WHY READING THIS PROSPECTUS IS IMPORTANT

This prospectus explains the objective, risks, and strategies of each Vanguard
Tax-Managed Fund. To highlight terms and concepts important to mutual fund
investors, we have provided "Plain Talk" explanations along the way. Reading the
prospectus will help you to decide which Funds, if any, are the right investment
for you. We suggest that you keep it for future reference.


IMPORTANT NOTE

Vanguard Tax-Managed Growth and Income Fund, Tax-Managed Capital Appreciation
Fund, and Tax-Managed Small-Cap Fund offer two separate classes of shares:
Investor and Institutional; Vanguard Tax-Managed Balanced Fund offers Investor
Shares only. This prospectus offers the Funds' Investor Shares, which have an
investment minimum of $10,000. The Funds' Institutional Shares, which have an
investment minimum of $10 million, are offered through a separate prospectus.
You can obtain a copy of the Institutional Shares prospectus by calling
Vanguard's Institutional Investor Services Department at 1-800-523-1036. Note
that the Funds' separate share classes have different expenses; as a result,
their investment performance will vary.

NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES
COMMISSION HAS APPROVED OR DISAPPROVED OF THESE SECURITIES OR PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.
<PAGE>   5
This prospectus provides information about Investor Shares of the four Vanguard
Tax-Managed Funds. Each of these funds is managed to minimize the impact of
taxes on investors' returns and uses an index-oriented approach to equity
investing. However, the funds differ considerably in their investment objectives
and strategies. Below you'll find profiles that summarize the key features of
each fund. Additional information concerning the funds, including an
Introduction to Tax-Efficient Investing, appears following the profiles.


FUND PROFILE -- TAX-MANAGED BALANCED FUND

INVESTMENT OBJECTIVE

Tax-Managed Balanced Fund seeks to provide a tax-efficient total return,
consisting of federally tax-exempt current income, a modest amount of taxable 
current income, and long-term capital growth.

INVESTMENT STRATEGIES

Tax-Managed Balanced Fund invests in a combination of municipal securities and
stocks. Approximately 50-55% of the Fund's assets will be invested in municipal
securities--bonds, notes, and other fixed income instruments issued by state and
local governments, that pay out federally tax-exempt income. The Fund emphasizes
high quality municipal securities; at least 75% of the Fund's bond holdings will
be rated in one of the top three credit rating categories as determined by an
independent bond rating agency. The dollar-weighted average maturity of the
Fund's municipal securities holdings will range from 7-12 years.

         Stocks chosen from the Russell 1000 Index--an independent index of the
stocks of large- and medium-size U.S. companies--will comprise the remaining
45-50% of the Fund's assets. Rather than purchasing all stocks within the
Russell 1000 Index, the Fund uses statistical methods to "sample" the Index. In
the aggregate, stocks selected by the Fund are expected to closely track the
investment performance of the Russell 1000 Index, while providing a lower
dividend yield than the Index.

PRIMARY RISKS

TAX-MANAGED BALANCED FUND'S TOTAL RETURN, LIKE STOCK PRICES GENERALLY, WILL
FLUCTUATE WITHIN A WIDE RANGE, SO AN INVESTOR COULD LOSE MONEY OVER SHORT OR
EVEN LONG PERIODS. The Fund is also subject to:

- -     Interest rate risk, which is the chance that bond prices overall,
      including the prices of bonds held by the Fund, will decline due to rising
      interest rates.

- -     Credit risk, which is the chance that a bond issuer--a state, local
      government or regional governmental authority--will fail to repay
      interest and principal in a timely manner. Credit risk, which has the
      potential to hurt the Fund's performance, should be low for the Fund.

- -     Investment style risk, which is the chance that returns from balanced
      funds will trail returns from funds with a different investment focus. 

PERFORMANCE/RISK INFORMATION

The bar chart and table below provide an indication of the risk of investing in
the Fund. The bar chart shows the Fund's performance in each calendar year since
inception. The table shows how the Fund's average annual returns for one
calendar year and since inception compare with those of a broad-based securities
market index. Keep in mind that the Fund's past performance does not indicate
how it will perform in the future.

FEES AND EXPENSES

The following table describes the fees and expenses you would pay if you buy and
hold Investor Shares of Tax-Managed Balanced Fund. The expenses shown under
Annual Fund Operating Expenses are based on estimated amounts for the current
fiscal year ended December 31, 1998.

SHAREHOLDER FEES (fees paid directly from your investment)

<TABLE>
<S>                                                                    <C>
Sales Charge (Load) Imposed on Purchases:                              None
Sales Charge (Load) Imposed on Reinvested Dividends:                   None 
Redemption Fees (includes redemptions by exchange to another fund):    2% or 1%* 
Exchange Fees:                                                         None 
</TABLE>

* A 2% redemption fee applies to shares held for less than 1 year; a 1%
redemption fee applies to shares held longer than 1 year but less than 5 years.
The fees are withheld from redemption proceeds and paid to the Fund. These fees
help to cover the transaction costs borne by the Fund when it must sell
securities to meet redemptions. In addition, these fees are intended to protect
the Fund's long-term investors from short-term traders, who erode the Fund's
tax-efficiency.

ANNUAL FUND OPERATING EXPENSES (expenses deducted from the Fund's assets)

<TABLE>
<S>                                                                    <C>
Management Expenses:                                                   -%

Other Expenses:                                                        -%
TOTAL OPERATING EXPENSES:                                              -%
</TABLE>

The following example is intended to help you compare the cost of investing in
the Fund with the cost of investing in other mutual funds. It illustrates the
hypothetical expenses that you would incur over various periods if you invested
$10,000 in the Fund's Investor Shares. This example assumes that the Fund
provides a return of 5% a year, that operating expenses remain the same, and
that you redeem all of your shares at the end of the given period. Although your
actual costs might be higher or lower, based on these assumptions your costs
would be:

<TABLE>
<CAPTION>
    1 YEAR           3 YEARS           5 YEARS           10 YEARS
    ------           -------           -------           --------

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

You would pay the following expenses if you did not redeem your shares (the
difference being that the Fund's 1% redemption fee would not apply to the
one-and three- year periods):

<TABLE>
<CAPTION>
    1 YEAR           3 YEARS           5 YEARS           10 YEARS

FUND PROFILE -- TAX-MANAGED GROWTH AND INCOME FUND

INVESTMENT OBJECTIVE

Tax-Managed Growth and Income Fund is a stock fund that seeks to provide a
tax-efficient total return, consisting of moderate current income and long-term
capital growth.

INVESTMENT STRATEGIES

Tax-Managed Growth and Income Fund purchases stocks included in the Standard &
Poor's 500 Composite Stock Price Index--an independent index that is dominated
by stocks of the largest U.S. companies. The Fund will hold substantially all of
the S&P 500 stocks, in approximately the same proportions as they are
represented in the Index.

PRIMARY RISKS

TAX-MANAGED GROWTH AND INCOME FUND'S TOTAL RETURN, LIKE STOCK PRICES GENERALLY,
WILL FLUCTUATE WITHIN A WIDE RANGE, SO AN INVESTOR COULD LOSE MONEY OVER SHORT
OR EVEN LONG PERIODS. The Fund is also subject to investment style risk, which
is the chance that returns from large-capitalization stocks--which are the types
of stocks that the Fund emphasizes--will trail returns from other asset classes
or the overall stock market.

FUND PROFILE -- TAX-MANAGED CAPITAL APPRECIATION FUND

INVESTMENT OBJECTIVE

Tax-Managed Capital Appreciation Fund is a stock fund that seeks to provide a
tax-efficient total return, consisting of long-term capital growth and nominal
current income.
<PAGE>   10
INVESTMENT STRATEGIES

Tax-Managed Capital Appreciation Fund purchases stocks included in the Russell
1000 Index--an independent index of the stocks of large- and medium-size U.S.
companies. Rather than purchasing all stocks within the Russell 1000 Index, the
Fund uses statistical methods to "sample" the Index. In the aggregate, stocks
selected by the Fund are expected to closely track the investment performance of
the Russell 1000 Index, while providing a lower dividend yield than that of the 
Index.

PRIMARY RISKS

TAX-MANAGED CAPITAL APPRECIATION FUND'S TOTAL RETURN, LIKE STOCK PRICES
GENERALLY, WILL FLUCTUATE WITHIN A WIDE RANGE, SO AN INVESTOR COULD LOSE MONEY
OVER SHORT OR EVEN LONG PERIODS. The Fund is also subject to investment style
risk, which is the chance that returns from large- and medium-capitalization
stocks--which are the types of stocks that the Fund emphasizes--will trail
returns from other asset classes or the overall stock market.

PERFORMANCE/RISK INFORMATION

The bar chart and table below provide an indication of the risk of investing in
Tax-Managed Capital Appreciation Fund. The bar chart shows the Fund's
performance in each calendar year since inception. The table shows how the
Fund's average annual returns for one calendar year and since inception compare
with those of a broad-based securities market index. Keep in mind that the
Fund's past performance does not indicate how it will perform in the future.

</TABLE>

* A 2% redemption fee applies to shares held for less than 1 year; a 1%
redemption fee applies to shares held longer than 1 year but less than 5 years.
The fees are withheld from redemption proceeds and paid to the Fund. These fees
help to cover the transaction costs borne by the Fund when it must sell
securities to meet redemptions. In addition, these fees are intended to protect
the Fund's long-term investors from short-term traders, who erode the Fund's
tax-efficiency.

FUND PROFILE -- VANGUARD TAX-MANAGED SMALL-CAP FUND

INVESTMENT OBJECTIVE

Tax-Managed Small-Cap Fund is a stock fund that seeks to provide a tax-efficient
total return, consisting of long-term capital growth and nominal current income.

INVESTMENT STRATEGIES

Tax-Managed Small-Cap Fund purchases stocks included in the Standard & Poor's
SmallCap 600 Index--an independent index that is made up of stocks of smaller
U.S. companies. The Fund will hold substantially all of the S&P SmallCap 600
stocks, in approximately the same proportions as they are represented in the
Index.

PRIMARY RISKS

TAX-MANAGED SMALL-CAP FUND'S TOTAL RETURN, LIKE STOCK PRICES GENERALLY, WILL
FLUCTUATE WITHIN A WIDE RANGE, SO AN INVESTOR COULD LOSE MONEY OVER SHORT OR
EVEN LONG PERIODS. The Fund is also subject to investment style risk, which is
the chance that returns from small- and medium-capitalization stocks--which are
the types of stocks that the Fund emphasizes--will trail returns from other
asset classes or the overall stock market. Small-capitalization stocks tend to
go through cycles of doing better--or worse--than the stock market in general.
These periods have, in the past, lasted for as long as several years.

PERFORMANCE/RISK INFORMATION
Tax-Managed Small-Cap Fund is new, so it has no performance information to
report yet.

FEES AND EXPENSES
The following table describes the fees and expenses you would pay if you buy and
hold Tax-Managed Small-Cap Fund-Investor Shares. The expenses shown under Annual
Fund Operating Expenses are based on estimated amounts for the current fiscal
year. The Fund has no operating history; actual operating expenses could be
different.

AN INTRODUCTION TO TAX-EFFICIENT INVESTING
<PAGE>   14
Most mutual funds seek to maximize PRE-TAX total returns, without regard to the
personal tax consequences incurred by investors. Yet, taxable investors stand to
lose a significant portion of their investment returns to federal, state and
local taxes. Fund dividends and short-term capital gains are now taxed at
federal income tax rates as high as 39.6%, and for long-term capital gains, the
rates reach up to 20%. The Vanguard Tax-Managed Funds aim to minimize the impact
of taxes on investors' total returns by operating in a tax-efficient manner.
The Funds use these tax-management techniques:

         LOW PORTFOLIO TURNOVER. The Funds minimize portfolio turnover by
employing an index-oriented approach to stock investing. Instead of trading
frequently, each Fund simply buys and holds the stocks comprising its target
index. Frequent trading--a hallmark of many actively-managed funds--causes funds
to realize capital gains, which must then be distributed to shareholders, 
reducing their after tax returns.

         A DISCIPLINED SELL-SELECTION METHOD. When selling specific securities,
the Funds will select a specific share lot-more often than not, the highest-cost
shares--in order to minimize realized capital gains. In addition, each Fund may
sell securities at a loss in order to offset realized capital gains that would
otherwise have to be distributed to shareholders.

         BIAS AGAINST TAXABLE DIVIDEND INCOME. The Tax-Managed Balanced and
Tax-Managed Capital Appreciation Funds minimize taxable dividend income by
focusing on the lower-yielding stocks within their shared, target index (the
Russell 1000 Index). In addition, the bond portion of Tax-Managed Balanced Fund
is comprised of municipal securities, which generate tax-exempt dividends.

         REDEMPTION FEES. Each Fund imposes redemption fees on short-term
investors, whose in-out activity can reduce a fund's tax efficiency by causing
it to realize capital gains. The fee is 2% for shares held for less than one
year, and 1% for shares held for more than one but less than five years. These
fees are paid to the Funds to help cover their transaction costs when selling
securities to meet redemptions.


A WORD ABOUT RISK

This prospectus describes the risks you would face as an investor in the
Vanguard Tax-Managed Funds. It is important to keep in mind one of the main
axioms of investing: The higher the potential reward, the higher the risk of
losing money. The reverse, also, is generally true: The lower the potential
reward, the lower the risk. As you consider an investment in one or more of the
Funds, you should also take into account your personal tolerance for the daily
fluctuations of the stock market.

  Look for this "warning flag" symbol [#] throughout the prospectus. It is used
to mark detailed information about each type of risk that you would confront as
a shareholder of one or more of the Funds.


PRIMARY INVESTMENT STRATEGIES

Each of the Funds follows a distinct set of investment strategies. This section
explains the strategies that the investment adviser uses in pursuit of each
Fund's objective. It also explains how the adviser implements these strategies.
In addition, this section discusses important risks faced by investors in the
Funds. The Funds' Board of Trustees oversees their management and may change the
investment strategies in the interest of shareholders.

MARKET EXPOSURE

The grid below shows, at a glance, the types of investments made by each Fund as
its primary investment strategy. In addition, the grid shows the percentage of
each Fund's assets that is normally committed to each listed type of investment.
Primary investment strategies are expected to play the most important role in
achieving a Fund's investment objective.

COMMON STOCKS. Each of the Funds invests in U.S. common stocks as a primary
investment strategy, although the size of the companies on which the Funds focus
varies.

  #EACH FUND IS SUBJECT TO MARKET RISK, WHICH IS THE POSSIBILITY THAT STOCK
PRICES OVERALL WILL DECLINE OVER SHORT OR EVEN LONG PERIODS. STOCK MARKETS TEND
TO MOVE IN CYCLES, WITH PERIODS OF RISING PRICES AND PERIODS OF FALLING PRICES.

  To illustrate the volatility of stock prices, the following table shows the
best, worst, and average total returns for the U.S. stock market over various
periods as measured by the Standard & Poor's 500 Composite Stock Price Index, a
widely used barometer of market activity. (Total returns consist of dividend
income plus change in market price.) Note that the returns shown do not include
the costs of buying and selling stocks or other expenses that a real-world
investment portfolio would incur. Note, also, that the gap between best and
worst tends to narrow over the long term.

                     U.S. STOCK MARKET RETURNS (1926 - 1997)

<TABLE>
<CAPTION>
                 1 YEAR     5 YEARS   10 YEARS   20 YEARS
<S>             <C>        <C>        <C>        <C>  
Best              53.9%      23.9%      20.1%      16.9%
Worst           - 43.3     - 12.5      - 0.9        3.1
Average           13.0       10.5       10.9       10.9
</TABLE>

  The table covers all of the 1-, 5-, 10-, and 20-year periods from 1926 through
1997. You can see, for example, that while the average return on stocks for all
of the 5-year periods was 10.5%, returns for individual 5-year periods ranged
from a - 12.5% average (from 1928 through 1932) to 23.9% (from 1951 through
1954). These average returns reflect past performance on common stocks; you
should not regard them as an indication of future returns from either the stock
market as a whole or these Funds in particular.

  Keep in mind that the S&P 500 Index--which is the index tracked by Tax-Managed
Growth and Income Fund -- holds mainly large-cap stocks. Historically, mid- and
small-cap stocks have been more volatile than -- and at times have performed
quite differently from -- large-cap stocks. This is due to several factors,
including less-certain growth and dividend prospects for smaller companies.
Tax-Managed Balanced and Tax-Managed Capital Appreciation Funds hold mid-cap
stocks in addition to large-cap stocks. On the other hand, Tax-Managed Small-Cap
Fund holds just small-cap stocks.

#THE FUNDS ARE SUBJECT, IN VARYING DEGREES, TO INVESTMENT STYLE RISK, WHICH IS
THE POSSIBILITY THAT RETURNS FROM A SPECIFIC TYPE OF STOCK (FOR INSTANCE, SMALL-
OR MID-CAP STOCKS) OR FUND WILL TRAIL RETURNS FROM OTHER ASSET CLASSES OR THE
OVERALL STOCK MARKET. EACH TYPE OF STOCK OR FUND TENDS TO GO THROUGH CYCLES OF
DOING BETTER -- OR WORSE -- THAN COMMON STOCKS IN GENERAL. THESE PERIODS HAVE,
IN THE PAST, LASTED FOR AS LONG AS SEVERAL YEARS.

                                PLAIN TALK ABOUT
                    LARGE-CAP, MID-CAP, AND SMALL-CAP STOCKS

Stocks of publicly traded companies -- and mutual funds that hold these stocks
- -- can be classified by the companies' market value, or capitalization.
Generally, Vanguard defines large-capitalization (large-cap) funds as those
holding stocks of companies whose outstanding shares have a median market value
exceeding $10 billion. Mid-cap funds hold stocks of companies with a median
market value between $1 billion and $10 billion. Small-cap funds typically hold
stocks of companies with a median market value of less than $1 billion.

MUNICIPAL SECURITIES. Tax-Managed Balanced Fund invests 50-55% of its assets in
municipal securities. Municipal securities are bonds, notes, and other fixed
income instruments issued by state and local governments and regional
governmental authorities. Municipal securities pay out federally tax-exempt
income. The Fund emphasizes high quality municipal securities; at least 75% of
the Fund's bond holdings will be rated in one of the top three credit rating
categories as determined by an independent bond rating agency. Up to 25% of the
Fund's bond holdings may be invested in bonds that have been rated in the fourth
highest rating category and, within that 25%, up to 5% may be invested in lower
rated securities or securities that are unrated. The dollar-weighted average
maturity of the Fund's municipal securities holdings will range from 7-12 years.

#DUE TO ITS BOND INVESTMENTS, TAX-MANAGED BALANCED FUND IS SUBJECT TO INTEREST
RATE RISK--THE CHANCE THAT BOND PRICES WILL FALL WHEN INTEREST RATES RISE--AND
CREDIT RISK--THE CHANCE THAT A BOND ISSUER WILL FAIL TO PAY INTEREST AND

                                 MUNICIPAL BONDS

Municipal bonds are securities issued by state and local governments and
regional governmental authorities as a way of raising money for public
construction projects (for example, highways, airports, or housing); for
operating expenses; or for loans to public institutions and facilities.

                            BONDS AND INTEREST RATES

As a rule, when interest rates rise, bond prices fall. The opposite is also
true: Bond prices go up when interest rates fall. Why do bond prices and
interest rates move in opposite directions? Let's assume that you hold a bond
offering a 5% yield. A year later, interest rates are on the rise and bonds are
offered with a 6% yield. With higher-yielding bonds available, you would have
trouble selling your 5% bond for the price you paid--causing you to lower your
asking price. On the other hand if interest rates were falling and 4% bonds were
being offered, you would be able to sell your 5% bond for more than you paid.

                                PLAIN TALK ABOUT
                                 BOND MATURITIES

A bond is issued with a specific maturity date--the date when the bond's issuer,
or seller, must pay back the bond's initial value (known as its "face value").
Bond maturities generally range from less than one year (short-term) to 30 years
(long-term). The longer a bond's maturity, the more risk you, as a bond
investor, face as interest rates rise--but also the more interest you could
receive. Long-term bonds are more suitable for investors willing to take greater
risks of price fluctuations to get higher interest income; short-term bond
investors should be willing to accept lower yields in return for less
fluctuation in the value of their investment.

                                PLAIN TALK ABOUT
                                 CREDIT QUALITY

A bond's credit quality depends on the issuer's ability to pay interest on the
bond and, ultimately, to repay the debt. Bonds issued or backed by the U.S.
Government offer maximum credit protection; bonds issued or backed by
financially troubled states or local governments can carry considerably more
risk. Municipal securities are usually rated by independent bond rating
agencies. The lower the rating by one of these rating agencies (for example,
Moody's or Standard & Poor's), the greater the chance (in the rating agency's
opinion) that the bond issuer will default, or fail to meet its payment
obligations. All things being equal, the lower a bond's credit rating, the
higher its yield should be to compensate investors for assuming additional risk.
Bonds rated in one of the four highest rating categories are considered
"investment grade."

SECURITY SELECTION

Each of the Funds employs an index-oriented approach to stock investing;
Tax-Managed Balanced Fund selects municipal securities based upon traditional,
active management techniques. The grid below shows, at a glance, the stock index
tracked by each Fund and the indexing method employed.

                                INDEXING METHODS

In seeking to track a particular index, funds generally use one of two methods
to select the stocks in which they invest. Some index funds hold each stock in
their target indexes in about the same proportions as represented in the indexes
themselves. This is called a REPLICATION METHOD. For example, if 5% of the S&P
500 Index were made up of the stock of a specific company, a fund tracking that
index (such as Tax-Managed Growth and Income Fund) would invest 5% of its assets
in that company. Other index funds may use a different security selection
process, a SAMPLING METHOD. Using a sophisticated computer program, these funds
select stocks that will mirror their target indexes in terms of industry
weightings, market capitalization, and other characteristics. For instance, if
10% of the Russell 1000 Index were made up of financial services stocks,
Tax-Managed Capital Appreciation Fund would invest about 10% of its assets in
the financial services stocks of the Index with overall similar characteristics.
Funds tend to use a sampling method when the target index includes too many
stocks to track cost-effectively.

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

OTHER INVESTMENT POLICIES AND RISKS

Each of the Funds may invest, to a limited extent, in futures contracts, options
(including puts and calls), warrants, convertible securities, and swap
agreements, which are all types of derivatives. Losses (or gains) involving
futures contracts can sometimes be substantial--in part because a relatively
small price movement in a futures contract may result in an immediate and
substantial loss (or gain) for a fund. Similar risks exist for warrants
(securities that permit their owners to purchase a specific number of shares of
stock at a predetermined price), convertible securities (securities that may be
exchanged for a different asset), and swap agreements (contracts between two
parties in which each agrees to make payments to the other based on the return
of a specified index or asset). For this reason, the Funds will not use futures,
options, warrants, convertible securities, or swap agreements for speculative
purposes or as leveraged investments that magnify the gains or losses of an
investment.

  Each of the Funds may invest in futures contracts and options so long as the
total value of these investments does not exceed 5% of the Fund's assets.

  The reasons for which a Fund will invest in futures and options are:

- - To keep cash on hand to meet shareholder redemptions or other needs while
simulating full investment in its benchmark index.

- - To reduce the Fund's transaction costs or add value when these instruments are
favorably priced.

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

                                PLAIN TALK ABOUT
                                   DERIVATIVES

A derivative is a financial contract whose value is based on (or "derived" from)
a traditional security (such as a stock or a bond), an asset (such as a
commodity like gold), or a market index (such as the S&P 500 Index). Futures and
options are derivatives that have been trading on regulated exchanges for more
than two decades. These "traditional" derivatives are standardized contracts
that can easily be bought and sold, and whose market values are determined and
published daily. It is these characteristics that differentiate futures and
options from the relatively new types of derivatives. If used for speculation or
as leveraged investments, derivatives can carry considerable risks.

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

  Each Fund may, from time to time, take temporary defensive measures--such as
holding cash reserves without limit--that are inconsistent with the Funds'
primary investment strategies, in response to adverse market, economic,
political, or other conditions. In taking such measures, a Fund may not achieve
its investment objective.

TURNOVER RATES
<PAGE>   18
Although the Funds generally seek to invest for the long term, each retains the
right to sell securities regardless of how long the securities have been held.
However, their index-oriented approach to stock investing and focus on avoiding
capital gains should hold the Funds' turnover rates for stocks fairly low, at
20% or less. (A turnover rate of 100% would occur, for example, if a Fund sold
and replaced securities valued at 100% of its net assets within a one-year
period.) Tax-Managed Balanced Fund's turnover rate for municipal securities is
expected to remain below 40%.

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

                                PLAIN TALK ABOUT
                                  TURNOVER RATE

Before investing in a mutual fund, you should review its turnover rate. This
gives an indication of how transaction costs could affect the fund's future
returns. In general, the greater the volume of buying and selling by the fund,
the greater the impact that brokerage commissions and other transaction costs
will have on its return. (These costs are in addition to those described in the
fee table which appears earlier in this prospectus.) Also, funds with high
turnover rates may be more likely to generate capital gains that must be
distributed to shareholders as income subject to taxes. The average turnover
rate for all domestic stock funds is approximately 80%.

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


COSTS AND MARKET-TIMING

  Some investors try to profit from market-timing -- switching money into
investments when they expect prices to rise, and taking money out when they
expect prices to fall. As money is shifted in and out, a fund incurs expenses
for buying and selling securities. These costs are borne by all fund
shareholders, including the long-term investors who do not generate the costs.
Therefore, the Tax-Managed Funds have adopted the following policies, among
others, designed to discourage short-term trading:

- -     The Funds reserve the right to reject any purchase request into any of the
      Funds -- including exchanges from other Vanguard funds -- that it regards
      as disruptive to the efficient management of the Funds. This could be
      because of the timing of the investment or because of a history of
      excessive trading by the investor.

- -     There is a limit on the number of times you can exchange into and out of a
      Fund (see "Redeeming Shares" in the INVESTING WITH VANGUARD section).

- -     The Funds impose a 2% redemption fee on shares that are redeemed by any
      method within one year of purchase. There is a 1% redemption fee on shares
      that are redeemed by any method more than one year but less than 5 years
      of purchase.

- -     The Funds reserve the right to stop offering shares at any time.

The Vanguard funds do not permit market-timing. Do not invest in these Funds if
you are a market-timer.


                                PLAIN TALK ABOUT
                            THE FUNDS' REDEMPTION FEE

The Tax-Managed Funds charge a redemption fee on shares that are redeemed,
including redeeming by exchange to another Vanguard fund, before they have been
held for five years. The fee is 2% for shares redeemed within one year of
purchase and 1% for shares redeemed after 1 year but within 5 years of purchase.
The Funds are intended for long-term investors, and this redemption fee ensures
that the costs associated with short-term trading are borne by the investors
making the transactions -- and not by those shareholders in the Funds for the
long term.

  At Vanguard, all fees are paid directly to the fund itself (unlike a sales
charge or load, which -- for many fund companies -- ends up in the pocket of the
sponsor, adviser, or sales representative).

                                PLAIN TALK ABOUT
                             THE COSTS OF INVESTING

Costs are an important consideration in choosing a mutual fund. That's because
you, as a shareholder, pay the costs of operating a fund, plus any transaction
costs associated with the fund's buying and selling of securities. These costs
can erode a substantial portion of the gross income or capital appreciation a
fund achieves. Even seemingly small differences in expenses can, over time, have
a dramatic impact on a fund's performance.

                                  FUND EXPENSES

All mutual funds have operating expenses. These expenses, which are deducted
from a fund's gross income, are expressed as a percentage of the net assets of
the fund. The Vanguard Tax-Managed Funds' expense ratios for Investor Shares in
fiscal year 1998 were as follows: Tax-Managed Balanced Fund -- X%, or $X per
$1,000 of average net assets; Tax-Managed Growth and Income Fund -- X%, or $X
per $1,000 of average net assets; and Tax-Managed Capital Appreciation Fund --
X%, or $X per $1,000 of average net assets. The expense ratio for Tax-Managed
Small-Cap Fund, which is new, is expected to be X%, or $X per $1,000 of average
net assets, for fiscal year 1999. The average equity mutual fund had expenses in
1997 of X%, or $X per $1,000 of average net assets, according to Lipper
Analytical Services, which reports on the mutual fund industry.


THE FUNDS AND VANGUARD

Vanguard Tax-Managed Funds are members of The Vanguard Group, a family of more
than 35 investment companies with more than 100 distinct investment portfolios
and total net assets of more than $390 billion. All of the Vanguard funds share
in the expenses associated with business operations, such as personnel, office
space, equipment, and advertising.

  Vanguard also provides marketing services to the funds. Although shareholders
do not pay sales commissions or 12b-1 distribution fees, each fund pays its
allocated share of The Vanguard Group's marketing costs.

                      VANGUARD'S UNIQUE CORPORATE STRUCTURE

The Vanguard Group is truly a MUTUAL mutual fund company. It is owned jointly by
the funds it oversees and thus indirectly by the shareholders in those funds.
Most other mutual funds are operated by for-profit management companies that may
be owned by one person, by a group of individuals, or by investors who own the
management company's stock. By contrast, Vanguard provides its services on an
"at-cost" basis, and the funds' expense ratios reflect only these costs. No
separate management company reaps profits or absorbs losses from operating the
funds.


INVESTMENT ADVISER

Each of the Tax-Managed Funds obtains advisory services on an at-cost basis from
The Vanguard Group, Valley Forge, Pennsylvania 19482. For the fiscal year ended
December 31, 1998, Tax-Managed Balanced Fund, Tax-Managed Growth and Income Fund
and Tax-Managed Capital Appreciation Fund paid advisory expenses of ________,
________, and ____________, which represented effective annual rates of ____,
____, and _____. Tax-Managed Small-Cap Fund began operations on February *,
1999, and advisory expenses for its first fiscal year are estimated at an
effective annual rate of ______.

The Funds have authorized the advisers to choose brokers or dealers to handle
the purchase and sale of securities for the Funds, and to get the best available
price and most favorable execution from these brokers with respect to all
transactions. Also, the Funds may direct the advisers to use a particular broker
for certain transactions in exchange for commission rebates or research services
provided to the Funds. However, the Group will not pay higher commissions
specifically for the purpose of obtaining research services.

YEAR 2000 CHALLENGE

The common practice in computer programming of using just two digits to identify
a year has resulted in the Year 2000 challenge throughout the information
technology industry. If unchanged, many computer applications and systems could
misinterpret dates occurring after December 31, 1999, leading to errors or
failure. Such failure could adversely affect a fund's operations, including
pricing, securities trading, and the servicing of shareholder accounts.

  The Vanguard Group is dedicated to providing uninterrupted, high-quality
performance from our computer systems before, during, and after 2000. In July
1998, we completed the renovation and initial testing of our internal systems.
Vanguard is diligently working with external partners, suppliers, and vendors,
including fund managers and other service providers, to assure that the systems
with which we interact remain operational at all times.

  In addition to taking every reasonable step to secure our internal systems and
external relationships, Vanguard is further developing contingency plans
intended to assure that unexpected systems failures will not adversely affect
the Funds' operations. Vanguard intends to monitor these processes through the
rollover of 1999 into 2000 and to quickly implement alternate solutions if
necessary.

  However, despite Vanguard's efforts and contingency plans, noncompliant
computer systems could have a material adverse effect on a Fund's business,
operations, or financial condition. Additionally, a Fund's performance could be
hurt if a computer-system failure at a company or governmental unit affects the
price of securities the Fund owns.



DIVIDENDS, CAPITAL GAINS, AND TAXES

Each December, the Tax-Managed Funds distribute to their shareholders virtually
all of their income from interest and dividends, as well as any capital gains
realized from the sale of its holdings. In addition, the Funds may occasionally
be required to make supplemental dividend or capital gains distributions at some
other time during the year.

  You can receive distributions of income or capital gains in cash, or you can
have them automatically invested in more shares of a Fund. In either case, these
distributions are taxable to you. It is important to note that distributions of
dividends and capital gains that are declared in December -- if paid to you by
the end of January -- are taxed as if they had been paid to you in December.

  Vanguard will send you a statement each year showing the tax status of all
your distributions. If you have chosen to receive dividend and/or capital gains
distributions in cash, and the postal or other delivery service is unable to
deliver checks to your address of record, we will change the distribution option
so that all dividends and other distributions are automatically invested in
additional shares. We will not pay interest on uncashed distribution checks.

- -     The dividends and short-term capital gains that you receive are considered
      ordinary income for tax purposes.

- -     Any distributions of net long-term capital gains by a Fund are taxable to
      you as long-term capital gains, no matter how long you've owned shares in
      the Fund.

- -     Although the Funds do not seek to realize any particular amount of capital
      gains during a year, such gains are realized from time to time as
      by-products of their ordinary investment activities. Consequently,
      distributions may vary considerably from year to year.

- -     If you sell or exchange shares, any gain or loss you have is a taxable
      event. This means that you may have a capital gain to report as income, or
      a capital loss to report as a deduction, when you complete your federal
      income tax return.

- -     Distributions of dividends or capital gains, and capital gains or losses
      from your sale or exchange of Fund shares, may be subject to state and
      local income taxes as well.

                                  DISTRIBUTIONS

As a shareholder, you are entitled to your share of the fund's income from
interest and dividends, and gains from the sale of investments. You receive such
earnings as either an income dividend or a capital gains distribution. Income
dividends come from both the dividends that the fund earns from its holdings and
the interest it receives from its money market and bond investments. Capital
gains are realized whenever the fund sells securities for higher prices than it
paid for them. The capital gains are either short-term or long-term depending on
whether the fund held the securities for less than or more than one year.



                                PLAIN TALK ABOUT
                               "BUYING A DIVIDEND"

Unless you are investing through a tax-deferred retirement account (such as an
IRA), it is not to your advantage to buy shares of a fund shortly before it
makes a distribution, because doing so can cost you money in taxes. This is
known as "buying a dividend." For example: on December 15, you invest $5,000,
buying 250 shares for $20 each. If the fund pays a distribution of $1 per share
on December 16, its share price would drop to $19 (not counting market change).
You still have only $5,000 (250 shares x $19 = $4,750 in share value, plus 250
shares x $1 = $250 in distributions), but you owe tax on the $250 distribution
you received -- even if you reinvest it in more shares. To avoid "buying a
dividend," check a fund's distribution schedule before you invest.


SHARE PRICE

Each Fund's share price, called its net asset value, or NAV, is calculated each
business day after the close of trading on the New York Stock Exchange (the NAV
is not calculated on holidays or other days the Exchange is closed). Net asset
value per share is computed by adding up the total value of the Fund's
investments and other assets, subtracting any of its liabilities (debts), and
then dividing by the number of Fund shares outstanding:

                            TOTAL ASSETS   -   LIABILITIES
   NET ASSET VALUE =     ---------------------------------------------
                             NUMBER OF SHARES OUTSTANDING

  Knowing the daily net asset value is useful to you as a shareholder because it
indicates the current value of your investment. The Fund's NAV, multiplied by
the number of shares you own, gives you the dollar amount you would have
received had you sold all of your shares back to the Fund that day.

  A NOTE ON PRICING: A Fund's investments will be priced at their market value
when market quotations are readily available. When these quotations are not
readily available, investments will be priced at their fair value, calculated
according to procedures adopted by the Board of Trustees.

  Each Fund's share price can be found daily in the mutual fund listings of most
major newspapers under the heading "Vanguard Funds." Different newspapers use
different abbreviations of the Funds' names, but the most common are TxMBal,
TxMGI, TxMCap, and ______ for Balanced, Growth and Income, Capital Appreciation,
and Small-Cap Fund, respectively.


                                PLAIN TALK ABOUT
                   HOW TO READ THE FINANCIAL HIGHLIGHTS TABLE

This explanation uses the Tax-Managed Balanced Fund as an example. The Fund
began fiscal 1998 with a net asset value (price) of $14.67 per share. During the
semi-annual period, the Fund earned $ - per share from investment income
(interest and dividends) and $ - per share from investments that had appreciated
in value or that were sold for higher prices than the Fund paid for them.

   Of those total earnings of $ - per share, $ - per share was returned to
shareholders in the form of dividend and capital gains distributions.
<PAGE>   22
   The earnings ($ - per share) minus the distributions ($ - per share) resulted
in a share price of $ - at the end of the year. This was an increase of $ - per
share (from $14.67 at the beginning of the year to $ - at the end of the year).
For a shareholder who reinvested the distributions in the purchase of more
shares, the total return from the Fund was - % for the year.

   As of December 31, 1998, the Fund had $ - billion in net assets; an expense
ratio of - % ($ - per $1,000 of net assets); and net investment income amounting
to - % of its average net assets. It sold and replaced securities valued at - %
of its total net assets.


FINANCIAL HIGHLIGHTS

The following financial highlights tables are intended to help you understand
each Fund's financial performance since its inception (except for Tax-Managed
Small-Cap Fund, which did not start until February *, 1999), and reflect
financial results for a single Fund share in each case. The total returns in
each table represent the BEFORE-TAX rate that an investor would have earned each
period on an investment in the Fund (assuming reinvestment of all dividends and
distributions, and complete redemption at the end of the period). Except for the
data relating the six-months ended June 30, 1998, this information has been
audited by PricewaterhouseCoopers LLP, independent accountants, whose report --
along with each Fund's financial statements -- is included in the Funds' most
recent annual report to shareholders. You may have the annual or semi-annual
report sent to you without charge by contacting Vanguard.

  From time to time, the Vanguard funds advertise yield and total return
figures. Yield is a measure of past dividend income. Total return includes both
past dividend income (assuming that it has been reinvested) plus realized and
unrealized capital appreciation (or depreciation). Neither yield nor total
return should be used to predict the future performance of a fund.

      You can redeem (that is, sell or exchange) shares purchased by check or
Vanguard Fund Express at any time. However, while your redemption request will
be processed at the next-determined net asset value after it is received, your
redemption proceeds will not be available until payment for your purchase is
collected, which may take up to ten calendar days.

      Keep in mind that if you buy or sell Fund shares through a registered
broker/dealer or investment adviser, the broker/dealer or adviser may charge you
a service fee.

- --------------------------------------------------------------------------------
A NOTE ON LARGE PURCHASES

It is important that you call Vanguard before you invest a large dollar amount.
We must consider the interests of all Fund shareholders and so reserve the right
to refuse any purchase that will disrupt the Fund's operation or performance.

- --------------------------------------------------------------------------------
REDEEMING SHARES

This section describes how you can redeem (that is, sell or exchange) the Funds'
shares.

      WHEN SELLING SHARES:

      - Vanguard sends the redemptions proceeds to you or a designated third
party. (Proceeds sent to third parties or different addresses require a
signature guarantee; see footnote on page ___.)

      - You can sell all or part of your Fund shares at any time.

      WHEN EXCHANGING SHARES:

      - The redemption proceeds are used to purchase shares of a different
Vanguard fund.

      - You must meet the receiving fund's minimum investment requirements.

      - Vanguard reserves the right to revise or terminate the exchange
privilege, limit the amount of an exchange, or reject an exchange at any time,
without notice.

In both cases, your transaction will be based on the Fund's next-determined
share price, subject to any special rules discussed in this prospectus. For
exchanges, the purchase side of the transaction will be based on the receiving
fund's next-determined share price, again subject to any special rules discussed
in this prospectus.

- --------------------------------------------------------------------------------
A NOTE ON REDEMPTION FEES

Each Fund imposes a 2% redemption fee on shares that are redeemed by any method
within one year of purchase. Each Fund imposes a 1% redemption fee on shares
that are redeemed by any method more than one year but less than 5 years from
purchase.

- --------------------------------------------------------------------------------
HOW TO REQUEST A REDEMPTION

You can request a redemption (that is, either a sale or exchange of shares) in
any one of three ways: Online, By Telephone, or By Mail.

ONLINE REQUESTS
ACCESS VANGUARD at www.vanguard.com

You can use your personal computer to sell or exchange shares of most Vanguard
funds by accessing our website. To establish this service, you must register
through the website. We will then send you, by mail, an account access password
that will enable you to sell or exchange shares online (as well as perform other
transactions).

      NOTE: The Vanguard funds whose shares you cannot exchange online or by
telephone are Vanguard U.S. Stock Index Funds, Vanguard Balanced Index Fund,
Vanguard International Stock Index Fund, Vanguard REIT Index 
<PAGE>   29
Fund, Vanguard Total International Stock Index Fund, and Vanguard Growth and
Income Fund. If you sell shares of these funds online, you will receive a
redemption check at your address of record.

TELEPHONE REQUESTS

Call Vanguard Tele-Account 24 hours a day--or Client Services during business
hours--to sell or exchange shares. You can exchange shares from this Fund to
open an account in another Vanguard fund or to add to an existing Vanguard fund
account with an identical registration.

      SPECIAL INFORMATION: We will automatically establish the telephone
redemption option for your account, unless your instruct us otherwise in
writing. While telephone redemption is easy and convenient, this account feature
involves a risk of loss from unauthorized or fraudulent transactions. Vanguard
will take reasonable precautions to protect your account from fraud. You should
do the same by keeping your account information private and immediately
reviewing any account statements that we send to you. Make sure to contact
Vanguard immediately about any transaction you believe to be unauthorized.

      We reserve the right to refuse a telephone redemption if the caller is
unable to provide:

      - The ten-digit account number.

      - The name and address exactly as registered on the account.

      - The primary Social Security or employer identification number as
        registered on the account.

      - The Personal Identification Number, if applicable.

      Please note that Vanguard will not be responsible for any account losses
due to telephone fraud, so long as we have taken reasonable steps to verify the
caller's identity. If you wish to remove the telephone redemption feature from
your account, please notify us in writing.

MAIL REQUESTS

Send a letter of instruction signed by all registered account holders. Include
the fund name and account number and (if you are selling) a dollar amount or
number of shares OR (if you are exchanging) the name of the fund you want to
exchange into and a dollar amount or number of shares. To exchange into an
account with a different registration (including a different name, address, or
taxpayer identification number), you must provide Vanguard with written
instructions that include the guaranteed signatures of all current account
owners.

OPTIONS FOR REDEMPTION PROCEEDS

You may receive your redemption proceeds in one of two ways: check or exchange
to another Vanguard fund.

      CHECK REDEMPTIONS. Normally, Vanguard will mail your check within two
business days of a redemption.

      EXCHANGE REDEMPTIONS. As described above, an exchange involves using the
proceeds of you redemption to purchase shares of another Vanguard fund.

FOR OUR MUTUAL PROTECTION

For your best interest and ours, Vanguard applies these additional requirements
to redemptions:

      REQUEST IN "GOOD ORDER." All redemption requests must be received by
Vanguard in "good order." This means that your request must include:

      - The Fund name and account number.

      - The amount of the transaction (in dollars or shares).

      - Signatures of all owners exactly as registered on the account (for mail
        requests).

      - Signature guarantees (if required). *

      - Any supporting legal documentation that may be required.

      - Any outstanding certificates representing shares to be redeemed.
<PAGE>   30
*For instance, a signature guarantee must be provided for all registered
shareholders when redemption proceeds are to be sent to a different person or
address. A signature guarantee can be obtained from most banks, credit unions,
and licensed brokers.

TRANSACTIONS ARE PROCESSED AT THE NEXT-DETERMINED SHARE PRICE AFTER VANGUARD HAS
RECEIVED ALL REQUIRED INFORMATION.

      LIMITS ON ACCOUNT ACTIVITY. "Because excessive account transactions can
disrupt management of the Fund and increase the Fund's costs for all
shareholders, Vanguard limits account activity as follows:

      - You may make no more than TWO SUBSTANTIVE "ROUND TRIPS" THROUGH THE FUND
      during any 12-month period.

      - Your round trips through the Fund must be at least 30-days apart.

      - The Fund may refuse a share purchase at any time, for any reason.

      - Vanguard may revoke an investor's telephone exchange privilege at any
      time, for any reason.

A "round trip" is a redemption from the Fund followed by a purchase back into
the Fund. Also, "round trip" covers transactions accomplished by any combination
methods, including transactions conducted by check, wire, or exchange to/from
another Vanguard fund. "Substantive" means a dollar amount that Vanguard
determines, in its sole discretion, could adversely affect management of the
Fund."

      RETURN YOUR SHARE CERTIFICATES. Any portion of your account represented by
share certificates cannot be redeemed until you return the certificates to
Vanguard.

      ALL TRADES FINAL. Vanguard will not cancel any transaction request
(including any purchase or redemption) that we believe to be authentic once the
request has been received and a confirmation number assigned.

A NOTE ON UNUSUAL CIRCUMSTANCES

Vanguard reserves the right to revise or terminate the telephone redemption
privilege at any time, without notice. In addition, Vanguard can stop selling
shares or postpone payment at times when the New York Stock Exchange is closed
or under any emergency circumstances as determined by the U.S. Securities and
Exchange Commission. 

      If you experience difficulty making a telephone redemption during periods
of drastic economic or market change, you can send us your request by regular or
express mail. Follow the instructions on selling or exchanging shares by mail in
this section.
- --------------------------------------------------------------------------------
- --------------------------------------------------------------------------------
A NOTE ON LARGE REDEMPTIONS

It is important that you call Vanguard before you redeem a large dollar amount.
We must consider the interests of all Fund shareholders and so reserve the right
to delay delivery of your redemption proceeds -- up to seven days -- if the
amount will disrupt the Fund's operation or performance.

      If you redeem more than $250,000 worth of Fund shares within any 90-day
period, the Fund reserves the right to pay part or all of the redemption
proceeds above $250,000 in kind, i.e., in securities, rather than in cash. If
payment is made in kind, you may incur brokerage commissions if you elect to
sell the securities for cash.
- --------------------------------------------------------------------------------
TRANSFERRING REGISTRATION

You can transfer the registration of your Fund shares to another owner by
completing a transfer form and sending it to Vanguard.

FUND AND ACCOUNT UPDATES

STATEMENTS AND REPORTS

We will send you clear, concise account and tax statements to help you keep
track of your Fund account throughout the year as well as when you are preparing
your income tax returns.

      In addition, you will receive financial reports about the Fund twice a
year. These comprehensive reports include an assessment of the Fund's
performance (and a comparison to its industry benchmark), an overview of the
markets, a report from the advisers, a listing of the Fund's holdings, and other
financial statements.

      To keep the Fund's costs as low as possible (so that you and other
shareholders can keep more of the Fund's investment earnings), Vanguard attempts
to eliminate duplicate mailings to the same address. When we find that two or
more Fund shareholders have the same last name and address, we send just one
Fund report to that address -- instead of mailing separate reports to each
shareholder. If you want us to send separate reports, however, you may notify
our Investor Information Department at 1-800-662-7447.

                          GLOSSARY OF INVESTMENT TERMS

CAPITAL GAINS DISTRIBUTION

Payment to mutual fund shareholders of gains realized on securities that the
fund has sold at a profit, minus any realized losses.

CASH RESERVES

Cash deposits, short-term bank deposits, and money market instruments which 
include U.S. Treasury bills, bank certificates of deposit (CDs), repurchase 
agreements, commercial paper, and banker's acceptances.

COMMON STOCK

A security representing ownership rights in a corporation. A stockholder is 
entitled to share in the company's profits, some of which may be paid out as 
dividends.

DIVIDEND INCOME

Payment to shareholders of income from interest or dividends generated by a 
fund's investments.

DOLLAR-COST AVERAGING

Investing equal amounts of money at regular intervals on an ongoing basis. This 
technique ensures that an investor buys fewer shares when prices are high and

EXPENSE RATIO

The percentage of a fund's average net assets used to pay its expenses. The 
expense ratio includes management fees, administrative fees, and any 12b-1 
distribution fees.

FIXED-INCOME SECURITIES

Investments, such as bonds, that have a fixed payment schedule. While the level 
of income offered by these securities is predetermined, their prices may 
fluctuate.

FUND DIVERSIFICATION

Holding a variety of securities so that a fund's return is not badly hurt by 
the poor performance of a single security or industry.

GROWTH STOCK FUND

A mutual fund that emphasizes stocks of companies believed to have above-average
prospects for growth. Reflecting market expectations for superior growth, the
prices of growth stocks often are relatively high in comparison to revenue,
earnings, book value and dividends.

INVESTMENT ADVISER

An organization that makes the day-to-day decisions regarding a fund's 
investments.

NET ASSET VALUE (NAV)

from the past year. A stock selling for $20, with earnings of $2 per share, has

SECURITIES

Stocks, bonds, and other investment vehicles.

TOTAL RETURN

A percentage change, over a specified time period, in a mutual fund's net asset 
value, with the ending net asset value adjusted to account for the reinvestment 
of all distributions of dividends and capital gains.

VALUE STOCK FUND
A mutual fund that emphasizes stocks of companies whose growth prospects are 
generally regarded as subpar by the market. Reflecting these market 
expectations, the prices of value stocks typically are below-average in 
comparison to such factors as revenue, earnings, book value, and dividends.

VOLATILITY

The fluctuations in value of a mutual fund or other security. The greater a 
fund's volatility, the wider the fluctuations between its high and low prices.

WHY READING THIS PROSPECTUS IS IMPORTANT
This prospectus explains the objective, risks, and strategies of each Vanguard
Tax-Managed Fund. To highlight terms and concepts important to mutual fund
investors, we have provided "Plain Talk" explanations along the way. Reading the
prospectus will help you to decide which Funds, if any, are the right investment
for you. We suggest that you keep it for future reference.


IMPORTANT NOTE
Vanguard Tax-Managed Growth and Income Fund, Tax-Managed Capital Appreciation
Fund, and Tax-Managed Small-Cap Fund offer two separate classes of shares:
Investor and Institutional; Vanguard Tax-Managed Balanced Fund offers Investor 
Shares only. This prospectus offers the Funds' Institutional Shares, which have
an investment minimum of $10 million. The Funds' Investor Shares, which have an
investment minimum of $10,000, are offered through a separate prospectus. You
can obtain a copy of the Investor Shares prospectus by calling Vanguard's
Investor Information Department at 1-800-662-7447. Note that the Funds' separate
share classes have different expenses; as a result, their investment performance
will vary.

NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES
COMMISSION HAS APPROVED OR DISAPPROVED OF THESE SECURITIES OR PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.

This prospectus provides information about Institutional Shares of three
Vanguard Tax-Managed Funds. Each of these funds is managed to minimize the
impact of taxes on investors' returns and uses an index-oriented approach to
equity investing. However, the funds differ considerably in their investment
objectives and strategies. Below you'll find profiles that summarize the key
features of each fund. Additional information concerning the funds, including an
Introduction to Tax-Efficient Investing, appears following the profiles.

FUND PROFILE -- TAX-MANAGED GROWTH AND INCOME FUND

INVESTMENT OBJECTIVE

Tax-Managed Growth and Income Fund is a stock fund that seeks to provide a
tax-efficient total return, consisting of moderate current income and long-term
capital growth.

INVESTMENT STRATEGIES

Tax-Managed Growth and Income Fund purchases stocks included in the Standard &
Poor's 500 Composite Stock Price Index--an independent index that is dominated
by stocks of the largest U.S. companies. The Fund will hold substantially all of
the S&P 500 stocks, in approximately the same proportions as they are
represented in the Index.

PRIMARY RISKS

TAX-MANAGED GROWTH AND INCOME FUND'S TOTAL RETURN, LIKE STOCK PRICES GENERALLY,
WILL FLUCTUATE WITHIN A WIDE RANGE, SO AN INVESTOR COULD LOSE MONEY OVER SHORT
OR EVEN LONG PERIODS. The Fund is also subject to investment style risk, which
is the chance that returns from large-capitalization stocks--which are the
types of stocks that the Fund emphasizes--will trail returns from other asset
classes or the overall stock market.

PERFORMANCE/RISK INFORMATION

The bar chart and table below provide an indication of the risk of investing in
Tax-Managed Growth and Income Fund. The bar chart shows the Fund's performance
in each calendar year since inception. The table shows how the Fund's average
annual returns for one calendar year and since inception compare with those of a
broad-based securities market index. Keep in mind that the Fund's past
performance does not indicate how it will perform in the future.

Note: This prospectus offers the Fund's Institutional Shares not the Investor
Shares. Performance for the Investor Shares is shown here because the Fund's
Institutional Shares are new. However, the two share classes are invested in the
same portfolio of securities and will have the same annual returns except to the
extent that their operating expenses differ.


                    ANNUAL TOTAL RETURNS FOR INVESTOR SHARES

During the period shown in the bar chart, the highest return for a calendar
quarter was -% (quarter ending _____________ ) and the lowest return for a
quarter was - -% (quarter ending _____________ ).

FUND PROFILE -- TAX-MANAGED CAPITAL APPRECIATION FUND
<PAGE>   40
INVESTMENT OBJECTIVE

Tax-Managed Capital Appreciation Fund is a stock fund that seeks to provide a
tax-efficient total return, consisting of long-term capital growth and nominal
current income.

INVESTMENT STRATEGIES

Tax-Managed Capital Appreciation Fund purchases stocks included in the Russell
1000 Index--an independent index of the stocks of large- and medium-size U.S.
companies. Rather than purchasing all stocks within the Russell 1000 Index, the
Fund uses statistical methods to "sample" the Index. In the aggregate, stocks
selected by the Fund are expected to closely track the investment performance of
the Russell 1000 Index, while providing a lower dividend yield than that of the 
index.

PRIMARY RISKS

TAX-MANAGED CAPITAL APPRECIATION FUND'S TOTAL RETURN, LIKE STOCK PRICES
GENERALLY, WILL FLUCTUATE WITHIN A WIDE RANGE, SO AN INVESTOR COULD LOSE MONEY
OVER SHORT OR EVEN LONG PERIODS. The Fund is also subject to investment style
risk, which is the chance that returns from large- and medium-capitalization
stocks--which are the types of stocks that the Fund emphasizes--will trail
returns from other asset classes or the overall stock market.

FUND PROFILE -- VANGUARD TAX-MANAGED SMALL-CAP FUND

INVESTMENT OBJECTIVE

Tax-Managed Small-Cap Fund is a stock fund that seeks to provide a tax-efficient
total return, consisting of long-term capital growth and nominal current income.

INVESTMENT STRATEGIES

Tax-Managed Small-Cap Fund purchases stocks included in the Standard & Poor's
SmallCap 600 Index--an independent index that is made up of stocks of smaller
U.S. companies. The Fund will hold substantially all of the S&P SmallCap 600
stocks, in approximately the same proportions as they are represented in the
Index.

PRIMARY RISKS

TAX-MANAGED SMALL-CAP FUND'S TOTAL RETURN, LIKE STOCK PRICES GENERALLY, WILL
FLUCTUATE WITHIN A WIDE RANGE, SO AN INVESTOR COULD LOSE MONEY OVER SHORT OR
EVEN LONG PERIODS. The Fund is also subject to investment style risk, which is
the chance that returns from small- and medium- capitalization stocks --which
are the types of stocks that the Fund emphasizes--will trail returns from other
asset classes or the overall stock market. Small-capitalization stocks tend to
go through cycles of doing better--or worse--than the stock market in general.
These periods have, in the past, lasted for as long as several years.

PERFORMANCE/RISK INFORMATION

Tax-Managed Small-Cap Fund is new, so it has no performance information to
report yet.

FEES AND EXPENSES

The following table describes the fees and expenses you would pay if you buy and
hold Tax-Managed Small-Cap Fund-Institutional Shares. The expenses shown under
Annual Fund Operating Expenses are based on estimated amounts for the current
fiscal year. The Fund has no operating history; actual operating expenses could

AN INTRODUCTION TO TAX-EFFICIENT INVESTING
<PAGE>   44
Most mutual funds seek to maximize PRE-TAX total returns, without regard to the
personal tax consequences incurred by investors. Yet, taxable investors stand to
lose a significant portion of their investment returns to federal, state and
local taxes. Fund dividends and short-term capital gains are now taxed at
federal income tax rates as high as 39.6%, and for long-term capital gains, the
rates reach up to 20%. The Vanguard Tax-Managed Funds aim to minimize the impact
of taxes on investors' total returns by operating in a tax-efficient manner. The
Funds use these tax-management techniques:

      LOW PORTFOLIO TURNOVER. The Funds minimize portfolio turnover by employing
an index-oriented approach to stock investing. Instead of trading frequently,
each Fund simply buys and holds the stocks comprising its target index. Frequent
trading--a hallmark of many actively-managed funds--causes funds to realize
capital gains, which must then be distributed to shareholders, reducing their 
after-tax returns.

     A DISCIPLINED SELL-SELECTION METHOD. When selling specific securities, the
Funds will select a specific share lot - more often than not, the highest-cost
shares - in order to minimize realized capital gains. In addition, each Fund
may sell securities at a loss in order to offset realized capital gains that
would otherwise have to be distributed to shareholders.

     BIAS AGAINST TAXABLE DIVIDEND INCOME. The Tax-Managed Capital Appreciation
Fund minimizes taxable dividend income by focusing on the lower-yielding stocks
within its target index (the Russell 1000 Index).

      REDEMPTION FEES. Each Fund imposes redemption fees on short-term
investors, whose in-out activity can reduce a fund's tax efficiency by causing
it to realize capital gains. The fee is 2% for shares held for less than one
year, and 1% for shares held for more than one but less than five years. These
fees are paid to the Funds to help cover their transaction costs when selling
securities to meet redemptions.


A WORD ABOUT RISK

This prospectus describes the risks you would face as an investor in the
Vanguard Tax-Managed Funds. It is important to keep in mind one of the main
axioms of investing: The higher the potential reward, the higher the risk of
losing money. The reverse, also, is generally true: The lower the potential
reward, the lower the risk. As you consider an investment in one or more of the
Funds, you should also take into account your personal tolerance for the daily
fluctuations of the stock market.

Look for this "warning flag" symbol [#] throughout the prospectus. It is used to
mark detailed information about each type of risk that you would confront as a
shareholder of one or more of the Funds.


PRIMARY INVESTMENT STRATEGIES

Each of the Funds follows a distinct set of investment strategies. This section

#EACH FUND IS SUBJECT TO MARKET RISK, WHICH IS THE POSSIBILITY THAT STOCK PRICES
OVERALL WILL DECLINE OVER SHORT OR EVEN LONG PERIODS. STOCK MARKETS TEND TO MOVE
IN CYCLES, WITH PERIODS OF RISING PRICES AND PERIODS OF FALLING PRICES.

 To illustrate the volatility of stock prices, the following table shows the
best, worst, and average total returns for the U.S. stock market over various
periods as measured by the Standard & Poor's 500 Composite Stock Price Index, a
widely used barometer of market activity. (Total returns consist of dividend
income plus change in market price.) Note that the returns shown do not include
the costs of buying and selling stocks or other expenses that a real-world
investment portfolio would incur. Note, also, that the gap between best and
worst tends to narrow over the long term.

</TABLE>

The table covers all of the 1-, 5-, 10-, and 20-year periods from 1926 through
1997. You can see, for example, that while the average return on stocks for all
of the 5-year periods was 10.5%, returns for individual 5-year periods ranged
from a - 12.5% average (from 1928 through 1932) to 23.9% (from 1951 through
1954). These average returns reflect past performance on common stocks; you
should not regard them as an indication of future returns from either the stock
market as a whole or these Funds in particular.

Keep in mind that the S&P 500 Index--which is the index tracked by Tax-Managed
Growth and Income Fund -- holds mainly large-cap stocks. Historically, mid- and
small-cap stocks have been more volatile than -- and at times have performed
quite differently from -- large-cap stocks. This is due to several factors,
including less-certain growth and dividend prospects for smaller companies.
Tax-Managed Capital Appreciation Fund holds mid-cap stocks in addition to 
large-cap stocks. On the other hand, Tax-Managed Small-Cap Fund holds just 
small-cap stocks.

#THE FUNDS ARE SUBJECT, IN VARYING DEGREES, TO INVESTMENT STYLE RISK, WHICH IS
THE POSSIBILITY THAT RETURNS FROM A SPECIFIC TYPE OF STOCK (FOR INSTANCE, SMALL-
OR MID-CAP STOCKS) OR FUND WILL TRAIL RETURNS FROM OTHER ASSET CLASSES OR THE
OVERALL STOCK MARKET. EACH TYPE OF STOCK OR FUND TENDS TO GO THROUGH CYCLES OF
DOING BETTER -- OR WORSE -- THAN COMMON STOCKS IN GENERAL. THESE PERIODS HAVE,
IN THE PAST, LASTED FOR AS LONG AS SEVERAL YEARS.

                   LARGE-CAP, MID-CAP, AND SMALL-CAP STOCKS

Stocks of publicly traded companies -- and mutual funds that hold these stocks
- -- can be classified by the companies' market value, or capitalization.
Generally, Vanguard defines large-capitalization (large-cap) funds as those
holding stocks of companies whose outstanding shares have a median market value
exceeding $10 billion. Mid-cap funds hold stocks of companies with a median
market value between $1 billion and $10 billion. Small-cap funds typically hold
stocks of companies with a median market value of less than $1 billion.

                               INDEXING METHODS

In seeking to track a particular index, funds generally use one of two methods
to select the stocks in which they invest. Some index funds hold each stock in
their target indexes in about the same proportions as represented in the indexes
themselves.  This is called a REPLICATION METHOD.  For example, if 5% of the S&P
500 Index were made up of the stock of a specific company, a fund tracking that
index (such as Tax-Managed Growth and Income Fund) would invest 5% of its assets
in that company. Other index funds may use a different security selection
process, a SAMPLING METHOD. Using a sophisticated computer program, these funds
select stocks that will mirror their target indexes in terms of industry
weightings, market capitalization, and other characteristics. For instance, if
10% of the Russell 1000 Index were made up of financial services stocks,
Tax-Managed Capital Appreciation Fund would invest about 10% of its assets in
the financial services stocks of the Index with overall similar characteristics.
Funds tend to use a sampling method when the target index includes too many
stocks to track cost-effectively.

OTHER INVESTMENT POLICIES AND RISKS

Each of the Funds may invest, to a limited extent, in futures contracts, options
(including puts and calls), warrants, convertible securities, and swap
agreements, which are all types of derivatives. Losses (or gains) involving
futures contracts can sometimes be substantial -- in part because a relatively
small price movement in a futures contract may result in an immediate and
substantial loss (or gain) for a fund. Similar risks exist for warrants
(securities that permit their owners to purchase a specific number of shares of
stock at a predetermined price), convertible securities (securities that may be
exchanged for a different asset), and swap agreements (contracts between two
parties in which each agrees to make payments to the other based on the return
of a specified index or asset). For this reason, the Funds will not use futures,
options, warrants, convertible securities, or swap agreements for speculative
purposes or as leveraged investments that magnify the gains or losses of an
investment.

Each of the Funds may invest in futures contracts and options so long as the
total value of these investments does not exceed 5% of the Fund's assets.

The reasons for which a Fund will invest in futures and options are:

- -        To keep cash on hand to meet shareholder redemptions or other needs
         while simulating full investment in stocks.

- -        To reduce the Fund's transaction costs or add value when these
         instruments are favorably priced.

                               PLAIN TALK ABOUT

                                 DERIVATIVES

A derivative is a financial contract whose value is based on (or "derived"
from) a traditional security (such as a stock), an asset (such as a commodity
like gold), or a market index (such as the S&P 500 Index). Futures and options
are derivatives that have been trading on regulated exchanges for more than two
decades. These "traditional" derivatives are standardized contracts that can
easily be bought and sold, and whose market values are determined and published
daily. It is these characteristics that differentiate futures and options from
the relatively new types of derivatives. If used for speculation or as leveraged
investments, derivatives can carry considerable risks.

  Each Fund may, from time to time, take temporary defensive measures--such as
holding cash reserves without limit--that are inconsistent with the Funds'
primary investment strategies, in response to adverse market, economic,
political, or other conditions. In taking such measures, a Fund may not achieve
its investment objective.

TURNOVER RATES
<PAGE>   48
Although the Funds generally seek to invest for the long term, each retains the
right to sell securities regardless of how long the securities have been held.
However, their index-oriented approach to stock investing and focus on avoiding
capital gains should hold the Funds' turnover rates for stocks fairly low, at
20% or less. (A turnover rate of 100% would occur, for example, if a Fund sold
and replaced securities valued at 100% of its net assets within a one-year
period.)

                               PLAIN TALK ABOUT

                                TURNOVER RATE

Before investing in a mutual fund, you should review its turnover rate. This
gives an indication of how transaction costs could affect the fund's future
returns. In general, the greater the volume of buying and selling by the fund,
the greater the impact that brokerage commissions and other transaction costs
will have on its return. (These costs are in addition to those described in the
fee table which appears earlier in this prospectus.) Also, funds with high
turnover rates may be more likely to generate capital gains that must be
distributed to shareholders as income subject to taxes. The average turnover
rate for all domestic stock funds is approximately 80%.


COSTS AND MARKET-TIMING

 Some investors try to profit from market-timing -- switching money into
investments when they expect prices to rise, and taking money out when they
expect prices to fall. As money is shifted in and out, a fund incurs expenses
for buying and selling securities. These costs are borne by all fund
shareholders, including the long-term investors who do not generate the costs.
Therefore, the Tax-Managed Funds have adopted the following policies, among
others, designed to discourage short-term trading:

- -        The Funds reserve the right to reject any purchase request into any of
         the Funds -- including exchanges from other Vanguard funds -- that it
         regards as disruptive to the efficient management of the Funds. This
         could be because of the timing of the investment or because of a
         history of excessive trading by the investor.

- -        There is a limit on the number of times you can exchange into and out
         of a Fund (see "Redeeming Shares" in the INVESTING WITH VANGUARD
         section).

- -        The Funds impose a 2% redemption fee on shares that are redeemed by any
         method within one year of purchase. There is a 1% redemption fee on
         shares that are redeemed by any method more than one year but less than
         5 years of purchase.

- -        The Funds reserve the right to stop offering shares at any time.

The Vanguard funds do not permit market-timing. Do not invest in these Funds if
you are a market-timer.

                         THE FUNDS' REDEMPTION FEE

The Tax-Managed Funds charge a redemption fee on shares that are redeemed,
including redeeming by exchange to another Vanguard fund, before they have been
held for five years. The fee is 2% for shares redeemed within 1 year of purchase
and 1% for shares redeemed after 1 year but within 5 years of purchase. The
Funds are intended for long-term investors, and this redemption fee ensures that
the costs associated with short-term trading are borne by the investors making
the transactions -- and not by those shareholders in the Funds for the long
term. At Vanguard, all fees are paid directly to the fund itself (unlike a sales
charge or load, which -- for many fund companies -- ends up in the pocket of the
sponsor, adviser, or sales representative).

                            THE COSTS OF INVESTING

Costs are an important consideration in choosing a mutual fund. That's because
you, as a shareholder, pay the costs of operating a fund, plus any transaction
costs associated with the fund's buying and selling of securities. These costs
can erode a substantial portion of the gross income or capital appreciation a
fund achieves. Even seemingly small differences in expenses can, over time, have
a dramatic effect on a fund's performance.

                                FUND EXPENSES

All mutual funds have operating expenses. These expenses, which are deducted
from a fund's gross income, are expressed as a percentage of the net assets of
the fund. The Vanguard Tax-Managed Funds' expense ratios for Investor Shares in
fiscal year 1998 were as follows: Tax-Managed Growth and Income Fund -- X%, or
$X per $1,000 of average net assets; and Tax-Managed Capital Appreciation Fund
- -- X%, or $X per $1,000 of average net assets. The expense ratio for Tax-Managed
Small-Cap Fund, which is new, is expected to be X%, or $X per $1,000 of average
net assets, for fiscal year 1999. The average equity mutual fund had expenses in
1997 of X%, or $X per $1,000 of average net assets, according to Lipper
Analytical Services, which reports on the mutual fund industry.


THE FUNDS AND VANGUARD

Vanguard Tax-Managed Funds are members of The Vanguard Group, a family of more
than 35 investment companies with more than 100 distinct investment portfolios
and total net assets of more than $390 billion. All of the Vanguard funds share
in the expenses associated with business operations, such as personnel, office
space, equipment, and advertising.

Vanguard also provides marketing services to the funds. Although shareholders
do not pay sales commissions or 12b-1 distribution fees, each fund pays its
allocated share of The Vanguard Group's marketing costs.

                      VANGUARD'S UNIQUE CORPORATE STRUCTURE

The Vanguard Group is truly a MUTUAL mutual fund company. It is owned jointly by
the funds it oversees and thus indirectly by the shareholders in those funds.
Most other mutual funds are operated by for-profit management companies that may
be owned by one person, by a group of individuals, or by investors who own the
management company's stock. By contrast, Vanguard provides its services on an
"at-cost" basis, and the funds' expense ratios reflect only these costs. No
separate management company reaps profits or absorbs losses from operating the
funds.


INVESTMENT ADVISER

Each of the Tax-Managed Funds obtains advisory services on an at-cost basis from
The Vanguard Group, Valley Forge, Pennsylvania 19482. For the fiscal year ended
December 31, 1998, Tax-Managed Growth and Income Fund and Tax-Managed Capital
Appreciation Fund paid advisory expenses of ________, and ____________, which
represented effective annual rates of ____, and _____. Tax-Managed Small-Cap
Fund began operations on February *, 1999, and advisory expenses for its first
fiscal year are estimated at an effective annual rate of ______.

The Funds have authorized the advisers to choose brokers or dealers to handle
the purchase and sale of securities for the Funds, and to get the best available
price and most favorable execution from these brokers with respect to all
transactions. Also, the Funds may direct the advisers to use a particular broker
for certain transactions in exchange for commission rebates or research services
provided to the Funds. However, the Group will not pay higher commissions
specifically for the purpose of obtaining research services.

YEAR 2000 CHALLENGE

The common practice in computer programming of using just two digits to identify
a year has resulted in the Year 2000 challenge throughout the information
technology industry. If unchanged, many computer applications and systems could
misinterpret dates occurring after December 31, 1999, leading to errors or
failure. Such failure could adversely affect a fund's operations, including
pricing, securities trading, and the servicing of shareholder accounts.

 The Vanguard Group is dedicated to providing uninterrupted, high-quality
performance from our computer systems before, during, and after 2000. In July
1998, we completed the renovation and initial testing of our internal systems.
Vanguard is diligently working with external partners, suppliers, and vendors,
including fund managers and other service providers, to assure that the systems
with which we interact remain operational at all times.

 In addition to taking every reasonable step to secure our internal systems and
external relationships, Vanguard is further developing contingency plans
intended to assure that unexpected systems failures will not adversely affect
the Funds' operations. Vanguard intends to monitor these processes through the
rollover of 1999 into 2000 and to quickly implement alternate solutions if
necessary.

 However, despite Vanguard's efforts and contingency plans, noncompliant
computer systems could have a material adverse effect on a Fund's business,
operations, or financial condition. Additionally, a Fund's performance could be
hurt if a computer-system failure at a company or governmental unit affects the
price of securities the Fund owns.


DIVIDENDS, CAPITAL GAINS, AND TAXES

Each December, the Tax-Managed Funds distribute to their shareholders virtually
all of their income from interest and dividends, as well as any capital gains
realized from the sale of its holdings. In addition, the Funds may occasionally
be required to make supplemental dividend or capital gains distributions at some
other time during the year.

 You can receive distributions of income or capital gains in cash, or you can
have them automatically invested in more shares of a Fund. In either case, these
distributions are taxable to you. It is important to note that distributions of
dividends and capital gains that are declared in December --if paid to you by
the end of January -- are taxed as if they had been paid to you in December.

 Vanguard will send you a statement each year showing the tax status of all your
distributions. If you have chosen to receive dividend and/or capital gains
distributions in cash, and the postal or other delivery service is unable to
deliver checks to your address of record, we will change the distribution option
so that all dividends and other distributions are automatically invested in
additional shares. We will not pay interest on uncashed distribution checks. 

- - The dividends and short-term capital gains that you receive are considered
    ordinary income for tax purposes.

- - Any distributions of net long-term capital gains by a Fund are taxable to you
    as long-term capital gains, no matter how long you've owned shares in the 
    Fund.

- - Although the Funds do not seek to realize any particular amount of capital 
    gains during a year, such gains are realized from time to time as 
    by-products of their ordinary investment activities. Consequently, 
    distributions may vary considerably from year to year.

- - If you sell or exchange shares, any gain or loss you have is a taxable event.
    This means that you may have a capital gain to report as income, or a 
    capital loss to report as a deduction, when you complete your federal 
    income tax return.
<PAGE>   51
- - Distributions of dividends or capital gains, and capital gains or losses from
  your sale or exchange of Fund shares, may be subject to state and local income
  taxes as well.

                                DISTRIBUTIONS

As a shareholder, you are entitled to your share of the fund's income from
interest and dividends, and gains from the sale of investments. You receive such
earnings as either an income dividend or a capital gains distribution. Income
dividends come from both the dividends that the fund earns from its holdings and
the interest it receives from its money market and bond investments. Capital
gains are realized whenever the fund sells securities for higher prices than it
paid for them. The capital gains are either short-term or long-term depending on
whether the fund held the securities for less than or more than one year.


                               PLAIN TALK ABOUT

                             "BUYING A DIVIDEND"

Unless you are investing through a tax-deferred retirement account (such as an
IRA), it is not to your advantage to buy shares of a fund shortly before it
makes a distribution, because doing so can cost you money in taxes. This is
known as "buying a dividend." For example: on December 15, you invest $5,000,
buying 250 shares for $20 each. If the fund pays a distribution of $1 per share
on December 16, its share price would drop to $19 (not counting market change).
You still have only $5,000 (250 shares x $19 = $4,750 in share value, plus 250
shares x $1 = $250 in distributions), but you owe tax on the $250 distribution
you received -- even if you reinvest it in more shares. To avoid "buying a
dividend," check a fund's distribution schedule before you invest.


SHARE PRICE

Each Fund's share price, called its net asset value, or NAV, is calculated each
business day after the close of trading on the New York Stock Exchange (the NAV
is not calculated on holidays or other days the Exchange is closed). Net asset
value per share is computed by adding up the total value of the Fund's
investments and other assets, subtracting any of its liabilities (debts), and
then dividing by the number of Fund shares outstanding:

                            TOTAL ASSETS   -   LIABILITIES
                            -------------------------------
  NET ASSET VALUE =          NUMBER OF SHARES OUTSTANDING

 Knowing the daily net asset value is useful to you as a shareholder because it
indicates the current value of your investment. The Fund's NAV, multiplied by
the number of shares you own, gives you the dollar amount you would have
received had you sold all of your shares back to the Fund that day.

 A NOTE ON PRICING: A Fund's investments will be priced at their market value
when market quotations are readily available. When these quotations are not
readily available, investments will be priced at their fair value, calculated
according to procedures adopted by the Board of Trustees.

  Each Fund's share price can be found daily in the mutual fund listings of most
major newspapers under the heading "Vanguard Funds." Different newspapers use
different abbreviations of the Funds' names, but the most common are ___________

                   HOW TO READ THE FINANCIAL HIGHLIGHTS TABLE

This explanation uses the Tax-Managed Capital Appreciation Fund as an example. 
The Fund began fiscal 1998 with a net asset value (price) of $20.18 per share.
During the semi-annual period, the Fund earned $ - per share from investment 
income (interest and dividends) and $ - per share from investments that had 
appreciated in value or that were sold for higher prices than the Fund paid for
them. 

Of those total earnings of $ - per share, $ - per share was returned to
shareholders in the form of dividend and capital gains distributions. 
<PAGE>   52
The earnings ($ - per share) minus the distributions ($ - per share) resulted in
a share price of $ - at the end of the year. This was an increase of $ - per
share (from $X at the beginning of the year to $ - at the end of the year). For
a shareholder who reinvested the distributions in the purchase of more shares,
the total return from the Fund was - % for the year.

As of December 31, 1998, the Fund had $ - billion in net assets; an expense
ratio of - % ($ - per $1,000 of net assets); and net investment income amounting
to - % of its average net assets. It sold and replaced securities valued at - %
of its total net assets.


FINANCIAL HIGHLIGHTS

The following financial highlights tables are intended to help you understand
each Fund's financial performance since its inception (except for Tax-Managed
Small-Cap Fund, which did not start until February *, 1999), and reflect
financial results for a single Fund share in each case. The total returns in
each table represent the BEFORE-TAX rate that an investor would have earned each
period on an investment in the Fund (assuming reinvestment of all dividends and
distributions, and complete redemption at the end of the period). Except for the
data relating the six-months ended June 30, 1998, this information has been
audited by PricewaterhouseCoopers LLP, independent accountants, whose report --
along with each Fund's financial statements -- is included in the Funds' most
recent annual report to shareholders.  You may have the annual or semi-annual

 From time to time, the Vanguard funds advertise yield and total return figures.
Yield is a measure of past dividend income. Total return includes both past
dividend income (assuming that it has been reinvested) plus realized and
unrealized capital appreciation (or depreciation). Neither yield nor total
return should be used to predict the future performance of a fund.

*You must obtain a Personal Identification Number through Tele-Account at least
seven days before you request your first exchange.

IMPORTANT NOTE: Once you've requested a telephone transaction and a confirmation
number has been assigned, the transaction cannot be revoked. We reserve the
right to refuse any purchase request.

     You can redeem (that is, sell or exchange) shares purchased by check at any
time. However, while your redemption request will be processed at the
next-determined net asset value after it is received, your redemption proceeds
will not be available until payment for your purchase is collected, which may
take up to ten calendar days.


A NOTE ON LARGE PURCHASES
It is important that you call Vanguard before you invest a large dollar amount.
We must consider the interests of all Fund shareholders and so reserve the right
to refuse any purchase that will disrupt the Fund's operation or performance.


REDEEMING SHARES
This section describes how you can redeem--that is, sell or exchange--the Funds'
shares.

     WHEN SELLING SHARES:
     - Vanguard sends the redemption proceeds to you or a designated third
party. (Proceeds sent to third parties or different addresses require a
signature guarantee; see footnote on page ___.)
     - You can sell all or part of your Fund shares at any time.

      WHEN EXCHANGING SHARES:
     - The redemption proceeds are used to purchase shares of a different
Vanguard fund.
     - You must meet the receiving fund's minimum investment requirements.
     - Vanguard reserves the right to revise or terminate the exchange
privilege, limit the amount of an exchange, or reject an exchange at any time,
without notice.
<PAGE>   58
In both cases, your transaction will be based on the Fund's next-determined
share price, subject to any special rules discussed in this prospectus. For
exchanges, the purchase side of the transaction will be based on the receiving
fund's next-determined share price, again subject to any special rules discussed
in this prospectus.


A NOTE ON REDEMPTION FEES
Each Fund imposes a 2% redemption fee on shares that are redeemed by any method
within one year of purchase. Each Fund imposes a 1% redemption fee on shares
that are redeemed by any method more than one year but less than five years of
purchase.


HOW TO REQUEST A REDEMPTION
You can request a redemption--that is, either a sale or exchange of shares--in
any one of three ways: Online, By Telephone, or By Mail.


ONLINE REQUESTS
ACCESS VANGUARD at www.vanguard.com
You can use your personal computer to sell or exchange shares of most Vanguard
funds by accessing our website. To establish this service, you must register
through the website. We will then send you, by mail, an account access password
that will enable you to sell or exchange shares online (as well as perform other
transactions).
     NOTE: The Vanguard funds whose shares you cannot exchange online or by
telephone are Vanguard U.S. Stock Index Funds, Vanguard Balanced Index Fund,
Vanguard International Stock Index Fund, Vanguard REIT Index Fund, Vanguard
Total International Stock Index Fund, and Vanguard Growth and Income Fund. If
you sell shares of these funds online, you will receive a redemption check at
your address of record.


TELEPHONE REQUESTS
Call Vanguard Tele-Account 24 hours a day--or your assigned Service Associate
during business hours--to sell or exchange shares. You can exchange shares from
this Fund to open an account in another Vanguard fund or to add to an existing
Vanguard fund account with an identical registration.

     SPECIAL INFORMATION: We will automatically establish the telephone
redemption option for your account, unless your instruct us otherwise in
writing. While telephone redemption is easy and convenient, this account feature
involves a risk of loss from unauthorized or fraudulent transactions. Vanguard
will take reasonable precautions to protect your account from fraud. You should
do the same by keeping your account information private and immediately
reviewing any account statements that we send to you. Make sure to contact
Vanguard immediately about any transaction you believe to be unauthorized.

     We reserve the right to refuse a telephone redemption if the caller is
unable to provide:
     - The ten-digit account number.
     - The name and address exactly as registered on the account.
     - The primary Social Security or employer identification number as
registered on the account.
     - The Personal Identification Number, if applicable.
     Please note that Vanguard will not be responsible for any account losses
due to telephone fraud, so long as we have taken reasonable steps to verify the
caller's identity. If you wish to remove the telephone redemption feature from
your account, please notify us in writing.


MAIL REQUESTS
Send a letter of instruction signed by all registered account holders. Include
the fund name and account number and (if you are selling) a dollar amount or
number of shares OR (if you are exchanging) the name of the fund you want to
exchange into and a dollar amount or number of shares. To exchange into an
account with a different registration (including a different name, address,
taxpayer identification number, or account type), you must provide Vanguard with
written instructions that include the guaranteed signatures of all current
account owners.


OPTIONS FOR REDEMPTION PROCEEDS
You may receive your redemption proceeds in one of two ways: check or exchange
to another Vanguard fund.

     CHECK REDEMPTIONS. Normally, Vanguard will mail your check within two
business days of a redemption.
<PAGE>   59
     EXCHANGE REDEMPTIONS. As described above, an exchange involves using the
proceeds of you redemption to purchase shares of another Vanguard fund.


FOR OUR MUTUAL PROTECTION

For your best interest and ours, Vanguard applies these additional requirements
to redemptions:

     REQUEST IN "GOOD ORDER." All redemption requests must be received by
Vanguard in "good order." This means that your request must include:

     - The Fund name and account number.
     - The amount of the transaction (in dollars or shares).
     - Signatures of all owners exactly as registered on the account (for mail
requests).
     - Signature guarantees (if required). *
     - Any supporting legal documentation that may be required.

*For instance, a signature guarantee must be provided for all registered
shareholders when redemption proceeds are to be sent to a different person or
address. A signature guarantee can be obtained from most banks, credit unions,
and licensed brokers.

TRANSACTIONS ARE PROCESSED AT THE NEXT-DETERMINED SHARE PRICE AFTER VANGUARD HAS
RECEIVED ALL REQUIRED INFORMATION.

     LIMITS ON ACCOUNT ACTIVITY. "Because excessive account transactions can
disrupt management of the Fund and increase the Fund's costs for all
shareholders, Vanguard limits account activity as follows:

     - You may make no more than TWO SUBSTANTIVE "ROUND TRIPS" THROUGH THE FUND
     during any 12-month period. o Your round trips through the Fund must be at
     least 30-days apart.
     - The Fund may refuse a share purchase at any time, for any reason.
     - Vanguard may revoke an investor's telephone exchange privilege at any
     time, for any reason.
 A "round trip" is a redemption from the Fund followed by a purchase back into
the Fund. Also, "round trip" covers transactions accomplished by any combination
methods, including transactions conducted by check, wire, or exchange to/from
another Vanguard fund. "Substantive" means a dollar amount that Vanguard
determines, in its sole discretion, could adversely affect management of the
Fund."

     ALL TRADES FINAL. Vanguard will not cancel any transaction request
(including any purchase or redemption) that we believe to be authentic once the
request has been received and a confirmation number assigned.

A NOTE ON UNUSUAL CIRCUMSTANCES
Vanguard reserves the right to revise or terminate the telephone redemption
privilege at any time, without notice. In addition, Vanguard can stop selling
shares or postpone payment at times when the New York Stock Exchange is closed
or under any emergency circumstances as determined by the U.S. Securities and
Exchange Commission. If you experience difficulty making a telephone redemption
during periods of drastic economic or market change, you can send us your
request by regular or express mail. Follow the instructions on selling or
exchanging shares by mail in the this section.


A NOTE ON LARGE REDEMPTIONS
It is important that you call Vanguard before you redeem a large dollar amount.
We must consider the interests of all Fund shareholders and so reserve the right
to delay delivery of your redemption proceeds -- up to seven days -- if the
amount will disrupt the Fund's operation or performance.
     If a shareholder redeems more than $250,000 worth of Fund shares within any
90-day period, the Fund reserves

the right to pay part or all of the redemption proceeds above $250,000 in kind,
i.e., in securities, rather than in cash. If payment is made in kind, the
shareholder may incur brokerage commissions if the shareholder elects to sell
the securities for cash.

FUND AND ACCOUNT UPDATES


STATEMENTS AND REPORTS
We will send you clear, concise account and tax statements to help you keep
track of your Fund account throughout the year as well as when you are preparing
your income tax returns.
     In addition, you will receive financial reports about the Fund twice a
year. These comprehensive reports include an assessment of the Fund's
performance (and a comparison to its industry benchmark), an overview of the
markets, a report from the advisers, a listing of the Fund's holdings, and other
financial statements.
     To keep the Fund's costs as low as possible (so that you and other
shareholders can keep more of the Fund's investment earnings), Vanguard attempts
to eliminate duplicate mailings to the same address. When we find that two or
more Fund shareholders have the same last name and address, we send just one
Fund report to that address -- instead of mailing separate reports to each
shareholder. If you want us to send separate reports, however, you may notify
our Institutional Division at 1-800-523-1036 or your assigned Service Associate.


CONFIRMATION STATEMENT
Sent each time you buy, sell, or exchange shares; confirms the trade date and
the amount of your transaction.

PORTFOLIO SUMMARY
Mailed quarterly for most accounts; shows the market value of your account at
the close of the statement period, as well as distributions, purchases, sales,
and exchanges for the current calendar year.

FUND FINANCIAL REPORTS
Mailed in February and August for this Fund.

TAX STATEMENTS
Generally mailed in January; report previous year's dividend and capital gains
distributions and proceeds from the sale of shares.

AVERAGE COST REVIEW STATEMENT

                            DESCRIPTION OF THE TRUST

ORGANIZATION

     The Trust was organized as a Maryland corporation in 1994, and was 
reorganized as a Delaware business trust in June, 1998. Prior to its 
reorganization as a Delaware business trust, the Trust was known as Vanguard 
Tax-Managed Fund, Inc. The Trust is registered with the United States 
Securities and Exchange Commission under the Investment Company Act of 1940 
(the "1940 Act") as an open-end diversified management investment company. It 
currently offers the following funds:
    

   
     Vanguard Tax-Managed Balanced Fund 
     Vanguard Tax-Managed Growth and Income Fund 
     Vanguard Tax-Managed Capital Appreciation Fund 
     Vanguard Tax-Managed Small-Cap Fund 

Each of the funds offers two classes of shares, an investor share class and an
institutional share class, with the exception of Vanguard Tax-Managed Balanced
Fund which has only an investor share class. (individually, the "Fund";
collectively, the "Funds") 
    

   
The Trust has the ability to offer additional series or classes of shares. 
There is no limit on the number of full and fractional shares that the Trust 
may issue for a single fund or class of shares.
    

   
SERVICE PROVIDERS

     Custodian. The Chase Manhattan Bank, N.A., 4 Chase MetroTech Center, 
Brooklyn, New York 11245, serves as the Trust's custodian. The custodian is 
responsible for maintaining the Trust's assets and keeping all necessary 
accounts and records.
    

   
     Independent Public Accountant. PricewaterhouseCoopers LLP, 30 South 17th 
Street, Philadelphia, Pennsylvania 19103, serves as the Trust's independent 
public accountant. The accountant audits the Trust's financial statements and 
provides other related services.
    

   
     Transfer and Dividend-Paying Agent. The Fund's transfer agent and 
dividend-paying agent is The Vanguard Group, Inc., 100 Vanguard Boulevard, 
Malvern, Pennsylvania 19355.
    

   
     CHARACTERISTICS OF THE TRUST'S SHARES

          Restrictions on Holding or Disposing of Shares. There are no 
     restrictions on the right of shareholders to retain or dispose of the 
     Trust's shares, other than the possible future termination of the Trust or
     any of its funds. The Trust or any of its funds may be terminated by
     reorganization into another mutual fund or by liquidation and distribution
     of the assets of the affected funds. Unless terminated by reorganization or
     liquidation, the Trust and its funds will continue indefinitely.
    

   
          Shareholder Liability. The Trust is organized under Delaware law,
     which provides that shareholders of a business trust are entitled to the
     same limitations of personal liability as shareholders of a corporation
     organized under Delaware law. Effectively, this means that a shareholder of
     the Trust will not be personally liable for payment of the Trust's debts
     except by reason of his or her own conduct or acts. In addition, a
     shareholder could incur a financial loss on account of a Trust obligation
     only if the Trust itself had no remaining assets with which to meet such
     obligation. We believe that the possibility of such a situation arising is
     extremely remote.
    

   
          Dividend Rights. The shareholders of a fund are entitled to receive
     any dividends or other distributions declared for such fund. No shares
     have priority or preference over any other shares of the same fund with
     respect to distributions. Distributions will be made from the assets of a
     fund, and will be paid ratably to all shareholders of the fund (or class)
     according to the number of shares of such fund (or class) held by
     shareholders on the record date. The amount of income dividends per share
     may vary between separate share classes of the same fund based upon
     differences in the way that expenses are allocated between share classes
     pursuant to a multiple class plan.
    

   
          Voting Rights. Shareholders are entitled to vote on a matter if: (i) a
     shareholder vote is required under the 1940 Act; (ii) the matter concerns
     an amendment to the Declaration of Trust that would adversely affect to a
     material degree the rights and preferences of the shares of any class or
     series; or (iii) the Trustees determine that it is necessary or desirable
     to obtain a shareholder vote. The 1940 Act requires a shareholder vote
     under various circumstances, including to elect or remove Trustees upon the
     written request of shareholders representing 10% or more of the Trust's net
     assets, and to change any fundamental policy of the Trust. Shareholders of
     the Trust receive one vote for each dollar of net asset value owned on the
     record date, and a fractional vote for each fractional dollar of net asset
     value owned on the record date. However, only the shares of the fund
     affected by a particular matter are entitled to vote on that matter. Voting
     rights are non-cumulative and cannot be modified without a majority vote of
     shareholders.
    

   
          Liquidation Rights. In the event of liquidation, shareholders will be
     entitled to receive a pro rata share of the net assets of applicable funds
     of the Trust.
    

   
          Preemptive Rights. There are no preemptive rights associated with the
     Trust.
    

   
          Conversion Rights. Shareholders of the Trust may convert their shares
     into another class of shares of the same funds upon the satisfaction of any
     then applicable eligibility requirements.
    

   
          Redemption Provisions. The Trust's redemption provisions are described
     in its current prospectus and elsewhere in this Statement of Additional
     Information.

          Sinking Fund Provisions. The Trust has no sinking fund provisions.

          Calls or Assessment. The Trust's shares are fully paid and 
     non-assessable.
    

   
          TAX STATUS OF THE TRUST

          Each Fund of the Trust qualifies as a "regulated investment company"
     under Subchapter M of the Internal Revenue Code. This special tax status
     means that a series will not be liable for federal tax on income and
     capital gains distributed to shareholders. In order to preserve its tax
     status, each Fund of the Trust must comply with certain requirements. If a
     Fund fails to meet these requirements in any taxable year, it will be
     subject to tax on its taxable income at corporate rates, and all
     distributions from earnings and profits, including any distributions of net
     tax-exempt income and net long-term capital gains, will be taxable to
     shareholders as ordinary income. In addition, the Fund could be required to
     recognize unrealized gains, pay substantial taxes and interest, and make
     substantial distributions before regaining its tax status as a regulated
     investment company.
    


   
                              INVESTMENT POLICIES
    

   
     The following policies supplement the investment objective and policies set
forth in the Trust's Prospectus:
    


REPURCHASE AGREEMENTS


   
     Each Fund of the Trust may invest in repurchase agreements with commercial
banks, brokers or dealers either for defensive purposes due to market conditions
or to generate income from its excess cash balances. A repurchase agreement is
an agreement under which a Fund acquires a money market instrument (generally a
security issued by the U.S. Government or an agency thereof, a banker's
acceptance or a certificate of deposit) from a commercial bank, broker or
dealer, subject to resale to the seller at an agreed upon price and date
(normally, the next business day). A repurchase agreement may be considered a
loan collateralized by securities. The resale price reflects an agreed upon
interest rate effective for the period the instrument is held by the Fund and is
unrelated to the interest rate on the underlying instrument. In these
transactions, the securities acquired by the Fund (including accrued interest
earned thereon) must have a total value in excess of the value of the repurchase
agreement and are held by a custodian bank until repurchased. In addition, the
Trust's Board of Trustees will monitor a Fund's repurchase agreement
transactions generally and will establish guidelines and standards for review by
the investment adviser of the creditworthiness of any bank, broker or dealer
party to a repurchase agreement with the Fund.
    

                                                                             B-1
<PAGE>   64
   
     The use of repurchase agreements involves certain risks. For example, if
the other party to the agreement defaults on its obligation to repurchase the
underlying security at a time when the value of the security has declined, the
Fund may incur a loss upon disposition of the security. If the other party to
the agreement becomes insolvent and subject to liquidation or reorganization
under the Bankruptcy Code or other laws, a court may determine that the
underlying security is collateral for a loan by the Fund not within the control
of the Fund and therefore the realization by the Fund on such collateral may be
automatically stayed. Finally, it is possible that the Fund may not be able to
substantiate its interest in the underlying security and may be deemed an
unsecured creditor of the other party to the agreement. While each Fund's
management acknowledges these risks, it is expected that they can be controlled
through careful monitoring procedures.
    


   
     LENDING OF SECURITIES. Each Fund of the Trust may lend its investment
securities to qualified institutional investors (typically brokers, dealers,
banks or other financial institutions) who need to borrow securities in order to
complete certain transactions, such as covering short sales, avoiding failures
to deliver securities or completing arbitrage operations. By lending its
investment securities, a Fund attempts to increase its net investment income
through the receipt of interest on the loan. Any gain or loss in the market
price of the securities loaned that might occur during the term of the loan
would be for the account of the Fund. The terms and the structure and the
aggregate amount of such loans must be consistent with the Investment Company
Act of 1940, and the Rules and Regulations or interpretations of the Securities
and Exchange Commission (the "Commission") thereunder. These provisions limit
the amount of securities a Fund may lend to 33 1/3% of the Fund's total assets,
and require that (a) the borrower pledge and maintain with the Fund collateral
consisting of cash, an irrevocable letter of credit or securities issued or
guaranteed by the United States Government having at all times not less than
100% of the value of the securities loaned, (b) the borrower add to such
collateral whenever the price of the securities loaned rises (i.e., the borrower
"marks to the market" on a daily basis), (c) the loan be made subject to
termination by the Fund at any time, and (d) the Fund receive reasonable
interest on the loan (which may include the Fund's investing any cash collateral
in interest bearing short-term investments), any distribution on the loaned
securities and any increase in their market value. Loan arrangements made by
each Fund will comply with all other applicable regulatory requirements,
including the rules of the New York Stock Exchange, which presently require the
borrower, after notice, to redeliver the securities within the normal settlement
time of three business days. All relevant facts and circumstances, including the
creditworthiness of the broker, dealer or institution, will be considered in
making decisions with respect to the lending of securities, subject to review by
the Trust's Board of Trustees.
    

   
     At the present time, the Staff of the Commission does not object if an 
investment company pays reasonable negotiated fees in connection with loaned 
securities, so long as such fees are set forth in a written contract and 
approved by the investment company's Trustees. In addition, voting rights pass 
with the loaned securities, but if a material event will occur affecting an 
investment on loan, the loan must be called and the securities voted.
    

   
    

   
VANGUARD INTERFUND LENDING PROGRAM. The SEC has issued an exemptive order 
permitting the Funds to participate in Vanguard's interfund lending program. 
This program allows the Vanguard funds to borrow money from and loan money to 
each other for temporary or emergency purposes. The program is subject to a 
number of conditions, including the requirement that no fund may borrow or lend 
money through the program unless it receives a more favorable interest rate 
than is available from a typical bank for a comparable transaction. In 
addition, a fund may participate in the program only if and to the extent that 
such participation is consistent with the fund's investment objective and other 
investment policies. The Boards of Trustees of the Vanguard funds are 
responsible for ensuring that the interfund lending program operates in 
compliance with all conditions of the SEC's exemptive order.
    

   
ILLIQUID SECURITIES
    

   
     Each Fund may invest up to 15% of its net assets in illiquid securities.
Illiquid securities are securities that may not be sold or disposed of in the
ordinary course of business within seven business days at approximately the
value at which they are being carried on the Fund's books.
    

   
     Each Fund may invest in restricted, privately placed securities that, 
under SEC rules, may be sold only to qualified institutional buyers. Because 
these securities can be resold only to qualified institutional buyers, they may 
be considered illiquid securities -- meaning that they could be difficult for 
the Fund to convert to cash if needed.
    

   
     If a substantial market develops for a restricted security held by the
Fund, it will be treated as a liquid security, in accordance with procedures and
guidelines approved by the Fund's Board of Trustees. While the Fund's investment
adviser determines the liquidity of restricted securities on a daily basis, the
Board oversees and retains ultimate responsibility for the adviser's decisions.
Several factors the Board considers in monitoring these decisions include the
valuation of a security, the availability of qualified institutional buyers, and
the availability of information about the security's issuer.

FUTURES CONTRACTS, OPTIONS ON FUTURES CONTRACTS, WARRANTS, CONVERTIBLE
SECURITIES AND SWAP AGREEMENTS

   
     Each Fund of the Trust may enter into futures contracts, options, and
options on futures contracts for several reasons: to simulate full investment in
the underlying securities while retaining a cash balance for Fund management
purposes, to facilitate trading, or to reduce transaction costs. Futures
contracts provide for the future sale by one party and purchase by another party
of a specified amount of a specific security at a specified future time and at a
specified price. Futures contracts which are standardized as to maturity date
and underlying financial instrument are traded on national futures exchanges.
Futures exchanges and trading are regulated under the Commodity Exchange Act by
the Commodity Futures Trading Commission ("CFTC"), a U.S. Government Agency.
Assets committed to futures contracts will be segregated to the extent required
by law.
    

     Most futures contracts are closed out before the settlement date without
the making or taking of delivery. Closing out an open futures position is done
by taking an opposite position ("buying" a contract which has previously been
"sold," or "selling" a contract previously purchased) in an identical contract
to terminate the position. Brokerage commissions are incurred when a futures
contract is bought or sold.

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

   
     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, change in the
contract value may reduce the required margin, resulting in a repayment of
excess margin to the contract holder. Variation margin payments are made to and
from the futures broker for as long as the contract remains open. The Trust
expects to earn interest income on its initial margin deposit.
    

   
     Traders in futures contracts may be broadly classified as either "hedgers"
or "speculators." Hedgers use the futures markets primarily to offset
unfavorable changes in the value of securities otherwise held for investment
purposes or expected to be acquired by them. Speculators are less inclined to
own the securities underlying the futures contracts which they trade, and use
futures contracts with the expectation of realizing profits from fluctuations in
the prices of underlying securities. Under CFTC regulations, the Funds may
use futures transactions for bona fide hedging purposes only, except that a
Fund may establish non-hedging futures positions if the aggregate initial
margin and premiums for such positions do not exceed five percent of the value
of the Fund's assets.
    

   
     Although techniques other than the sale and purchase of futures contracts
could be used to control a Fund's exposure to market fluctuations, the use
of futures contracts may be a more effective means of hedging this exposure.
    


RESTRICTIONS ON THE USE OF FUTURES CONTRACTS

   
     A Fund of the Trust will not enter into futures contract transactions
to the extent that, immediately thereafter, the sum of its initial margin
deposits on open contracts exceeds 5% of the market value
    

                                                                             B-3
<PAGE>   66
   
of the Fund's total assets. In addition, a Fund will not enter into futures
contracts to the extent that its outstanding obligations to purchase securities
under these contracts would exceed 20% of its total assets.
    


RISK FACTORS IN FUTURES TRANSACTIONS

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

   
     A Fund will minimize the risk that it will be unable to close out a
futures contract by only entering into futures which are traded on national
futures exchanges and for which there appears to be a liquid secondary market.
    

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

   
     Utilization of futures transactions by a Fund does involve the risk of
imperfect or no correlation where the securities underlying futures contracts
have different maturities than the portfolio securities being hedged. It is also
possible that a Fund could both lose money on futures contracts and also
experience a decline in value of its portfolio securities. There is also the
risk of loss by each Fund of margin deposits in the event of bankruptcy of a
broker with whom a Fund has an open position in a futures contract or related
option.
    

     Most futures exchanges limit the amount of fluctuation permitted in futures
contract prices during a single trading day. The daily limit establishes the
maximum amount that the price of a futures contract may vary either up or down
from the previous day's settlement price at the end of a trading session. Once
the daily limit has been reached in a particular type of contract, no trades may
be made on that day at a price beyond that limit. The daily limit governs only
price movement during a particular trading day and therefore does not limit
potential losses, because the limit may prevent the liquidation of unfavorable
positions. Futures contract prices have occasionally moved to the daily limit
for several consecutive trading days with little or no trading, thereby
preventing prompt liquidation of future positions and subjecting some futures
traders to substantial losses.

OTHER TYPES OF DERIVATIVES

   
     In addition to futures and options, a Fund may invest in other types
of derivatives, including warrants, swap agreements and partnerships or grantor
trust derivative products. Derivatives are instruments whose value is linked to
or derived from an underlying security. Derivatives may be traded separately on
exchanges or in the over-the-counter market, or they may be imbedded in
securities. The most common imbedded derivative is the call option attached to,
or imbedded in, a callable bond. The owner of a traditional callable bond holds
a combination of a long position in a non-callable bond and a short position in
a call option on that bond.
    

   
     Derivative instruments may be used individually or in combination to hedge
against unfavorable changes in interest rates, or to take advantage of
anticipated changes in interest rates. Derivatives may be structured with no or
a high degree of leverage. When derivatives are used as hedges, the risk
incurred is that the derivative instrument's value may change differently than
the value of the security being hedged. This "basis risk" is generally lower
than the risk associated with an unhedged position in the security being hedged.
Some derivatives may entail liquidity risk, i.e., the risk that the instrument
cannot be sold at a reasonable price in highly volatile markets. Leveraged
derivatives used for speculation are very volatile, and therefore, very risky.
However, the Funds will only utilize derivatives for hedging or arbitrage
purposes, and not for speculative purposes. Over-the-counter derivatives involve
a counterparty risk, i.e., the risk that the individual or institution on the
other side of the agreement will not or cannot meet their obligations under the
derivative agreement.
    


FEDERAL TAX TREATMENT OF FUTURES CONTRACTS AND OTHER FEDERAL TAX MATTERS

   
     Except for transactions a Fund has identified as hedging transactions,
the Fund is required for federal income tax purposes to recognize as income
for each taxable year its net unrealized gains and losses on certain futures
contracts as of the end of the year as well as those actually realized during
the year. In most cases, any gain or loss recognized with respect to a futures
contract is considered to be 60% long-term capital gain or loss and 40%
short-term capital gain or loss, without regard to the holding period of the
contract. Furthermore, sales of futures contracts which are intended to hedge
against a change in the value of securities held by a Fund may affect the
holding period of such securities and, consequently, the nature of the gain or
loss on such securities upon disposition. A Fund 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 Fund.
    

   
     In order for a Fund to continue to qualify for federal income tax treatment
as a regulated investment company, at least 90% of its gross income for a
taxable year must be derived from qualifying income; i.e., dividends, interest,
income derived from loans of securities, gains from the sale of securities or of
foreign currencies or other income derived with respect to the Fund's business
of investing in securities. It is anticipated that any net gain realized from
the closing out of futures contracts will be considered qualifying income for
purposes of the 90% requirement.
    

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

Non-Investment Grade Purchases

   
     The Balanced Fund will invest 50-55% of its assets in
intermediate-term municipal securities which provide interest exempt from
federal income taxes.
    

                                                                             B-5
<PAGE>   68
   
     At least 75% of the municipal securities held by the Tax-Managed Balanced
Fund must be rated in one of the top three ratings categories (Aaa, Aa, and
A for Moody's, or AAA, AA, and A for Standard & Poor's). No more than 25% of the
Fund will be invested in bonds rated Baa (by Moody's) or BBB (by Standard &
Poor's.) Of that 25%, 5% may be lower-rated or unrated. Bonds rated below Baa
(by Moody's) or BBB (by Standard & Poor's), may include bonds rated as low as C
(by Moody's) or D (by Standard & Poor's.)
    

   
     In the event that a particular municipal security held by the Fund is
downgraded below the minimum investment level permitted by the Fund's investment
policies, the Trustees and Officers of the Trust will carefully assess the
creditworthiness of the obligation to determine whether it continues to meet the
policies and objectives of the Fund.
    


MUNICIPAL LEASE OBLIGATIONS

   
     Each Fund of the Trust may invest in municipal lease obligations. These
securities are sometimes considered illiquid because of the inefficiency and
thinness of the market in which they are traded. Under the supervision of the
Trust's Board of Trustees, the Fixed Income Group may determine to treat certain
municipal lease obligations as liquid, and therefore not subject to the Trust's
15% limit on illiquid securities. The factors that the Fixed Income Group may
consider in making these liquidity determinations include: (1) the frequency of
trades and quotations for the security; (2) the number of dealers willing to
purchase or sell the security and the number of other potential buyers; (3) the
willingness of dealers to underwrite and make a market in the security; (4) the
nature of the marketplace trades, including the time needed to dispose of the
security, the method of soliciting offers, and the mechanics of transfer; and
(5) factors unique to a particular security, including general creditworthiness
of the issuer, the importance to the issuer of the property covered by the lease
and the likelihood that the marketability of the securities will be maintained
throughout the time the security is held by the Fund.
    

     In the case of any unrated municipal lease obligations, a Fixed Income
Group analyst will assign a credit rating based upon criteria that include an
analysis of factors similar to those considered by nationally recognized
statistical rating organizations. In addition, the Fixed Income Group's
liquidity determinations will incorporate those factors mentioned above.


                               PURCHASE OF SHARES

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


                              REDEMPTION OF SHARES

   
     Each Fund of the Trust may suspend redemption privileges or postpone the
date of payment: (i) during any period that the New York Stock Exchange is
closed, or trading on the Exchange is restricted as determined by the Securities
and Exchange Commission (the "Commission"), (ii) during any period when an
emergency exists as defined by the rules of the Commission as a result of which
it is not reasonably practicable for a 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.
    

   
     The Trust has made an election with the Commission to pay in cash all
redemptions requested by any shareholder of record limited in amount during any
90-day period to the lesser of $250,000 or 1% of the net assets of the Trust at
the beginning of such period. Such commitment is irrevocable without
    

B-6
<PAGE>   69
   
the prior approval of the Commission. Redemptions in excess of the above limits
may be paid in whole or in part, in readily marketable investment securities or
in cash, as the Trustees may deem advisable; however, payment will be made
wholly in cash unless the Trustees believe that economic or market conditions
exist which would make such a practice detrimental to the best interests of the
Trust. If redemptions are paid in investment securities, such securities will be
valued as set forth in the Prospectus under "The Share Price of Each Portfolio"
and a redeeming shareholder would normally incur brokerage expenses if he
converted these securities to cash.
    

   
     A redemption fee of 2% of the value of a Fund's shares redeemed will be
deducted from the redemption proceeds if shares held for less than one year are
redeemed. A redemption fee of 1% of the value of shares redeemed will be
deducted from the redemption proceeds if shares held for at least one year but
less than five years are redeemed. These fees are paid directly to the Trust.
Any redemption may be more or less than the shareholder's cost depending on the
market value of the securities held by a Fund. In the event of an early
redemption due to a shareholder's death, all redemption fees will be waived. In
order to substantiate the death, a certified copy of the death certificate must
be provided.
    

SIGNATURE GUARANTEES

   
     To protect your account, the Trust and Vanguard from fraud, signature
guarantees are required for certain redemptions. Signature guarantees enable the
Trust to verify the identity of the person who has authorized a redemption from
your account. SIGNATURE GUARANTEES ARE REQUIRED IN CONNECTION WITH: (1) ALL
REDEMPTIONS, REGARDLESS OF THE AMOUNT INVOLVED, WHEN THE PROCEEDS ARE TO BE PAID
TO SOMEONE OTHER THAN THE REGISTERED OWNER(S), AND/OR TO AN ADDRESS OTHER THAN
THE ADDRESS OF RECORD; AND (2) SHARE TRANSFER REQUESTS.
    

     A signature guarantor must be a bank, broker, or any other guarantor that
Vanguard deems acceptable. NOTARIES PUBLIC ARE NOT ACCEPTABLE SIGNATURE
GUARANTORS.

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

   
    

   
                                  SHARE PRICE

     The Fund's share price or "net asset value" per share is calculated by 
dividing the total assets of the Fund less all liabilities by the total number 
of shares outstanding. The net asset value is determined as of the close of the 
New York Stock Exchange (generally 4:00 p.m. Eastern time) on each day that the 
Exchange is open for trading.

     Portfolio securities for which market quotations are readily available 
(includes those securities listed on national securities exchanges, as well as 
those quoted on the NASDAQ Stock Market) will be valued at the last quoted 
sales price on the day the valuation is made. Such securities which are not 
traded on the valuation date are valued at the mean of the bid and ask prices. 
Price information on exchange-listed securities is taken from the exchange 
where the security is primarily traded. Any foreign securities are valued at 
the latest quoted sales price available before the time when assets are valued. 
Securities may be valued on the basis of prices provided by a pricing service 
when such prices are believed to reflect the fair market value of such 
securities. 

     Short-term instruments (those acquired with remaining maturities of 60 
days or less) may be valued at cost, plus or minus any amortized discount or 
premium, which approximates market value.

     Bonds and other fixed income securities may be valued on the basis of
prices provided by a pricing service when such prices are believed to reflect
the fair market value of such securities. The prices provided by a pricing
service may be determined without regard to bid or last sale prices of each
security, but take into account institutional-size transactions in similar
groups of securities as well as any developments related to specific securities.

                       FUNDAMENTAL INVESTMENT LIMITATIONS

The Funds are subject to the following fundamental investment limitations, which
cannot be changed in any material way without the approval of the holders of a
majority of a Fund's shares. For these purposes, a "majority" of a Fund's shares
means shares representing the lesser of: (i) 67% or more of the Fund's net asset
value, so long as shares representing more than 50% of the Fund's net asset
value are present or represented by proxy; or (ii) more than 50% of the Fund's
net asset value.

     BORROWING.  The Fund may not borrow money, except for temporary or 
emergency purposes in an amount not exceeding 15% of the Fund's net assets. The 
Fund may borrow money through banks, reverse repurchase agreements, or 
Vanguard's interfund lending program only, and must comply with all applicable 
regulatory conditions. The Fund may not make any additional investments 
whenever its outstanding borrowings exceed 5% of net assets.

     COMMODITIES.  The Fund may not invest in commodities or commodity 
contracts, except that it may invest in stock and bond futures contracts, 
options, and options on futures contracts. No more than 3% of the Fund's assets 
may be used as initial margin deposit for futures contracts, and no more than 
5% of the Fund's assets may be invested in futures contracts at any time.

     DIVERSIFICATION.  With respect to 75% of its total assets, the Fund may 
not; (i) purchase more than 10% of the outstanding voting securities of any one 
issuer; or (ii) purchase securities of any issuer if, as a result, more than 5% 
of the Fund's total assets would be invested in that issuer's securities. This 
limitation does not apply to obligations of the United States Government, its 
agencies, or instrumentalities.

     ILLIQUID SECURITIES.  The Fund may not acquire any security if, as a 
result, more than 15% of its net assets would be invested in securities that 
are illiquid.

     INDUSTRY CONCENTRATION.  The Fund may not invest more than 25% of its 
total assets in any one industry.

     INVESTING FOR CONTROL.  The Fund may not invest in a company for purposes 
of controlling its management.

     INVESTMENT COMPANIES.  The Fund may not invest in any other investment 
company, except through a merger, consolidation or acquisition of assets 
approved by the Fund's shareholders, or to the extent permitted by Section 12 
of the 1940 Act. Investment companies whose shares the Fund acquires pursuant 
to Section 12 must have investment objectives and investment policies 
consistent with those of the Fund.

     LOANS.  The Fund may not lend money to any person except by purchasing 
fixed income securities that are publicly distributed or customarily purchased 
by institutional investors, by lending its portfolio securities, or through 
Vanguard's interfund lending program.

     MARGIN.  The Fund may not purchase securities on margin or sell securities 
short, except as permitted by the Fund's investment policies relating to 
commodities.
    

     B-8

<PAGE>   71
   
     PLEDGING ASSETS.  The Fund may not pledge, mortgage or hypothecate more 
than 15% of its net assets.

     REAL ESTATE.  The Fund may not invest directly in real estate, although it 
may invest in securities of companies that deal in real estate and, in the case 
of Tax-Managed Balanced Fund, bonds secured by real estate.

     SENIOR SECURITIES.  The Fund may not issue senior securities, except in 
compliance with the 1940 Act.

     UNDERWRITING.  The Fund may not engage in the business of underwriting 
securities issued by other persons. The Fund will not be considered an 
underwriter when disposing of its investment securities.

None of these limitations prevents the Fund from participating in The Vanguard 
Group ("Vanguard"). Because the Trust is a member of the Group, the Funds may 
own securities issued by Vanguard, make loans to Vanguard, and contribute to 
Vanguard's costs or other financial requirement. See "Management of the Trust" 
for more information. Unless otherwise stated, each of the above limitations 
applies at the time securities are purchased.
    

                                                                             B-9

                               THE VANGUARD GROUP

   
     Vanguard Tax-Managed Funds are a member of The Vanguard Group of Investment
Companies which consists of more than 30 investment companies (the "Trusts").
Through their jointly-owned subsidiary, The Vanguard Group, Inc. ("Vanguard"),
the Trust and the other Trusts in The Vanguard Group obtain at cost virtually
all of their corporate management, administrative and distribution services.
Vanguard also provides investment advisory services on an at-cost basis to
certain of the Vanguard Trusts including Vanguard Tax-Managed Fund.
    

   
     Vanguard employs a supporting staff of management and administrative
personnel needed to provide the requisite services to the Trusts and also
furnishes the Trusts with necessary office space, furnishings and equipment.
Each Trust pays its share of Vanguard's net expenses which are allocated among
the Trusts under methods approved by the Board of Trustees of each Trust. In
addition, each Trust bears its own direct expenses, such as legal, auditing and
custodian fees.
    

   
     Vanguard adheres to a Code of Ethics established pursuant to Rule 17j-1
under the Investment Company Act of 1940. The Code is designed to prevent
unlawful practices in connection with the purchase or sale of securities by
persons associated with Vanguard. Under Vanguard's Code of Ethics certain
Officers and employees of Vanguard who are considered access persons are
permitted to engage in personal securities transactions. However, such
transactions are subject to procedures and guidelines similar to, and in many
cases more restrictive than, those recommended by a blue ribbon panel of mutual
fund industry executives.
    

   
     Vanguard was established and operates under an Amended and Restated Funds'
Service Agreement which was approved by the shareholders of each of the Trusts.
The amounts which each of the Trusts has invested are adjusted from time to time
in order to maintain the proportionate relationship between each Trust's
relative net assets and its contribution to Vanguard's capital. The Amended and
Restated Funds' Service Agreement provides for the following arrangement: (1)
each Vanguard Trust may invest a maximum of 0.40% of its assets in Vanguard and
(2) there is no restriction on the maximum cash investment that the Vanguard
Trusts may make in Vanguard. At December 31, 1998, the Trust had contributed
capital of $   *    to Vanguard, representing    *   % of Vanguard's
capitalization.
    

   
     MANAGEMENT. Corporate management and administrative services include: (1)
executive staff; (2) accounting and financial; (3) legal and regulatory; (4)
shareholder account maintenance; (5) monitoring and control of custodian
relationships; (6) shareholder reporting; and (7) review and evaluation of
advisory and other services provided to the Trusts by third parties. During the
six months ended December 31, 1998, the Trust's allocated share of Vanguard's
actual net costs of operation relating to management and administrative services
(including transfer agency) totaled approximately $   *    .
    

   
     DISTRIBUTION. 
    

   
     Vanguard Marketing Corporation, a wholly-owned Subsidiary of The Vanguard
Group, Inc., provides all distribution and marketing activities for the Trusts
in the Group. The principal distribution expenses are for advertising,
promotional materials and marketing personnel. Distribution services may also
include organizing and offering to the public, from time to time, one or more
new investment companies which will become members of The Vanguard Group. The
Trustees and Officers of Vanguard determine the amount to be spent annually on
distribution activities, the manner and amount to be spent on each Trust, and
whether to organize new investment companies.
    

   
     One half of the distribution expenses of a marketing and promotional nature
is allocated among the Trusts based upon their relative net assets. The
remaining one half of these expenses is allocated among the Trusts based upon
each Trust's sales for the preceding 24 months relative to the total sales of
the Trusts as a Group, provided, however, that no Trust's aggregate quarterly
rate of contribution for distribution expenses of a marketing and promotional
nature shall exceed 125% of the average distri-
    

                                                                            B-11
<PAGE>   74
   
bution expense rate for The Vanguard Group, and that no Trust shall incur annual
distribution expenses in excess of 20/100 of 1% of its average month-end net
assets. During the fiscal year ended December 31, 1998, the Trust paid
approximately $- of the The Vanguard Group's distribution and marketing 
expenses.
    

   
     INVESTMENT ADVISORY SERVICES. Vanguard's Core Management Group provides
investment advisory services to the Trust. These services are provided on an
at-cost basis by Vanguard's Core Management Group and Vanguard's Fixed Income
Group. The compensation and other expenses of this staff are paid by the funds
and Trusts utilizing these services. During the fiscal year ended December 31,
1998, the Trust paid approximately $    *    of Vanguard's expenses relating to
investment advisory services.
    

   
TRUSTEE COMPENSATION
    

   
     The individuals in the following table serve as Trustees of all Vanguard
Trusts, and each Trust pays a proportionate share of the Trustees' compensation.
The Trusts employ their Officers on a shared basis, as well. However, Officers
are compensated by The Vanguard Group, Inc., not the Trusts.
    

   
     INDEPENDENT TRUSTEES. The Trusts compensate their independent
Trustees--that is, the ones who are not also Officers of the Trust--in three
ways:
    

   
     -    The independent Trustees receive an annual fee for their service to
          the Trusts, which is subject to reduction based on absences from
          scheduled Board meetings.
    

   
     -    The independent Trustees are reimbursed for the travel and other
          expenses that they incur in attending Board meetings.
    

   
     -    Upon retirement, the independent Trustees receive an aggregate annual
          fee of $1,000 for each year served on the Board, up to fifteen years
          of service. This annual fee is paid for ten years following
          retirement, or until each Trustee's death.
    

   
     "INTERESTED" TRUSTEES. The Trust's interested Trustees--Messrs. Bogle and
Brennan--receive no compensation for their service in that capacity. However,
they are paid in their role as Officers of The Vanguard Group, Inc.
    

   
     COMPENSATION TABLE. The following table provides compensation details for
each of the Trustees. For the Trust, we list the amounts paid as compensation
and accrued as retirement benefits by the Trust for each Trustee. In addition,
the table shows the total amount of benefits that we expect each Trustee to

                             PORTFOLIO TRANSACTIONS

   
     In placing portfolio transactions, Vanguard uses its best judgment to
choose the broker most capable of providing the brokerage services necessary to
obtain best available price and most favorable execution. The full range and
quality of brokerage services available are considered in making these
determinations. In those instances where it is reasonably determined that more
than one broker can offer the brokerage services needed to obtain the best
available price and most favorable execution, consideration will be given to
those brokers which supply statistical information and provide other services in
addition to execution services to the Fund.
    

   
    

   
     During the periods ended December 31, 1996, 1997, and 1998,  the Fund paid
$203,672, $176,637, and $    *     in brokerage commissions, respectively.

          APPENDIX A--DESCRIPTION OF MUNICIPAL BONDS AND THEIR RATINGS

   
     Vanguard Tax-Managed Balanced Fund invests 50-55% of its assets in 
municipal bonds and other municipal securities.
    

   
    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
obligation" and "revenue" or "special tax" bonds. General obligation bonds are
secured by the issuer's pledge of its full faith, credit and taxing power for
the payment of principal and interest. Revenue or special tax bonds are payable
only from the revenues derived from a particular facility or class of facilities
or, in some cases, from the proceeds of a special excise or other tax, but not
from general tax revenues. The Trust may also invest in tax-exempt industrial
development bonds, short-term municipal obligations, demand notes and tax-exempt
commercial papers.
    

     Industrial revenue bonds in most cases are revenue bonds and generally do
not have the pledge of the credit of the issuer. The payment of the principal
and interest on such industrial revenue bonds is dependent solely on the ability
of the user of the facilities financed by the bonds to meet its financial
obligations and the pledge, if any, of real and personal property so financed as
security for such payment. Short-term municipal obligations issued by states,
cities, municipalities or municipal agencies, include Tax Anticipation Notes,
Revenue Anticipation Notes, Bond Anticipation Notes, Construction Loan Notes and
Short-Term Discount Notes.

     Note obligations with demand or put options may have a stated maturity in
excess of one year, but permit any holder to demand payment of principal plus
accrued interest upon a specified number of days' notice. Frequently, such
obligations are secured by letters of credit or other credit support
arrangements provided by banks. The issuer of such notes normally has a
corresponding right, after a given period, to repay in its discretion the
outstanding principal of the note plus accrued interest upon a specific number
of days' notice to the bondholders. The interest rate on a demand note may be
based upon a known lending rate, such as a bank's prime rate, and be adjusted
when such rate changes, or the interest rate on a demand note may be a market
rate that is adjusted at specified intervals. The demand notes in which the Fund
will invest are payable on not more than 397 days' notice. Each note purchased
by the Fund will meet the quality criteria set out above for the Fund.

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

   
    The Funds may purchase municipal bonds subject to so-called "demand
features." In such cases the Funds may purchase a security that is nominally
long-term, but has many of the features of shorter-term securities. By virtue of
this demand feature, the security will be deemed to have a maturity date that is
earlier than its stated maturity rate.
    


     B-18
<PAGE>   81
   
     Municipal Bonds are sometimes purchased on a "when issued" basis meaning
the Trust has committed to purchasing certain specified securities at an agreed
upon price when they are issued. The period between commitment date and issuance
date can be a month or more. It is possible that the securities will never be
issued and the commitment canceled.
    

   
     From time to time proposals have been introduced before Congress to
restrict or eliminate the Federal income tax exemption for interest on Municipal
Bonds. Similar proposals may be introduced in the future. If any such proposal
were enacted, it might restrict or eliminate the ability of the Trust to achieve
its investment objective. In that event, the Trust's Trustees and Officers would
reevaluate its investment objective and policies and consider recommending to
its shareholders changes in such objective and policies.
    

   
     Similarly, from time to time proposals have been introduced before State
and local legislatures to restrict or eliminate the State and local income tax
exemption for interest on Municipal Bonds. Similar proposals may be introduced
in the future. If any such proposal were enacted, it might restrict or eliminate
the ability of each Fund to achieve its respective investment objective. In
that event, the Trust's Trustees and Officers would reevaluate its investment
objective and policies and consider recommending to its shareholders changes in
such objectives and policies.
    

     Excerpts from Moody's Investors Service, Inc.'s Municipal Bond ratings:
Aaa--judged to be of the "best quality" and are referred to as "gilt edge";
interest payments are protected by a large or by an exceptionally stable margin
and principal is secure; Aa--judged to be of "high quality by all standards" but
as to which margins of protection or other elements make long-term risks appear
somewhat larger than Aaa-rated Municipal Bonds; together with Aaa group they
comprise what are generally known as "high grade bonds"; A--possess many
favorable investment attributes and are considered "upper medium grade
obligations." Factors giving security to principal and interest of A-rated
Municipal Bonds are considered adequate, but elements may be present which
suggest a susceptibility to impairment sometime in the future; Baa--considered
as medium grade obligations; i.e., they are neither highly protected nor poorly
secured; interest payments and principal security appear adequate for the
present but certain protective elements may be lacking or may be
characteristically unreliable over any great length of time; Ba--protection of
principal and interest payments may be very moderate; judged to have speculative
elements; their future cannot be considered as well-assured; B--lack
characteristics of a desirable investment; assurance of interest and principal
payments over any long period of time may be small; Caa--poor standing; may be
in default or there may be present elements of danger with respect to principal
and interest; Ca--speculative in a high degree; often in default; C--lowest
rated class of bonds; issues so rated can be regarded as having extremely poor
prospects for ever attaining any real investment standing.

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

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

     Excerpts from Standard & Poor's Corporation's Municipal Bond ratings:
AAA--has the highest rating assigned by S&P; extremely strong capacity to pay
principal and interest; AA--has a very strong capacity to pay interest and repay
principal and differs from the highest 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

B-20

<PAGE>   82
capacity to pay principal and interest; normally exhibit adequate protection
parameters but adverse economic conditions or changing circumstances are more
likely to lead to a weakened capacity to pay principal and interest than for
bonds in A category; BB--B--CCC--CC--predominantly speculative with respect to
capacity to pay interest and repay principal in accordance with terms of
obligations; BB is being paid; D--in default, and payment of principal and/or

ITEM 25. INDEMNIFICATION
    

   
     The Registrant's organizational documents contain provisions indemnifying
Trustees and Officers against liability incurred in their official capacity.
Article VII, Section 2 of the Declaration of Trust provides that the Registrant
may indemnify and hold harmless each and every Trustee and Officer from and
against any and all claims, demands, costs, losses, expenses, and damages
whatsoever arising out of or related to the performance of his or her duties as
a Trustee or Officer. However, this provision does not cover any liability to
which a Trustee or Officer would otherwise be subject by reason of willful
misfeasance, bad faith, gross negligence or reckless disregard of the duties
involved in the conduct of his or her office. Article VI of the By-Laws
generally provides that the Registrant shall indemnify its Trustees and Officers
from any liability arising out of their past or present service in that
capacity. Among other things, this provision excludes any liability arising by
reason of willful misfeasance, bad faith, gross negligence, or the reckless
disregard of the duties involved in the conduct of the Trustee's or Officer's
office with the Registrant.

                           VANGUARD TAX-MANAGED FUNDS

                   MULTIPLE CLASS PLAN PURSUANT TO RULE 18f-3
                    UNDER THE INVESTMENT COMPANY ACT OF 1940

         This Multiple Class Plan ("Plan") has been adopted by a majority of the
Board of Trustees of Vanguard Tax-Managed Funds (the "Trust"), including a
majority of the Trustees who are not interested persons of the Trust, on behalf
of the Trust. This Plan pertains to three Funds of the Trust: Vanguard
Tax-Managed Growth and Income Fund, Vanguard Tax-Managed Capital Appreciation
Fund, and Vanguard Tax-Managed Small-Cap Fund (the "Multiple Class Funds").
Provisions of the Plan relating to Vanguard Tax-Managed Small-Cap Fund will take
effect upon the effectiveness of the Fund.

 I.      SHARE CLASSES

         Each of the Multiple Class Funds will offer two classes of shares as
follows:

         A.       VANGUARD TAX-MANAGED GROWTH AND INCOME FUND

                  1.       Vanguard Tax-Managed Growth and Income Fund-Investor
                           Shares (referred to herein as "Class A Shares"); and

                  2.       Vanguard Tax-Managed Growth and Income
                           Fund-Institutional Shares (referred to herein as
                           "Class C Shares").

         B.       VANGUARD TAX-MANAGED CAPITAL APPRECIATION FUND

                  1.       Vanguard Tax-Managed Capital Appreciation
                           Fund-Investor Shares (referred to herein as "Class A
                           Shares"); and

                  2.       Vanguard Tax-Managed Capital Appreciation
                           Fund-Institutional Shares (referred to herein as
                           "Class C Shares").

         C.       VANGUARD TAX-MANAGED SMALL-CAP FUND

                  1.       Vanguard Tax-Managed Small-Cap Fund-Investor Shares
                           (referred to herein as "Class A Shares"); and

                  2.       Vanguard Tax-Managed Small-Cap Fund-Institutional
                           Shares (referred to herein as "Class C Shares").

<PAGE>   2
II.      DISTRIBUTION ARRANGEMENTS

         For each Multiple Class Fund, the distribution arrangements will differ
between Class A Shares and Class C Shares as follows:

         A.       CLASS A SHARES

                  Class A Shares will be available to all investors, but will be
marketed primarily to individual investors and smaller institutional investors.
At present, the minimum initial investment requirement for Class A Shares is
expected to be $3,000 for most accounts and $1,000 for Uniform Gifts/Transfers
to Minors Act accounts.

         B.       CLASS C SHARES

                  Class C Shares will be available only to investors who, due to
the substantial size of their investments, are expected to afford the Funds
certain economies of scale with respect to the servicing of their accounts. It
is expected that most investors eligible for Class C Shares will be
institutional entities, such as foundations, endowments, trusts, bank nominees
and corporations. At present, the minimum initial investment requirement for
Class C Shares is expected to be at least $10 million.

III.     SERVICE ARRANGEMENTS

         Service arrangements will differ between Class A Shares and Class C
Shares of each Multiple Class Fund as follows:

         A.       CLASS A SHARES

                  Class A Shares will be serviced primarily through The Vanguard
Group, Inc.'s ("Vanguard's") Individual Investor Services Group. Due to the
lower minimum initial investment requirement, it is expected that Class A Shares
will be held by more investors than Class C Shares. It is anticipated that the
aggregate amount of account-based services(1) that are provided to Class A
Shares will materially exceed the amount of such services for Class C Shares.

         B.       CLASS C SHARES

                  Class C Shares will be serviced primarily through Vanguard's
Institutional Investor Services Group. Due to the higher minimum initial
investment requirement, it is expected that Class C Shares will be held by fewer
investors than Class A Shares. It is anticipated that the aggregate amount of
account-based services that are provided to Class C Shares will be materially
less than the amount of such services provided to Class A Shares.


- --------
     (1) "Account-based services" for purposes of the Plan are defined as
services provided by Vanguard on a per account basis to the Funds. Such services
include transaction processing, shareholder recordkeeping and the mailing of
shareholder reports, proxy materials and other items.

IV.      EXCHANGES AND CONVERSIONS

         A.       EXCHANGES

                  1.       CLASS A SHARES

                           Class A Shares may be exchanged for Class C Shares of
         the same Multiple Class Fund provided that all purchase eligibility
         requirements for Class C Shares are satisfied by the holder of Class A
         Shares. Class A Shares of each Multiple Class Fund may be exchanged for
         shares of any of the other investment companies for which Vanguard
         provides administrative services ("Vanguard Funds"); provided that (a)
         exchanges are permitted by the Vanguard Fund; (b) the investor meets
         all purchase eligibility requirements then imposed by the Vanguard
         Fund; and (c) any such exchange is permitted by the Investment Company
         Act of 1940, as amended ("1940 Act") and the rules, regulations and
         interpretations thereunder.

                  2.       CLASS C SHARES

                           Class C Shares of one Multiple Class Fund may be
         exchanged for Class A Shares of the same Multiple Class Fund provided
         that all purchase eligibility requirements for Class A shares are
         satisfied by the holder of Class C Shares. Class C Shares of each
         Multiple Class Fund may be exchanged into any Vanguard Fund; provided
         that (a) exchanges are permitted by such Vanguard Fund; (b) the
         investor meets all purchase eligibility requirements then imposed by
         the Vanguard Fund; and (c) any such exchanges are permitted by the 1940
         Act and the rules, regulations and interpretations thereunder.

         B.       CONVERSIONS OF CLASS C SHARES INTO CLASS A SHARES

                  The Trust may convert an investor's Class C Shares into Class
A Shares of the same Multiple Class Fund if such investor's account falls below
the then-applicable minimum initial investment amount for Class C Shares. Any
such conversion will be preceded by written notice to the investor and will be
effected on the basis of the relative net asset values of Class A Shares and
Class C Shares of the applicable Multiple Class Fund without the imposition of
any sales load, fee or other charge.

V.       EXPENSE ALLOCATION BETWEEN CLASSES

         A.       BACKGROUND

                  The Trust is a member of The Vanguard Group of Investment
Companies (the "Group"). Through their jointly-owned subsidiary, Vanguard, the
Trust and the other Vanguard Funds obtain at cost virtually all of their
corporate management, administrative and distribution services. Vanguard also
provides investment advisory services on an at-cost basis to the Trust and
certain other Vanguard Funds. Vanguard was established and operates pursuant to
a Funds' Service Agreement ("Agreement") between itself and the Vanguard Funds,
and pursuant to an exemptive order granted by the U.S. Securities and Exchange
Commission. Vanguard's direct and indirect 
<PAGE>   4
expenses of providing corporate management, administrative and distribution
services to the Vanguard Funds are allocated among the Vanguard Funds in
accordance with methods specified in the Agreement.

         B.       CLASS-SPECIFIC EXPENSES

                  1.       MARKETING AND DISTRIBUTION EXPENSES

                           Expenses associated with Vanguard's marketing and
         distribution activities will be allocated to the Multiple Class Funds
         on behalf of which the expenses were incurred by making such
         allocations to the Multiple Class Funds' Class A Shares and Class C
         Shares as if each such share class were a separate Vanguard Fund under
         the Agreement.

                  2.       EXPENSES FOR ACCOUNT-BASED SERVICES

                           Expenses associated with Vanguard's provision of
         account-based services to the Multiple Class Funds will be allocated
         between Class A Shares and Class C Shares of each Multiple Class Fund
         on the basis of the amount incurred by each such share class as
         follows:

                           (a)      ACCOUNT MAINTENANCE EXPENSES

                                    For each Multiple Class Fund, expenses
                  associated with the maintenance of investor accounts will be
                  proportionately allocated between Class A Shares and Class C
                  Shares based upon a monthly determination of (i) the
                  percentage of total shareholder accounts represented by each
                  class, and (ii) the percentage of total account transactions
                  performed by Vanguard for each class. In allocating account
                  maintenance expenses between the classes, (i) above will be
                  given a 75% weighting and (ii) above will be given a 25%
                  weighting.

                           (b)      LITERATURE PRODUCTION AND MAILING EXPENSES

                                    For each Multiple Class Fund, expenses
                  associated with shareholder reports, proxy materials and other
                  literature will be allocated between Class A Shares and Class
                  C Shares based upon the number of such items produced and
                  mailed for each class of shares.

                  3.       OTHER CLASS SPECIFIC EXPENSES

                           Expenses for the primary benefit of a particular
         share class will be allocated to that share class. Such expenses
         include the following: each class's share of Vanguard's operating
         expenses (not including expenses related to management of the Fund's
         assets allocated under subparagraph (C) below); blue sky fees; and
         legal fees attributable to a particular class.

                  1.       ASSET MANAGEMENT EXPENSES

                           For each Multiple Class Fund, expenses associated
         with management of the Fund's assets (including all advisory, tax
         preparation and custody fees) will be allocated between Class A Shares
         and Class C Shares on the basis of their relative net assets.

                  2.       OTHER FUND EXPENSES

                           For each Multiple Class Fund, any other expenses not
         described above will be allocated between Class A Shares and Class C
         Shares on the basis of their relative net assets.

VI.      ALLOCATION OF INCOME, GAINS AND LOSSES

         For each Multiple Class Fund, income, gains and losses will be
allocated between Class A Shares and Class C Shares on the basis of their
relative net assets. As a result of differences in allocated expenses, it is
expected that the net income of, and dividends payable to, each class of shares
will vary. For each Multiple Class Fund, dividends and distributions paid to
each class of shares will be calculated in the same manner, on the same day, and
at the same time.

VII.     VOTING AND OTHER RIGHTS

         For each Multiple Class Fund, Class A Shares and Class C Shares will
each have: (i) exclusive voting rights on any matter submitted to shareholders
that relates solely to its service or distribution arrangements; and (ii)
separate voting rights on any matter submitted to shareholders in which the
interests of one class differ materially from the interests of the other class;
and (iii) in all other respects the same rights, obligations and privileges as
each other, except as described in this Plan.

VIII.    AMENDMENTS

         All material amendments to this Plan must be approved by a majority of
the Board of Trustees of the Trust, including a majority of the Trustees who are
not interested persons of the Trust.
