
Designation), except that the Trust may enter into such contracts to purchase
newly-issued securities on the date such securities are issued ("Forward
Commitments"), subject to the following limitations:

         (i) the Trust will maintain in a segregated account with its custodian
     cash, cash equivalents or short-term, fixed-income securities rated P-1,
     MIG-1 or VMIG-1 by Moody's and maturing prior to the date of the Forward
     Commitment with a Market Value that equals or exceeds the amount of the
     Trust's obligations under any Forward Commitments to which it is from time
     to time a party or long-term fixed income securities with a Discounted
     Value that equals or exceeds the amount of the Trust's obligations under
     any Forward Commitment to which it is from time to time a party; and

        (ii) the Trust will not enter into a Forward Commitment unless, after
     giving effect thereto the Trust would continue to have Moody's Eligible
     Assets with an aggregate Discounted Value equal to or greater than the AMPS
     Basic Maintenance Amount.

     For purposes of determining whether the Trust has Moody's Eligible Assets
with an aggregate Discounted Value that equals or exceeds the AMPS Basic
Maintenance Amount, the Discounted Value of all Forward Commitments to which the
Trust is a party and of all securities deliverable to the Trust pursuant to such
Forward Commitments shall be zero.

     (d) For so long as shares of AMPS are rated by S&P or Moody's, the Trust
will not, unless it has received written confirmation from S&P and/or Moody's,
as the case may be, that such action would not impair the ratings then assigned
to shares of AMPS by S&P and/or Moody's, as the case may be, (i) borrow money
except for the purpose of clearing transactions in

                                       63
<PAGE>

portfolio securities (which borrowings shall under any circumstances be limited
to the lesser of $10 million and an amount equal to 5% of the Market Value of
the Trust's assets at the time of such borrowings and which borrowings shall be
repaid within 60 days and not be extended or renewed), (ii) engage in short
sales of securities, (iii) lend any securities, (iv) issue any class or series
of stock ranking prior to or on a parity with the AMPS with respect to the
payment of dividends or the distribution of assets upon dissolution, liquidation
or winding up of the Trust, (v) reissue any AMPS previously purchased or
redeemed by the Trust, (vi) merge or consolidate into or with any other entity,
(vii) change the Pricing Service or (viii) engage in reverse repurchase
agreements.

     10. Notice. All notices or communications, unless otherwise specified in

Deadline on each Auction Date all orders obtained by such Broker-Dealer and
specifying with respect to each Order:

         (A)  the name of the Bidder placing such Order;

     subject of such Order;

         (C)  to the extent that such Bidder is an Existing Holder:

              (1) the number of Outstanding shares, if any, of AMPS subject to
         any Hold Order placed by such Existing Holder;

              (2) the number of Outstanding shares, if any, of AMPS subject to
         any Bid placed by such Existing Holder and the rate per annum specified

<PAGE>

              (3) the number of Outstanding shares, if any, of AMPS subject to
         any Sell Order placed by such Existing Holder; and

         (D) to the extent such Bidder is a Potential Holder, the rate per annum
     specified in such Potential Holder's Bid.

         (ii) If any rate per annum specified in any Bid contains more than
three figures to the right of the decimal point, the Auction Agent shall round
such rate up to the next highest one-thousandth (.001) of 1%.

         (iii) If an Order or Orders covering all of the Outstanding shares of
AMPS held by an Existing Holder are not submitted to the Auction Agent prior to
the Submission Deadline, the Auction Agent shall deem a Hold Order (in the case
of an Auction relating to a Dividend Period which is not a Special Dividend
Period) and a Sell Order (in the case of an Auction relating to a Special
Dividend Period) to have been submitted on behalf of such Existing Holder
covering the number of Outstanding shares of AMPS held by such Existing Holder
and not subject to Orders submitted to the Auction Agent.

         (iv) If one or more Orders on behalf of an Existing Holder covering in
the aggregate more than the number of Outstanding shares of AMPS held by such
Existing Holder are submitted to the Auction Agent, such Order shall be
considered valid as follows and in the following order of priority:

         (A) any Hold Order submitted on behalf of such Existing Holder shall be
     considered valid up to and including the number of Outstanding shares of
     AMPS held by such Existing Holder; provided that if more than one Hold
     Order is submitted on behalf of such Existing Holder and the number of
     shares of AMPS subject to such Hold Orders exceeds the number of
     Outstanding shares of AMPS held by such Existing Holder, the

                                       70
<PAGE>

     number of shares of AMPS subject to each of such Hold Orders shall be
     reduced pro rata so that such Hold Orders, in the aggregate, will cover
     exactly the number of Outstanding shares of AMPS held by such Existing
     Holder;

         (B) any Bids submitted on behalf of such Existing Holder shall be
     considered valid, in the ascending order of their respective rates per
     annum if more than one Bid is submitted on behalf of such Existing Holder,
     up to and including the excess of the number of Outstanding shares of AMPS
     held by such Existing Holder over the number of shares of AMPS subject to
     any Hold Order referred to in paragraph 11(c)(iv)(A) above (and if more
     than one Bid submitted on behalf of such Existing Holder specifies the same
     rate per annum and together they cover more than the remaining number of
     shares that can be the subject of valid Bids after application of paragraph
     11(c)(iv)(A) above and of the foregoing portion of this paragraph
     11(c)(iv)(B) to any Bid or Bids specifying a lower rate or rates per annum,
     the number of shares subject to each of such Bids shall be reduced pro rata
     so that such Bids, in the aggregate, cover exactly such remaining number of
     shares); and the number of shares, if any, subject to Bids not valid under
     this paragraph 11(c)(iv)(B) shall be treated as the subject of a Bid by a
     Potential Holder; and

         (C) any Sell Order shall be considered valid up to and including the
     excess of the number of Outstanding shares of AMPS held by such Existing
     Holder over the number of shares of AMPS subject to Hold orders referred to
     in paragraph 11(c)(iv)(A) and Bids referred to in paragraph 11(c)(iv)(B);
     provided that if more than one Sell Order is submitted on behalf of any
     Existing Holder and the number of shares of AMPS subject to such Sell
     Orders is greater than such excess, the number of shares of AMPS subject to

                                       71
<PAGE>

     each of such Sell Orders shall be reduced pro rata so that such Sell
     Orders, in the aggregate, cover exactly the number of shares of AMPS equal
     to such excess.

         (v) If more than one Bid is submitted on behalf of any Potential
Holder, each Bid submitted shall be a separate Bid with the rate per annum and
number of shares of AMPS therein specified.

     (d) Determination of Sufficient Clearing Bids, Winning Bid Rate and
         ---------------------------------------------------------------
Applicable Rate.
- ---------------

         (i) Not earlier than the Submission Deadline on each Auction Date, the
Auction Agent shall assemble all Orders submitted or deemed submitted to it by
the Broker-Dealers (each such Order as submitted or deemed submitted by a
Broker-Dealer being hereinafter referred to individually as a "Submitted Hold
Order", a "Submitted Bid" or a "Submitted Sell Order", as the case may be, or as
a "Submitted Order") and shall determine:

         (A) the excess of the total number of Outstanding shares of AMPS over
     the number of Outstanding shares of AMPS that are the subject of Submitted
     Hold Orders (such excess being hereinafter referred to as the "Available
     AMPS");

         (B) from the Submitted Orders whether the number of Outstanding shares
     of AMPS that are the subject of Submitted Bids by Potential Holders
     specifying one or more rates per annum equal to or lower than the Maximum
     Applicable Rate exceeds or is equal to the sum of:

              (1) the number of Outstanding shares of AMPS that are the subject
         of Submitted Bids by Existing Holders specifying one or more rates per
         annum higher than the Maximum Applicable Rate, and

                                       72
<PAGE>

              (2) the number of Outstanding shares of AMPS that are subject to
         Submitted Sell Orders (if such excess or such equality exists (other
         than because the number of Outstanding shares of AMPS in clauses (1)
         and (2) above are each zero because all of the Outstanding shares of
         AMPS are the subject of Submitted Hold Orders), such Submitted Bids by
         Potential Holders being hereinafter referred to collectively as
         "Sufficient Clearing Bids"); and

         (C) if Sufficient Clearing Bids exist, the lowest rate per annum
     specified in the Submitted Bids (the "Winning Bid Rate") that if:

              (1) each Submitted Bid from Existing Holders specifying the
         Winning Bid Rate and all other Submitted Bids from Existing Holders
         specifying lower rates per annum were rejected, thus entitling such
         Existing Holders to continue to hold the shares of AMPS that are the
         subject of such Submitted Bids, and

              (2) each Submitted Bid from Potential Holders specifying the
         Winning Bid Rate and all other Submitted Bids from Potential Holders
         specifying lower rates per annum were accepted, thus entitling the
         Potential Holders to purchase the shares of AMPS that are the subject
         of such Submitted Bids,

would result in the number of shares subject to all Submitted Bids specifying
the Winning Bid Rate or a lower rate per annum being at least equal to the
Available AMPS.

         (ii) Promptly after the Auction Agent has made the determinations
pursuant to paragraph 11(d)(i), the Auction Agent shall advise the Trust of the
Maximum Applicable Rate and, based on such determinations, the Applicable Rate
for the next succeeding Dividend Period as follows:

                                       73
<PAGE>

         (A) if Sufficient Clearing Bids exist, that the Applicable Rate for the
     next succeeding Dividend Period shall be equal to the Winning Bid Rate;

         (B) if Sufficient Clearing Bids do not exist (other than because all of
     the Outstanding shares of AMPS are the subject of Submitted Hold Orders),
     that the Applicable Rate for the next succeeding Dividend Period shall be
     equal to the Maximum Applicable Rate; or

         (C) if all of the Outstanding shares of AMPS are the subject of
     Submitted Hold orders, that the Dividend Period next succeeding the Auction
     shall automatically be the same length as the immediately preceding
     Dividend Period and the Applicable Rate for the next succeeding Dividend
     Period shall be equal to 59% of the Reference Rate (or 90% of such rate if
     the Trust has provided notification to the Auction Agent prior to the
     Auction establishing the Applicable Rate for any dividend pursuant to
     paragraph 2(f) hereof that net capital gains or other taxable income will
     be included in such dividend on shares of AMPS) on the date of the Auction.

     (e) Acceptance and Rejection of Submitted Bids and Submitted Sell Orders
and Allocation of Shares. Based on the determinations made pursuant to paragraph
11(d)(i), the Submitted Bids and Submitted Sell Orders shall be accepted or
rejected and the Auction Agent shall take such other action as set forth below:

         (i) If Sufficient Clearing Bids have been made, subject to the
provisions of paragraph 11(e)(iii) and paragraph 11(e)(iv), Submitted Bids and
Submitted Sell Orders shall be accepted or rejected in the following order of
priority and all other Submitted Bids shall be rejected:

                                       74
<PAGE>

         (A) the Submitted Sell Orders of Existing Holders shall be accepted and
     the Submitted Bid of each of the Existing Holders specifying any rate per
     annum that is higher than the Winning Bid Rate shall be accepted, thus
     requiring each such Existing Holder to sell the Outstanding shares of AMPS
     that are the subject of such Submitted Sell Order or Submitted Bid;

         (B) the Submitted Bid of each of the Existing Holders specifying any
     rate per annum that is lower than the Winning Bid Rate shall be rejected,
     thus entitling each such Existing Holder to continue to hold the
     Outstanding shares of AMPS that are the subject of such Submitted Bid;

         (C) the Submitted Bid of each of the Potential Holders specifying any
     rate per annum that is lower than the Winning Bid Rate shall be accepted;

         (D) the Submitted Bid of each of the Existing Holders specifying a rate
     per annum that is equal to the Winning Bid Rate shall be rejected, thus
     entitling each such Existing Holder to continue to hold the Outstanding
     shares of AMPS that are the subject of such Submitted Bid, unless the
     number of Outstanding shares of AMPS subject to all such Submitted Bids
     shall be greater than the number of Outstanding shares of AMPS ("Remaining
     Shares") equal to the excess of the Available AMPS over the number of
     Outstanding shares of AMPS subject to Submitted Bids described in paragraph
     11(e)(i)(B) and paragraph 11(e)(i)(C), in which event the Submitted Bids of
     each such Existing Holder shall be accepted, and each such Existing Holder
     shall be required to sell Outstanding shares of AMPS, but only in an amount
     equal to the difference between (1) the number of Outstanding shares of
     AMPS then held by such Existing Holder subject to such Submitted Bid and
     (2) the number of shares of AMPS obtained by multiplying (x)

                                       75
<PAGE>

     the number of Remaining Shares by (y) a fraction the numerator of which
     shall be the number of Outstanding shares of AMPS held by such Existing
     Holder subject to such Submitted Bid and the denominator of which shall be
     the sum of the numbers of Outstanding shares of AMPS subject to such
     Submitted Bids made by all such Existing Holders that specified a rate per
     annum, equal to the Winning Bid Rate; and

         (E) the Submitted Bid of each of the Potential Holders specifying a
     rate per annum that is equal to the Winning Bid Rate shall be accepted but
     only in an amount equal to the number of Outstanding shares of AMPS
     obtained by multiplying (x) the difference between the Available AMPS and
     the number of Outstanding shares of AMPS subject to Submitted Bids
     described in paragraph 11(e)(i)(B), paragraph 11(e)(i)(C) and paragraph
     11(e)(i)(D) by (y) a fraction the numerator of which shall be the number of
     Outstanding shares of AMPS subject to such Submitted Bid and the
     denominator of which shall be the sum of the number of Outstanding shares
     of AMPS subject to such Submitted Bids made by all such Potential Holders
     that specified rates per annum equal to the Winning Bid Rate.

         (ii) If Sufficient Clearing Bids have not been made (other than because
all of the Outstanding shares of AMPS are subject to Submitted Hold Orders),
subject to the provisions of paragraph 11(e)(iii), Submitted Orders shall be
accepted or rejected as follows in the following order of priority and all other
Submitted Bids shall be rejected:

         (A) the Submitted Bid of each Existing Holder specifying any rate per
     annum that is equal to or lower than the Maximum Applicable Rate shall be
     rejected, thus entitling such Existing Holder to continue to hold the
     Outstanding shares of AMPS that are the subject of such Submitted Bid;

                                       76
<PAGE>

         (B) the Submitted Bid of each Potential Holder specifying any rate per
     annum that is equal to or lower than the Maximum Applicable Rate shall be
     accepted, thus requiring such Potential Holder to purchase the Outstanding
     shares of AMPS that are the subject of such Submitted Bid; and

         (C) the Submitted Bids of each Existing Holder specifying any rate per
     annum that is higher than the Maximum Applicable Rate shall be accepted and
     the Submitted Sell Orders of each Existing Holder shall be accepted, in
     both cases only in an amount equal to the difference between (1) the number
     of Outstanding shares of AMPS then held by such Existing Holder subject to
     such Submitted Bid or Submitted Sell Order and (2) the number of shares of
     AMPS obtained by multiplying (x) the difference between the Available AMPS
     and the aggregate number of Outstanding shares of AMPS subject to Submitted
     Bids described in paragraph 11(e)(ii)(A) and paragraph 11(e)(ii)(B) by (y)
     a fraction the numerator of which shall be the number of Outstanding shares
     of AMPS held by such Existing Holder subject to such Submitted Bid or
     Submitted Sell Order and the denominator of which shall be the number of
     Outstanding shares of AMPS subject to all such Submitted Bids and Submitted
     Sell Orders.

         (iii) If, as a result of the procedures described in paragraph 11(e)(i)
or paragraph 11(e)(ii), any Existing Holder would be entitled or required to
sell, or any Potential Holder would be entitled or required to purchase, a
fraction of a share of AMPS on any Auction Date, the Auction Agent shall, in
such manner as in its sole discretion it shall determine, round up or down the
number of shares of AMPS to be purchased or sold by any Existing Holder or
Potential Holder on such Auction Date so that each Outstanding share of AMPS
purchased or

                                       77
<PAGE>

sold by each Existing Holder or Potential Holder on such Auction Date shall be a
whole share of AMPS.

         (iv) If, as a result of the procedures described in paragraph 11(e)(i),
any Potential Holder would be entitled or required to purchase less than a whole
share of AMPS on any Auction Date, the Auction Agent shall, in such manner as in
its sole discretion it shall determine, allocate shares of AMPS for purchase
among Potential Holders so that only whole shares of AMPS are purchased on such
Auction Date by any Potential Holder, even if such allocation results in one or
more of such Potential Holders not purchasing any shares of AMPS on such Auction
Date.

         (v) Based on the results of each Auction, the Auction Agent shall
determine, with respect to each Broker-Dealer that submitted Bids or Sell Orders
on behalf of Existing Holders or Potential Holders, the aggregate number of
Outstanding shares of AMPS to be purchased and the aggregate number of the
Outstanding shares of AMPS to be sold by such Potential Holders and Existing
Holders and, to the extent that such aggregate number of Outstanding shares to
be purchased and such aggregate number of Outstanding shares to be sold differ,
the Auction Agent shall determine to which other Broker-Dealer or Broker-Dealers
acting for one or more purchasers such Broker-Dealer shall deliver, or from
which other Broker-Dealer or Broker-Dealers acting for one or more sellers such
Broker-Dealer shall receive, as the case may be, Outstanding shares of AMPS.

         (f) Miscellaneous. The Board of Trustees may interpret the provisions
             -------------
of this paragraph 11 to resolve any inconsistency or ambiguity, remedy any
formal defect or make any other change or modification that does not
substantially adversely affect the rights of Existing Holders of AMPS. An
Existing Holder (A) may sell, transfer or otherwise dispose of shares of

                                       78
<PAGE>

AMPS only pursuant to a Bid or Sell Order in accordance with the procedures
described in this paragraph 11 or to or through a Broker-Dealer or to a Person
that has delivered a signed copy of a Purchaser's Letter to the Auction Agent,
provided that in the case of all transfers other than pursuant to Auctions such
Existing Holder, its Broker-Dealer or its Agent Member advises the Auction Agent
of such transfer and (B) except as otherwise required by law, shall have the
ownership of the shares of AMPS held by it maintained in book entry form by the
Securities Depository in the account of its Agent Member, which in turn will
maintain records of such Existing Holder's beneficial ownership. Neither the
Trust nor any affiliate shall submit an Order in any Auction. Any Existing
Holder that is an Affiliate shall not sell, transfer or otherwise dispose of
shares of AMPS to any Person other than the Trust. All of the Outstanding shares
of AMPS shall be represented by a single certificate registered in the name of
the nominee of the Securities Depository unless otherwise required by law or
unless there is no Securities Depository. If there is no Securities Depository,
at the Trust's option and upon its receipt of such documents as it deems
appropriate, any shares of AMPS may be registered in the Stock Register in the
name of the Existing Holder thereof and such Existing Holder thereupon will be
entitled to receive certificates therefor and required to deliver certificates
therefor upon transfer or exchange thereof.

     12. Securities Depository; Share Certificates. (a) If there is a Securities
         -----------------------------------------
Depository, one certificate for all of the shares of AMPS shall be issued to the
Securities Depository and registered in the name of the Securities Depository or
its nominee. Additional certificates may be issued as necessary to represent
shares of AMPS. All such certificates shall bear a legend to the effect that
such certificates are issued subject to the provisions restricting the transfer
of shares of AMPS of a series contained in this Certificate of Designation and
each

                                       79
<PAGE>

Purchaser's Letter. Unless the Trust shall have elected, during a Non-Payment
Period, to waive this requirement, the Trust will also issue stop-transfer
instructions to the Auction Agent for the shares of AMPS. Except as provided in
paragraph (b) below, the Securities Depository or its nominee will be the
Holder, and no Existing Holder shall receive certificates representing its
ownership interest in such shares.

     (b) If the Applicable Rate applicable to all shares of AMPS shall be the
Non-Payment Period Rate or there is no Securities Depository, the Trust may at
its option issue one or more new certificates with respect to such shares
(without the legend referred to in paragraph 12(a)) registered in the names of
the Existing Holders or their nominees and rescind the stop-transfer
instructions referred to in paragraph 12(a) with respect to such shares.

     13.  Personal Liability.  The Declaration of Trust establishing MuniYield
          ------------------
Pennsylvania Fund, dated August 26, 1992, a copy of which, together with all
amendments thereto, is on file in the office of the Secretary of the
Commonwealth of Massachusetts, provides that the name "MuniYield Pennsylvania
Fund" refers to the Trustees under the Declaration collectively as Trustees, but
not as individuals or personally; and no Trustee, shareholder, officer, employee
or agent of the Trust shall be held to any personal liability, nor shall resort
be had to their private property for the satisfaction of any obligation or claim
or otherwise in connection with the affairs of the Trust, but the "Trust
Property" only shall be liable.

Section 1.1   Chairman. The Chairman, if any, shall act as chairman at all
              --------
meetings of the Shareholders; in his absence, the President shall act as
chairman; and in the absence of the Chairman and President, the Trustee or
Trustees present at each meeting may elect a temporary chairman for the meeting,
who may be one of themselves.

Section 1.2   Proxies; Voting. Shareholders may vote either in person or by duly
              ---------------
executed proxy and each full share represented at the meeting shall have one
vote, all as provided in Article IX of the Declaration. No proxy shall be valid
after eleven (11) months from the date of its execution, unless a longer period
is expressly stated in such proxy.

Section 1.3   Closing of Transfer Books and Fixing Record Dates. For the purpose
              -------------------------------------------------
of determining the Shareholders who are entitled to notice of or to vote or act
at any meeting, including any adjournment thereof, or who are entitled to
participate in from time to time close the transfer books or fix a record date
in the manner provided in Section 9.4 of the Declaration. If the Trustees do not

books, then the date of mailing notice of the meeting or the date upon which the
dividend resolution is adopted, as the case may be, shall be the record date.

Section 1.4   Inspectors of Election. In advance of any meeting of Shareholders,
              ----------------------

challenges and questions in any way arising in connection with the right to
vote, shall count and tabulate all votes or consents, determine the results, and
do such other acts as may be proper to conduct the election or vote with
fairness to all Shareholders. If there are three Inspectors of Election, the
decision, act or certificate of a majority is effective in all respects as the
decision, act or certificate of all. On request of the Chairman, if any, of the
meeting, or of any Shareholder or his proxy, the Inspectors of Election shall
make a report in writing of any challenge or question or matter determined by
them and shall execute a certificate of any facts found by them.

Trust, as of the record date of the meeting or the date of closing of transfer
books, as the case may be. Such list of Shareholders shall contain the name of
each Shareholder in alphabetical order and the address of and number of Shares
owned by such Shareholder.  Shareholders shall have such other rights and
procedures of inspection of the books and records of the Trust as are granted to
shareholders of a Massachusetts business corporation.

                                  ARTICLE III
                                  -----------

                     Compensation of the Investment Adviser
                     --------------------------------------

(a)  Investment Advisory Fee.  For the services rendered, the facilities
     -----------------------
     furnished and expenses assumed by the Investment Adviser, the Fund shall
     pay to the Investment Adviser at the end of each calendar month a fee based
     upon the average weekly value of the net assets of the Fund at the annual
     rate of 0.50 of 1.0% (0.50%) of the average weekly net assets of the Fund
     (i.e., the average weekly value of the total assets of the Fund, minus the
     -----
     sun of accrued liabilities of the Fund and accumulated dividends on
     outstanding preferred shares), commencing on the day following
     effectiveness hereof. For purposes of this calculation, average weekly net
     assets is 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. It is understood that the liquidation preference of any
     outstanding preferred shares (other

                                       5
<PAGE>

     than accumulated dividends) is not considered a liability in determining
     the Fund's average weekly net assets. If this Agreement becomes effective
     subsequent to the first day of a month or shall terminate before the last
     day of a month, compensation for that part of the month this Agreement is
     in effect shall be prorated in a manner consistent with the calculation of
     the fee as set forth above. Subject to the provisions of subsection (b)
     hereof, payment of the Investment Adviser's compensation for the preceding
     month shall be made as promptly as possible after completion of the
     computations contemplated by subsection (b) hereof. During any period when
     the determination of net asset value is suspended by the Board of Trustees,
     the average net asset value of a share for the last week prior to such
     suspension shall for this purpose be deemed to be the net asset value at
     the close of each succeeding week until it is again determined.

(b)  Expense Limitations.  In the event the operating expenses of the Fund,
     -------------------
     including amounts payable to the Investment Adviser pursuant to subsection
     (a) hereof, for any fiscal year ending on a date on which this Agreement is
     in effect exceed the expense limitations applicable to the Fund imposed by
     applicable state securities laws or regulations thereunder, as such
     limitations may be raised or lowered from time to time, the Investment
     Adviser shall reduce its management and investment advisory fee by the
     extent of such excess and, if required pursuant to any such laws or
     regulations, will reimburse the Fund in the amount of such excess;
     provided, however, to the extent permitted by law, there shall be excluded
     from such expenses the amount of any interest, taxes, brokerage fees and
     commissions and extraordinary expenses (including but not limited to legal
     claims and liabilities and litigation costs and any indemnification related
     thereto) paid or payable by the Fund. Whenever the expenses of the Fund
     exceed a pro rata portion of the applicable annual expense limitations, the
     estimated amount of reimbursement under such limitations shall be
     applicable as an offset against the monthly payment of the fee due

                                       6
<PAGE>

     to the Investment Adviser. Should two or more such expenses limitations be
     applicable as at the end of the last business day of the month, that
     expense limitation which results in the largest reduction in the Investment
     Adviser's fee shall be applicable.

                                  ARTICLE IV

mistake of law or for any loss arising out of any investment or for any act or

reckless disregard of its obligations and duties hereunder. As used in this
Article IV, the term "Investment Adviser" shall include any affiliates of the

Adviser and its affiliates are or may become similarly interested in the Fund,

                             FUND ASSET MANAGEMENT

As of January 1, 1994 Fund Asset Management was reorganized as a limited
partnership, formally known as Fund Asset Management, L.P. ("FAM").  The general
partner of FAM is Princeton Services, Inc. and the limited partners are Fund
Asset Management, Inc. and Merrill Lynch & Co. Inc.  Pursuant to Rule 202(a)(l)-
l under the Investment Advisers Act of 1940 and Rule 2a-6 under the Investment
Company Act of 1940 such reorganization did not constitute an assignment of this
investment advisory agreement since it did not involve a change of control or
management of the investment adviser. Pursuant to the requirements of Section
205 of the Investment Advisers Act of 1940, however, Fund Asset Management
hereby supplements this investment advisory agreement by undertaking to advise
you of any change in the membership of the partnership within a reasonable time
after any such change occurs.

the purchase by the Underwriter of 5,321,088 common shares of beneficial
interest, par value $.10 per share, of the Fund (the "Common Shares") and, with
respect to the grant by the Fund to the Underwriter of the option described in
Section 2 hereof to purchase all or any part of 212,844 additional Common Shares
to cover overallotments. The aforesaid 5,321,088 shares (the "Initial Shares"),
together with all or any part of the 212,844 additional Common Shares subject to
the option described in Section 2 hereof (the "Option Shares"), are
collectively hereinafter called the "Shares".

     Prior to the purchase and public offering of the Shares by the Underwriter,
the Fund and the Underwriter shall enter into an agreement substantially in the
form of Exhibit A hereto (the "Pricing Agreement"). The Pricing Agreement may
take the form of an exchange of any standard form of written telecommunication
between the Fund and the Underwriter and shall specify such applicable
information as is indicated in Exhibit A hereto. The offering of the Shares will
be governed by this Agreement, as supplemented by the Pricing Agreement. From
and after the date of the execution and delivery of the Pricing Agreement, this
Agreement shall be deemed to incorporate the Pricing Agreement.

     The Fund has filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form N-2 (No. 33-51410) and a related
preliminary prospectus for the registration of the Shares under the Securities
Act of 1933, as amended (the 111933 Act"), and a notification on Form N-BA of
registration of the Fund as an investment company under the Investment Company
Act of 1940, as amended (the "1940 Act"), and the rules and regulations of
<PAGE>

the Commission under the 1940 Act (together with the rules and regulations under
the 1933 Act, the "Rules and Regulations") and has filed such amendments to such
registration statement on Form N2, if any, and such amended preliminary
prospectuses as may have been required to the date hereof. The Fund will prepare
and file such additional amendments thereto and such amended prospectuses as may
hereafter be required. Such registration statement (as amended, if applicable)
and the prospectus constituting a part thereof (including in each case the
information, if any, deemed to be part thereof pursuant to Rule 430A(b) of the
Rules and Regulations), as from time to time amended or supplemented pursuant to
the 1933 Act, are hereinafter referred to as the "Registration Statement" and
the "Prospectus", respectively, except that if any revised prospectus shall be
provided to the Underwriter by the Fund for use in connection with the offering
of the Shares which differs from the Prospectus on file at the Commission at the
time the Registration Statement becomes effective (whether such revised
prospectus is required to be filed by the Fund pursuant to Rule 497 (b) or Rule
497 (h) of the Rules and Regulations) , the term "Prospectus" shall refer to
each such revised prospectus from and after the time it is first provided to the
Underwriter for such use.

     and delivered by the Adviser and constitutes a valid and binding obligation
     of the Adviser, enforceable in accordance with its terms, subject, as to
     enforcement, to bankruptcy, insolvency, reorganization or other laws
     relating to or affecting creditors' rights and to general equity
     principles; and neither the execution and delivery of this Agreement, or
     the Advisory Agreement nor the performance by the Adviser of its
     obligations hereunder or thereunder will conflict with, or result in a
     breach of any of the terms and provisions of, or constitute, with or
     without the giving of notice or lapse of time or both, a default under, any
     agreement or instrument to which the Adviser is a party or by which it is

     jurisdiction, court, federal or state regulatory body, administrative

     having jurisdiction over the Adviser or its respective properties or
     operations.

        (iv) The Adviser has the financial resources available to it necessary
     for the performance of its services and obligations as contemplated in the
     Prospectus.

        (v)  Any advertisement approved by the Adviser for use in the public

     (an "Omitting Prospectus") complies with the requirements of such Rule 482.

     (c)  Any certificate signed by any officer of the Fund or the Adviser and
delivered to the Underwriter shall be deemed a representation and warranty by
the Fund or the Adviser, as the case may be, to the Underwriter, as to the
matters covered thereby.

     SECTION 2.  Sale and Delivery to the Underwriter; Closing. On the basis of
the representations and warranties herein contained and subject to the terms and
conditions herein set forth, the Fund agrees to sell the Initial Shares to the
Underwriter, and the Underwriter agrees to purchase the Initial Shares from the
Fund, at the price per share set forth in the Pricing Agreement.

     (a)  If the Fund has elected not to rely upon Rule 430A under the Rules and
Regulations, the initial public offering prices and the purchase price per share
to be paid by the Underwriter for the Shares has been determined and set forth
in the Pricing Agreement, dated the date hereof, and an amendment to the
Registration Statement and the Prospectus will be filed before the Registration
Statement becomes effective.

     (b)  If the Fund has elected to rely upon Rule 430A under the Rules and
Regulations, the purchase price per share to be paid by the Underwriter for the
Shares shall be an amount equal to the applicable initial public offering price,
less an amount per share to be determined by agreement between the Underwriter
and the Fund. The applicable initial public offering price per share shall be a
fixed price based upon the number of Shares purchased in a single transaction to
be determined by agreement between the Underwriter and the Fund. The initial
public offering prices and the purchase price, when so determined, shall be set
forth in the Pricing Agreement. In the event that such prices have not been
agreed upon and the Pricing Agreement has not been executed and delivered by all
parties thereto by the close of business on the fourth business day

                                       5

following the date of this Agreement, this Agreement shall terminate forthwith,
without liability of any party to any other party, except as provided in Section
4, unless otherwise agreed to by the Fund, the Adviser and the Underwriter.

     In addition, on the basis of the representations and warranties herein
contained and subject to the terms and conditions herein set forth, the Fund
hereby grants an option to the Underwriter to purchase all or any part of the
Option Shares at the price per share set forth above, less an amount equal to
any dividend paid by the Fund and payable on any Initial Shares and not payable
on such option Shares. The option hereby granted will expire 45 days after the
date hereof (or, if the Fund has elected to rely upon Rule 430A under the Rules
and Regulations, 45 days after the execution of the Pricing Agreement) and may
be exercised only for the purpose of covering over-allotments which may be made
in connection with the offering and distribution of the Initial Shares upon
notice by the Underwriter to the Fund setting forth the number of Option Shares
as to which the Underwriter is then exercising the option and the time, date and
place of payment and delivery for such Option Shares. Any such time and date of
delivery (a "Date of Delivery") shall be determined by the Underwriter but shall
not be later than seven full business days after the exercise of said option,
nor in any event prior to Closing Time, as hereinafter defined, unless otherwise
agreed upon by the Underwriter and the Fund.

     Payment of the purchase price for, and delivery of certificates for, the
Initial Shares shall be made at the office of Brown & Wood, One World Trade
Center, New York, New York 10048-0557, or at such other place as shall be agreed
upon by the Underwriter and the Fund, at 10:00 A.M. on the fifth business day
(unless postponed in accordance with the provisions of Section 10) following the
date the Registration Statement becomes effective (or, if the Fund has elected
to rely upon Rule 430A under the Rules and Regulations, the f ifth business day
after execution of the Pricing Agreement), or such other time not later than ten
business days after such date as shall be agreed upon by the Underwriter and the
Fund (such time and date of payment and delivery being herein called "Closing
Time"). In addition, in the event that any or all of the option Shares are
purchased by the Underwriter, payment of the purchase price for, and delivery of
certificates for, such Option Shares shall be made at the above-mentioned office
of Brown & Wood, or at such other place as shall be mutually agreed upon by the
Fund and the Underwriter, on each Date of Delivery as specified in the notice
from the Underwriter to the Fund. Payment shall be made to the Fund by check or
checks drawn in New York Clearing House or similar next day funds and payable to
the order of the Fund, against delivery to the Underwriter of certificates for
the Shares to be purchased by it. Certificates for the Initial Shares and Option
Shares shall be in such denominations and registered in such names as the
Underwriter may request in writing at least two business days before Closing
Time or the Date of Delivery, as the case may be. The certificates for the
Initial Shares and the Option Shares will be made available by the Fund for
examination and packaging by the Underwriter not later than 10:00 A.M. on the
last business day prior to Closing Time or the Date of Delivery, as the case may
be.

     SECTION 3.  Covenants of the Fund. The Fund covenants with the Underwriter
as follows:

     (a)  The Fund will use its best efforts to cause the Registration Statement
to become effective under the 1933 Act, and will advise the Underwriter promptly
as to the time at which

                                       6
<PAGE>

the Registration Statement and any amendments thereto (including any post-
effective amendment) becomes so effective and, if required, to cause the
issuance of any orders exempting the Fund from any provisions of the 1940 Act
and will advise the Underwriter promptly as to the time at which any such orders
are granted.

     (b)  The Fund will notify the Underwriter immediately, and confirm the
notice in writing, (i) of the effectiveness of the Registration Statement and
any amendment thereto (including any post-effective amendment), (ii) of the
receipt of any comments from the Commission, (iii) of any request by the
Commission for any amendment to the Registration Statement or any amendment or
supplement to the Prospectus or for additional information, (iv) of the issuance
by the Commission of any stop order suspending the effectiveness of the
Registration Statement or the initiation of any proceedings for that purpose,
and (v) of the issuance by the Commission of an order of suspension or
revocation of the notification on Form N-8A of registration of the Fund as an
Investment Company under the 1940 Act or the initiation of any proceeding for
that purpose. The Fund will make every reasonable effort to prevent the issuance
of any stop order described in subsection (iv) hereunder or any order of
suspension or revocation described in subsection (v) hereunder and, if any such
stop order or order of suspension or revocation is issued, to obtain the lifting
thereof at the earliest possible moment.

     (c)  The Fund will give the Underwriter notice of its intention to file any
amendment to the Registration Statement (including any post-effective amendment)
or any amendment or supplement to the Prospectus (including any revised
prospectus which the Fund proposes for use by the Underwriter in connection with
the offering of the Shares, which differs from the prospectus on file at the
Commission at the time the Registration Statement becomes effective, whether
such revised prospectus is required to be filed pursuant to Rule 497 (b) or Rule
497 (h) of the Rules and Regulations), whether pursuant to the 1940 Act, the
1933 Act, or otherwise, and will furnish the Underwriter with copies of any such
amendment or supplement a reasonable amount of time prior to such proposed
filing or use, as the case may be, and will not file any such amendment or
supplement to which the Underwriter shall reasonably object.

     (d)  The Fund will deliver to the Underwriter, as soon as practicable, two
signed copies of the notification of registration and registration statement as
originally filed and of each amendment thereto, in each case with two sets of
the exhibits filed therewith, and will also deliver to the Underwriter a
conformed copy of the registration statement as originally filed and of each
amendment thereto (but without exhibits to the registration statement or any
such amendment) for the Underwriter.

     (e)  The Fund will furnish to the Underwriter, from time to time during the
period when the Prospectus is required to be delivered under the 1933 Act, such
number of copies of the Prospectus (as amended or supplemented) as the
Underwriter may reasonably request for the purposes contemplated by the 1933 Act
or the Rules and Regulations.

     (f)  If any event shall occur as a result of which it is necessary, in the
opinion of counsel for the Underwriter, to amend or supplement the Prospectus in
order to make the Prospectus not misleading in the light of the circumstances
existing at the time it is delivered to a purchaser, the Fund will forthwith
amend or supplement the Prospectus by preparing and furnishing to the
Underwriter a reasonable number of copies of an amendment or amendments of

                                       7
<PAGE>

or a supplement or supplements to, the Prospectus (in form and substance
satisfactory to counsel for the Underwriter, so that, as so amended or
supplemented, the Prospectus will not contain an untrue statement of a material
fact or omit to state a material fact necessary in order to make the statements
therein, in the light of the circumstances existing at the time the Prospectus
is delivered to a purchaser, not misleading.

     (g)  The Fund will endeavor, in cooperation with the Underwriter, to
qualify the Shares for offering and sale under the applicable securities laws of
such states and other jurisdictions of the United States as the Underwriter may
designate, and will maintain such qualifications in effect for a period of not
less than one year after the date hereof. The Fund will file such statements and
reports as may be required by the laws of each jurisdiction in which the Shares
have been qualified as above provided.

as practicable, but no later than 60 days after the close of the period covered
thereby, an earnings statement (in form complying with the provisions of Rule
158 of the Rules and Regulations) covering a twelve-month period beginning not
later than the first day of the Fund's fiscal quarter next following the
"effective" date (as defined in said Rule 158) of the Registration Statement.

     (i)  Between the date of this Agreement and the termination of any trading
restrictions or Closing Time, whichever is later, the Fund will not, without
your prior consent, offer or sell, or enter into any agreement to sell, any
equity or equity related securities of the Fund other than the Shares and shares
of Common Stock issued in reinvestment of dividends or distributions.

     (j)  If, at the time that the Registration Statement becomes effective, any
information shall have been omitted therefrom in reliance upon Rule 430A of the
Rules and Regulations, then immediately following the execution of the Pricing
Agreement, the Fund will prepare, and file or transmit for filing with the
Commission in accordance with such Rule 430A and Rule 497(h) of the Rules and
Regulations, copies of amended Prospectus, or, if required by such Rule 430A, a
post-effective amendment to the Registration Statement (including an amended
Prospectus), containing all information so omitted.

     (k)  The Fund will use its best efforts to effect the listing of the Shares
on the New York Stock Exchange so that trading on such Exchange will begin no

amendments or supplements thereto, (vii) the printing and delivery to the
Underwriter of copies of the Blue Sky Survey, (viii) the fees and expenses
incurred with respect to the filing with the National Association of Securities

provisions of Section 5 or Section 9 (a) (i) , the Fund or the Adviser shall
reimburse the Underwriter for all of their reasonable out-of-pocket expenses,
including the reasonable fees and disbursements of counsel for the Underwriter.
In the event the transactions contemplated hereunder are not consummated, the

post-effective amendment providing such information shall have been promptly
filed and declared effective in accordance with the requirements of Rule 430A of
the Rules and Regulations.

                consummation of the transactions contemplated herein and therein
                will not conflict with or constitute a breach of, or default
                under, or result in the creation or imposition of any lien,
                charge or encumbrance upon any property or assets of the Fund
                pursuant to, any contract, indenture, mortgage, loan agreement,
                note, lease or other instrument to which the Fund is a party or
                by which it may be bound or to which any of the property or
                assets of the Fund is subject, nor will such action result in
                any violation of the provisions of the Declaration of Trust or
                By-Laws of the Fund, or any law or administrative regulation,
                or, to the best of their knowledge and information,

                        (xii)  The Fund is registered with the Commission under
                the 1940 Act as a closed-end nondiversified management
                investment company, and all required action has been taken by
                the Fund under the 1933 Act, the 1940 Act and the Rules and
                Regulations to make the public offering and consummate the sale
                of the Shares pursuant to this Agreement; the provisions of the

                law as to which no opinion need be rendered), to the extent that
                it constitutes matters of law or legal conclusions, has been
                reviewed by them and is correct in all material respects.

                        (i)  The information in the Prospectus under the caption
                "Taxes", to the extent that it constitutes matters of
                Pennsylvania law or legal conclusions involving matters of
                Pennsylvania law, has been reviewed by them and is correct in
                all material respects.

<PAGE>

                        (ii) Nothing has come to their attention that would lead
                them to believe that the information in the Registration
                Statement under the caption "Investment Objective and Policies -
                Special Considerations Relating to Pennsylvania Municipal Bonds"
                and in Appendix I entitled "Economic Conditions in
                Pennsylvania", at the time it became effective or at the
                Representation Date, contained an untrue statement of a material
                fact or omitted to state a material fact required to be stated
                therein or necessary to make the statements therein not
                misleading or that the information under such caption and in
                such appendix in the Prospectus, at the Representation Date
                (unless the term "Prospectus" refers to a prospectus which has
                been provided to the Underwriter by the Fund for use in
                connection with the offering of the Shares which differs from
                the Prospectus on file at the Commission at the time the
                Registration Statement becomes effective, in which case at the
                time they are first provided to the Underwriter for such use) or
                at Closing Time, included an untrue statement of a material fact
                or omitted to state a material fact necessary in order to make
                the statements therein, in the light of the circumstances under
                which they were made, not misleading.

                (3)  The favorable opinion, dated as of Closing Time, of Philip
     L. Kirstein, Esq., General Counsel to the Adviser, in form and substance
     satisfactory to counsel for the Underwriter, to the effect that:

                        (i)  The Adviser has been duly organized as a
                corporation under the laws of the State of Delaware with
                corporate power and authority to conduct its business as
                described in the Registration Statement and the Prospectus.

                        (ii) The Adviser is duly registered as an investment
                adviser under the Advisers Act and is not prohibited by the
                Advisers Act or the 1940 Act, or the rules and regulations under
                such Acts, from acting under the Advisory Agreement for the Fund
                as contemplated by the Prospectus.

                        (iii)  This Agreement and the Advisory Agreement have
                been duly authorized, executed and delivered by the Adviser, and
                the Advisory Agreement constitutes a valid and binding
                obligation of the Adviser, enforceable in accordance with its
                terms, subject, as to enforcement, to bankruptcy, insolvency,
                reorganization or other laws relating to or affecting creditors'
                rights and to general equity principles; and, to the best of his
                knowledge and information, neither the execution and delivery of
                this Agreement or the Advisory Agreement nor the performance by
                the Adviser of its obligations hereunder or thereunder will
                conflict with, or result in a breach of, any of the terms and
                provisions of, or constitute, with or without giving notice or
                lapse of time or both, a default under, any agreement or
                instrument to which the Adviser is a party or by which the
                Adviser is bound, or any law, order, rule or regulation
                applicable to the Adviser of any jurisdiction, court, federal or
                state regulatory body,

                                       12
<PAGE>

                administrative agency or other governmental body, stock exchange
                or securities association having jurisdiction over the Adviser
                or its properties or operations.

                        (iv) To the best of his knowledge and information, the
                description of the Adviser in the Registration Statement and the
                Prospectus does not contain any untrue statement of a material
                fact or omit to state any material fact required to be stated
                therein or necessary to make the statements therein not
                misleading.

                (4)  In giving their opinion required by sub-section (b)(1) of
     this Section, Brown & Wood shall additionally state that nothing has come
     to their attention that would lead them to believe that the Registration
     Statement (other than the financial statements included therein, as to
     which no opinion need be rendered), at the time it became effective or at
     the Representation Date, contained an untrue statement of a material fact
     or omitted to state a material fact required to be stated therein or
     necessary to make the statements therein not misleading or that the
     Prospectus (other than the financial statement included therein, as to
     which no opinion need be rendered), at the Representation Date (unless the
     term "Prospectus" refers to a prospectus which has been provided to the
     Underwriter by the Fund for use in connection with the offering of the
     Shares which differs from the Prospectus on file at the Commission at the
     time the Registration Statement becomes effective, in which case at the
     time they are first provided to the Underwriter for such use) or at Closing
     Time, included an untrue statement of a material fact or omitted to state a
     material fact necessary in order to make the statements therein, in the
     light of the circumstances under which they were made, not misleading. In
     giving their opinion, Brown & Wood may rely as to matters involving the
     laws of the Commonwealth of Massachusetts upon the opinion of Bingham, Dana
     & Gould. Bingham, Dana & Gould and Brown & Wood may rely, as to matters of
     fact, upon certificates and written statements of officers and employees of
     and accountants for the Fund and the Adviser and of public officials.

     (c)  At Closing Time, (i) the Registration Statement and the Prospectus
shall contain all statements which are required to be stated therein in
accordance with the 1933 Act, the 1940 Act and the Rules and Regulations and in
all material respects shall conform to the requirements of the 1933 Act, the
1940 Act and the Rules and Regulations and the Prospectus shall not contain any
untrue statement of a material fact or omit to state any material fact necessary
to make the statements therein, in the light of the circumstances under which
they were made, not misleading, and no action, suit or proceeding at law or in
equity shall be pending or, to the knowledge of the Fund or the Adviser,
threatened against the Fund or the Adviser which would be required to be set
forth in the Prospectus other than as set forth therein, (ii) there shall not
have been, since the respective dates as of which information is given in the
Registration Statement and the Prospectus, any material adverse change in the
condition, financial or otherwise, of the Fund or in its earnings, business
affairs or business prospects, whether or not arising in the ordinary course of
business, from that set forth in the Registration Statement and Prospectus,
(iii) the Adviser shall have the financial resources available to it necessary
for the

                                       13
<PAGE>

performance of its services and obligations as contemplated in the Registration
Statement and the Prospectus and (iv) no proceedings shall be pending or, to the
knowledge of the Fund or the Adviser, threatened against the Fund or the Adviser
before or by any Federal, state or other commission, board or, administrative
agency wherein an unfavorable decision, ruling or finding would materially and
adversely affect the business, property, financial condition or income of either
the Fund or the Adviser other than as set forth in the Registration Statement
and the Prospectus; and the Underwriter shall have received, at Closing Time, a
certificate of the President or Treasurer of the Fund and of the President or a
Vice President of the Adviser dated as of Closing Time, evidencing compliance
with the appropriate provisions of this subsection (c).

     (d)  At Closing Time, the Underwriter shall have received certificates,
dated as of Closing Time, (i) of the President or Treasurer of the Fund to the
effect that the representations and warranties of the Fund contained in Section
1(a) are true and correct with the same force and effect as though expressly
made at and as of Closing Time and, (ii) of the President or a Vice President of
the Adviser to the effect that the representations and warranties of the Adviser
contained in sections 1(a) and (b) are true and correct with the same force and
effect as though expressly made at and as of Closing Time.

     (e)  At the time of execution of this Agreement, the Underwriter shall have
received from Deloitte & Touche a letter, dated such date in form and substance
satisfactory to the Underwriter, to the effect that:

                (i)  they are independent accountants with respect to the Fund
        within the meaning of the 1933 Act and the Rules and Regulations;

                (ii) in their opinion, the statement of assets and liabilities
        examined by them and included in the Registration Statement complies as
        to form in all material respects with the applicable accounting
        requirements of the 1933 Act and the 1940 Act and the Rules and
        Regulations; and

                (iii)  they have performed specified procedures, not
        constituting an audit, including a reading of the latest available
        interim financial statements of the Fund, a reading of the minute books
        of the Fund, inquiries of officials of the Fund responsible for
        financial accounting matters and such other inquiries and procedures as
        may be specified in such letter, and on the basis of such inquiries and
        procedures nothing came to their attention that caused them to believe
        that at the date of the latest available statement of assets and
        liabilities read by such accountants, or at a subsequent specified date
        not more than five days prior to the date of this Agreement, there was
        any change in the capital stock or net assets of the Fund as compared
        with amounts shown on the statement of net assets included in the
        Prospectus.

     (f)  At Closing Time, the Underwriter shall have received from Deloitte &
Touche a letter, dated as of Closing Time, to the effect that they reaffirm the
statements made in the letter furnished pursuant to subsection (e) of this
Section, except that the "specified date" referred to shall be a date not more
than five days prior to Closing Time.

                                       14
<PAGE>

     (g)  At Closing Time, all proceedings taken by the Fund and the Adviser in
connection with the organization and registration of the Fund under the 1940 Act
and the issuance and sale of the Shares as herein and therein contemplated shall
be satisfactory in form and substance to the Underwriter.

     (h)  In the event the Underwriter exercises its option provided in Section
2 hereof to purchase all or any portion of the Option Shares, the
representations and warranties of the Fund and the Adviser contained herein and
the statements in any certificate furnished by the Fund and the Adviser
hereunder shall be true and correct as of each Date of Delivery, and the
Underwriter shall have received:

                (1)  Certificates, dated the Date of Delivery, of the President
        or Treasurer of the Fund and of the President or a Vice President of the
        Adviser confirming that the information contained in the certificate
        delivered by each of them at Closing Time pursuant to Sections 5(c) and
        (d), as the case may be, remains true as of such Date of Delivery.

                (2)  The favorable opinion of Brown & Wood LLP, counsel for the
        Fund, Stradley, Ronon, Stevens & Young, special Pennslyvania counsel for
        the Fund and Philip L. Kirstein, Esq., General Counsel to the Adviser,
        each in form and substance satisfactory to the Underwriter, dated such
        Date of Delivery, relating to the option Shares and otherwise to the
        same effect as the opinions required by Sections 5(b)(1), (2) and (3),
        respectively.

                (3)  A letter from Deloitte & Touche, in form and substance
        satisfactory to the Underwriter and dated such Date of Delivery,
        substantially the same in scope and substance as the letter furnished to
        the Underwriter pursuant to Section 5(e), except that the "specified
        date" in the letter furnished pursuant to this Section 5(h)(3) shall be
        a date not more than five days prior to such Date of Delivery.

     If any condition specified in this Section shall not have been fulfilled
when and as required to be fulfilled, this Agreement may be terminated by the
Underwriter by notice to the Fund at any time at or prior to Closing Time, and
such termination shall be without liability of any party to any other party
except as provided in Section 4.

     SECTION 6.  Indemnification.  (a)  The Fund and the Adviser, jointly and
severally, agree to indemnify and hold harmless the Underwriter and each person,
if any, who controls the Underwriter within the meaning of Section 15 of the
1933 Act as follows:

                (i)  against any and all loss, liability, claim, damage and
        expense whatsoever, as incurred, arising out of any untrue statement or
        alleged untrue statement of a material fact contained in the
        Registration Statement (or any amendment thereto), including the
        information deemed to be part of the Registration Statement pursuant to
        Rule 430A of the Rules and Regulations, if applicable, or the omission
        or alleged omission therefrom of a material fact required to be stated
        therein or necessary to make the statements therein not misleading or
        arising out of any untrue statement or alleged untrue statement of a

                                       15
<PAGE>

        material fact contained in any preliminary prospectus or the Prospectus
        (or any amendment or supplement thereto) or the omission or alleged
        omission therefrom of a material fact necessary in order to make the
        statements therein, in the light of the circumstances under which they
        were made, not misleading;

                (ii) against any and all loss, liability, claim, damage and
        expense whatsoever as incurred to the extent of the aggregate amount
        paid in settlement of any litigation, or investigation or proceeding by
        any governmental agency or body, commenced or threatened, or of any
        claim whatsoever based upon any such untrue statement or omission, or
        any such alleged untrue statement or omission, if such settlement is
        effected with the written consent of the indemnifying party; and

                (iii)  against any and all expense whatsoever (including the
        fees and disbursements of counsel chosen by the Underwriter) reasonably
        incurred in investigating, preparing or defending against any
        litigation, or investigation or proceeding by any governmental agency or
        body, commenced or threatened, or any claim whatsoever based upon any
        such untrue statement or omission, or any such alleged untrue statement
        or omission, to the extent that any such expense is not paid under (i)
        or (ii) above;

provided, however, that this indemnity agreement does not apply to any loss,
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Fund by the
Underwriter expressly for use in the Registration Statement (or any amendment
thereto) or any preliminary prospectus or the Prospectus (or any amendment or
supplement thereto).

     (b)  The Underwriter agrees, severally and not jointly, to indemnify and
hold harmless the Fund and the Adviser, their respective trustees and directors,
each of the Fund's officers who signed the Registration Statement, and each
person, if any, who controls the Fund or the Adviser within the meaning of
Section 15 of the 1933 Act, against any and all loss, liability, claim, damage
and expense described in the indemnity contained in subsection (a) of this
Section, as incurred, but only with respect to untrue statements or omissions,
or alleged untrue statements or omissions, made in the Registration Statement
(or any amendment thereto) or any preliminary prospectus or the Prospectus (or
any amendment or supplement thereto) in reliance upon and in conformity with
written information furnished to the Fund by the Underwriter expressly for use
in the Registration Statement (or any amendment thereto) or any preliminary
prospectus or the Prospectus (or any amendment or supplement thereto).

     (c)  In addition to the foregoing indemnification, the Adviser also agrees
to indemnify and hold harmless the Underwriter and each person, if any, who
controls the Underwriter within the meaning of Section 15 of the 1933 Act,
against any and all loss, liability, claim, damage and expense described in the
indemnity contained in subsection (a) of this Section, with respect to any
Omitting Prospectus or any advertising materials approved by the Adviser for use
in connection with the public offering of the Shares.

     (d)  Each indemnified party shall give notice as promptly as reasonably
practicable to each indemnifying party of any action commenced against it in
respect of which indemnity may

                                       16
<PAGE>

be sought hereunder, but failure to so notify an indemnifying party shall not
relieve it from any liability which it may have otherwise than on account of
this indemnity agreement. An indemnifying party may participate at its own
expense in the defense of any such action. In no event shall the indemnifying
parties be liable for the fees and expenses of more than one counsel (in
addition to any local counsel) separate from their own counsel for all
indemnified parties in connection with any one action or separate but similar or
related actions in the same jurisdiction arising out of the same general
allegations or circumstances.

     SECTION 7.  Contribution. In order to provide for just and equitable
contribution in circumstances in which the indemnity agreement provided for in
Section 6 is for any reason held to be unenforceable by the indemnified parties
although applicable in accordance with its terms, the Fund, the Adviser and the
Underwriter shall contribute to the aggregate losses, liabilities, claims,
damages and expenses of the nature contemplated by said indemnity agreement as
incurred by the Fund, the Adviser and the Underwriter, as incurred, in such
proportion that the Underwriter is responsible for that portion represented by
the percentage that the aggregate underwriting compensation payable pursuant to
Section 2 hereof bears to the aggregate initial public offering pride of the
Shares sold under this Agreement and the Fund and the Adviser are responsible
for the balance; provided, however, that no person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. For purposes of this Section, each person, if any, who
controls the Underwriter within the meaning of Section 15 of the 1933 Act shall
have the same rights to contribution as the Underwriter, and each trustee and
director of the Fund and the Adviser, respectively, each officer of the Fund who
signed the Registration Statement, and each person, if any, who controls the
Fund or the Adviser within the meaning of Section 15 of the 1933 Act shall have
the same rights to contribution as the Fund and the Adviser, respectively.

     SECTION 8.  Representations, Warranties and Agreements to Survive Delivery.
All representations, warranties and agreements contained in this Agreement or
the Pricing Agreement, or contained in certificates of officers of the Fund or
the Adviser submitted pursuant hereto, shall remain operative and in full force
and effect, regardless of any investigation made by or on behalf of the
Underwriter or controlling person, or by or on behalf of the Fund or the Adviser
and shall survive delivery of the Shares to the Underwriter.

     SECTION 9.  Termination of Agreement. (a) The Underwriter, by notice to the
Fund, may terminate this Agreement at any time at or prior to Closing Time (i)
if there has been, since the date of this Agreement or since the respective
dates as of which information is given in the Registration Statement, any
material adverse change in the condition, financial or otherwise, or in the
earnings, business affairs or business prospects of the Fund or the Adviser,
whether or not arising in the ordinary course of business, or (ii) if there has
occurred any material adverse change in the financial markets in the United
States or elsewhere or any outbreak of hostilities or other calamity or crisis
or any escalation of existing hostilities the effect of which is such as to make
it, in the Underwriter's judgment, impracticable to market the Shares or enforce
contracts for the sale of the Shares, or (iii) if trading in the Common Stock
has been suspended by the Commission or if trading generally on either the
American Stock Exchange or the New York Stock Exchange has been suspended, or
minimum or maximum prices for trading have been fixed, or maximum ranges for
prices for securities have been required, by either of said

                                       17
<PAGE>

exchanges or by order of the Commission or any other governmental authority, or
if a banking moratorium has been declared by Federal or New York authorities.

     (b)  If this Agreement is terminated pursuant to this Section, such
termination shall be without liability of any party to any other party except as
provided in Section 4.

     SECTION 10.  Notices. All notices and other communications hereunder shall
be in writing and shall be deemed to have been duly given if mailed or

the Pricing Agreement is intended or shall be construed to give any person, firm

and the controlling persons and officers, directors and trustees referred to in
Sections 6 and 7 and their heirs and legal representatives, any legal or
equitable right, remedy or claim under or in respect of this Agreement or any

Agreement is executed by or on behalf of the trustees of the Fund solely in
their capacity as such trustees, and shall not constitute their personal
obligation either jointly or severally in their individual capacities. No

of the Fund under this instrument and the Fund shall be solely liable therefor;
all parties hereto shall look solely to the Fund property for the payment of any

     The Fund has filed with the Securities and Exchange Commission (the
"Commission") a notification on Form N-8A of registration of the Fund as an
investment company under the Investment Company Act of 1940, as amended (the
"1940 Act"), and a registration statement on Form N-2 (No. 33-53616) and a
related preliminary prospectus for the registration of the Shares under the
Securities Act of 1933, as amended (the "1933 Act"), and the 1940 Act, and the
rules and regulations of the Commission under the 1933 Act and the 1940 Act (the
"Rules and Regulations") and has filed such amendments to such registration
statement on Form N-2, if any, and such amended preliminary prospectuses as may
have been required to the date hereof.  The Fund will prepare and file such
additional amendments thereto and such amended prospectuses as may hereafter be
required.  Such registration statement (as amended at the time it becomes
effective, if applicable) and the prospectus constituting a part thereof
(including in each case the information, if any, deemed to be part thereof
pursuant to Rule 430A(b) of the Rules and Regulations), as from time to time
amended or supplemented pursuant to the 1933 Act, are hereinafter referred to as
the "Registration Statement" and the "Prospectus," respectively, except that if
any revised prospectus shall be provided to the Underwriter by the Fund for use
in connection with the offering of the shares which differs from the Prospectus
on file at the Commission at the time the Registration Statement becomes
effective (whether such revised prospectus is required to be filed by the Fund
pursuant to Rule 497(b) or Rule 497(h) of the Rules and Regulations) the term
"Prospectus" shall refer to such revised prospectus from and after the time it
is first provided to the Underwriter for such use.

     The Fund understands that the Underwriter proposes to make a public
offering of the Shares as soon as the Underwriter deems advisable after the
Registration Statement becomes effective and the Pricing Agreement has been
executed and delivered.

     to make the statements therein not misleading.  At the time the
     Registration Statement becomes effective, at the Representation Date and at
     Closing Time as defined in Section 2, the Prospectus (unless the term
     "Prospectus" refers to a prospectus which has been provided to the
     Underwriter by the Fund for use in connection with the offering of the

     time the Registration Statement becomes effective, in which case at the
     time it is first provided to the Underwriter for such use) will not contain
     an untrue statement of a material fact or omit to state a material fact
     necessary in order to make the statements therein, in the light of the
     circumstances under which they were made, not misleading; provided,

     agreement, note, lease or other instrument to which the Fund is a party or

  SECTION 2.  Sale and Delivery to the Underwriter; Closing.
              ---------------------------------------------

  (a)  On the basis of the representations and warranties herein contained and

     sell the Shares to the Underwriter, and the Underwriter agrees to purchase
     the Shares from the Fund, at the price per share set forth in the Pricing
     Agreement.

        (i)  If the Fund has elected not to rely upon rule 430A under the Rules
     and Regulations, the initial public offering price and the purchase price

     Regulations, the purchase price pet share to be paid by the Underwriter for
     the Shares shall be an amount equal to the initial public offering price,

     Underwriter and the Fund.  The initial public offering price and the

     liability of any party to any other party, except as provided in Section 5,

     upon by the Underwriter and the Fund, at 10:00 A.M. on the fifth business
     day following the date the Registration Statement becomes effective (or, if
     the Fund has elected to rely upon rule 430A under the Rules and
     Regulations, the fifth business day after execution of the Pricing
     Agreement), or such other time not later than ten business days after such
     date as shall be agreed upon by the Underwriter and the Fund (such time and
     date of payment and delivery being herein called "Closing Time").  Payment
     shall be made

                                       6
<PAGE>

     to the Fund by Federal fund check or checks or similar same-day funds and

  SECTION 3.  Covenants of the Fund.  The Fund covenants with the Underwriter as
              ---------------------
follows:

  (a)  The Fund will use its best efforts (i) to cause the Registration
     Statement to become effective under the 1933 Act and will advise the
     Underwriter promptly as to the time at which the Registration Statement and
     any amendments thereto (including any post-effective amendment) becomes so
     effective and (ii) if required, to cause the issuance of any orders
     exempting the Fund from any provisions of the 1940 Act and will advise the
     Underwriter promptly as to the time at which any such orders are granted.

  (b)  The Fund will notify the Underwriter immediately, and confirm the notice
     in writing, (i) of the effectiveness of the Registration Statement and any
     amendments thereto (including any post-effective amendment), (ii) of the
     receipt of any comments from the Commission, (iii) of any request by the
     Commission for any amendment to the Registration Statement or any amendment
     or supplement to the Prospectus or for additional information, (iv) of the
     issuance by the Commission of any stop order suspending the effectiveness
     of the Registration Statement or the initiation of any proceedings for that
     purpose and (v) of the issuance by the Commission of an order of suspension
     or revocation of the notification on Form N-8A of registration of the Fund
     as an investment company under the 1940 Act or initiation of any proceeding
     for that purpose. The Fund will make every reasonable effort to prevent the
     issuance of any stop order described in subsection (iv) hereunder or any
     order of suspension or revocation described in subsection (v) hereunder
     and, if any stop order or order of suspension or revocation is issued, to
     obtain the lifting thereof at the earliest possible moment.

  (c)  The Fund will give the Underwriter notice of its intention to file any
     amendment to the Registration Statement (including any post-effective
     amendment) or any amendment or supplement to the Prospectus (including any
     revised prospectus which the Fund proposes for use by the Underwriter in
     connection with the offering of the Shares which differs from the
     prospectus on file at the Commission at the time the Registration Statement
     becomes effective, whether such revised prospectus is required to be filed
     pursuant to Rule 497(b) or Rule 497(h) of the Rules and Regulations)
     whether pursuant to the 1940 Act, the 1933 Act, or otherwise, and will
     furnish the Underwriter with copies of any such amendment or supplement a
     reasonable amount of time prior to such proposed filing or use, as the case
     may be, and will not file any such amendment or supplement to which the
     Underwriter or counsel for the Underwriter shall reasonably object.

  (d)  The Fund will deliver to the Underwriter, as soon as practicable, two
     signed copies of the registration statement as originally filed and of each
     amendment thereto, in each case with two sets of the exhibits filed
     therewith, and will also deliver to the Underwriter a

                                       7
<PAGE>

     conformed copy of the registration statement as originally filed and of
     each amendment thereto (but without exhibits to the registration statement
     or to any such amendment) for the Underwriter.

  (e)  The Fund will furnish to the Underwriter, from time to time during the
     period when the Prospectus is required to be delivered under the 1933 Act,
     such number of copies of the Prospectus (as amended or supplemented) as the
     Underwriter may reasonably request for the purposes contemplated by the
     1933 Act or the Rules and Regulations.

  (f)  If any event shall occur as a result of which it is necessary, in the
     opinion of counsel for the Underwriter, to amend or supplement the
     Prospectus in order to make the Prospectus not misleading in the light of
     the circumstances existing at the time it is delivered to a purchaser, the
     Fund will forthwith amend or supplement the Prospectus by preparing and
     furnishing to the Underwriter a reasonable number of copies of an amendment
     or amendments of, or a supplement or supplements to, the Prospectus (in
     form and substance satisfactory to counsel for the Underwriter), so that,
     as so amended or supplemented, the Prospectus will not contain an untrue
     statement of a material fact or omit to state a material fact necessary in
     order to make the statements therein, in the light of the circumstances
     existing at the time the Prospectus is delivered to a purchaser, not
     misleading.

  (g)  The Fund will endeavor, in cooperation with the Underwriter, to qualify
     the Shares for offering and sale under the applicable securities laws of
     such states and other jurisdictions of the United States as the Underwriter
     may designate and will maintain such qualifications in effect for a period
     of not less than one year after the date hereof. The Fund will file such
     statements and reports as may be required by the laws of each jurisdiction
     in which the Shares have been qualified as above provided.

  (h)  The Fund will make generally available to its security holders as soon as
     practicable, but not later than 60 days after the close of the period
     covered thereby, an earnings statement (in form complying with the
     provisions of Rule 158 of the Rules and Regulations) covering a twelve-
     month period beginning not later than the first day of the Fund's fiscal
     quarter next following the "effective" date (as defined in said Rule 158)
     of the Registration Statement.

  (i)  Between the date of this Agreement and the termination of any trading
     restrictions or Closing Time, whichever is later, the Fund will not,
     without your prior consent, offer or sell or enter into any agreement to
     sell any equity or equity related securities of the Fund other than the
     Shares and Common Shares issued in reinvestment of dividends or
     distributions.

  (j)  If, at the time that the Registration Statement becomes effective, any
     information shall have been omitted therefrom in reliance upon Rule 430A of
     the Rules and Regulations, then immediately following the execution of the
     Pricing Agreement, the Fund will prepare and file or transmit for filing
     with the Commission in accordance with such Rule 430A and Rule 497(h) of
     the Rules and Regulations, copies of an amended Prospectus or, if required
     by such Rule 430A, a post-effective amendment to the Registration Statement
     (including an amended Prospectus) containing all information so omitted.

                                       8
<PAGE>

  (k)  The Fund will use its best efforts to maintain its qualification as a
     regulated investment company under Subchapter M of the Code.

  SECTION 4.  Covenants of the Underwriter.  The Underwriter covenants and
              ----------------------------
agrees with the Fund as follows:

  (a)  It will sell Shares only to a person who has agreed to execute and
     deliver, whose Broker-Dealer (as defined in the Prospectus) has agreed to
     execute and deliver or who has already executed and delivered a Master
     Purchaser's Letter (as defined in the Prospectus) in accordance with the
     terms of the Prospectus.

  (b)  No later than Closing Time, it will execute and deliver a Master
     Purchaser's Letter in accordance with the terms of the Prospectus.

     been promptly filed and declared effective in accordance with the
     requirements of Rule 430A of the Rules and Regulations.

             (3)  The Fund is duly qualified to transact business and is in good

     validly issued and are fully paid and non-assessable.

             (5)  The Shares have been duly authorized for issuance and sale to

             (7)  The Registration Statement is effective under the 1933 Act
     and, to the best of their knowledge and information, no stop order
     suspending the effectiveness of the Registration Statement has been issued
     under the 1933 Act, and no proceedings for that purpose have been
     instituted, are pending or are contemplated.

             (8)  At the time the Registration Statement became effective and at
     the Representation Date, the Registration Statement (other than the
     financial statements included therein, as to which no opinion need be

     required under state securities laws; and to the best of their knowledge
     and information, the execution and delivery of this Agreement, the Pricing
     Agreement, the Advisory Agreement, the Custodian Agreement, the Auction
     Agreement and the Depository Agreement and the consummation of the
     transactions contemplated herein and therein will not conflict with or
     constitute a breach of, or default under, or result in the creation or
     imposition of any lien, charge or encumbrance upon any property or assets
     of the Fund pursuant to any contract, indenture, mortgage, loan agreement,
     note, lease or other instrument to which the Fund is a party or by which it
     may be bound or to which any of the property or assets of the Fund is
     subject, nor will such action result in any violation of the provisions of
     the Declaration of Trust or By-Laws of the Fund, or any law, administrative
     regulation or administrative or court decree.

             (12) The Advisory Agreement and the Custodian Agreement have each
     been duly authorized, executed and delivered by the Fund, and each complies
     with all applicable provisions of the 1940 Act.

<PAGE>

             (13) The Fund is registered with the Commission under the 1940 Act
     as a closed-end, non-diversified management investment company, and all
     required action has been taken by the Fund under the 1933 Act, the 1940 Act
     and the Rules and Regulations to make the public offering and consummate
     the sale of the Shares pursuant to this Agreement; the provisions of the
     Declaration of Trust and By-Laws of the Fund comply as to form in all
     material respects with the requirements of the 1940 Act; and, to the best
     of their knowledge and information, no order of suspension or revocation of
     such registration under the 1940 Act, pursuant to Section 8(e) thereof, has
     been issued or proceedings therefor initiated or threatened by the
     Commission.

             (14) The information in the Prospectus under the caption "Taxes"
     (other than information related to Pennsylvania law, as to which no opinion
     need be rendered), to the extent that it constitutes matters of law or
     legal conclusions, has been reviewed by them and is correct in all material
     respects.

             (15) The Auction Agreement and the Depository Agreement each have
     been duly authorized, executed and delivered by the Fund, and each
     constitutes a valid and binding obligation of the Fund, enforceable in
     accordance with its terms, subject, as to enforcement, to bankruptcy,
     insolvency, reorganization or other laws relating to or affecting
     creditors' rights and to general equity principles.

        (ii) The favorable opinion, dated as of Closing Time, of Stradley,
     Ronon, Stevens & Young Special Counsel for the Fund, to the effect that:

             (1)  The information in the Prospectus under the caption "Taxes",
     to the extent that it constitutes matters of Pennsylvania law or legal
     conclusions or legal opinions involving matters of law, has been reviewed
     by them and is correct in all material respects.

             (2)  Nothing has come to their attention that would lead them to
     believe that the information in the Registration Statement under the
     caption "Investment Objective and Policies -- Special Considerations
     Relating to Pennsylvania Municipal Bonds" and in Appendix A entitled
     "Economic Conditions in Pennsylvania", at the time it became effective or
     at the Representation Date, contained an untrue statement of a material
     fact or omitted to state a material fact required to be stated therein or
     necessary to make the statements therein not misleading or that the
     information under such caption and in such appendix in the Prospectus, at
     the Representation Date (unless the term "Prospectus" refers to a
     prospectus which has been provided to the Underwriter by the Fund for use
     in connection with the offering of the Shares which differs from the
     Prospectus on file at the Commission at the time the Registration Statement
     becomes effective, in which case at the time they are first provided to the
     Underwriter for such use) or at Closing Time, included an untrue statement
     of a material fact or omitted to state a material fact necessary in order
     to make the statements therein, in the light of the circumstances under
     which they were made, not misleading.

                                       12
<PAGE>

  (iii)  The favorable opinion, dated as of Closing Time, of Philip L. Kirstein,
Esq., General Counsel to the Adviser, in form and substance satisfactory to
counsel for the Underwriter, to the effect that:

        (1)  The Adviser has been duly organized as a corporation under the laws
     of the State of Delaware with corporate power and authority to conduct its
     business as described in the Registration Statement and the Prospectus.

        (2)  The Adviser is duly registered as an investment adviser under the
     Advisers Act and is not prohibited by the Advisers Act or the 1940 Act or
     the rules and regulations under such Acts from acting under the Advisory
     Agreement for the Fund as contemplated by the Prospectus.

        (3)  This Agreement has been duly authorized, executed and delivered by
     the Adviser; the Advisory Agreement is in fully force and effect and
     constitutes a valid and binding obligation of the Adviser, enforceable in
     accordance with its terms, subject, as to enforcement, to bankruptcy,
     insolvency, reorganization or other laws relating to or affecting
     creditors' rights and to general equity principles, and, to the best of his
     knowledge and information, neither the execution and delivery of this
     Agreement or the Advisory Agreement nor the performance by the Adviser of
     its obligations hereunder or thereunder will conflict with, or result in a
     breach of, any of the terms and provisions of, or constitute, with or
     without giving notice of lapse of time or both, a default under, any
     agreement or instrument to which it is a party or by which the Adviser is
     bound, or any law, order, rule or regulations applicable to the Adviser of
     any jurisdiction, court, Federal or state regulatory body, administrative
     agency or other governmental body, stock exchange or securities association
     having jurisdiction over the Adviser or its respective properties or
     operations.

        (4)  To the best of his knowledge and information, the description of
     the Adviser in the Registration Statement and the Prospectus does not
     contain any untrue statement of a material fact or omit to state any
     material fact required to be stated therein or necessary to make the
     statements therein not misleading.

  (iv) In giving their opinion required by subsection (b)(i) of this Section,
Brown & Wood shall additionally state that nothing has come to their attention
that would lead them to believe that the Registration Statement (excluding the
financial statements and financial schedules included therein, as to which such
counsel need express no belief), at the time it became effective or at the
Representation Date, contained an untrue statement of a material fact or omitted
to state a material fact required to be stated therein or necessary to make the
statements therein not misleading or that the Prospectus (except for the
financial statements and financial schedules included therein as to which such
counsel need express no belief), at the Representation Date (unless the term
"Prospectus" refers to a prospectus which has been provided to the Underwriter
by the Fund for use in connection with the offering of the Shares which differs
from the Prospectus on file at the Commission at the time the Registration
Statement becomes effective, in which case at


                                       13
<PAGE>

the time it is first provided to the Underwriter for such use) or at Closing
Time, included an untrue statement of a material fact or omitted to state a
material fact necessary in order to make the statements therein, in the light of
the circumstances under which they were made, not misleading. In giving their
opinion, Brown & Wood may rely, as to all matters governed by the law of The
Commonwealth of Massachusetts, upon the opinion of Bingham, Dana & Gould, and
Brown & Wood may rely, as to matters of fact, upon certificates and written
statements of officers and employees of and accountants of the Fund and the
Adviser and of public officials.

        (c)  At Closing Time (i) the Registration Statement and the Prospectus
     shall contain all statements which are required to be stated therein in
     accordance with the 1933 Act, the 1940 Act and the Rules and Regulations
     and in all material respects shall conform to the requirements of the 1933
     Act, the 1940 Act and the Rules and Regulations, and the Prospectus shall
     not contain any untrue statement of a material fact or omit to state a
     material fact necessary to make the statements therein in the light of the
     circumstances under which they were made, not misleading and no action,
     suit or proceeding at law or in equity shall be pending or, to the
     knowledge of the Fund or the Adviser, threatened against the Fund or the
     Adviser which would be required to be set forth in the Prospectus other
     than as set forth therein, (ii) there shall not have been, since the
     respective dates as of which information is given in the Registration
     Statement and the Prospectus, any material adverse change in the condition,
     financial or otherwise, of the Fund or in its earnings, business affairs or
     business prospects, whether or not arising in the ordinary course of
     business, from that set forth in the Registration Statement and Prospectus,
     (iii) the Adviser shall have the financial resources available to it
     necessary for the performance of its services and obligations as
     contemplated in the Registration Statement and the Prospectus, (iv) no
     proceedings shall be pending or, to the knowledge of the Fund or the
     Adviser, threatened against the Fund or the Adviser before or by any
     Federal, state or other commission, board or administrative agency wherein
     an unfavorable decision, ruling or finding would materially and adversely
     affect the business, property, financial condition or income of either the
     Fund or the Adviser other than as set forth in the Registration Statement
     and the Prospectus and (v) Moody's Investors Service, Inc. ("Moody's") and
     Standard & Poor's Corporation ("S&P") shall have confirmed that the Shares
     have been rated "aaa" and AAA, respectively, by such agencies; and the
     Underwriter shall have received, at Closing Time, a certificate of the
     President or Treasurer of the Fund and of the President or a Vice President
     of the Adviser dated as of Closing Time, evidencing compliance with the
     appropriate provisions of this subsection (c), together with true and
     correct copies of letters from Moody's and S&P confirming their rating.

        (d)  At Closing Time, the Underwriter shall have received certificates,
     dated as of Closing Time, (i) of the President or Treasurer of the Fund to
     the effect that the representations and warranties of the Fund contained in
     Section 1(a) are true and correct with the same force and effect as though
     expressly made at and as of Closing Time and (ii) of the President or a
     Vice President of the Adviser to the effect that the representations and
     warranties of the Adviser contained in Sections 1(a) and (b) are true and
     correct with the same force and effect as though expressly made at and as
     of Closing Time.

                                       14
<PAGE>

        (e)  At the time of execution of this Agreement, the Underwriter shall
     have received from Deloitte & Touche a letter, dated the date hereof, in
     form and substance satisfactory to the Underwriter, to the effect that:

             (i)  they are independent accountants with respect to the Fund
     within the meaning of the 1933 Act and the Rules and Regulations;

             (ii) in their opinion, the statement of assets, liabilities and
     capital examined by them and included in the Registration Statement
     complies as to form in all material respects with the applicable accounting
     requirements of the 1933 Act and 1940 Act and the Rules and Regulations;

             (iii)  they have performed specified procedures, not constituting
an audit, including a reading of the latest available interim financial
statements of the Fund, a reading of the minutes books of the Fund, inquiries of
officials of the Fund responsible for financial accounting matters and such
other inquiries and procedures as may be specified in such letter, and on the
basis of such inquiries and procedures nothing came to their attention that
caused them to believe that (A) the unaudited financial statements as of
November 2, 1992 included in the Registration Statement do not comply as to form
in all material respects with the applicable accounting requirements of the 1933
Act and the 1933 Act Regulations applicable to unaudited interim financial
statements included in registration statements or are not in conformity with
generally accepted accounting principles applied on a basis substantially
consistent with that of the audited financial statements included in the
Registration Statement, and (B) during the period from November 2, 1992 to a
specified date not more than five days prior to the date of this Agreement,
there was any change in the shares of beneficial interest or net assets of the
Fund or any increase in the long-term debt of the Fund, as compared with amounts
shown on the unaudited financial statements included in the Registration
Statement, except for changes which the Registration Statement discloses have
occurred or may occur; and

             (iv) in addition to the procedures referred to in clause (iii)
above, they have performed other specified procedures, not constituting an
audit, with respect to certain amounts, percentages, numerical data, financial
information and financial statements appearing in the Registration Statement,
which have previously been specified by you and which shall be specified in such
letter, and have compared certain of such items with, and have found such items
to be in agreement with, the accounting and financial records of the Fund.

        (f)  At Closing Time, the Underwriter shall have received from Deloitte
     & Touche a letter, dated as of Closing Time, to the effect that they
     reaffirm the statements made in the letter furnished pursuant to subsection
     (e) of this Section, except that the "specified date" referred to shall be
     a date not more than five days prior to closing Time.

        (g)  At Closing Time, counsel for the Underwriter shall have been
     furnished with such documents and opinions as they may reasonably require
     for the purpose of enabling them to pass upon the issuance and sale of the
     Shares as herein contemplated and to pass upon related

                                       15
<PAGE>

     proceedings, or in order to evidence the accuracy of any of the
     representations or warranties, or the fulfillment of any of the conditions,
     herein contained; and all proceedings taken by the Fund and the Adviser in
     connection with the organization and registration of the Fund under the
     1940 Act and the issuance and sale of the Shares as herein contemplated
     shall be satisfactory in form and substance to the Underwriter and counsel
     for the Underwriter.

     If any condition specified in this Section shall not have been fulfilled
when and as required to be fulfilled, this Agreement may be terminated by the
Underwriter by notice to the Fund at any time at or prior to Closing Time, and
such termination shall be without liability of any party to any other party
except as provided in Section 5.

  SECTION 7.  Indemnification.  (a)  The Fund and the Adviser, jointly and
              ---------------
severally, agree to indemnify and hold harmless the Underwriter and each person,
if any, who controls the Underwriter within the meaning of Section 15 of the
1933 Act as follows:

        (i)  against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, arising out of any untrue statement or alleged
     untrue statement of a material fact contained in the Registration Statement
     (or any amendment thereto), including the information deemed to be part of
     the Registration Statement pursuant to Rule 430A of the Rules and
     Regulations, if applicable, or the omission or alleged omission therefrom
     of a material fact required to be stated therein or necessary to make the
     statements therein not misleading or arising out of any untrue statement or
     alleged untrue statement of a material fact contained in any preliminary
     prospectus or the Prospectus (or any amendment or supplement thereto) or
     the omission or alleged omission therefrom of a material fact necessary in
     order to make the statements therein, in the light of the circumstances
     under which they were made, not misleading;

        (ii) against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, to the extent of the aggregate amount paid in
     settlement of any litigation, or investigation or proceeding by any
     governmental agency or body, commenced or threatened, or of any claim
     whatsoever based upon any such untrue statement or omission, or any such
     alleged untrue statement or omission, if such settlement is effected with
     the written consent of the Fund; and

        (iii)  against any and all expenses whatsoever (including the fees and
     disbursements of counsel chosen by the Underwriter) reasonably incurred in
     investigating, preparing or defending against any litigation or
     investigation or proceeding by any governmental agency or body, commenced
     or threatened, or any claim whatsoever based upon any such untrue statement
     or omission, or any such alleged untrue statement or omission, to the
     extent that any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement does not apply to any loss,
- --------  -------
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Fund by the
Underwriter expressly for use in the Registration Statement (or any

                                       16
<PAGE>

amendment thereto) or any preliminary prospectus or the Prospectus (or any
amendment or supplement thereto).

  (b)  The Underwriter agrees to indemnify and hold harmless the Fund and its
     trustees and the Adviser, and its directors, each of the Fund's officers
     who signed the Registration Statement, and each person, if any, who
     controls the Fund or the Adviser within the meaning of Section 15 of the
     1933 Act, against any and all loss, liability, claim, damage and expense
     described in the indemnity contained in subsection (a) of this Section, as
     incurred, but only with respect to untrue statements or omissions, or
     alleged untrue statements or omissions, made in the Registration Statement
     (or any amendment or supplement thereto) or any preliminary prospectus or
     the Prospectus (or any amendment or supplement thereto) in reliance upon
     and in conformity with written information furnished to the Fund by the
     Underwriter expressly for use in the Registration Statement (or any
     amendment thereto) or any preliminary prospectus or the Prospectus (or any
     amendment or supplement thereto).

  (c)  Each indemnified party shall give notice as promptly as reasonably
     practicable to each indemnifying party of any action commenced against it
     in respect of which indemnity may be sought hereunder, but failure to so
     notify an indemnifying party shall not relieve it from any liability which
     it may have otherwise than on account of this indemnity agreement.  An
     indemnifying party may participate at its own expense in the defense of
     such action.  In no event shall the indemnifying parties be liable for the
     fees and expenses of more than one counsel (in addition to any local
     counsel) separate from their own counsel for all indemnified parties in
     connection with any one action or separate but similar or related actions
     in the same jurisdiction arising out of the same general allegations or
     circumstances.

  SECTION 8.  Contribution.  In order to provide for just and equitable
              ------------
contribution in circumstances in which the indemnity agreement provided for in
Section 7 is for any reason held to be unenforceable by the indemnified parties
although applicable in accordance with its terms, the Fund and the Underwriter
shall contribute to the aggregate losses, liabilities, claims, damages and
expenses of the nature contemplated by said indemnity agreement as incurred by
the Fund and the Underwriter, as incurred, in such proportions that the
Underwriter is responsible for that portion represented by the percentage that
the underwriting compensation payable pursuant to Section 2 hereof bears to the
initial public offering price appearing on the cover page of the Prospectus, and
the Fund is responsible for the balance; provided, however, that no person
                                         --------  -------
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the 1933 Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.  Notwithstanding the provisions of
this Section 8, the Underwriter shall not be required to contribute any amount
in excess of the amount by which the total price at which the Shares
underwritten by it and distributed to the public were offered to the public
exceeds the amount of any damages which such Underwriter has otherwise been
required to pay in respect of such losses, liabilities, claims, damages and
expenses.  For purposes of this Section, each person, if any, who controls the
Underwriter within the meaning of Section 15 of the 1933 Act shall have the same

                           STANDARD DEALER AGREEMENT
                           -------------------------

Dear Sirs:

     In connection with public offerings of securities underwritten by us, or by
a group of underwriters (the "Underwriters") represented by us, you may be
offered the opportunity to purchase a portion of such securities, as principal,
at a discount from the offering price representing a selling concession or
reallowance granted as consideration for services rendered by you in the sale of
such securities. We request that you agree to the following terms and
provisions, and make the following representations, which, together with any
additional terms and provisions set forth in any wire or letter sent to you in
connection with a particular offering, will govern all such purchases of
securities and the reoffering thereof by you.

     Your subscription to, or purchase of, such securities will constitute your
reaffirmation of this Agreement.

     1.  When we are acting as representative (the "Representative") of the
Underwriters in offering securities to you, it should be understood that all
offers are made subject to prior sale of the subject securities, when, as and if
such securities are delivered to and accepted by the Underwriters and subject to
the approval of legal matters by their counsel. In such cases, any order from
you for securities will be strictly subject to confirmation and we reserve the
right in our uncontrolled discretion to reject any order in whole or in part.
Upon release by us; you may reoffer such securities at the offering price fixed
by us. With our consent, you may allow a discount, not in excess of the
reallowance fixed by us, in selling such securities to other dealers, provided
that in doing so you comply with the Rules of Fair Practice of the National
Association of Securities Dealers, Inc. (the "NASD"). Upon our request, you will
advise us of the identity of any dealer to whom you allow such a discount and
any Underwriter or dealer from whom you receive such a discount. After the
securities are released for sale to the public, we may vary the offering price
and other selling terms.

     2.  You represent that you are a dealer actually engaged in the investment
banking or securities business and that you are either (i) a member in good
standing of the NASD or (ii) a dealer with its principal place of business
located outside the United States, its territories or possessions and not
registered under the Securities Exchange Act of 1934 (a "non-member foreign
dealer") or (iii) a bank not eligible for membership in the NASD. If you are a
non-member foreign dealer, you agree to make no sales of securities within the
United States, its territories or its possessions or to persons who are
nationals thereof or residents therein. Non-member foreign dealers and banks
agree, in making any sales, to comply with the NASD's interpretation with
respect to free-riding and withholding. In accepting a selling concession
<PAGE>

where we are acting as Representative of the Underwriters, in accepting a
reallowance from us whether or not we are acting as such Representative, and in
allowing a discount to any other person, you agree to comply with the provisions
of Section 24 of Article III of the Rules of Fair Practice of the NASD, and, in
addition, if you are a non-member foreign dealer or bank, you agree to comply,
as though you were a member of the NASD, with the provisions of Sections 8 and
36 of Article III of such Rules of Fair Practice and to comply with Section 25
of Article III thereof as that Section applies to a non-member foreign dealer or
bank. You represent that you are fully familiar with the above provisions of the
Rules of Fair Practice of the NASD.

     3.  If the securities have been registered under the Securities Act of 1933
(the "1933 Act"), in offering and selling such securities, you are not
authorized to give any information or make any representation not contained in
the prospectus relating thereto. You confirm that you are familiar with the
rules and policies of the Securities and Exchange Commission relating to the
distribution of preliminary and final prospectuses, and you agree that you will
comply therewith in any offering covered by this Agreement. If we are acting as
Representative of the Underwriters, we will make available to you, to the extent
made available to us by the issuer of the securities, such number of copies of
the prospectus or offering documents, for securities not registered under the
1933 Act, as you may reasonably request.

     4.  If we are acting as Representative of the Underwriters of securities of
an issuer that is not required to file reports under the Securities Exchange Act
of 1934 (the " 1934 Act"), you agree that you will not sell any of the
securities to any account over which you have discretionary authority.

     5.  Payment for securities purchased by you is to be made at our office,
One Liberty Plaza, 165 Broadway, New York, N.Y. 10006 (or at such other place as
we may advise), at the offering price less the concession allowed to you, on
such date as we may advise, by certified or official bank check in New York
Clearing House funds (or such other funds as we may advise), payable to our
order, against delivery of the securities to be purchased by you. We shall have
authority to make appropriate arrangements for payment for and/or delivery
through the facility of The Depository Trust Company or any such other
depository or similar facility for the securities.

     6.  In the event that, prior to the completion of the distribution of
securities covered by this Agreement, we purchase in the open market or
otherwise any securities, delivered to you, if we are acting as Representative
of the Underwriters, you agree to repay to us for the accounts of the
Underwriters the amount of the concession allowed to you plus brokerage
commissions and any transfer taxes paid in connection with such purchase.

     7.  At any time prior to the completion of the distribution of securities
covered by this Agreement you will, upon our request as Representative of the
Underwriters, report to us the amount of securities purchased by you which then
remains unsold and will, upon our request, sell to us for the account of one or
more of the Underwriters such amount of such unsold securities as we may
designate, at the offering price less an amount to be determined by us not in
excess of the concession allowed to you.

                                       2
<PAGE>

     8.  If we are acting as Representative of the Underwriters, upon
application to us, we will inform you of the states and other jurisdictions of
the United States in which it is believed that the securities being offered are
qualified for sale under, or are exempt from the requirements of, their
respective securities laws, but we assume no responsibility with respect to your
right to sell securities in any jurisdiction. We shall have authority to file
with the Department of State of the State of New York a Further State Notice
with respect to the securities, if necessary.

     9.  You agree that in connection with any offering of securities covered by
this Agreement you will comply with the applicable provisions of the 1933 Act
and the 1934 Act and the applicable rules and regulations of the Securities and
Exchange Commission thereunder, the applicable rules and regulations of the
NASD, and the applicable rules of any securities exchange having jurisdiction
over the offering.

     10.  We shall have full authority to take such action as we may deem
advisable in respect of all matters pertaining to any offering covered by this
Agreement. We shall be under no liability to you except for our lack of good
faith and for obligations assumed by us in this Agreement, except that you do
not waive any rights that you may have under the 1933 Act or the rules and
regulations thereunder.

     11.  Any notice from us shall be deemed to have been duly given if mailed
or transmitted by any standard form of written telecommunications to you at the
above address or at such other address as you shall specify to us in writing.

     12.  With respect to any offering of securities covered by this Agreement,
the price restrictions contained in Paragraph 1 hereof and the provisions of
Paragraphs 6 and 7 hereof shall terminate as to such offering at the close of
business on the 45th day after the securities are released for sale or, as to
any or all such provisions, at such earlier time as we may advise. All other
provisions of this Agreement shall remain operative and in full force and effect
with respect to such offering.

     13.  This Agreement shall be governed by the laws of the State of New York.

     Please confirm your agreement hereto by signing the enclosed duplicate copy
hereof in the place provided below and returning such signed duplicate copy to
us at World Headquarters, North Tower, World Financial Center, New York, N.Y.
10281-1305, Attention:  Corporate Syndicate. Upon receipt thereof, this
instrument and such signed duplicate copy will evidence the agreement between
us.

      transaction involved. The Fund shall cause all oral instructions to be

      of any action by the Board of Directors pursuant to the Articles of
      Incorporation as described in such vote, and such vote may be considered

      of Net Asset Value and Net Income

share.  If so directed, the Custodian shall also calculate weekly the net income

advise the Fund and the Transfer Agent weekly of the total amounts of such net
income and, if instructed in writing by an officer of the Fund to do so, shall
advise the Transfer Agent periodically of the division of such net income among
its various components.  The calculations of the net asset value per share and
the weekly income of the Fund shall be made at the time or times described from
time to time in the Fund's currently effective prospectus.

4.    Records
      -------

     The Custodian shall create and maintain all records relating to its
activities and obligations under this Contract in such manner as will meet the
obligations of the Fund under the Investment Company Act of 1940, with
particular attention to Section 31 thereof and Rules 3la-1


                                     -18-
<PAGE>

and 3la-2 thereunder. All such records shall be the property of the Fund and
shall at all times during the regular business hours of the Custodian be open
for inspection by duly authorized officers, employees or agents of the Fund and
employees and agents of the Securities and Exchange Commission. The Custodian
shall, at the Fund's request, supply the Fund with a tabulation of securities
owned by the Fund and held by the Custodian and shall, when requested to do so
by the Fund and for such compensation as shall be agreed upon between the Fund
and the Custodian, include certificate numbers in such tabulations.

5.    Opinion of Fund's Independent Accountant
      ----------------------------------------

      The Custodian shall take all reasonable action, as the Fund may from time
to time request, to obtain from year to year favorable opinions from the Fund's
independent accountants with respect to its activities hereunder in connection
with the preparation of the Fund's Form N-2, and Form N-SAR or other annual
reports to the Securities and Exchange Commission and with respect to any other
requirements of such Commission.

6.    Reports to Fund by Independent Public Accountants
      -------------------------------------------------

      The Custodian shall provide the Fund, at such times as the Fund may
reasonably require, with reports by independent public accountants on the
accounting system, internal accounting control and procedures for safeguarding
securities, futures contracts and options on futures contracts, including
securities deposited and/or maintained in a Securities System, relating to the
services provided by the Custodian under this Contract; such reports, shall be
of sufficient scope and in sufficient detail, as may reasonably be required by
the Fund to provide reasonable assurance that any material inadequacies would be
disclosed by such examination, and, if there are no such inadequacies, the
reports shall so state.


                                     -19-
<PAGE>

7.    Compensation of Custodian
      -------------------------

      The Custodian shall be entitled to reasonable compensation for its
services and expenses as Custodian, as agreed upon from time to time between the
Fund and the Custodian.

8.    Responsibility of Custodian
      ---------------------------

      So long as and to the extent that it is in the exercise of reasonable
care, the Custodian shall not be responsible for the title, validity or
genuineness of any property or evidence of title thereto received by it or
delivered by it pursuant to this Contract and shall be held harmless in acting
upon any notice, request, consent, certificate or other instrument reasonably
believed by it to be genuine and to be signed by the proper party or parties,
including any futures commission merchant acting pursuant to the terms of a
three-party futures or options agreement. The Custodian shall be held to the
exercise of reasonable care in carrying out the provisions of this Contract; but
shall be kept indemnified by and shall be without liability to the Fund for any
action taken or omitted by it in good faith without negligence. It shall be
entitled to rely on and may act upon advice of counsel (who may be counsel for
the Fund) on all matters, and shall be without liability for any action
reasonably taken or omitted pursuant to such advice.

      If the Fund requires the Custodian to take any action with respect to
securities, which action involves the payment of money or which action may, in
the opinion of the Custodian, result in the Custodian or its nominee assigned to
the Fund being liable for the payment of money or incurring liability of some
other form, the Fund, as a prerequisite to requiring the Custodian to take such
action, shall provide indemnity to the Custodian in an amount and form
satisfactory to it.



                                      -20-
<PAGE>

     If the Fund requires the Custodian, its affiliates, subsidiaries or agents,
to advance cash or securities for any purpose (including but not limited to
securities settlements, foreign exchange contracts and assumed settlement) or in
the event that the Custodian or its nominee shall incur or be assessed any
taxes, charges, expenses, assessments, claims or liabilities in connection with
the performance of this Contract, except such as may arise from its or its
nominee's own negligent action, negligent failure to act or willful misconduct,
any property at any time held for the account of the Fund shall be security
therefor and should the Fund fail to repay the Custodian promptly, the Custodian
shall be entitled to utilize available cash and to dispose of the Fund assets to
the extent necessary to obtain reimbursement.

9.   Effective Period, Termination and Amendment
     -------------------------------------------

     This Contract shall become effective as of its execution, shall continue in
full force and effect until terminated as hereinafter provided, may be amended
at any time by mutual agreement of the parties hereto and may be terminated by
either party by an instrument in writing delivered or mailed, postage prepaid to
the other party, such termination to take effect not sooner than thirty (30)
days after the date of such delivery or mailing; provided, however that the
                                                 --------
Custodian shall not act under Section 2.10 hereof in the absence of receipt of
an initial certificate of the Secretary or an Assistant Secretary that the Board
of Directors of the Fund has approved the initial use of a particular Securities
System and the receipt of an annual certificate of the Secretary or an Assistant
Secretary that the Board of Directors has reviewed the use by the Fund of such
Securities System, as required in each case by Rule 17f-4 under the Investment
Company Act of 1940, as amended and that the Custodian shall not act under
Section 2.10A hereof in the absence of receipt of an initial certificate of the
Secretary or an Assistant Secretary that the


                                     -21-
<PAGE>

Board of Directors has approved the initial use of the Direct Paper System and
the receipt of an annual certificate of the Secretary or an Assistant Secretary
that the Board of Directors has reviewed the use by the Fund of the Direct Paper
System; provided further, however, that the Fund shall not amend or terminate
        ----------------
this Contract in contravention of any applicable federal or state regulations,
or any provision of the Articles of Incorporation, and further provided, that
the Fund may at any time by action of its Board of Directors (i) substitute
another bank or trust company for the Custodian by giving notice as described
above to the Custodian, or (ii) immediately terminate this Contract in the event
of the appointment of a conservator or receiver for the Custodian by the
Comptroller of the Currency or upon the happening of a like event at the
direction of an appropriate regulatory agency or court of competent
jurisdiction.

     Upon termination of the Contract, the Fund shall pay to the Custodian such
compensation as may be due as of the date of such termination and shall likewise
reimburse the Custodian for its costs, expenses and disbursements.

10.   Successor Custodian
      -------------------

     If a successor custodian shall be appointed by the Board of Directors of
the Fund, the Custodian shall, upon termination, deliver to such successor
custodian at the office of the Custodian, duly endorsed and in the form for
transfer, all securities then held by it hereunder and shall transfer to an
account of the successor custodian all of the Fund's securities held in a
Securities System.

     If no such successor custodian shall be appointed, the Custodian shall, in
like manner, upon receipt of a certified copy of a vote of the Board of
Directors of the Fund, deliver at the



                                     -22-
<PAGE>

office of the Custodian and transfer such securities, funds and other properties
in accordance with such vote.

     In the event that no written order designating a successor custodian or
certified copy of a vote of the Board of Directors shall have been delivered to
the Custodian on or before the date when such termination shall become
effective, then the Custodian shall have the right to deliver to a bank or trust
company, which is a "bank" as defined in the Investment Company Act of 1940,
doing business in Boston, Massachusetts, of its own selection, having an
aggregate capital, surplus, and undivided profits, as shown by its last
published report, of not less than $25,000,000, all securities, funds and other
properties held by the Custodian and all instruments held by the Custodian
relative thereto and all other property held by it under this Contract and to
transfer to an account of such successor custodian all of the Fund's securities
held in any Securities System. Thereafter, such bank or trust company shall be
the successor of the Custodian under this Contract.

     In the event that securities, funds and other properties remain in the
possession of the Custodian after the date of termination hereof owing to
failure of the Fund to procure the certified copy of the vote referred to or of
the Board of Directors to appoint a successor custodian, the Custodian shall be
entitled to fair compensation for its services during such period as the
Custodian retains possession of such securities, funds and other properties and
the provisions of this Contract relating to the duties and obligations of the
Custodian shall remain in full force and effect.

Fund may from time to time agree on such provisions interpretive of or in
addition to the provisions of this Contract as may in their joint opinion be
consistent with the general tenor of this Contract. Any such interpretive or
additional provisions shall be in a writing signed by both parties and shall be
annexed hereto, provided that no such interpretive or additional provisions
                --------
shall contravene any applicable federal or state regulations or any provision of
the Articles of Incorporation of the Fund. No interpretive or additional
provisions made as provided in the preceding sentence shall be deemed to be an
amendment of this Contract.

12.   Massachusetts Law to Apply
      --------------------------

                          MUNIYIELD PENNSYLVANIA FUND


                            TERMS AND CONDITIONS OF
                      AUTOMATIC DIVIDEND REINVESTMENT PLAN


     1.  Appointment of Agent.  You, _________________, will act as Agent for
         --------------------
me, and will open an account for me under the Dividend Reinvestment Plan (the
"Plan") in the same name as my present shares of Beneficial Interest, par value
$.10 per share ("Common Stock"), of MUNIYIELD PENNSYLVANIA FUND (the "Fund") are
registered, and will automatically put into effect for me the dividend
reinvestment option of the Plan as of the first record date for a dividend or
capital gains distribution (collectively referred to herein as a "dividend"),
payable at the election of shareholders in cash or shares of Beneficial
Interest.

     2.  Dividends Payable in Common Shares.  My participation in the Plan
         ----------------------------------
constitutes an election by me to receive dividends in shares of Beneficial
Interest whenever the Fund declares a dividend. In such event, the dividend
amount shall automatically be made payable to me entirely in shares of
Beneficial Interest which shall be acquired by the Agent for my account,
depending upon the circumstances described in paragraph 3, either (i) through
receipt of additional shares of unissued but authorized shares of Beneficial
Interest from the Fund ("newly issued shares") as described in paragraph 6 or
(ii) by purchase of outstanding shares of Beneficial Interest on the open market
("open-market purchases") as described in paragraph 7.

     3.  Determination of Whether Newly-Issued Shares or Open Market Purchases.
         ---------------------------------------------------------------------
If on the payment date for the dividend (the "valuation date"), the net asset
value per share of the Common Shares, as defined in paragraph 8, is equal to or
less than the market price per share of the Common Shares, as defined in
paragraph 8, plus estimated brokerage commissions (such condition being referred
to herein as "market premium"), the Agent shall invest the dividend amount in
newly issued shares on my behalf as described in paragraph 6. If on the
valuation date, the net asset value per share is greater than the market value
(such condition being referred to herein as "market discount"), the Agent shall
invest the dividend amount in shares acquired on my behalf in open-market
purchases as described in paragraph 7.

     4.  Purchase Period for open-Market Purchases.  In the event of a market
         -----------------------------------------
discount on the valuation date, the Agent shall have until the last business day
before the next ex-dividend date with respect to the shares of Beneficial
Interest or in no event more than 30 days after the valuation date (the "last
purchase date") to invest the dividend amount in shares acquired in open-market
purchases except where temporary curtailment or suspension of purchases is
necessary to comply with applicable provisions of federal securities laws.

     5.  Failure to Complete Open-Market Purchases During Purchase Period.  If
         ----------------------------------------------------------------
the Agent is unable to invest the full dividend amount in open-market purchases
during tne purchase period because the market discount has shifted to a market
premium or otherwise, the Agent will invest the uninvested poftion of the
dividend amount in newly issued shares at the close of business on the last
purchase date as described in paragraph 4; except that the Agent may not
<PAGE>

acquire newly issued shares after the valuation date under the foregoing
circumstances unless it has received a legal opinion that registration of such
shares is not required under the Securities Act of 1933 or unless the shares to
be issued are registered under such Act.

     6.  Acquisition of Newly-Issued Shares.  In the event that all or part of
         ----------------------------------
the dividend amount is to be invested in newly issued shares, you shall
automatically receive such newly-issued shares of Beneficial Interest, including
fractions, for my account and the number of additional newly-issued shares of
Beneficial Interest to be credited to my account shall be determined by dividing
the dollar amount of the dividend on my shares to be invested in newly-issued
shares by the net asset value per share of Common Shares on the date the shares
are issued (the valuation date in the case of an initial market premium or the
last purchase date in case the Agent is unable to complete open-market purchases
during the purchase period); provided, that the maximum discount from the then
current market price per share on the date of issuance shall not exceed 5%.

     7.  Manner of Making Open-Market Purchases.  In the event that the dividend
         --------------------------------------
amount is to be invested in shares of Beneficial Interest acquired in open-
market purchases, you shall apply the amount of such dividend on my shares (less
my pro rata share of brokerage commissions incurred with respect to your open-
market purchases) to the purchase on the open-market of shares of the Common
Stock for my account.  Open-market purchases may be made on any securities
exchange where the Common Shares are traded, in the over-the-counter market or
in negotiated transactions and may be on such terms as to price, delivery and
otherwise as you shall determine.  My funds held by you uninvested will not bear
interest, and it is understood that, in any event, you shall have no liability
in connection with any inability to purchase shares within 30 days after the
initial date of such purchase as herein provided, or with the timing of any
purchases affected.  You shall have no responsibility as to the value of the
Common Shares acquired for my account.  For the purposes of cash investments you
may commingle my funds with those of other shareholders of the Fund for whom you
similarly act as Agent, and the average price (including brokerage commissions)
of all shares purchased by you as Agent in the open market shall be the price
per share allocable to me in connection with open-market purchases.

     8.  Meaning of Market Price and Net Asset Value.  For all purposes of the
         -------------------------------------------
Plan: (a) the market price of the Common Shares on a particular date shall be
the last sales price on the Stock Exchange (the "Exchange") on that date, or, if
there is no sale on the Exchange on that date, then the mean between the closing
bid and asked quotations for such stock on the Exchange on such date and (b) net
asset value per share of the Common Shares on a particular date shall be as
determined by or on behalf of the Fund.

     9.  Registration of Shares Acquired Pursuant to the Plan.  You may hold my
         ----------------------------------------------------
shares of Beneficial Interest acquired pursuant to the Plan, together with the
shares of other shareholders of the Fund acquired pursuant to the Plan, in
noncertificated form in your name or that of your nominee.  You will forward to
me any proxy solicitation material and will vote any shares so held for me only
in accordance with the proxy returned by me to the Fund.  Upon my written
request, you will deliver to me, without charge, a certificate or certificates
for the full shares held by you for my account.

                                       2
<PAGE>

     10.  Confirmations.  You will confirm to me each acquisition made for my
          -------------
account as soon as practicable but not later than 60 days after the date
thereof.

     11.  Fractional Interests.  Although I may from time to time have an
          --------------------
undivided fractional interest (computed to three decimal places) in a share of
the Fund, no certificates for a fractional share will be issued.  However,
dividends and distributions on fractional shares will be credited to my account.
In the event of termination of my account under the Plan, you will adjust for
any such undivided fractional interest in cash at the market value of the Fund's
shares at the time of termination less the pro rata expense of any sale required
to make such an adjustment.

     12.  Stock Dividends or Share Purchase Rights.  Any stock dividends or
          ----------------------------------------
split shares distributed by the Fund on shares held by you for me will be
credited to my account.  In the event that the Fund makes available to its
shareholders rights to purchase additional shares or other securities, the
shares held for me under the Plan will be added to other shares held by me in
calculating the number of rights to be issued to me.

     13.  Service Fee.  Your service fee for handling capital gains
          -----------
distributions or income dividends will be paid by the Fund. I will be charged
for my pro rata share of brokerage commissions on all open market purchases.

     14.  Termination of Account.  I may terminate my account under the Plan by
          ----------------------
notifying you in writing. Such termination will be effective immediately if my
notice is received by you not less than ten days prior to any dividend or
distribution record date; otherwise such termination will be effective on the
first trading day after the payment date for such dividend or distribution with
respect to any subseqaent dividend or distribution. The Plan may be terminated
by you or the Fund upon notice in writing mailed to me at least 90 days prior to
any record date for the payment of any dividend or distribution by the Fund.
Upon any termination you will cause a certificate or certificates for the full
shares held for me under the Plan and cash adjustment for any fraction to be

the proceeds to me, you are authorized to deduct brokerage commissions for this
transaction from the proceeds.

     15.  Amendment of Plan.  These terms and conditions may be amended or

or appropriate to comply with applicable law or the rules or policies of the
Securities and Exchange Commission or any other regulatory authority, only by
mailing to me appropriate written notice at least 90 days prior to the effective
date thereof. The amendment or supplement shall be deemed to be accepted by me
unless, prior to the effective date, thereof, you receive written notice of the
termination of my account under the Plan. Any such amendment may include an
appointment by you in your place and stead of a successor Agent under these
terms and conditions, with full power and authority to perform all or any of the
acts to be performed by the Agent under these terms and conditions.  Upon any
such appointment of an Agent for the purpose of receiving dividends and
distributions, the Fund will be authorized to pay to such successor Agent, for
my account, all dividends and distributions payable on Common Shares of the Fund
held in my name or under the Plan for retention or application by such successor
Agent as provided in these terms and conditions.

MuniYield Pennsylvania Fund
800 Scudders Mill Road
Plainsboro, New Jersey  08536

Ladies and Gentlemen:

     We have acted as counsel for MuniYield Pennsylvania Fund (the "Fund") in
connection with the proposed acquisition by the Fund of substantially all of the
assets and the assumption by the Fund of substantially all of the liabilities of
MuniVest Pennsylvania Insured Fund ("MuniVest Pennsylvania") and MuniHoldings
Pennsylvania Insured Fund ("MuniHoldings Pennsylvania"), in exchange for newly-
issued common shares of beneficial interest and auction market preferred shares
of the Fund (collectively the "Reorganization"). This opinion is furnished in
connection with the Fund's Registration Statement on Form N-14 under the
Securities Act of 1933, as amended (File No. 333-88395) (the "Registration
Statement"), relating to common shares of beneficial interest, par value $.10
per share, and auction market preferred shares of the Fund, par value
$0.05 per share (the "Shares"), to be issued in the Reorganization.

     As counsel for the Fund, we are familiar with the proceedings taken by it
and to be taken by it in connection with the authorization, issuance and sale of
the Shares.  In addition, we have examined and are familiar with the Declaration
of Trust of the Fund, as amended, the By-Laws of the Fund, as
amended, and such other documents as we have deemed relevant to the matters
referred to in this opinion.

     Based upon the foregoing, we are of the opinion that subsequent to the
approval of the Agreement and Plan of Reorganization between the Fund, MuniVest
Pennsylvania and

<PAGE>

MuniHoldings Pennsylvania set forth in the joint proxy statement and prospectus
constituting a part of the Registration Statement (the "Proxy Statement and
Prospectus"), the Shares, upon issuance in the manner referred to in the
Registration Statement, for consideration not less than the par value thereof,
will be legally issued, fully paid and non-assessable common shares or auction
market preferred shares, as the case may be, of the Fund (except for certain
possible liability of shareholders described in the Proxy Statement and
Prospectus under "Item 1. The Reorganization - Comparison of the Funds - Capital
Shares").

     In rendering the foregoing opinions, we have relied, without independent
investigation or verification, as to all matters involving the laws of the
Commonwealth of Massachusetts, upon the opinion of Bingham Dana LLP.

     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the use of our name in the Proxy Statement and
Prospectus constituting a part thereof.

                                              Very truly yours,

                                              /s/ Brown & Wood LLP

defense of such claim or to defend against said claim in its own name or in the
name of the Bank. The Bank shall in no case confess any claim or make any
compromise in any case in which the Fund may be required to indemnify the Bank

2.   The Auction.
     ------------

2.1  Purpose; Incorporation by Reference of Auction
     Procedures and Settlement Procedures.
     -------------------------------------

(a)  The Certificate of Designation provides that the Applicable Rate on shares
     of AMPS, for each Dividend Period therefor after the Initial Dividend
     Period shall be the rate per annum that a commercial bank, trust company,
     or other financial institution appointed by the Trust advises results from
     implementation of the Auction Procedures. The Board of Trustees of the
     Trust has adopted a resolution appointing IBJ Schroder Bank & Trust Company
     as Auction Agent for purposes of the Auction Procedures. The Auction Agent
     hereby accepts such appointment and agrees that, on each Auction Date, it
     shall follow the procedures set forth in this Section 2 and the Auction
     Procedures for the purpose of determining the Applicable Rate for the AMPS
     for the next Dividend Period therefor. Each periodic operation of such
     procedures is hereinafter referred to as an "Auction."

(b)  All of the provisions contained in the Auction Procedures and the
     Settlement Procedures are incorporated herein by reference in their
     entirety and shall be deemed to be a part hereof to the same extent as if
     such provisions were fully set forth herein.

2.2  Preparation for Each Auction; Maintenance
     of Registry of Beneficial Owners.
     ---------------------------------

(a)  Pursuant to Section 2.5 hereof, the Trust shall not designate any Person to
     act as a Broker-Dealer without prior written approval of the Auction Agent
     (which approval shall not be withheld unreasonably).  At the time of
     closing of the initial issuance and sale of the AMPS (the "Closing"), the
     Trust shall provide the Auction Agent with a list of the Broker-Dealers
     previously approved by the Auction Agent and shall cause to be delivered to
     the Auction Agent for execution by the Auction Agent a Broker-Dealer
     Agreement signed by each such Broker-Dealer. The Auction Agent shall keep
     such list current and accurate and shall indicate thereon, or on a separate
     list, the identity of each Existing Holder, if any, whose most recent Order
     was submitted by a Broker-Dealer on such list and resulted in such Existing
     Holder continuing to hold or purchasing shares of AMPS. Not later than five
     days prior to any Auction Date for which any change in such list of Broker-
     Dealers is to be effective, the Trust shall notify the Auction Agent in
     writing of such change and, if any such change is the addition of a Broker-
     Dealer to such list, the Trust shall cause to be delivered to the Auction
     Agent for execution by the Auction Agent a Broker-Dealer Agreement signed
     by such Broker-Dealer. The Auction Agent shall have entered into a Broker-
     Dealer Agreement with each Broker-Dealer prior to the participation of any
     such Broker-Dealer in any Auction.

                                       4
<PAGE>

(b)  In the event that the Auction Date for any Auction shall be changed after
     the Auction Agent shall have given the notice referred to in clause (vii)
     of Paragraph (a) of the Settlement Procedures, the Auction Agent, by such
     means as the Auction Agent deems practicable, shall give notice of such
     change to the Broker-Dealers not later than the earlier of 9:15 A.M. on the
     new Auction Date or 9:15 A.M. on the old Auction Date.

(c)  With respect to each Dividend Period that is a Special Dividend Period, the
     Trust may, at its sole option and to the extent permitted by law, by
     telephonic and written notice (a "Request for Special Dividend Period") to
     the Auction Agent and to each Broker-Dealer, request that the next
     succeeding Dividend Period for the AMPS will be a number of days (other
     than seven), evenly divisible by seven, and not fewer than seven nor more
     than 364 in the case of a Short Term Dividend Period or a number of whole
     years not greater than five years in the case of a Long Term Dividend
     Period, specified in such notice, provided that, the Trust may not give a
     Request for Special Dividend Period of greater than 28 days (and any such
     request shall be null and void) unless the Trust has given written notice
     thereof to S&P and received written confirmation from Moody's that such
     action would not impair the rating then assigned to the AMPS by Moody's and
     unless, for any Auction occurring after the Initial Auction, sufficient
     Clearing Bids were made in the last occurring Auction and unless full
     cumulative dividends, any amounts due with respect to mandatory redemptions
     and any Additional Dividends payable prior to such date have been paid in
     full. Such Request for Special Dividend Period, in the case of a Short Term
     Dividend Period, shall be given on or prior to the fourth Business Day but
     not more than seven Business Days prior to an Auction Date for the AMPS
     and, in the case of a Long Term Dividend Period, shall be given on or prior
     to the 14th day but not more than 28 days prior to the Auction Date for the
     AMPS. Upon receiving such Request for Special Dividend Period, the Broker-
     Dealers shall jointly determine whether given the factors set forth in
     paragraph 2(c)(iii) of the Certificate of Designation it is advisable that
     the Trust issue a Notice of Special Dividend Period for the AMPS as
     contemplated by such Request for Special Dividend Period and the Optional
     Redemption Price of the AMPS during such Special Dividend Period and the
     Specific Redemption Provisions and shall give the Trust and the Auction
     Agent written notice (a "Response") of such determination by no later than
     the third Business Day prior to such Auction Date. If the Broker-Dealers
     shall not give the Trust and the Auction Agent a Response by such third
     Business Day or if the Response states that given the factors referred to
     above it is not advisable that the Trust give a Notice of Special Dividend
     Period (as defined below) for the AMPS, the Trust may not give a Notice of
     Special Dividend Period in respect of such Request for Special Dividend
     Period. In the event the Response indicates that it is advisable that the
     Trust give a Notice of Special Dividend Period for the AMPS, the Trust may
     by no later than the second Business Day prior to such Auction Date give a
     notice (a "Notice of Special Dividend Period") to the Auction Agent, the
     Securities Depository and each Broker-Dealer, which notice will specify (i)
     the duration of the Special Dividend Period, (ii) the Optional Redemption
     Price as specified in the related Response and (iii) the Specific
     Redemption Provisions, if any, as specified in the related Response. The
     Trust shall not give a Notice of Special Dividend Period, or, if such
     Notice of Special Dividend Period shall have already been given, shall give
     telephonic and written notice of its revocation (a "Notice of Revocation")
     to the Auction Agent, each Broker-Dealer, and the Securities Depository


                                       5
<PAGE>

     on or prior to the Business Day prior to the relevant Auction Date if (x)
     either the 1940 Act AMPS Coverage is not satisfied or the Trust shall fail
     to maintain S&P Eligible Assets and Moody's Eligible Assets each with an
     aggregate Discounted Value at least equal to the AMPS Basic Maintenance
     Amount in each case on each of the two Valuation Dates immediately
     preceding the Business Day prior to the relevant Auction Date on an actual
     basis and on a pro forma basis giving effect to the proposed Special
     Dividend Period (using as a pro forma dividend rate with respect to such
     Special Dividend Period the dividend rate which the Broker-Dealers shall
     advise the Trust is an approximately equal rate for securities similar to
     the AMPS with an equal dividend period), provided that in calculating the
     aggregate Discounted Value of Moody's Eligible Assets for this purpose, the
     Moody's Exposure Period shall be deemed to be one week longer, (y)
     sufficient funds for the payment of dividends payable on the immediately
     succeeding Dividend Payment Date have not been irrevocably deposited with
     the Auction Agent by the close of business on the third Business Day
     preceding the related Auction Date or (z) the Broker-Dealer(s) jointly
     advise the Trust that after consideration of the factors referred to above
     they have concluded that it is advisable to give a Notice of Revocation. If
     the Trust is prohibited from giving a Notice of Special Dividend Period as
     a result of the factors enumerated in clause (x), (y) or (z) of the
     preceding sentence or if the Trust gives a Notice of Revocation with
     respect to a Notice of Special Dividend Period, the next succeeding
     Dividend Period will be a 7-day Dividend Period. In addition, in the event
     sufficient Clearing Bids are not made in any Auction or an Auction is not
     held for any reason, the next succeeding Dividend Period will be a 7-day
     Dividend Period, and the Trust may not again give a Notice of Special
     Dividend Period (and any such attempted notice shall be null and void)
     until sufficient Clearing Bids have been made in an Auction with respect to
     a 7-day Dividend Period.

(d)  (i) Except as otherwise provided in paragraph 2(f) of the Certificate of
     Designation, whenever the Trust intends to include any net capital gains or
     other income subject to regular Federal income tax in any dividend on
     shares of AMPS, the Trust will notify the Auction Agent of the amount to be
     so included at least five Business Days prior to the Auction Date on which
     the Applicable Rate for such dividend is to be established. Whenever the
     Auction Agent receives such notice from the Trust, it will in turn notify
     each Broker-Dealer, who, on or prior to such Auction Date, in accordance
     with its Broker-Dealer Agreement, will notify its Existing Holders and
     Potential Holders believed to be interested in submitting an order in the
     Auction to be held on such Auction Date. Whenever the Trust includes any
     additional amounts in a dividend as provided in paragraph 2(f) of the
     Certificate of Designation, the Trust will notify the Auction Agent of such
     additional amounts to be so included in such dividend at least five
     Business Days prior to the applicable Dividend Payment Date. Whenever the
     Auction Agent receives such notice from the Trust it will in turn notify
     the Securities Depository and each Broker-Dealer, who, on or prior to the
     applicable Dividend Payment Date, in accordance with its Broker-Dealer
     Agreement, will notify its Existing Holders.

(ii) If the Trust makes a Retroactive Taxable allocation, the Trust will, within
     90 days (and generally within 60 days) after the end of its fiscal year for
     which a Retroactive Taxable Allocation is made provide notice thereof to
     the Auction Agent and to each holder of shares (initially the Securities
     Depository) during such fiscal year at

                                       6
<PAGE>

     such holder's address as the same appears or last appeared on the share
     books of the Trust. The Trust will, within 30 days after such notice is
     given to the Auction Agent, pay to the Auction Agent (who will then
     distribute to such holders of shares of AMPS), out of funds legally
     available therefor, a cash amount equal to the aggregate Additional
     Dividend with respect to all Retroactive Taxable Allocations made to such
     holders during the fiscal year in question.

(e)  (i) On each Auction Date, the Auction Agent shall determine the Reference
     Rate and the Maximum Applicable Rate. If the Reference Rate is not quoted
     on an interest basis but is quoted on a discount basis, the Auction Agent
     shall convert the quoted rate to an Interest Equivalent, as set forth in
     paragraph 1 of the Certificate of Designation; or, if the rate obtained by
     the Auction Agent is not quoted on an interest or discount basis, the
     Auction Agent shall convert the quoted rate to an interest rate after
     consultation with the Trust as to the method of such conversion. Not later
     than 9:30 A.M. on each Auction Date, the Auction Agent shall notify the
     Trust and the Broker-Dealers of the Reference Rate so determined and the
     Maximum Applicable Rate.

(ii) If the Reference Rate is the applicable "AA" Composite Commercial Paper
     Rate and such rate is to be based on rates supplied by Commercial Paper
     Dealers and one or more of the Commercial Paper Dealers shall not provide a
     quotation for the determination of the applicable "AA" Composite Commercial
     Paper Rate, the Auction Agent shall immediately notify the Trust so that
     the Trust can determine whether to select a Substitute Commercial Paper
     Dealer or Substitute Commercial Paper Dealers to provide the quotation or
     quotations not being supplied by any Commercial Paper Dealer or Commercial
     Paper Dealers. The Trust shall promptly advise the Auction Agent of any
     such selection. If the Trust does not select any such Substitute Commercial
     Paper Dealer or Substitute Commercial Paper Dealers, then the rates shall
     be supplied by the remaining Commercial Paper Dealer or Commercial Paper
     Dealers.

(iii) If, after the date of this Agreement, there is any change in the
     prevailing rating of AMPS by either of the rating agencies (or substitute
     or successor rating agencies) referred to in the definition of the Maximum
     Applicable Rate, thereby resulting in any change in the corresponding
     applicable percentage for the AMPS, as set forth in said definition (the
     "Percentage"), the Trust shall notify the Auction Agent in writing of such
     change in the Percentage prior to 9:00 A.M. on the Auction Date for AMPS
     next succeeding such change. The Percentage for the AMPS on the date of
     this Agreement is as specified in paragraph 11(a)(vii) of the Certificate
     of Designation. The Auction Agent shall be entitled to rely on the last
     Percentage of which it has received notice from the Trust (or, in the
     absence of such notice, the Percentage set forth in the preceding sentence)
     in determining the Maximum Applicable Rate as set forth in Section
     2.2(e)(i) hereof.

(f)  (i) The Auction Agent shall maintain a current registry of the beneficial
     owners of the shares of the AMPS who shall constitute the Existing Holders
     for purposes of each Auction. The Trust shall use its best efforts to
     provide or cause to be provided to the Auction Agent within ten days
     following the date of Closing a list of the initial Existing Holders of the
     AMPS, and the Broker-Dealer of each such Existing

                                       7
<PAGE>

     Holder through which such Existing Holder purchased such shares. The
     Auction Agent may rely upon, as evidence of the identities of the Existing
     Holders, such list, the results of each Auction and notices from any
     Existing Holder, the Agent Member of any Existing Holder or the Broker-
     Dealer of any Existing Holder with respect to such Existing Holder's
     transfer of any shares of AMPS to another Person.

(ii) In the event of any partial redemption of any shares of AMPS, upon notice
     by the Trust to the Auction Agent of such partial redemption, the Auction
     Agent shall promptly request the Securities Depository to notify the
     Auction Agent of the identities of the Agent Members (and the respective
     numbers of shares) from the accounts of which shares have been called for
     redemption and the person or department at such Agent Member to contact
     regarding such redemption, and at least two Business Days prior to the .
     Auction preceding the date of redemption with respect to the shares being
     partially redeemed, the Auction Agent shall request each Agent Member so
     identified to disclose to the Auction Agent (upon selection by such Agent
     Member of the Existing Holders whose shares are to be redeemed) the number
     of shares of the AMPS of each such Existing Holder, if any, to be redeemed
     by the Trust; provided the Auction Agent has been furnished with the name
     and telephone number of a person or department at such Agent Member from
     which it is to request such information. If necessary to procure such
     information, the Auction Agent shall deliver to each Agent Member a
     facsimile copy of the Purchaser's Letter of each Existing Holder
     represented by such Agent Member, which authorizes and instructs such Agent
     Member to release such information to the Auction Agent. In the absence of
     receiving any such information with respect to an Existing Holder, from
     such Existing Holder's Agent Member or otherwise, the Auction Agent may
     continue to treat such Existing Holder as the beneficial owner of the
     number of shares of the AMPS shown in the Auction Agent's registry of
     beneficial owners.

(iii) The Auction Agent shall register a transfer of the beneficial ownership of
     shares of the AMPS from an Existing Holder to another Person only if such
     transfer is made to a Person that has delivered a signed Purchaser's Letter
     to the Auction Agent and only if (A) such transfer is pursuant to an
     Auction or (B) if such transfer is made other than pursuant to an Auction,
     the Auction Agent has been notified in writing in a notice substantially in
     the form of Exhibit D to the Broker-Dealer Agreement, by such Existing
     Holder, the Agent Member of such Existing Holder, or the Broker-Dealer of
     such Existing Holder of such transfer. The Auction Agent is not required to
     accept any notice of transfer delivered for an Auction unless it is
     received by the Auction Agent by 3:00 P.M. on the Business Day next
     preceding the applicable Auction Date. The Auction Agent shall rescind a
     transfer made on the registry of the beneficial owners of any shares of
     AMPS if the Auction Agent has been notified in writing in a notice
     substantially in the form of Exhibit E to the Broker-Dealer Agreement by
     the Agent Member or the Broker-Dealer of any Person that (i) purchased any
     shares of AMPS and the seller failed to deliver such shares or (ii) sold
     any shares of AMPS and the purchaser failed to make payment to such Person
     upon delivery to the purchaser of such shares.

                                       8
<PAGE>

(g)  The Auction Agent may request that the Broker-Dealers, as set forth in
     Section 3.2(c) of the Broker-Dealer Agreements, provide the Auction Agent
     with a list of their respective customers that such Broker-Dealers believe
     are Existing Holders of shares of AMPS. The Auction Agent shall keep
     confidential any such information and shall not disclose any such
     information so provided to any Person other than the relevant Broker-Dealer
     and the Trust, provided that the Auction Agent reserves the right to
     disclose any such information if it is advised by its counsel that its
     failure to do so would be unlawful.

2.3  Auction Schedule.
     ----------------

     The Auction Agent shall conduct Auctions in accordance with the schedule
set forth below. Such schedule may be changed by the Auction Agent with the
consent of the Trust, which consent shall not be unreasonably withheld. The
Auction Agent shall give notice of any such change to each Broker-Dealer. Such
notice shall be received prior to the first Auction Date on which any such
change shall be effective.

the cancelled certificates and accompanying documentation. The Trust shall, at
its expense, retain such records for a minimum additional period of four
calendar years from the date of delivery of the records to the Trust and shall

time, for reasonable periodic, special, or other examinations by representatives
of the Securities and Exchange Commission. The Trust shall also undertake to
furnish to the Securities and Exchange commission, upon demand, at either the
principal office or at any regional office, complete, correct and current hard

address of a Holder upon notice by such Holder. In case of any written request
or demand for the inspection of the share register or any other books of the
Trust in the possession of the Paying Agent, the Paying Agent will notify the
Trust and secure instructions as to permitting or refusing such inspection. The
Paying Agent reserves the right, however, to exhibit the share register or other

     paragraph (a) of the Settlement Procedures, the Auction Agent, by such
     means as the Auction Agent deems practicable, shall give notice of such
     change to BD not later than the earlier of 9:15 A.M. on the new Auction

(c)  BD agrees not to sell, assign or dispose of any shares of AMPS to any

<PAGE>

(d)  BD shall submit Orders to the Auction Agent in writing in substantially the
     form attached hereto as Exhibit C. BD shall submit separate Orders to the
     Auction Agent for each Potential Holder or Existing Holder on whose behalf
     BD is submitting an order and shall not net or aggregate the Orders of
     Potential Holders or Existing Holders on whose behalf BD is submitting
     Orders.

(e)  BD shall deliver to the Auction Agent (i) a written notice, substantially
     in the form attached hereto as Exhibit D, of transfers of shares of AMPS,
     made through BD by an Existing Holder to another Person other than pursuant
     to an Auction, and (ii) a written notice, substantially in the form
     attached hereto as Exhibit E, of the failure of shares of AMPS to be
     transferred to or by any Person that purchased or sold shares of AMPS or
     through BD pursuant to an Auction. The Auction Agent is not required to
     accept any notice delivered pursuant to the terms of the foregoing sentence
     with respect to an Auction unless it is received by the Auction Agent by
     3:00 P.M. on the Business Day next preceding the applicable Auction Date.

3.4  Notice of Auction Results.
     ----------------------------

(a)  On each Auction Date, the Auction Agent shall notify BD by telephone as set
     forth in paragraph (a) of the Settlement Procedures. On the Business Day

     has submitted an Order as set forth in paragraph (b) of the Settlement
     Procedures and take such other action as is required of BD pursuant to the

If any Existing Holder selling shares of AMPS in an Auction fails to deliver
such shares, the BD of any Person that was to have purchased shares of AMPS in
such Auction may deliver to such Person, a number of whole shares of such AMPS
that is less than the number of shares that otherwise was to be purchased by
such Person. In such event, the number of shares of AMPS to be so delivered
shall be determined by such BD. Delivery of such lesser number of shares shall
constitute good delivery. Upon the occurrence of any such failure to deliver
shares, such BD shall deliver to the Auction Agent the notice required by
Section 3.3(e)(ii) hereof. Notwithstanding the foregoing terms of this Section
3.4(b), any delivery or non-delivery of shares of AMPS which represents any
departure from the results of an Auction, as determined by the Auction Agent,
shall be of no effect unless and until the Auction Agent shall have been
notified of such delivery or non-delivery in accordance with the terms of
Section 3.3(e) hereof. The Auction Agent shall have no duty or liability with
respect to enforcement of this Section 3.4(b).

Trust an amount equal to: (a) in the case of any Auction Date immediately

of which is the number of days in such Dividend Period (calculated by counting
the first day of such Dividend Period but excluding the last day thereof) and
the denominator of which is 360, times (ii) 1/4 of 1%, times (iii) $50,000,
times (iv) the sum of (A) the aggregate number of AMPS placed by BD in the

the subject of a Submitted Bid of a Potential Holder submitted by BD and were
purchased as a result of such submission plus (B) the aggregate number of AMPS
subject to valid Hold Orders (determined in accordance with Paragraph 11 of the
Certificate of Designation) submitted to the Auction Agent by BD plus (C) the
number of AMPS deemed to be subject to Hold Orders by Existing Holders pursuant
to Paragraph 11 of the Certificate of Designation that were acquired by such
Existing Holders through BD and (b) in the case of any Auction Date immediately
preceding a Special Dividend Period, that amount as mutually agreed upon by the
Trust and BD, based on the selling concession that would be applicable to an
underwriting of fixed or variable rate preferred shares with a similar final
maturity or variable rate dividend period, at the commencement of such Long Term
Dividend Period.

For purposes of subclause (a)(iv)(C) of the foregoing sentence, if any Existing
Holder who acquired shares of AMPS through BD transfers those shares to another
Person other than pursuant to an Auction, then the Broker-Dealer for the shares
so transferred shall continue to be BD, provided, however, that if the transfer

The Depository Trust Company
55 Water Street
New York, New York 10041

Attention:  General Counsel's Office

               Re: MuniYield Pennsylvania Fund Issuance
                   of Auction Market Preferred Shares(R) ["AMPS" (R)]
                   --------------------------------------------------

Ladies and Gentlemen:

     The purpose of this letter is to set forth certain matters relating to the
issuance and sale by MuniYield Pennsylvania Fund, a Massachusetts business trust
(the "Issuer"), of 800 shares of Auction Market Preferred Shares. The shares are
sometimes herein together called the "AMPS." A description of the AMPS and the
related offering are contained in a prospectus, dated November 23, 1992 (the
"Prospectus"). IBJ Schroder Bank & Trust Company, in its capacity as Auction
Agent (as defined in the Prospectus), will act as the transfer agent, registrar,
dividend disbursing agent and redemption agent with respect to the shares of
AMPS. The shares of AMPS are being distributed through The Depository Trust
Company ("DTC") by Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith
Incorporated (the "Underwriter").

     To induce DTC to accept the shares of AMPS as eligible for deposit at DTC
and to act in accordance with its rules (the "DTC Rules") with respect to the
shares of AMPS, the Issuer and the Auction Agent make the following
representations to DTC:

        1.      Prior to the issuance of the shares of AMPS on November 30, 1992
                the Issuer shall cause the Underwriter to deposit with DTC a
                share certificate representing the AMPS, registered in the name
                of DTC's nominee, Cede & Co., which will respectively represent
                the total number of shares of AMPS, and said certificate shall
                remain in DTC's custody.

        2.      The Prospectus describes provisions for the solicitation of
                consents from, and voting by, holders of the shares of AMPS
                under certain circumstances. The Issuer shall establish a record
                date or record dates for such purposes and give DTC notice of
                such record date or dates not less than 15 calendar days in
                advance of such record date or dates to the extent practicable.
<PAGE>

        3.      In the event of a full or partial redemption of outstanding
                shares of AMPS, the Issuer or the Auction Agent shall give DTC
                notice of such event not less than 20 days prior to the
                redemption date.

        4.      In the event of a partial redemption of shares of AMPS
                outstanding, the Issuer or the Auction Agent shall send DTC a
                notice specifying: the number of shares of AMPS to be redeemed
                and the date such notice is to be mailed to shareholders of the
                Issuer or published by the Issuer ("Publication Date"). Such
                notice shall be sent to DTC by a secure means (e.g., legible
                facsimile transmission, registered or certified mail, overnight
                express delivery or hand delivery) in a timely manner designed
                to assure that such notice is in DTC's possession no later than
                the close of business on the Business Day (as defined in the
                Prospectus) before the Publication Date. (The Issuer or the
                Auction Agent sending such notice shall have a method to verify
                subsequently the use of such means and timeliness of the
                notice.) In the event of a partial redemption, the Publication
                Date shall not be less than 20 days prior to the redemption
                date.

        5.      The Prospectus indicates that the dividend rate for the shares
                of AMPS may vary from time to time. Absent other existing
                arrangements with DTC, the Issuer or.the Auction Agent shall
                give DTC notice of each such change in the dividend rate on the
                same day the new rate is determined by telephone to the
                Supervisor of the Dividend Announcement Section at (212) 709-
                1270, and such notice shall be followed by prompt written
                confirmation sent by a secure means as described in paragraph 4
                above to:

                        Manager, Announcements, Dividend Department
                        The Depository Trust Company
                        7 Hanover Square, 22nd Floor
                        New York, New York 10004

        6.      The Prospectus indicates that each purchaser of shares of AMPS
                or its Broker-Dealer will be required to sign a Purchaser's
                Letter (as defined in the Prospectus) that contains provisions
                restricting transfer of the shares of AMPS purchased. The Issuer
                and the Auction Agent acknowledge that as long as Cede & Co. is
                the sole record owner of the shares of AMPS, Cede & Co. shall be
                entitled to all voting rights applicable to the shares of AMPS
                and to receive the full amount of all dividends, Additional
                Dividends, liquidation proceeds and redemption proceeds payable
                with respect to the shares of AMPS. The Issuer and the Auction
                Agent acknowledge that DTC shall treat any DTC Participant
                (defined in the DTC Rules to mean, generally, securities brokers
                and dealers, banks, trust companies, clearing corporations and
                certain other organizations for whom DTC, directly or
                indirectly, holds securities) having shares of AMPS credited to
                its DTC account as entitled to the full benefits of ownership of
                such shares even if the credits of shares of AMPS to the DTC
                account of such DTC Participant result from transfers or
                failures to transfer in violation of the provisions of the
                Purchaser's Letter. Without limiting the generality of the
                preceding sentence, the Issuer and the Auction Agent acknowledge
                that DTC shall

                                       2
<PAGE>

                treat any DTC Participant having shares of AMPS credited to its
                account as entitled to receive dividends, distributions and
                voting rights, if any, in respect of such shares and, subject to
                Section 17 hereof, to receive certificates evidencing such
                shares of AMPS if such certificates are to be issued in
                accordance with the Issuer's Declaration of Trust (as defined in
                the Prospectus). (The treatment by DTC of the effects of the
                crediting by it of shares of AMPS to the accounts of DTC
                Participants described in the preceding two sentences shall not
                affect the rights of the Issuer, participants in Auctions (as
                defined in the Prospectus) relating to the shares of AMPS,
                purchasers, sellers or holders of shares of AMPS against any DTC
                Participant). DTC shall have no responsibility to ascertain that
                any transfer of shares of AMPS is made in accordance with the
                provisions of the Purchaser's Letter.

        7.      The Prospectus indicates that in the event the Issuer
                retroactively allocates any net capital gains or other income
                subject to regular Federal income tax to shares of AMPS without
                having given advance notice thereof to the Auction Agent as
                described in the Prospectus solely by reason of the fact that
                such allocation is made as a result of the redemption of all or
                a portion of the outstanding shares of AMPS or the liquidation
                of the Issuer (the amount of such allocation referred to herein
                as a "Retroactive Taxable Allocation"), the Issuer will, within
                90 days (and generally within 60 days) after the end of the
                Issuer's fiscal year for which a Retroactive Taxable Allocation
                is made, provide notice thereof to the Auction Agent and to each
                holder of shares of AMPS (initially Cede & Co. as nominee of
                DTC) during such fiscal year at such holder's address as the
                same appears or last appeared on the stock books of the Issuer.
                The Issuer will, within 30 days after such notice is given to
                the Auction Agent, pay to the Auction Agent (who will then
                distribute to such holders of AMPS), out of funds legally
                available therefor, an amount equal to the aggregate Additional
                Dividend (as defined in the Prospectus) with respect to all
                Retroactive Taxable Allocations made to such holders during the
                fiscal year in question.

        8.      The Issuer will notify DTC, at least 10 Business Days prior to
                the payment date for any Additional Dividends, of (i) the record
                date for holders of shares of AMPS entitled to receive
                Additional Dividends, (ii) the amount of Additional Dividends
                payable on a per share basis to such holders and (iii) the CUSIP
                numbers set forth on the share certificates representing such
                shares of AMPS.

        9.      The Prospectus indicates that if the Issuer does not give
                advance notice of the amount of capital gains or other income
                subject to regular Federal income tax to be included in a
                dividend on shares of AMPS in the related Auction, the Issuer
                may include such taxable income in a dividend on shares of AMPS
                if it increases the dividend by an additional amount calculated
                as if such income was a Retroactive Taxable Allocation and the
                additional amount was an Additional Dividend. The Issuer or the
                Auction Agent will notify DTC, at least five Business Days prior
                to the applicable Dividend Payment Date, of the amount of such
                additional amount to be included in the dividend on a per share
                basis.

        10.     The Prospectus indicates that in the event a Response (as
                defined in the Prospectus) indicates that it is advisable that
                the Issuer give a Notice of Special Dividend Period (as defined
                in the Prospectus) for the AMPS, the Issuer may by no later than
                the second day prior to such Auction Date give a Notice of
                Special Dividend Period (as defined in the Prospectus) to the
                Auction Agent, DTC and each Broker-Dealer, which notice will
                specify (i) the duration of the Special Dividend Period, (ii)
                the Optional Redemption Price as specified in the Related
                Response and (iii) the specific Redemption Provisions, if any,
                as specified in the related response. The Issuer is required to
                give telephonic and written notice (a "Notice of Revocation") to
                the Auction Agent, each Broker-Dealer, and DTC on or prior to
                the Business Day prior to the relevant Auction Date under the
                circumstances specified in the Prospectus.

        11.     All notices and payment advices sent to DTC shall contain the
                CUSIP numbers set forth on the share certificates representing
                the AMPS.

        12.     Notices to DTC by facsimile transmission shall be sent to (212)
                709-1093 or (212) 709-1094. The Issuer or Auction Agent shall
                call (212) 709-6884 to confirm such receipt of notice. Except as
                provided in paragraph 5 hereof, notices to DTC by any other
                means shall be sent to:

                        Manager, Reorganization Department
                        Reorganization Window
                        The Depository Trust Company
                        7 Hanover Square, 23rd Floor
                        New York, New York 10004

        13.     Dividend payments shall be received by Cede Co., as nominee of
                DTC, or its registered assigns in same-day funds on each payment
                date or the equivalent as agreed between the Issuer or the
                Auction Agent and DTC ("Fed-Funds"). Such payment shall be made
                payable to the order of "Cede & Co." Absent any other agreement
                between the Issuer or the Auction Agent and DTC, such payments
                shall be addressed as- follows:

                        Manager, Cash Receipts, Dividends
                        The Depository Trust Company
                        7 Hanover Square, 24th Floor
                        New York, New York 10004

        14.     Redemption payments shall be made in Fed-Funds in the manner set
                forth in the SDFS Paying Agent Operating Procedures, a copy of
                which has previously been provided to the Auction Agent.

        15.     DTC may direct the Issuer or the Auction Agent to use any other
                telephone number for facsimile transmission, address, or
                department of DTC as the number, address or department to which
                payments of dividends, redemption proceeds or notices may be
                sent.

        16.     In the event of a redemption necessitating a reduction in the
                number of shares of AMPS outstanding, DTC in its discretion may
                (a) request the Issuer to execute and deliver new share
                certificates representing the remaining outstanding shares of
                AMPS or (b) may make appropriate notations on the certificates
                indicating the date and amounts of such reductions. In the case
                of redemption of all of the shares, DTC will surrender the
                certificates to the Auction Agent for cancellation if required.

        17.     In the event the Issuer determines that beneficial owners of the
                shares of AMPS of any series (generally, the Existing Holders as
                defined in the Issuer's Charter) shall be able to obtain
                certificates representing such shares of AMPS (as provided for
                in the Issuer's Charter), the Issuer or the Auction Agent shall
                notify DTC of the availability of share certificates
                representing such shares of AMPS, as the case may be, and shall
                issue, transfer and exchange such certificates as required by
                DTC and others in appropriate amounts.

        18.     DTC may determine to discontinue providing its services as
                securities depository with respect to the shares of AMPS at any
                time by giving reasonable notice to the Issuer and the Auction
                Agent (at which time DTC will confirm with the Auction Agent the
                aggregate amount of the respective shares of AMPS outstanding).
                Under such circumstances the Issuer and the Auction Agent will
                cooperate with DTC in taking appropriate action to provide for a
                substitute or successor securities depository or to make
                available one or more separate certificates evidencing the
                shares of AMPS to any DTC Participant having such shares
                credited to its DTC account.

        19.     The Issuer hereby authorizes DTC to provide to the Auction Agent
                position listings of its DTC Participants with respect to the
                shares of AMPS from time to time at the request of the Auction
                Agent and at DTC's customary fee, and also authorizes DTC, in
                the event of a partial redemption of shares of AMPS, to provide,
                and DTC hereby agrees to provide the Auction Agent, upon
                request, with the names of those DTC Participants whose
                positions in such shares of AMPS have been selected for
                redemption by DTC. DTC agrees to use its best efforts to notify
                the Auction Agent of those DTC Participants whose positions in
                the shares of AMPS have been selected for redemption by DTC. The
                Issuer authorizes the Auction Agent to provide DTC with such
                signatures, exemplars of signatures and authorizations to act as
                may be deemed necessary by DTC to permit DTC to discharge its
                obligations to its DTC Participants and appropriate regulatory
                authorities.

                This authorization, unless revoked by the Issuer, shall continue
                with respect to the shares of AMPS while any such shares are on
                deposit at DTC, until and unless the Auction Agent shall no
                longer be acting. In such event, the Issuer shall provide DTC
                with similar evidence of the authorization of any successor
                thereto so to act.

        20.     Nothing herein shall be deemed to require the Auction Agent to
                advance funds on behalf of the Issuer.

        21.     A copy of the Agreement and Declaration of Trust of the Issuer
                is on file with the Secretary of State of The Commonwealth of
                Massachusetts and notice is hereby given that this letter has

                Issuer as an officer and not individually and the obligations of
                the Issuer arising out of this letter are not binding upon any
