INVESTMENT 
OBJECTIVE &
POLICIES            Vanguard Florida Insured Tax-Free Fund (the "Fund") is an
                    open-end, non-diversified investment company that seeks to
                    provide income that is exempt from federal personal income
                    taxes. It is also expected that the Fund's shares will be
                    exempt from the Florida intangible personal property tax.
                    The Fund will invest primarily in securities issued by
                    municipal Florida state and local governments and public
                    financing authorities, but may also invest in securities of
                    issuers other than Florida and its political subdivisions.
                    The Fund is available only to Florida residents. Although
                    the Fund invests in high quality instruments, the shares of
                    the Fund are not insured or guaranteed by the U.S.
                    Government.

                    return. Both yield and total return figures are based on
                    historical earnings and are not intended to indicate future
                    performance. The "total return" of the Fund refers to the
                    average annual compounded rates of return over one-, five-
                    and ten-year periods or over the life of the Fund (as stated
                    in the advertisement) that would equate 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 Fund 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 Fund'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.
                    Methods used to calculate advertised yields are standardized
                    for all bond mutual funds. However, these methods differ
                    from the accounting methods used by the Fund to maintain its
                    books and records, and so the advertised 30-day yield may
                    not fully reflect the income paid to an investor's account
                    or the yield reported in the Fund's financial statements.

OBJECTIVE           The Fund is an open-end, non-diversified investment company.
                    The objective of the Fund is to provide investors with a    
The Fund seeks      high level of income that is exempt from federal personal   
to provide          income taxes. The Fund is also designed to provide an       
income exempt       investment that is exempt from the Florida intangible       
from federal        personal property tax.                                      
income taxes                                                                    
                    The Fund is available only to investors who reside in       
                    Florida. There is no assurance that the Fund will achieve   
                    its stated objective.                                       
                                                                                
                    The investment objective of the Fund is fundamental and so  
                    cannot be changed without the approval of a majority of the 
                    Fund's shareholders.

INVESTMENT
POLICIES            The Fund will invest at least 80% of its net assets in      
                    insured Florida municipal securities, exclusive of Florida  
The Fund invests    AMT bonds (see page 5). Florida municipal securities are
in insured Florida  debt obligations issued by Florida state and local
municipal           governments and public financing authorities (and by certain
securities exempt   U.S. territories) that seeks to provide interest income that
from the Florida    is exempt from federal personal income taxes. The Florida
intangible tax      municipal securities described above, may include securities
                    in which the tax-exempt interest rate is determined by an
                    index, swap or some other formula. Insured Florida municipal
                    securities are those in which scheduled payments of interest
                    and principal are guaranteed by a private (non-governmental)
                    insurance company.
    
                                                                                
                    The insurance feature of the Fund does not guarantee the    
                    market value of the municipal bonds or the value of the     
                    Fund's shares. The insurance refers to the face or par value
                    of the securities in the Fund. See "Implementation of       
                    Policies" for a description of the Fund's insurance feature.
                                                                                
                    Under normal circumstances, the Fund will only invest in    
                    insured Florida municipal securities and other investments  
                    (such as certain short-term cash investments) that are      
                    exempt from the Florida intangible personal property tax.   
                    Thus, it is expected that the Fund's shares will be exempt  
                    from the Florida intangible tax for Florida residents. See  
                    "Dividends, Capital Gains and Taxes" for more information.  
                                                                                
                    The Fund is expected to maintain a dollar-weighted 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 Fund seeks to invest substantially all of its 
                    assets in insured Florida municipal obligations. However,   
                    under certain circumstances, the Fund may invest up to 20%  
                    of its assets in any combination of the following           
                    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 Municipal securities of non-Florida issuers;              
                                                                                
                    o Uninsured, short-term municipal securities issued in      
                      Florida or in other states;

                    o Certain taxable 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 Fund.

                    In such cases, a portion of the Fund's income may be subject
                    to federal income taxes, and all or a portion of the Fund's
                    assets may be subject to the Florida intangible personal
                    property tax, or both. The imposition of the Florida
                    intangible personal property tax would occur only if the
                    Fund held such securities on the last day of the year, and
                    it is the intention of the Fund's adviser to avoid such a
                    situation. (See page 16).


                    Subject to the same 20% limit, the Fund is also authorized
                    to invest in Florida AMT bonds. The income from Florida AMT
                    bonds is exempt from federal income taxes but is a tax
                    preference item for purposes of the federal AMT. Although
                    authorized to invest in AMT bonds, the Fund has no present
                    intention to do so.

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

The Fund will
diversify its
holdings            Although organized as a non-diversified investment company,
                    the Fund intends to diversify its holdings of Florida
                    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 the
                    Fund's assets be limited in aggregate to 50% of the Fund,
                    and that no one issue exceeds 25% of the Fund's total
                    assets. As of November 30, 1995, the Fund held securities of
                    56 issuers, with the largest holding representing 4.0% of
                    the Fund's assets. As of November 30, 1995 the Fund's top
                    ten holdings, based on market value, represented 26.9% of
                    its net assets.

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

                    The Fund's policy of investing at least 80% of its assets in
                    Florida municipal securities under normal circumstances is
                    fundamental and may not be changed without shareholder
                    approval. The other investment policies described above are
                    not fundamental and so may be changed by the Board of
                    Trustees without shareholder approval. However, shareholders
                    would be notified of any material change in the Fund's
                    policies.

RISKS               As a mutual fund investing in long-term municipal

subject to
interest rate,      Interest rate risk is the potential for bond price 
credit, call,       fluctuations due to changing interest rates. In general,   
and income risk     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 factors, including credit quality, being equal.
                    Interest rate risk may be increased or decreased when a
                    portfolio purchases derivative Florida 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 fund.
                    The credit risk of a fund depends on the credit quality of
                    its underlying securities. In general, the lower the credit
                    quality of a fund's municipal securities, the higher a
                    fund'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 fund will be required
                    to invest the unanticipated proceeds at lower interest
                    rates, and the fund'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 fund's
                    income due to falling market interest rates. Because a
                    fund's income is based on interest rates, which can
                    fluctuate substantially over short periods, income risk is
                    expected to vary from fund to fund.

The Fund is subject
to manager risk     Finally, the investment adviser manages the Fund 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 the Fund's investment strategy effectively. As a
                    result, the Fund may fail to achieve its stated objective.
               

                    Because the Fund invests in long-term municipal bonds,
                    interest rate risk for the Fund may be high. The average
                    weighted maturity of the Fund is expected to exceed 15
                    years, meaning that the Fund's share price will fluctuate,
                    sometimes substantially, when interest rates change. The
                    following chart illustrates the potential interest rate risk
                    of the Fund. The chart shows the market value of a $1,000
                    investment in a single bond with the same yield and maturity

                    guidelines for evaluating the effect of interest rate
                    changes on the Fund and determining the degree of interest

                    yields or expected changes in the share price of the Fund.

Credit risk is
expected to be
low                 Credit risk depends on the average quality of the Fund's
                    underlying securities and the Fund's degree of
                    diversification. The Fund 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
                    the Fund 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 Florida municipal obligations.

                    To minimize the effects of concentrating its investments in
                    Florida obligations, 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 use of municipal bond
                    insurance should minimize the credit risk associated with
                    the Fund.

WHO SHOULD 
INVEST              The Fund is intended for Florida residents seeking income  
                    that is exempt from federal personal income taxes. The Fund
Florida residents   also provides an investment which is expected to be exempt 
seeking a           from the Florida intangible personal property tax. As a    
tax-exempt          rule, tax-free income is attractive to investors in high   
investment          federal tax brackets. You can determine whether tax-exempt 
                    or taxable income is more attractive in your own case by   
                    comparing the Fund's tax-free yield with the yield from a  
                    comparable taxable mutual fund investment. See "How to     
                    Compare Tax-Free and Taxable Yields".                      
                    


                                                                               7
<PAGE>

                    Assuming that tax-free income is attractive in your own tax
                    bracket, you should weigh an investment in the Fund in terms
                    of its expected yield and price volatility, and your own
                    investment objectives, risk preferences, and time horizon.
                    The Fund is suitable 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 Fund is expected
                    to be higher, and the level of income provided more stable,
                    than that provided by other mutual funds which invest in
                    short-term securities. However, because of the Fund's
                    potential price volatility, the Fund 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 movements. 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  
                    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 calculate   
                    the "taxable equivalent yield" for the Fund you are         
                    considering, and compare it with the yield of a taxable     
                    investment with similar credit and maturity characteristics.
                                                                                
                    The taxable equivalent yield for a Fund is based upon the   
                    Fund's current tax- exempt yield and your federal tax       
                    bracket. The formula is:                                    
                                                                                
                          Fund's Tax-Free Yield             Your Taxable        
                          ---------------------        =  Equivalent Yield      
                     100% - Your Federal Tax Bracket                            
                                                                                
                    For example, if you are in a federal tax bracket of 28%, and
                    the Fund's tax-free yield is 6%, the Fund's taxable         
                    equivalent yield would be 8.33%:                            
                                                                                
                                      6%                                        
                                    ------      =   8.33%                       
                                  100% - 28%                                    
                                                                                
                    In this example, you would choose the tax-free investment if
                    the 8.33% 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.                          
The Fund invests                                                                
in municipal        The Fund invests principally in tax-exempt Florida municipal
bonds, notes and    securities, which are debt obligations issued by Florida    
securities          state and local governments and public financing authorities
derived from        (and by certain U.S. territories) that provide interest     
municipal bonds     income that is exempt from federal income taxes. Such       
and notes           securities are also exempt from the Florida intangible      
                    personal property tax. Municipal securities include both    
                    municipal bonds (those securities 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 various 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, and 
                    demand notes. 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        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.
                                                                               9

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 by the Fund    To provide an added level of credit protection, the Fund
                    purchases securities which have one of the following 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 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 Fund, the annual premiums for the policy
                    are likely to range from 0.10% to 0.40% of the principal
                    value of the bonds insured under the policy, thereby
                    reducing the Fund's current yield.

                    A secondary market insurance policy is purchased by an
                    investor (such as the Fund) subsequent to the bond's
                    original issuance and generally insures a particular bond
                    for the remainder of its term. The Fund may purchase bonds
                    that have already been insured under a secondary market
                    insurance policy by a prior investor, or the Fund may itself
                    purchase such a policy from Financial Guaranty for bonds
                    that are currently uninsured.

                    An insured municipal bond in the Fund 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 Fund's mutual fund insurance
                    policy. All of the insurance policies used by the Fund will
                    be obtained only from companies whose insurance
                    claims-paying ability is 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 Fund may
report an
effective
average weighted
maturity            The Fund observes strict maturity guidelines as set forth in
                    detail under "Investment Policies." These maturity standards
                    are specified in terms of the Fund's average weighted
                    maturity. From time to time, however, the Fund may also

                    report an effective average weighted maturity, which
                    reflects, among other items, the likelihood that a municipal
                    bond or note held by the Fund may be redeemed or "called"
                    prior to its stated maturity date. For example, if the Fund
                    consists entirely of 20-year bonds, some of which may be
                    "called" prior to their stated maturity in 20 years, the
                    Fund's average weighted maturity will be 20 years, while its
                    effective average maturity will be shorter.

                    The Fund'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 Fund's
                    underlying investment securities. For example, if interest
                    rates decline, a greater proportion of the Fund'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 Fund will shorten,
                    independent of actual purchases or sales of portfolio
                    securities.

   
Temporary
Investments         Except as described on page 4, the Fund will not invest in
                    securities other than municipal bonds except that the Fund
                    may make investments for temporary 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, 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 Investment Company
                    Act of 1940; and (c) any such securities or municipal bonds
                    subject to repurchase agreements.
    
The Fund may
purchase
when-issued
securities          The Fund may invest up to 20% of its assets under normal
                    circumstances in tax-exempt securities that are purchased on
                    a "when-issued" basis. In buying "when-issued" securities,
                    the Fund commits to buy securities at a certain price even
                    though the securities may not be delivered for a certain
                    period. The Fund 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      The Fund may lend its investment securities for either
                    short-term or long-term purposes to qualified institutional
                    investors for the purpose of realizing additional net
                    investment income. Loans of securities by a Fund 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, the Fund will limit such activity in accordance
                    with its investment objective.

The Fund may invest
in municipal lease
obligations         The Fund 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 therefore cause a loss to investors.

                                                                              11

Portfolio turnover
is not expected to
exceed 150%         Although it generally seeks to invest for the long term, the
                    Fund retains the right to sell securities irrespective of
                    how long they have been held. It is anticipated that the
                    annual portfolio turnover of the Fund will not exceed 150%.
                    A turnover rate of 150% would occur, for example, if all of
                    the securities of the Fund were replaced within eight
                    months.


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 Fund may 
invest in
derivative
securities          The Fund may invest in conventional derivative securities
                    including futures contracts and options, but only to a
                    limited extent. The Fund may enter into futures contracts
                    provided that not more than 5% of its assets are required as
                    a futures contract deposit; in addition, the Fund 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 Fund'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 Fund may invest a portion of its assets in
                    a bond futures contract. Because futures contracts only
                    require a small initial margin deposit, the Fund would then
                    be able to maintain a 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 Fund's total transaction costs.
   
                    The Fund 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 Fund's bond holdings.
    
                    The Fund may invest in partnerships and grantor trust
                    derivative products. However, prior to the purchase of such
                    security, a determination must be made by the Fund 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 the Fund 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

12
<PAGE>


                    correlation will be minimized by investing in those
                    contracts whose price fluctuations are expected to resemble
                    those of the Fund's underlying securities. The risk that the
                    Fund 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 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 Fund 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 Fund will attempt to minimize
                    the risks of partnership and grantor trust derivative
                    products by carefully selecting which securities to purchase
                    and constantly monitoring securities held by the Fund.

INVESTMENT
LIMITATIONS         The Fund has adopted certain limitations designed to reduce 
                    its exposure to specific situations. These limitations      
The Fund has        include the following:                                      
adopted certain                                                                 
fundamental         a) The Fund will invest a minimum of 80% of its net assets  
limitations            in insured Florida municipal bonds. The interest on such 
                       bonds is exempt from federal personal income, and such   
                       bonds are also exempt from the Florida intangible        
                       personal property tax, except that the Fund may make     
                       temporary investments as described above.                
                                                                                
                    b) At the close of each quarter of the taxable year, the    
                       Fund will limit the aggregate value of all holdings,     
                       except U.S. Government and cash items, as defined in the 
                       Internal Revenue Code (the "Code"), each of which exceeds
                       5% of the Fund's total assets, to an aggregate amount of 
                       50% of such assets.                                      
                                                                                
                    c) The Fund 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 Fund'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.                                           
                                                                                
                    d) The Fund will not borrow money except for temporary or   
                       emergency purposes, and then not in excess of 10% of the 
                       Fund's total assets. The Fund will repay all borrowings  
                       before making additional investments, and the interest   
                       paid on such borrowings will reduce income.              
                                                                                
                    e) The Fund will not pledge, mortgage, or hypothecate more  
                       than 10% of its total assets.                            
                                                                                
                    

                    
                    

                                                                              13

                    These investment limitations are considered at the time
                    investment securities are purchased. The limitations
                    described here and in the Statement of Additional
                    Information may be changed only with the approval of a
                    majority of the Fund's shareholders.


MANAGEMENT OF
THE FUND            The Fund is a member of The Vanguard Group of Investment  
                    Companies, a family of more than 30 investment companies    
Vanguard            with more than 90 distinct investment portfolios and total  
administers         assets in excess of $190 billion. Through their             
and distributes     jointly-owned subsidiary, The Vanguard Group, Inc.          
the Fund            ("Vanguard"), the Fund and the other funds in the Group     
                    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

                    However, each fund bears its share of the Group's           
                    distribution costs.

INVESTMENT
ADVISER             The Fund receives all investment advisory services on an    
                    at-cost basis from Vanguard's Fixed Income Group. The Group 
Vanguard manages    also provides investment advisory services to more than 40  
the Fund's          Vanguard money market and bond portfolios, both taxable and 
investments         tax-exempt. Total assets under 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.

                    o Reid Smith, a Principal of Vanguard, serves as portfolio
                      manager of the Florida Insured Tax-Free Fund. Mr. Smith
                      has managed the Fund since its inception in 1992. 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 and continuously
                    reviews, supervises and administers the Fund'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 is based on: (a) continuing
                    credit analysis of those instruments held in the Fund and
                    those being considered for inclusion therein; (b) possible
                    disparities in yield relationships between different
                    fixed-income securities; 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 Fixed
                    Income Group may sell portfolio securities prior to their
                    maturity if circumstances and considerations warrant and if
                    it believes such dispositions advisable. The Fixed Income
                    Group 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 the Fund are declared daily and are payable to           
The Fund pays       shareholders of record at the close of the previous business
month-end           day. Such dividends are paid on the first business day of   
dividends           each month. Net capital gains distributions, if any, will be
                    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           
                    distributions methods.                                      
                                                                        
                    In addition, in order to satisfy certain distribution       
                    requirements of the Tax Reform Act of 1986, the Fund 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 Fund and received by shareholders by       
                    December 31 of the prior year.                              

Dividends will be
exempt from federal
income taxes        The Fund intends to continue to qualify for taxation as a
                    "regulated investment company" under the Internal Revenue
                    Code so that it will not be subject to federal income tax to
                    the extent its income is distributed to shareholders. In
                    addition, the Fund 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 gross income for federal income 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.

                                                                              15

Fund shares will
be exempt from
the Florida
intangible tax      Although Florida does not have a state personal income tax,
                    it does impose an intangible personal property tax on
                    certain financial assets, including shares of mutual funds.
                    Unlike other state and local taxes, which are assessed on
                    ordinary income and capital gains derived from mutual fund
                    shares, the Florida intangible personal property tax is
                    based on the net asset value of shares owned as of December
                    31.

                    Under Florida law, shares of a mutual fund will be exempt
                    from the intangible personal property tax to the extent
                    that, on the annual assessment date (January 1), its assets
                    are solely invested in certain exempt Florida securities,
                    U.S. Government securities, certain short-term cash
                    investments, or other exempt securities. If, on the annual
                    assessment date (January 1), the Fund's assets are invested
                    in both tax-exempt and non-tax-exempt securities, only that
                    portion of a share's net asset value represented by U.S.
                    Government securities (including qualifying obligations of
                    U.S. territories and possessions) will be exempt from the
                    intangibles tax. Because the Fund is expected to invest only
                    in exempt Florida municipal obligations (and certain
                    short-term cash investments), shares of the Fund will be
                    exempt from the Florida intangible personal property tax for
                    Florida residents.

                    However, under certain circumstances, the Fund may invest in
                    securities other than Florida municipal obligations. In such
                    cases, all or a portion of the value of the Fund's shares
                    may be subject to the Florida intangible personal property
                    tax, and a portion of the Fund's income may be subject to
                    federal income taxes.


                    Net long-term capital gains realized by the Fund 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 tax purposes. In general, such taxable income
                    distributions from the Fund are expected to be negligible in
                    comparison with tax-exempt dividends.

                    At present, the Fund does not invest in AMT bonds. (See
                    "Investment Policies.") However, were the Fund to invest in
                    such bonds, all or a portion of the Fund'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 the Fund's shares 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 Fund 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 the Fund 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
                    income from the Fund, is used to calculate the taxable
                    portion of Social Security benefits.

                    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 THE FUND         The share price or "net asset value" per share of the Fund
                    is determined daily by dividing the total value of the
                    investments and other assets of the Fund, less any
                    liabilities, by the total outstanding shares of the Fund.
                    The net asset value per share of the Fund 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.

                    When approved by the Board of Trustees, bonds and other
                    fixed-income securities of the Fund may be valued on the
                    basis of 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 the Trustees.
                    There are a number of pricing services available and the
                    Trustees, on the basis of ongoing 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 Fund can be found daily in the
                    mutual fund section of most major newspapers under the
                    heading of Vanguard.

GENERAL
INFORMATION         Vanguard Florida Insured 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
                    one class of shares.


                    Shares of the Fund when issued are fully paid and
                    non-assessable; participate equally in dividends,
                    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
                    more than 50% of the shares voting for the election of the
                    Trustees can elect all of the Trustees if they so choose.

                    Annual meetings of shareholders will not be held except as
                    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.,
                    Philadelphia, PA. The Vanguard Group, Inc., Valley Forge,
                    PA, serves as the Fund's Transfer and Dividend Disbursing
                    Agent. Price Waterhouse LLP serves as independent
                    accountants for the Fund and audits its financial statements
                    annually. The Fund is not involved in any litigation.

                    The Fund'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.
 
Additional

                    wire ($1,000), exchange from another Vanguard Fund account
                    ($100 minimum), or Vanguard Fund Express.

OPTION              You must select one of three distribution options:

                    1. Automatic Reinvestment Option--Both dividends and capital
                       gains distributions will be reinvested in additional Fund
                       shares. This option will be selected for you
                       automatically unless you specify one of the other
                       options.

                    2. Cash Dividend Option--Your dividends will be paid in cash
                       and your capital gains will be reinvested in additional
                       Fund shares.

                    3. All Cash Option--Both dividend and capital gains
                       distributions will be paid in cash.

                    You may change your option by calling our Client Services
                    Department (1-800- 662-2739).

                    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             
Investors should    shareholders. These distributions are made to all           
ask about the       shareholders who own Fund shares as of the distribution's   
timing of           record date, regardless of how long the shares have been    
capital gains       owned. Purchasing shares just prior to the record date could
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 distribution,  
                    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."

Optional Services  your account is to select the options you desire when you    
                   complete your Account Registration Form. If you wish to add  
                   shareholder options later, you may need to provide Vanguard

                   for further assistance.                                      
                    

Signature
Guarantees          For our mutual protection, we may require a signature
                    guarantee on certain written transaction requests. A
                    signature guarantee verifies the authenticity of your
                    signature, and may be obtained from banks, brokers and any
                    other guarantor that Vanguard deems acceptable. A signature
                    guarantee cannot be provided by a notary public.

Certificates        Share certificates will not be issued for the Fund.

                    registered broker-dealer or investment adviser, the
                    broker-dealer or adviser may charge a service fee.

Cancelling Trades   The Fund will not cancel any trade (e.g., a purchase,
                    exchange or redemption) believed to be authentic, received
                    in writing or by telephone, once the trade request has been 
                    received. 

                                                                              21

- -------------------------------------------------------------------------------
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 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 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.)

                    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.
- -------------------------------------------------------------------------------
SELLING YOUR
SHARES              You may withdraw any portion of the funds in your account by
                    redeeming shares at any time. You generally may initiate a
                    request by writing or by telephoning. Your redemption
                    proceeds are normally mailed, credited or wired--depending
                    upon the method of withdrawal you have previously
                    chosen--within two business days after the receipt of the
                    request in Good Order.


Selling By Writing
a Check             You may withdraw funds from your account by writing a check
                    payable in the amount of $250 or more. When a check is
                    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
                    business days. There is no charge for checks or for their

22
<PAGE>

                    clearance. Corporations, trusts and other organizations
                    should call or write our Client Services Department
                    (1-800-662-2739) before submitting signature cards, as
                    additional documents may be required to establish the
                    checkwriting service.

                    Before establishing the checkwriting option, you should be
                    aware that:

                    1. Writing a check (a redemption of shares) is a taxable
                       event.
                    2. The Fund does not allow an account to be closed through
                       the checkwriting option.

                       in writing.
                    4. The Fund reserves the right to terminate or alter this
                       service at any time.

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 either by mail or by wire. In addition
                    to the details below, 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.


                                                                              23

                    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, 
                    money will be automatically moved from your Vanguard Fund   
Automatic           account to your bank account according to the schedule you  
Withdrawal &        have selected. The Special Redemption option lets you move  
Special             money from your Vanguard account to your bank account on an

                    please provide the appropriate information on the Account

Selling By
Exchange            You may sell shares of the Fund by making an exchange to
                    another Vanguard Fund account. Please see "Exchanging Your
                    Shares" for details.
                    -----------------------------------------------------------
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
                    above 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

<PAGE>

                    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). The 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 requirement. 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 Fund's net asset value).

                    close of business that same day. Requests received after the
                    close of the Exchange are processed the next business day.

                    Balanced Index, Vanguard Index Trust, Vanguard International

                    -----------------------------------------------------------
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 the 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 documents 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 exchange privilege is only available in Florida, 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 the Fund during any twelve-month period.
                    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.
                    Additionally, the Fund has limited exchange privileges at
                    calendar year-end in the past for tax reasons, and is
                    expected to do so in the future.

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 Fund; (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.

                    to another person by completing a transfer form and sending

                            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 the Fund. 

   1. The Fund will not invest in securities other than municipal bonds, 
except that it may make temporary investments in (a) notes issued by or on 
behalf of municipal or corporate issuers, obligations of the United States 
Government and its agencies or instrumentalities, commercial paper, and bank 
certificates of deposit, (b) any investment companies investing in such 
securities which have investment objectives and policies consistent with 
those of the Fund to the extent permitted by the 1940 Act; and (c) any such 
securities or Municipal Bonds subject to short-term repurchase agreements; 

   2. The Fund 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; 

   3. The Fund 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 Fund'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; 

   4. The Fund 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 Fund. The Fund will repay all borrowing before making 
additional investments. Interest paid on such borrowings will reduce income; 

   5. The Fund will not pledge, mortgage or hypothecate its assets to any 
extent greater than 10% of the value of the total assets of the Fund; 

                                                                             B-1
<PAGE>
   6. The Fund will not issue senior securities as defined in the 1940 Act; 

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

   8. The Fund will not purchase or sell real estate, but this shall not 
prevent investments in Municipal Bonds secured by real estate or interests 
therein; 

   9. The Fund 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. The Fund will not purchase on margin or sell short, except as 
specified below in Investment Limitation No. 12; 

   11. The Fund 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. The Fund will not purchase or sell commodities or commodities 
contracts, except that the Fund may invest in bond futures contracts, bond 
options and options on bond futures contracts to the extent that not more 
than 5% of the Fund's assets are required as deposit on futures contracts; 

   13. The Fund will not invest its assets in securities of other investment 
companies except as they may be acquired as part of a merger, consolidation, 
reorganization or purchase of assets approved by the Portfolio's shareholders 
or otherwise to the extent permitted by Section 12 of the 1940 Act; 

   14. The Fund 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; 

   15. The Fund 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; and 

   16. The Fund will not purchase or otherwise acquire any security 
(including the Fund's investment in The Vanguard Group, Inc.) if, as a 
result, more than 15% of its net assets would be invested in securities that 
are illiquid. 

   The above-mentioned investment limitations are considered at the time 
investment securities are purchased. Notwithstanding these limitations, the 
Fund 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, under normal circumstances 
the Fund may invest up to 20% of its assets in when-issued securities. Please 
see the prospectus for a description of such securities. 


                             INVESTMENT POLICIES 

   Repurchase Agreements The Fund may invest in repurchase agreements with 
commercial banks, brokers or dealers either for defensive purposes due to 
market conditions or to generate income from its excess cash balances. A 
repurchase agreement is an agreement under which the Fund acquires a money 
market instrument (generally a security issued by the U.S. Government or an 

B-2
<PAGE>


agency thereof, a banker's acceptance or a certificate of deposit) from a
commercial bank, broker or dealer, subject to resale to the seller at an agreed
upon price and date (normally, the next business day). A repurchase agreement
may be considered a loan collateralized by securities. The resale price reflects
an agreed upon interest rate effective for the period the instrument is held by
the Fund and is unrelated to the interest rate on the underlying instrument. In
these transactions, the securities acquired by the Fund (including accrued
interest earned thereon) must have a total value in excess of the value of the
repurchase agreement and are held by the Fund's custodian bank until
repurchased. In addition, the Fund's Board of Trustees will monitor the Fund's
repurchase agreement transactions generally and will establish guidelines and
standards for review by the investment adviser of the creditworthiness of any
bank, broker or dealer party to a repurchase agreement with the Fund. No more
than an aggregate of 15% of a Fund's assets, at the time of investment, will be
invested in repurchase agreements having maturities longer than seven days and
securities subject to legal or contractual restrictions on resale, for which
there are no readily available market quotations.

   The use of repurchase agreements involves certain risks. For example, if 
the other party to the agreement defaults on its obligations to repurchase 
the underlying security at a time when the value of the security has 
declined, the Fund may incur a loss upon disposition of the security. If the 
other party to an agreement becomes insolvent and subject to liquidation or 
reorganization under the Bankruptcy Code or other laws, a court may determine 
that the underlying security is collateral for a loan by the Fund not within 
the control of the Fund and therefore the realization by the Fund on such 
collateral may be automatically stayed. Finally, it is possible that the Fund 
may not be able to substantiate its interest in the underlying security and 
may be deemed an unsecured creditor of the other party to the agreement. 
While the Fund's management acknowledges these risks, it is expected that 
they can be controlled through careful monitoring procedures. 

   Lending of Securities  The Fund 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 Fund attempts to increase its income through the 
receipt of interest on the loan. Any gain 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 Fund. The Fund 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 
Investment Company Act of 1940, 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 Fund 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 Fund at any time and (d) the Fund receive reasonable interest on the 
loan (which may include the Fund investing any cash collateral in interest 
bearing short-term investments), any distribution on the loaned securities 
and any increase in their market value. The Fund 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 Fund 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 Fund 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. 

                                                                             B-3
<PAGE>

   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 rates of underlying securities. The Fund intends to use 
futures contracts only for bona fide hedging purposes. 

   Regulations of the CFTC applicable to the Fund require that all of its 
futures transactions constitute bona fide hedging transactions. The Fund 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 
Fund 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 Fund upon sale of open futures 
contracts. 

   Although techniques other than the sale and purchase of futures contracts 
could be used to control the Fund's exposure to market fluctuations, the use 
of futures contracts may be a more effective means of hedging this exposure. 
While the Fund 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 Fund 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 Fund will not enter into 
futures contracts to the extent that its outstanding obligations to purchase 
securities under these contracts would exceed 20% of the Fund's total assets. 


   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 Fund would continue to be required to make daily cash 
payments to maintain its required margin. In such situations, if the Fund 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 Fund 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 Fund. 


B-4
<PAGE>

   The Fund 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 principal interest rate futures exchanges in the United States 
are the Board of Trade of the City of Chicago and the Chicago Mercantile 
Exchange. 

   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 Fund are engaged in only for hedging 
purposes, the Adviser does not believe that the Fund is subject to the risks 
of loss frequently associated with futures transactions. The Fund 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 Fund does involve the risk of 
imperfect or no correlation where the securities underlying futures contracts 
have different maturities or other characteristics than the portfolio 
securities being hedged. It is also possible that the Fund 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 Fund of margin 
deposits in the event of bankruptcy of a broker with whom the Fund has an 
open position in a futures contract or related option. 

   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 Fund is required for 
federal income tax purposes to recognize as income for each taxable year its 
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 Fund may affect the holding 
period of such securities and, consequently, the nature of the gain or loss 
on such securities upon disposition. The Fund may be required to defer the 
recognition of losses on futures contracts to the extent of any unrecognized 
gains or related positions held by the Fund. 

   In order for the Fund 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 Fund'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 Fund'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 Fund 

                                                                             B-5
<PAGE>

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 Fund'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.

   The Fund 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 Fund's fiscal year) on futures 
transactions. Such distributions will be combined with distributions of 
capital gains realized on the Fund's other investments and shareholders will 
be advised on the nature of the transactions. 


                                 RISK FACTORS 
                    VANGUARD FLORIDA INSURED TAX-FREE FUND 

   Vanguard Florida Insured Tax-Free Fund invests primarily in the debt 
obligations of Florida State government, the State's agencies and 
authorities, and various local governments, including counties, cities, 
towns, 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 credit rating among American states for full "faith and 
credit" state debt is Aa as determined by Moody's Investors Service and AA as 
determined by Standard & Poor's Corporation. Against this measure and the 
criteria listed above, the credit risk associated with direct obligations of 
the State of Florida and the State's agencies and authorities, including 
general obligation and revenue bonds, lease debt, and notes, is comparable 
with the average for U.S. states. Florida's general obligation bonds have 
been rated Aa/AA by both rating agencies for over two decades, during which 
period the State's obligations could be characterized as providing high-grade 
security with a very strong capacity for timely repayment of debt. 


   The State of Florida's economy is characterized by a large service sector, 
a dependence on the tourism and construction industries, and a large 
retirement population. The management of rapid growth has been the major 
challenge facing state and local governments. While attracting many senior 
citizens, Florida also offers a favorable business environment and growing 
employment opportunities that have continued to generate working-age 
population in-migration. As this growth continues, particularly within the 
retirement population, the demand for both public and private services will 
increase, which may strain the service sector's capacity and impede the 
State's budget balancing efforts. 


   During the 1980s, Florida outperformed the nation as measured by such 
economic indicators as employment growth and income levels. Florida's job 
creation rate in the non-agriculture sector was the highest of the eleven 
most populous states. Fueling this growth in jobs were the continued boom in 
the tourism industry and related service sectors and a dynamic construction 
and construction-related manufacturing sector. Florida's economy did not 
suffer the dislocation and restructuring of the more manufacturing-based 
economies of the Midwest and the North during the 1980s and was less exposed 
to the decline of the textile industry besieging much of the Southeast. 

   The primary vulnerability in the Florida economy is exposure to the 
business cycle affecting both the tourism and construction industries. 
Gasoline prices and supply can also impact tourism. An economic recession 
reached Florida in 1991 and impacted the service sector considerably, causing 
the State to experience an actual job loss for the first time in decades. 
While Florida's aerospace and defense contracting industries are now in 
decline, the State's manufacturing economy has diversified into high-tech and 
electronic equipment and has been strengthened by a growth in exports. 
Furthermore, construction jobs as a percent of total jobs in the State have 
declined during the late '80s, reducing cyclical risk. The outlook for the 
Florida economy is continued expansion fueled by population growth--but at a 
slower rate than that of the 1980s.

<PAGE>

   Personal income levels in Florida are greater than the U.S. average and 
continue to grow at a faster rate. These levels in Florida are also less 
sensitive to economic downturns than in the U.S., as a whole, since Florida 
is home to a greater concentration of senior citizens who rely on dividends, 
interest, Social Security, and pension benefits, which fluctuate less with 
the business cycle than does employment income. 

   Debt levels in the State of Florida are moderate to high, reflecting the 
tremendous capital demands associated with rapid population growth. Florida 
is unusual among states in that all general obligation "full faith and 
credit" debt issues of municipalities must be approved by public referendum 
and are, therefore, relatively rare. Most debt instruments issued by local 
municipalities and authorities have a more narrow pledge of security, such as 
a sales tax stream, special assessment revenue, user fees, utility taxes, or 
fuel taxes. Credit quality of such debt instruments tends to be somewhat 
lower than that of general obligation debt. The State of Florida issues 
general obligation debt for a variety of purposes; however, the State 
constitution requires a specific revenue stream to be pledged to State 
general obligation bonds as well. 

   The market for Florida bonds secured by municipal leases has suffered due 
to the default of the State of Florida on a private placement lease financing 
of an office building in 1989 and several episodes of public consideration 
(although never carried out) by Brevard County to not appropriate funds to 
meet its obligation under a tax-exempt lease financing. 


   The State of Florida generated steadily increasing fund balances during 
the 1980s as the State experienced record growth. However, the State 
experienced budget strain during the early 1990s due to an economic 
recession. The State's dependence on the sales tax as a primary source of 
revenue compounded the recession's impact. State officials acted quickly and 
responsibly to maintain a balanced budget by revising revenue projections and 
controlling spending. Such responsible fiscal management enhances overall 
credit quality in the State of Florida. 


   The state's economic and financial condition is showing signs of strength 
as the state and national economies emerge from recession in the mid-1990's. 
State officials, however, still face tremendous capital and operating 
pressures due to the growth that will continue to strain the State's narrow 
revenue base. Future budgets may require a wider revenue base to meet such 
demands; the most likely candidate for such revenue enhancement is a tax on 
consumer services. The creation of a Florida personal income tax is a very 
remote possibility, since it would require an amendment to the State's 
Constitution and a higher level of political support than has currently been 
generated. 


                   FLORIDA INTANGIBLE PERSONAL PROPERTY TAX 

   Although Florida does not have a state personal income tax, it does impose 
an intangible personal property tax on certain financial assets, including 
mutual fund shares. The most common examples of personal property subject to 
the tax are shares of stock issued by corporations, bonds issued by 
corporations or state, county or municipal governments outside the State of 
Florida, and shares of ownership in mutual funds. Unlike most state and local 
taxes which are assessed on ordinary income and capital gains derived from 
mutual fund shares, the Florida intangible tax is based on the net asset 
value of these shares. Under Florida law, shares of a mutual fund will be 
exempt from the intangibles tax to the extent that, on the annual assessment 
date (December 31), its assets are solely invested in exempt Florida 
securities, exempt U.S. Government securities, or other exempt securities. 
If, on the annual assessment date, the Fund's assets are invested in both 
exempt and non-exempt securities, only that portion of a share's net asset 
value represented by U.S. Government securities (including qualifying 
obligations of U.S. territories and possessions) will be exempt from the 
intangibles tax. Under this rule, shares of the Vanguard Florida Insured 
Tax-Free Fund are expected to be exempt from the Florida intangible personal 
property tax. 



                            YIELD AND TOTAL RETURN 


   The yield of the Fund for the 30-day period ended November 30, 1995 was 
5.08%. The total return of the Fund for the year ended November 30, 1995 was 
+20.05%. The average annual total return for the Fund since inception on 
September 1, 1992 was +8.50%. 
                                                                            B-7

                            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. 

                                                                             B-9
<PAGE>

   A change in securities held by the Fund is known as "portfolio turnover" 
and may involve the payment of 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 the Fund is set forth under the heading "Financial 
Highlights" in the Fund's 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. 



                              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. 

   Your purchase will be made in full and fractional shares of the Fund 
calculated to three decimal places. Shares are held on deposit for 
shareholders by the Fund, which will send to shareholders a statement of 
shares owned at the time of each transaction. Share certificates will not be 
issued for the Fund. 


                             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 $5000 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 a bank broker or any other 
guarantor that Vanguard deems to be acceptable. 

   The signature guarantees must appear either: (1) on the written request 
for redemption or (2) on a separate instrument for assignment ("stock power") 
which should specify the total number of shares to be redeemed.

THE VANGUARD GROUP 

   The 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 other Vanguard Funds, including the Vanguard Florida Insured 
Tax-Free Fund. 

                                                                            B-11
<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. 

   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 was established and operates under a Funds' Service 
Agreement which was approved by the shareholders of each of the Funds. The 
amounts which each of the Funds have 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, the Fund had contributed $48,000 representing .2 of 1% of 
Vanguard's Capitalization. The Funds' Service Agreement provides for the 
following arrangement: (1) each Vanguard Fund may invest a maximum of 0.40% 
of its assets in Vanguard and (2) there is no restriction on the maximum cash 
investment that the Vanguard Funds may make in Vanguard. 

   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 year ended November 30, 1995, the Fund's share of Vanguard's actual net 
costs of operations relating to management and administrative services 
(including transfer agency) totaled approximately $568,000. 

   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 $84,000 of the Group's 
distribution and marketing expenses, which represented an effective annual 
rate of .02 of 1% of the Fund's average net assets. 


   Investment Advisory Services.  Vanguard also provides investment advisory 
services to the Fund, Vanguard Municipal Bond Fund, Vanguard Money Market 
Reserves, Vanguard California Tax- Free Fund, Vanguard Pennsylvania Tax-Free

   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 $1,000 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 $12,199. 

   Upon retirement, Trustees who are not Officers are paid an annual fee 
based upon the number of years of service on the Board. The fee is equal to 
$1,000 for each year of service up to a maximum of $15,000. Under its 
retirement plan, Vanguard contributes annually an amount equal to 10% of each 
officer's annual compensation plus 5.7% of that part of the officer's 
compensation during the year, if any, that exceed the Social Security Taxable 
Wage Base then in effect. Under Vanguard's thrift plan, all employees are 
permitted to make pre-tax contributions in a maximum amount equal to 4% of 
total compensation. Vanguard matches the basic contribution on a 100% basis. 
During the year ended November 30, 1995, the Fund's proportionate share of 
retirement benefits paid to all officers of the Fund as a group, was 
approximately $300.

                   DESCRIPTION OF SHARES AND VOTING RIGHTS 

   The Fund was organized as a Pennsylvania Trust on May 22, 1992. 

   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 one Portfolio. 

   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 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 proceeds or 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 circumstances 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 

                                                                            B-15
<PAGE>

Municipal Bonds. Similar proposals may be introduced in the future. If any such
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 5.) 

   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 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 or 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.

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 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.
