YIELD AND        From time to time a Portfolio of the Fund may advertise its
TOTAL RETURN     yield and total return. Both yield and total return figures
                 are based on historical earnings and are not intended to in-
                 dicate future performance. The "total return" of a Portfolio
                 refers to the average annual compounded rates of return over
                 one-, five- and ten-year periods or over the life of a Port-
                 folio (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 distribu-
                 tions.
 
                 In accordance with industry guidelines set forth by the U.S.
                 Securities and Exchange Commission, the "30-day yield" of the
                 Insured Long-Term Portfolio is calculated by dividing the net
                 investment income per share earned during a 30-day period by
                 the net asset value per share on the last day of the period.
                 Net investment income includes interest and dividend income
                 earned on the Portfolio's securities; it is net of all ex-
                 penses and all recurring and nonrecurring charges that have
                 been applied to all shareholder accounts. The yield calcula-
                 tion assumes that the net investment income earned over 30
                 days is compounded monthly for six months and then
                 annualized.

                 The "seven-day" or "current" yield of the Money Market Port-
                 folio reflects the income earned by a hypothetical account in
                 the Portfolio during a seven-day period, expressed as an an-
                 nual percentage rate. The "effective yield" of the Money Mar-
                 ket Portfolio assumes the income over the seven-day period is
                 reinvested weekly, resulting in a slightly higher stated
                 yield through compounding.
 
                 Methods used to calculate advertised yields are standardized
                 for all money market and bond funds. However, these methods
                 differ from the accounting methods used by the Portfolios to
                 maintain their books and records, and so advertised yields
                 may not fully reflect the income paid to your own account or
                 the yield reported in the Portfolio's Annual Report to Share-
                 holders.

INVESTMENT       The Fund consists of the New Jersey Money Market Portfolio
OBJECTIVE        and the New Jersey Insured Long-Term Portfolio, each of which
                 has a distinct investment objective:
 
   
THE FUND SEEKS   . The objective of the NEW JERSEY MONEY MARKET PORTFOLIO is
TO PROVIDE         to provide investors with income that is exempt from both
INCOME THAT IS     federal and New Jersey personal income taxes. The Portfolio
EXEMPT FROM        also seeks to maintain, but does not guarantee, a constant
FEDERAL AND        net asset value of $1.00 per share. The Portfolio invests
NEW JERSEY         in high-quality instruments, and an investment in the
INCOME TAXES       Portfolio is neither insured nor guaranteed by the U.S.
                   Government.     
 
                 . The objective of the NEW JERSEY INSURED LONG-TERM PORTFOLIO
                   is to provide investors with a high level of income that is
                   exempt from federal and New Jersey personal income taxes.
 
                 The two Portfolios of the Fund are available only to invest-
                 ors who reside in New Jersey. There is no assurance that ei-
                 ther Portfolio of the Fund will achieve its stated objective.
 
                 The investment objective of each Portfolio is fundamental and
                 so may not be changed without the approval of a majority of
                 the Fund's shareholders.
--------------------------------------------------------------------------------
INVESTMENT       Each Portfolio of the Fund will invest at least 80% of its
POLICIES         net assets in New Jersey municipal securities, exclusive of
                 New Jersey AMT bonds (see page 6). New Jersey municipal secu-
                 rities are debt obligations issued by New Jersey state and
                 local governments and public financing authorities (and by
                 certain U.S. territories) that provide interest income that
                 is exempt from both federal and New Jersey personal income
                 taxes. The New Jersey municipal securities described above,
                 may include securities in which the tax exempt interest rate
                 is determined by an index, swap or some other formula. Al-
                 though both invest primarily in New Jersey municipal obliga-
                 tions, the two Portfolios differ in terms of credit quality
                 and maturity standards.
 
 
                                                                               5

THE MONEY        Under normal circumstances, the New Jersey Money Market Port-
MARKET           folio will invest at least 80% of its net assets (and 80% of
PORTFOLIO WILL   the aggregate principal amount of all of its investments) in
INVEST IN        the following high quality, short-term New Jersey municipal
SHORT-TERM NEW   securities:
JERSEY          
MUNICIPAL        . Municipal notes and variable rate demand instruments, in-
SECURITIES         cluding 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 ("Stan-
                   dard & Poor's");
 
                 . Tax-exempt commercial paper rated P-1 by Moody's or A-1+ or
                   A-1 by Standard & Poor's;
 
                 . Municipal, including derivative securities, bonds with an
                   effective maturity of 13 months or less rated a minimum of
                   A by Moody's or Standard & Poor's; and
 
                 . Unrated municipal notes considered by the Board of Trustees
                   to be comparable in credit quality to securities rated MIG-
                   1 by Moody's or SP-1+ or SP-1 by Standard & Poor's.
 
                 In seeking to provide a stable share price of $1.00, the New
                 Jersey Money Market Portfolio is expected to maintain an av-
                 erage weighted maturity of 90 days or less, and will purchase
                 securities with an effective maturity of 13 months or less
                 which are eligible for purchase under Rule 2a-7 of the In-
                 vestment Company Act of 1940 (the "1940 Act").
 
                 Normally, the New Jersey Money Market Portfolio will seek to
                 invest substantially all of its assets in the short-term New
                 Jersey municipal obligations listed above. However, under
                 certain circumstances, such as a temporary decline in the is-
                 suance of New Jersey obligations, the Portfolio may invest up
                 to 20% of its assets in the following: short-term municipal
                 securities issued outside of New Jersey (the income from
                 which may be subject to New Jersey income taxes) or certain
                 taxable fixed-income securities (the income from which may be
                 subject to federal and New Jersey income taxes).
 
                 Subject to the same 20% limit, the Portfolio is also autho-
                 rized to invest in short-term New Jersey AMT bonds. The in-
                 come from New Jersey AMT bonds is exempt from regular federal
                 and New Jersey income taxes, but may be a tax preference item
                 for purposes of the federal alternative minimum tax, see "Im-
                 plementation of Policies."
 
                 Under unusual circumstances, such as a national financial
                 emergency, the Portfolio reserves the right to invest more
                 than 20% of its assets in securities other than New Jersey
                 municipal obligations. In most instances, however, the New
                 Jersey Money Market Portfolio will seek to avoid such hold-
                 ings in an effort to provide income that is fully exempt from
                 federal and New Jersey personal income taxes.

THE INSURED      Under normal circumstances, the New Jersey Insured Long-Term
LONG-TERM        Portfolio will invest at least 80% of its net assets (and 80%
PORTFOLIO        of the aggregate principal amount of all of its investments)
INVESTS IN       in insured New Jersey municipal securities.
INSURED NEW   
JERSEY           Insured municipal bonds are those in which scheduled payments
MUNICIPAL        of interest and principal are guaranteed by a private (non-
SECURITIES       governmental) insurance company. THE INSURANCE FEATURE DOES
                 NOT GUARANTEE THE MARKET VALUE OF THE MUNICIPAL BONDS OR THE
                 VALUE OF THE SHARES OF THE NEW JERSEY INSURED LONG-TERM PORT-
                 FOLIO. The insurance refers to the face or par value of the
                 securities in the Portfolio, not the market values of those
                 securities or the share price of the Portfolio. See "Imple-
                 mentation of Policies" for a description of the insurance
                 feature of the New Jersey Insured Long-Term Portfolio.
 
                 The New Jersey Insured Long-Term Portfolio 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 New Jersey Insured Long-Term Portfolio seeks to
                 invest substantially all of its assets in insured New Jersey
                 municipal obligations. However, under certain circumstances,
                 the Portfolio may invest up to 20% of its assets in any com-
                 bination of the following securities:
 
                 . Uninsured, long-term New Jersey municipal securities rated
                   a minimum of Aa by Moody's or AA by Standard & Poor's;
 
                 . Uninsured, short-term municipal securities, issued in New
                   Jersey or in other states, with the same quality standards
                   that apply for the Money Market Portfolio;
 
                 . Certain taxable fixed-income securities, including U.S.
                   Government securities; and
 
                 . Certain tax-exempt municipal securities issued by other
                   states that have similar characteristics to the securities
                   typically purchased by the Portfolio.
 
                 In such cases, a portion of the Portfolio's income may be
                 subject to New Jersey income taxes, federal income taxes, or
                 both. (See page 20).
 
                 Subject to the same 20% limit, the Portfolio is authorized to
                 invest in New Jersey AMT bonds. The income from New Jersey
                 AMT bonds is exempt from federal and New Jersey income taxes,
                 but may be a tax preference item for purposes of the federal
                 alternative minimum, see "Implementation of Policies."
 
                 Under unusual circumstances, such as a national financial
                 emergency, the Portfolio reserves the right to invest more
                 than 20% of its assets in securities other than New Jersey
                 municipal obligations. In most instances, however, the New
                 Jersey Insured Long-Term Portfolio will seek to avoid such
                 holdings in an effort to provide income that is fully exempt
                 from federal and New Jersey personal income taxes.

EACH PORTFOLIO   Although the Fund is organized as a non-diversified invest-
WILL DIVERSIFY   ment company, each Portfolio of the Fund intends to diversify
ITS HOLDINGS     its holdings of New Jersey municipal securities by com-
                 plying with Subchapter M of the Internal Revenue Code. In
                 part, Subchapter M requires that, at the close of each quar-
                 ter of the taxable year, those issues which represent more
                 than 5% of each Portfolio's assets be limited in aggregate to
                 50% of each Portfolio, and that no one issue exceed 25% of a
                 Portfolio's total assets. As of November 30, 1994, the New
                 Jersey Money Market Portfolio held securities of 39 issuers,
                 with the largest holding representing 17.6% of the Portfo-
                 lio's assets; the New Jersey Insured Long-Term Portfolio held
                 securities of 79 issuers, with the largest holding represent-
                 ing 8.67% of the Portfolio's assets.
 
                 Under New Jersey law, in order for a mutual fund to be eligi-
                 ble to pay dividends to New Jersey residents which will be
                 exempt from New Jersey personal income taxes, it must have at
                 least 80% of the aggregate principal amount of all of its in-
                 vestments, excluding financial options, futures, forward con-
                 tracts, or other similar financial instruments related to in-
                 terest-bearing obligations, obligations issued at a discount
                 or bond indexes related thereto (to the extent such instru-
                 ments are authorized by section 851(b) of the Internal Reve-
                 nue Code of 1986, as amended), cash and cash items, invested
                 in New Jersey municipal obligations (and other qualifying ob-
                 ligations). In addition, it may have no investments other
                 than interest-bearing obligations, obligations issued at a
                 discount, and cash and cash items and financial options,
                 futures, forward contracts, or other similar financial in-
                 struments related to interest-bearing obligations, obliga-
                 tions issued at a discount or bond indexes related thereto.
 
                 The Fund's policy of investing at least 80% of its assets in
                 New Jersey's municipal securities under normal circumstances
                 is fundamental and may not be changed without shareholder ap-
                 proval. The other investment policies described above are not
                 fundamental and so may be changed by the Board of Trustees
                 without shareholder approval.
--------------------------------------------------------------------------------
INVESTMENT       As mutual funds investing in municipal securities, the two
RISKS            Portfolios of the Fund are subject to both interest rate,
                 credit, call, income and manager risk. However, the risk
THE FUND IS      characteristics of the two Portfolios vary because of differ-
SUBJECT TO       ing maturity and credit quality standards.
INTEREST RATE, 
CREDIT, CALL     INTEREST RATE RISK is the potential for fluctuations in the
AND INCOME       price of a Portfolio's investments due to changing interest
RISK             rates. In general, bond prices vary inversely with interest
                 rates. If interest rates rise, bond prices generally decline;
                 if interest rates fall, bond prices generally rise. In addi-
                 tion, for a given change in interest rates, longer-maturity
                 bonds exhibit greater price fluctuations than shorter-matu-
                 rity bonds. To compensate investors for this risk, longer-ma-
                 turity bonds generally offer higher yields than shorter-matu-
                 rity bonds, other factors, including credit quality, being
                 equal. Interest rate risk may be increased or decreased when
                 a portfolio initiates or purchases derivative New Jersey mu-
                 nicipal securities. Such derivative securities rely on so-
                 phisticated interest rate calculation mechanisms. For certain
                 types of derivative bonds, the magnitude of
 
8
<PAGE>
 
                 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 portfo-
                 lio. The credit risk of a portfolio depends on the credit
                 quality of its underlying securities. In general, the lower
                 the credit quality of a portfolio's municipal securities, the
                 higher a portfolio's yield, all other factors such as matu-
                 rity being equal.
 
                 CALL RISK is the possibility that, during periods of falling
                 interest rates, a municipal security with a high stated in-
                 terest rate will be prepaid (or "called") prior to its ex-
                 pected maturity date. As a result, a portfolio will be re-
                 quired to invest the unanticipated proceeds at lower interest
                 rates, and the portfolio's income may decline. Call provi-
                 sions are most common for intermediate- and long-term munici-
                 pal bonds.
 
                 INCOME RISK is the potential for a decline in a portfolio's
                 income due to falling market interest rates. Because a port-
                 folio's income is based on interest rates, which can fluctu-
                 ate substantially over short periods, income risk is expected
                 to vary from portfolio to portfolio.
 
                    
THE FUND IS      Finally, the investment adviser manages the Fund's Portfolios
SUBJECT TO       according to the traditional methods of "active" investment
MANAGER RISK     management, which involve the buying and selling of securi-
                 ties based upon economic, financial and market analysis and
                 investment judgment. MANAGER RISK refers to the possibility
                 that the Fund's investment adviser may fail to execute a
                 Portfolio's investment strategy effectively. As a result, a
                 Portfolio may fail to achieve its stated objective.     
 
                 Given the Portfolio's stated objectives and policies, inter-
                 est rate risk for the New Jersey Money Market Portfolio is
                 expected to be negligible. The Money Market Portfolio is ex-
                 pected to maintain a stable share price of $1.00. In con-
                 trast, interest rate risk for the New Jersey Insured Long-
                 Term Portfolio may be high. The average weighted maturity of
                 the Insured Long-Term Portfolio is expected to exceed 15
                 years, meaning that the Portfolio's share price will fluctu-
                 ate, sometimes substantially, when interest rates change.
                    
                 The following chart illustrates the potential interest rate
                 risk of the New Jersey Insured Long-Term Portfolio. The chart
                 shows the market value of a $1,000 investment in a single
                 bond with the same yield and maturity characteristics as the
                 Insured Long-Term Portfolio on December 29, 1994, assuming a

                 This chart is intended to provide you with general guidelines
                 for evaluating the effect of interest rate changes on the New
                 Jersey Insured Long-Term Portfolio and determining the degree
                 of interest rate risk you may be willing to assume. The yield
                 and price changes shown are purely for illustrative purposes,
                 and should not be taken as representative of current or fu-
                 ture yields or expected changes in the share price of the In-
                 sured Long-Term Portfolio.
 
CREDIT RISK IS   Credit risk depends on the average quality of a Portfolio's
EXPECTED TO BE   underlying securities and its degree of diversification. The
LOW              New Jersey Money Market Portfolio invests primarily in high
                 quality, short-term New Jersey municipal securities, and the
                 New Jersey Insured Long-Term Portfolio invests primarily in
                 bonds insured by top-rated insurance companies against the
                 possible default of an issuer as to the timely payment of in-
                 terest and principal. As a result, the average credit quality
                 of each Portfolio is expected to be very high, and credit
                 risk is expected to be minimal.
 
                 Ordinarily, an investment company concentrating its invest-
                 ments 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 New Jersey municipal obligations.
 
                 To minimize the effects of concentrating its investments in
                 New Jersey obligations, each Portfolio of the Fund intends to
                 diversify its holdings by complying with Subchapter M of the
                 Internal Revenue Code. (See "Investment Policies" for a de-
                 scription of the requirements of Subchapter M.) In addition,
                 the high-quality instruments held by the Money Market Portfo-
                 lio and the use of municipal bond insurance in the Insured
                 Long-Term Portfolio should minimize the credit risk associ-
                 ated with the Fund.
 
                 As of November 30, 1994, top ten portfolio holdings, based on
                 market value, represented 70.62% of the Money Market Portfo-
                 lio's net assets and 36.86% of the Insured Long-Term Portfo-
                 lio's net assets.
 
                 The following chart summarizes credit, interest rate, income
                 and call risks for the Fund's Portfolios.

WHO SHOULD       The Fund is intended for New Jersey residents seeking income
INVEST           that is exempt from federal and New Jersey personal income
                 taxes. As a rule, tax-free income is attractive to investors
NEW JERSEY       in high federal and New Jersey tax brackets. You can deter-
RESIDENTS        mine whether tax-exempt or taxable income is more attractive
SEEKING TAX-     in your own case by comparing a Portfolio's tax-free yield
EXEMPT INCOME    with the yield from a comparable taxable mutual fund invest-
                 ment. See "How to Compare Tax-Free and Taxable Yields."
 
                 Assuming that tax-free income is attractive in your own tax
                 bracket, you should base your selection of a Portfolio (or
                 Portfolios) on its expected price volatility and yield, and
                 your own investment objectives, risk preferences and time ho-
                 rizon.
 
                 The NEW JERSEY MONEY MARKET PORTFOLIO is intended for invest-
                 ors who are seeking a stable share price and minimal credit
                 risk. The yield on the Portfolio is expected to fluctuate
                 from day to day and to be lower on average than the yield
                 from the New Jersey Insured Long-Term Portfolio. The New Jer-
                 sey Money Market Portfolio is suitable as a short-term in-
                 vestment vehicle, emphasizing maximum protection of princi-
                 pal.
 
                 In contrast, the NEW JERSEY INSURED LONG-TERM PORTFOLIO is
                 intended for investors who are seeking the highest, most du-
                 rable streams of income and who can tolerate sometimes sharp
                 fluctuations in share price in pursuit of their income objec-
                 tives. The yield of the Portfolio is expected to be higher,
                 and the level of income provided more stable, than that of
                 the New Jersey Money Market Portfolio. However, because of
                 the potential volatility of the Portfolio's share price, the
                 New Jersey Insured Long-Term Portfolio is appropriate only
                 for those investors who can hold their investment over the
                 long term.
 
                 The Fund is intended to be a long-term investment vehicle and
                 is not designed to provide investors with a means of specu-
                 lating on short-term market movements. Investors who engage
                 in excessive account activity generate additional costs which
                 are borne by all of the Fund's shareholders. In order to min-
                 imize 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 port-
                 folio management, either because of the timing of the invest-
                 ment or previous excessive trading by the investor. Addition-
                 ally, 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   Before choosing a specific tax-exempt investment, such as a
TAX-FREE AND     Portfolio of the Fund, you should determine if you would be
TAXABLE YIELDS   better off with taxable or tax-exempt income in your tax
                 bracket. To compare taxable and tax-free income, you should
                 first determine your combined federal, state and local tax
                 bracket. Then you should calculate the "taxable equivalent
                 yield" for the Portfolio you are considering, and compare it
                 with the yield of a taxable investment with similar credit
                 and maturity characteristics.
 
                                                                              11
<PAGE>
 
 
                 1. DETERMINE YOUR COMBINED TAX BRACKET. Your combined tax
                 bracket depends on whether you itemize state and local taxes
                 as a deduction on your federal return. If you do not itemize,
                 then your combined tax bracket is the sum of your federal,
                 state and local tax brackets.
 
                 If you do itemize, then your combined tax bracket is calcu-
                 lated as follows. First, calculate your effective state and
                 local tax bracket using the following formula:
 
                                                                   Effective
                                    Federal         State &         State &
                     ( 100%    -      Tax   )   X    Local     =     Local
                                    Bracket         Bracket         Bracket
 
                 For example, if you are in a 6.58% state and local tax
                 bracket and a 28% federal tax bracket, your effective state
                 and local tax bracket would be 4.74%:
 
                       (100% - 28%) X 6.58% = 4.74%
 
                 Second, add your effective state and local tax bracket to
                 your federal tax bracket to determine your combined tax
                 bracket:
 
                                  Effective
                     Federal       State &      Combined
                       Tax     +    Local     =   Tax
                     Bracket       Bracket      Bracket
 
                       28%     +    4.74%    =   32.74%
 
                 2. CALCULATE YOUR TAXABLE EQUIVALENT YIELD. The taxable
                 equivalent yield for a Portfolio is based upon the Portfo-
                 lio's current tax-exempt yield and your combined tax bracket.
                 The formula is:
 
                          Portfolio's Tax-Free Yield          Your Taxable
                       --------------------------------   =    Equivalent
                       100% - Your Combined Tax Bracket          Yield
 
                 For example, if you are in a combined tax bracket of 32.74%,
                 and a Portfolio's tax-free yield is 6%, the Portfolio's tax-
                 able equivalent yield would be 8.92%:
 
                                      6%           
                                 -------------     =     8.92% 
                                 100% - 32.74%
 
                 In this example, you would choose the tax-free investment if
                 the 8.92% taxable equivalent yield were greater than the tax-
                 able yield from a comparable investment (e.g., a taxable bond
                 fund of comparable maturity and credit quality).

IMPLEMENTATION   The Fund's adviser uses a variety of investment vehicles to
OF POLICIES      achieve each Portfolio's objective.     
 
THE FUND         Each Portfolio of the Fund invests principally in tax-exempt
INVESTS IN       New Jersey municipal securities, which are debt obligations
MUNICIPAL        issued by state and local governments and public financing
BONDS, NOTES     authorities (and by certain U.S. territories) that provide
AND SECURITIES   interest income which is exempt from federal and New Jersey
DERIVED FROM     personal income taxes. Municipal securities include both mu-
MUNICIPAL        nicipal bonds (those securities with maturities of five years
BONDS AND        or more) municipal notes (those securities with maturities of
NOTES            less than five years) and derivative securities (those secu-
                 rities in which a maturity may have been shortened by a de-
                 mand 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 mu-
                 nicipal 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 is-
                 suer'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. Indus-
                 trial development bonds are ordinarily dependent on the
                 credit quality of a private authority.
 
                 Municipal notes are issued to meet the short-term funding re-
                 quirements of local, regional and state governments. Munici-
                 pal notes include tax anticipation notes, bond anticipation
                 notes, revenue anticipation notes, tax and revenue anticipa-
                 tion notes, construction loan notes, short-term discount
                 notes, tax-exempt commercial paper, demand notes, and similar
                 instruments. Demand notes permit an investor (such as the
                 Fund) to demand from the issuer payment of principal plus ac-
                 crued interest upon a specified number of days' notice.
 
THE FUND MAY     Each Portfolio is authorized to invest up to 20% of its as-
INVEST IN AMT    sets in so-called "AMT" bonds. AMT bonds are tax-exempt "pri-
BONDS            vate activity" bonds issued after August 7, 1986, whose pro-
                 ceeds 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 alternative minimum tax. The alternative min-
                 imum tax is a special separate tax that applies to a limited
                 number of taxpayers who have certain adjustments to income or
                 tax preference items.
 
                                                                              13

THE FUND MAY     The Fund may invest in "Market Discount" bonds when, in the
INVEST IN        opinion of the Fund's adviser, the investment will be advan-
MARKET           tageous to the Fund's shareholders. A Market Discount bond is
DISCOUNT BONDS   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, disposi-
                 tion of a Market Discount bond will result in taxable ordi-
                 nary 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 ex-
                 pects that the purchase of these investments, on an after-tax
                 basis, will enhance the Fund's total return.     
 
THE INSURED      The New Jersey Insured Long-Term Portfolio may utilize bond
LONG-TERM        futures contracts and options to a limited extent. Specifi-
PORTFOLIO MAY    cally, the Portfolio may enter into futures contracts pro-
USE FUTURES      vided that not more than 5% of its assets are required as a
CONTRACTS AND    futures contract deposit; in addition, the Portfolio may en-
OPTIONS          ter into futures contracts and options transactions only to
                 the extent that obligations under such contracts or transac-
                 tions represent not more than 20% of the Portfolio's assets.
 
                 Futures contracts and options may be used for several rea-
                 sons: to maintain cash reserves while simulating full invest-
                 ment; to facilitate trading; and to reduce transaction costs,
                 or to seek higher investment returns when a futures contract
                 is priced more attractively than the underlying municipal se-
                 curity or index. The Portfolio may not use futures contracts
                 or options transactions to leverage its net assets.
 
                 For example, in order to simulate full investment in bonds,
                 while maintaining liquidity to meet potential shareholder re-
                 demptions, the New Jersey Insured Long-Term Portfolio may in-
                 vest a portion of its assets in a bond futures contract. Be-
                 cause futures contracts only require a small initial margin
                 deposit, the Portfolio 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 invest-
                 ing in bonds directly, it is expected that the use of futures
                 contracts and options may reduce the Portfolio's total trans-
                 action costs.
               
FUTURES          The primary risks associated with the use of futures and op-
CONTRACTS AND    tions are: (i) imperfect correlation between the change in
OPTIONS POSE     market value of the bonds held by the Portfolio and the
CERTAIN RISKS    prices of futures and options; and (ii) possible lack of a
                 liquid secondary market for a futures contract and the re-
                 sulting inability to close a futures position prior to its
                 maturity date. The risk of imperfect correlation will be min-
                 imized by investing in those contracts whose price fluctua-
                 tions are expected to resemble those of the Portfolio's un-
                 derlying securities. The risk that the Portfolio will be un-
                 able to close out a futures position will be minimized by en-
                 tering into such transactions on a national exchange with an
                 active and liquid secondary market. In general, the futures
                 market is more liquid than the
 
14
<PAGE>
 
                 municipal bond market; therefore, the Portfolio's liquidity
                 may be improved by investing in futures.
 
                 The risk of loss in trading futures contracts in some strate-
                 gies 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, a Portfolio will segregate cash or cash
                 equivalents in the amount of the underlying obligation.
 
DERIVATIVE       Derivative securities represent the purchaser's right to re-
SECURITIES       ceive principal and interest payments from underlying bonds.
                 A Fund may purchase a derivative security from another port-
                 folio within the Vanguard Group, as permitted by the Invest-
                 ment Company Act of 1940 and applicable rules thereunder, or
                 from an outside financial institution. There are different
                 derivative structures. An example of the steps involved in
                 creating and using a derivative structure follows: 1) a de-
                 positor places the underlying bond into a trust supervised by
                 an independent party; 2) a financial institution provides the
                 purchasers the right, at periodic intervals, to tender the
                 derivative security; 3) the financial institution receives
                 the difference between the prevailing short-term interest
                 rate (which is paid to the Portfolio holding the derivative
                 security) and the coupon on the underlying bond in considera-
                 tion for providing the tender option; and 4) the tender op-
                 tion may be discontinued upon the occurrence of certain
                 events, in which case, the Fund which owns the derivative se-
                 curity should receive its proportional share of the under-
                 lying bond. The primary risks associated with the use of de-
                 rivative securities are the interest rate risks discussed un-
                 der "Investment Risks," the possible lack of a liquid second-
                 ary market, the risk that the other party in a contractual
                 derivative agreement cannot meet its obligations and the po-
                 tential for greater price volatility relative to the under-
                 lying security on which the derivative is based.
 
                 The Portfolios intend to limit the risk of derivative securi-
                 ties by purchasing only those derivative securities that are
                 consistent with a Portfolio's investment objectives and poli-
                 cies. The Portfolios will not use such instruments to lever-
                 age securities. Hence, derivative securities' contributions
                 to the overall market risk characteristics of a Portfolio
                 will not materially alter its risk profile and will be fully
                 representative of the Portfolio's maturity guidelines.
                        
THREE TYPES OF   To provide an added level of credit protection, the New Jer-
INSURANCE MAY    sey Insured Long-Term Portfolio purchases securities which
BE USED IN THE   have one of the following types of insurance: new issue, mu-
INSURED LONG-    tual fund and secondary market insurance. A new issue insur-
TERM PORTFOLIO   ance policy is purchased by a bond issuer who wishes to in-
                 crease 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 secu-
                 rity (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.
 
 
                                                                              15

                 A mutual fund insurance policy may be used to guarantee spe-
                 cific bonds only while owned by a mutual fund. The Insured
                 Long-Term Portfolio of the Fund has obtained a mutual fund
                 insurance policy from Financial Guaranty Insurance Company
                 ("Financial Guaranty"), a AAA-rated insurance company. Based
                 upon the expected composition of the Portfolio, the annual
                 premiums for the policy are likely to range from 0.20% to
                 0.40% of the principal value of the bonds insured under the
                 policy, thereby reducing the Portfolio's current yield.
 
                 A secondary market insurance policy is purchased by an in-
                 vestor (such as the Insured Long-Term Portfolio) subsequent
                 to the bond's original issuance and generally insures a par-
                 ticular bond for the remainder of its term. The Portfolio may
                 purchase bonds which have already been insured under a sec-
                 ondary market insurance policy by a prior investor, or the
                 Portfolio may itself purchase such a policy from Financial
                 Guaranty for bonds that are currently uninsured.
 
                 An insured municipal bond in the Portfolio will typically be
                 covered by only one of the three policies. For instance, if a
                 bond is already covered by a new issue insurance policy or a
                 secondary market insurance policy, then that security will
                 not be insured under the Portfolio's mutual fund insurance
                 policy. All of the insurance policies used by the Portfolio
                 will be obtained only from insurance companies rated Aaa by
                 Moody's or AAA by Standard & Poor's.
 
THE INSURED      Each Portfolio of the Fund observes strict maturity guide-
LONG-TERM        lines as set forth in detail under "Investment Policies."
PORTFOLIO MAY    These maturity standards are specified in terms of a Portfo-
REPORT AN        lio's average weighted maturity. From time to time, however,
EFFECTIVE        the Fund may also report an effective average weighted matu-
AVERAGE          rity for the Insured Long-Term Portfolio, which reflects,
WEIGHTED         among other items, the likelihood that a municipal bond or
MATURITY         note held by the Portfolio may be redeemed or "called" prior
                 to its stated maturity date. For example, if the Portfolio
                 consists entirely of 20-year bonds, some of which may be
                 "called" prior to their stated maturity in 20 years, the
                 Portfolio's average weighted maturity will be 20 years, while
                 its effective average maturity will be shorter.
 
                 A Portfolio's effective average weighted maturity will be in-
                 fluenced by bond market conditions, and so may vary from day
                 to day, even if no change has been made to the Portfolio's
                 underlying investment securities. For example, if interest
                 rates decline, a greater proportion of a Portfolio's securi-
                 ties may be subject to call (redemption) prior to their
                 stated maturity. As a result, reflecting this increased call
                 risk, the effective average maturity of the Portfolio will
                 shorten, independent of actual purchases or sales of portfo-
                 lio securities.
 
                    
TEMPORARY        Except as described on Page 7, each Portfolio will not invest
INVESTMENTS      in securities other than municipal bonds except that each
                 Portfolio may make temporary investments for defensive pur-
                 poses 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     
 
16
<PAGE>
 
                 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     Each Portfolio may purchase tax-exempt securities on a "when-
PURCHASE WHEN-   issued" basis. In buying "when-issued" securities, a Portfo-
ISSUED           lio commits to buy securities at a certain price even though
SECURITIES       the securities may not be delivered for up to 45 days. The
                 Portfolio pays for the securities and begins earning interest
                 when the securities are actually delivered. As a consequence,
                 it is possible that the market price of the securities at the
                 time of delivery may be higher or lower than the purchase
                 price.
 
THE FUND MAY     Each Portfolio may lend its investment securities to quali-
LEND ITS         fied institutional investors for either short-term or long-
SECURITIES       term purposes of realizing additional net investment income.
                 Loans of securities by a Portfolio will be collateralized by
                 cash, letters of credit, or securities issued or guaranteed
                 by the U.S. Government or its agencies. The collateral will
                 equal at least 100% of the current market value of the loaned
                 securities. Income derived from the lending of securities is
                 not tax-exempt, and a portion of the tax-exempt interest
                 earned when a municipal security is on loan must be charac-
                 terized as taxable income. Therefore, each Portfolio will
                 limit such activity in accordance with its investment objec-
                 tive.
 
THE FUND MAY     Each Portfolio may purchase municipal lease obligations,
INVEST IN        which are securities issued by state and local governments to
MUNICIPAL        acquire land, equipment and facilities. These obligations
LEASE            typically are not backed by the issuing municipality's full
OBLIGATIONS      authority to assess taxes to meet its debt obligations. If
                 the issuing authority fails to make the appropriations neces-
                 sary to cover lease payments, then the lease may terminate,
                 with the possibility of default on the lease obligation and
                 loss to investors.
--------------------------------------------------------------------------------
INVESTMENT       The Fund has adopted certain limitations designed to reduce
LIMITATIONS      its exposure to specific situations. These limitations in-
                 clude the following:
 
THE FUND HAS     (a) The New Jersey Insured Long-Term Portfolio will invest a
ADOPTED              minimum of 80% of its net assets in insured municipal
CERTAIN              bonds, the interest on which is exempt from federal and
FUNDAMENTAL          New Jersey personal income taxes except that it may make
LIMITATIONS          temporary investments except as described in the section
                     "Implementation of Policies".
 
                 (b) The New Jersey Money Market Portfolio will invest a mini-
                     mum of 80% of its net assets in short-term municipal se-
                     curities, the interest on which is exempt from federal
                     and New Jersey personal income taxes except that it may
                     make temporary investments as described on the section
                     "Implementation of Policies".
 
                 (c) At the close of each quarter of the taxable year, those
                     issues which represent more than 5% of a Portfolio's as-
                     sets will be limited in aggregate to 50% of the assets of
                     that Portfolio (except U.S. Government and cash items, as
                     defined in the Internal Revenue Code).
 
 
                                                                              17
<PAGE>
 
                 (d) Each Portfolio will limit the aggregate value of holdings
                     of a single issuer (except U.S. Government and cash items
                     as defined in the Code) to a maximum of 25% of the Port-
                     folio's total assets. For the purposes of this limita-
                     tion, identification of the issuer will be based on a de-
                     termination of the source of assets and revenues commit-
                     ted to meeting interest and principal payments on each
                     security.
 
                 (e) A Portfolio will not borrow money except for temporary or
                     emergency purposes, and then not in excess of 10% of the
                     Portfolio's total assets. The Portfolio will repay all
                     borrowings before making additional investments, and the
                     interest paid on such borrowings will reduce income.
 
                 (f) A Portfolio will not pledge, mortgage, or hypothecate
                     more than 10% of its total assets.
 
                 These investment limitations are considered at the time in-
                 vestment 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 is a member of The Vanguard Group of Investment Com-
THE FUND         panies, a family of more than 30 investment companies with
                 more than 80 distinct investment portfolios and total assets
VANGUARD         in excess of $130 billion. Through their jointly-owned sub-
ADMINISTERS AND  sidiary, The Vanguard Group, Inc. ("Vanguard"), the Fund and
DISTRIBUTES THE  the other funds in the Group obtain at cost virtually all of
FUND             their corporate management, administrative, shareholder ac-
                 counting 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 1994, the aver-
                 age expense ratio (annual costs including advisory fees di-
                 vided by total net assets) for the Vanguard funds amounted to
                 approximately .30% compared to an average of 1.05% 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 Board of Trustees. The Trustees
                 set broad policies for the Fund and choose its Officers. A
                 list of the 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 Addi-
                 tional Information.
 
                 Vanguard employs a supporting staff of management and admin-
                 istrative personnel needed to provide the requisite services
                 to the funds and also furnishes the funds with necessary of-
                 fice 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.

INVESTMENT       The two Portfolios of the Fund receive all investment advi-

MANAGES THE      lios, both taxable and tax-exempt. Total assets under manage-
FUND'S           ment by Vanguard's Fixed Income Group were $55 billion as of
INVESTMENTS      December 31, 1994. The Fixed Income Group is supervised by
                 the Officers of the Fund. Ian A. MacKinnon, Senior Vice Pres-
                 ident of Vanguard, has been in charge of the Group since its
                 inception in 1981.
 
                 . David Hamlin, Assistant Vice President of Vanguard, serves
                   as portfolio manager of the New Jersey Insured Long-Term
                   Portfolio. Mr. Hamlin has managed the Portfolio since its
                   inception in 1988. Prior to joining Vanguard, Mr. Hamlin
                   managed tax-exempt money market funds for a major invest-
                   ment company. During the period of April 1992-January 1994,
                   the portfolio was managed by Reid Smith of the Fixed Income
                   Group. For 3 years prior to joining Vanguard, Mr. Smith was
                   associated with another mutual fund advisory firm as a
                   fixed-income portfolio manager.
 
                 The Fixed Income Group manages the investment and reinvest-
                 ment of the assets of the Fund's Portfolios and continuously
                 reviews, supervises and administers each Portfolio's invest-
                 ment program, subject to the maturity and quality standards
                 specified in this Prospectus and supplemental guidelines ap-
                 proved by the Fund's Board of Trustees. The Fixed Income
                 Group's selection of investments for the Portfolios is based
                 on: (a) continuing credit analysis of those instruments held
                 in the Portfolios and those being considered for inclusion
                 therein; (b) possible disparities in yield relationships be-
                 tween different fixed-income securities and money market in-
                 struments; 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 se-
                 curities are made either directly from the issuer or from mu-
                 nicipal securities dealers. The Fixed Income Group may sell
                 portfolio securities prior to their maturity if circumstances
                 and considerations warrant and if it believes such disposi-
                 tions advisable. The Fund's policy of investing in short-term
                 instruments in the New Jersey Money Market Portfolio will
                 likely result in significant portfolio turnover. The Fixed
                 Income Group seeks to obtain the best available net price and
                 most favorable execution for all portfolio transactions.

                 In addition, in order to satisfy certain distribution re-
                 quirements of the Tax Reform Act of 1986, each Portfolio may
                 declare special year-end dividend and capital gains distribu-
                 tions during December. Such distributions, if received by
                 shareholders by January 31, are deemed to have been paid by
                 the Portfolio and received by the shareholders by December 31
                 of the prior year.
 
DIVIDENDS WILL   Each Portfolio of the Fund intends to continue to qualify for
BE EXEMPT FROM   taxation as a "regulated investment company" under the Inter-
FEDERAL AND      nal Revenue Code so that each Portfolio will not be subject
NEW JERSEY       to federal income tax to the extent that its income is dis-
INCOME TAXES     tributed to shareholders. In addition, each Portfolio intends
                 to invest a sufficient portion of its assets in municipal
                 bonds and notes so that it will qualify to pay "exempt-inter-
                 est dividends" to shareholders. Such exempt-interest divi-
                 dends are excluded from a shareholder's gross income for fed-
                 eral 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 in-
                 come. Accordingly, to the extent that the Fund purchases such
                 discounted securities, taxable income may result. Further-
                 more, each Portfolio expects to invest at least 80% of the
                 aggregate principal amount of all of its investments in New
                 Jersey municipal securities. As a result, each Portfolio will
                 be eligible to pay dividends to New Jersey residents that
                 will be exempt from New Jersey personal income taxes.
 
                 Net long-term capital gains realized by a portfolio from the
                 sale of securities will be distributed as taxable capital
                 gains distributions. Any short-term capital gains or any tax-
                 able interest income will be distributed as a taxable ordi-
                 nary dividend distribution. In general, such taxable income
                 distributions from a Portfolio are expected to be negligible
                 in comparison with tax-exempt dividends. However, under cer-
                 tain circumstances, a Portfolio may invest in securities
                 other than New Jersey municipal obligations. In such cases, a
                 portion of the Portfolio's income may be subject to New Jer-
                 sey income taxes, federal income taxes, or both.
                    
                 At present, only the Money Market Portfolio invests in AMT
                 bonds. When a Portfolio invest in such bonds, a portion of
                 the Portfolio's dividends, while exempt from the regular fed-
                 eral income tax, would be a tax preference item for purposes
                 of the federal alternative minimum tax.

A CAPITAL GAIN   A sale of shares in the Insured Long-Term Portfolio is a tax-
OR LOSS MAY BE   able event and may result in a capital gain or loss. A capi-
REALIZED UPON    tal gain or loss may be realized from an ordinary redemption
EXCHANGE OR      of shares, a checkwriting redemption, or an exchange of
REDEMPTION       shares between two mutual funds (or two portfolios of a mu-
                 tual fund). In addition, if you held shares in the Insured
                 Long-Term Portfolio for six months or less, any capital loss
                 realized upon redemption is disallowed to the extent of the
                 tax-exempt dividend income you received.
 
                 Capital gains distributions from a Portfolio and any capital
                 gains or losses realized from the sale or exchange of shares
                 may also be subject to state and local taxes.
 
                 The Fund is required to withhold 31% of any taxable divi-
                 dends, capital gains distributions, and redemptions paid to
                 shareholders who have not complied with IRS taxpayer identi-
                 fication regulations. You may avoid this withholding require-
                 ment by indicating your proper Social Security or Taxpayer
                 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, to-
                 tal tax-exempt income, including any tax-exempt dividend in-
                 come from Portfolios of 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 in-
                 vestment in the Fund.

THE SHARE        The share price or "net asset value" per share of each Port-
PRICE OF EACH    folio is computed daily by dividing the total value of the
PORTFOLIO        investments and other assets of each Portfolio, less any lia-
                 bilities, by the total outstanding shares of such Portfolio.
 
                 NEW JERSEY MONEY MARKET PORTFOLIO. For the purpose of calcu-
                 lating the New Jersey Money Market Portfolio's net asset
                 value per share, securities are valued by the "amortized
                 cost" method of valuation, which does not take into account
                 unrealized gains or losses. This involves valuing an instru-
                 ment at its cost and thereafter assuming a constant amortiza-
                 tion to maturity of any discount or premium, regardless of
                 the impact of fluctuating interest rates on the market value
                 of the instrument. While this method provides certainty in
                 valuation, it may result in periods during which value, as
                 determined by amortized cost, is higher or lower than the
                 price the Portfolio would receive if it sold the instrument.
 
                 The use of amortized cost and the maintenance of the New Jer-
                 sey Money Market Portfolio's per share net asset value at
                 $1.00 is based on its election to operate
 
                                                                              21

                 under the provisions of Rule 2a-7 under the Investment Com-
                 pany Act of 1940. As a condition of operating under that
                 rule, the New Jersey Money Market Portfolio must maintain a
                 dollar-weighted average portfolio maturity of 90 days or
                 less, purchase only instruments having remaining maturities
                 of 13 months or less, and invest only in securities that are
                 determined by the Trustees to present minimal credit risks
                 and that are of high quality as determined by any major rat-
                 ing service, or in the case of any instrument not so rated,
                 considered by the Trustees to be of comparable quality.
 
                 The Trustees have established procedures designed to stabi-
                 lize the net asset value per share as computed for the pur-
                 poses of sales and redemptions at $1.00. These procedures in-
                 clude periodic review, as the Trustees deem appropriate and
                 at such intervals as are reasonable in light of current mar-
                 ket conditions, of the relationship between the amortized
                 cost value per share and a net asset value per share based
                 upon available indications of market value. In such a review,
                 investments for which market quotations are readily available
                 are valued at the most recent bid price or quoted yield
                 equivalent for such securities or for securities of compara-
                 ble maturity, quality and type as obtained from one or more
                 of the major market makers for the securities to be valued.
                 Other investments and assets are valued at fair value, as de-
                 termined in good faith by the Trustees.
 
                 In the event of a deviation of over 1/2 of 1% between a Port-
                 folio's net asset value based upon available market quota-
                 tions or market equivalents and $1.00 per share based on am-
                 ortized cost, the Trustees will promptly consider what ac-
                 tion, if any, should be taken. The Trustees will also take
                 such action as they deem appropriate to eliminate or to re-
                 duce, to the extent reasonably practicable, any material di-
                 lution or other unfair results to investors or existing
                 shareholders which might arise from differences between the
                 two. Such action may include redeeming shares in kind, sell-
                 ing instruments prior to maturity to realize capital gains or
                 losses or to shorten average maturity, withholding dividends,
                 paying distributions from capital or capital gains, or util-
                 izing a net asset value per share based upon available market
                 quotations.
 
                 NEW JERSEY INSURED LONG-TERM PORTFOLIO. The net asset value
                 per share of the New Jersey Insured Long-Term Portfolio is
                 determined at the close of regular trading on the Exchange
                 each day the Exchange is open for business. When approved by
                 the Board of Trustees, bonds and other fixed-income securi-
                 ties of each of the Portfolios may be valued on the basis of
                 prices provided by a pricing service when such prices are be-
                 lieved to reflect the fair market value of such securities.
                 (The prices provided by pricing services are generally deter-
                 mined 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 develop-
                 ments related to specific securities.) The methods used by
                 the pricing service and the valuations so established are re-
                 viewed by the Officers of the Fund under the general supervi-
                 sion of the Trustees.

                 There are a number of pricing services available and the
                 Trustees, on the basis of ongoing evaluation of these servic-
                 es, 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 valua-
                 tion date may be valued at cost, plus or minus any amortized
                 discount or premium. Other assets and securities for which no
                 quotations are readily available will be valued in good faith
                 at their fair value using methods determined by the Trustees.
                     
                 The price per share of the Insured Long-Term Portfolio can be
                 found daily in the mutual fund section of most major newspa-
                 pers under the heading of The Vanguard Group.

                 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

--------------------------------------------------------------------------------
TAX CAUTION      Under Federal tax laws, the Fund is required to distribute
                 net capital gains and investment income to Fund shareholders.
INVESTORS        These distributions are made to all shareholders who own Fund
SHOULD ASK       shares as of the distribution's record date, regardless of
ABOUT THE        how long the shares have been owned. Purchasing shares just
TIMING OF        prior to the record date could have a significant impact on
CAPITAL GAINS    your tax liability for the year. For example, if you purchase
AND DIVIDEND     shares immediately prior to the record date of a sizable cap-
DISTRIBUTIONS    ital gain, you will be assessed taxes on the amount of the
BEFORE           capital gain distribution later paid even though you owned
INVESTING        the Fund shares for just a short period of time. (Taxes are
                 due on the distributions even if the capital gain is rein-
                 vested in additional Fund shares.) While the total value of
                 your investment will be the same after the capital gain dis-
                 tribution--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 poten-
                 tial distributions before investing. The Fund's annual capi-
                 tal gains distribution normally occurs in December, while in-
                 come dividends are generally paid on the first business day
                 of each month. For additional information on distributions
                 and taxes, see the section titled "Dividends, Capital Gains,
                 and Taxes."

WHEN YOUR        The trade date is the date on which your account is credited.
ACCOUNT WILL     It is generally the day on which the Fund receives your in-
BE CREDITED      vestment in the form of Federal Funds (monies credited to the
                 Fund's Custodian Bank by a Federal Reserve Bank). Your trade
                 date varies according to your method of payment for your
                 shares.
                    
                 Purchases of Fund shares by check (except the Money Market
                 Portfolio) will receive a trade date the day the funds are
                 received in good order by Vanguard. Thus, if your purchase by
                 check is received by the close of regular trading on the New
                 York Stock Exchange (generally 4:00 p.m. Eastern time), your
                 trade date is the business day your check is received in good
                 order. If your purchase is received after the close of the
                 exchange your trade date is the business day following re-
                 ceipt of your check. Vanguard will not accept third-party
                 checks to open an account. Please be sure your purchase check
                 is made payable to the Vanguard Group.     
 
                 For purchases by check for the Money Market Portfolio, the
                 Fund is ordinarily credited with Federal Funds within one
                 business day. Thus, if your purchase by check is received by
                 the close of the New York Stock Exchange (generally 4:00 p.m.
                 Eastern time), your trade date is the business day following
                 receipt of your check. If your purchase is received after the
                 close of the Exchange, your trade date is the second business
                 day following receipt of your check.
 
                 For purchases by Federal Funds wire or exchange, the Fund is
                 credited immediately with Federal Funds. Thus, if your pur-
                 chase by Federal Funds wire or exchange is received by the
                 close of the Exchange your trade date is the day of receipt.
                 If your purchase is received after the close of the Exchange,
                 your trade date is the business day following receipt of your
                 wire or exchange.
 
                 Your shares are purchased at the net asset value determined
                 on your trade date. You will begin to earn dividends on the
                 calendar day following the trade date. (For a Friday trade
                 date, you will begin earning dividends on Saturday.) For a
                 purchase of the Money Market Portfolio by Federal Funds wire,
                 you may qualify for a dividend on the date of purchase if you
                 have notified the Fund of your
 
                                                                              27

                 intention to make the purchase by 10:45 a.m. (Eastern time)
                 on the business day of the wire.
 
                 In order to prevent lengthy processing delays caused by the
                 clearing of foreign checks, Vanguard will only accept a for-
                 eign 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 BY       You may withdraw funds from your account by writing a check
WRITING A        payable in the amount of $250 or more. When a check is pre-
CHECK            sented 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 ac-
                 count, 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
                 clearance. CORPORATIONS, TRUSTS AND OTHER ORGANIZATIONS
                 SHOULD CALL 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.
                 3. Vanguard cannot guarantee a stop payment on any check. If
                    you wish to reverse a stop payment order, you must do so
                    in writing.
                 4. Shares held in certificate form cannot be redeemed using
                    the checkwriting option.
                 5. The Fund reserves the right to terminate or alter this
                    service at any time.

                 States Securities and Exchange Commission.
                 --------------------------------------------------------------
VANGUARD'S       If you make a redemption from a qualifying account, Vanguard
AVERAGE COST     will send you an Average Cost Statement which provides you
STATEMENT        with the tax basis of the shares you redeemed. Please see
                 "Other Vanguard Services" for additional information.
                 --------------------------------------------------------------
MINIMUM          Due to the relatively high cost of maintaining smaller ac-
ACCOUNT          counts, the Fund reserves the right to redeem shares in any
BALANCE          account that is below the minimum initial investment amount
REQUIREMENT      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 ac-
                 count is below the Fund's minimum account balance require-
                 ment. 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.
 
                 The Fund's minimum account balance requirement will not apply
                 if your account falls below $3,000 solely as a result of de-
                 clining markets (i.e., a decline in a Portfolio's net asset
                 value).

                 --------------------------------------------------------------
IMPORTANT        Before you make an exchange, you should consider the follow-
EXCHANGE         ing:
INFORMATION 
                 . Please read the Fund's prospectus before making an ex-
                   change. For a copy and for answers to any questions you may
                   have, call our Investor Information Department (1-800-662-
                   7447).
 
                 . An exchange is treated as a redemption and a purchase.
                   Therefore, you could realize a taxable gain or loss on the
                   transaction.
 
                 . Exchanges are accepted only if the registrations and the
                   Taxpayer Identification numbers of the two accounts are
                   identical.
 
                 . The shares to be exchanged must be on deposit and not held
                   in certificate form.
 
                 . New accounts are not currently accepted in Vanguard/Windsor
                   Fund or Vanguard/PRIMECAP Fund.
 
                 . The redemption price of shares redeemed by exchange is the
                   net asset value next determined after Vanguard has received
                   the required documentation in Good Order.
 
                 . When opening a new account by exchange, you must meet the
                   minimum investment requirement of the new Fund.
 
 
                                                                              31

                 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 New Jersey, the
                 only state in which the Fund's shares are registered for
                 sale.
--------------------------------------------------------------------------------
EXCHANGE         The Fund's exchange privilege is not intended to afford
PRIVILEGE        shareholders a way to speculate on short-term movements in
LIMITATIONS      the market. Accordingly, in order to prevent excessive use of
                 the exchange privilege that may potentially disrupt the man-
                 agement of the Fund and increase transaction costs, the Fund
                 has established a policy of limiting excessive exchange ac-
                 tivity.
 
                 Exchange activity generally will not be deemed excessive if
                 limited to TWO SUBSTANTIVE EXCHANGE REDEMPTIONS (AT LEAST 30
                 DAYS APART) from a Portfolio during any twelve month period.
                 These limitations do not apply to exchanges from Vanguard's
                 money market portfolios. Notwithstanding these limitations,
                 the Fund reserves the right to reject any purchase request
                 (including exchange purchases from other Vanguard portfolios)
                 that is reasonably deemed to be disruptive to efficient port-
                 folio management.
--------------------------------------------------------------------------------
IMPORTANT        The ability to initiate redemptions (except wire redemptions)
INFORMATION      and exchanges by telephone is automatically established on
ABOUT            your account unless you request in writing that telephone
TELEPHONE        transactions on your account not be permitted. The ability to
TRANSACTIONS     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 unautho-
                 rized or fraudulent telephone instructions, Vanguard adheres
                 to the following security procedures:
 
                 1. SECURITY CHECK. To request a transaction by telephone, the
                 caller must know (i) the name of the Portfolio; (ii) the 10-
                 digit account number; (iii) the exact name and address used
                 in the registration; and (iv) the Social Security or Employer
                 Identification number listed on the account.
 
                 2. PAYMENT POLICY. The proceeds of any telephone redemption
                 by mail will be made payable to the registered shareowner and
                 mailed to the address of record, only. In the case of a tele-
                 phone redemption by wire, the wire transfer will be made only
                 in accordance with the shareowner's prior written instruc-
                 tions.
 
                 Neither the Fund nor Vanguard will be responsible for the au-
                 thenticity of transaction instructions received by telephone,
                 provided that reasonable security procedures have been fol-
                 lowed. Vanguard believes that the security procedures de-
                 scribed 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 ac-
                 count.

                            INVESTMENT LIMITATIONS
   
  The following limitations cannot be changed without the consent of the hold-
ers of a majority of the Fund's outstanding shares (as defined in the Invest-
ment Company Act of 1940 (the "1940 Act")), including a majority of the shares
of each Portfolio.     
     
    1. Each Portfolio will limit the aggregate value of all holdings (except
  U.S. Government and cash items, as defined under Subchapter M of the Inter-
  nal Revenue Code (the "1940 Act")), each of which exceeds 5% of the Portfo-
  lio's total assets, to an aggregate amount of 50% of such assets;     
 
    2. Each Portfolio will limit the aggregate value of holdings of a single
  issuer (except U.S. government and cash items, as defined in the Code) to a
  maximum of 25% of the Portfolio's total assets. For the purposes of this
  limitation, identification of the issuer will be based on a determination
  of the source of assets and revenues committed to meeting interest and
  principal payments of each security;
 
    3. Each Portfolio will not borrow money except for temporary or emergency
  purposes and then only in an amount not exceeding 10% of the value of the
  total assets of that Portfolio. The Portfolio will repay all borrowings be-
  fore making additional investments. Interest paid on such borrowings will
  reduce income;
 
    4. Each Portfolio will not pledge, mortgage or hypothecate its assets to
  any extent greater than 10% of the value of the total assets of the Portfo-
  lio;
     
    5. Each Portfolio will not issue senior securities as defined in the 1940
  Act;     
 
                                                                            B-1
<PAGE>
 
    6. Each Portfolio will not engage in the business of underwriting securi-
  ties issued by other persons, except to the extent that the Portfolio may
  technically be deemed an underwriter under the Securities Act of 1933, as
  amended, in disposing of Portfolio securities.
 
    7. Each Portfolio will not purchase or otherwise acquire any securities,
  if as a result, more than 15% (10% with respect to the Money Market Portfo-
  lio) of its net assets would be invested in securities that are illiquid
  (included in this limitation is the Fund's investment in the Vanguard
  Group, Inc.)
 
    8. Each Portfolio will not purchase or sell real estate, but this shall
  not prevent investments in Municipal Bonds secured by real estate or inter-
  ests therein;
 
    9. Each Portfolio will not make loans to other persons, except by the
  purchase of bonds, debentures or similar obligations which are publicly
  distributed and as provided under "Lending of Securities";
 
    10. Each Portfolio will not purchase on margin or sell short, except as
  specified below in Investment Limitation No. 12;
 
    11. Each Portfolio will not purchase or retain securities of an issuer if
  those Trustees of the Fund, each of whom owns more than 1/2 of 1% of such
  securities, together own more than 5% of the securities of such issuer;
 
    12. Each Portfolio will not purchase or sell commodities or commodities
  contracts, except that the New Jersey Insured Long-Term Portfolio may in-
  vest in bond futures contracts, bond options and options on bond futures
  contracts to the extent that not more than five percent of the Portfolio's
  assets are required as deposit on futures contracts and not more than 20%
  of the Portfolio's assets are invested in futures contracts and/or options
  transactions at any time;
 
    13. Each Portfolio will not invest its assets in securities of other in-
  vestment companies except as they may be acquired as part of a merger, con-
  solidation, reorganization or acquisition of assets or otherwise, to the
  extent permitted by Section 12 of the 1940 Act;
     
    14. Each Portfolio will not invest in securities other than municipal
  bonds except that each Portfolio may make temporary investments in (a)
  notes issued by or on behalf of municipal or corporate issuers, obligations
  of the U.S. Government and its agencies, commercial paper, bank certifi-
  cates of deposit; (b) investment companies investing in such securities
  which have investment objectives consistent with those of the Portfolio to
  the extent permitted by the 1940 Act; and (c) any such securities or munic-
  ipal bonds subject to repurchase agreements.     
 
    15. Each Portfolio will not invest in put, call, straddle or spread op-
  tions (except as described above in investment limitation No. 12) or inter-
  ests in oil, gas or other mineral exploration or development programs.
 
  The above-mentioned investment limitations are considered at the time in-
vestment securities are purchased. Notwithstanding these limitations, each
Portfolio may own all or any portion of the securities of, or make loans to,
or contribute to the costs or other financial requirements of, any company
which will be (1) wholly owned by the Fund and one or more other investment
companies and (2) primarily engaged in the business of providing, at cost,
management, administrative, distribution and/or related services to the Fund
and such other investment companies. Additionally, the Fund may invest in
when-issued securities without limitation. Please see the Prospectus for a de-
scription of securities.
 
  LENDING OF SECURITIES. Each Portfolio may lend its investment securities to
qualified institutions who need to borrow securities in order to complete cer-
tain transactions, such as covering short sales, avoiding failures to deliver
securities or completing arbitrage operations. By lending its investment secu-
rities, the Portfolio attempts to increase its income through the receipt of
interest on the
 
B-2
<PAGE>
 
   
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 Portfolio.
The Portfolio may lend its investment securities to qualified brokers, deal-
ers, banks or other financial institutions, so long as the terms and the
structure of such loans are not inconsistent with the 1940 Act, or the Rules
and Regulations or interpretations of the Securities and Exchange Commission
(the "Commission") thereunder, which currently require that (a) the borrower
pledge and maintain with the Portfolio collateral having a value at all times
not less than 100% of the value of the securities loaned, (b) the borrower add
to such collateral whenever the price of the securities loaned rises (i.e.,
the borrower "marks to the market" on a daily basis), (c) the loan be made
subject to termination by the Portfolio at any time and (d) the Portfolio re-
ceive reasonable interest on the loan (which may include the Portfolio invest-
ing any cash collateral in interest bearing short-term investments), any dis-
tribution on the loaned securities and any increase in their market value. A
Portfolio will not lend its investment securities, if as a result, the aggre-
gate of such loans exceeds 10% of the value of its total assets. Loan arrange-
ments made by the Portfolio will comply with all other applicable regulatory
requirements, including the Rules of the New York Stock Exchange, which rules
presently require the borrower, after notice, to redeliver the securities
within the normal settlement time of five business days. All relevant facts
and circumstances, including the creditworthiness of the broker, dealer or in-
stitution, will be considered in making decisions with respect to the lending
of securities, subject to review by the Fund's Board of Directors. Income de-
rived from lending of securities is not tax-exempt, and, thus, a portfolio
will limit such activity in accordance with its investment objective.     
 
FUTURES CONTRACTS AND OPTIONS
 
  The Insured Long-Term Portfolio may enter into futures contracts, options,
and options on futures contracts for several reasons: to maintain cash re-
serves while simulating full investment, to facilitate trading, to reduce
transaction costs, or to seek higher investment returns when a futures con-
tract is priced more attractively than the underlying municipal security or
index. 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 Com-
modity Exchange Act by the Commodity Futures Trading Commission ("CFTC"), a
U.S. Government Agency.
 
  Although futures contracts by their terms call for actual delivery or ac-
ceptance of the underlying securities, in most cases the contracts are closed
out before the settlement date without the making or taking of delivery. Clos-
ing out an open futures position is done by taking an opposite position ("buy-
ing" a contract which has previously been "sold," or "selling" a contract pre-
viously purchased) in an identical contract to terminate the position. Broker-
age 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 comple-
tion 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. Bro-
kers 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 ex-
cess 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 ex-
pects to earn interest income on its margin deposits.
 
                                                                            B-3
<PAGE>
 
  Traders in futures contracts may be broadly classified as either "hedgers"
or "speculators." Hedgers use the futures markets primarily to offset unfavor-
able 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 con-
tracts 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 Portfolio
will only sell futures contracts to protect securities it owns against price
declines or purchase contracts to protect against an increase in the price of
securities it intends to purchase. As evidence of this hedging interest, the
Portfolio expects that approximately 75% of its futures contract purchases
will be "completed," that is, equivalent amounts of related securities will
have been purchased or are being purchased by the Portfolio upon sale of open
futures contracts.
 
  Although techniques other than the sale and purchase of futures contracts
could be used to control the Portfolio's exposure to market fluctuations, the
use of futures contracts may be a more effective means of hedging this expo-
sure. While the Portfolio will incur commission expenses in both opening and
closing out futures positions, these costs are lower than transaction costs
incurred in the purchase and sale of the underlying securities.
 
RESTRICTIONS ON THE USE OF FUTURES CONTRACTS
 
  The Portfolio will not enter into futures contract transactions to the ex-
tent that, immediately thereafter, the sum of its initial margin deposits on
open contracts exceeds 5% of the market value of the Fund's total assets. In
addition, the Portfolio will not enter into futures contracts to the extent
that its outstanding obligations to purchase securities under these contracts
would exceed 20% of the Portfolio's total assets. Assets committed to futures
contracts or options will be held in a segregated account at the Fund's custo-
dian bank.
 
RISK FACTORS IN FUTURES TRANSACTIONS
 
  Positions in futures contracts may be closed out only on an Exchange which
provides a secondary market for such futures. However, there can be no assur-
ance that a liquid secondary market will exist for any particular futures con-
tract at any specific time. Thus, it may not be possible to close a futures
position. In the event of adverse price movements, the Portfolio would con-
tinue to be required to make daily cash payments to maintain its required mar-
gin. In such situations, if the Portfolio has insufficient cash, it may have
to sell portfolio securities to meet daily margin requirements at a time when
it may be disadvantageous to do so. In addition, the Portfolio may be required
to make delivery of the instruments underlying futures contracts it holds. The
inability to close options and futures positions also could have an adverse
impact on the ability to effectively hedge it.
 
  The Portfolio will minimize the risk that it will be unable to close out a
futures contract by only entering into futures which are traded on national
futures exchanges and for which there appears to be a liquid secondary market.
The 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 sub-
stantial, 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 sub-
stantial 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
 
B-4
<PAGE>
 
transaction costs, if the account were then closed out. A 15% decrease would
result in a loss equal to 150% of the original margin deposit if the contract
were closed out. Thus, a purchase or sale of a futures contract may result in
losses in excess of the amount invested in the contract. However, because the
futures strategies of the Portfolio are engaged in only for hedging purposes,
the Adviser does not believe that the Portfolio is subject to the risks of
loss frequently associated with futures transactions. The Portfolio would pre-
sumably have sustained comparable losses if, instead of the futures contract,
it had invested in the underlying financial instrument and sold it after the
decline.
 
  Utilization of futures transactions by the Portfolio does involve the risk
of imperfect or no correlation where the securities underlying futures con-
tracts have different maturities or other characteristics than the portfolio
securities being hedged. It is also possible that the Portfolio could both
lose money on futures contracts and also experience a decline in value of its
portfolio securities. There is also the risk of loss by the Portfolio of mar-
gin deposits in the event of bankruptcy of a broker with whom the Portfolio
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 unfa-
vorable 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 Portfolios are required for federal income tax purposes to recognize as
income for each taxable year their net unrealized gains and losses on certain
futures contracts held as of the end of the year as well as those actually re-
alized during the year. In most cases, any gain or loss recognized with re-
spect 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 in-
tended to hedge against a change in the value of securities held by the Port-
folio may affect the holding period of such securities and, consequently, the
nature of the gain or loss on such securities upon disposition. A Portfolio
may be required to defer the recognition of losses on futures contracts to the
extent of any unrecognized gains on related positions held by the Portfolio.
 
  In order for the Portfolio to continue to qualify for Federal income tax
treatment as a regulated investment company, at least 90% of its gross income
for a taxable year must be derived from qualifying income; i.e., dividends,
interest, income derived from loans of securities, gains from the sale of se-
curities or of foreign currencies or other income derived with respect to the
Portfolio's business of investing in securities. In addition, gains realized
on the sale or other disposition of securities held for less than three months
must be limited to less than 30% of the Portfolio's annual gross income. It is
anticipated that any net gain realized from the closing out of futures con-
tracts will be considered gain from the sale of securities and therefore be
qualifying income for purposes of the 90% requirement. In order to avoid real-
izing excessive gains on securities held less than three months, the Portfolio
may be required to defer the closing out of futures contracts beyond the time
when it would otherwise be advantageous to do so. It is anticipated that
unrealized gains on futures contracts, which have been open for less than
three months as of the end of the Portfolio's fiscal year and which are recog-
nized for tax purposes, will not be considered gains on sales of securities
held less than three months for the purpose of the 30% test.
 
                                                                            B-5
<PAGE>
 
  The Portfolio will distribute to shareholders annually any net capital gains
which have been recognized for federal income tax purposes (including
unrealized gains at the end of the Portfolio's fiscal year) on futures trans-
actions. Such distributions will be combined with distributions of capital
gains realized on the Portfolio's other investments and shareholders will be
advised on the nature of the transactions.
 
                            YIELD AND TOTAL RETURN
 
  The yield of the New Jersey Insured Long-Term Portfolio for the 30-day pe-
riod ended November 30, 1994 was 6.28%.
   
  The average annual total return of the New Jersey Insured Long-Term Portfo-
lio for the one- and five-year periods ended November 30, 1994 was -6.10% and
+6.50%, respectively. The average annual total return of the New Jersey In-
sured Long-term Portfolio since its inception on February 3, 1988 is +7.37%.
The average annual total return of the New Jersey Money Market Portfolio for
the one- and five-year periods ended November 30, 1994 was +2.49%, and +3.63%,
respectively. The average annual total return of the New Jersey Money Market
Portfolio since its inception on February 3, 1988 was +4.20%. Total return is
computed by finding the average compounded rates of return over the period set
forth above that would equate an initial amount invested at the beginning of
the period to the ending redeemable value of the investment.     
 
                             CALCULATION OF YIELD
 
  The current yield of the New Jersey Money Market Portfolio is calculated
daily on a base period return of a hypothetical account having a beginning
balance of one share for a particular period of time (generally 7 days). The
return is determined by dividing the net change (exclusive of any capital
changes) in such account by its average net asset value for the period, and
then multiplying it by 365/7 to get the annualized current yield. The calcula-
tion of net change reflects the value of additional shares purchased with the
dividends by the Portfolio, including dividends on both the original share and
on such additional shares. An effective yield, which reflects the effects of
compounding and represents an annualization of the current yield with all div-
idends reinvested, may also be calculated for the Portfolio by adding 1 to the
net change, raising the sum to the 365/7 power, and subtracting 1 from the re-
sult.
 
  Set forth below is an example, for purposes of illustration only, of the
current and effective yield calculations for the New Jersey Money Market Port-
folio for the 7-day base period ended November 30, 1994.

  The New Jersey Money Market Portfolio seeks to maintain but does not guaran-
tee, a constant net asset value of $1.00 per share. Although the Money Market
Portfolio invests in high-quality instruments, the shares of the Portfolio are
not insured or guaranteed by the U.S. Government. The yield of the Portfolio
will fluctuate. The annualization of a week's dividend is not a representation
by the
 
B-6
<PAGE>
 
Portfolio as to what an investment in the Portfolio will actually yield in the
future. Actual yields will depend on such variables as investment quality, av-
erage maturity, the type of instruments the Portfolio invests in, changes in
interest rates on instruments, changes in the expenses of the Fund and other
factors. Yields are one basis investors may use to analyze the Portfolios of
the Fund, and other investment vehicles, however, yields of other investment
vehicles may not be comparable because of the factors set forth in the preced-
ing sentence, differences in the time periods compared, and differences in the
methods used in valuing portfolio instruments, computing net asset value and
calculating yield.

                RISK FACTORS VANGUARD NEW JERSEY TAX-FREE FUND
 
  The Vanguard New Jersey Tax-Free Fund invests primarily in the obligations
of New Jersey state government and various local governments, including coun-
ties, cities, special districts, agencies 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.
 
B-8
<PAGE>
 
  Measured against these criteria, the credit risk associated with direct ob-
ligations of the State of New Jersey and State agencies, including general ob-
ligation and revenue bonds, and lease debt, compares very favorably. For most
of the last two decades, the State's general obligation bonds have enjoyed the
highest rating by either Moody's Investors Service or Standard & Poor's. In
the early 1990's, however, both Moody's and Standard & Poors both slightly
downgraded the state's credit rating to the high "AA" level due to an economy
and state finances weakened by recession. In general, New Jersey's high credit
quality over time reflects the strong growth and diversification of its econo-
my, a moderate debt position, wealth levels much higher than the national av-
erage, and a historically sound and stable financial position.
 
  New Jersey's economy continues to gradually emerge from the depths of the
1990-92 national recession. Between 1989 and 1992, the state lost 8.7 percent
of its employment total or about one job in 12. Significant job losses oc-
curred in the construction, manufacturing, wholesale and retail trades, and in
financial and real estate services. The only sectors to experience growth dur-
ing the period were the healthcare and government sectors. Unemployment rates
exceeded the national averages and reached a high of 9.8% in July of 1992.
Economic variables indicate a slowly improving New Jersey economy, as evi-
denced by a decrease in the unemployment rate for 1993. However, this progress
could be mitigated by layoffs in the pharmaceutical industry and AT&T, New
Jersey's largest employer.
 
  The most recent cyclical weakening of the New Jersey economy follows an un-
precedented period of diversification and growth for the state in the 1980's.
Like many other northeastern and "rust-belt" states, New Jersey's economy de-
clined during the 1970s. This set the stage for a remarkable period of trans-
formation in the 1980s. The State economy changed from a manufacturing-domi-
nated base to an economy balanced among manufacturing, trade and services,
closely mirroring the U.S. economy. Population growth exceeded the regional
average during this time, and growth in employment and income outpaced the
U.S. average. This growth occurred not only in the developed northeastern and
Delaware River Valley areas, but also in central New Jersey around Princeton
and the Atlantic coastal region. Despite the recession of 1990 to 1992, New
Jersey remains a wealthy state, and continues to be the second wealthiest af-
ter Connecticut. Per capita state income is over a third higher than the U.S.
average.
 
  The State's debt burden is moderate in relation to the state's wealth and
resources, but has increased significantly since 1991 as the state has fi-
nanced capital outlays previously funded out of current revenues and stepped
up debt issuance to stimulate a weakened economy. Tax-supported debt as mea-
sured against income and population is close to average levels among the
states. Debt retirement is rapid even though debt service has a modest claim
on State revenues. New debt issuance is expected to be manageable.
 
  After a decade of sound financial operations in the 1980's, characterized by
robust increases in revenues and fund balances, the State has now faced four
years of budgetary distress which remains to be resolved. Declining tax reve-
nues and swelling expenditures for Medicaid, public assistance, and correc-
tions have generated repeated budget gaps that the State has been able to
close only by utilizing non-recurring revenue sources. Stabilization of the
state's fiscal situation could be hampered by newly-elected Governor Christine
Todd Whitman's pledge to cut state taxes by 30 percent over three years. Con-
tinued high credit quality will depend on the resolve of State leaders and
taxpayers to maintain fiscal balance while diminishing a reliance on one-time
revenue sources.
 
  A positive credit factor for local governments in New Jersey is the strong
State oversight of local government operations. The State can and has seized
control of mismanaged jurisdictions. In general, the high level of wealth and
the strong economic base in the State have resulted in credit quality for lo-
cal government that is among the highest in the U.S. In addition, the State
guarantees the debt
 
                                                                            B-9

service of many local government bond issues. As state finances remain under
pressure, however, local governments may see levels of state aid reduced, a
development that could result in a dilution of local credit quality. Success-
ful tax appeals by property owners in many municipalities have also reduced
revenues for some local governments.
 
  Despite the strengths of New Jersey credit quality, there are risks. New
Jersey has a number of older urban centers, including Newark and Camden, that
present a continuing vulnerability with respect to economic and social prob-
lems. The State is facing educational finance reforms which could affect the
credit quality of certain school districts as well as state financial opera-
tions. In addition, health-care and welfare reform proposals must be addressed
in the coming fiscal year. State taxes were increased in 1990 to balance the
State's budget and then reduced in 1992 after a "taxpayer revolt" reversed the
political power balance in the state legislature. Finally, overbuilding in the
residential and commercial real estate sector has weakened property values as
well as the general health of the construction industry and related financial
institutions.
 
                             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 speci-
fied standards; making changes in specific issues in light of changes in the
fundamental basis for purchasing such securities; and adjusting the Fund to
meet cash inflow (or outflow), which reflects net purchases and exchanges of
shares by investors (or net redemptions of shares) and reinvestment of the
Fund's income.
 
  A change in securities held by the Fund is known as "portfolio turnover" and
may involve the payment of the Fund of dealer mark-ups, underwriting commis-
sions and other transaction costs on the sales of securities as well as on the
reinvestment of the proceeds in other securities. The annual portfolio turn-
over rate for each of the Fund's portfolios is set forth under the heading
"Financial Highlights" in the New Jersey Tax-Free Fund prospectus. The portfo-
lio 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 offer-
ing of its shares, (ii) to reject purchase orders when in the judgment of man-
agement such rejection is in the best interest of the Fund, and (iii) to re-
duce or waive the minimum for initial and subsequent investments under circum-
stances where certain economies can be achieved in sales of the Fund's shares.
 
  STOCK CERTIFICATES. Your purchase will be made in full and fractional shares
of the Fund calculated to three decimal places. Shares are normally held on
deposit for shareholders by the Fund, which will send to shareholders a state-
ment of shares owned at the time of each transaction. This saves the share-
holders the trouble of safekeeping the certificates and saves the Fund the
cost of issuing certificates. Share certificates are, of course, available at
any time upon written request at no additional cost to shareholders. No cer-
tificates will be issued for fractional shares.

                             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 rea-
sonably 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 confor-
mity 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 be sure that you are the person who has autho-
rized a redemption from your account. Signature guarantees are required in
connection with: (1) redemptions involving more than $25,000 on the date of
receipt by Vanguard of all necessary documents; (2) all redemptions, regard-
less of the amount involved, when the proceeds are to be paid to someone other
than the registered owners); and (3) share transfer requests.
 
  A signature guarantor may be obtained from banks, brokers and any other
guarantor institution that Vanguard deems acceptable.
 
  The signature guarantees must appear either: (1) on the written request for
redemption, (2) on a separate instrument for assignment ("stock power") which
should specify the total number of shares to be redeemed, or (3) on all stock
certificates tendered for redemption and, if shares held by the Fund are also
being redeemed, on the letter or stock power.
 
                              VALUATION OF SHARES
 
  The valuation of shares of the New Jersey Insured Long-Term Portfolio is de-
scribed in detail in the Prospectus.
 
  NEW JERSEY MONEY MARKET PORTFOLIO. The net asset value per share of the New
Jersey Money Market Portfolio is determined on each day that the New York
Stock Exchange is open and on any other day on which there is sufficient trad-
ing in the Fund's securities to materially affect the Fund's net asset value
per share.
 
  It is the policy of the New Jersey Money Market Portfolio to attempt to
maintain a net asset value of $1.00 per share for purposes of sales and re-
demptions. The New Jersey Money Market Portfolio seeks to maintain, but does
not guarantee a constant net asset value of $1.00 per share. Although the New
Jersey Money Market Portfolio invests in high-quality instruments, the shares
of the Portfolio are not insured or guaranteed by the U.S. Government. The in-
struments held by the New Jersey Money Market Portfolio are valued on the ba-
sis of amortized cost which does not take into account unrealized capital
gains or losses. This involves valuing an instrument at-cost and thereafter
assum-
 
                                                                           B-11
<PAGE>
 
ing a constant amortization to maturity of any discount or premium, regardless
of the impact of fluctuating interest rates on the market value of the instru-
ment. While this method provides certainty in valuation, it may result in pe-
riods during which value, as determined by amortized cost, is higher or lower
than the price the Portfolio would receive if it sold the instrument. During
periods of declining interest rates, the daily yield on shares of the Portfo-
lio computed as described above may tend to be higher than a like computation
made by a fund with identical investments utilizing a method of valuation
based upon market prices and estimates of market prices for all of its portfo-
lio instruments. Thus, if the use of amortized cost by the Portfolio resulted
in a lower aggregate portfolio value on a particular day, a prospective in-
vestor in the Portfolio would be able to obtain a somewhat higher yield than
would result from investment in a fund utilizing solely market values, and ex-
isting investors in the Portfolio would receive less investment income. The
converse would apply in a period of rising interest rates.
 
  The valuation of the New Jersey Money Market Portfolio's instruments based
upon their amortized cost and the commitment to maintain the Portfolio's per
share net asset value of $1.00 is permitted by Rule 2a-7 under the Investment
Company Act of 1940, pursuant to which the Fund has agreed to adhere to cer-
tain conditions. Accordingly, the Fund has agreed to maintain a dollar-
weighted average portfolio maturity for the New Jersey Money Market Portfolio
of 90 days or less, to purchase instruments having remaining maturities of one
year or less only, and to invest only in securities determined by the Board of
Trustees to be of good quality with minimal credit risks.
 
  It is a fundamental objective of management to maintain the Portfolio's
price per share as computed for the purpose of sales and redemptions at $1.00.
The Trustees have established procedures designed to achieve this objective.
Such procedures will include a review of the Portfolio's holdings by the
Trustees, at such intervals as they may deem appropriate, to determine whether
the Portfolio's net asset value calculated by using available market quota-
tions deviates from $1.00 per share based on amortized cost. The extent of any
deviation will be examined by the Trustees. If such deviation exceeds 1/2 of
1%, the Trustees will promptly consider what action, if any, will be initiat-
ed. In the event the Trustees determine that a deviation exists which may re-
sult in material dilution or other unfair results to investors or existing
shareholders, they have agreed to take such corrective action as they regard
as necessary and appropriate, including the sale of portfolio instruments
prior to maturity to realize capital gains or losses or to shorten average
portfolio maturity; withholding dividends; making a special capital distribu-
tion; redemptions of shares in kind; or establishing a net asset value per
share by using available market quotations.

THE VANGUARD GROUP
 
  Vanguard New Jersey Tax-Free Fund is a member of The Vanguard Group of In-
vestment 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 distribu-
tion services. Vanguard also provides investment advisory services on an at-
cost basis to several of the Vanguard Funds, including the Vanguard New Jersey
Tax-Free Fund.
 
                                                                           B-13
<PAGE>
 
  Vanguard employs a supporting staff of management and administrative person-
nel needed to provide the requisite services to the Funds and also furnishes
the Funds with necessary office space, furnishings and equipment. Each Fund
pays its share of Vanguard's net expenses which are allocated among the Funds
under methods approved by the Board of Trustees (Directors) of each Fund. In
addition, each Fund bears its own direct expenses such as legal, auditing and
custodian fees. In order to generate additional revenues for Vanguard and
thereby reduce the Fund's expenses, Vanguard also provides certain administra-
tive services to other organizations.
 
  The Fund's Officers are also Officers and employees of Vanguard. No Officer
or employee owns, or is permitted to own, any securities of any external ad-
viser 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 pre-
vent 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 per-
mitted to engage in personal securities transactions. However, such transac-
tions are subject to procedures and guidelines substantially similar to those
recommended by the mutual fund industry and approved by the U.S. Securities
and Exchange Commission.
 
  The Vanguard Group Inc. ("Vanguard") was established and operates under a
Fund's 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 No-
vember 30, 1994 Vanguard New Jersey Tax-Free Fund had contributed capital of
$223,000 to Vanguard representing 1.1% of Vanguard's capitalization. The
Fund's Service Agreement provides as follows: (a) each Vanguard Fund may in-
vest up to 0.40% of its current net assets in Vanguard and (b) there is no
other limitation on the amount that each Vanguard Fund may contribute to Van-
guard's capitalization.
 
  MANAGEMENT. Corporate management and administrative services include: (1)
executive staff; (2) accounting and financial; (3) legal and regulatory; (4)
shareholder account maintenance; (5) monitoring and control of custodian rela-
tionships; (6) shareholder reporting; and (7) review and evaluation of advi-
sory and other services provided to the Funds by third parties. During the
year ended November 30, 1994, the Fund's share of Vanguard's actual net costs
of operations relating to management and administrative services (including
transfer agency) totaled approximately $2,521,000.
 
  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 materi-
als and marketing personnel. Distribution services may also include organizing
and offering to the public, from time to time, one or more new investment com-
panies 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 or-
ganize 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 remain-
ing 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 na-
ture shall exceed 125% of the average
 
B-14
<PAGE>
 
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, 1994, the Fund paid approximately
$366,000 of the Group's distribution and marketing expenses.
 
  INVESTMENT ADVISORY SERVICES. Vanguard also provides investment advisory
services to the Fund, Vanguard Municipal Bond Fund, Vanguard Bond Index Fund,
Vanguard Money Market Reserves, Vanguard Institutional Money Market Portfolio,
Vanguard New York Insured Tax-Free Fund, Vanguard Ohio Tax-Free, Vanguard
Florida Insured Tax-Free Fund, Vanguard Pennsylvania Tax-Free Fund, Vanguard
California Tax-Free Fund, Vanguard Admiral Funds, Vanguard International Eq-
uity Index Fund, Vanguard Balanced Index Fund, Vanguard Institutional Index
Fund, Vanguard Index Trust, Vanguard Tax-Managed Fund, several Portfolios of
Vanguard Variable Insurance Fund, several Portfolios of Vanguard Fixed Income
Securities Fund, a portion of Vanguard/Windsor II, a portion of
Vanguard/Morgan Growth Fund as well as several indexed separate accounts.
These services are provided on an at-cost basis from a money management staff
employed directly by Vanguard. The compensation and other expenses of this
staff are paid by the Funds utilizing these services. During the years ended
November 30, 1992, 1993 and 1994 the Fund paid approximately $105,000,
$127,000 and $170,000 of Vanguard's investment advisory expenses.
   
  REMUNERATION OF TRUSTEES AND OFFICERS. The Fund pays each Trustee, who is
not also an Officer, an annual fee plus travel and other expenses incurred in
attending Board meetings. During the year ended November 30, 1994, the Fund
paid $6,000 in Trustee 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, 1994 the Fund's pro-
portionate share of remuneration paid to all Officers as a group was approxi-
mately $60,514.     
 
  Trustees who are not Officers are paid an annual fee based on the number of
years of service on the Board upon retirement. The fee is equal to $1,000 for
each year of service (up to fifteen years) and each investment company member
of the Vanguard Group contributes a proportionate amount to this fee based on
its relative net assets. Under its retirement plan, Vanguard contributes annu-
ally an amount equal to 10% of each eligible officer's annual compensation
plus 5.7% of that part of an eligible officer's compensation during the year,
if any, that exceeds the Social Security Taxable Wage Base then in effect. Un-
der its thrift plan, all eligible officers are permitted to make pre-tax con-
tributions in an amount up to 4% of total compensation, subject to federal tax
limitations, which are matched by Vanguard on a 100% basis. The Fund's propor-
tionate share of retirement contributions made by Vanguard under its retire-
ment and thrift plans on behalf of all Officers of the Fund, as a group, dur-
ing the 1994 fiscal year was approximately $6,633.
 
                                                                           B-15

                    DESCRIPTION OF SHARES AND VOTING RIGHTS
 
  The Fund was organized as a Pennsylvania Trust on September 25, 1987.
 
  The Declaration of Trust permits the Trustees to issue an unlimited number
of shares of beneficial interest, without par value, from an unlimited number
of separate classes ("Portfolios") of shares. Currently, the Fund is offering
shares of two Portfolios.
 
  The shares of the Fund are fully paid and nonassessable, except as set forth
under "Shareholder and Trustee Liability," and have no preference as to con-
version, 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 share-
holders, 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 out-
  standing, the Trustees may sell or convert the assets of the Fund to an-
  other 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 dis-
  tribute such assets ratably among the shareholders of the Fund; and
 
B-16
<PAGE>
 
  Upon completion of the distribution of the remaining proceeds or the remain-
ing 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 par-
ties 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 lia-
ble for errors of judgment or mistakes of fact or law, but nothing in the Dec-
laration of Trust protects a Trustee against any liability to which he would
otherwise be subject by reason of willful misfeasance, bad faith, gross negli-
gence, or reckless disregard of the duties involved in the conduct of his of-
fice.

         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 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 obliga-
tion" and "revenue" or "special tax" bonds. General obligation bonds are se-
cured 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 pay-
able only from the revenues derived from a particular facility or class of fa-
cilities 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), proj-
ect notes, demand notes and tax-exempt commercial papers (rated A-1 by Stan-
dard & 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
 
                                                                           B-17

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 mu-
nicipal obligations issued by states, cities, municipalities or municipal
agencies, include Tax Anticipation Notes, Revenue Anticipation Notes, Bond An-
ticipation Notes, Construction Loan Notes and Short-Term Discount Notes.
 
  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 ob-
ligations are secured by letters of credit or other credit support arrange-
ments provided by banks. The issuer of such notes normally has a corresponding
right, after a given period, to repay in its discretion the outstanding prin-
cipal 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 Bonds market, the size of a
particular offering, the maturity of the obligation, and the rating of the is-
sue. The ratings of Moody's Investors Service, Inc. and Standard and 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 ap-
praise 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 issu-
ance date can be a month or more. It is possible that the securities will
never be issued and the commitment canceled.
 
  From time to time proposals have been introduced before Congress to restrict
or eliminate the Federal income tax exemption for interest on Municipal Bonds.
Similar proposals may be introduced in the future. If any such 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 ex-
emption for interest on Municipal Bonds. Similar proposals may be introduced
in the future. If any such proposal were enacted, it might restrict or elimi-
nate the ability of each Portfolio to achieve its respective investment objec-
tive. In that event, the fund's trustees and officers would reevaluate its in-
vestment objective and policies and consider recommending to its shareholders
changes in such objective and policies. (For more information please refer to

  RATINGS. Excerpts from Moody's Investors Service, Inc.'s Municipal Bond
ratings: Aaa--judged to be of the "best quality" and are referred to as "gilt
edge"; interest payments are protected by a large or by an exceptionally
stable margin and principal is secure; Aa--judged to be of "high quality by
all standards" but as to which margins of protection or other elements make
long-term risks appear somewhat larger than Aaa-rated Municipal Bonds;
together with Aaa group they comprise what are generally known as "high grade
bonds"; A--possess many favorable investment attributes and are

considered "upper medium grade obligations." Factors giving security to
principal and interest of A-rated Municipal Bonds are considered adequate, but
elements may be present which suggest a susceptibility to impairment sometime
in the future; Baa--considered as medium grade obligations; i.e., they are
neither highly protected nor poorly secured; interest payments and principal
security appear adequate for the present but certain protective elements may
be lacking or may be characteristically unreliable over any great length of
time; Ba--protection of principal and interest payments may be very moderate;
judged to have speculative elements; their future cannot be considered as
well-assured; B--lack characteristics of a desirable investment; assurance of
interest and principal payments over any long period of time may be small;
Caa--poor standing; may be in default or there may be present elements of
danger with respect to principal and interest; Ca--speculative in a high
degree; often in default; C--lowest rated class of bonds; issues so rated can
be regarded as having extremely poor prospects for ever attaining any real
investment standing.
 
  Description of Moody's ratings of state and municipal notes: Moody's ratings
for state and municipal notes and other short-term obligations are designated
Moody's Investment Grade ("MIG"). Symbols used will be as follows: MIG-1--Best
quality, enjoying strong protection from established cash flows of funds for
their servicing or from established and broad-based access to the market for
refinancing, or both; MIG-2--High quality with margins of protection ample al-
though 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 prin-
cipal 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 condi-
tions 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 de-
fault, 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 is-
sues: SP-1+--very strong capacity to pay principal and interest; SP-1--strong
capacity to pay principal and interest.
 
  Description of S&P's highest commercial papers ratings: A-1+--This designa-
tion indicates the degree of safety regarding timely payment is overwhelming.
A-1--This designation indicates the degree of safety regarding timely payment
is very strong.

                    APPENDIX B--MUNICIPAL LEASE OBLIGATIONS
 
  Each Portfolio may invest in municipal lease obligations. Such securities
will be treated as liquid under the following guidelines have been established
by the Board of Trustees:
 
  1. The obligation has been rated "investment grade" by at least on 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 invest-
ors.
 
  4. The investment adviser has determined that the obligation, or a compara-
ble lessee security, trades in the institutional marketplace at least periodi-
cally, 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 obli-
gation 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 criti-
cal to the lessee"s ability to deliver essential services.
 
  7. Specific legal features such as covenants to maintain the tax-exempt sta-
tus 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 payment are net of property
maintenance, taxes and insurance).
 
  9. If the lessor is a private entity, there must be a sale and absolute as-
signment of rental payments to the trustee, accompanied by a legal opinion
from recognized bond counsel that lease payments would not be considered prop-
erty of the lessor's estate in the event of lessor's bankruptcy.
