INVESTMENT 
OBJECTIVE & 
POLICIES            Vanguard Pennsylvania Tax-Free Fund (the "Fund") is an
                    open-end non- diversified investment company that seeks to
                    provide income that is exempt from federal and Pennsylvania
                    personal income taxes. The Fund will invest primarily in
                    securities issued by Pennsylvania state and local
                    governments and public financing authorities, but may also
                    invest in securities of issuers other than Pennsylvania and
                    its political subdivisions. The Fund consists of a Money
                    Market Portfolio and an Insured Long-Term Portfolio, each
                    with distinct investment objectives and policies. The
                    Portfolios are available only to Pennsylvania residents. The
                    Money Market Portfolio seeks to maintain, but does not
                    guarantee, a constant net asset value of $1.00 per share.
                    Although the Money Market Portfolio invests in high-quality
                    instruments, an investment in the Portfolio is neither
                    insured nor guaranteed by any agency of the U.S. Government,
                    including the FDIC.

                    p.m. (Eastern time). The minimum initial investment is
                    $3,000 for each Portfolio or $1,000 for Uniform
                    Gifts/Transfers to Minors Act accounts. The Fund is offered
                    on a no-load basis (i.e., there are no sales commissions or
                    12b-1 fees). However, the Fund incurs expenses for
                    investment advisory, management, administrative, and
                    distribution services.

YIELD AND 
TOTAL RETURN        From time to time a Portfolio of the Fund may advertise its
                    yield and total return. Both yield and total return figures
                    are based on historical earnings and are not intended to
                    indicate future performance. The "total return" of a
                    Portfolio refers to the average annual compounded rates of
                    return over one-, five- and ten-year periods or over the
                    life of a Portfolio (as stated in the advertisement) that
                    would equal an initial amount invested at the beginning of a
                    stated period to the ending redeemable value of the
                    investment, assuming the reinvestment of all dividend and
                    capital gains distributions.

                    In accordance with industry guidelines set forth by the U.S.
                    Securities and Exchange Commission, the "30-day yield" of
                    the Insured Long-Term Portfolio is calculated by dividing
                    the net investment income per share earned during a 30-day
                    period by the net asset value per share on the last day of
                    the period. Net investment income includes interest and
                    dividend income earned on the Portfolio's securities; it is
                    net of all expenses and all recurring and nonrecurring
                    charges that have been applied to all shareholder accounts.
                    The yield calculation assumes that the net investment income
                    earned over 30 days is compounded monthly for six months and
                    then annualized.

                    The "seven-day" or "current" yield of the Money Market
                    Portfolio reflects the income earned by a hypothetical
                    account in the Portfolio during a seven-day period,
                    expressed as an annual percentage rate. The "effective
                    yield" of the Money Market Portfolio assumes the income over
                    the seven-day period is reinvested weekly, resulting in a
                    slightly higher stated yield through compounding.


                    Methods used to calculate advertised yields are standardized
                    for money market and bond funds. However, these methods
                    differ from the accounting methods used by the Portfolios to
                    maintain their books and records, and so advertised yields
                    may not fully reflect the income paid to an investor's
                    account or the yield reported in the Fund's Annual Report to
                    Shareholders.

                      guaranteed by the U.S. Government.                        
                                                                           
                                                                              
                    o The objective of the Pennsylvania Insured Long-Term  
                      Portfolio is to provide investors with a high level of
                      income that is exempt from federal and Pennsylvania  
                      personal income taxes.                                    
                                                                            
                    The two Portfolios of the Fund are available only to  
                    investors who reside in Pennsylvania. There is no assurance
                    that either Portfolio of the Fund will achieve its stated 
                    objective.

                    The investment objective of each Portfolio is fundamental
                    and so may not be changed without the approval of a majority
                    of the Fund's shareholders.

INVESTMENT 
POLICIES            Each Portfolio of the Fund will invest at least 80% of its
                    net assets in Pennsylvania municipal securities, exclusive
                    of Pennsylvania AMT bonds (see Page 6). Pennsylvania
                    municipal securities are debt obligations issued by
                    Pennsylvania state and local governments and public
                    financing authorities (and debt obligations issued by
                    certain U.S. territories) that seek to provide interest
                    income that is exempt from both federal and Pennsylvania
                    personal income taxes. The Pennsylvania municipal securities
                    described above may include securities in which the
                    tax-exempt interest rate is determined by an index, swap or
                    some other formula. Although both invest primarily in
                    Pennsylvania municipal obligations, the two Portfolios
                    differ in terms of credit quality and maturity standards.

Portfolio will invest
in short-term
Pennsylvania
municipal 
securities          Under normal circumstances, the Pennsylvania Money Market   
                    Portfolio will invest at least 80% of its net assets in the 
                    following high quality, short-term Pennsylvania municipal   
                    securities:

                    o Municipal notes and variable rate demand instruments,
                      including derivative securities, rated MIG-1 or VMIG-1, or
                      P-1 by Moody's Investors Service, Inc. ("Moody's") or
                      SP-1+, SP-1, A-1+, or A-1 by Standard & Poor's Corporation
                      ("Standard & Poor's");
                                                           
                    o Tax-exempt commercial paper rated P-1 by ("Standard &     
                      Poor's"); Moody's or A-1+ or A-1 by Standard & Poor's;    
                                                                                
                                                                             
                    o Municipal bonds, including derivative Poor's; securities, 
                      with an effective maturity of 13 months or less rated a   
                      minimum of Aa by Moody's or AA by Standard & Poor's; and  
                                                                            
                                                                                
                    o Unrated municipal notes considered by the and Board of    
                      Trustees to be comparable in credit quality to securities 
                      rated MIG-1 by Moody's or SP-1+ or SP-1 by Standard &     
                      Poor's                                                    
                                                                             
                    In addition, up to 10% of the Pennsylvania Poor's. Money    
                    Market Portfolio's net assets may be invested in            
                    "restricted" money market securities, which are not freely  
                    marketable or which are subject to restrictions on          
                    disposition under the Securities Act of 1933.

                    In seeking to provide a stable share price of $1.00, the
                    Pennsylvania Money Market Portfolio is expected to maintain
                    an average weighted maturity of 90 days or less, and will
                    purchase securities with an effective maturity of 13 months
                    or less and that are eligible for purchase under Rule 2a-7
                    of the Investment Company Act of 1940 (the "1940 Act").
                                                                            
                                                                                
                    Normally, the Pennsylvania Money Market Portfolio will seek 
                    to invest substantially all of its assets in the short-term 
                    Pennsylvania municipal obligations listed above. However,   
                    under certain circumstances, such as a temporary decline in 
                    the issuance of Pennsylvania obligations, the Portfolio may 
                    invest up to 20% of its assets in the following: short-term 
                    municipal securities issued outside of Pennsylvania (the    
                                                                                
                    
                                                                               5

                    income from which may be subject to Pennsylvania income
                    taxes) or certain taxable fixed-income securities (the
                    income from which may be subject to federal and Pennsylvania
                    income taxes).


                    Subject to the same 20% limit, the Portfolio is also
                    authorized to invest in short- term Pennsylvania AMT bonds.
                    The income from Pennsylvania AMT bonds is exempt from
                    regular federal and Pennsylvania income taxes, but may be a
                    tax preference item for purposes of the federal AMT. See
                    "Implementation of Policies" for more information.


                    Under unusual circumstances, such as a national financial
                    emergency, the Portfolio reserves the right to invest more
                    than 20% of its assets in securities other than Pennsylvania
                    municipal obligations. In most instances, however, the
                    Pennsylvania Money Market Portfolio will seek to avoid such
                    holdings in an effort to provide income that is fully exempt
                    from federal and Pennsylvania personal income taxes.

The Insured Long 
Term Portfolio
invests in insured
Pennsylvania
municipal 
securities          Under normal circumstances, the Pennsylvania Insured
                    Long-Term Portfolio will invest at least 80% of its net
                    assets in insured Pennsylvania municipal securities.

                    Insured municipal bonds are those in which scheduled
                    payments of interest and principal are guaranteed by a
                    private (non-governmental) insurance company. The insurance
                    feature does not guarantee the market value of the municipal
                    bonds or the value of the shares of the Pennsylvania Insured
                    Long- Term Portfolio. The insurance refers to the face or
                    par value of the securities in the Portfolio, not the market
                    values of those securities or the share price of the
                    Portfolio. See "Implementation of Policies" for a
                    description of the insurance feature of the Pennsylvania
                    Insured Long-Term Portfolio.

                    The Pennsylvania Insured Long-Term Portfolio is expected to
                    maintain a dollarweighted average maturity between 15 and 25
                    years. Bonds with longer maturities usually offer higher
                    yields, but are also subject to greater market fluctuations
                    as interest rates change. See "Investment Risks."

                    Normally, the Pennsylvania Insured Long-Term Portfolio seeks
                    to invest substantially all of its assets in insured
                    Pennsylvania municipal obligations. However, under certain
                    circumstances, the Portfolio may invest up to 20% of its
                    assets in any combination of the following securities:

                    o Uninsured, long-term Pennsylvania municipal securities
                      rated a minimum of Aa by Moody's or AA by Standard & 
                      Poor's;
           
                    o Uninsured, short-term municipal securities, issued in
                      Pennsylvania or in other states, with the same quality
                      standards that apply for the Pennsylvania Money Market
                      Portfolio;
           
                    o Certain taxable fixed-income securities, including U.S. 
                      Government securities; and 
                                 
                    o Certain tax-exempt municipal securities issued by other
                      states that have similar characteristics to the securities
                      typically purchased by the Portfolio.

                    In such cases, a portion of the Portfolio's income may be
                    subject to Pennsylvania income taxes, federal income taxes,
                    or both. (See page  ).

                    Subject to the same 20% limit, the Portfolio is also        
                    authorized to invest in Pennsylvania AMT bonds. The income
                    from Pennsylvania AMT bonds is exempt from federal and
                    Pennsylvania income taxes, but may be a tax preference item
                    for purposes of the federal alternative minimum tax. See
                    "Implementation of Policies" for more information.

                    Under unusual circumstances, such as a national financial
                    emergency, the Portfolio reserves the right to invest more
                    than 20% of its assets in securities other than Pennsylvania
                    municipal obligations. In most instances, however, the
                    Pennsylvania Insured Long-Term Portfolio will seek to avoid
                    such holdings in an effort to provide income that is fully
                    exempt from federal and Pennsylvania personal income taxes.

Each Portfolio 
will iversify 
its holdings        Although the Fund is organized as a non-diversified
                    investment company, each Portfolio of the Fund intends to
                    diversify its holdings of Pennsylvania municipal securities
                    by complying with Subchapter M of the Internal Revenue Code
                    (the "Code"). In part, Subchapter M requires that, at the
                    close of each quarter of the taxable year, those issuers
                    which represent more than 5% of each Portfolio's assets be
                    limited in aggregate to 50% of each Portfolio, and that no
                    one issuer exceeds 25% of a Portfolio's total assets. As of
                    November 30, 1995, the Pennsylvania Money Market Portfolio
                    held securities of 44 issuers, with the largest holding
                    representing 6.3% of the Portfolio's assets; the
                    Pennsylvania Insured Long- Term Portfolio held securities of
                    114 issuers, with the largest holding representing 2.7% of
                    the Portfolio's assets.

                    The Fund's policy of investing at least 80% of its assets in
                    Pennsylvania municipal securities under normal circumstances
                    is fundamental and may not be changed without shareholder
                    approval.

                    The Fund is responsible for voting the shares of all
                    securities it holds.

                    The investment policies described above are not fundamental
                    and so may be changed by the Board of Trustees without
                    shareholder approval.

INVESTMENT 
RISKS               As mutual funds investing in municipal securities, both     
                    Portfolios of the Fund are subject to interest rate, credit,
The Fund is subject call, income and manager risk. However, the risk            
to interest rate,   characteristics of the two Portfolios vary because of       
credit, call,       differing maturity and credit quality standards.            
income and manager                                                              
risk                Interest rate risk is the potential for fluctuations in the 
                    price of a Portfolio's investments due to changes in        
                    interest rates. In general, bond prices vary inversely with 
                    interest rates. If interest rates rise, bond prices         
                    generally decline; if interest rates fall, bond prices      
                    generally rise. In addition, for a given change in interest 
                    rates, longer-maturity bonds exhibit greater price          
                    fluctuations than shorter-maturity bonds. To compensate     
                    investors for this risk, longer-maturity bonds generally    
                    offer higher yields than shorter-maturity bonds, other      
                                                                                
                    
                    
                                                                               7

                    factors, including credit quality, being equal. Interest
                    rate risk may be increased or decreased when a portfolio
                    purchases derivative Pennsylvania municipal securities. Such
                    derivative securities rely on sophisticated interest rate
                    calculation mechanisms. For certain types of derivative
                    bonds, the magnitude of increases and decreases in their
                    price may be proportionately larger or smaller than, or
                    inverse to, the price changes that broad market interest
                    rate fluctuations would produce in long-term bonds.


                    Credit risk is the possibility that a bond issuer will fail
                    to make timely payments of interest or principal to a
                    Portfolio. The credit risk of a Portfolio depends on the
                    credit quality of its underlying securities. In general, the
                    lower the credit quality of a Portfolio's municipal
                    securities, the higher a Portfolio's yield, all other
                    factors, such as maturity, being equal.

                    Call risk is the possibility that, during periods of falling
                    interest rates, a municipal security with a high stated
                    interest rate will be prepaid (or "called") prior to its
                    expected maturity date. As a result, a Portfolio will be
                    required to invest the unanticipated proceeds at lower
                    interest rates, and the Portfolio's income may decline. Call
                    provisions are most common for intermediate- and long-term
                    municipal bonds.

                    Income risk is the potential for a decline in a Portfolio's
                    income due to falling market interest rates. Because a
                    Portfolio's income is based on interest rates, which can
                    fluctuate substantially over short periods, income risk is
                    expected to vary from Portfolio to Portfolio

The Fund is subject 
to manager risk     Finally, the investment adviser manages the Fund's
                    Portfolios according to the traditional methods of "active"
                    investment management, which involve the buying and selling
                    of securities based upon economic, financial and market
                    analysis and investment judgment. Manager risk refers to the
                    possibility that the Fund's investment adviser may fail to
                    execute a Portfolio's investment strategy effectively. As a
                    result, a Portfolio may fail to achieve its stated
                    objective.


                    Given the Portfolio's stated objectives and policies,
                    interest rate risk for the Pennsylvania Money Market
                    Portfolio is expected to be negligible. The Money Market
                    Portfolio is expected to maintain a stable share price of
                    $1.00. In contrast, interest rate risk for the Pennsylvania
                    Insured Long-Term Portfolio may be high. The average
                    weighted maturity of the Insured Long-Term Portfolio will
                    generally exceed 15 years, meaning that the Portfolio's
                    share price will fluctuate, sometimes substantially, when
                    interest rates change.
   
                    The following chart illustrates the potential interest rate
                    risk of the Pennsylvania Insured Long-Term Portfolio. The
                    chart shows the market value of a $1,000 investment in a
                    single bond with the same yield and maturity characteristics
                    as the Insured Long-Term Portfolio on December 29, 1995,
                    assuming a 1% and 2% point increase or decrease in interest

                    This chart is intended to provide you with general
                    guidelines for evaluating the effect of interest rate
                    changes on the Pennsylvania Insured Long-Term Portfolio and
                    determining the degree of interest rate risk you may be
                    willing to assume. The yields and price changes shown are
                    purely for illustrative purposes, and should not be taken as
                    representative of current or future yields or expected
                    changes in the share price of the Pennsylvania Insured
                    Long-Term Portfolio.

Credit risk is
expected to be
low                 Credit risk depends on the average quality of a Portfolio's
                    underlying securities and its degree of diversification. The
                    Pennsylvania Money Market Portfolio invests primarily in
                    high-quality, short-term Pennsylvania municipal securities,
                    and the Pennsylvania Insured Long-Term Portfolio invests
                    primarily in bonds insured by top-rated insurance companies
                    against the possible default of an issuer as to the timely
                    payment of interest and principal. As a result, the average
                    credit quality of each Portfolio is expected to be very
                    high, and credit risk is expected to be minimal.

                    Ordinarily, an investment company concentrating its
                    investments in one state, such as the Fund, would be exposed
                    to greater credit risks than an investment company investing
                    in a nationally diversified portfolio of municipal
                    securities. These risks include possible tax law changes, a
                    deterioration in economic conditions, and differing levels
                    of supply and demand for Pennsylvania municipal obligations.

                    To minimize the effects of concentrating its investments in
                    Pennsylvania obligations, each Portfolio of the Fund intends
                    to diversify its holdings by complying with Subchapter M of
                    the Code. (See "Investment Policies" for a description of
                    the requirements of Subchapter M.) In addition, the
                    high-quality instruments held by the Pennsylvania Money
                    Market Portfolio and the use of municipal bond insurance in
                    the Pennsylvania Insured Long-Term Portfolio should minimize
                    the credit risk associated with the Fund.

                    As of November 30, 1995, the top ten portfolio holdings,
                    based on market value, represented 54.2% of the Money Market
                    Portfolio's net assets and 18.7% of the Insured Long-Term
                    Portfolio's net assets.

                    and call risks for the Fund's Portfolios:

WHO SHOULD
INVEST              The Fund is intended for Pennsylvania residents seeking    
                    income that is exempt from federal and Pennsylvania personal
Pennsylvania        income taxes. As a rule, tax-free income is attractive to   
residents seeking   investors in high federal tax brackets. You can determine   
tax-exempt income   whether tax-exempt or taxable income is more attractive in  
                    your own case by comparing a Portfolio's tax-free yield with
                    the yield from a comparable taxable mutual fund investment. 
                    See "How to Compare Tax-Free and Taxable Yields".           
                                                                                
                    Assuming that tax-free income is attractive in your own tax 
                    bracket, you should base your selection of a Portfolio (or  
                    Portfolios) on its expected price volatility and yield, and 
                    your own investment objectives, risk preferences and time   
                    horizon.                                                    
                                                                                
                    The Pennsylvania Money Market Portfolio is intended for     
                    investors who are seeking a stable share price and minimal  
                    credit risk. The yield on the Portfolio is expected to      
                    fluctuate from day to day and to be lower on average than   
                    the yield from the Pennsylvania Insured Long-Term Portfolio.
                    The Pennsylvania Money Market Portfolio is suitable as a    
                    short-term investment vehicle, emphasizing maximum          
                    protection of principal.                                    
                                                                                
                    In contrast, the Pennsylvania Insured Long-Term Portfolio is
                    intended for investors who are seeking the highest, most    
                    durable streams of income and who can tolerate sometimes    
                    sharp fluctuations in share price in pursuit of their income
                    objectives. The yield of the Portfolio is expected to be    
                    higher, and the level of income provided more stable, than  
                    that of the Pennsylvania Money Market Portfolio. However,   
                    because of the potential volatility of the Portfolio's share
                    price, the Pennsylvania Insured Long-Term Portfolio is      
                    appropriate only for those investors who can hold their     
                    investment over the long term.                              
                 
                    The Fund is intended to be a long-term investment vehicle
                    and is not designed to provide investors with a means of
                    speculating on short-term market movement. Investors who
                    engage in an excessive amount of account activity generate
                    additional costs that are borne by all of the Fund's
                    shareholders. In order to minimize such costs, the Fund has
                    adopted the following policies. The Fund reserves the right
                    to reject any purchase request (including exchange purchases
                    from other Vanguard portfolios) that is reasonably deemed to
                    be disruptive to efficient portfolio management either
                    because of the timing of the investment or previous
                    excessive trading by the investor. Additionally, the Fund
                    has adopted exchange privilege limitations as described in
                    the section "Exchange Privilege Limitations." Finally, the
                    Fund reserves the right to suspend the offering of its
                    shares.

HOW TO COMPARE 
TAX-FREE AND 
TAXABLE YIELDS      Before choosing a specific tax-exempt investment, such as a
                    Portfolio of the Fund, you should determine if you would be
                    better off with taxable or tax-exempt income in your tax
                    bracket. To compare taxable and tax-free income, you should
                    first determine your combined federal, state and local tax
                    bracket. Then you should calculate the "taxable equivalent
                    yield" for the Portfolio you are considering, and compare it
                    with the yield of a taxable investment with similar credit
                    and maturity characteristics.

                    1. Determine your combined tax bracket. Your combined tax
                    bracket depends on whether you itemize state and local taxes
                    as a deduction on your federal return. If you do not
                    itemize, then your combined tax bracket is the sum of your
                    federal, state and local tax brackets.

                    If you do itemize, then your combined tax bracket is
                    calculated as follows. First, calculate your effective state
                    and local tax bracket using the following formula:


                    (         Federal )                          Effective 
                    ( 100%  -   Tax   ) X    State &              State & 
                    (         Bracket )      Local Bracket  =  Local Bracket 

                    For example, if you are in a 2.8% state and local tax
                    bracket and a 28% federal tax bracket, your effective state
                    and local tax bracket would be 2.0%:
                                  
                                 (100% - 28%)    X    2.8%   =   2.0%

                    Second, add your effective state and local tax bracket to
                    your federal tax bracket to determine your combined tax
                    bracket:

                       Federal             Effective              Combined 
                         Tax       +        State &        =        Tax 
                       Bracket           Local Bracket            Bracket
 
                         28%       +         2.0%          =        30%

                    2. Calculate your taxable equivalent yield. The taxable
                    equivalent yield for a Portfolio is based upon the
                    Portfolio's current tax-exempt yield and your combined tax
                    bracket. The formula is:
                                           
                         Portfolio's Tax-Free Yield 
                      ---------------------------------  =    Your Taxable 
                      100% - Your Combined Tax Bracket      Equivalent Yield

                    For example, if you are in a combined tax bracket of 30%,
                    and a Portfolio's tax- free yield is 6%, the Portfolio's
                    taxable equivalent yield would be 8.6%:
                                                      
                                          6% 
                                     ----------     =    8.6%
                                     100% - 30% 
                                
                    In this example, you would choose the tax-free investment if
                    the 8.6% taxable equivalent yield were greater than the
                    taxable yield from a comparable investment (e.g., a taxable
                    bond fund of comparable maturity and credit quality).

IMPLEMENTATION 
OF POLICIES         The Fund's adviser uses a variety of investment vehicles to 
                    achieve the objective of the Fund. Each Portfolio of the    
                    Fund invests principally in tax-exempt Pennsylvania         
The Fund invests    municipal securities, which are debt obligations issued by  
in municipal        Pennsylvania state and local governments and public         
bonds, notes and    financing authorities (and by certain U.S. territories) that
securities derived  provide interest income that is exempt from federal and     
from municipal      Pennsylvania personal income taxes. Municipal securities    
bonds and notes     include both municipal bonds (those securities              
                                                                                
                    
                    
                    
                    
                    
                    
                    

                                                                              11
<PAGE>



                    with maturities of five years or more) municipal notes
                    (those securities with maturities of less than five years)
                    and derivative securities (those securities in which a
                    maturity may have been shortened by a demand feature).

                    Municipal bonds are issued for a wide variety of reasons: to
                    construct public facilities, such as airports, highways,
                    bridges, schools, hospitals, housing, mass transportation,
                    streets, water and sewer works; to obtain funds for
                    operating expenses; to refund outstanding municipal
                    obligations; and to loan funds to various public
                    institutions and facilities. Certain industrial development
                    bonds are also considered municipal bonds if their interest
                    is exempt from federal income tax. Industrial development
                    bonds are issued by or on behalf of public authorities to
                    obtain funds for privately-operated manufacturing
                    facilities, housing, sports arenas, convention centers,
                    airports, mass transportation systems, and water, gas or
                    sewage works.


                    General obligation municipal bonds are secured by the
                    issuer's pledge of full faith, credit and taxing power.
                    Revenue or special tax bonds are payable from the revenues
                    derived from a particular facility or, in some cases, from a
                    special excise or other tax, but not from general tax
                    revenue. Industrial development bonds are ordinarily
                    dependent on the credit quality of a private company.


                    Municipal notes are issued to meet the short-term funding
                    requirements of local, regional and state governments.
                    Municipal notes include tax anticipation notes, bond
                    anticipation notes, revenue anticipation notes, tax and
                    revenue anticipation notes, construction loan notes,
                    short-term discount notes, tax-exempt commercial paper,
                    demand notes, and similar instruments. Demand notes permit
                    an investor (such as the Fund) to demand from the issuer
                    payment of principal plus accrued interest upon a specified
                    number of days' notice.


The Fund may invest 
in AMT bonds        Each Portfolio of the Fund is authorized to invest up to 20%
                    of its assets in so-called "AMT" bonds. AMT bonds are
                    tax-exempt "private activity" bonds issued after August 7,
                    1986, whose proceeds are directed at least in part to a
                    private, for-profit organization. While the income from AMT
                    bonds is exempt from regular federal income tax, it is a tax
                    preference item for purposes of the federal AMT. The
                    alternative minimum tax is a special separate tax that
                    applies to a limited number of taxpayers who have certain
                    adjustments to income or tax preference items.



The Fund may invest
in Market Discount
bonds               The Fund may invest in "Market Discount" bonds when, in the
                    opinion of the Fund's adviser, the investment will be
                    advantageous to the Fund's shareholders. A Market Discount
                    bond is a bond purchased at a discount from its original
                    issue price after April 30, 1993 and with a maturity in
                    excess of one year from its issue date. In certain
                    circumstances, disposition of a Market Discount bond will
                    result in taxable ordinary income to the extent of any gain
                    realized.

                    Although the objective of the Fund is to provide income free
                    of federal income tax, certain market conditions may make
                    Market Discount bonds desirable investments. The Fund will
                    purchase Market Discount bonds only if the Fund's adviser
                    expects that the purchase of these investments on an
                    after-tax basis will enhance the Fund's total return.

Three types of
insurance may be
used in the Insured
Long-Term 
Portfolio           To provide an added level of credit protection, the
                    Pennsylvania Insured Long- Term Portfolio uses three types
                    of insurance: new issue, mutual fund and secondary market
                    insurance. A new issue insurance policy is purchased by a
                    bond issuer who wishes to increase the credit rating of a
                    security. By paying a premium and meeting the insurer's
                    underwriting standards, the bond issuer is able to obtain a
                    high credit rating for the security (usually Aaa from
                    Moody's or AAA from Standard & Poor's). New issue insurance
                    policies are non-cancellable and continue in force as long
                    as the bonds are outstanding.

                    A mutual fund insurance policy may be used to guarantee
                    specific bonds only while owned by a mutual fund. The
                    Insured Long-Term Portfolio of the Fund has obtained a
                    mutual fund insurance policy from Financial Guaranty
                    Insurance Company ("Financial Guaranty"), a AAA-rated
                    insurance company. Based upon the expected composition of
                    the Portfolio, the annual premiums for the policy are likely
                    to range from 0.20% to 0.40% of the principal value of the
                    bonds insured under the policy, thereby reducing the
                    Portfolio's current yield.

                    A secondary market insurance policy is purchased by an
                    investor (such as the Insured Long-Term Portfolio)
                    subsequent to the bond's original issuance and generally
                    insures a particular bond for the remainder of its term. The
                    Portfolio may purchase bonds that have already been insured
                    under a secondary market insurance policy by a prior
                    investor, or the Portfolio may itself purchase such a policy
                    from Financial Guaranty for bonds that are currently
                    uninsured.
                                
                    An insured municipal bond in the Portfolio will typically be
                    covered by only one of the three policies. For instance, if
                    a bond is already covered by a new issue insurance policy or
                    a secondary market insurance policy, then that security will
                    not be insured under the Portfolio's mutual fund insurance
                    policy. All of the insurance policies used by the Portfolio
                    will be obtained only from insurance companies rated Aaa by
                    Moody's or AAA by Standard & Poor's at the time the
                    insurance contract was obtained. The purchase of insurance
                    from such companies will have the effect of making the
                    insured bonds equivalent in quality to AAA-rated bonds. 

The Insured Long-
Term Portfolio may
report an effective
average weighted
maturity            Each Portfolio of the Fund observes strict maturity
                    guidelines as set forth in detail under "Investment
                    Policies." These maturity standards are specified in terms
                    of a Portfolio's average weighted maturity. From time to
                    time, however, the Fund may also report an effective average
                    weighted maturity for the Insured Long-Term Portfolio, which
                    reflects, among other items, the likelihood that a municipal
                    bond or note held by the Portfolio may be redeemed or
                    "called" prior to its stated maturity date. For example, if
                    the Portfolio consists entirely of 20-year bonds, some of
                    which may be "called" prior to their stated maturity in 20
                    years, the Portfolio's average weighted maturity will be 20
                    years, while its effective average maturity will be shorter.

                                                                              13
<PAGE>

                    A Portfolio's effective average weighted maturity will be
                    influenced by bond market conditions, and so may vary from
                    day to day, even if no change has been made to the
                    Portfolio's underlying investment securities. For example,
                    if interest rates decline, a greater proportion of a
                    Portfolio's securities may be subject to call (redemption)
                    prior to their stated maturity. As a result, reflecting this
                    increased call risk, the effective average maturity of the
                    Portfolio will shorten, independent of actual purchases or
                    sales of portfolio securities.
   
Temporary
Investments         Except as described on pages 5 and 6, each Portfolio will
                    not invest in securities other than municipal bonds, except
                    that each Portfolio may make temporary investments for
                    defensive purposes in (a) notes issued by or on behalf of
                    municipal or corporate issuers, obligations of the U.S.
                    Government and its agencies, commercial paper and bank
                    certificates of deposits; (b) investment companies investing
                    in such securities which have investment objectives
                    consistent with those of the Portfolio to the extent
                    permitted by the Investment Company Act of 1940; and (c) any
                    such securities or municipal bonds subject to repurchase
                    agreements.
    
The Fund may
purchase
when-issued
securities          Each Portfolio may purchase tax-exempt securities on a
                    "when-issued" basis. In buying "when-issued" securities, a
                    Portfolio commits to buy securities at a certain price even
                    though the securities may not be delivered for a certain
                    period. The Portfolio pays for the securities and begins
                    earning interest when the securities are actually delivered.
                    As a consequence, it is possible that the market price of
                    the securities at the time of delivery may be higher or
                    lower than the purchase price.

The Fund may lend
its securities      Each Portfolio may lend its investment securities on either
                    a short-term or long- term basis to qualified institutional
                    investors for the purpose of realizing additional net
                    investment income. Loans of securities by a Portfolio will
                    be collateralized by cash, letters of credit, or securities
                    issued or guaranteed by the U.S. Government or its agencies.
                    The collateral will equal at least 100% of the current
                    market value of the loaned securities. Income derived from
                    the lending of securities is not tax- exempt, and a portion
                    of the tax-exempt interest earned when a municipal security
                    is on loan must be characterized as taxable income.
                    Therefore, each Portfolio will limit such activity in
                    accordance with its investment objective.

The Fund may invest
in municipal lease
obligations         Each Portfolio may purchase municipal lease obligations,
                    which are securities issued by state and local governments
                    to acquire land, equipment and facilities. These obligations
                    typically are not backed by the issuing municipality's full
                    authority to assess taxes to meet its debt obligations. If
                    the issuing authority fails to make the appropriations
                    necessary to cover lease payments, then the lease may
                    terminate. In certain circumstances, the issuer could
                    default on the lease obligation and thereby cause a loss to
                    investors. Also, in certain circumstances, such as a default
                    or a termination of the lease, or all or a portion of the
                    payments attributable to the lease may be taxable as
                    ordinary income.

Derivative
Investing           Derivatives are instruments whose values are linked to or
                    derived from an underlying security or index. The most
                    common and conventional types of derivative securities are
                    futures and options.

The Insured
Long-Term Portfolio
may invest in
derivative 
securities          The Insured Long-Term Portfolio may invest in conventional
                    derivative securities, including futures contracts and
                    options, but only to a limited extent. The Portfolio may
                    enter into futures contracts provided that not more than 5%
                    of its assets are required as a futures contract deposit; in
                    addition, the Portfolio may enter into futures contracts and
                    options transactions only to the extent that obligations
                    under such contracts or transactions represent not more than
                    20% of the Portfolio's assets.
    
                    Futures contracts and options may be used for several common
                    fund management strategies: to maintain cash reserves while
                    simulating full investment, to facilitate trading, to reduce
                    transaction costs, or to seek higher investment returns when
                    a specific futures contract is priced more attractively than
                    other futures contracts or the underlying security or index.
                    The Fund may not use futures contracts or options
                    transactions to leverage its assets.

                    For example, in order to remain fully invested in bonds
                    while maintaining liquidity to meet potential shareholder
                    redemptions, the Pennsylvania Insured Long- Term Portfolio
                    may invest a portion of its assets in a bond futures
                    contract. Because futures contracts only require a small
                    initial margin deposit, the Portfolio would then be able to
                    maintain cash reserve to meet potential redemptions, while
                    at the same time remaining fully invested. Also, because the
                    transaction costs of futures and options may be lower than
                    the costs of investing in bonds directly, it is expected
                    that the use of futures contracts and options may reduce the
                    Portfolio's total transaction costs.

                    The Portfolio may use futures contracts for bona fide
                    "hedging" purposes. In executing a hedge, a manager sells,
                    for example, municipal bond futures contracts to protect
                    against a decline in the bond market. If the market drops,
                    the value of the futures position will rise, thereby
                    offsetting the decline in value of the portfolio's bond
                    holdings.

                    The Portfolio may invest in partnerships and grantor trust
                    derivative products. However, prior to the purchase of such
                    security, a determination must be made by the Portfolio that
                    the inherent risk of the partnership or grantor trust
                    derivative product is minimal.

Futures contracts
and options pose
risks               The primary risks associated with the use of futures
                    contracts and options are: (i) imperfect correlation between
                    the change in market value of the bonds held by a Portfolio
                    and the prices of futures contracts and options; and (ii)
                    possible lack of a liquid secondary market for a futures
                    contract and the resulting inability to close a futures
                    position prior to its maturity date. The risk of imperfect
                    correlation will be minimized by investing in those
                    contracts whose price fluctuations are expected to resemble
                    those of the Portfolio's underlying securities. The risk
                    that the Portfolio will be unable to close out a futures
                    position will be minimized by entering into such
                    transactions on a national exchange with an active and
                    liquid secondary market.

                    The risk of loss in trading futures contracts in some
                    strategies can be substantial, due both to the low margin
                    deposits required and the extremely high degree of

                                                                              15
<PAGE>

                    leverage involved in futures pricing. As a result, a
                    relatively small price movement in a futures contract may
                    result in immediate and substantial loss (or gain) to the
                    investor. When investing in futures contracts, the Portfolio
                    will segregate cash or cash equivalents in the amount of the
                    underlying obligation.
   
Partnerships and
grantor trusts pose
certain risks       The primary risks associated with partnerships and grantor
                    trust derivative products are (i) the possibility of a tax
                    ruling which affects the status of the state or federal
                    opinions which are necessary to support the issuance of the
                    derivative; (ii) the possibility that the tender option on a
                    security could be withdrawn upon the occurrence of certain
                    events; and (iii) the possible lack of a liquid secondary
                    market for the securities. The Portfolio will attempt to
                    minimize the risks of partnership and grantor trust
                    derivative products by carefully selecting which securities
                    to purchase and by constantly monitoring securities held by
                    the Portfolio.

                       securities, the interest on which is exempt from federal 
                       and Pennsylvania personal income taxes, except that it   
                       may make temporary investments as described in           
                       "Implementation of Policies."                            
                                                                             
                    c) At the close of each quarter of the taxable year, those  
                       issuers which represent more than 5% of a Portfolio's    
                       assets will be limited in aggregate to 50% of the assets 
                       of that Portfolio (except U.S. Government securities and 
                       cash items, as defined in the Code).                     
                                                                            
                    d) Each Portfolio will limit the aggregate value of holdings
                       of a single issuer (except U.S. Government and cash items
                       as defined in the Code) to a maximum of 25% of the       
                       Portfolio's total assets. For the purposes of this       
                       limitation, identification of the issuer will be based on
                       a determination of the source of assets and revenues     
                       committed to meeting interest and principal payments on  
                       each security.                                           
                                                                                
                    e) A Portfolio will not borrow money except for temporary or
                       emergency purposes, and then not in excess of 10% of the 
                       Portfolio's total assets. The Portfolio will repay all   
                       borrowings before making additional investments, and the 
                       interest paid on such borrowings will reduce income.     
                                                                                
                                                                             
                    f) A Portfolio will not pledge, mortgage, or hypothecate    
                       more than 10% of its total assets.

                       investment limitations described here and in the

MANAGEMENT
OF THE FUND         The Fund is a member of The Vanguard Group of Investment    
                    Companies, a family of more than 30 investment companies    
                    with more than 90 distinct investment portfolios and total  
Vanguard            assets in excess of $190 billion. Through their             
administers and     jointly-owned subsidiary, The Vanguard Group, Inc.          
distributes the     ("Vanguard"), the Fund and the other funds in the Group     
Fund                obtain at cost virtually all of their corporate management, 
                    administrative, shareholder accounting and distribution     
                    services. Vanguard also provides investment advisory        
                    services on an at-cost basis to certain Vanguard funds. As a
                    result of Vanguard's unique corporate structure, the        
                    Vanguard funds have costs substantially lower than those of 
                    most competing mutual funds. In 1995, the average expense   
                    ratio (annual costs including advisory fees divided by total
                    net assets) for the Vanguard funds amounted to approximately
                    .31% compared to an average of 1.11% for the mutual fund    
                    industry (data provided by Lipper Analytical Services).     
                                                                            
                    The Officers of the Fund manage its day-to-day operations   
                    and are responsible to the Fund's Trustees. The Trustees set
                    broad policies for the Fund and choose its Officers. A list 
                    of Trustees and Officers of the Fund and a statement of     
                    their present positions and principal occupations during the
                    past five years can be found in the Statement of Additional 
                    Information.                                                
                                                                                
                    Vanguard employs a supporting staff of management and       
                    administrative personnel needed to provide the requisite    
                    services to the funds and also furnishes the funds with     
                    necessary office space, furnishings and equipment. Each fund
                    pays its share of Vanguard's total expenses, which are      
                    allocated among the funds under methods approved by the     
                    Board of Trustees (Directors) of each fund. In addition,    
                    each fund bears its own direct expenses, such as legal,     
                    auditing and custodian fees.                                
                                                                                
                    Vanguard also provides distribution and marketing services  
                    to the Vanguard funds. The funds are available on a no-load 
                    basis (i.e., there are no sales commissions or 12b-1 fees). 
                    However, each fund bears its share of the Group's           
                    distribution costs.

INVESTMENT
ADVISER             The two Portfolios of the Fund receive all investment       
                    advisory services on an at-cost basis from Vanguard's Fixed 
                    Income Group. The Group provides investment advisory        
Vanguard manages    services to more than 40 Vanguard money market and bond     
the Fund's          portfolios, both taxable and tax-exempt. Total assets under 
investments         management by Vanguard's Fixed Income Group were            
                    approximately $66 billion as of December 31, 1995. The Fixed
                    Income Group is supervised by the Officers of the Fund. Ian 
                    A. MacKinnon, Senior Vice President of Vanguard, has been in
                    charge of the Group since its inception in 1981.            
                    

                                                                              17

                    o Reid Smith, a Principal of Vanguard, serves as portfolio
                      manager of the Pennsylvania Insured Long-Term Portfolio.
                      Mr. Smith has managed the Insured Long-Term Portfolio
                      since 1992. (Previously, the Insured Long-Term Portfolio
                      was managed by David Hamlin of the Fixed Income Group.)
                      For 3 years prior to joining Vanguard, Mr. Smith was
                      associated with another mutual fund advisory firm as a
                      fixed-income portfolio manager.


                    The Fixed Income Group manages the investment and
                    reinvestment of the assets of the Fund's Portfolios and
                    continuously reviews, supervises and administers each
                    Portfolio's investment program, subject to the maturity and
                    quality standards specified in this Prospectus, and
                    supplemental guidelines approved by the Fund's Board of
                    Trustees. The Fixed Income Group's selection of investments
                    for the Portfolios is based on: (a) continuing credit
                    analysis of those instruments held in the Portfolios and
                    those being considered for inclusion therein; (b) possible
                    disparities in yield relationships between different
                    fixed-income securities and money market instruments; and
                    (c) actual or anticipated movements in the general level of
                    interest rates.

                    Vanguard's Fixed Income Group places all orders for
                    purchases and sales of portfolio securities. Purchases of
                    portfolio securities are made either directly from the
                    issuer or from municipal securities dealers. The investment
                    management staff may sell portfolio securities prior to
                    their maturity if circumstances and considerations warrant
                    and if it believes such dispositions advisable. The Fund's
                    policy of investing in short-term instruments in the
                    Pennsylvania Money Market Portfolio will likely result in
                    significant portfolio turnover. The staff seeks to obtain
                    the best available net price and most favorable execution
                    for all portfolio transactions.

DIVIDENDS, CAPITAL
GAINS AND TAXES     Dividends consisting of virtually all of the ordinary income
                    of each Portfolio are declared daily and are payable to     
                    shareholders of record at the close of the previous business
The Fund pays       day. Such dividends are paid on the first business day of   
month-end           each month. Capital gains distributions, if any, will be    
dividends           made annually.                                              
                                                                            
                    Dividend and capital gains distributions may be             
                    automatically reinvested or received in cash. See "Choosing 
                    a Distribution Option" for a description of these           
                    distribution methods.                                       
                                                                                
                    In addition, in order to satisfy certain distribution       
                    requirements of the Tax Reform Act of 1986, each Portfolio  
                    may declare special year-end dividend and capital gains     
                    distributions during December. Such distributions, if       
                    received by shareholders by January 31, are deemed to have  
                    been paid by the Portfolio and received by shareholders by  
                    December 31 of the prior year.                              

Dividends will be
exempt from federal
and Pennsylvania
income taxes        Each Portfolio of the Fund intends to continue to qualify
                    for taxation as a "regulated investment company" under the
                    Internal Revenue Code so that each Portfolio will not be
                    subject to federal income tax to the extent its income is
                    distributed to shareholders. In addition, each Portfolio
                    intends to invest a sufficient portion of its assets in
                    municipal bonds and notes so that it will qualify to pay
                    "exempt- interest dividends" to shareholders. Such
                    exempt-interest dividends are excluded from a shareholder's

18
<PAGE>

                    gross income for federal tax purposes. The Revenue
                    Reconciliation Act enacted during 1993 provides that market
                    discount on tax-exempt bonds purchased after April 30, 1993
                    must be taxed as ordinary income. Accordingly, to the extent
                    that the Fund purchases such discounted securities, taxable
                    income may result. Furthermore, each Portfolio expects to
                    invest substantially all of its assets in Pennsylvania
                    municipal securities. As a result, each Portfolio will be
                    eligible to pay dividends to Pennsylvania residents that
                    will be exempt from Pennsylvania personal income taxes.


                    Net long-term capital gains realized by a Portfolio from the
                    sale of securities will be distributed as taxable capital
                    gains distributions for federal income tax purposes. Any
                    short-term capital gains or any taxable interest income will
                    be distributed as a taxable ordinary dividend distribution
                    for federal income tax purposes. In general, such taxable
                    income distributions from a Portfolio are expected to be
                    negligible in comparison with tax-exempt dividends. However,
                    under certain circumstances, a Portfolio may invest in
                    securities other than Pennsylvania municipal obligations. In
                    such cases, a portion of the Portfolio's income may be
                    subject to Pennsylvania income taxes, federal income taxes,
                    or both.

                    At present, neither Portfolio invests in AMT bonds. (See
                    "Investment Policies.") However, were a Portfolio to invest
                    in such bonds, all or a portion of the Portfolio's
                    dividends, while exempt from the regular federal income tax,
                    would be a tax preference item for purposes of the federal
                    alternative minimum tax.


A capital gain or loss
may be realized upon
exchange or
redemption          A sale of shares in the Insured Long-Term Portfolio is a    
                    taxable event and may result in a capital gain or loss. A   
                    capital gain or loss may be realized from an ordinary       
                    redemption of shares, a checkwriting redemption, or an      
                    exchange of shares between two mutual funds (or two         
                    portfolios of a mutual fund). In addition, if you held      
                    shares in the Insured Long-Term Portfolio for six months or 
                    less, any capital loss realized upon redemption is          
                    disallowed to the extent of the tax-exempt dividend income  
                    you received.                                               
                                                                             
                    Capital gains distributions from a Portfolio and any capital
                    gains or losses realized from the sale or exchange of shares
                    will generally be subject to state and local taxes.         
                                                                            
                    The Fund is required to withhold 31% of any taxable         
                    dividends, capital gains distributions, and redemptions paid
                    to shareholders who have not complied with IRS taxpayer     
                    identification regulations. You may avoid this withholding  
                    requirement by indicating your proper Social Security or    
                    Employer Identification number on your Account Registration 
                    Form and by certifying that you are not subject to backup   
                    withholding.                                                
                                                                                
                    Up to 85% of an individual's Social Security benefits may be
                    subject to federal income tax. Along with other factors,    
                    total tax-exempt income, including any tax-exempt dividend

                    Shares of the Portfolio are not subject to Pennsylvania
                    county personal property taxes. Further, distributions from
                    the Portfolios will be exempt from the Philadelphia School
                    District investment net income tax to the extent that such
                    distributions are derived from interest on Pennsylvania
                    obligations, or to the extent that such distributions are
                    designated as capital gain dividends for federal income tax
                    purposes.


                    The Fund is organized as a Pennsylvania business trust and,
                    in the opinion of counsel, is not liable for any income or
                    franchise tax in the Commonwealth of Pennsylvania. The Fund
                    will be subject to Pennsylvania county personal property tax
                    in the county which is the site of its principal office.

                    The tax discussion set forth above is included for general
                    information only. Prospective investors should consult their
                    own tax advisers concerning the tax consequences of an
                    investment in the Fund.

THE SHARE
PRICE OF EACH
PORTFOLIO           The share price or "net asset value" per share of each
                    Portfolio is determined daily by dividing the total value of
                    the investments and other assets of each Portfolio, less any
                    liabilities, by the total outstanding shares of such
                    Portfolio.

                    Pennsylvania Money Market Portfolio. For the purpose of
                    calculating the Pennsylvania Money Market Portfolio's net
                    asset value per share, securities are valued by the
                    "amortized cost" method of valuation, which does not take
                    into account unrealized gains or losses. This involves
                    valuing an instrument at its cost and thereafter assuming a
                    constant amortization to maturity of any discount or
                    premium, regardless of the impact of fluctuating interest
                    rates on the market value of the instrument. While this
                    method provides certainty in valuation, it may result in
                    periods during which value, as determined by amortized cost,
                    is higher or lower than the price the Portfolio would
                    receive if it sold the instrument.

                    The use of amortized cost and the maintenance of the
                    Pennsylvania Money Market Portfolio's per share net asset
                    value at $1.00 is based on its election to operate under the
                    provisions of Rule 2a-7 under the Investment Company Act of
                    1940. As a condition of operating under that rule, the
                    Pennsylvania Money Market Portfolio must maintain a
                    dollar-weighted average portfolio maturity of 90 days or
                    less, purchase only instruments having remaining maturities
                    of 13 months or less, and invest only in securities that are
                    determined by the Trustees to present minimal credit risks
                    and that are of high quality as determined by any major
                    rating service, or in the case of any instrument not so
                    rated, considered by the Trustees to be of comparable
                    quality.

                    The Trustees have established procedures designed to
                    stabilize the net asset value per share, as computed for the
                    purposes of sales and redemptions, at $1.00. These
                    procedures include periodic review, as the Trustees deem
                    appropriate and at such intervals as are reasonable in light
                    of current market conditions, of the relationship between
                    the amortized cost value per share and a net asset value per
                    share based upon available indications of market value. In
                    such a review, investments for which market quotations are
                    readily available are valued at the most recent bid

                    price or quoted yield equivalent for such securities or for
                    securities of comparable maturity, quality and type as
                    obtained from one or more of the major market makers for the
                    securities to be valued. Other investments and assets are
                    valued at fair value, as determined in good faith by the
                    Trustees.

                    In the event of a deviation of over 1/2 of 1% between a
                    Portfolio's net asset value based upon available market
                    quotations or market equivalents and $1.00 per share based
                    on amortized cost, the Trustees will promptly consider what
                    action, if any, should be taken. The Trustees will also take
                    such action as they deem appropriate to eliminate or to
                    reduce, to the extent reasonably practicable, any material
                    dilution or other unfair results to investors or existing
                    shareholders which might arise from differences between the
                    two. Such action may include redeeming shares in kind,
                    selling instruments prior to maturity to realize capital
                    gains or losses or to shorten average maturity, withholding
                    dividends, paying distributions from capital or capital
                    gains, or utilizing a new asset value per share based upon
                    available market quotations.


                    Pennsylvania Insured Long-Term Portfolio. The net asset
                    value per share of the Pennsylvania Insured Long-Term
                    Portfolio is determined as of the close of regular trading
                    on the New York Stock Exchange (generally 4:00 p.m. Eastern
                    time) on each day the Exchange is open for business. When
                    approved by the Board of Trustees, bonds and other
                    fixed-income securities of the Portfolio may be valued on
                    the basis of the prices provided by a pricing service when
                    such prices are believed to reflect the fair market value of
                    such securities. (The prices provided by pricing services
                    are generally determined without regard to bid or last sale
                    prices. Because of the large number of outstanding municipal
                    bonds, the majority of issues do not trade each day;
                    therefore, last sale prices are not normally available. In
                    valuing such securities, the pricing services generally take
                    into account institutional size trading in similar groups of
                    securities and any developments related to specific
                    securities.) The methods used by the pricing service and the
                    valuations so established are reviewed by the Officers of
                    the Fund under the general supervision of Trustees. There
                    are a number of pricing services available and the Trustees,
                    on the basis of on-going evaluation of these services, may
                    use other pricing services or discontinue the use of any
                    pricing service.

                    Securities not priced in this manner are priced at the most
                    recent quoted bid price provided by investment dealers.
                    Short-term instruments maturing within 60 days of the
                    valuation date may be valued at cost, plus or minus any
                    amortized discount or premium. Other assets and securities
                    for which no quotations are readily available will be valued
                    in good faith at their fair value using methods determined
                    by the Trustees.

                    The price per share of the Insured Long-Term Portfolio can
                    be found daily in the mutual fund section of most major
                    newspapers under the heading of Vanguard.

GENERAL
INFORMATION         Vanguard Pennsylvania Tax-Free Fund is a Pennsylvania
                    business trust. The Declaration of Trust permits the
                    Trustees to issue an unlimited number of shares of
                    beneficial interest, without par value, from an unlimited
                    number of classes of shares. Currently the Fund is offering
                    two classes of shares (known as "Portfolios").

                    Shares of each Portfolio, when issued, are fully paid and

                    distributions and net assets; are entitled to one vote per
                    share; have pro rata liquidation rights; and do not have
                    pre-emptive rights. Also, shares of the Fund have
                    non-cumulative voting rights, meaning that the holders of

                    required by the Investment Company Act of 1940 and other
                    applicable law. An annual meeting will be held to vote on
                    the removal of a Trustee or Trustees of the Fund if
                    requested in writing by the holders of not less than 10% of
                    the outstanding shares of the Fund.

                    All securities and cash are held by CoreStates Bank, N.A.,

ACCOUNT AND
PURCHASING

                    complete and return an Account Registration Form and any
                    required legal documentation. Please indicate the Portfolio
                    you have chosen and the amount you wish to invest. Your
                    purchase must be equal to or greater than the $3,000 minimum
                    initial investment requirement ($1,000 for Uniform
                    Gift/Transfer to Minors Act Accounts). In addition, you must
                    be a Pennsylvania resident to invest in the Fund. If you
                    need assistance with the Account Registration Form or have
                    any questions, please call our Investor Information
                    Department at 1-800-662-7447. Note: For other types of
                    account registrations (e.g., corporations, associations,
                    other organizations, trusts or powers of attorney), please
                    call us to determine which additional forms you may need.

                    Each Portfolio's shares generally are purchased at the
                    next-determined net asset value after your investment has
                    been received in the form of Federal Funds. See "When Your
                    Account Will Be Credited". The Fund is offered on a no-load
                    basis (i.e., there are no sales commissions or 12b-1 fees).

Purchase
Restrictions        1) Because of the risks associated with bond investments,
                    the Fund is intended to be a long-term investment vehicle
                    and is not designed to provide investors with a means of
                    speculating on short-term market movements. Consequently,
                    the Fund reserves the right to reject any specific purchase
                    (and exchange purchase) request. The Fund also reserves the
                    right to suspend the offering of shares for a period of
                    time.

                    2) Vanguard will not accept third-party checks to purchase
                    shares of the Fund. Please be sure your purchase check is
                    made payable to the Vanguard Group.

                    In addition, an option to invest your cash dividends and/or
                    capital gains distributions in another Vanguard Fund account
                    is available. Please call our Client Services Department
                    (1-800-662-2739) for information. You may also elect
                    Vanguard Dividend Express which allows you to transfer your
                    cash dividends and/or capital gains distributions
                    automatically to your bank account. Please see "Other
                    Vanguard Services" for more information.

TAX CAUTION         Under Federal tax laws, the Fund is required to distribute  
                    net capital gains and investment income to Fund             
                    shareholders. These distributions are made to all           
Investors should    shareholders who own Fund shares as of the distribution's   
ask about the       record date, regardless of how long the shares have been    
timing of capital   owned. Purchasing shares just prior to the record date could
gains and dividend  have a significant impact on your tax liability for the     
distributions       year. For example, if you purchase shares immediately prior 
before investing    to the record date of a sizable capital gain, you will be   
                    assessed taxes on the amount of the capital gain            
                    distribution later paid even though you owned the Fund      
                    shares for just a short period of time. (Taxes are due on   
                    the distributions even if the capital gain is reinvested in 
                    additional Fund shares.) While the total value of your      
                    investment will be the same after the capital gain          
                    distribution--the amount of the capital gain distribution   
                    will offset the drop in the net asset value of the          
                    shares--you should be aware of the tax implications the     
                    timing of your purchase may have.                           
                                                                            
                    Prospective investors should, therefore, inquire about      
                    potential distributions before investing. The Fund's annual 
                    capital gains distribution normally occurs in December,     
                    while income dividends are generally paid on the first      
                    business day of each month. For additional information on   
                    distributions and taxes, see the section titled "Dividends, 
                    Capital Gains, and Taxes."

WHEN YOUR
ACCOUNT WILL
BE CREDITED         The trade date is the date on which your account is
                    credited. It is generally the day on which the Fund receives
                    your investment in the form of Federal Funds (monies
                    credited to the Fund's Custodian Bank by a Federal Reserve
                    Bank). Your trade date varies according to your method of
                    payment for your shares.

                    Purchases of Fund shares by check (except the Money Market
                    Portfolio) will receive a trade date the day the funds are
                    received in good order by Vanguard. Thus, if your purchase
                    by check is received by the close of regular trading on the
                    New York Stock Exchange (generally 4:00 p.m. Eastern time),
                    your trade date is the business day your check is received
                    in good order. If your purchase is received after the close
                    of the Exchange your trade date is the business day
                    following receipt of your check.

                    For purchases by check for the Money Market Portfolio, the
                    Fund is ordinarily credited with Federal Funds within one
                    business day. Thus, if your purchase by check is received by
                    the close of regular trading on the New York Stock Exchange
                    (generally 4:00 p.m. Eastern time), your trade date is the
                    business day following receipt of your check. If your
                    purchase is received after the close of the Exchange, your
                    trade date is the second business day following receipt of
                    your check.

                    For purchases by Federal Funds wire or exchange, the Fund is
                    credited immediately with Federal Funds. Thus, if your
                    purchase by Federal Funds wire or exchange is received by
                    the close of the Exchange, your trade date is the day of
                    receipt. If your purchase is received after the close of the
                    Exchange, your trade date is the business day following
                    receipt of your wire or exchange.

                    Your shares are purchased at the net asset value determined
                    on your trade date. You will begin to earn dividends on the
                    calendar day following the trade date. (For a Friday trade
                    date, you will begin earning dividends on Saturday.) For a
                    purchase of the Money Market Portfolio by Federal Funds
                    wire, you may qualify for a dividend on the date of purchase
                    if you have notified the Fund of your intention to make the
                    purchase by 10:45 a.m. (Eastern time) on the business day of
                    the wire.

                    In order to prevent lengthy processing delays caused by the
                    clearing of foreign checks, Vanguard will only accept a
                    foreign check which has been drawn in U.S. dollars and has
                    been issued by a foreign bank with a U.S. correspondent
                    bank.

                    The name of the U.S. correspondent bank must be printed on
                    the face of the foreign check.

                    request by writing or by telephoning. Your redemption
                    proceeds are normally mailed, credited or wired--depending
                    upon the method of withdrawal you have previously

                    presented for payment to the Fund's agent, CoreStates Bank,
                    the Fund will redeem sufficient shares in your account at
                    the next determined net asset value to cover the amount of
                    the check.

                    In order to establish the checkwriting option on your
                    account, all registered shareholders must sign a signature
                    card. After your completed signature card is received by the
                    Fund, an initial supply of checks will be mailed within 10

                    before submitting signature cards, as additional documents
                    may be required to establish the checkwriting service.

                    Before establishing the checkwriting option, you should be

Selling By
Telephone           To sell shares by telephone, you or your pre-authorized
                    representative may call our Client Services Department at
                    1-800-662-2739. For telephone redemptions, you may have the
                    proceeds sent to you by mail or by wire. In addition to the
                    details, please see "Important Information About Telephone
                    Transactions."

                    By Mail: Telephone mail redemption is automatically
                    established on your account unless you indicate otherwise on
                    your Account Registration Form. You may redeem any amount by
                    calling Vanguard. The proceeds will be paid to the
                    registered shareholders and mailed to the address of record.
                    Please Note: As a protection against fraud, your telephone
                    mail redemption privilege will be suspended for 10 calendar
                    days following any expedited address change to your account.
                    An expedited address change is one that is made by
                    telephone, by Vanguard Online or, in writing, without the
                    signatures of all account owners.

                    By Wire: Telephone wire redemption must be specifically
                    elected for your account. The best time to elect telephone
                    wire redemption is at the time you complete your Account
                    Registration Form. If you do not presently have telephone
                    wire redemption and wish to establish it, please contact our
                    Client Services Department.

                    With the wire redemption option, you may withdraw a minimum
                    of $1,000 and have the amount wired directly to your bank
                    account. Wire redemptions less than $5,000 are subject to a
                    $5 charge deducted by Vanguard. There is no Vanguard charge
                    for wire redemptions of $5,000 or more. However, your bank
                    may assess a separate fee to accept incoming wires.

                    A request to change the bank associated with your wire
                    redemption option must be received in writing, signed by
                    each registered shareholder, and accompanied by a voided
                    check or preprinted deposit slip. A signature guarantee is
                    required if your bank registration is not identical to your
                    Vanguard Fund account registration. 

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

Selling By Fund 
Express             If you select the Fund Express Automatic Withdrawal option,

Withdrawal &        have selected. The Special Redemption option lets you move

Important
Redemption
Information         Shares purchased by check or Fund Express may be redeemed at
                    any time. However, your redemption proceeds will not be paid
                    until payment for the purchase is collected, which may take
                    up to ten calendar days.

Delivery of
Redemption
Proceeds            Redemption requests received by telephone prior to the close
                    of regular trading on the New York Stock Exchange (generally
                    4:00 p.m. Eastern time) are processed on the day of receipt
                    and the redemption proceeds are normally sent on the
                    following business day.

                    Redemption requests received by telephone after the close of
                    the Exchange are processed on the business day following
                    receipt and the proceeds are normally sent on the second
                    business day following receipt.
                                 
                    Redemption proceeds must be sent to you within seven days of
                    receipt of your request in Good Order, except as described
                    in "Important Redemption Information".
                                 
                    If you experience difficulty in making a telephone
                    redemption during periods of drastic economic or market
                    changes, your redemption request may be made by regular or
                    express mail. It will be implemented at the net asset value
                    next determined after your request has been received by
                    Vanguard in Good Order. The Fund reserves the right to
                    revise or terminate the telephone redemption privilege at
                    any time.
                                 
                    The Fund may suspend the redemption right or postpone
                    payment at times when the New York Stock Exchange is closed
                    or under any emergency circumstances as determined by the
                    United States Securities and Exchange Commission.

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

Vanguard's Average
Cost Statement      If you make a redemption from a qualifying account, Vanguard
                    will send you an Average Cost Statement which provides you
                    with the tax basis of the shares you redeemed. Please see
                    "Statements and Reports" for additional information.
                                 
                    -----------------------------------------------------------

Low Balance Fee and
Minimum Account
Balance
Requirement         Due to the relatively high cost of maintaining smaller
                    accounts, the Fund will automatically deduct a $10 annual
                    fee from accounts with balances falling below $2,500 ($1,000
                    for Uniform Gifts/Transfers to Minors Act accounts). This
                    fee deduction will occur mid-year, beginning in 1996. The
                    fee generally will be waived for investors whose aggregate
                    Vanguard assets exceed $50,000.
                                 
                    In addition, the Fund reserves the right to liquidate any
                    non-retirement account that is below the minimum initial
                    investment amount of $3,000. If at any time your total
                    investment does not have a value of at least $3,000, you may
                    be notified that your account is below the Fund's minimum
                    account balance requirements. You would then be allowed 60
                    days to make an additional investment before the account is
                    liquidated. Proceeds would be promptly paid to the
                    registered shareholder.
                                
                    Vanguard will not liquidate your account if it has fallen
                    below $3,000 solely as a result of declining markets (i.e.,
                    a decline in a Portfolio's asset value).

Important Exchange
Information         Before you make an exchange, you should consider the
                    following:
                                
                    o Please read the fund's prospectus before making an
                      exchange. For a copy and for answers to any questions you
                      may have, call our Investor Information Department
                      (1-800-662-7447).
                                
                    o An exchange is treated as a redemption and a purchase.
                      Therefore, you could realize a taxable gain or loss on the
                      transaction.

                    o Exchanges are accepted only if the registrations and
                      Taxpayer Identification numbers of the two accounts are
                      identical.

                    o The shares to be exchanged must be on deposit and not held
                      in certificate form.

                    o New accounts are not currently accepted in
                      Vanguard/Windsor Fund or Vanguard/PRIMECAP Fund.

                    o The redemption price of shares redeemed by exchange is the
                      net asset value next determined after Vanguard has
                      received the required documentation in Good Order.
                                 
                    o When opening a new account by exchange, you must meet the
                      minimum investment requirement of the new fund.

                    Every effort will be made to maintain the exchange
                    privilege. However, the Fund reserves the right to revise or
                    terminate its provisions, limit the amount of or reject any
                    exchange, as deemed necessary, at any time.
                               
                    The Fund's exchange privilege is only available in
                    Pennsylvania, the only state in which the Fund's shares are
                    registered for sale.

EXCHANGE
PRIVILEGE
LIMITATIONS         The Fund's exchange privilege is not intended to afford     
                    shareholders a way to speculate on short-term movements in
                    the market. Accordingly, in order to prevent excessive use
                    of the exchange privilege that may potentially disrupt the
                    management of the Fund and increase transaction costs, the
                    Fund has established a policy of limiting excessive exchange
                    activity.

                    Exchange activity generally will not be deemed excessive if
                    limited to two substantive exchange redemptions (at least 30
                    days apart) from a Portfolio during any twelve-month period.
                    These limitations do not apply to exchanges from Vanguard's
                    money market portfolios. Notwithstanding these limitations,
                    the Fund reserves the right to reject any purchase request
                    (including exchange purchases from other Vanguard
                    portfolios) that is reasonably deemed to be disruptive to
                    efficient portfolio management.

IMPORTANT
INFORMATION
ABOUT TELEPHONE
TRANSACTIONS        The ability to initiate redemptions (except wire
                    redemptions) and exchanges by telephone is automatically
                    established on your account unless you request in writing
                    that telephone transactions on your account not be
                    permitted. The ability to initiate wire redemptions by
                    telephone will be established on your account only if you
                    specifically elect this option in writing.

                    To protect your account from losses resulting from
                    unauthorized or fraudulent telephone instructions, Vanguard
                    adheres to the following security procedures:

                    1. Security Check. To request a transaction by telephone,
                    the caller must know (i) the name of the Portfolio; (ii) the
                    10-digit account number; (iii) the exact name and address
                    used in the registration; and (iv) the Social Security or
                    Employer Identification number listed on the account.

                    2. Payment Policy. The proceeds of any telephone redemption
                    by mail will be made payable to the registered shareowner
                    and mailed to the address of record, only. In the case of a
                    telephone redemption by wire, the wire transfer will be made
                    only in accordance with the shareowner's prior written
                    instructions.

                    Neither the Fund nor Vanguard will be responsible for the
                    authenticity of transaction instructions received by
                    telephone, provided that reasonable security procedures have
                    been followed. Vanguard believes that the security
                    procedures described above are reasonable, and that if such
                    procedures are followed, you will bear the risk of any
                    losses resulting from unauthorized or fraudulent telephone
                    transactions on your account. If Vanguard fails to follow
                    reasonable security procedures, it may be liable for any
                    losses resulting from unauthorized or fraudulent telephone
                    transactions on your account.

STATEMENTS AND 
REPORTS             Vanguard will send you a confirmation statement each time
                    you initiate a transaction in your account except for
                    checkwriting redemptions from Vanguard money market
                    accounts. You will also receive a comprehensive account
                    statement at the end of each calendar quarter. The
                    fourth-quarter statement will be a year-end statement,
                    listing all transaction activity for the entire calendar
                    year.

                    Vanguard's Average Cost Statement provides you with the
                    average cost of shares redeemed from your account, using the
                    average cost single category method. This service is

                            INVESTMENT LIMITATIONS 

   The following limitations cannot be changed without the consent of the 
holders of a majority of the Fund's outstanding shares (as defined in the 
Investment Company Act of 1940 (the "1940 Act"), including a majority of the 
shares of each Portfolio. 


   1. Each Portfolio will limit the aggregate value of all issuers (except 
U.S. Government and cash items, as defined under Subchapter M of the Internal 
Revenue Code (the "Code"), each of which exceeds 5% of the Portfolio's total 
assets, to an aggregate amount of 50% of such assets; 


   2. Each Portfolio will limit the aggregate value of holdings of a single 
issuer (except U.S. government and cash items, as defined in the Code) to a 
maximum of 25% of the Portfolio's total assets. For the purposes of this 
limitation, identification of the issuer will be based on a determination of 
the source of assets and revenues committed to meeting interest and principal 
payments of each security; 

   3. Each Portfolio will not borrow money except for temporary or emergency 
purposes, and then only in an amount not exceeding 10% of the value of the 
total assets of that Portfolio. The Portfolio will repay all borrowings 
before making additional investments. Interest paid on such borrowings will 
reduce income; 

   4. Each Portfolio will not pledge, mortgage or hypothecate its assets to 
any extent greater than 10% of the value of the total assets of the 
Portfolio; 

   5. Each Portfolio will not issue senior securities as defined in the 1940 
Act; 

   6. Each Portfolio will not engage in the business of underwriting 
securities issued by other persons, except to the extent that the Portfolio 
may technically be deemed an underwriter under the Securities Act of 1933, as 
amended, in disposing of portfolio securities; 

                                                                             B-1
<PAGE>



   7. Each Portfolio will not purchase or otherwise acquire any security, if 
as a result, more than 15% (10% with respect to the Money Market Portfolio) 
of its net assets would be invested in securities that are illiquid (included 
in this limitation is the Fund's investment in The Vanguard Group, Inc.); 


   8. Each Portfolio will not purchase or sell real estate, but this shall 
not prevent investments in municipal bonds secured by real estate or 
interests therein; 

   9. Each Portfolio will not make loans to other persons, except by the 
purchase of bonds, debentures or similar obligations which are publicly 
distributed and as provided under "Lending of Securities"; 

   10. Each Portfolio will not purchase on margin or sell short, except as 
specified below in Investment Limitation No. 12; 

   11. Each Portfolio will not purchase or retain securities of an issuer if 
those Trustees of the Fund, each of whom owns more than 1/2 of 1% of such 
securities, together own more than 5% of the securities of such issuer: 

   12. Each Portfolio will not purchase or sell commodities or commodities 
contracts, except that the Pennsylvania Insured Long-Term Portfolio may 
invest in bond futures contracts, bond options and options on bond futures 
contracts to the extent that not more than 5% of the Portfolio's assets are 
required as deposit on futures contracts and not more than 20% of the 
Portfolio's assets are invested in futures contracts and/or options 
transactions at any time; 

   13. Each Portfolio will not invest its assets in securities of other 
investment companies except as they may be part of a merger, consolidation, 
reorganization or acquisition of assets or otherwise to the extent permitted 
by Section 12 of the 1940 Act; 

   14. Each Portfolio will not invest in securities other than municipal 
bonds, except that each Portfolio may make temporary investments in (a) notes 
issued by or on behalf of municipal or corporate issuers, obligations of the 
U.S. Government and its agencies, commercial paper and bank certificates of 
deposit; (b) investment companies investing in such securities which have 
investment objectives consistent with those of the Portfolio to the extent 
permitted by the 1940 Act; and (c) any such securities or municipal bonds 
subject to repurchase agreements; 

   15. Each Portfolio will not invest in put, call, straddle or spread 
options (except as described above in investment limitation No. 12) or 
interests in oil, gas or other mineral exploration or development programs; 

   16. Each Portfolio will not purchase an industrial revenue bond if as a 
result of such purchase (i) more than 5% of the Portfolio's total assets, 
determined at market value at the time of the proposed investment, would be 
invested in industrial revenue bonds where the payment of principal and 
interest is the responsibility of a company with less than three (3) years' 
operating history; or (ii) more than 20% of the Portfolio's total assets, 
determined at market value at the time of the proposed investment, would be 
invested in industrial development bonds. These restrictions do not apply to 
municipal obligations where the payment of principal and interest is the 
responsibility of a government or the political subdivision of a government. 
   
   The above-mentioned investment limitations are considered at the time
investment securities are purchased. Notwithstanding these limitations, each
Portfolio may own all or any portion of the securities of, or make loans to, or
contribute to the costs or other financial requirements of, any company which
will be (1) wholly-owned by the Fund and one or more other investment companies
and (2) primarily engaged in the business of providing, at cost, management,
administrative, distribution and/or related services to the Fund and such other
investment companies. Additionally, the Fund may invest in when-issued
securities without limitation. Please see the prospectus for a description of
such securities.

                             INVESTMENT POLICIES 

   
   Lending of Securities. Each Portfolio may lend its investment securities to 
qualified institutions who need to borrow securities in order to complete 
certain transactions, such as covering short sales, avoiding failures to 
deliver securities or completing arbitrage operations. By lending its 
investment securities, the Portfolio attempts to increase its income through 
the receipt of interest on the loan. Anygain or loss in the market price of
the securities loaned that might occur during the term of the loan would be for
the account of the Portfolio. The Portfolio may lend its investment securities
to qualified brokers, dealers, banks or other financial institutions, so long as
the terms and the structure of such loans are not inconsistent with the 1940
Act, or the Rules and Regulations or interpretations of the Securities and
Exchange Commission (the "Commission") thereunder, which currently require that
(a) the borrower pledge and maintain with the Portfolio collateral having a
value at all times not less than 100% of the value of the securities loaned, (b)
the borrower add to such collateral whenever the price of the securities loaned
rises (i.e., the borrower "marks to the market" on a daily basis), (c) the loan
be made subject to termination by the Portfolio at any time and (d) the
Portfolio receive reasonable interest on the loan (which may include the
Portfolio investing any cash collateral in interest bearing short- term
investments), any distribution on the loaned securities and any increase in
their market value. A Portfolio will not lend its investment securities, if as a
result, the aggregate of such loans exceeds 10% of the value of its total
assets. Loan arrangements made by the Portfolio will comply with all other
applicable regulatory requirements, including the rules of the New York Stock
Exchange, which rules presently require the borrower, after notice, to redeliver
the securities within the normal settlement time of three business days. All
relevant facts and circumstances, including the creditworthiness of the broker,
dealer or institution, will be considered in making decisions with respect to
the lending of securities, subject to review by the Fund's Board of Trustees.
Income derived from lending of securities is not tax- exempt, and, thus, a
portfolio will limit such activity in accordance with its investment objective.

   Futures Contracts and Options. The Insured Long-Term Portfolio may enter 
into futures contracts, options, and options on futures contracts for the 
purpose of simulating full investment and reducing transactions costs. 
Futures contracts provide for the future sale by one party and purchase by 
another party of a specified amount of a specific security at a specified 
future time and at a specified price. Futures contracts which are 
standardized as to maturity date and underlying financial instrument are 
traded on national futures exchanges. Futures exchanges and trading are 
regulated under the Commodity Exchange Act by the Commodity Futures Trading 
Commission ("CFTC"), a U.S. Government Agency. 
    
   Although futures contracts by their terms call for actual delivery or 
acceptance of the underlying securities, in most cases the contracts are 
closed out before the settlement date without the making or taking of 
delivery. Closing out an open futures position is done by taking an opposite 
position ("buying" a contract which has previously been "sold," or "selling" 
a contract previously purchased) in an identical contract to terminate the 
position. Brokerage commissions are incurred when a futures contract is 
bought or sold. 

   Futures traders are required to make a good faith margin deposit in cash 
or government securities with a broker or custodian to initiate and maintain 
open positions in futures contracts. A margin deposit is intended to assure 
completion of the contract (delivery or acceptance of the underlying 
security) if it is not terminated prior to the specified delivery date. 
Minimal initial margin requirements are established by the futures exchange 
and may be changed. Brokers may establish deposit requirements which are 
higher than the exchange minimums. Futures contracts are customarily 
purchased and sold at prices which may range upward from less than 5% of the 
value of the contract being traded. 

   After a futures contract position is opened, the value of the contract is 
marked to market daily. If the futures contract price changes, to the extent 
that the margin on deposit does not satisfy margin requirements, payment of 
additional "variation" margin will be required. Conversely, changes in the 
contract value may reduce the required margin, resulting in a repayment of 
excess margin to the contract holder. Variation margin payments are made to 
and from the futures broker for as long as the contract remains open. The 
Fund expects to earn interest income on its margin deposits. 

   Traders in futures contracts may be broadly classified as either "hedgers" 
or "speculators." Hedgers use the futures markets primarily to offset 
unfavorable changes in the value of securities otherwise held for investment 
purposes or expected to be acquired by them. Speculators are less inclined to 
own the securities underlying the futures contracts which they trade, and use 
futures contracts with the expectation of realizing profits from fluctuations 
in the interest rate of underlying securities. The Fund intends to use 
futures contracts only for bona fide hedging purposes. 

                                                                          B-3
<PAGE>

   Regulations of the CFTC applicable to the Fund require that all of its 
futures transactions constitute bona fide hedging transactions. The Insured 
Long-Term Portfolio will only sell futures contracts to protect securities it 
owns against price declines or purchase contracts to protect against an 
increase in the price of securities it intends to purchase. As evidence of 
this hedging interest, the Portfolio expects that approximately 75% of its 
futures contract purchases will be "completed," that is, equivalent amounts 
of related securities will have been purchased or are being purchased by the 
Portfolio upon sale of open futures contracts. 

   Although techniques other than the sale and purchase of futures contracts 
could be used to control the Portfolio's exposure to market fluctuations, the 
use of futures contracts may be a more effective means of hedging this 
exposure. While the Portfolio will incur commission expenses in both opening 
and closing out futures positions, these costs are lower than transaction 
costs incurred in the purchase and sale of the underlying securities. 
   
   Restrictions on the Use of Futures Contracts. The Insured Long-Term 
Portfolio will not enter into futures contract transactions to the extent 
that, immediately thereafter, the sum of its initial margin deposits on open 
contracts exceeds 5% of the market value of the Fund's total assets. In 
addition, the Portfolio will not enter into futures contracts to the extent 
that its outstanding obligations to purchase securities under these contracts 
would exceed 20% of the Portfolio's total assets. Assets committed to futures 
contracts or options will be held in a segregated account at the Fund's 
custodian bank. 

   Risk Factors in Futures Transactions. Positions in futures contracts may be 
closed out only on an Exchange which provides a secondary market for such 
futures. However, there can be no assurance that a liquid secondary market 
will exist for any particular futures contract at any specific time. Thus, it 
may not be possible to close a futures position. In the event of adverse 
price movements, the Insured Long-Term Portfolio would continue to be 
required to make daily cash payments to maintain its required margin. In such 
situations, if the Portfolio has insufficient cash, it may have to sell 
portfolio securities to meet daily margin requirements at a time when it may 
be disadvantageous to do so. In addition, the Portfolio may be required to 
make delivery of the instruments underlying futures contracts it holds. The 
inability to close options and futures positions also could have an adverse 
impact on the ability to effectively hedge the Portfolio. 
    
   The Insured Long-Term Portfolio will minimize the risk that it will be 
unable to close out a futures contract by only entering into futures which 
are traded on national futures exchanges and for which there appears to be a 
liquid secondary market. 

   The risk of loss in trading futures contracts in some strategies can be 
substantial, due both to the low margin deposits required, and the extremely 
high degree of leverage involved in futures pricing. As a result, a 
relatively small price movement in a futures contract may result in immediate 
and substantial loss (as well as gain) to the investor. For example, if at 
the time of purchase, 10% of the value of the futures contract is deposited 
as margin, a subsequent 10% decrease in the value of the futures contract 
would result in a total loss of the margin deposit, before any deduction for 
the transaction costs, if the account were then closed out. A 15% decrease 
would result in a loss equal to 150% of the original margin deposit if the 
contract were closed out. Thus, a purchase or sale of a futures contract may 
result in losses in excess of the amount invested in the contract. However, 
because the futures strategies of the Portfolio are engaged in only for 
hedging purposes, the Adviser does not believe that the Portfolio is subject 
to the risks of loss frequently associated with futures transactions. The 
Portfolio would presumably have sustained comparable losses if, instead of 
the futures contract, it had invested in the underlying financial instrument 
and sold it after the decline. 

   Utilization of futures transactions by the Portfolio does not involve the 
risk of imperfect or no correlation where the securities underlying futures 
contracts have different maturities in other characteristics than the 
portfolio securities being hedged. It is also possible that the Portfolio 
could both lose money on futures contracts and also experience a decline in 
value of its portfolio securities. There is also the risk of loss by the 
Portfolio of margin deposits in the event of bankruptcy of a broker with whom 
the Portfolio has an open position in a futures contract or related option. 

B-4
<PAGE>
   Most futures exchanges limit the amount of fluctuation permitted in 
futures contract prices during a single trading day. The daily limit 
establishes the maximum amount that the price of a futures contract may vary 
either up or down from the previous day's settlement price at the end of a 
trading session. Once the daily limit has been reached in a particular type 
of contract, no trades may be made on that day at a price beyond that limit. 
The daily limit governs only price movement during a particular trading day 
and therefore does not limit potential losses, because the limit may prevent 
the liquidation of unfavorable positions. Futures contract prices have 
occasionally moved to the daily limit for several consecutive trading days 
with little or no trading, thereby preventing prompt liquidation of future 
positions and subjecting some futures traders to substantial losses. 
   
   Federal Tax Treatment of Futures Contracts. The Insured Long-Term Portfolio 
is required for federal income tax purposes to recognize as income for each 
taxable year their net unrealized gains and losses on certain futures 
contracts held as of the end of the year as well as those actually realized 
during the year. In most cases, any gain or loss recognized with respect to a 
futures contract is considered to be 60% long-term capital gain or loss and 
40% short-term capital gain or loss, without regard to the holding period of 
the contract. Furthermore, sales of futures contracts which are intended to 
hedge against a change in the value of securities held by the Portfolio may 
affect the holding period of such securities and, consequently, the nature of 
the gain or loss on such securities upon disposition. The Portfolio may be 
required to defer the recognition of losses on futures contracts to the 
extent of any unrecognized gains on related positions held by the Portfolio. 
    
   In order for a Portfolio to continue to qualify for federal income tax 
treatment as a regulated investment company, at least 90% of its gross income 
for a taxable year must be derived from qualifying income; i.e., dividends, 
interest, income derived from loans of securities, gains from the sale of 
securities or of foreign currencies or other income derived with respect to 
the Portfolio's business of investing in securities. In addition, gains 
realized on the sale or other disposition of securities held for less than 
three months must be limited to less than 30% of the Portfolio's annual gross 
income. It is anticipated that any net gain realized from the closing out of 
futures contracts will be considered gain from the sale of securities and 
therefore be qualifying income for purposes of the 90% requirement. In order 
to avoid realizing excessive gains on securities held less than three months, 
the Insured Long-Term Portfolio may be required to defer the closing out of 
futures contracts beyond the time when it would otherwise be advantageous to 
do so. It is anticipated that unrealized gains on futures contracts, which 
have been open for less than three months as of the end of the Portfolio's 
fiscal year and which are recognized for tax purposes, will not be considered 
gains on sales of securities held less than three months for the purpose of 
the 30% test. 

   Each Portfolio will distribute to shareholders annually any net capital 
gains which have been recognized for federal income tax purposes (including 
unrealized gains at the end of the Portfolio's fiscal year) on futures 
transactions. Such distributions will be combined with distributions of 
capital gains realized on the Portfolio's other investments and shareholders 
will be advised on the nature of the transactions. 


                                 RISK FACTORS 
                     VANGUARD PENNSYLVANIA TAX-FREE FUND 

   Vanguard Pennsylvania Tax-Free Fund invests primarily in the obligations 
of Pennsylvania state government, state agencies and various local 
governments, including counties, cities, townships, special districts, and 
authorities. In general, the credit quality and credit risk of any issuer's 
debt depend on the state and local economy, the health of the issuer's 
finances, the amount of the issuer's debt, the quality of management, and the 
strength of legal provisions in debt documents that protect debt holders. 
Credit risk is usually lower wherever the economy is strong, growing and 
diversified; financial operations are sound; and the debt burden is 
reasonable. 

   The average rating among American states for full faith and credit state 
debt is "Aa" and "AA" by Moody's Investors Service and Standard & Poor's 
Corporation, respectively. Against this measure and the criteria listed 
above, the credit risk associated with direct obligations of Pennsylvania and 

                                                                             B-5

State agencies, including general obligation and revenue bonds, lease debt, and
notes, compares somewhat unfavorably. During most of the last two decades,
Pennsylvania's general obligation bonds have been rated just below this average
by both rating agencies. Nonetheless, during this period Pennsylvania's
obligations could still be characterized as providing upper medium grade
security, with a strong capacity for timely repayment of debt.

   Factors contributing positively to credit quality in Pennsylvania include 
a favorable debt structure, a diversifying economic base, and conservatively 
managed financial operations on the part of state government. Tax-supported 
debt is only slightly above average state levels on a per capita basis and as 
a percent of state personal income. Over the past two decades, this debt 
burden has improved considerably in Pennsylvania, and debt continues to be 
rapidly retired, while state borrowing plans are modest. 

   In the past twenty years, Pennsylvania's economy has undergone a healthy, 
though traumatic, transformation. Manufacturing employment has declined from 
35% of total state employment in 1970 to 18.2% of total employment in 1994, 
only slightly above the U.S. average. Growth in service sector jobs offset 
the loss of manufacturing jobs, and Pennsylvania's economy is now much more 
closely aligned with the national economy. In the future, economic booms and 
busts should be milder than in the past and more closely follow national 
averages. The positive change in the economy has not been without costs. 
Growth levels in employment, population and personal income lagged behind 
U.S. averages in the 1980s. During this period, per capita personal income 
slipped to about the U.S. average. Many communities dominated by a single 
industry were particularly hurt, and recent growth in the state economy has 
bypassed much of the state outside of the immediate Philadelphia and 
Pittsburgh metropolitan areas. As a result, the credit quality of these areas 
is often marginal. 

   During the 1991-1992 national economic recession, Pennsylvania fared a bit 
worse than the U.S. average but better than many neighboring Northeastern and 
Mid-Atlantic states. Led by continuing declines in manufacturing, employment 
decreased about 4%, or double the U.S. loss rate. Pennsylvania has 
subsequently experienced economic recovery in line with the U.S. 

   Fiscally, Pennsylvania has historically maintained balanced budgets, a 
result of sound and conservative budgeting policies. During the period of 
economic growth in the late 1980s, operating surpluses were recorded, and a 
"rainy day" fund was established. The recent recession tested these policies, 
but the Commonwealth emerged from the recession with its finances and credit 
quality intact. In 1990 and 1991, as the recession worsened, budget balances 
were eliminated, and the state ended 1991 in a deficit position. However, a 
combination of expenditure restraint and broad-based tax increases enabled 
the state to end 1992 with a surplus. Finances are now stable and healthy. 

   The risk factors in Pennsylvania's credit quality may be summarized as 
slow growth, an aging population, average income, and a continuing challenge 
to maintain balanced budgets. In addition, a number of local governments in 
the Commonwealth, most notably Philadelphia, face continuing fiscal stress, 
and are unable to address serious economic, social and healthcare problems 
within revenue constraints. Philadelphia's credit prospects have recently 
improved but remain a challenge to the credit quality of Pennsylvania. 


                            YIELD AND TOTAL RETURN 

   The yield of the Pennsylvania Insured Long-Term Portfolio for the 30-day 
period ended November 30, 1995 was +5.09%. Yield is calculated daily and 
premium and discounts on asset-backed securities are not amortized. 

   The average annual total return of the Pennsylvania Insured Long-Term 
Portfolio for the one-year and five-year period ending November 30, 1995 and
since its inception on April 7, 1986 was +18.48%, +8.95% and +8.28%,
respectively. The average total return of the Pennsylvania Money Market
Portfolio for the one-year and five-year period ending November 30, 1995 and
since its inception on June 13, 1988 was +3.69%, +3.24% and +4.15%,

respectively. Total return is computed by determining the average compounded
rates of return over the period set forth above that would equate an initial
amount invested at the beginning of the period to the ending redeemable value of
the investment.



                             CALCULATION OF YIELD 

   The current yield of the Pennsylvania Money Market Portfolio is calculated 
daily on a base period return of a hypothetical account having a beginning 
balance of one share for a particular period of time (generally 7 days). The 
return is determined by dividing the net change (exclusive of any capital 
changes) in such account by its average net assets value for the period, and 
then multiplying it by 365/7 to get the annualized current yield. The 
calculation of net change reflects the value of additional shares purchased 
with the dividends by the Portfolio, including dividends on both the original 
share and on such additional shares. An effective yield, which reflects the 
effects of compounding and represents an annualization of the current yield 
with all dividends reinvested, may also be calculated for the Portfolio by 
adding 1 to the net change, raising the sum to the 365/7 power, and 
subtracting 1 from the result. 

   Set forth below is an example, for purposes of illustration only, of the 
current and effective yield calculations for the Pennsylvania Money Market 
Portfolio for the 7-day base period ended November 30, 1995.

   The Pennsylvania Money Market Portfolio seeks to maintain, but does not
guarantee, a constant net asset value of $1.00. The yield of the Portfolio will
fluctuate. The Money Market Portfolio seeks to maintain, but does not guarantee,
a constant net asset value of $1.00 per share. Although the Money Market
Portfolio invests in high-quality instruments, the shares of the Portfolio are
not insured or guaranteed by the U.S. Government. The annualization of a week's
dividend is not a representation by the Portfolio as to what an investment in
the Portfolio will actually yield in the future. Actual yields will depend on
such variables as investment quality, average maturity, the type of instruments
the Portfolio invests in, changes in interest rates on instruments, changes in
the expenses of the Fund and other factors. Yields are one basis investors may
use to analyze the Portfolios of the Fund, and other investment vehicles,
however, yields of other investment vehicles may not be comparable because of
the factors set forth in the preceding sentence, differences in the time periods
compared, and differences in the methods used in valuing portfolio instruments,
computing net asset value and calculating yield.

                            INVESTMENT MANAGEMENT 

   The Fund receives all investment advisory services on an "internalized," 
at-cost basis from an experienced investment management staff employed 
directly by The Vanguard Group, Inc. ("Vanguard"), a subsidiary jointly-owned 
by the Fund and the other funds in The Vanguard Group of Investment 
Companies. The investment management staff is supervised by the senior 
officers of the Fund. 

   The investment management staff is responsible for: maintaining the 
specified standards; making changes in specific issues in light of changes in 
the fundamental basis for purchasing such securities; and adjusting the Fund 
to meet cash inflow (or outflow), which reflects net purchases and exchanges 
of shares by investors (or net redemptions of shares) and reinvestment of the 
Fund's income. 

   A change in securities held by the Fund is known as "portfolio turnover" 
and may involve the payment by the Fund of dealer mark-ups, underwriting 
commissions and other transaction costs on the sales of securities as well as 
on the reinvestment of the proceeds in other securities. The annual portfolio 
turnover rate for each of the Fund's Portfolios is set forth under the 
heading "Financial Highlights" in the prospectus. The portfolio turnover rate 
is not a limiting factor when management deems it desirable to sell or 
purchase securities. It is impossible to predict whether or not the portfolio 
turnover rate in future years will vary significantly from the rates in 
recent years. 
   
   During the fiscal years ended November 30, 1993, 1994 and 1995, the Fund did
not pay any brokerage commissions.
    

                              PURCHASE OF SHARES 

   The Fund reserves the right in its sole discretion (i) to suspend the 
offering of its shares, (ii) to reject purchase orders when in the judgment 
of management such rejection is in the best interest of the Fund, and (iii) 
to reduce or waive the minimum investment for or any other restrictions on 
initial and subsequent investments under circumstances where certain 
economies, can be achieved in sales of the Fund's shares. 


   Stock Certificates.  Your purchase will be made in full and fractional 
shares of the Fund calculated to three decimal places. Shares are normally 
held on deposit for shareholders by the Fund, which will send to shareholders 
a statement of shares owned at the time of each transaction. This saves the 
shareholders the trouble of safekeeping the certificates and saves the Fund 

                                                                             B-9
<PAGE>

the cost of issuing certificates. Share certificates for the Pennsylvania
Insured Long-Term Portfolio are, of course, available at any time upon written
request at no additional cost to shareholders. No certificates will be issued
for fractional shares or shares of the Pennsylvania Money Market Portfolio.


                             REDEMPTION OF SHARES 

   The Fund may suspend redemption privileges or postpone the date of payment 
(i) during any period that the New York Stock Exchange is closed, or trading 
on the Exchange is restricted as determined by the Securities and Exchange 
Commission (the "Commission"), (ii) during any period when an emergency 
exists as defined by the rules of the Commission as a result of which it is 
not reasonably practicable for the Fund to dispose of securities owned by it, 
or fairly to determine the value of its assets, and (iii) for such other 
periods as the Commission may permit. 

   If the Board of Trustees determines that it would be detrimental to the 
best interests of the remaining shareholders of the Fund to make payment 
wholly or partly in cash, the Fund may pay the redemption price in whole or 
in part by a distribution in kind of securities held by the Fund in lieu of 
cash in conformity with applicable rules of the Commission. Investors may 
incur brokerage charges on the sale of such securities so received in payment 
of redemptions. 

   No charge is made by the Fund for redemptions except for wire redemptions 
of under $5,000 which may be charged a maximum fee of $5.00. Any redemption 
may be more or less than the shareholder's cost depending on the market value 
of the securities held by the Fund. 

   Signature Guarantees.  To protect your account, the Fund and Vanguard from 
fraud, signature guarantees are required for certain redemptions. Signature 
guarantees enable the Fund to verify the identity of the person who has 
authorized a redemption from your account. Signature guarantees are required 
in connection with: (1) all redemptions, regardless of the amount involved, 
when the proceeds are to be paid to someone other than the registered owners; 
and (2) share transfer requests. 

   A signature guarantee may be obtained from banks, brokers and any other 
guarantor institution that Vanguard deems acceptable. Notaries public are not 
acceptable guarantors. 

   The signature guarantees must appear either: (1) on the written request 
for redemption, (2) on a separate instrument for assignment ("stock power") 
which should specify the total number of shares to be redeemed, or (3) on all 
stock certificates tendered for redemption and, if shares held by the Fund 
are also being redeemed, on the letter or stock power. 


                             VALUATION OF SHARES 

   The valuation of shares of the Pennsylvania Insured Long-Term Portfolio is 
described in detail in the Prospectus. 


   Pennsylvania Money Market Portfolio.  The net asset value per share of the 
Pennsylvania Money Market Portfolio is determined on each day that the New 
York Stock Exchange is open. 

   It is the policy of the Pennsylvania Money Market Portfolio to attempt to 
maintain a net asset value of $1.00 per share for purposes of sales and 
redemptions. The Portfolio seeks to maintain, but does not guarantee, a 
constant net asset value of $1.00 per share. Although the Pennsylvania Money 
Market Portfolio invests in high-quality instruments, the shares of the 
Portfolio are not insured or guaranteed by the U.S. Government. The 
instruments held by the Pennsylvania Money Market Portfolio are valued on the 
basis of amortized cost which does not take into account unrealized capital 
gains or losses. This involves valuing an instrument at-cost and thereafter 
assuming a constant amortization to maturity of any discount or premium, 
regardless of the impact of fluctuating interest rates on the market value of 
the instrument. While this method provides certainty in valuation, it may 
result in periods during which value, as determined by amortized cost, is 
higher or lower than the price the Portfolio would receive if it sold the

B-10
<PAGE>

instrument. During periods of declining interest rates, the daily yield on
shares of the Portfolio computed as described above may tend to be higher than a
like computation made by a fund with identical investments utilizing a method of
valuation based upon market prices and estimates of market prices for all of its
portfolio instruments. Thus, if the use of amortized cost of the Portfolio
resulted in a lower aggregate portfolio value on a particular day, a prospective
investor in the Portfolio would be able to obtain a somewhat higher yield than
would result from investment in a fund utilizing solely market values, and
existing investors in the Portfolio would receive less investment income. The
converse would apply in a period of rising interest rates.

   The valuation of the Pennsylvania Money Market Portfolio's instruments 
based upon their amortized cost and the commitment to maintain the 
Portfolio's per share net asset value of $1.00 is permitted by Rule 2a-7 
under the Investment Company Act of 1940 pursuant to which the Fund must 
adhere to certain conditions. Accordingly, the Fund has agreed to maintain a 
dollar-weighted average portfolio maturity for the Pennsylvania Money Market 
Portfolio of 90 days or less, to purchase instruments having remaining 
maturities of thirteen months or less only, and to invest only in securities 
determined by the Board of Trustees to be of good quality with minimal credit 
risks. 

   It is a fundamental objective of management to maintain the Portfolio's 
price per share as computed for the purpose of sales and redemptions at 
$1.00. The Trustees have established procedures designed to achieve this 
objective. Such procedures will include a review of the Portfolio's holdings 
by the Trustees, at such intervals as they may deem appropriate, to determine 
whether the Portfolio's net asset value calculated by using available market 
quotations deviates from $1.00 per share based on amortized cost. The extent 
of any deviation will be examined by the Trustees. If such deviation exceeds 
1/2 of 1%, the Trustees will promptly consider what action, if any, will be 
initiated. In the event the Trustees determine that a deviation exists which 
may result in material dilution or other unfair results to investors or 
existing shareholders, they have agreed to take such corrective action as 
they regard as necessary and appropriate, including the sale of portfolio 
instruments prior to maturity to realize capital gains or losses or to 
shorten average portfolio maturity; withholding dividends; making a special 
capital distribution; redemptions of shares in kind; or establishing a net 
asset value per share by using available market quotations. 

                                                                            B-11

THE VANGUARD GROUP 

   Vanguard Pennsylvania Tax-Free Fund is a member of The Vanguard Group of 
Investment Companies. Through their jointly-owned subsidiary, The Vanguard 
Group, Inc. ("Vanguard"), the Fund and the other Funds in the Group obtain 
at-cost virtually all of their corporate management, administrative and 
distribution services. Vanguard also provides investment advisory services on 
an at-cost basis to several of the Vanguard Funds, including the Vanguard 
Pennsylvania Tax-Free Fund. 

B-12
<PAGE>

   Vanguard employs a supporting staff of management and administrative 
personnel needed to provide the requisite services to the Funds and also 
furnishes the Funds with necessary office space, furnishings and equipment. 
Each Fund pays its share of Vanguard's net expenses which are allocated among 
the Funds under methods approved by the Board of Trustees (Directors) of each 
Fund. In addition, each Fund bears its own direct expenses such as legal, 
auditing and custodian fees. In order to generate additional revenues for 
Vanguard and thereby reduce the Funds' expenses, Vanguard also provides 
certain administrative services to other organizations. 

   The Fund's Officers are also officers and employees of Vanguard. No 
officer or employee owns, or is permitted to own, any securities of any 
external adviser for the Funds. 

   The Vanguard Group adheres to a Code of Ethics established pursuant to 
Rule 17j-1 under the Investment Company Act of 1940. The Code is designed to 
prevent unlawful practices in connection with the purchase or sale of 
securities by persons associated with Vanguard. Under Vanguard's Code of 
Ethics, certain officers and employees of Vanguard who are considered access 
persons are permitted to engage in personal securities transactions. However, 
such transactions are subject to procedures and guidelines substantially 
similar to those recommended by the mutual fund industry and approved by the 
U.S. Securities and Exchange Commission. 

   The Vanguard Group, Inc. ("Vanguard") was established and operates under a 
Funds' Service Agreement which was approved by the shareholders of each of 
the Funds in 1992. The amounts which each of the Funds has invested are 
adjusted from time to time in order to maintain the proportionate 
relationship between each Fund's relative net assets and its contribution to 
Vanguard's capital. At November 30, 1995 Vanguard Pennsylvania Tax-Free Fund 
had contributed capital of $329,000 to Vanguard representing 1.6% of 
Vanguard's capitalization. The Funds' Service Agreement provides as follows: 
(a) each Vanguard Fund may invest up to 0.40% of its current net assets in 
Vanguard, and (b) there is no other limitation on the amount that each 
Vanguard Fund may contribute to Vanguard's capitalization. 

   Management.  Corporate management and administrative services include: (1) 
executive staff; (2) accounting and financial; (3) legal and regulatory; (4) 
shareholder account maintenance; (5) monitoring and control of custodian 
relationships; (6) shareholder reporting; and (7) review and evaluation of 
advisory and other services provided to the Funds by third parties. During 
the fiscal year ended November 30, 1995, the Funds share of Vanguard's actual 
net costs of operations relating to management and administrative services 
(including transfer agency) totaled approximately $4,077,000. 

   Distribution.  Vanguard provides all distribution and marketing activities 
for the Funds in the Group. Vanguard Marketing Corporation, a wholly-owned 
subsidiary of The Vanguard Group, Inc. acts as Sales Agent for shares of the 
Funds, in connection with any sales made directly to investors in the states 
of Florida, Missouri, New York, Ohio, Texas and such other states as it may 
be required. 

   The principal distribution expenses are for advertising, promotional 
materials and marketing personnel. Distribution services may also include 
organizing and offering to the public, from time to time, one or more new 
investment companies which will become members of the Group. The Trustees 
(Directors) and officers of Vanguard determine the amount to be spent 
annually on distribution activities, the manner and amount to be spent on 
each Fund, and whether to organize new investment companies. 


   One half of the distribution expenses of a marketing and promotional 
nature is allocated among the Funds based upon their relative net assets. The 
remaining one half of these expenses is allocated among the Funds based upon 
each Fund's sales for the preceding 24 months relative to the total sales of 
the Funds as a Group, provided, however, that no Fund's aggregate quarterly 
rate of contribution for distribution expenses of a marketing and promotional 
nature shall exceed 125% of the average distribution expense rate for the 
Group, and that no Fund shall incur annual distribution expenses in excess of 
20/100 of 1% of its average month-end net assets. During the year ended 
November 30, 1995 the Fund paid approximately $611,000 of the Group's 
distribution and marketing expenses. 

                                                                            B-13

   Investment Advisory Services.  Vanguard also provides investment advisory 
services to the Fund; Vanguard Municipal Bond Fund; Vanguard Money Market 
Reserves; Vanguard Admiral Funds; the several Portfolios of Vanguard Fixed 
Income Securities Fund; Vanguard Institutional Index Fund; Vanguard Bond 
Index Fund; the Vanguard California Tax-Free Fund; Vanguard Florida Insured 
Tax-Free Fund; Vanguard New Jersey Tax-Free Fund; Vanguard New York Insured 
Tax-Free Fund; Vanguard Ohio Tax-Free Fund; Vanguard Balanced Index Fund; 
Vanguard Index Trust; Vanguard International Equity Index Fund; Vanguard 
Tax-Managed Fund; the Aggressive Growth Portfolio of Vanguard Horizon Fund; 
several Portfolios of Vanguard Variable Insurance Fund; a portion of 
Vanguard/Windsor II; a portion of Vanguard/Morgan Growth Fund as well as 
several indexed separate accounts. These services are provided on an at-cost 
basis from a money management staff employed directly by Vanguard. The 
compensation and other expenses of this staff are paid by the Funds utilizing 
these services. During the years ended November 30, 1993, 1994 and 1995 the 
Fund paid approximately $204,000, $281,000, and $339,000 of Vanguard's 
investment advisory expenses. 
   
   Remuneration of Trustees and Officers.  The Fund pays each Trustee, who is 
not also an Officer, an annual fee plus travel and other expenses incurred in 
attending Board meetings. During the year ended November 30, 1995 the Fund 
paid $9,000 in Trustees' expenses. The Fund's Officers and employees are paid 
by Vanguard which, in turn, is reimbursed by the Fund, and each other Fund in 
the Group, for its proportionate share of Officers' and employees' salaries 
and retirement benefits. During the year ended November 30, 1995, the Fund's 
proportionate share of remuneration paid to all Officers of the Fund, as a 
group, was approximately $88,292. 

   Trustees who are not Officers are paid an annual fee based on the number 
of years of service on the Board upon retirement. The fee is equal to $1,000 
for each year of service (up to fifteen years) and each investment Company 
member of the Vanguard Group contributes a proportionate amount to this fee 
based on its relative net assets. Under its Retirement Plan, Vanguard 
contributes annually an amount equal to 10% of each eligible officer's annual 
compensation plus 5.7% of that part of an eligible officer's compensation 
during the year, if any, that exceeds the Social Security Taxable Wage Base 
then in effect. Under its Thrift Plan, all eligible Officers are permitted to 
make pre-tax contributions in an amount up to 4% of total compensation, 
subject to federal tax limitations, which are matched by Vanguard on a 100% 
basis. The Fund's proportionate share of retirement contributions made by 
Vanguard under its Retirement and Thrift Plans on behalf of all Officers of 
the Fund, as a group, during the 1995 fiscal year was approximately $2,400. 
    
   The following table provides detailed information with respect to the 
amounts paid or accrued for the Trustees for the fiscal year ended November 
30, 1995.

                   DESCRIPTION OF SHARES AND VOTING RIGHTS 

   The Fund was organized as a Pennsylvania Trust on January 15, 1986. 

   The Declaration of Trust permits the Trustees to issue an unlimited number 
of shares of beneficial interest, without par value, from an unlimited number 
of separate classes ("Portfolios") of shares. Currently, the Fund is offering 
shares of two Portfolios. 

   The shares of the Fund are fully paid and nonassessable, except as set 
forth under "Shareholder and Trustee Liability," and have no preference as to 
conversion, exchange, dividends, retirement or other features. The shares of 
the Fund have no pre-emptive rights. The shares of the Fund have non- 
cumulative voting rights, which means that the holders of more than 50% of 
the shares voting for the election of Trustees can elect 100% of the Trustees 
if they choose to do so. A shareholder is entitled to one vote for each full 
share held (and a fractional vote for each fractional share held), then 
standing in his name on the books of the Fund. On any matter submitted to a 
vote of shareholders, all shares of the Fund then issued and outstanding and 
entitled to vote, irrespective of the class, shall be voted in the aggregate 
and not by class: except (i) when required by the Investment Company Act of 
1940, shares shall be voted by individual class; and (ii) when the matter 
does not affect any interest of a particular class, then only shareholders of 
the affected class or classes shall be entitled to vote thereon. 

   The Fund will continue without limitation of time, provided, however that: 

     1) Subject to the majority vote of the holders of shares of the Fund 
        outstanding, the Trustees may sell or convert the assets of the Fund 
        to another investment company in exchange for shares of such 
        investment company, and distribute such shares, ratably among the 
        shareholders of the Fund. 

     2) Subject to the majority vote of shares of the Fund outstanding, the 
        Trustees may sell and convert into money to the assets of the Fund 
        and distribute such assets ratably among the shareholders of the 
        Fund; and 

   Upon completion of the distribution of the remaining assets of any 
Portfolio as provided in paragraphs 1) and 2) above the Fund shall terminate 
and the Trustees shall be discharged of any and all further liabilities and 
duties hereunder and the right, title and interest of all parties shall be 
cancelled and discharged. 

   Shareholder and Trustee Liability.  Under Pennsylvania law, shareholders of 
such a Trust may under certain circumstances, be held personally liable as 
partners for the obligations of the Fund. Therefore, the Declaration of Trust 
contains an express disclaimer of shareholder liability for acts or 
obligations of the Fund and requires that notice of such disclaimer be given 
in each agreement, obligation, or instrument entered into or executed by the 
Fund or the Trustees. The Declaration of Trust provides for indemnification 
out of the Fund property of any shareholder held personally liable for the 
obligations of the Fund. The Declaration of Trust also provides that the Fund 
shall, upon request, assume the defense of any claim made against any 
shareholder for any act or obligation of the Fund and satisfy any judgment 
thereon. Thus, the risk of a shareholder incurring financial loss on account 
of shareholder liability is limited to circustances in which the Fund itself 
would be unable to meet its obligations. 

   The Declaration of Trust further provides that the Trustees will not be 
liable for errors of judgment or mistakes of fact or law, but nothing in the 
Declaration of Trust protects a Trustee against any liability to which he 
would otherwise be subject by reason of willful misfeasance, bad faith, gross 
negligence, or reckless disregard of the duties involved in the conduct of 
his office.

         APPENDIX A--DESCRIPTION OF MUNICIPAL BONDS AND THEIR RATINGS 

   Municipal Bonds--General.  Municipal Bonds generally include debt 
obligations issued by states and their political subdivisions, and duly 
constituted authorities, not-for-profit corporations, and corporations, to 
obtain funds to construct, repair or improve various public facilities such 
as airports, bridges, highways, hospitals, housing, schools, streets and 
water and sewer works. Municipal Bonds may also be issued to refinance 
outstanding obligations as well as to obtain funds for general operating 
expenses and for loan to other public institutions and facilities. 

   The two principal classifications of Municipal Bonds are "general 
obligation" and "revenue" or "special tax" bonds. General obligation bonds 
are secured by the issuer's pledge of its full faith, credit and taxing power 
for the payment of principal and interest. Revenue or special tax bonds are 
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 or other 
tax, but not from general tax revenues. The Fund may also invest in 
tax-exempt industrial development bonds, short-term municipal obligations 
(rated SP-1+ of SP-1 by Standard & Poor's Corp. or MIG by Moody's Investors 
Service), project notes, demand notes and tax- exempt commercial papers 
(rated A-1 by Standard & Poor's Corp. or P-1 by Moody's Investors Service). 

   Industrial revenue bonds in most cases are revenue bonds and generally do 
not have the pledge of the credit of the issuer. The payment of the principal 
and interest on such industrial revenue bonds is dependent solely on the 
ability of the user of the facilities 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. Short-term municipal obligations 
issued by states, cities, municipalities or municipal agencies, include Tax 
Anticipation Notes, Revenue Anticipation Notes, Bond Anticipation Notes, 
Construction Loan Notes and Short-Term Discount Notes. Project Notes are 
instruments issued by the Department of Housing and Urban Development but 
issued by a state or local housing agency. While the issuing agency has the 
primary obligation on such Project notes, they are also secured by the full 
faith and credit of the United States. 

   Note obligations with demand or put options may have a stated maturity in 
excess of one year, but permit any holder to demand payment of principal plus 
accrued interest upon a specified number of days' notice. Frequently, such 
obligations are secured by letters of credit or other credit support 
arrangements provided by banks. The issuer of such notes normally has a 
corresponding right, after a given period, to repay in its discretion the 
outstanding principal of the note plus accrued interest upon a specific 
number of days' notice to the bondholders. The interest rate on a demand note 
may be based upon a known lending rate, such as a bank's prime rate, and be 
adjusted when such rate changes, or the interest rate on a demand note may be 
a market rate that is adjusted at specified intervals. The demand notes in 
which the Fund will invest are payable on not more than one year's notice. 
Each note purchased by the Fund will meet the quality criteria set out above 
for the Fund. 

   The yields of Municipal Bonds depend on, among other things, general money 
market conditions conditions in the Municipal Bond market, the size of a 
particular offering, the maturity of the obligation, and the rating of the 
issue. The ratings of Moody's Investors Service, Inc. and Standard & Poor's 
Corporation represent their opinions of the quality of the Municipal Bonds 
rated by them. It should be emphasized that such ratings are general and are 
not absolute standards of quality. Consequently, Municipal Bonds with the 
same maturity, coupon and rating may have different yields, while Municipal 
Bonds of the same maturity and coupon, but with different ratings may have 
the same yield. It will be the responsibility of the investment management 
staff to appraise independently the fundamental quality of the bonds held by 
the Fund. 

   Municipal Bonds are sometimes purchased on a "when issued" basis meaning 
the Fund has committed to purchasing certain specified securities at an 
agreed upon price when they are issued. The period between commitment date 
and issuance date can be a month or more. It is possible that the securities 
will never be issued and the commitment canceled. 

   From time to time proposals have been introduced before Congress to 
restrict or eliminate the Federal income tax exemption for interest on 
Municipal Bonds. Similar proposals may be introduced in the future. If any such

B-16
<PAGE>

proposal were enacted, it might restrict or eliminate the ability of the Fund to
achieve its investment objective. In that event, the Fund's Trustees and
Officers would reevaluate its investment objective and policies and consider
recommending to its shareholders changes in such objective and policies.

   Similarly, from time to time proposals have been introduced before State 
and local legislatures to restrict or eliminate the State and local income 
tax exemption for interest on Municipal Bonds. Similar proposals may be 
introduced in the future. If any such proposal were enacted, it might 
restrict or eliminate the ability of each Portfolio to achieve its respective 
investment objective. In that event, the Fund's Trustees and Officers would 
reevaluate its investment objective and policies and consider recommending to 
its shareholders changes in such objective and policies. (For more 
information please refer to "Risk Factors" on page B-6.) 

   Ratings.  Excerpts from Moody's Investors Service, Inc.'s Municipal Bond 
ratings; Aaa--judged to be of the "best quality" and are referred to as "gilt 
edge"; interest payments are protected by a large or by an exceptionally 
stable margin and principal is secure; Aa--judged to be of "high quality by 
all standards" but as to which margins of protection or other elements make 
long-term risks appear somewhat larger than Aaa-rated Municipal Bonds; 
together with Aaa group they comprise what are generally known as "high grade 
bonds"; A--possess many favorable investment attributes and are considered 
"upper medium grade obligations." Factors giving security to principal and 
interest of A-rated Municipal Bonds are considered adequate, but elements may 
be present which suggest a susceptibility to impairment sometime in the 
future; Baa--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; Ba--protection of principal and interest payments may be very moderate; 
judged to have speculative elements; their future cannot be considered as 
well-assured; B--lack characteristics of a desirable investment; assurance of 
interest and principal payments over any long period of time may be small; 
Caa--poor standing; may be in default or there may be present elements of 
danger with respect to principal and interest; Ca--speculative in a high 
degree; often in default; C--lowest rated class of bonds; issues so rated can 
be regarded as having extremely poor prospects for ever attaining any real 
investment standing. 

   Description of Moody's ratings of state and municipal notes: Moody's 
ratings for state and municipal notes and other short-term obligations are 
designated Moody's Investment Grade ("MIG"). Symbols used will be as follows: 
MIG-1--Best quality, enjoying strong protection from established cash flows 
of funds for their servicing or from established and broad-based access to 
the market for refinancing, or both; MIG-2--High quality with margins of 
protection ample although not so large as in the preceding group. 

   Description of Moody's highest commercial paper rating. Prime-1 
("P-1)--Judged to be of the best quality. Their short-term debt obligations 
carry the smallest degree of investment risk. 

   Excerpts from Standard & Poor's Corporation's Municipal Bond ratings: 
AAA--has the highest rating assigned by S&P; extremely strong capacity to pay 
principal and interest; AA--has a very strong capacity to pay interest and 
repay principal and differs from the higher rated issues only in a small 
degree; A--has a strong capacity to pay principal and interest, although 
somewhat more susceptible to the adverse changes in circumstances and 
economic conditions; BBB--regarded as having an adequate capacity to pay 
principal and interest; normally exhibit adequate protection parameters but 
adverse economic conditions or changing circumstances are more likely to lead 
to a weakened capacity to pay principal and interest than for bonds in A 
category; BB--B--CCC--CC--predominantly speculative with respect to capacity 
to pay interest and repay principal in accordance with terms of obligation; 
BB is being paid; D--in default, and payment of principal and/or interest is 
in arrears. 

   The ratings from "AA" to "B" may be modified by the addition of a plus or 
minus sign to show relative standing within the major rating categories. 

   Excerpt from Standard & Poor's Corporation's rating of municipal note 
issues: SP-1+ --very strong capacity to pay principal and interest; 
SP-1--strong capacity to pay principal and interest. 

                                                                            B-17
<PAGE>

   Description of S&P's highest commercial papers ratings: A-1+ --This 
designation indicates the degree of safety regarding timely payment is 
overwhelming. A-1--This designation indicates the degree of safety regarding 
timely payment is very strong. 


                   APPENDIX B--MUNICIPAL LEASE OBLIGATIONS 

   Each Portfolio may invest in municipal lease obligations. Such securities 
will be treated as liquid under the following guidelines which have been 
established by the Board of Trustees. 


     1. The obligation has been rated "investment grade" by at least one 
   NRSRO and is considered to be investment grade by the investment adviser. 


     2. The obligation is secured by payments from a governmental lessee 
   which is generally recognized and has debt obligations which are actively 
   traded by a minimum of five broker/dealers. 

     3. At least $25 million of the lessee debt is outstanding either in a 
   single transaction or on parity, and owned by a minimum of five 
   institutional investors. 

     4. The investment adviser has determined that the obligation, or a 
   comparable lessee security, trades in the institutional marketplace at 
   least periodically, with a bid/offer spread of 20 basis points or less. 

     5. The governmental lessee has a full faith and credit general 
   obligation rating of at least "A-" as published by at least one NRSRO or 
   as determined by the investment adviser. If the lessee is a state 
   government, the general obligation rating must be at least BAA1, BBB+, or 
   equivalent, as determined above. 

     6. The projects to be financed by the obligation are determined to be 
   critical to the lessee's ability to deliver essential services. 

     7. Specific legal features such as covenants to maintain the tax-exempt 
   status of the obligation, covenants to make lease payments without the 
   right of offset or counterclaim, covenants to return leased property to 
   the lessor in the event of non-appropriation, insurance policies, debt 
   service reserve fund, are present. 

     8. The lease must be "triple net" (i.e., lease payments are net of 
   property maintenance, taxes and insurance). 

     9. If the lessor is a private entity, there must be a sale and absolute 
   assignment of rental payments to the trustee, accompanied by a legal 
   opinion from recognized bond counsel that lease payments would not be 
   considered property of the lessor's estate in the event of lessor's 
   bankruptcy.
