INVESTMENT OBJECTIVES AND POLICIES

Vanguard/Windsor Fund (the "Fund") is a diversified mutual fund, a part of
Vanguard/Windsor Funds, Inc., an open-end investment company.

   The Fund seeks to provide long-term growth of capital by investing mainly in
the equity securities of large and medium-size companies whose stocks are
considered to be undervalued by the Fund's adviser and out of favor with
investors. The Fund's secondary objective is to provide some dividend income.

   The Fund is currently closed to new investors. Existing shareholders may
purchase additional Fund shares, but may not invest more than $25,000 each year.

   IT IS IMPORTANT TO NOTE THAT THE FUND'S SHARES ARE NOT GUARANTEED OR INSURED
BY THE FDIC OR ANY OTHER AGENCY OF THE U.S. GOVERNMENT. AS WITH ANY INVESTMENT
IN COMMON STOCKS, WHICH ARE SUBJECT TO WIDE FLUCTUATIONS IN MARKET VALUE, YOU
COULD LOSE MONEY BY INVESTING IN THE FUND.

FEES AND EXPENSES

Vanguard/Windsor Fund is offered on a no-load basis, which means that you pay no
sales commissions or 12b-1 marketing fees. You will, however, incur expenses for
investment advisory, management, administrative, and distribution services,
which are included in the expense ratio.

   
ADDITIONAL INFORMATION ABOUT THE FUND

A Statement of Additional Information (dated February 20, 1998) containing more
information about the Fund is, by reference, part of this prospectus and may be
obtained without charge by writing to Vanguard, calling our Investor Information
Department at 1-800-662-7447, or visiting the Securities and Exchange
Commission's website (www.sec.gov).
    

WHY READING THIS PROSPECTUS IS IMPORTANT

This prospectus explains the objectives, risks, and strategy of Vanguard/Windsor
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 whether the Fund is the right investment for you. We
suggest that you keep it for future reference.

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION NOR HAS THE SECURITIES AND EXCHANGE COMMISSION PASSED UPON
THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY
IS A CRIMINAL OFFENSE.

FUND PROFILE                                               Vanguard/Windsor Fund

WHO SHOULD INVEST (page 4)

- -     Investors seeking a growth and income stock mutual fund as part of a
      balanced and diversified investment program.

- -     Investors seeking growth of their capital over the long term -- at least
      five years.

- -     Investors seeking some dividend income.

WHO SHOULD NOT INVEST

- -     Investors unwilling to accept significant fluctuations in share price.

RISKS OF THE FUND (pages 4-8)

The Fund's total return will fluctuate within a wide range, so an investor could
lose money over short or even extended periods. The Fund is subject to manager
risk (the chance that poor security selection will cause it to lag the stock
market as a whole) and objective risk (the chance that returns from the types of
stocks that the Fund invests in -- attractively priced or "value" stocks -- will
trail returns from the overall stock market). Because the Fund can invest a
portion of its assets in companies based outside the United States, it is
exposed to several risks unique to foreign securities; see page 7 for details.

DIVIDENDS AND CAPITAL GAINS (page 10)

Dividends are paid in June and December. Capital gains, if any, are paid in
December.

IN EVALUATING PAST PERFORMANCE, REMEMBER THAT IT IS NOT INDICATIVE OF FUTURE
PERFORMANCE AND THAT RETURNS FROM STOCKS WERE HIGH DURING THE PERIODS SHOWN
RELATIVE TO LONGER-TERM HISTORICAL AVERAGES. PERFORMANCE FIGURES INCLUDE THE
REINVESTMENT OF ANY DIVIDEND AND CAPITAL GAINS DISTRIBUTIONS. THE RETURNS ARE
NET OF EXPENSES, BUT THEY DO NOT REFLECT INCOME TAXES A TAXABLE INVESTOR WOULD
HAVE INCURRED. NOTE, TOO, THAT BOTH THE RETURN AND PRINCIPAL VALUE OF AN
INVESTMENT WILL FLUCTUATE SO THAT INVESTORS' SHARES, WHEN REDEEMED, MAY BE WORTH
MORE OR LESS THAN THEIR ORIGINAL COST.

                                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 buying, selling, or exchanging shares. These costs can
erode a substantial portion of the gross income or capital appreciation a fund
achieves. Even seemingly small differences in fund expenses can, over time, have
a dramatic impact on a fund's performance.


                                PLAIN TALK ABOUT

                                  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. Vanguard/Windsor Fund's expense ratio in fiscal year 1997 was 0.27%,
or $2.70 per $1,000 of average net assets. The average growth and income equity
fund had expenses in 1997 of l%, or $l per $1,000 of average net assets,
according to Lipper Analytical Services, which reports on the mutual fund
industry.
    

FUND EXPENSES

The examples below are designed to help you understand the various costs you
would bear, directly or indirectly, as an investor in the Fund.

   As noted in this table, you do not pay fees of any kind when you buy, sell,
or exchange shares of the Fund:

Redemption Fees:                                            None
Exchange Fees:                                              None
</TABLE>

   
   The next table illustrates the operating expenses that you would incur as a
shareholder of the Fund. These expenses are deducted from the Fund's income
before it is paid to you. Expenses include investment advisory fees as well as
the costs of administering the Fund, maintaining accounts, providing shareholder
services, and other activities. The expenses shown in the table are based upon
those incurred in the fiscal year ended October 31, 1997.

   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, by illustrating
the hypothetical expenses that you would incur on a $1,000 investment over
various periods. The example assumes that (1) the Fund provides a return of 5% a
year and (2) you redeem your investment at the end of each period.

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

                   HOW TO READ THE FINANCIAL HIGHLIGHTS TABLE

   
The Fund began fiscal 1997 with a net asset value (price) of $16.99 per share.
During the year, the Fund earned $.36 per share from investment income (interest
and dividends) and $3.94 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 $4.30 per share, $1.74 was returned to shareholders in the
form of distributions ($.41 in dividends, $1.33 in capital gains). The earnings
($4.30 per share) less total distributions ($1.74 per share) resulted in a share
price of $19.55 at the end of the fiscal year, an increase of $2.56 per share
(from $16.99 at the beginning of the period to $19.55 at the end of the period).
Assuming that the shareholder had reinvested the distributions in the purchase
of more shares, the total return from the Fund was 27.04% for the year. As of
October 31, 1997, the Fund had $20.7 billion in net assets; an expense ratio of
0.27% ($2.70 per $1,000 of net assets); and net investment income amounting to
1.89% of its average net assets. It sold and replaced securities valued at 61%
of its total net assets.

                                AND GROWTH FUNDS

Value investing and growth investing are two styles employed by stock fund
managers. Value funds generally emphasize companies that, considering their
assets and earnings history, are attractively priced; these companies often pay
regular dividend income to shareholders. Growth funds focus on companies that,
due to their strong earnings and revenue potential, offer above-average
prospects for capital growth, with less emphasis on dividend income. Value and
growth stocks have, in the past, produced similar long-term returns, though each
has periods when it outperforms the other. In general, value funds are
appropriate for investors who want some dividend income and the potential for
capital gains but are less tolerant of share-price fluctuations. Growth funds,
by contrast, appeal to investors who will accept more volatility in hope of a
greater increase in share price or who prefer a higher portion of the fund's
returns to come as capital gains, which may be taxed at lower rates than
dividend income.

                           INVESTING FOR THE LONG TERM

Vanguard/Windsor Fund is intended to be a long-term investment vehicle and is
not designed to provide investors with a means of speculating on short-term
fluctuations in the stock market.

A WORD ABOUT RISK

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

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

THE FUND'S OBJECTIVES

Vanguard/Windsor Fund seeks to provide long-term growth of capital and, as a
secondary objective, some dividend income. These objectives are fundamental,
which means that they cannot be changed unless a majority of shareholders vote
to do so.

[FLAG] BECAUSE OF THE SEVERAL TYPES OF RISK DESCRIBED ON THE FOLLOWING PAGES,
       YOUR INVESTMENT IN THE FUND, AS WITH ANY INVESTMENT IN COMMON STOCKS,
       COULD LOSE MONEY.

   
WHO SHOULD INVEST

Vanguard/Windsor Fund may be suitable for you if:

- -     You wish to add a growth and income mutual fund to your existing holdings,
      which could include other stock -- as well as bond, money market, and
      tax-exempt -- investments.

- -     You want a value-oriented investment that seeks to provide long-term
      growth as well as some dividend income.

      This Fund is not an appropriate investment if you are a market-timer.
Investors who engage in excessive in-and-out trading activity generate
additional costs that are borne by all of the Fund's shareholders. To minimize
such costs, which reduce the ultimate returns achieved by you and other
shareholders, the Fund has adopted the following policies:

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


                                       4
<PAGE>   9
- -     There is a limit on the number of times you can exchange into or out of
      the Fund (see "Redeeming Shares" in the INVESTING WITH VANGUARD section).

- -     The Fund reserves the right to stop offering shares at any time.

INVESTMENT STRATEGY

This section explains how the investment adviser pursues the Fund's objectives
of long-term capital growth and some dividend income. It also explains several
important risks -- market risk, objective risk, manager risk, country risk, and
currency risk -- faced by investors in the Fund. Unlike the Fund's investment
objectives, the advisor's investment strategy is not fundamental and can be
changed by the Fund's Board of Directors without shareholder approval. However,
before making any important change in its strategy, the Fund will give
shareholders 30 days' notice, in writing.

MARKET EXPOSURE

The Fund is a value-oriented growth and income fund that invests mainly in
large- and mid-capitalization common stocks that offer favorable prospects for
capital growth and dividend income. At times, the Fund may also invest in
preferred stock and in securities that are convertible into common stock.

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

      To illustrate the volatility of stock prices, the following table shows
the best, worst, and average total returns (dividend income plus change in
market value) 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
stock market activity. 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, how the gap between the best and worst
returns tends to narrow over the long term.

                             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 the market 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 did not generate the costs.
Therefore, the Fund discourages short-term trading by, among other things,
closely monitoring daily transactions.

                               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. Vanguard
defines large-capitalization, or large-cap, funds as those holding stocks of
companies with a median market value of their outstanding shares exceeding $7.5
billion. Mid-cap funds hold stocks of companies with a median market value
between $1 billion and $7.5 billion. Small-cap funds hold stocks of companies
with a median market value of up to $1 billion. Historically, large-cap funds
have exhibited lower volatility than mid-cap and small-cap funds.

                             PRICE/EARNINGS RATIOS

A widely used measure of common-stock valuation is the price/earnings (P/E)
ratio. The P/E ratio is simply a stock's current price divided by its earnings
per share from the past year (or sometimes its projected earnings for the coming
year). In general, a lower P/E ratio indicates that a stock is out of favor with
investors and is expected to have slow future growth in profits. A higher P/E
ratio indicates that investors expect rapid growth in a company's profits. Keep
in mind, however, that these expectations can sometimes prove incorrect, and
that there is no "ideal" P/E ratio.

                            PORTFOLIO DIVERSIFICATION


   
In general, the more diversified a fund's portfolio of stocks, the less likely
that a specific stock's poor performance will hurt the fund. One measure of a
fund's level of diversification is the percentage of total net assets
represented by its ten largest holdings. The average U.S. equity mutual fund has
about 30% of its assets invested in its ten largest holdings, while some less
diversified mutual funds have 50% or more of their assets invested in the stocks
of just ten companies. 


      The table covers all of the 1-, 5-, 10-, and 20-year periods from 1926
through 1997. For example, while the average return on stocks for all of the
5-year periods was 10.5%, returns for these 5-year periods ranged from a -12.5%
average (from 1928 through 1932), to 23.9% (from 1950 through 1954). These
average returns reflect past performance and should not be regarded as an
indication of future returns from either the stock market as a whole or this
Fund in particular.
    

      Finally, because Vanguard/Windsor Fund does not hold the same securities
held in the S&P 500 Index or any other market index, the performance of the Fund
will not mirror the returns of any particular index.

[FLAG] THE FUND IS SUBJECT TO OBJECTIVE RISK, WHICH IS THE POSSIBILITY THAT
       RETURNS FROM THE TYPE OF STOCKS IN WHICH THE FUND INVESTS -- ATTRACTIVELY
       PRICED OR "VALUE" STOCKS -- WILL TRAIL RETURNS FROM THE OVERALL STOCK
       MARKET. DIFFERENT TYPES OF STOCKS TEND TO GO THROUGH CYCLES OF
       OUTPERFORMANCE AND UNDERPERFORMANCE IN COMPARISON TO COMMON STOCKS IN
       GENERAL. THESE CYCLES HAVE, IN THE PAST, LASTED FOR AS LONG AS SEVERAL
       YEARS.

   
SECURITY SELECTION

Wellington Management Company, LLP (WMC), adviser to the Fund, selects what it
considers to be undervalued securities of large- and mid-capitalization
companies. Undervalued stocks are generally those that are out of favor with
investors and currently trading at prices that, the adviser feels, are below
what the stocks are worth in relation to their earnings. These stocks typically
- -- but not always -- have lower-than-average price/earnings (P/E) ratios and
higher-than-average dividend yields.

      A stock's value is the key element in WMC's selection process. WMC
considers several fundamental factors, including the stock's projected growth
rate, earnings potential, dividend yield, and P/E ratio. WMC then selects the
stock if it has strong prospects for capital appreciation, but is currently
trading at a price that is lower than what is expected of a stock with such
potential. WMC sets a price that it feels more accurately reflects the stock's
overall worth, and when the stock reaches that predetermined price, it will be
sold.

      The Fund's top ten holdings (which amounted to 33% of the Fund's total net
assets) as of October 31, 1997, follow:

 1. Citicorp
 2. AT&T
 3. Rhone-Poulenc SA ADR
 4. Ford Motor Co.
 5. Columbia/HCA Healthcare
 6. Delta Air Lines, Inc.
 7. Aluminum Co. of America

      Keep in mind that, because the makeup of the Fund may change, this listing
is only a "snapshot" at one point in time. Note, too, that the Fund's relatively
low level of diversification means that there is a greater chance that the poor
performance of a single stock could hurt the Fund.
    

      The Fund is run by WMC according to traditional methods of active
investment management, which means securities are bought and sold according to
WMC's judgments about companies and their financial prospects, and about the
stock market and the economy in general.

[FLAG] THE FUND IS SUBJECT TO MANAGER RISK, WHICH IS THE POSSIBILITY THAT WMC
       MAY DO A POOR JOB OF SELECTING STOCKS.

   
PORTFOLIO TURNOVER

Although the Fund generally seeks to invest for the long term, it retains the
right to sell securities regardless of how long they have been held. The Fund's
average turnover rate for the past ten years has been about 33%. (A turnover
rate of 100% would occur, for example, if the Fund sold and replaced securities
valued at 100% of its total net assets within a one-year period.)
    

INVESTMENT POLICIES

Besides investing in undervalued common stocks, the Fund may follow a number of
investment policies to achieve its objectives.

      The Fund may invest as much as 20% of its assets in securities of
companies based outside the United States and may engage in currency
transactions. These securities can be traded in either U.S. or foreign markets.

[FLAG] THE FUND IS SUBJECT TO COUNTRY RISK AND CURRENCY RISK. COUNTRY RISK IS
       THE POSSIBILITY THAT POLITICAL EVENTS (SUCH AS A WAR), FINANCIAL PROBLEMS
       (SUCH AS GOVERNMENT DEFAULT), OR NATURAL DISASTERS (SUCH AS AN
       EARTHQUAKE) WILL WEAKEN A COUNTRY'S ECONOMY AND CAUSE INVESTMENTS IN THAT
       COUNTRY TO LOSE MONEY. CURRENCY RISK IS THE POSSIBILITY THAT A "STRONGER"
       U.S. DOLLAR WILL REDUCE RETURNS FOR AMERICANS INVESTING OVERSEAS.
       GENERALLY, WHEN THE DOLLAR RISES IN VALUE AGAINST A FOREIGN CURRENCY,
       YOUR INVESTMENT IN THAT COUNTRY LOSES VALUE BECAUSE ITS CURRENCY IS WORTH
       FEWER U.S. DOLLARS. ON THE OTHER HAND, A "WEAKER" DOLLAR GENERALLY LEADS
       TO HIGHER RETURNS FOR AMERICANS HOLDING FOREIGN INVESTMENTS.

      The Fund may invest in money market instruments, fixed-income securities,
convertible securities, and other equity securities, such as preferred stock.
The Fund may invest up to 15% of its assets in restricted securities with
limited marketability or other illiquid securities.

                               PORTFOLIO TURNOVER

Before investing in a mutual fund, you should review its portfolio turnover rate
for an indication of the potential effect of transaction costs on 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. Also, funds with high portfolio turnover rates
may be more likely than low-turnover funds to generate capital gains that must
be distributed to shareholders as taxable income. The average turnover rate for
all domestic stock funds is approximately 80%.

                                  THE RISKS OF
                             INTERNATIONAL INVESTING

Because foreign stock markets operate differently from the U.S. market,
Americans investing abroad will encounter risks not typically associated with
U.S. companies. For instance, foreign companies are not subject to the same
accounting, auditing, and financial reporting standards and practices as U.S.
companies; and their stock may not be as liquid as the stock of similar U.S.
companies. In addition, foreign stock exchanges, brokers, and companies
generally have less government supervision and regulation than in the U.S. These
factors, among others, could negatively impact the returns Americans receive
from a foreign investment. For more information, see the Statement of Additional
Information.

                                   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, exotic types of derivatives -- some of which
can carry considerable risks.


                                PLAIN TALK ABOUT

                                  CASH RESERVES

 With mutual funds, holding cash reserves -- or "cash" -- does not mean
 literally that the fund holds a stack of currency. Rather, cash reserves refer
 to short-term, interest-bearing securities that can easily and quickly be
 converted to cash, such as those described in the prospectus glossary. (Most
 mutual funds keep at least a small percentage of assets in cash to accommodate
 shareholder redemptions.) While some funds strive to keep cash levels at a
 minimum and to always remain fully invested in stocks, other funds allow
 investment advisers to hold up to 20% of a fund's assets in cash reserves.


      The Fund may also invest in derivatives.

[FLAG] THE FUND RESERVES THE RIGHT TO INVEST, TO A LIMITED EXTENT, IN STOCK
       FUTURES AND OPTIONS CONTRACTS, WHICH ARE TRADITIONAL TYPES OF 
       DERIVATIVES.

   
      Losses (or gains) involving futures 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 portfolio. The Fund will
not use futures and options for speculative purposes or as leveraged investments
that magnify the gains or losses of an investment. Rather, the Fund will keep
separate cash reserves or other liquid portfolio securities in the amount of the
obligation underlying the futures or options contract. Only a limited percentage
of the Fund's assets -- 5% -- may be applied toward the deposits required on
futures contracts, and the value of all futures contracts in which the Fund
acquires an interest cannot exceed 20% of the Fund's total assets.

      The reasons for which the Fund may 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 by buying futures instead of actual
      stocks.

- -     To add value to the Fund by buying futures instead of actual stocks when
      futures are cheaper.

      The Fund will usually hold only a small percentage of its assets in cash
reserves, although if the investment adviser believes that market conditions
warrant a temporary defensive measure, the Fund may hold cash reserves without
limit. No more than 35% of the Fund's assets may be invested in short-term
fixed-income securities for purposes other than taking a temporary defensive
position.
    

INVESTMENT LIMITATIONS

   
The Fund has adopted limitations on some of its investment policies. Some of
these limitations are that the Fund will not:

- -     Invest more than 25% of its assets in any one industry.

- -     Borrow money, except for temporary or emergency purposes in an amount not
      exceeding 10% of its net assets. Whenever the Fund's outstanding borrowing
      is more than 5% of its assets, it will stop making investments.

With respect to 75% of its assets, the Fund will not:

- -     Invest more than 5% in the securities of any one company.

- -     Buy more than 10% of the outstanding voting securities of any company.

      A complete list of the Fund's investment limitations can be found in the
Statement of Additional Information. These limitations are fundamental and may
be changed only by approval of a majority of the Fund's shareholders.

INVESTMENT PERFORMANCE

Vanguard/Windsor Fund invests primarily in common stocks, so its performance is
closely correlated to the performance of the overall stock market. Historically,
stock market performance, both domestic and foreign, has been characterized by
sharp up-and-down swings in the short term and by more stable growth over the
long term.

The chart does not make any allowances for federal, state, or local income taxes

SHARE PRICE

The Fund's share price, also called its net asset value, or NAV, is calculated
each business day after the close of trading (generally 4 p.m. Eastern time) on
the New York Stock Exchange. The net asset value per share is calculated by
adding up the total assets of the Fund, subtracting all of its liabilities, or
debts, and then dividing by the total number of Fund shares outstanding:

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

      The daily net asset value is useful to you as a shareholder because the
NAV, multiplied by the number of Fund 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.

   The 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 Fund's name, but the most common is WNDSR.

Whenever you see information on a fund's performance, do not consider the

investment in the fund today. The past is an imperfect guide to the future;
history does not repeat itself in neat, predictable patterns.

                                  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 capital gains distribution. Income
dividends come from the dividends that a fund earns from its holdings as well as
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. These 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 in 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 part of your investment will come back to you as a taxable
distribution. 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 would still have only $5,000 (250 shares x $19
= $4,750 in share value, plus 250 shares x $1 = $250 in distributions), but you
would owe tax on the $250 distribution you received, even if you had reinvested
it in more shares. To avoid "buying a dividend," check a fund's distribution
schedule before you invest.


   
DIVIDENDS, CAPITAL GAINS, AND TAXES

Each June and December, the Fund distributes to its shareholders virtually all
of its income from interest and dividends. Any capital gains realized from the
sale of securities are distributed in December. In addition, the Fund may
occasionally be required to make supplemental dividend or capital gains
distributions at other times during the year. You can choose to receive your
distributions of income and capital gains (or of income alone) in cash, or you
can have them automatically invested in more shares of the 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. Each year Vanguard will send you a statement showing the tax status
of all your distributions.

- -     The dividends and short-term capital gains that you receive are taxable to
      you as ordinary dividend income. Any distributions of net long-term
      capital gains by the Fund are taxable to you as long-term capital gains,
      no matter how long you've owned shares in the Fund. Long-term capital
      gains may be taxed at different rates depending on how long the Fund held
      the securities. Although the Fund does 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 the ordinary investment activities of the Fund.
      Consequently, distributions may vary considerably from year to year.
    

- -     If you sell or exchange your shares, any gain or loss you have is a
      taxable event, which 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.

      The tax information in this prospectus is provided as general information
and will not apply to you if you are investing in a tax-deferred account such as
an IRA. You should consult your tax adviser about the tax consequences of an
investment in the Fund.


   
THE FUND AND VANGUARD

Vanguard/Windsor Fund is a member of The Vanguard Group, a family of more than
30 investment companies with more than 95 distinct investment portfolios and
total net assets of more than $320 billion. All 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

costs.

      A list of the Fund's Directors and officers, and their present positions
and principal occupations during the past five years, can be found in the
Statement of Additional Information.


INVESTMENT ADVISER

The Fund employs Wellington Management Company, LLP (WMC), 75 State Street,
Boston, MA 02109, as its investment adviser. WMC manages the Fund subject to the
control of the Directors and officers of the Fund.

      WMC is paid a quarterly advisory fee based on an average of the Fund's
month-end net assets during that quarter:

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

      Beginning April 30, 1999, WMC's basic advisory fee may be adjusted based
on the total return performance of the Fund as compared to that of the Standard
& Poor's 500 Index. Under the fee schedule, WMC's basic fee may be increased or
decreased by as much as 67% for the first $17.5 billion of average net assets
managed during the period and by 90% for average net assets over $17.5 billion.
Until this new schedule goes into effect, WMC's basic fee will follow transition
rules set forth by the Securities and Exchange Commission and described in the
Fund's Statement of Additional Information.

   
      For the fiscal year ended October 31, 1997, the net fee paid by
Vanguard/Windsor Fund to its adviser was $11,681,000, after a decrease of
$11,821,000 based on performance.
    

      The current fee agreement with WMC authorizes it to choose brokers and
dealers to handle the purchase and sale of the Fund's securities, and directs
WMC to get the best available price and most favorable execution from these
brokers with respect to all transactions. At times, WMC may choose brokers who
charge higher commissions in the interest of obtaining better execution of a
transaction. If more than one broker can obtain the best available price and
favorable execution of a transaction, then WMC is authorized to choose a broker
who, in addition to executing the transaction, will provide research services to
WMC or the Fund. However, WMC will not pay higher commissions specifically for
the purpose of obtaining research services. The Fund may direct WMC to use a
particular broker for certain transactions in exchange for commission rebates or
research services provided to the Fund.

      The Board of Directors may, without prior approval from shareholders,
change the terms of the advisory agreement or hire a new

The Vanguard Group, Inc., is the only MUTUAL mutual fund company. It is owned
jointly by the funds it oversees and by the shareholders in those funds. 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 bought the
management company's publicly traded stock. Because of its structure, Vanguard
operates its funds at cost. Instead of distributing profits from operations to a
separate management company, Vanguard returns profits to fund shareholders in
the form of lower operating expenses.

GENERAL INFORMATION

Vanguard/Windsor Fund is one of two Funds of Vanguard/ Windsor Funds, Inc.,
which is organized under the laws of the state of Maryland. The other Fund is
Vanguard/Windsor II (which is open to all investors). The two Funds are combined
under one corporation for administrative purposes, but for investment management
purposes operate like separate companies.

      Shareholders of Vanguard/Windsor Fund have rights and privileges similar
to those enjoyed by other corporate shareholders. For example, shareholders will
not be responsible for any liabilities of the corporation. If any matters are to
be voted on by shareholders (such as a change in a fundamental investment
objective or the election of Directors), each share outstanding at that point
would be entitled to one vote. Annual meetings will not be held by the Fund
except as required by the Investment Company Act of 1940. A meeting will be
scheduled to vote on the removal of a Director if the holders of at least 10% of
the Fund's shares request a meeting in writing.

   make additional investments, but the total amount invested during a calendar
   year may not exceed $25,000.

         The following sections of the prospectus briefly explain the many
   services we offer you as a Vanguard/Windsor Fund shareholder. Booklets
   providing detailed information are available on the services marked with a

   DISTRIBUTION OPTIONS

   You can receive distributions of dividends and/or capital gains in a number
   of ways:
<TABLE>
<S>                                       <C>
   REINVESTMENT                           Dividends and capital gains are automatically reinvested in additional
                                          shares of the Fund unless you request a different distribution method.

   DIVIDENDS IN CASH                      Dividends are paid by check and mailed to your account's address of
                                          record, and capital gains are reinvested in additional shares of the Fund.

   CAPITAL GAINS IN CASH                  Capital gains distributions are paid by check and mailed to your account's
                                          address of record, and dividends are reinvested in additional shares of the Fund.

   DIVIDENDS AND CAPITAL GAINS            Both dividends and capital gains distributions are paid by check and
   IN CASH                                mailed to your account's address of record.
</TABLE>

   To electronically transfer cash dividends and/or capital gains to your bank,
   savings and loan, or credit union account, see Vanguard Dividend Express
   under "Services and Account Features."

   If you have elected to receive dividend and/or capital gains distributions in
   cash, but the Postal Service is unable to make delivery to your address of
   record, your distribution option will be changed to reinvestment. No interest
   will accrue on amounts represented by uncashed distribution checks.
    

   
BUYING SHARES

new investors. Current shareholders may make additional investments, but the
total amount invested during a calendar year may not exceed $25,000.

commissions or 12b-1 marketing fees.

   REDEEMING SHARES

   IMPORTANT TAX NOTE: ANY SALE OR EXCHANGE OF SHARES IN A NONRETIREMENT ACCOUNT
   COULD RESULT IN A TAXABLE GAIN OR A LOSS.

   
   The ability to redeem (that is, sell or exchange) Fund shares by telephone is
   automatically established for your nonretirement account unless you tell us
   in writing that you do not want this option.
    

      To protect your account from unauthorized or fraudulent telephone
   instructions, Vanguard follows specific security procedures. When we receive
   a call requesting an account transaction, we require the caller to provide:

   [CHECK MARK] Fund name.
   [CHECK MARK] 10-digit account number.
   [CHECK MARK] Name and address exactly as registered on that account.
   [CHECK MARK] Social Security or employer identification number as
   registered on that account.

      If you call to sell shares, the sale proceeds will be made payable to you,
   as the registered shareholder, and mailed to your account's address of
   record.

      If we follow reasonable security procedures, neither the Fund nor Vanguard
   will be responsible for the authenticity of transaction instructions received
   by telephone. We believe that these procedures are reasonable and that, if we
   follow them, you bear the risk of any losses resulting from unauthorized or
   fraudulent telephone transactions on your account.

   HOW TO SELL SHARES

   You may withdraw any part of your account, at any time, by selling shares.
   Sale proceeds are normally mailed within two business days after Vanguard
   receives your request. The sale price of your shares will be the Fund's
   next-determined net asset value after Vanguard receives all required
   documents in good order. Good order means that the request includes:

   [CHECK MARK] Fund name and account number.
   [CHECK MARK] Amount of the transaction (in dollars or shares).
   [CHECK MARK] Signatures of all owners exactly as registered on the account.
   [CHECK MARK] Signature guarantees (if required).
   [CHECK MARK] Any supporting legal documentation that may be required.
   [CHECK MARK] Any certificates you are holding for the account.

   
      Sales or exchange requests received after the close of trading on the New
   York Stock Exchange (generally 4 p.m. Eastern time) are processed at the next
   business day's net asset value. No interest will accrue on amounts
   represented by uncashed redemption checks. The Fund will not cancel any trade
   (e.g., purchase, redemption, or exchange) believed to be authentic once the
   trade request has been received in writing or by telephone.
    

      The Fund reserves the right to close any nonretirement or UGMA/UTMA
   account in which the balance falls below the minimum initial investment. The
   Fund will deduct a $10 annual fee in either June or December if your
   nonretirement account balance falls below $2,500 or if your UGMA/UTMA account
   balance falls below $500. The fee is waived if your total Vanguard account
   assets are $50,000 or more.

   
   SOME WRITTEN REQUESTS REQUIRE A SIGNATURE GUARANTEE FROM A BANK, BROKER, OR
   OTHER ACCEPTABLE FINANCIAL INSTITUTION. A NOTARY PUBLIC CANNOT PROVIDE A
   SIGNATURE GUARANTEE.

   HOW TO EXCHANGE SHARES

   
   An exchange is the selling of shares of one Vanguard fund to purchase shares
   of another.

      Although we make every effort to maintain the exchange privilege, Vanguard
   reserves the right to revise or terminate the exchange privilege, limit the
   amount of an exchange, or reject any exchange, at any time, without notice.

      Because excessive exchanges can potentially disrupt the management of the
   Fund and increase transaction costs, Vanguard limits exchange activity to TWO
   SUBSTANTIVE EXCHANGE REDEMPTIONS (at least 30 days apart) from the Fund
   during any 12-month period. "Substantive" means either a dollar amount or a
   series of movements between Vanguard funds that Vanguard determines, in its
   sole discretion, could have a negative impact on the management of the Fund.
    

      Before you exchange into a new Vanguard fund, be sure to read its
   prospectus. For a copy and for answers to questions you might have, call
   Investor Information.

Glossary     Inside Back Cover

A Growth and Income Stock Mutual Fund

INVESTMENT OBJECTIVES AND POLICIES

Vanguard/Windsor Fund (the "Fund") is a diversified mutual fund, a part of
Vanguard/Windsor Funds, Inc., an open-end investment company.

   The Fund seeks to provide long-term growth of capital by investing mainly in
the equity securities of large and medium-size companies whose stocks are
considered to be undervalued by the Fund's adviser and out of favor with
investors. The Fund's secondary objective is to provide some dividend income.

   The Fund is currently closed to new investors. Existing shareholders may
purchase additional Fund shares, but may not invest more than $25,000 each year.

   IT IS IMPORTANT TO NOTE THAT THE FUND'S SHARES ARE NOT GUARANTEED OR INSURED
BY THE FDIC OR ANY OTHER AGENCY OF THE U.S. GOVERNMENT. AS WITH ANY INVESTMENT
IN COMMON STOCKS, WHICH ARE SUBJECT TO WIDE FLUCTUATIONS IN MARKET VALUE, YOU
COULD LOSE MONEY BY INVESTING IN THE FUND.

FEES AND EXPENSES

Vanguard/Windsor Fund is offered on a no-load basis, which means that you pay no
sales commissions or 12b-1 marketing fees. You will, however, incur expenses for
investment advisory, management, administrative, and distribution services,
which are included in the expense ratio.

IMPORTANT NOTE

This prospectus is intended for institutional clients and for participants in
employer-sponsored retirement or savings plans.

   
ADDITIONAL INFORMATION ABOUT THE FUND

A Statement of Additional Information (dated February 20, 1998) containing more
information about the Fund is, by reference, part of this prospectus and may be
obtained without charge by contacting Vanguard (see back cover) or visiting the
Securities and Exchange Commission's website (www.sec.gov).

This prospectus explains the objectives, risks, and strategy of Vanguard/Windsor
Fund. To highlight terms and concepts important to mutual fund investors, we
have provided "Plain Talk" explanations along the way. Reading the prospectus

suggest that you keep it for future reference.

FUND PROFILE                                               Vanguard/Windsor Fund


WHO SHOULD INVEST (page 4)

- -  Investors seeking a growth and income stock mutual fund as part of a balanced
   and diversified investment program.
 
- -  Investors seeking growth of their
   capital over the long term -- at least five years.

- -  Investors seeking some dividend income.

WHO SHOULD NOT INVEST

- -  Investors unwilling to accept significant fluctuations in share price.

RISKS OF THE FUND (pages 4 - 8)

The Fund's total return will fluctuate within a wide range, so an investor could
lose money over short or even extended periods. The Fund is subject to manager
risk (the chance that poor security selection will cause it to lag the stock
market as a whole) and objective risk (the chance that returns from the types of
stock that the Fund invests in -- attractively priced or "value" stocks -- will
trail returns from the overall stock market). Because the Fund can invest a
portion of its assets in companies based outside the United States, it is
exposed to several risks unique to foreign securities; see page 7 for details.

DIVIDENDS AND CAPITAL GAINS (page 10)

Dividends are paid in June and December. Capital gains, if any, are paid in
December. In participant accounts, all distributions are automatically
reinvested.

                             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 buying, selling, or exchanging shares. These costs can
erode a substantial portion of the gross income or capital appreciation a fund
achieves. Even seemingly small differences in fund expenses can, over time, have
a dramatic impact on a fund's performance.
    

                                PLAIN TALK ABOUT

                                  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. Vanguard/Windsor Fund's expense ratio in fiscal year 1997 was 0.27%,
or $2.70 per $1,000 of average net assets. The average growth and income equity
fund had expenses in 1997 of -%, or $- per $1,000 of average net assets,
according to Lipper Analytical Services, which reports on the mutual fund
industry.
    

FUND EXPENSES

The examples below are designed to help you understand the various costs you
would bear, directly or indirectly, as an investor in the Fund.

   As noted in this table, you do not pay fees of any kind when you buy, sell,
or exchange shares of the Fund:

SHAREHOLDER TRANSACTION EXPENSES
Sales Load Imposed on Purchases:                            None
Sales Load Imposed on Reinvested Dividends:                 None
Redemption Fees:                                            None
Exchange Fees:                                              None

   
   The next table illustrates the operating expenses that you would incur as a
shareholder of the Fund. These expenses are deducted from the Fund's income
before it is paid to you. Expenses include investment advisory fees as well as
the costs of administering the Fund, maintaining accounts, providing shareholder
services, and other activities. The expenses shown in the table are based upon
those incurred in the fiscal year ended October 31, 1997.

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

                                PLAIN TALK ABOUT
   
                   HOW TO READ THE FINANCIAL HIGHLIGHTS TABLE

The Fund began fiscal 1997 with a net asset value (price) of $16.99 per share.
During the year, the Fund earned $.36 per share from investment income (interest
and dividends) and $3.94 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 $4.30 per share, $1.74 was returned to shareholders in the
form of distributions ($.41 in dividends, $1.33 in capital gains). The earnings
($4.30 per share) less distributions ($1.74 per share) resulted in a share price
of $19.55 at the end of the fiscal year, an increase of $2.56 per share (from
$16.99 at the beginning of the period to $19.55 at the end of the period).
Assuming that the shareholder had reinvested the distributions in the purchase
of more shares, the total return from the Fund was 27.04% for the year.

   As of October 31, 1997, the Fund had $20.7 billion in net assets; an expense
ratio of 0.27% ($2.70 per $1,000 of net assets); and net investment income
amounting to 1.89% of its average net assets. It sold and replaced securities
valued at 61% of its total net assets.

                                AND GROWTH FUNDS

Value investing and growth investing are two styles employed by stock fund
managers. Value funds generally emphasize companies that, considering their
assets and earnings history, are attractively priced; these companies often
pay regular dividend income to shareholders. Growth funds focus on companies
that, due to their strong earnings and revenue potential, offer above-average
prospects for capital growth, with less emphasis on dividend income. Value and
growth stocks have, in the past, produced similar long-term returns, though each
has periods when it outperforms the other. In general, value funds are
appropriate for investors who want some dividend income and the potential for
capital gains but are less tolerant of share-price fluctuations. Growth funds,
by contrast, appeal to investors who will accept more volatility in hope of a
greater increase in share price or who prefer a higher portion of the Fund's
returns to come as capital gains, which may be taxed at lower rates than
dividend income.

                           INVESTING FOR THE LONG TERM

Vanguard/Windsor Fund is intended to be a long-term investment vehicle and is
not designed to provide investors with a means of speculating on short-term
fluctuations in the stock market.


A WORD ABOUT RISK

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

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

THE FUND'S OBJECTIVES

Vanguard/Windsor Fund seeks to provide long-term growth of capital and, as a
secondary objective, some dividend income. These objectives are fundamental,
which means that they cannot be changed unless a majority of shareholders vote
to do so.

[FLAG]   BECAUSE OF THE SEVERAL TYPES OF RISK DESCRIBED ON THE FOLLOWING PAGES,
         YOUR INVESTMENT IN THE FUND, AS WITH ANY INVESTMENT IN COMMON STOCKS,
         COULD LOSE MONEY.

WHO SHOULD INVEST

Vanguard/Windsor Fund may be suitable for you if:

- -  You wish to add a growth and income mutual fund to your existing holdings,
   which could include other stock -- as well as bond, money market, and
   tax-exempt -- investments.

- -  You want a value-oriented investment that seeks to provide long-term growth,
   as well as some dividend income.

   This Fund is not an appropriate investment if you are a market-timer.
Investors who engage in excessive in-and-out trading activity generate
additional costs that are borne by all the Fund's shareholders. To minimize such
costs, which reduce the ultimate returns achieved by you and other shareholders,
the Fund has adopted the following policies:

- -  The Fund reserves the right to reject any purchase request -- including
   exchanges from other Vanguard funds -- that it regards as disruptive to the
   efficient management of the Fund. 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 or out of the
   Fund. If you own shares of the Fund as an investment option in an
   employer-sponsored retirement or savings



                                       4

   plan, your plan dictates the rules governing exchanges. Contact your plan
   administrator for details.

- -  The Fund reserves the right to stop offering shares at any time.


INVESTMENT STRATEGY

This section explains how the investment adviser pursues the Fund's objectives
of long-term capital growth and some dividend income. It also explains several
important risks -- market risk, objective risk, manager risk, country risk, and
currency risk -- faced by investors in the Fund. Unlike the Fund's investment
objectives, the advisor's investment strategy is not fundamental and can be
changed by the Fund's Board of Directors without shareholder approval. However,
before making any important change in its strategy, the Fund will give
shareholders 30 days' notice, in writing.

MARKET EXPOSURE

The Fund is a value-oriented growth and income fund that invests mainly in
large- and mid-capitalization common stocks that offer favorable prospects for
capital growth and dividend income. At times, the Fund may also invest in
preferred stock and in securities that are convertible into common stock.

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

   To illustrate the volatility of stock prices, the following table shows the
best, worst, and average total returns (dividend income plus change in market
value) 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
stock market activity. 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, how the gap between the best and worst
returns 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. For example, while the average return on stocks for all of the
5-year periods was 10.5%, returns for these 5-year periods ranged from a -12.5%
average (from 1928 through 1932), to 23.9% (from 1950 through 1954). These
average returns reflect past performance and should not be regarded as an
indication of future returns from either the stock market as a whole or this
Fund in particular.

   Finally, because Vanguard/Windsor Fund does not hold the same securities held
in the S&P 500 Index or any other market index, the performance of the Fund will
not mirror the returns of any particular index.

[FLAG]   THE FUND IS SUBJECT TO OBJECTIVE RISK, WHICH IS THE POSSIBILITY THAT
         RETURNS FROM THE TYPE OF STOCKS IN WHICH THE FUND INVESTS --
         ATTRACTIVELY PRICED OR "VALUE" STOCKS -- WILL TRAIL RETURNS FROM THE
         OVERALL STOCK MARKET. DIFFERENT TYPES OF STOCKS TEND TO GO THROUGH
         CYCLES OF OUTPERFORMANCE AND UNDERPERFORMANCE IN COMPARISON TO COMMON
         STOCKS IN GENERAL. THESE CYCLES HAVE, IN THE PAST, LASTED FOR AS LONG
         AS SEVERAL YEARS.
    

                                PLAIN TALK ABOUT

                             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 the market 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 did not generate the costs.
Therefore, the Fund discourages short-term trading by, among other things,
closely monitoring daily transactions.

                              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. Vanguard
defines large-capitalization, or large-cap, funds as those holding stocks of
companies with a median market value of their outstanding shares exceeding $7.5
billion. Mid-cap funds hold stocks of companies with a median market value
between $1 billion and $7.5 billion. Small-cap funds hold stocks of companies
with a median market value of up to $1 billion. Historically, large-cap funds
have exhibited lower volatility than mid-cap and small-cap funds.

                              PRICE/EARNINGS RATIO

A widely used measure of common-stock valuation is the price/earnings (P/E)
ratio. The P/E ratio is simply a stock's current price divided by its earnings
per share from the past year (or sometimes its projected earnings for the coming
year). In general, a lower P/E ratio indicates that a stock is out of favor with
investors and is expected to have slow future growth in profits. A higher P/E
ratio indicates that investors expect rapid growth in a company's profits. Keep
in mind, however, that these expectations can sometimes prove incorrect, and
that there is no "ideal" P/E ratio.

                            PORTFOLIO DIVERSIFICATION

   
In general, the more diversified a fund's portfolio of stocks, the less likely
that a specific stock's poor performance will hurt the fund. One measure of a
fund's level of diversification is the percentage of total net assets
represented by its ten largest holdings. The average U.S. equity mutual fund has
about 30% of its assets invested in its ten largest holdings, while some less
diversified mutual funds have 50% or more of their assets invested in the stocks
of just ten companies.
    

SECURITY SELECTION

Wellington Management Company, LLP (WMC), adviser to the Fund, selects what it
considers to be undervalued securities of large- and mid-capitalization
companies. Undervalued stocks are generally those that are out of favor with
investors and currently trading at prices that, the adviser feels, are below
what the stocks are worth in relation to their earnings. These stocks typically
- -- but not always -- have lower-than-average price/earnings (P/E) ratios and
higher-than-average dividend yields.

   A stock's value is the key element in WMC's selection process. WMC considers
several fundamental factors, including the stock's projected growth rate,
earnings potential, dividend yield, and P/E ratio. WMC then selects the stock if
it has strong prospects for capital appreciation, but is currently trading at a
price that is lower than what is expected of a stock with such potential. WMC
sets a price that it feels more accurately reflects the stock's overall "worth,
and when the stock reaches that predetermined price, it will be sold.

   
   The Fund's top ten holdings (which amounted to 33% of the Fund's total net
assets) as of October 31, 1997, follow:

    1. Citicorp
    2. AT&T
    3. Rhone-Poulenc SA ADR
    4. Ford Motor Co.

   Keep in mind that, because the makeup of the Fund may change, this listing is
only a "snapshot" at one point in time. Note, too, that the Fund's relatively
low level of diversification means that there is a greater chance that the poor
performance of a single stock could hurt the Fund.

   The Fund is run by WMC according to traditional methods of active investment
management, which means securities are bought and sold according to WMC's
judgments about companies and their financial prospects, and about the stock
market and the economy in general.

[FLAG]   THE FUND IS SUBJECT TO MANAGER RISK, WHICH IS THE POSSIBILITY THAT WMC
         MAY DO A POOR JOB OF SELECTING STOCKS.

   
PORTFOLIO TURNOVER

Although the Fund generally seeks to invest for the long term, it retains the
right to sell securities regardless of how long they have been held. The Fund's
average turnover rate for the past ten years has been about 33%. (A turnover
rate of 100% would occur, for example, if the Fund sold and replaced securities
valued at 100% of its total net assets within a one-year period.)
    

INVESTMENT POLICIES

Besides investing in undervalued common stocks, the Fund may follow a number of
investment policies to achieve its objectives.

   The Fund may invest as much as 20% of its assets in securities of companies
based outside the United States and may engage in currency transactions. These
securities can be traded in either U.S. or foreign markets.

[FLAG]   THE FUND IS SUBJECT TO COUNTRY RISK AND CURRENCY RISK. COUNTRY RISK IS
         THE POSSIBILITY THAT POLITICAL EVENTS (SUCH AS A WAR), FINANCIAL
         PROBLEMS (SUCH AS GOVERNMENT DEFAULT), OR NATURAL DISASTERS (SUCH AS AN
         EARTHQUAKE) WILL WEAKEN A COUNTRY'S ECONOMY AND CAUSE INVESTMENTS IN
         THAT COUNTRY TO LOSE MONEY. CURRENCY RISK IS THE POSSIBILITY THAT A
         "STRONGER" U.S. DOLLAR WILL REDUCE RETURNS FOR AMERICANS INVESTING
         OVERSEAS. GENERALLY, WHEN THE DOLLAR RISES IN VALUE AGAINST A FOREIGN
         CURRENCY, YOUR INVESTMENT IN THAT COUNTRY LOSES VALUE BECAUSE ITS
         CURRENCY IS WORTH FEWER U.S. DOLLARS. ON THE OTHER HAND, A "WEAKER"
         DOLLAR GENERALLY LEADS TO HIGHER RETURNS FOR AMERICANS HOLDING FOREIGN
         INVESTMENTS.

   The Fund may invest in money market instruments, fixed-income securities,
convertible securities, and other equity securities such as preferred stock. The
Fund may invest up to 15% of its

                               PORTFOLIO TURNOVER

Before investing in a mutual fund, you should review its portfolio turnover rate
for an indication of the potential effect of transaction costs on 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. The average turnover rate for all domestic stock
funds is approximately 80%.

                                  THE RISKS OF
                             INTERNATIONAL INVESTING

Because foreign stock markets operate differently from the U.S. market,
Americans investing abroad will encounter risks not typically associated with
U.S. companies. For instance, foreign companies are not subject to the same
accounting, auditing, and financial reporting standards and practices as U.S.
companies; and their stock may not be as liquid as the stock of similar U.S.
companies. In addition, foreign stock exchanges, brokers, and companies
generally have less government supervision and regulation than their
counterparts in the United States. These factors, among others, could negatively
impact the returns Americans receive from a foreign investment. For more
information, see the Statement of Additional Information.

                                   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, exotic types of derivatives -- some of which
can carry considerable risks.

                                  CASH RESERVES

With mutual funds, holding cash reserves -- or "cash" -- does not mean literally
that the fund holds a stack of currency. Rather, cash reserves refer to
short-term, interest-bearing securities that can easily and quickly be converted
to cash, such as those described in the prospectus glossary. (Most mutual funds
keep at least a small percentage of assets in cash to accommodate shareholder
redemptions.) While some funds strive to keep cash levels at a minimum and to
always remain fully invested in stocks, other funds allow investment advisers to
hold up to 20% of a fund's assets in cash reserves.

assets in restricted securities with limited marketability or other illiquid
securities. 

The Fund may also invest in derivatives.

[FLAG]   THE FUND RESERVES THE RIGHT TO INVEST, TO A LIMITED EXTENT, IN STOCK
         FUTURES AND OPTIONS CONTRACTS, WHICH ARE TRADITIONAL TYPES OF
         DERIVATIVES.

   
   Losses (or gains) involving futures 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 portfolio. The Fund will not use
futures and options for speculative purposes or as leveraged investments that
magnify the gains or losses of an investment. Rather, the Fund will keep
separate cash reserves or other liquid portfolio securities in the amount of the
obligation underlying the futures or options contract. Only a limited percentage
of the Fund's assets -- 5% -- may be applied toward the deposits required on
futures contracts, and the value of all futures contracts in which the Fund
acquires an interest cannot exceed 20% of the Fund's total assets.

   The reasons for which the 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 by buying futures instead of actual
   stocks.

- -  To add value to the Fund by buying futures instead of actual stocks when
   futures are cheaper.
    

   The Fund will usually hold only a small percentage of its assets in cash
reserves, although if the investment adviser believes that market conditions
warrant a temporary defensive measure, the Fund may hold cash reserves without
limit. No more than 35% of the Fund's assets may be invested in short-term
fixed-income securities for purposes other than taking a temporary defensive
position.


   
INVESTMENT LIMITATIONS

The Fund has adopted limitations on some of its investment policies. Some of
these limitations are that the Fund will not:

- -  Invest more than 25% of its assets in any one industry.

- -  Borrow money, except for temporary or emergency purposes in an amount not
   exceeding 10% of its net assets. Whenever the Fund's outstanding borrowing is
   more than 5% of its assets, it will stop making investments. 

   With respect to 75% of its assets, this Fund will not:

- -  Invest more than 5% in the securities of any one company.

- -  Buy more than 10% of the outstanding voting shares of any company.

INVESTMENT PERFORMANCE

Vanguard/Windsor Fund invests primarily in common stocks, so its performance is
closely correlated to the performance of the overall stock market. Historically,
stock market performance, both domestic and foreign, has been characterized by
sharp up-and-down swings in the short term and by more stable growth over the
long term.

SHARE PRICE

   
The Fund's share price, also called its net asset value, or NAV, is calculated
each business day after the close of trading (generally 4 p.m. Eastern time) on
the New York Stock Exchange. The net asset value per share is calculated by
adding up the total assets of the Fund, subtracting all its liabilities, or
debts, and then dividing by the total number of Fund shares outstanding:

As a shareholder, you are entitled to your share of a fund's income from
interest and dividends, and gains from the sale of investments. You receive such
earnings as either an income dividend or capital gains distribution. Income
dividends come from the dividends that a fund earns from its holdings as well as
interest it receives from 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.

The Vanguard Group, Inc. is the only MUTUAL mutual fund company. It is owned
jointly by the funds it oversees and by the shareholders in those funds.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 bought the
management company's publicly traded stock. Because of its structure, Vanguard
operates its funds at cost. Instead of distributing profits from operations to a
separate management company, Vanguard returns profits to fund shareholders in
the form of lower operating expenses.

your shares back to the Fund that day. 

   
   The 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 Fund's name, but the most common is Wndsr.
    


DIVIDENDS, CAPITAL GAINS, AND TAXES

   
Each June and December, the Fund distributes to its shareholders virtually all
of its income from interest and dividends. Any capital gains realized from the
sale of securities are distributed in December. In addition, the Fund may
occasionally be required to make supplemental dividend or capital gains
distributions at other times during the year.
    

   If you own shares of the Fund as an investment option in an
employer-sponsored retirement or savings plan, these dividend and capital gains
distributions will be reinvested in additional Fund shares and accumulate on a
tax-deferred basis. You will not owe taxes on these distributions until you
begin withdrawals. You should consult your plan administrator, your plan's
Summary Plan Document, or your tax adviser about the tax consequences of an
investment in the Fund and of any plan withdrawals.

   If your Vanguard/Windsor Fund investment is not part of an employer-sponsored
plan, you can receive distributions of income or capital gains in cash, or you
may have them automatically reinvested in more shares of the Fund. Both dividend
and capital gains distributions -- whether received in cash or reinvested in
additional shares -- are subject to federal (and possibly state and local)
income taxes, no matter how long you have held the shares in the Fund. You
should consult your tax adviser about other tax consequences of an investment in
the Fund.

THE FUND AND VANGUARD

   
Vanguard/Windsor Fund is a member of The Vanguard Group, a family of more than
30 investment companies with more than 95 distinct investment portfolios and
total net assets of more than $320 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 marketing fees, each fund pays its
allocated share of The Vanguard Group's costs.

INVESTMENT ADVISER

The Fund employs Wellington Management Company, LLP (WMC), 75 State Street,
Boston, MA 02109, as its investment adviser. WMC manages the Fund subject to the
control of the officers and Directors of the Fund.

   WMC is paid a quarterly advisory fee based on an average of the Fund's
month-end net assets during that quarter:

   Beginning April 30, 1999, WMC's basic advisory fee may be adjusted based on
the total return performance of the Fund as compared to that of the Standard &
Poor's 500 Index. Under the fee schedule, WMC's basic fee may be increased or
decreased by as much as 67% for the first $17.5 billion of average net assets
managed during the period and by 90% for average net assets over $17.5 billion.
Until this new schedule goes into effect, WMC's basic fee will follow transition
rules set forth by the Securities and Exchange Commission and described in the
Fund's Statement of Additional Information.

   
   For the fiscal year ended October 31, 1997, the net fee paid by
Vanguard/Windsor Fund to its adviser was $11,681,000, after a decrease of
$11,821,000 based on performance.
    

   The current fee agreement with WMC authorizes it to choose brokers and
dealers to handle the purchase and sale of the Fund's securities, and directs
WMC to get the best available price and most favorable execution from these
brokers with respect to all transactions. At times, WMC may choose brokers who
charge higher commissions in the interest of obtaining better execution of a
transaction. If more than one broker can obtain the best available price and
favorable execution of a transaction, then WMC is authorized to choose a broker
who, in addition to executing the transaction, will provide research services to
WMC or the Fund. However, WMC will not pay higher commissions specifically for
the purpose of obtaining research services. The Fund may direct WMC to use a
particular broker for certain transactions in exchange for commission rebates or
research services provided to the Fund.

   The Board of Directors may, without prior approval from shareholders, change
the terms of the advisory agreement or hire a new investment adviser as either a
replacement for WMC or as an additional adviser. However, no such change would
be made before giving shareholders 30 days' notice, in writing.

GENERAL INFORMATION

Vanguard/Windsor Fund is one of two Funds of Vanguard/Windsor Funds, Inc.,
which is organized under the laws of the state of Maryland. The other Fund is
Vanguard/Windsor II (which is open to all investors). The two Funds are combined
under one corporation for administrative purposes, but for investment
management purposes operate like separate companies.

   Shareholders of Vanguard/Windsor Fund have rights and privileges similar to
those enjoyed by other corporate shareholders. For example, shareholders will
not be responsible for any liabilities of the corporation. If any matters are
to be voted on by shareholders (such as a change in a fundamental investment
objective or the election of Directors), each share outstanding at that point
would be entitled to one vote. Annual meetings will not be held by the Fund
except as required by the Investment Company Act of 1940. A meeting will be
scheduled to vote on the removal of a Director if the holders of at least 10% of
the Fund's shares request a meeting in writing.

INVESTING WITH VANGUARD

FOR PLAN PARTICIPANTS

Vanguard/Windsor Fund is an investment option in your retirement or savings
plan. Your plan administrator or your employee benefits office can provide you
with detailed information on how to participate in your plan and how to elect
the Fund as an investment option.

- -  If you have any questions about the Fund or Vanguard, including the Fund's
   investment objectives, strategy, or risks, contact Vanguard's Participant
   Services Center, toll-free, at 1-800-523-1188.

- -  If you have questions about your account, contact your plan administrator or
   the organization that provides recordkeeping services for your plan.

INVESTMENT OPTIONS AND ALLOCATIONS

Your plan's specific provisions may allow you to change your investment
selections, the amount of your contributions, or how your contributions are
allocated among the investment choices available to you. Contact your plan
administrator or employee benefits office for more details.

TRANSACTIONS

Contributions, exchanges, or redemptions of the Fund's shares are processed as
soon as they have been received by Vanguard in good order. Good order means that
your request includes complete information on your contribution, exchange, or
redemption, and that Vanguard has received the appropriate assets.
   
EXCHANGES

The exchange privilege (your ability to redeem shares from one fund to purchase
shares of another fund) may be available to you through your plan. Although we
make every effort to maintain the exchange privilege, Vanguard reserves the
right to revise or terminate the exchange privilege, limit the amount of an
exchange, or reject any exchange, at any time, without notice. Because excessive
exchanges can potentially disrupt the management of a Fund and increase its
transaction costs, Vanguard limits exchange activity to TWO SUBSTANTIVE EXCHANGE
REDEMPTIONS (at least 30 days apart) from any Fund during any 12-month period.
"Substantive" means either a dollar amount or a series of movements between
Vanguard funds that Vanguard determines, in its sole discretion, could have a
negative impact on the management of the Fund. In addition, certain investment
options, particularly funds made up of company stock or investment contracts,
may be subject to unique restrictions. Contact your plan administrator for
details on the exchange policies that apply to your plan.

   Before making an exchange, you should consider the following:

- -  Before you exchange to another Vanguard fund available in your plan, you
   should read that fund's prospectus. Contact Vanguard's Participant Services
   Center, toll-free, at 1-800-523-1188 for a copy.

- -  Vanguard can accept exchanges only as permitted by your plan. Your plan
   administrator can explain how frequently exchanges are allowed.
    
FOR OTHER INSTITUTIONAL INVESTORS

AT THIS TIME, SHARES OF VANGUARD/WINDSOR FUND ARE NOT BEING OFFERED OR SOLD TO
NEW INVESTORS. Current shareholders may make additional investments, but the
total amount of purchases during a calendar year may not exceed $25,000.

INVESTING WITH VANGUARD (continued)

TRANSACTIONS

   
Purchases, exchanges, or redemptions of the Fund's shares are processed as soon
as they have been received by Vanguard in good order. Good order means that your
request includes complete information on your purchase, exchange, or redemption,
and that Vanguard has received the appropriate assets. The price of shares
bought, exchanged, or sold will be the Fund's next-determined net asset value
after Vanguard has processed your request, provided your request has been
received before the close of trading on the New York Stock Exchange (generally 4
p.m. Eastern time).
    

   Vanguard must consider the interests of all Fund shareholders and so reserves
   the right to:

- -  Delay or reject any purchase or exchange request that may disrupt the Fund's
   operation or performance.

- -  Revise or terminate the exchange privilege or limit the amount of an
   exchange, at any time, without notice.

- -  Take up to seven days to deliver your redemption proceeds.

- -  Pay redemption proceeds--in whole or in part--through a distribution in kind 
   of readily marketable securities.

you chose answer #3 to a question, that's worth three points. Add up your points
and check below for the type of investor you are. (Note: if you chose answer #1
or #2 to Question C, subtract five points from your total score.)

- -   If you scored between 0 and 25 points, you are considered a conservative

INVESTMENT OBJECTIVES AND POLICIES

Vanguard/Windsor II (the "Fund") is a diversified mutual fund, a part of
Vanguard/Windsor Funds, Inc., an open-end investment company.
        
  The Fund seeks to provide long-term growth of capital by investing mainly in
the equity securities of large and medium-size companies whose stocks are
considered by the Fund's advisers to be undervalued and out of favor with
investors. The Fund's secondary objective is to provide some dividend income.

  IT IS IMPORTANT TO NOTE THAT THE FUND'S SHARES ARE NOT GUARANTEED OR INSURED
BY THE FDIC OR ANY OTHER AGENCY OF THE U.S. GOVERNMENT. AS WITH ANY INVESTMENT
IN COMMON STOCKS, WHICH ARE SUBJECT TO WIDE FLUCTUATIONS IN MARKET VALUE, YOU
COULD LOSE MONEY BY INVESTING IN THE FUND.

FEES AND EXPENSES

Vanguard/Windsor II is offered on a no-load basis, which means that you pay no
sales commissions or 12b-1 marketing fees. You will, however, incur expenses for
investment advisory, management, administrative, and distribution services,
which are included in the Fund's expense ratio.

   
ADDITIONAL INFORMATION ABOUT THE FUND

A Statement of Additional Information (dated February 20, 1998) containing more

obtained without charge by writing to Vanguard, calling our Investor Information
Department at 1-800-662-7447, or visiting the Securities and Exchange

WHY READING THIS PROSPECTUS IS IMPORTANT

This prospectus explains the objectives, risks, and strategy of Vanguard/Windsor
II. 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 whether the Fund is the right investment for you. We suggest
that you keep it for future reference.

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION, NOR HAS THE SECURITIES AND EXCHANGE COMMISSION PASSED UPON

IS A CRIMINAL OFFENSE.

FUND PROFILE                                                VANGUARD/WINDSOR II

WHO SHOULD INVEST (page 4)

- -   Investors seeking a growth and income stock mutual fund as part of a
    balanced and diversified investment program.

- -   Investors seeking growth of capital over the long term--at least five years.

- -   Investors seeking some dividend income.

WHO SHOULD NOT INVEST

- -   Investors unwilling to accept significant fluctuations in share price.

RISKS OF THE FUND (pages 4-8)

The Fund's total return will fluctuate within a wide range, so an investor could
lose money over short or even extended periods. The Fund is subject to manager
risk (the chance that poor security selection will cause it to lag the stock
market as a whole) and objective risk (the chance that returns from the type of
stocks that the Fund invests in--attractively priced or "value" stocks--will
trail returns from the overall stock market). Because the Fund can invest a
portion of its assets in companies based outside the United States, it is
exposed to several risks unique to foreign securities. See page 7 for details.

   
DIVIDENDS AND CAPITAL GAINS (page 10)

Dividends are paid in June and December. Capital gains, if any, are paid in
December.

In evaluating past performance, remember that it is not indicative of future
performance and that returns from stocks were high during the periods shown
relative to longer-term historical averages. Performance figures include the
reinvestment of any dividend and capital gains distributions. The returns are
net of expenses, but they do not reflect income taxes a taxable investor would
have incurred. Note, too, that both the return and principal value of an
investment will fluctuate so that investors' shares, when redeemed, may be worth
more or less than their original cost.

                                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 buying, selling, or exchanging shares. These costs can
erode a substantial portion of the gross income or capital appreciation a fund
achieves. Even seemingly small differences in fund 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. Vanguard/Windsor II's expense ratio in fiscal year 1997 was 0.37%, or
$3.70 per $1,000 of average net assets. The average growth and income equity
fund had expenses in 1997 of -%, or $- per $1,000 of average net assets,
according to Lipper Analytical Services which reports on the mutual fund
industry.

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


   
                                PLAIN TALK ABOUT

                   HOW TO READ THE FINANCIAL HIGHLIGHTS TABLE

The Fund began fiscal 1997 with a net asset value (price) of $24.04 per share.
During the year, the Fund earned $.64 per share from investment income (interest
and dividends) and $6.47 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 $7.11 per share, $1.79 was returned to shareholders in the
form of distributions ($.63 in dividends, $1.16 in capital gains). The earnings
($7.11 per share) less total distributions ($1.79 per share) resulted in a share
price of $29.36 at the end of the fiscal year, an increase of $5.32 per share
(from $24.04 at the beginning of the period to $29.36 at the end of the period).
Assuming that the shareholder had reinvested the distributions in the purchase
of more shares, the total return from the Fund was 31.27% for the year.

  As of October 31, 1997, the Fund had $22.6 billion in net assets; an expense
ratio of 0.37% ($3.70 per $1,000 of net assets); and net investment income
amounting to 2.49% of its average net assets. It sold and replaced securities
valued at 30% of its total net assets.

                          VALUE FUNDS AND GROWTH FUNDS

Value investing and growth investing are two styles employed by stock fund
managers. Value funds generally emphasize companies that, considering their
assets and earnings history, are attractively priced; these companies often pay
regular dividend income to shareholders. Growth funds focus on companies that,
due to their strong earnings and revenue potential, offer above-average
prospects for capital growth, with less emphasis on dividend income. Value and
growth stocks have, in the past, produced similar long-term returns, though each
has periods when it outperforms the other. In general, value funds are
appropriate for investors who want some dividend income and the potential for
capital gains but are less tolerant of share-price fluctuations. Growth funds,
by contrast, appeal to investors who will accept more volatility in hope of a
greater increase in share price or who prefer a higher portion of the Fund's
returns to come as capital gains, which may be taxed at lower rates than
dividend income.

A WORD ABOUT RISK

This prospectus discusses the risks you would face as an investor in
Vanguard/Windsor II. It is important to keep in mind one of the main axioms of
investing: the higher the risk of losing money, the higher the potential reward.
The reverse, also, is generally true: the lower the risk, the lower the
potential reward. However, as you consider an investment in the Fund, you should
also take into account your own tolerance for the daily fluctuations of the
stock market.

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

THE FUND'S OBJECTIVES

Vanguard/Windsor II seeks to provide long-term growth of capital and, as a
secondary objective, some dividend income. These objectives are fundamental,
which means that they cannot be changed unless a majority of shareholders vote
to do so.

[FLAG]  BECAUSE OF THE SEVERAL TYPES OF RISK DESCRIBED ON THE FOLLOWING PAGES,
        YOUR INVESTMENT IN THE FUND, AS WITH ANY INVESTMENT IN COMMON STOCKS,
        COULD LOSE MONEY. 

WHO SHOULD INVEST

Vanguard/Windsor II may be suitable for you if:

- -   You wish to add a growth and income stock mutual fund to your existing
    holdings, which could include other stock--as well as bond, money market,
    and tax-exempt--investments. 

- -   You want a value-oriented investment that seeks to provide long-term growth 
    as well as some dividend income.

  This Fund is not an appropriate investment if you are a market-timer.
Investors who engage in excessive in-and-out trading activity generate
additional costs that are borne by all the Fund's shareholders. To minimize such
costs, which reduce the ultimate returns achieved by you and the other
shareholders, the Fund has adopted the following policies:

- -   The Fund reserves the right to reject any purchase request--including 
    exchanges from other Vanguard funds--that it regards as disruptive to the 
    efficient management of the Fund. 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 or out of the 
    Fund (see "Redeeming Shares" in the INVESTING WITH VANGUARD section).

- -   The Fund reserves the right to stop offering shares at any time.

                          INVESTING FOR THE LONG TERM

Vanguard/Windsor II is intended to be a long-term investment vehicle and is not
designed to provide investors with a means of speculating on short-term
fluctuations in the stock market.

INVESTMENT STRATEGY

This section explains how the investment advisers pursue the Fund's objectives
of long-term capital growth and some dividend income. It also explains three
important risks--market risk, objective risk, and manager risk--faced by
investors in the Fund. Unlike the Fund's investment objectives, the advisers'
investment strategy is not fundamental and can be changed by the Fund's Board of
Directors without shareholder approval. However, before making any important
change in its strategy, the Fund will give shareholders 30 days' notice, in
writing.

MARKET EXPOSURE

The Fund is a value-oriented growth and income fund that invests mainly in
large- and mid-capitalization common stocks that offer favorable prospects for
capital growth and dividend income. At times, the Fund may also invest in
preferred stock.

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

  To illustrate the volatility of stock prices, the following table shows the
best, worst, and average total returns (dividend income plus change in market
value) 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
stock market activity. 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, how the gap between the best and worst
returns tends to lessen over the long term.

    The table covers all of the 1-, 5-, 10-, and 20-year periods from 1926
through 1997. For example, while the average return on stocks for all of the
5-year periods was 10.5%, returns for these 5-year periods ranged from a -12.5%
average (from 1928 through 1932), to 23.9% (from 1950 through 1954). These
average returns reflect past performance of common stocks and should not be
regarded as an indication of future returns from either the stock market as a
whole or this Fund in particular.

                            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 the market 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 did not generate the costs.
Therefore, the Fund discourages short-term trading by, among other things,
closely monitoring daily transactions.

   
                                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.
Vanguard defines large-capitalization, or large-cap, funds as those holding
stocks of companies with a median market value exceeding $7.5 billion. Mid-cap
funds hold stocks of companies with a median market value between $1 billion and
$7.5 billion. Small-cap funds hold stocks of companies with a median market
value of up to $1 billion. Historically, large-cap funds have exhibited lower
volatility than mid-cap and small-cap funds.

                             PRICE/EARNINGS RATIOS

A widely used measure of common-stock valuation is the price/earnings (P/E)
ratio. The P/E ratio is simply a stock's current price divided by its earnings
per share from the past year (or sometimes its projected earnings for the coming
year). In general, a lower P/E ratio indicates that a stock is out of favor with
investors and is expected to have slow future growth in profits. A higher P/E
ratio indicates that investors expect rapid growth in a company's profits. Keep
in mind, however, that these expectations sometimes prove incorrect, and that
there is no "ideal" P/E ratio.

  Finally, because Vanguard/Windsor II does not hold the same securities held in
the S&P 500 Index or any other market index, the performance of the Fund will
not mirror the returns of any particular index.

[FLAG]  THE FUND IS SUBJECT TO OBJECTIVE RISK, WHICH IS THE POSSIBILITY THAT THE
        RETURNS FROM THE TYPES OF STOCKS IN WHICH THE FUND INVESTS--ATTRACTIVELY
        PRICED OR "VALUE" STOCKS--WILL TRAIL RETURNS FROM THE OVERALL STOCK
        MARKET. DIFFERENT TYPES OF STOCKS TEND TO GO THROUGH CYCLES OF
        OUTPERFORMANCE AND UNDERPERFORMANCE IN COMPARISON TO COMMON STOCKS IN
        GENERAL. THESE CYCLES HAVE, IN THE PAST, LASTED FOR AS LONG AS SEVERAL
        YEARS.

SECURITY SELECTION

Vanguard/Windsor II employs four investment advisers, each of whom independently
chooses and maintains a portfolio of common stocks for the Fund.

  Each adviser is responsible for a specific percentage of the Fund's assets.
Before the Fund makes a significant change in an adviser's percentage,
shareholders will receive 30 days' notice, in writing.

  The four investment advisers employ active investment management methods,
which means securities are bought and sold according to the advisers' judgments
about companies and their financial prospects, and about the stock market and
the economy in general.

  While the advisers use different processes to select securities for their
portfolios, all four are committed to investing in large- and mid-cap stocks
that, in their opinion, are undervalued. Undervalued stocks are generally those
that are out of favor with investors and currently trading at prices that, the
adviser feels, are below what the stocks are worth in relation to their
earnings. These stocks typically--but not always--have lower-than-average
price/earnings (P/E) ratios and higher-than-average dividend yields.

   
  Barrow, Hanley, Mewhinney & Strauss, Inc. (BHM&S), which is responsible for
about 73% of the Fund's assets, uses traditional methods of stock
selection--research and analysis--to identify undervalued securities. A security
will be sold when, in BHM&S's opinion, its share price accurately reflects the
security's overall worth. At that point, another undervalued security will be
chosen. No more than 15% of BHM&S's portfolio is devoted to a single industry.

  Like BHM&S, Tukman Capital Management, Inc. (Tukman), which manages about 10%
of the Fund's assets, uses traditional research methods to select undervalued
securities. Tukman typically buys stocks of financially sound companies in
growing business sectors only and holds them for three to five years.

  Equinox Capital Management, Inc. (Equinox), which manages about 10% of the
Fund's assets, uses its own fundamental research and proprietary software to
identify undervalued securities with attractive growth and dividend prospects.
Like BHM&S, it avoids large concentrations in a single industry.

  Vanguard Core Management Group, which is responsible for about 7% of the
Fund's assets, selects stocks from a "universe" of about 550 companies. Vanguard
Core Management Group evaluates the stocks using several fundamental factors,
such as a stock's price in relation to its projected growth rate. All of the
stocks selected are expected, as a group, to outperform the Russell 1000 Value
Index, a benchmark of undervalued large- and mid-cap stocks.

  The balance of Vanguard/Windsor II Fund's assets (about 5%) is held in cash
reserves, also managed by Vanguard. Vanguard may invest the Fund's cash reserves
in stock futures. This strategy is intended to keep the Fund more fully invested
in common stocks while retaining cash on hand to meet liquidity needs. See page
8 for more details on the Fund's policy on futures.

  The top ten holdings (which amounted to 25% of the Fund's total net assets) as
of October 31, 1997, follow:

1. Chase Manhattan Corp.

2. International Business Machines Corp.

PORTFOLIO TURNOVER

Although the Fund generally seeks to invest for the long term, it retains the
right to sell securities regardless of how long they have been held. The Fund's
average turnover rate for the past ten years has been about 27%. (A turnover
rate of 100% would occur, for example, if the Fund sold and replaced securities
valued at 100% of its total net assets within a one-year period.) 
    

INVESTMENT POLICIES

Besides investing in undervalued common stocks, the Fund may follow a
number of investment policies to achieve its objectives.

   
  The Fund may invest as much as 20% of its assets in securities of companies
based outside the United States and may engage in currency transactions. These
securities can be traded in either U.S. or foreign markets.

                           PORTFOLIO DIVERSIFICATION

In general, the more diversified a fund's portfolio of stocks, the less likely
that a specific stock's poor performance will hurt the fund. One measure of a
fund's level of diversification is the percentage of total net assets
represented by its ten largest holdings. The average U.S. equity mutual fund has
about 30% of its assets invested in its ten largest holdings, while some less
diversified mutual funds have 50% or more of their assets invested in the stocks
of just ten companies.

                               PORTFOLIO TURNOVER

   
Before investing in a mutual fund, you should review its portfolio turnover rate
for an indication of the potential effect of transaction costs on 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. Also, funds with high portfolio turnover rates
may be more likely than low-turnover funds to generate capital gains that must
be distributed to shareholders as taxable income. The average turnover rate for
all domestic stock funds is approximately 80%.

                                  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, exotic types of derivatives--some of which can
carry considerable risks.

                                  CASH RESERVES

With mutual funds, holding cash reserves--or "cash"--does not mean literally
that the fund holds a stack of currency. Rather, cash reserves refer to
short-term, interest-bearing securities that can easily and quickly be converted
to cash. (Most mutual funds keep at least a small percentage of assets in cash
to accommodate shareholder redemptions.) While some funds strive to keep cash
levels at a minimum and to always remain fully invested in stocks, other funds
allow investment advisers to hold up to 20% of a fund's assets in cash reserves.

   
[FLAG]  THE FUND IS SUBJECT TO COUNTRY RISK AND CURRENCY RISK. COUNTRY RISK IS
        THE POSSIBILITY THAT POLITICAL EVENTS (SUCH AS A WAR), FINANCIAL
        PROBLEMS (SUCH AS GOVERNMENT DEFAULT), OR NATURAL DISASTERS (SUCH AS AN
        EARTHQUAKE) WILL WEAKEN A COUNTRY'S ECONOMY AND CAUSE INVESTMENTS IN
        THAT COUNTRY TO LOSE MONEY. CURRENCY RISK IS THE POSSIBILITY THAT A
        "STRONGER" U.S. DOLLAR WILL REDUCE RETURNS FOR AMERICANS INVESTING
        OVERSEAS. GENERALLY, WHEN THE DOLLAR RISES IN VALUE AGAINST A FOREIGN
        CURRENCY, YOUR INVESTMENT IN THAT COUNTRY LOSES VALUE BECAUSE ITS
        CURRENCY IS WORTH FEWER U.S. DOLLARS. ON THE OTHER HAND, A "WEAKER"
        DOLLAR GENERALLY LEADS TO HIGHER RETURNS FOR AMERICANS HOLDING FOREIGN
        INVESTMENTS.

  The Fund may invest in money market instruments, fixed-income securities,
convertible securities, and other equity securities such as preferred stock. The
Fund may invest up to 15% of its assets in restricted securities with limited
marketability or other illiquid securities.
    

[FLAG]  THE FUND RESERVES THE RIGHT TO INVEST, TO A LIMITED EXTENT, IN STOCK
        FUTURES AND OPTIONS CONTRACTS, WHICH ARE TRADITIONAL TYPES OF
        DERIVATIVES.
   
  Losses (or gains) involving futures 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 portfolio. The Fund will not use
futures and options for speculative purposes or as leveraged investments that
magnify the gains or losses of an investment. Rather, the Fund will keep
separate cash reserves or other liquid portfolio securities in the amount of the
obligation underlying the futures or options contract. Only a limited percentage
of the Fund's assets--5%--may be applied toward the deposits required on futures
contracts, and the value of all futures contracts in which the Fund acquires an
interest cannot exceed 20% of the Fund's total assets.
      
  The reasons for which the 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 by buying futures instead of actual
    stocks.

- -   To add value to the Fund by buying futures instead of actual stocks when 
    futures are cheaper. 
    
  The Fund will usually hold only a small percentage of its assets in cash
reserves, although if the investment adviser believes that market conditions
warrant a temporary defensive measure, the Fund may hold cash reserves without
limit.

INVESTMENT LIMITATIONS

The Fund has adopted limitations on some of its investment policies. Some of
these limitations are that the Fund will not:

- -    Invest more than 25% of its assets in any one industry.

- -    Borrow money, except for temporary or emergency purposes in an amount not
     exceeding 10% of its net assets. Whenever the Fund's outstanding borrowing
     is more than 5% of its assets, it will stop making investments.

     With respect to 75% of its assets, the Fund will not:

- -    Invest more than 5% in the securities of any one company.

- -    Buy more than 10% of the outstanding voting shares of any company.

  A complete list of the Fund's investment limitations can be found in the
Statement of Additional Information. These limitations are fundamental and may
be changed only by approval of a majority of the Fund's shareholders.

    
INVESTMENT PERFORMANCE

Vanguard/Windsor II invests primarily in common stocks, so its performance is
closely correlated to the performance of the overall stock market. Historically,
stock market performance has been characterized by sharp up-and-down swings in
the short term and by more stable growth over the long term.

   
 AVERAGE ANNUAL TOTAL RETURNS FOR PERIODS ENDED OCTOBER 31, 1997

  The results shown above represent the Fund's "average annual total return"
performance, which assumes that any distributions of capital gains and dividends
were reinvested for the indicated periods. Also included is comparative
information on the unmanaged Standard & Poor's 500 Composite Stock Price Index.
The chart does not make any allowances for federal, state, or local income taxes
that shareholders must pay on a current basis.
    
  In weighing these performance figures, note that the Fund has been in
operation since June 24, 1985. BHM&S has been adviser for the majority of Fund
assets from the Fund's inception. Equinox, Tukman, and Vanguard Core Management
Group were added as advisers on November 1, 1991.

                                PAST PERFORMANCE

Whenever you see information on a fund's performance, do not consider the
figures to be an indication of the performance you could expect by making an
investment in the fund today. The past is an imperfect guide to the future;
history does not repeat itself in neat, predictable patterns.

                                 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 capital gains distribution. Income
dividends come from the dividends that a fund earns from its holdings as well as
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. These 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 in 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 part of your investment will come back to you as a taxable
distribution. 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 would still have only $5,000 (250 shares x $19
= $4,750 in share value, plus 250 shares x $1 = $250 in distributions), but you
would owe tax on the $250 distribution you received, even if you had reinvested
it in more shares. To avoid "buying a dividend," check a fund's distribution
schedule before you invest.

SHARE PRICE
   
The Fund's share price, also called its net asset value, or NAV, is calculated
each business day after the close of trading (generally 4 p.m. Eastern time) on
the New York Stock Exchange. The net asset value per share is calculated by
adding up the total assets of the Fund, subtracting all its liabilities, or
debts, and then dividing by the total number of Fund shares outstanding:

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

  The daily net asset value is useful to you as a shareholder because the NAV,
multiplied by the number of Fund 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.

  The 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 Fund's name, but the most common is WndsrII.
    
   
DIVIDENDS, CAPITAL GAINS, AND TAXES

Each June and December, the Fund distributes to shareholders virtually all of
its income from interest and dividends. Any capital gains realized from the sale
of securities are distributed in December. In addition, the Fund may
occasionally be required to make supplemental dividend or capital gains
distributions at other times during the year.

  You can choose to receive your reinvested distributions of income and capital
gains (or of income alone) in cash, or you can have them automatically
re-invested in more shares of the 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. Each year
Vanguard will send you a statement showing the tax status of all your
distributions.

- -     The dividends and short-term capital gains that you receive are taxable to
      you as ordinary dividend income. Any distributions of net long-term
      capital gains are taxable to you as long-term capital gains, no matter how
      long you've owned shares in the Fund. Long-term capital gains may be taxed
      at different rates, depending on how long the Fund held the securities.
      Although the Fund does 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 the ordinary investment activities of the Fund.
      Consequently, distributions may vary considerably from year to year.

- -     If you sell or exchange your shares, any gain or loss you have is a
      taxable event, which means that you may have a capital gain
    


                                       10
<PAGE>   59
      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. 

  The tax information in this prospectus is provided as general information and
will not apply to you if you are investing in a tax-deferred account such as an
IRA. You should consult your tax adviser about the tax consequences of an
investment in the Fund.
   
THE FUND AND VANGUARD

Vanguard/Windsor II is a member of The Vanguard Group, a family of more than 30
investment companies with more than 95 distinct investment portfolios and total
net assets of more than $320 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 marketing fees, each fund pays its
allocated share of The Vanguard Group's costs.

  A list of the Fund's Directors and officers, and their present positions and
principal occupations during the past five years, can be found in the Statement

INVESTMENT ADVISERS

The Fund employs four investment advisers. Each manages its portion of the
Fund's assets subject to the control of the Directors and officers of the Fund.

                              CORPORATE STRUCTURE

The Vanguard Group, Inc., is the only MUTUAL mutual fund company. It is owned
jointly by the funds it oversees and by the shareholders in those funds. 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 bought the
management company's publicly traded stock. Because of its structure, Vanguard
operates its funds at cost. Instead of distributing profits from operations to a
separate management company, Vanguard returns profits to fund shareholders in
the form of lower operating expenses.

  The current fee agreements with the advisers authorize them to choose brokers
or dealers to handle the purchase and sale of the Fund's securities, and direct
the advisers to get the best available price and most favorable execution from
these brokers with respect to all transactions. At times, the advisers may
choose brokers who charge higher commissions in the interest of obtaining better
execution of a transaction. If more than one broker can obtain the best
available price and favorable execution of a transaction, then the advisers are
authorized to choose a broker who, in addition to executing the transaction,
will provide research services to the advisers or the Fund. However, the
advisers will not pay higher commissions specifically for the purpose of
obtaining research services. The Fund may direct the advisers to use a
particular broker for certain transactions in exchange for commission rebates or
research services provided to the Fund.

  The Board of Directors may, without prior approval from shareholders, change
the terms of the advisory agreements or hire a new investment adviser as either
a replacement adviser or as an additional adviser. However, no such change would
be made before giving shareholders 30 days' notice, in writing. 

GENERAL INFORMATION

Vanguard/Windsor II is one of two Funds of Vanguard/Windsor Funds, Inc., which
is organized under the laws of the state of Maryland. The other Fund is
Vanguard/Windsor Fund (which is not open to new investors). The two Funds are
combined under one corporation for administrative purposes, but for investment
management purposes operate like separate companies.

  Shareholders of Vanguard/Windsor II have rights and privileges similar to
those enjoyed by other corporate shareholders. For example, shareholders will
not be responsible for any liabilities of the corporation. If any matters are to
be voted on by shareholders (such as a change in a fundamental investment
objective or the election of Directors), each share outstanding at that point
would be entitled to one vote. Annual meetings will not be held by the Fund
except as required by the Investment Company Act of 1940. A meeting will be
scheduled to vote on the removal of a Director if the holders of at least 10% of
the Fund's shares request a meeting in writing.

DISTRIBUTION OPTIONS 

You can receive distributions of dividends and/or capital gains in a number of
ways:

REINVESTMENT                        Dividends and capital gains are        
                                    automatically reinvested in additional 
                                    shares of the Fund unless you request a
                                    different distribution method.         
                                    
DIVIDENDS IN CASH                   Dividends are paid by check and mailed to 
                                    your account's address of record, and     
                                    capital gains are reinvested in additional
                                    shares of the Fund.                       
                                    
   
CAPITAL GAINS IN CASH               Capital gains distributions are paid by
                                    check and mailed to your account's 
                                    address of record, and dividends are re-
                                    invested in additional shares of the fund.

savings and loan, or credit union account, see Vanguard Dividend Express under
"Services and Account Features."

cash, but the Postal Service is unable to make delivery to your address of
record, your distribution option will be changed to reinvestment. No interest
will accrue on amounts represented by uncashed distribution checks.
    

BUYING SHARES

receives your request, provided we receive your request before the close of
trading on the New York Stock Exchange (generally 4 p.m. Eastern time). The Fund
is offered on a no-load basis, meaning that you do not pay sales commissions or
12b-1 marketing fees.

IMPORTANT TAX NOTE: Any sale or exchange of shares in a nonretirement account
could result in a taxable gain or loss.

   
The ability to redeem (that is, sell or exchange) Fund shares by telephone is
automatically established for your nonretirement account unless you tell us in
writing that you do not want this option.

   To protect your nonretirement account from unauthorized or fraudulent
telephone instructions, Vanguard follows specific security procedures. When we
receive a call requesting an account transaction, we require the caller to
provide:

  [check mark]       Fund name.

  [check mark]       10-digit account number.

  [check mark]       Name and address exactly as registered on that account.

  [check mark]       Social Security or employer identification number as 
                     registered on that account.
    

   If you call to sell shares, the sale proceeds will be made payable to you, as
the registered shareholder, and mailed to your account's address of record.

   If we follow reasonable security procedures, neither the Fund nor Vanguard
will be responsible for the authenticity of transaction instructions received by
telephone. We believe that these procedures are reasonable and that, if we
follow them, you bear the risk of any losses resulting from unauthorized or
fraudulent telephone transactions on your account.

HOW TO SELL SHARES

You may withdraw any part of your account, at any time, by selling shares. Sale
proceeds are normally mailed within two business days after Vanguard receives
your request. The sale price of your shares will be the Fund's next-determined
net asset value after Vanguard receives all required documents in good order.

Good order means that the request includes:

    [check mark]    Fund name and account number.

    [check mark]    Amount of the transaction (in dollars or shares).

    [check mark]    Signatures of all owners exactly as registered on the
                    account.

    [check mark]    Signature guarantees (if required).

    [check mark]    Any supporting legal documentation that may be required.

    [check mark]    Any certificates you are holding for the account.

   
   Sales or exchange requests received after the close of trading on the New
York Stock Exchange (generally 4 p.m. Eastern time) are processed at the next
business day's net asset value. No interest will accrue on amounts represented
by uncashed redemption checks. The Fund will

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

   The Fund reserves the right to close any nonretirement or UGMA/UTMA account
in which the balance falls below the minimum initial investment. The Fund will
deduct a $10 annual fee in either June or December if your nonretirement account
balance falls below $2,500 or if your UGMA/UTMA account balance falls below
$500. The fee is waived if your total Vanguard account assets are $50,000 or
more.
    

Some written requests require a signature guarantee from a bank, broker, or
other acceptable financial institution. A notary public cannot provide a
signature guarantee.

   
HOW TO EXCHANGE SHARES

An exchange is the selling of shares of one Vanguard fund to purchase shares of
another.

   Although we make every effort to maintain the exchange privilege, Vanguard
reserves the right to revise or terminate the exchange privilege, limit the
amount of an exchange, or reject any exchange, at any time, without notice.

   Because excessive exchanges can potentially disrupt the management of the
Fund and increase transaction costs, Vanguard limits exchange activity to TWO
SUBSTANTIVE EXCHANGE REDEMPTIONS (at least 30 days apart) from the Fund during
any 12-month period. "Substantive" means either a dollar amount or a series of
movements between Vanguard funds that Vanguard determines, in its sole
discretion, could have a negative impact on the management of the Fund.
    

   Before you exchange into a new Vanguard fund, be sure to read its prospectus.

                                 ABOUT THE QUIZ

Knowing your risk tolerance is important when you are making an investment
decision. To give you a general idea of your comfort level with investing,
circle the response that most closely matches your personal situation. Keep in
mind, though, that there is no "foolproof" way to gauge your risk tolerance.
Scoring for the quiz is below.

                              HOW TO SCORE THE QUIZ

Use the number of your answer as the number of points scored. For instance, if
you chose answer #3 to a question, that's worth three points. Add up your points
and check below for the type of investor you are. (Note: If you chose answer #1
or #2 to Question C, subtract five points from your total score.)

- -   If you scored between 0 and 25 points, you are considered a conservative
    investor.

- -   If you scored between 26 and 32 points, you are considered a moderate
    investor.

- -   If you scored between 33 and 35 points, you are considered an aggressive
    investor.

AN INVESTMENT PRIMER

Whether you are investing for the short or long term, keep these three points in
mind:

1. INVEST IN ALL THREE OF THE MAJOR ASSET CLASSES.

Most people use a combination of . . .

- -  Stocks, which are considered the "riskiest" of the three asset classes. Day
   to day, or even year to year, stocks tend to have wide price swings. Despite
   this potential for significant price fluctuation, however, stocks have
   historically offered higher returns than the other major asset classes over
   longer periods.

- -  Bonds, which are chiefly influenced by changes in interest rates. When
   interest rates climb, bond prices drop; when interest rates fall, bond prices
   rise.

- -  Cash reserves, which offer more share-price (or capital) stability than
   stocks or bonds--but also generate lower returns. Some examples are Treasury
   bills and money market funds.

2. REMEMBER THAT SAFETY HAS A PRICE.

Many people want a "no-risk" investment. Remember, though, that the more safety
you seek, the less potential reward you can expect--and the less you can expect
in returns after inflation. Inflation affects not only the price you pay for
goods and services; it also eats away at your investment returns over time. What
is left is known as your "real" return--the actual return you receive after you
factor in inflation (see the chart at left).

3. CHANCES ARE GOOD THAT YOU CAN AFFORD TO TAKE MORE RISK.

As the chart shows, inflation cuts into the returns of all three asset classes.
However, stocks and bonds have had an easier time of outpacing inflation over
time--which means that, to beat inflation, you may need to invest more
aggressively.

   Don't be put off by potential downswings in the value of your investment,
especially if you are investing for long periods. Time acts as a shock absorber,
letting you ride out the short-term bumps that investments often provide. The
longer you hold an investment, the more likely it is that you will earn a
positive return.

                                PLAIN TALK ABOUT
                         INFLATION AND YOUR INVESTMENTS

No matter how you invest your money, inflation--the rising cost of living--is a
constant threat to your investment returns. The chart below shows how stocks,
bonds, and cash reserves have fared against inflation over time.

Glossary     Inside Back Cover

A Growth and Income Stock Mutual Fund

INVESTMENT OBJECTIVES AND POLICIES
Vanguard/Windsor II (the "Fund") is a diversified mutual fund, a part of
Vanguard/Windsor Funds, Inc., an open-end investment company.

   The Fund seeks to provide long-term growth of capital by investing mainly 
in the equity securities of large and medium-size companies whose stocks are
considered to be undervalued by the Fund's advisers and out of favor with
investors. The Fund's secondary objective is to provide some dividend income.

   IT IS IMPORTANT TO NOTE THAT THE FUND'S SHARES ARE NOT GUARANTEED OR INSURED
BY THE FDIC OR ANY OTHER AGENCY OF THE U.S. GOVERNMENT. AS WITH ANY INVESTMENT
IN COMMON STOCKS, WHICH ARE SUBJECT TO WIDE FLUCTUATIONS IN MARKET VALUE, YOU
COULD LOSE MONEY BY INVESTING IN THE FUND.

FEES AND EXPENSES

Vanguard/Windsor II is offered on a no-load basis, which means that you pay no
sales commissions or 12b-1 marketing fees. You will, however, incur expenses for
investment advisory, management, administrative, and distribution services,
which are included in the Fund's expense ratio.

IMPORTANT NOTE

This prospectus is intended for institutional clients and for participants in
employer-sponsored retirement or savings plans. Another version--for individuals
who would like to open a personal account--can be obtained by calling Vanguard
at 1-800-662-7447.
   
ADDITIONAL INFORMATION ABOUT THE FUND

A Statement of Additional Information (dated February 20, 1998) containing more
information about the Fund is, by reference, part of this prospectus and may be
obtained without charge by contacting Vanguard (see back cover) or visiting the
Securities and Exchange Commission's website (www.sec.gov).

WHY READING THIS PROSPECTUS IS IMPORTANT

This prospectus explains the objectives, risks, and strategy of Vanguard/Windsor
II. 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 whether the Fund is the right investment for you. We suggest
that you keep it for future reference.


THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION, NOR HAS THE SECURITIES AND EXCHANGE COMMISSION PASSED UPON

FUND PROFILE                                                Vanguard/Windsor II

WHO SHOULD INVEST (page 4)

- -  Investors seeking a growth and income stock mutual fund as part of a balanced
   and diversified investment program.

- -  Investors seeking growth of their capital over the long term--at least five 
   years.

- -  Investors seeking some dividend income.

WHO SHOULD NOT INVEST

- -  Investors unwilling to accept significant fluctuations in share price.

RISKS OF THE FUND (pages 4-8)
The Fund's total return will fluctuate within a wide range, so an investor could
lose money over short or even extended periods. The Fund is subject to manager
risk (the chance that poor security selection will cause it to lag the stock
market as a whole) and objective risk (the chance that returns from the type of
stocks that the Fund invests in--attractively priced or "value" stocks-- will
trail returns from the overall stock market). Because the Fund can invest a
portion of its assets in companies based outside the United States, it is
exposed to several risks unique to foreign securities; see page 8 for details.

DIVIDENDS AND CAPITAL GAINS (page 10)
Dividends are paid in June and December. Capital gains, if any, are paid in
December. In participant accounts, all distributions are automatically
reinvested.

In evaluating past performance, remember that it is not indicative of future
performance and that returns from stocks were high during the periods shown
relative to longer-term historical averages. Performance figures include the
reinvestment of any dividend and capital gains distributions. The returns are
net of expenses, but they do not reflect income taxes a taxable investor would
have incurred. Note, too, that both the return and principal value of an
investment will fluctuate so that investors' shares, when redeemed, may be worth
more or less than their original cost.

                                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 buying, selling, or exchanging shares. These costs can
erode a substantial portion of the gross income or capital appreciation a fund
achieves. Even seemingly small differences in fund expenses can, over time, have
a dramatic impact on a fund's performance.


                                PLAIN TALK ABOUT
                                  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. Vanguard/Windsor II's expense ratio in fiscal year 1997 was 0.37%, or
$3.70 per $1,000 of average net assets. The average growth and income equity
fund had expenses in 1997 of   %, or $    per $1,000 of average net assets,
according to Lipper Analytical Services, which reports on the mutual fund
industry.
    

FUND EXPENSES

The examples below are designed to help you understand the various costs you
would bear, directly or indirectly, as an investor in the Fund.

  As noted in this table, you do not pay fees of any kind when you buy, sell,
or exchange shares of the Fund:

SHAREHOLDER TRANSACTION EXPENSES
Sales Load Imposed on Purchases:                            None
Sales Load Imposed on Reinvested Dividends:                 None
Redemption Fees:                                            None
Exchange Fees:                                              None

   
  The next table illustrates the operating expenses that you would incur as a
shareholder of the Fund. These expenses are deducted from the Fund's income
before it is paid to you. Expenses include investment advisory fees as well as
the costs of administering the Fund, maintaining accounts, providing shareholder
services, and other activities. The expenses shown in the table are based upon
those incurred in the fiscal year ended October 31, 1997.

ANNUAL FUND OPERATING EXPENSES
Management and Administrative Expenses:                    0.19%
Investment Advisory Expenses:                              0.15%
12b-1 Marketing Fees:                                       None
Other Expenses
   Marketing and Distribution Costs:                 0.02%
   Miscellaneous Expenses (e.g., Taxes, Auditing):   0.01%
                                                     -----
Total Other Expenses:                                      0.03%
                                                           ----
   TOTAL OPERATING EXPENSES (EXPENSE RATIO):               0.37%
                                                           =====

   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, by illustrating
the hypothetical expenses that you would incur on a $1,000 investment over
various periods. The example assumes that (1) the Fund provides a return of 5% a
year and (2) you redeem your investment at the end of each period.

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

                                HIGHLIGHTS TABLE

   
The Fund began fiscal 1997 with a net asset value (price) of $24.04 per share.
During the year, the Fund earned $.64 per share from investment income (interest
and dividends) and $6.47 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 $7.11 per share, $1.79 was returned to shareholders in the
form of distributions ($.63 in dividends, $1.16 in capital gains). The earnings
($7.11 per share) less total distributions ($1.79 per share) resulted in a share
price of $29.36 at the end of the fiscal year, an increase of $5.32 per share
(from $24.04 at the beginning of the period to $29.36 at the end of the period).
Assuming that the shareholder had reinvested the distributions in the purchase
of more shares, the total return from the Fund was 31.27% for the year.

   As of October 31, 1997, the Fund had $22.6 billion in net assets; an expense
ratio of 0.37% ($3.70 per $1,000 of net assets); and net investment income
amounting to 2.49% of its average net assets. It sold and replaced securities
valued at 30% of its total net assets.

                                  GROWTH FUNDS

Value investing and growth investing are two styles employed by stock fund
managers. Value funds generally emphasize companies that, considering their
assets and earnings history, are attractively priced; these companies often pay
regular dividend income to shareholders. Growth funds focus on companies that,
due to their strong earnings and revenue potential, offer above-average
prospects for capital growth, with less emphasis on dividend income. Value and
growth stocks have, in the past, produced similar long-term returns, though each
has periods when it outperforms the other. In general, value funds are
appropriate for investors who want some dividend income and the potential for
capital gains but are less tolerant of share-price fluctuations. Growth funds,
by contrast, appeal to investors who will accept more volatility in hope of a
greater increase in share price, or who prefer a higher portion of the Fund's
returns to come as capital gains, which may be taxed at lower rates than
dividend income.

                                PLAIN TALK ABOUT
                           INVESTING FOR THE LONG TERM

Vanguard/Windsor II is intended to be a long-term investment vehicle and is not
designed to provide investors with a means of speculating on short-term
fluctuations in the stock market.

A WORD ABOUT RISK

   This prospectus discusses the risks you would face as an investor in
Vanguard/Windsor II. It is important to keep in mind one of the main axioms of
investing: The higher the risk of losing money, the higher the potential reward.
The reverse, also, is generally true: The lower the risk, the lower the
potential reward. However, as you consider an investment in the Fund, you should
also take into account your own tolerance for the daily fluctuations of the
stock market.
   Look for this "warning flag" symbol [flag symbol] throughout the prospectus.
It is used to mark detailed information about each type of risk that you, as a
shareholder of the Fund, would confront.

THE FUND'S OBJECTIVES

Vanguard/Windsor II seeks to provide long-term growth of capital and, as a
secondary objective, some dividend income. These objectives are fundamental,
which means that they cannot be changed unless a majority of shareholders vote
to do so.

     [FLAG]    BECAUSE OF THE SEVERAL TYPES OF RISK DESCRIBED ON THE FOLLOWING
               PAGES, YOUR INVESTMENT IN THE FUND, AS WITH ANY INVESTMENT IN
               COMMON STOCKS, COULD LOSE MONEY.


WHO SHOULD INVEST

Vanguard/Windsor II may be suitable for you if:
- -  You wish to add a growth and income stock mutual fund to your existing
   holdings, which could include other stock--as well as bond, money market, and
   tax-exempt--investments.
- -  You want a value-oriented investment that seeks to provide long-term growth
   as well as some dividend income.
   This Fund is not an appropriate investment if you are a market-timer.
Investors who engage in excessive in-and-out trading activity generate
additional costs that are borne by all the Fund's shareholders. To minimize such
costs, which reduce the ultimate returns achieved by you and other shareholders,
the Fund has adopted the following policies: 
- -  The Fund reserves the right to reject any purchase request--including
   exchanges from other Vanguard funds--that it regards as disruptive to the
   efficient management of the Fund. 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 or out of the
   Fund. If you own Fund shares as an investment 


                                       4
<PAGE>   81
   option in an employer-sponsored retirement or savings plan, your plan
   dictates the rules governing exchanges. Contact your plan administrator for
   details.

- -  The Fund reserves the right to stop offering shares at any time.


INVESTMENT STRATEGY

This section explains how the investment advisers pursue the Fund's objectives
of long-term capital growth and some dividend income. It also explains three
important risks--market risk, objective risk, and manager risk--faced by
investors in the Fund. Unlike the Fund's investment objectives, the advisers'
investment strategy is not fundamental and can be changed by the Fund's Board of
Directors without shareholder approval. However, before making any important
change in its strategy, the Fund will give shareholders 30 days' notice, in
writing.

MARKET EXPOSURE
The Fund is a value-oriented growth and income fund that invests mainly in
large- and mid-capitalization common stocks that offer favorable prospects for
capital growth and dividend income. At times, the Fund may also invest in
preferred stocks.

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

   To illustrate the volatility of stock prices, the following table shows the
best, worst, and average total returns (dividend income plus change in market
value) 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
stock market activity. 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, how the gap between the best and worst
returns tends to lessen over the long term.

                             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 the market 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 did not generate the costs.
Therefore, the Fund discourages short-term trading by, among other things,
closely monitoring daily transactions.

                               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.
Vanguard defines large-capitalization, or large-cap, funds as those holding
stocks of companies with a median market value exceeding $7.5 billion. Mid-cap
funds hold stocks of companies with a median market value between $1 billion and
$7.5 billion. Small-cap funds hold stocks of companies with a median market
value of up to $1 billion. Historically, large-cap funds have exhibited lower
volatility than mid-cap and small-cap funds.

                              PRICE/EARNINGS RATIOS
A widely used measure of common-stock valuation is the price/earnings (P/E)
ratio. The P/E ratio is simply a stock's current price divided by its earnings
per share from the past year (or sometimes its projected earnings for the coming
year). In general, a lower P/E ratio indicates that a stock is out of favor with
investors and is expected to have slow future growth in profits. A higher P/E
ratio indicates that investors expect rapid growth in a company's profits. Keep
in mind, however, that these expectations sometimes prove incorrect, and that
there is no "ideal" P/E ratio.

ranged from a -12.5% average (from 1928 through 1932), to 23.9% (from 1950
through 1954). These average returns reflect past performance of common stocks
and should not be regarded as an indication of future returns from either the
stock market as a whole or this Fund in particular. 
   Finally, because Vanguard/Windsor II Fund does not hold the same securities
held in the S&P 500 Index or any other market index, the performance of the Fund
will not mirror the returns of any particular index.

[FLAG] THE FUND IS SUBJECT TO OBJECTIVE RISK, WHICH IS THE POSSIBILITY THAT THE
       RETURNS FROM THE TYPES OF STOCKS IN WHICH THE FUND INVESTS--ATTRACTIVELY
       PRICED OR "VALUE" STOCKS--WILL TRAIL RETURNS FROM THE OVERALL STOCK
       MARKET. DIFFERENT TYPES OF STOCKS TEND TO GO THROUGH CYCLES OF
       OUTPERFORMANCE AND UNDERPERFORMANCE IN COMPARISON TO COMMON STOCKS IN
       GENERAL. THESE CYCLES HAVE, IN THE PAST, LASTED FOR AS LONG AS SEVERAL
       YEARS.

   
SECURITY SELECTION
Vanguard/Windsor II employs four investment advisers, each of whom independently
chooses and maintains a portfolio of common stocks for the Fund.
   Each adviser is responsible for a specific percentage of the Fund's assets.
Before the Fund makes a significant change in an adviser's percentage,
shareholders will receive 30 days' notice, in writing.
   The four investment advisers employ active investment management methods,
which means securities are bought and sold according to the advisers' judgments
about companies and their financial prospects, and about the stock market and
the economy in general.
   While the advisers use different processes to select securities for their
portfolios, all four are committed to investing in large- and mid-cap stocks
that, in their opinion, are undervalued. Undervalued stocks are generally those
that are out of favor with investors and currently trading at prices that, the
adviser feels, are below what the stocks are worth in relation to their
earnings. These stocks typically--but not always--have lower-than-average
price/earnings (P/E) ratios and higher-than-average dividend yields.
   Barrow, Hanley, Mewhinney & Strauss, Inc. (BHM&S), which is responsible for
about 73% of the Fund's assets, uses traditional methods of stock
selection--research and analysis--to identify undervalued securities. A security
will be sold when, in BHM&S's opinion, its share price accurately reflects the
security's overall worth. At that point, another undervalued security will be
chosen. No more than 15% of BHM&S's portfolio is devoted to a single industry.
   Like BHM&S, Tukman Capital Management, Inc. (Tukman), which manages about 10%
of the Fund's assets, uses traditional research methods to select undervalued
securities. Tukman typically buys stocks of financially sound companies in
growing business sectors only and holds them for three to five years.
    



                                       6
<PAGE>   83
   
   Equinox Capital Management, Inc. (Equinox), which manages about 10% of the
Fund's assets, uses its own fundamental research and proprietary software to
identify undervalued securities with attractive growth and dividend prospects.
Like BHM&S, it avoids large concentrations in a single industry.
   Vanguard Core Management Group, which is responsible for about 7% of the
Fund's assets, selects stocks from a "universe" of about 550 companies. Vanguard
Core Management Group evaluates the stocks using several fundamental factors,
such as a stock's price in relation to its projected growth rate. All of the
stocks selected are expected, as a group, to outperform the Russell 1000 Value
Index, a benchmark of undervalued large- and mid-cap stocks.
   The balance of Vanguard/Windsor II Fund's assets (about 5%) is held in cash
reserves, also managed by Vanguard. Vanguard may invest the Fund's cash reserves
in stock futures. This strategy is intened to keep the Fund more fully invested
in common stocks while retaining cash on hand to meed liquidity needs. See page
8 for more details on the Fund's policy on futures.
   The top ten holdings (which amounted to 25% of the Fund's total net assets)
as of October 31, 1997, follow:

    1.  Chase Manhattan Corp.
    2.  International Business Machines Corp.
    3.  Ford Motor Co.
    4.  Exxon Corp.
    5.  GTE Corp.
    6.  Schlumberger Ltd.
    7.  Sears, Roebuck & Co.
    8.  SBC Communications Inc.
    9.  Allstate Corp.
   10.  Travelers Group Inc.

   Keep in mind that, because the makeup of the Fund may change, this listing is
only a "snapshot" at one point in time.

     [FLAG]    THE FUND IS SUBJECT TO MANAGER RISK, WHICH IS THE POSSIBILITY
               THAT ONE OR MORE OF THE FUND'S ADVISERS MAY DO A POOR JOB OF
               SELECTING STOCKS.
    

PORTFOLIO TURNOVER

   
Although the Fund generally seeks to invest for the long term, it retains the
right to sell securities regardless of how long they have been held. The Fund's
average turnover rate for the past ten years has been about 27%. (A turnover
rate of 100% would occur, for example, if the Fund sold and replaced securities
valued at 100% of its total net assets within a one-year period.)
    

INVESTMENT POLICIES

Besides investing in undervalued common stocks, the Fund may follow a number of
investment policies to achieve its objectives.

   
                                PLAIN TALK ABOUT
                            PORTFOLIO DIVERSIFICATION

In general, the more diversified a fund's portfolio of stocks, the less likely
that a specific stock's poor performance will hurt the fund. One measure of a
fund's level of diversification is the percentage of total net assets
represented by its ten largest holdings. The average U.S. equity mutual fund has
about 30% of its assets invested in its ten largest holdings, while some less
diversified mutual funds have 50% or more of their assets invested in the stocks
of just ten companies.

                                PLAIN TALK ABOUT
                               PORTFOLIO TURNOVER

Before investing in a mutual fund, you should review its portfolio turnover rate
for an indication of the potential effect of transaction costs on 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. The average turnover rate for all domestic stock
funds is approximately 80%.

   The Fund may invest as much as 20% of its assets in securities of companies
based outside the United States and may engage in currency transactions. These
securities can be traded in either U.S. or foreign markets.

     [FLAG]    THE FUND IS SUBJECT TO COUNTRY RISK AND CURRENCY RISK. COUNTRY
               RISK IS THE POSSIBILITY THAT POLITICAL EVENTS (SUCH AS A WAR),
               FINANCIAL PROBLEMS (SUCH AS GOVERNMENT DEFAULT), OR NATURAL
               DISASTERS (SUCH AS AN EARTHQUAKE) WILL WEAKEN A COUNTRY'S ECONOMY
               AND CAUSE INVESTMENTS IN THAT COUNTRY TO LOSE MONEY. CURRENCY
               RISK IS THE POSSIBILITY THAT A "STRONGER" U.S. DOLLAR WILL REDUCE
               RETURNS FOR AMERICANS INVESTING OVERSEAS. GENERALLY, WHEN THE

   The Fund may invest in money market instruments, fixed-income securities,
convertible securities, and other equity securities such as preferred stock. The
Fund may invest up to 15% of its assets in restricted securities with limited
marketability or other illiquid securities.
    

     [FLAG]    THE FUND RESERVES THE RIGHT TO INVEST, TO A LIMITED EXTENT, IN
               STOCK FUTURES AND OPTIONS CONTRACTS, WHICH ARE TRADITIONAL TYPES
               OF DERIVATIVES.
   
   Losses (or gains) involving futures 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 portfolio. The Fund will not use
futures and options for speculative purposes or as leveraged investments that
magnify the gains or losses of an investment. Rather, the Fund will keep
separate cash reserves or other liquid portfolio securities in the amount of the
obligation underlying the futures or options contract. Only a limited percentage
of the Fund's assets--5%--may be applied toward the deposits required on futures
contracts, and the value of all futures contracts in which the Fund acquires an
interest cannot exceed 20% of the Fund's total assets.

   The reasons for which the 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 by buying futures instead of actual
   stocks.
- -  To add value to the Fund by buying futures instead of actual stocks when
   futures are cheaper.
    


                                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, exotic types of derivatives--some of which can
carry considerable risks.

                                PLAIN TALK ABOUT
                                  CASH RESERVES
With mutual funds, holding cash reserves--or "cash"--does not mean literally
that the fund holds a stack of currency. Rather, cash reserves refer to
short-term, interest-bearing securities that can easily and quickly be converted
to cash. (Most mutual funds keep at least a small percentage of assets in cash
to accommodate shareholder redemptions.) While some funds strive to keep cash
levels at a minimum and to always remain fully invested in stocks, other funds
allow investment advisers to hold up to 20% of a fund's assets in cash reserves.



                                       8
<PAGE>   85
   The Fund will usually hold only a small percentage of its assets in cash
reserves, although if an investment adviser believes that market conditions
warrant a temporary defensive measure, the Fund may hold cash reserves without
limit.

INVESTMENT LIMITATIONS

   
The Fund has adopted limitations on some of its investment policies. Some of
these limitations are that the Fund will not:
- -  Invest more than 25% of its assets in any one industry.
- -  Borrow money, except for temporary or emergency purposes in an amount not
   exceeding 10% of its net assets. Whenever the Fund's outstanding borrowing is
   more than 5% of its assets, it will stop making investments. 
   With respect to 75% of its assets, the Fund will not:
- -  Invest more than 5% in the securities of any one company.
- -  Buy more than 10% of the outstanding voting shares of any company.
   A complete list of the Fund's investment limitations can be found in the
Statement of Additional Information. These limitations are fundamental and may
be changed only by approval of a majority of the Fund's shareholders.
    


INVESTMENT PERFORMANCE

   
Vanguard/Windsor II invests primarily in common stocks, so its performance is
closely correlated to the performance of the overall stock market. Historically,
stock market performance has been characterized by sharp up-and-down swings in
the short term and by more stable growth over the long term.

                                PAST PERFORMANCE
Whenever you see information on a fund's performance, do not consider the
figures to be an indication of the performance you could expect by making an
investment in the fund today. The past is an imperfect guide to the future;
history does not repeat itself in neat, predictable patterns.

does not make any allowances for federal, state, or local income taxes
that shareholders must pay on a current basis.

     In weighing these performance figures, note that the Fund has been in
operation since June 24, 1985. BHM&S has been adviser for the majority of Fund
assets from the Fund's inception. Equinox, Tukman, and Vanguard Core Management
Group were added as advisers on November 1, 1991.


SHARE PRICE

The Fund's share price, also called its net asset value, or NAV, is calculated
each business day after the close of trading (generally 4 p.m. Eastern time) on
the New York Stock Exchange. The net asset value per share is calculated by
adding up the total assets of the Fund, subtracting all its liabilities, or
debts, and then dividing by the total number of Fund shares outstanding:

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

   The daily net asset value is useful to you as a shareholder because the NAV,
multiplied by the number of Fund 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.

   
   The 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 Fund's name, but the most common is WNDSRII.
    


DIVIDENDS, CAPITAL GAINS, AND TAXES

   
Each June and December, the Fund distributes to its shareholders virtually all
of its income from interest and dividends. Any capital gains realized from the
sale of securities are distributed in December. In addition, the Fund may
occasionally be required to make supplemental dividend or capital gains
distributions at other times during the year.
   If you own shares of the Fund as an investment option in an
employer-sponsored retirement or savings plan, these dividend and capital gains
distributions will be reinvested in additional Fund shares and accumulate on a
tax-deferred basis. You will not owe taxes on these distributions until you
begin withdrawals. You should consult your plan administrator, your plan's
Summary Plan Document, or your tax adviser about the tax consequences of an
investment in the Fund and of any plan withdrawals.
   If your Vanguard/Windsor II investment is not part of an employer-sponsored
plan, you can receive distributions of income or capital gains in cash, or you
may have them automatically re-invested in more shares of the Fund. Both
dividend and capital

                                  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 capital gains distribution. Income
dividends come from the dividends that a fund earns from its holdings as well as
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. These 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.

                                       10

gains distributions--whether received in cash or reinvested in additional
shares--are subject to federal (and possibly state and local) income taxes, no
matter how long you have held the shares in the Fund. You should consult your
tax adviser about other tax consequences of an investment in the Fund.


   
THE FUND AND VANGUARD

Vanguard/Windsor II is a member of The Vanguard Group, a family of more than 30
investment companies with more than 95 distinct investment portfolios and total
net assets of more than $320 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 marketing fees, each fund pays its
allocated share of The Vanguard Group's costs.

 A list of the Fund's Directors and officers, and their present positions and
principal occupations during the past five years, can be found in the Statement
of Additional Information.


INVESTMENT ADVISERS

The Fund employs four investment advisers. Each manages its portion of the
Fund's assets subject to the control of the Directors and officers of the Fund.

   
 Barrow, Hanley, Mewhinney & Strauss, Inc. (BHM&S), One McKinney Plaza, 3232
McKinney Avenue, 15th Floor, Dallas, TX 75204, is an investment advisory firm
founded in 1979. BHM&S is owned by United Asset Management, 1 International
Place, Boston, MA 02110. BHM&S currently manages approximately $27 billion in
stock and bond portfolios.
    

 BHM&S is paid a quarterly advisory fee that is based on the average month-end
Fund assets it manages:

 BHM&S's advisory fee may be adjusted based on the total return performance of
its portion of the Fund as compared to that of the Standard & Poor's/BARRA Value
Index, a benchmark of stocks from the S&P 500 Index with lower than average
price/book ratios. Under the fee schedule, BHM&S's basic fee may be increased or
decreased by as much as 25%.

                     VANGUARD'S UNIQUE CORPORATE STRUCTURE

The Vanguard Group, Inc., is the only MUTUAL mutual fund company. It is owned
jointly by the funds it oversees and by the shareholders in those funds. 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 bought the
management company's publicly traded stock. Because of its structure, Vanguard
operates its funds at cost. Instead of distributing profits from operations to a
separate management company, Vanguard returns profits to fund shareholders in
the form of lower operating expenses.

transactions. At times, the advisers may choose brokers who charge higher
commissions in the interest of obtaining better execution of a transaction. If
more than one broker can obtain the best available price and favorable execution
of a transaction, then the advisers are authorized to choose a broker who, in
addition to executing the transaction, will provide research services to the
advisers or the Fund. However, the advisers will not pay higher commissions
specifically for the purpose of obtaining research services. The Fund may direct
the advisers to use a particular broker for certain transactions in exchange for
commission rebates or research services provided to the Fund.

 The Board of Directors may, without prior approval from shareholders, change
the terms of the advisory agreements or hire a new investment adviser as either
a replacement adviser or as an additional adviser. However, no such change would
be made before giving shareholders 30 days' notice, in writing.


GENERAL INFORMATION

Vanguard/Windsor II is one of two Funds of Vanguard/Windsor Funds, Inc., which
is organized under the laws of the state of Maryland. The other Fund is
Vanguard/Windsor Fund (which is not open to new investors). The two Funds are
combined under one corporation for administrative purposes, but for investment
management purposes operate like separate companies.

 Shareholders of Vanguard/Windsor II have rights and privileges similar to
those enjoyed by other corporate shareholders. For example, shareholders will
not be responsible for any liabilities of the corporation. If any matters are to
be voted on by shareholders (such as a change in a fundamental investment
objective or the election of Directors), each share outstanding at that point
would be entitled to one vote. Annual meetings will not be held by the Fund
except as required by the Investment Company Act of 1940. A meeting will be
scheduled to vote on the removal of a Director if the holders of at least 10% of
the Fund's shares request a meeting in writing.

INVESTING WITH VANGUARD

FOR PLAN PARTICIPANTS

Vanguard/Windsor II is an investment option in your retirement or savings plan.
Your plan administrator or your employee benefits office can provide you with
detailed information on how to participate in your plan and how to elect the
Fund as an investment option.


   
- -        If you have any questions about the Fund or Vanguard, including the
         Fund's investment objectives, strategy, or risks, contact Vanguard's
         Participant Services Center, toll-free, at 1-800-523-1188.
    

- -        If you have questions about your account, contact your plan
         administrator or the organization that provides recordkeeping services
         for your plan.

INVESTMENT OPTIONS AND ALLOCATIONS

Your plan's specific provisions may allow you to change your investment
selections, the amount of your contributions, or how your contributions are
allocated among the investment choices available to you. Contact your plan
administrator or employee benefits office for more details.

TRANSACTIONS

Contributions, exchanges, or redemptions of the Fund's shares are processed as
soon as they have been received by Vanguard in good order. Good order means that
your request includes complete information on your contribution, exchange, or
redemption, and that Vanguard has received the appropriate assets.

EXCHANGES
   
The exchange privilege (your ability to redeem shares from one fund to purchase
shares of another fund) may be available to you through your plan. Although we
make every effort to maintain the exchange privilege, Vanguard reserves the
right to revise or terminate the exchange privilege, limit the amount of an
exchange, or reject any exchange, at any time, without notice. Because excessive
exchanges can potentially disrupt the management of a Fund and increase its
transaction costs, Vanguard limits exchange activity to TWO SUBSTANTIVE EXCHANGE
REDEMPTIONS (at least 30 days apart) from any Fund during any 12-month period.
"Substantive" means either a dollar amount or a series of movements between
Vanguard funds that Vanguard determines, in its sole discretion, could have a
negative impact on the management of the Fund. In addition, certain investment
options, particularly funds made up of company stock or investment contracts,
may be subject to unique restrictions. Contact your plan administrator for
details on the exchange policies that apply to your plan.

         Before making an exchange, you should consider the following:

- -        Before you exchange to another Vanguard fund available in your plan,
         you should read that fund's prospectus. Contact Vanguard's Participant
         Services Center, toll-free, at 1-800-523-1188 for a copy.

- -        Vanguard can accept exchanges only as permitted by your plan. Your plan
         administrator can explain how frequently exchanges are allowed.

TRANSACTIONS

bought, exchanged, or sold will be the Fund's next-determined net asset value
after Vanguard has processed your request, provided your request has been
received before the close of trading on the New York Stock Exchange (generally 4
p.m. Eastern time).
    

         Vanguard must consider the interests of all Fund shareholders and so
         reserves the right to:

- -        Delay or reject any purchase or exchange request that may disrupt the
         Fund's operation or performance.

- -        Revise or terminate the exchange privilege or limit the amount of an
         exchange, at any time, without notice.

- -        Take up to seven days to deliver your redemption proceeds.

                                  THE COMPANY
 
   
     Vanguard/Windsor Funds, Inc. (the "Company") is an open-end, diversified,
investment management company whose shares are currently offered in two separate
series -- the Vanguard/Windsor Fund series and the Vanguard/Windsor II series.
Each series in effect represents a separate mutual fund. Vanguard/Windsor Fund
series has been offered under the name "Windsor Fund" since 1958. Shares of
Vanguard/Windsor II were initially offered on June 24, 1985. Wellington
Management Company, LLP ("WMC") has served as investment adviser to the
Vanguard/Windsor Fund series since its inception. Barrow, Hanley, Mewhinney &
Strauss, Inc. ("BHM&S"), Equinox Capital Management, Inc. ("Equinox") and Tukman
Capital Management, Inc. ("Tukman"), three separate and distinct investment
counseling firms that have no affiliation with WMC, nor with each other, serve
as investment advisers to the Vanguard/Windsor II series. Additionally, Vanguard
Core Management Group provides investment advisory services on an at-cost basis
with respect to a portion of Vanguard/Windsor II's assets.
    
 
                       INVESTMENT OBJECTIVES AND POLICIES
 
     The following policies supplement the investment objectives and policies
set forth in each of the Company's Prospectuses.
 
     REPURCHASE AGREEMENTS.  Each series may invest in repurchase agreements
with domestic banks, or brokers or dealers, either for temporary defensive
purposes due to market conditions, or to generate income from its excess cash
balances. A repurchase agreement is an agreement under which the series 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
domestic 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
series and is unrelated to the interest rate on the underlying
 
                                       B-1
<PAGE>   96
 
   
instrument. In these transactions, the securities acquired by the series
(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 Board of Directors will monitor the repurchase
agreement transactions for each series 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 Company. No
more than an aggregate of 15% of a series' assets, at the time of investment,
will be invested in repurchase agreements having maturities longer than seven
days and in securities subject to legal or contractual restrictions on resale
for which there are no readily available market quotations. See "Illiquid
Securities" on page B-3.
    
 
     The use of repurchase agreements involves certain risks. For example, if
the seller of the securities under an agreement defaults on its obligation to
repurchase the underlying securities at a time when the value of these
securities has declined, the series may incur a loss upon disposition of them.
If the seller becomes insolvent and subject to liquidation or reorganization
under bankruptcy or other laws, a bankruptcy court may determine that the
underlying securities are collateral for a loan by the series not within the
control of the series and therefore subject to sale by the trustee in
bankruptcy. Finally, it is possible that the series may not be able to
substantiate its interest in the underlying securities. While the Company's
management acknowledges these risks, it is expected that they can be controlled
through careful monitoring procedures.
 
   
     LENDING OF SECURITIES.  Each series may lend its portfolio securities for
either short or long-term periods to qualified institutional investors 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 portfolio securities, each series attempts to
increase its income through the receipt of interest on the loan. Any gain or
loss in the market price of the securities loaned that might occur during the
term of the loan would be for the account of the series. Each series may lend
its portfolio securities to qualified brokers, dealers, domestic banks or other
domestic financial institutions, so long as the terms, and the structure of such
loans are not inconsistent with the Investment Company Act of 1940, or the Rules
and Regulations or interpretations of the Securities and Exchange Commission
(the "Commission") thereunder, which currently require that (a) the borrower
pledge and maintain with the series collateral consisting of cash, an
irrevocable letter of credit or securities issued or guaranteed by a domestic
bank or the United States Government having a value at all times not less than
100% of the value of the securities loaned, (b) the borrower add to such
collateral whenever the price of the securities loaned rises (i.e., the borrower
"marks to the market" on a daily basis), (c) the loan be made subject to
termination by the series at any time, and (d) the series receive reasonable
interest on the loan (which may include the series investing any cash collateral
in interest bearing short-term investments), any distributions on the loaned
securities and any increase in their market value. A series will not lend
portfolio securities if, as a result, the aggregate of such loans exceeds
33 1/3% of the value of the series' net assets. Loan arrangements made will
comply with all other applicable regulatory requirements, including the rules of
the New York Stock Exchange, which rules 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 Board of
Directors.
    
 
     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 Directors (Trustees). In addition, voting
rights pass with the loaned securities, but if a material event occurs affecting
an investment on loan, the loan must be called and the securities voted.
 
     FOREIGN INVESTMENTS.  As indicated in the Prospectus, Vanguard/Windsor Fund
may include foreign securities to a certain extent. Investors should recognize
that investing in foreign companies involves certain special considerations
which are not typically associated with investing in U.S. companies.
 
     Country Risk.  As foreign companies are not generally subject to uniform
accounting, auditing and financial reporting standards and practices comparable
to those applicable to domestic companies, there may be less publicly available
information about certain foreign companies than about domestic companies.
 
                                       B-2
<PAGE>   97
 
Securities of some foreign companies are generally less liquid and more volatile
than securities of comparable domestic companies. There is generally less
government supervision and regulation of stock exchanges, brokers and listed
companies than in the U.S. In addition, with respect to certain foreign
countries, there is the possibility of expropriation or confiscatory taxation,
political or social instability, or diplomatic developments which could affect
U.S. investments in companies in those countries.
 
   
     Although Vanguard/Windsor Fund will endeavor to achieve the most favorable
execution costs in its portfolio transactions in foreign securities, fixed
commissions on many foreign stock exchanges are generally higher than negotiated
commissions on U.S. exchanges. In addition, it is expected that the expenses for
custodial arrangements of the Series foreign securities will be somewhat greater
than the expenses for the custodial arrangement for handling U.S. securities of
equal value.
    
 
     Certain foreign governments levy withholding taxes against dividend and
interest income. Although in some countries a portion of these taxes is
recoverable, the non-recovered portion of foreign withholding taxes will reduce
the income Vanguard/Windsor Fund receives from its foreign investments.
 
     Currency Risk.  Since the stocks of foreign companies are frequently
denominated in foreign currencies, and since Vanguard/Windsor Fund may
temporarily hold uninvested reserves in bank deposits in foreign currencies, the
Fund will be affected favorably or unfavorably by changes in currency rates and
in exchange control regulations, and may incur costs in connection with
conversions between various currencies. The investment policies of
Vanguard/Windsor Fund permit it to enter into forward foreign currency exchange
contracts in order to hedge holdings and commitments against changes in the
level of future currency rates. Such contracts involve an obligation to purchase
or sell a specific currency at a future date at a price set at the time of the
contract.
 
   
     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 a fund's
books. An illiquid security includes repurchase agreements which have a maturity
of longer than seven days, securities which are illiquid by virtue of the
absence of a readily available market, and demand instruments with a demand
notice exceeding seven days. Illiquid securities may include securities that are
not registered under the Securities Act of 1933 (the "1933 Act"); however,
unregistered securities that can be sold to "qualified institutional buyers" in
accordance with Rule 144A under the 1933 Act will not be considered illiquid so
long as it is determined by the fund's advisor that an adequate trading market
exists for the security.
    
 
   
     FUTURES CONTRACTS.  Each series may enter into stock futures contracts,
options, and options on futures contracts only for the purpose of remaining
fully invested and reducing transactions costs. Futures contracts provide for
the future sale by one party and purchase by another party of a specified amount
of a specific security at a specified future time and at a specified price.
Futures contracts which are standardized as to maturity date and underlying
financial instrument are traded on national futures exchanges. Futures exchanges
and trading are regulated under the Commodity Exchange Act by the Commodity
Futures Trading Commission ("CFTC"), a U.S. Government agency. Assets committed
to futures contracts will be segregated at the Fund's custodian bank to the
extent required by law.
    
 
     Although futures contracts by their terms call for actual delivery or
acceptance of the underlying securities, in most cases the contracts are closed
out before the settlement date without the making or taking of delivery. Closing
out an open futures position is done by taking an opposite position ("buying" a
contract which has previously been "sold," "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
 
                                       B-3
<PAGE>   98
 
exchange minimums. Futures contracts are customarily purchased and sold on
margin that may range upward from less than 5% of the value of the contract
being traded.
 
     After a futures contract position is opened, the value of the contract is
marked to market daily. If the futures contract price changes to the extent that
the margin on deposit does not satisfy margin requirements, payment of
additional "variation" margin will be required. Conversely, a 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. Each series
expects to earn interest income on its margin deposits.
 
     Traders in futures contracts may be broadly classified as either "hedgers"
or "speculators." Hedgers use the futures markets primarily to offset
unfavorable changes in the value of securities otherwise held for investment
purposes or expected to be acquired by them. Speculators are less inclined to
own the securities underlying the futures contracts which they trade, and use
futures contracts with the expectation of realizing profits from fluctuations in
interest rates. Each series intends to use futures contracts only for bona fide
hedging purposes.
 
   
     Regulations of the CFTC applicable to the Company require that all of each
of the series' futures transactions constitute bona fide hedging transactions
except to the extent that the aggregate initial margins and premiums required to
establish any non-hedging positions do not exceed five percent of the value of
the Fund's portfolio. Each series will only sell futures contracts to protect
securities it owns against price declines or purchase contracts to protect
against an increase in the price of securities it intends to purchase. As
evidence of this hedging interest, each series expects that approximately 75% of
its futures contract purchases will be "completed;" that is, equivalent amounts
of related securities will have been purchased or are being purchased by the
series upon sale of open futures contracts.
    
 
     Although techniques other than the sale and purchase of futures contracts
could be used to control the exposure of the series' income to market
fluctuations, the use of futures contracts may be a more effective means of
hedging this exposure. While each series will incur commission expenses in both
opening and closing out futures positions, these costs are lower than
transaction costs incurred in the purchase and sale of portfolio securities.
 
   
     RESTRICTIONS ON THE USE OF FUTURES CONTRACTS.  A series will not enter into
futures contract transactions to the extent that, immediately thereafter, the
sum of its initial margin deposits on open contracts exceeds 5% of the market
value of the series' total assets. In addition, a series will not enter into
futures contracts to the extent that its outstanding obligations to purchase
securities under these contracts would exceed 20% of the series' total assets.
Assets committed to futures contracts or options will be held in a segregated
account at the Company's custodian bank.
    
 
     RISK FACTORS IN FUTURES TRANSACTIONS.  Positions in futures contracts may
be closed out only on an exchange which provides a secondary market for such
futures. However, there can be no assurance that a liquid secondary market will
exist for any particular futures contract at any specific time. Thus, it may not
be possible to close a futures position. In the event of adverse price
movements, a series would continue to be required to make daily cash payments to
maintain its required margin. In such situations, if a series 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 series may be
required to make delivery of the instruments underlying interest rate futures
contracts it holds. The inability to close options and futures positions also
could have an adverse impact on the ability to effectively hedge its portfolio.
A series will minimize the risk that it will be unable to close out a futures
contract by only entering into futures contracts 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 to the extremely high degree of leverage involved in futures
pricing. As a result, a relatively small price movement in a futures contract
may result in immediate and substantial loss (as well as gain) to the investor.
For example, if at the time of purchase, 10% of the value of the futures
contract is deposited as margin, a subsequent 10% decrease in the value of the
futures contract would result in a total loss of the margin deposit, before any
deduction for
 
                                       B-4
<PAGE>   99
 
   
the transaction costs, if the account were then closed out. A 15% decrease would
result in a loss equal to 150% of the original margin deposit if the contract
were closed out. Thus, a purchase or sale of a futures contract may result in
losses in excess of the amount invested in the contract. However, because the
futures strategies of the series are engaged in only for hedging purposes, the
advisers do not believe that the series are subject to the risks of loss
frequently associated with futures transactions. Either series would presumably
have sustained comparable losses if, instead of the futures contract, it had
invested in the underlying security and sold it after the decline.
    
 
     There is the risk of loss by a series of margin deposits in the event of
bankruptcy of a broker with whom the series has an open position in a futures
contract or related option. Additionally, investments in futures and options
involve the risk that the investment adviser will incorrectly predict stock
market and interest rate trends.
 
     Most futures exchanges limit the amount of fluctuation permitted in futures
contract prices during a single trading day. The daily limit establishes the
maximum amount that the price of a futures contract may vary either up or down
from the previous day's settlement price at the end of a trading session. Once
the daily limit has been reached in a particular type of contract, no trades may
be made on that day at a price beyond that limit. The daily limit governs only
price movement during a particular trading day and therefore does not limit
potential losses, because the limit may prevent the liquidation of unfavorable
positions. Futures contract prices have occasionally moved to the daily limit
for several consecutive trading days with little or no trading, thereby
preventing prompt liquidation of future positions and subjecting some futures
traders to substantial losses.
 
     FEDERAL TAX TREATMENT OF FUTURES CONTRACTS.  Each series is required for
Federal income tax purposes to recognize as income for each taxable year its net
unrealized gains and losses on 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 series may affect the holding period of such securities and, consequently, the
nature of the gain or loss on such securities upon disposition. The series 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 series.
 
   
     In order for a series 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, and gains from the sale of
securities or foreign currencies, or other income derived from the series'
business of investing in securities or currencies. It is anticipated that any
net gain realized from the closing of futures contracts will be considered gain
from the sale of securities and therefore be qualifying income for purposes of
the 90% requirement.
    
 
     Each series 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 series' fiscal year on futures transactions. Such
distributions will be combined with distributions of capital gains realized on
the series' other investments and shareholders will be advised on the nature of
the payments.
 
   
                                  SHARE PRICE
    
 
   
     Each Series' share price, or "net asset value" per share, is calculated by
dividing the total assets of the series, 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.
    
 
   
     Series 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. 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 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.
    
 
   
     Foreign securities are valued at the last quoted sales price, according to
the broadest and most representative market, available at the time the series is
valued. If events which materially affect the value of a series' investments
occur after the close of the securities markets on which such securities are
primarily traded, those investments may be valued by such methods as the Board
of Directors deems in good faith to reflect fair value.
    
 
   
     In determining the series' net asset value per share, all assets and
liabilities initially expressed in foreign currencies will be converted into
U.S. dollars using the officially quoted daily exchange rates used by Morgan
Stanley Capital International in the calculating of their various benchmarking
indices. This officially quoted exchange rate may be determined prior to or
after the close of a particular securities market. If such quotations are not
available, the rate of exchange will be determined in accordance with policies
established in good faith by the Board of Directors.
    
 
   
     Other assets and securities for which no quotations are readily available
or which are restricted as to sale (or resale) are valued by such methods as the
Board of Directors deems in good faith to reflect fair value.
    
 
   
     The share price for the series can be found daily in the mutual fund
listings of most major newspapers under the heading of Vanguard Funds.
    
 
                               PURCHASE OF SHARES
 
     The purchase price of shares of each series of the Company is the net asset
value next determined after the order is received in Good Order, as defined in
the Prospectus. The net asset value is calculated as of the close of the New
York Stock Exchange on each day the Exchange is open for business. An order
received prior to the close of the Exchange will be executed at the price
computed on the date of receipt; and an order received after the close of the
Exchange will be executed at the price computed on the next day the Exchange is
open.
 
     Each series 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 series, and (iii) to
reduce or waive the minimum investment for or any other restrictions on initial
and subsequent investments for certain fiduciary accounts such as employee
benefit plans or under circumstances where certain economies can be achieved in
sales of the series' shares. Vanguard/Windsor Fund is currently closed to new
investors. Existing shareholders may purchase additional shares, but may not
invest more than $25,000 each year.
 
                              REDEMPTION OF SHARES
 
   
     Each series 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 Commission; (ii)
during any period when an emergency exists, as defined by the rules of the
Commission, as a result of which it is not reasonably practicable for the series
to dispose of securities owned by it, or to determine fairly the value of its
assets; and (iii) for such other periods as the Commission may permit.
    
 
                                       B-6
<PAGE>   101
 
     The Company 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 a series at
the beginning of such period. Such commitment is irrevocable without 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 Directors may deem advisable; however, payment will be made wholly
in cash unless the Directors believe that economic or market conditions exist
which would make such a practice detrimental to the best interests of the
Company. If redemptions are paid in investment securities, such securities will
be valued as set forth in the Prospectus for the appropriate series, and a
redeeming shareholder would normally incur brokerage expenses if he converted
these securities to cash.
 
     No charge is made by the Company for redemptions. Any redemption may be
more or less than the shareholder's cost, depending on the market value of the
series' portfolio securities.
 
     SIGNATURE GUARANTEES.  To protect your account, the Company and Vanguard
from fraud, signature guarantees are required for certain redemptions. A
signature guarantee verifies the authenticity of your signature. Examples of
situations in which signature guarantees are required are: (1) ALL REDEMPTIONS,
REGARDLESS OF THE AMOUNT INVOLVED, WHEN THE PROCEEDS ARE TO BE PAID TO SOMEONE
OTHER THAN THE REGISTERED ACCOUNT OWNER(S) AND/OR TO AN ADDRESS OTHER THAN THE
ADDRESS OF RECORD; AND (2) SHARE TRANSFER REQUESTS. These requirements are not
applicable to redemptions in Vanguard's prototype retirement plans, except in
connection with: (1) distributions made when the proceeds are to be paid to
someone other than the plan participant; (2) certain authorizations to effect
exchanges by telephone; and (3) when proceeds are to be wired. These
requirements may be waived by the Company in certain instances.
 
     Signature guarantees can be obtained from a bank, broker or any other
guarantor that Vanguard deems acceptable. NOTARIES PUBLIC ARE NOT ACCEPTABLE
GUARANTORS.
 
                             YIELD AND TOTAL RETURN
 
   
     The yield of Vanguard/Windsor Fund for the thirty-day period ended October
31, 1997 was +1.59%, and the yield for Vanguard/Windsor II for the same period
was +2.38%.
    
 
   
     The average annual total returns for Vanguard/Windsor Fund for the one-,
five- and ten-year periods ending October 31, 1997 were +27.04%, +20.25% and
+15.60%, respectively. The average annual total returns for the one-, five- and
ten-year periods for Vanguard/Windsor II were +31.27%, +20.21% and +16.95%,
respectively. Total return is computed by determining the average compounded
rates of return over the one-, five- and ten-year periods set forth above that
would equate an initial amount invested at the beginning of the periods to the
ending redeemable value of the investment.
    
 
                             INVESTMENT LIMITATIONS
 
     Each series of the Company is subject to the following restrictions which
may not be changed without the approval of at least a majority of the
outstanding voting securities of that series. A series will not:
 
     1) with respect to 75% of the value of its total assets, purchase the
        securities of any issuer (except obligations of the United States
        government and its instrumentalities) if as a result the series would
        hold more than 10% of the outstanding voting securities of the issuer,
        or more than 5% of the value of the total assets of the series would be
        invested in the securities of such issuer;
 
     2) invest in securities of other investment companies, except as may be
        acquired as a part of a merger, consolidation or acquisition of assets
        approved by the shareholders of the series or otherwise to the extent
        permitted by Section 12 of the Investment Company Act of 1940. A series
        will invest only in investment companies which have investment
        objectives and investment policies consistent with those of that series;
 
     3) borrow money, except that a series may borrow from banks (or through
        reverse repurchase agreements), for temporary or emergency (not
        leveraging) purposes, including the meeting of redemption
 
                                       B-7
<PAGE>   102
 
        requests which might otherwise require the untimely disposition of
        securities, in an amount not exceeding 10% of the value of the net
        assets of the series (including the amount borrowed and the value of any
        outstanding reverse repurchase agreements) at the time the borrowing is
        made. Whenever borrowings exceed 5% of the value of the net assets of
        the series, the series will not make any additional investments;
 
   
     4) purchase securities on margin, or sell securities short, except that
        each series may invest in stock futures contracts, stock options and
        options on stock futures contracts to the extent that not more than 5%
        of a series' assets are required as deposit on a futures contract and
        not more than 20% of a series' assets are invested in futures contracts
        and options transactions at any time;
    
 
     5) purchase or otherwise acquire any security if, as a result, more than
        15% of its net assets would be invested in securities that are illiquid
        (including any investment in The Vanguard Group, Inc.);
 
     6) invest for the purpose of exercising control over management of any
        company;
 
     7) purchase or retain securities of any company in which those Officers and
        Directors of the Company and/or its investment advisers owning more than
        1/2 of 1% of such securities, own in the aggregate more than 5% of such
        securities;
 
     8) make loans, except (i) by purchasing bonds, debentures or similar
        obligations (including repurchase agreements) which are either publicly
        distributed or customarily purchased by institutional investors, and
        (ii) as provided under "Lending of Securities" (See page B-2);
 
     9) purchase assessable securities;
 
   10) engage in the business of underwriting securities issued by other
       persons, except to the extent that the series may technically be deemed
       to be an underwriter under the Securities Act of 1933, as amended, in
       disposing of investment securities;
 
   11) purchase real estate, commodities or commodity contracts except as
       described above in "(4)"; or
 
   12) invest more than 25% of the value of its total assets in any one
       industry.
 
     Notwithstanding these limitations, each series of the Company may own all
or any portion of the securities of, or make loans to, or contribute to the
costs or other financial requirements of any company which will be wholly owned
by the Company and one or more other investment companies and is primarily
engaged in the business of providing, at-cost, management, administrative or
related services to the Company and other investment companies. See "Management
of the Company".
 
     These investment limitations are considered at the time investment
securities are purchased.

THE VANGUARD GROUP
 
     The Company is a member of The Vanguard Group of Investment Companies.
Through their jointly-owned subsidiary, The Vanguard Group, Inc. ("Vanguard"),
the Company and the other Funds in the Group obtain at cost virtually all of
their corporate management, administrative and distribution services. Vanguard
also provides investment advisory services on an at-cost basis to certain of the
Vanguard Funds.
 
     Vanguard employs a supporting staff of management and administrative
personnel needed to provide the requisite services to the Funds and also
furnishes the Funds with necessary office space, furnishings and equipment. Each
Fund pays its share of Vanguard's total expenses which are allocated among the
Funds under methods approved by the Board of Directors (Trustees) of each Fund.
In addition, each Fund bears its own direct expenses, such as legal, auditing
and custodian fees.
 
     The Funds' Officers are also Officers and employees of Vanguard. No Officer
or employee owns, or is permitted to own, any securities of any external adviser
for the Funds.
 
     The Vanguard Group adheres to a Code of Ethics established pursuant to Rule
17 j-1 under the Investment Company Act of 1940. The Code is designed to prevent
unlawful practices in connection with the purchase or sale of securities by
persons associated with Vanguard. Under Vanguard's Code of Ethics certain
officers and employees of Vanguard who are considered access persons are
permitted to engage in personal securities transactions. However, such
transactions are subject to procedures and guidelines substantially similar to
those recommended by the mutual fund industry and approved by the U.S.
Securities and Exchange Commission.
 
   
     The Vanguard Group was established and operates under a Funds' Service
Agreement which was approved by the shareholders of each of the Funds. The
amounts which each of the Funds has invested in Vanguard are adjusted from time
to time in order to maintain the proportionate relationship between each Fund's
relative net assets and its contribution to Vanguard's capital. At October 31,
1997, Vanguard/Windsor Fund had contributed capital of $1,480,000 to Vanguard,
representing 7.4% of Vanguard's capitalization and, at that time,
Vanguard/Windsor II had contributed capital of $1,534,000 to Vanguard,
representing 7.7% of Vanguard's capitalization. The Funds' Service Agreement
provides for the following arrangement: (a) each Vanguard Fund may invest up to
0.40% of its current net assets in Vanguard and (b) there is no other limitation
on the amount that each Vanguard Fund may contribute to Vanguard's
capitalization.
    
 
   
     MANAGEMENT.  Corporate management and administrative services include: (1)
executive staff; (2) accounting and financial; (3) legal and regulatory; (4)
shareholder account maintenance; (5) monitoring and control of custodian
relationships; (6) shareholder reporting; and (7) review and evaluation of
advisory and other services provided to the Funds by third parties. During the
fiscal year ended October 31, 1997, Vanguard/Windsor Fund's share of Vanguard's
actual net costs of operation relating to management and administrative services
(including transfer agency) totaled approximately $34,169,000 and Vanguard/
Windsor II's share of such costs of operation totaled approximately $36,562,000.
    
 
   
     DISTRIBUTION.  Vanguard provides all distribution and marketing activities
for the Funds in the Group. Vanguard Marketing Corporation, a wholly-owned
subsidiary of Vanguard, acts as Sales Agent for shares of the Funds in
connection with any sales made directly to investors in the states of Florida,
Missouri, New York, Ohio, Texas and such other states as may be required.
    
 
     The principal distribution expenses are for advertising, promotional
materials and marketing personnel. Distribution services may also include
organizing and offering to the public, from time to time, one or more new
investment companies which will become members of the Group. The Directors and
Officers of Vanguard determine the amount to be spent annually on distribution
activities, the manner and amount to be spent on each Fund, and whether to
organize new investment companies.
 
     One half of the distribution expenses of a marketing and promotional nature
is allocated among the Funds based upon their relative net assets. The remaining
one half of these expenses is allocated among the Funds based upon each Fund's
sales for the preceding 24 months relative to the total sales of the Funds as a
Group, provided, however, that no Fund's aggregate quarterly rate of
contribution for distribution expenses of
 
                                      B-10
<PAGE>   105
 
   
a marketing and promotional nature shall exceed 125% of the average distribution
expense rate for the Group, and no Fund shall incur annual distribution expenses
in excess of .02 of 1% of its average month-end net assets. During the fiscal
year ended October 31, 1997, Vanguard/Windsor Fund paid approximately $3,358,000
of the Group's distribution and marketing expenses, which represented an
effective annual rate of .02 of 1% of Vanguard/Windsor Fund's average net assets
and Vanguard/Windsor II paid approximately $3,669,000 of such expenses which
represented an effective annual rate of .02 of 1% of Vanguard/Windsor II's net
assets.
    
 
   
     INVESTMENT ADVISORY SERVICES.  Vanguard also provides investment advisory
services to Vanguard Windsor II, Vanguard Money Market Reserves, Vanguard
Municipal Bond Fund, several Portfolios of Vanguard Fixed Income Securities
Fund, Vanguard Pennsylvania Tax-Free Fund, Vanguard California Tax-Free Fund,
Vanguard New York Tax-Free Fund, Vanguard New Jersey Tax-Free Fund, Vanguard
Ohio Tax-Free Fund, Vanguard Florida Insured Tax-Free Fund, Vanguard Index
Trust, Vanguard Bond Index Fund, Vanguard International Equity Index Fund,
Vanguard Balanced Index Fund, Vanguard Admiral Funds, the Total International
Portfolio of Vanguard STAR Fund, Vanguard Tax-Managed Fund, Aggressive Growth
Portfolio of Vanguard Horizon Fund, Vanguard Institutional Index Fund, several
Portfolios of Vanguard Variable Insurance Fund, a portion of Vanguard/Morgan
Growth Fund as well as several indexed separate accounts. These services are
provided on an at-cost basis by an investment management staff employed directly
by Vanguard. The compensation and other expenses of this staff are paid by the
Funds utilizing these services.
    
 
REMUNERATION OF DIRECTORS AND OFFICERS
 
   
     The Company pays each Director who is not also an Officer an annual fee
plus travel and other expenses incurred in attending Board meetings. The
Company's Officers and employees are paid by Vanguard which, in turn, is
reimbursed by the Company, and each other Fund in the Group, for its
proportionate share of Officers' and employees' salaries and retirement
benefits. For the fiscal year ended October 31, 1997, the Company's
proportionate share of remuneration for all Officers as a group was
approximately $884,756 and its proportionate share of the amounts contributed to
the retirement plans of all Officers as a group was approximately $22,650.
    
 
     Under its Retirement Plan, Vanguard contributes annually an amount equal to
10% of each Officer's annual compensation plus 5.7% of that part of the
Officer's compensation during the year, if any, that exceeds the Social Security
Taxable Wage Base then in effect. Under the Thrift Plan, all Officers are
permitted to make pre-tax basic contributions in a maximum amount equal to 4% of
total compensation. Vanguard matches the basic contributions on a 100% basis.
Upon retirement, Directors who are not Officers are paid an annual fee based on
the number of years of service on the Board, up to fifteen years of service. The
fee is equal to $1,000 for each year of service and each investment company
member of The Vanguard Group contributes a proportionate amount of this fee
based on its relative net assets. This fee is paid, subsequent to a Director's
retirement, for a period of ten years or until the death of a retired Director.

                          INVESTMENT ADVISORY SERVICES
 
VANGUARD/WINDSOR FUND
 
   
     The Company employs Wellington Management Company, LLP ("WMC") under an
investment advisory agreement dated August 1, 1996 to manage the investment and
reinvestment of the assets of Vanguard/Windsor Fund and to continuously review,
supervise and administer Vanguard/Windsor Fund's investment program. WMC
discharges its responsibilities subject to the control of the Officers and
Directors of the Company. WMC is a Massachusetts limited liability partnership
controlled by the following general partners: Robert W. Doran, Duncan M.
McFarland and John R. Ryan. WMC and its predecessor organizations have provided
investment advisory services to investment companies since 1928 and to
investment counseling clients since 1960. Charles T. Freeman, Senior Vice
President of WMC, has served as portfolio manager of the series since January,
1996.
    
 
     Vanguard/Windsor Fund pays WMC a basic fee at the end of each fiscal
quarter, calculated by applying a quarterly rate, based on the following annual
percentage rates, to Vanguard/Windsor Fund's average month-end net assets for
the quarter.

</TABLE>
 
     The basic fee paid to WMC may be increased or decreased by applying an
adjustment formula based on Vanguard/Windsor Fund's investment performance. Such
formula provides for an increase or decrease in the basic fee paid to WMC each
quarter, depending upon Vanguard/Windsor Fund's investment performance for the
thirty-six months preceding the end of the quarter relative to the investment
record of the Standard and Poor's 500 Composite Stock Price Index (the "Index")
for the same period.

*For purposes of this calculation, the basic fee is calculated by applying the
 quarterly rate against average assets over the 36-month period.
 
     The above incentive/penalty fee will not be fully operable until the
quarter ending July 31, 1999. Until that date, a "blended" fee rate consisting
of varying percentages of (i) the performance adjustment based on the schedule
set forth above (the "new rate"), and (ii) the performance adjustment based on
the schedule set forth in Vanguard/Windsor Fund's previous investment advisory
agreement with WMC((1)) (the "previous rate") shall be used as follows:
 
      1) QUARTER ENDING JANUARY 31, 1997. The incentive/penalty fee was
         calculated as the sum of 16.7% of the fee payable under the new rate
         plus 83.3% of the fee payable under the previous rate.
 
   
      2) QUARTER ENDING APRIL 30, 1997. The incentive/penalty fee was calculated
         as the sum of 25% of the fee payable under the new rate plus 75% of the
         fee payable under the previous rate.
    
 
   
      3) QUARTER ENDING JULY 31, 1997. The incentive/penalty fee was calculated
         as the sum of 33% of the fee payable under the new rate plus 67% of the
         fee payable under the previous rate.
    
 
   
      4) QUARTER ENDING OCTOBER 31, 1997. The incentive/penalty fee was
         calculated as the sum of 41.6% of the fee payable under the new rate
         plus 58.4% of the fee payable under the previous rate.
    
 
   
      5) QUARTER ENDING JANUARY 31, 1998. The incentive/penalty fee was
         calculated as the sum of 50% of the fee payable under the new rate plus
         50% of the fee payable under the previous rate.
    
 
      6) QUARTER ENDING APRIL 30, 1998. The incentive/penalty fee shall be
         calculated as the sum of 58.4% of the fee payable under the new rate
         plus 41.6% of the fee payable under the previous rate.
 
      7) QUARTER ENDING JULY 31, 1998. The incentive/penalty fee shall be
         calculated as the sum of 67% of the fee payable under the new rate plus
         33% of the fee payable under the previous rate.
 
- ---------------
 
   
(1) The previous incentive/penalty fee structure provided that the Basic Fee be
    increased or decreased by an amount equal to .05% per annum (.0125 per
    quarter) of the average month-end assets if the Fund's investment
    performance for the 36 months preceding the end of the quarter was between 6
    and 12 percentage points above or below, respectively, the investment record
    of the Standard & Poor's 500 Composite Stock Index (the "Index") and .10%
    per annum (.025 per quarter) of the average month-end assets of the Fund if
    the Fund's investment performance for the 36 months preceding the end of the
    quarter was twelve percentage points or more above or below, respectively,
    the investment record of the Index.

      8) QUARTER ENDING OCTOBER 31, 1998. The incentive/penalty fee shall be
         calculated as the sum of 75% of the fee payable under the new rate and
         25% of the fee payable under the previous rate.
    
 
      9) QUARTER ENDING JANUARY 31, 1999. The incentive/penalty fee shall be
         calculated as the sum of 83.3% of the fee payable under the new rate
         plus 16.7% of the fee payable under the previous rate.
 
     10) QUARTER ENDING APRIL 30, 1999. The incentive/penalty fee shall be
         calculated as the sum of 91.7% of the fee payable under the new rate
         plus 8.3% of the fee payable under the previous rate.
 
     11) QUARTER ENDING JULY 31, 1999. New rate fully operable.
 
     For purposes of incentive/penalty adjustments, the investment performance
of Vanguard/Windsor Fund for any period is expressed as a percentage of
Vanguard/Windsor Fund's net asset value per share at the beginning of the
period. This percentage is equal to the sum of: (i) the change in
Vanguard/Windsor Fund's net asset value per share during the period; (ii) the
value of Vanguard/Windsor Fund's cash distributions per share having an
ex-dividend date occurring within the period; and (iii) the per share amount of
capital gains taxes paid or accrued during the period by Vanguard/Windsor Fund
for undistributed realized long-term capital gains. The investment record of the
S&P Index for any period is expressed as a percentage of the S&P Index level at
the beginning of the period. This percentage is equal to the sum of (i) the
change in the level of the S&P Index, during the period and (ii) the value,
computed consistently with the S&P Index, of cash distributions having an
ex-dividend date occurring within the period made by companies whose securities
comprise the S&P Index.
 
   
     During the fiscal years ended October 31, 1995, 1996 and 1997

VANGUARD/WINDSOR II
 
     Vanguard/Windsor II employs a "multi-manager" approach utilizing four
investment advisors.
 
BARROW, HANLEY, MEWHINNEY & STRAUSS
 
   
     Vanguard/Windsor II has entered into an investment advisory agreement dated
May 1, 1993 with Barrow, Hanley, Mewhinney & Strauss, Inc. ("BHM&S") to manage a
portion of the equity allocation of Vanguard/Windsor II (currently approximately
73%). Under this agreement, BHM&S manages the investment and reinvestment of the
designated assets and continuously reviews, supervises and administers the
investment program of Vanguard/Windsor II with respect to those assets. BHM&S
discharges its responsibilities subject to the control of the Officers and
Directors of the Company.
    
 
     BHM&S is a Texas corporation controlled by the following officers of BHM&S:
James Purdy Barrow, Principal; Bryant Miller Hanley, Jr., President, Secretary
and Treasurer; Michael Christopher Mewhinney, Principal; and John Luke Strauss,
Principal.

     Vanguard/Windsor II pays BHM&S a basic fee at the end of each fiscal
quarter, calculated by applying a quarterly rate, based on the following annual
percentage rates, to the average month-end net assets of Vanguard/Windsor II
managed by BHM&S for the quarter:

     The Fund's payments to BHM&S under the above schedule are subject to an
incentive/penalty fee arrangement which compares the performance of the Fund's
assets managed by BHM&S with the performance of the Standard & Poor's/BARRA
Value Index. This arrangement provides for the following adjustments to BHM&S's
basic fee:

                 More than 9%.................................  +0.25 X Basic Fee
</TABLE>
 
- ---------------
* For purposes of this calculation, the basic fee is calculated by applying the
  quarterly rate against average assets over the 36-month period.
 
     The BARRA Value Index includes stocks in the Standard and Poor's 500
Composite Stock Price Index with lower than average ratios of market price to
book value. These types of stocks are often referred to as "value" stocks.
 
   
     The investment performance of the portion of Vanguard/Windsor II's assets
managed by BHM&S (the "BHM&S Portfolio") for any period is expressed as a
percentage of the "BHM&S Portfolio Unit Value" at the beginning of such period.
This percentage is equal to the sum of: (i) the change in the BHM&S Portfolio
Unit Value during such period; (ii) the unit value of the Series' cash
distributions from the BHM&S Portfolio's net investment income and realized net
capital gains (whether long-term or short-term) having an ex-dividend date
occurring within such period; and (iii) the unit value of capital gains taxes
paid or accrued during such period by Vanguard/Windsor II for undistributed
realized long-term capital gains realized from the BHM&S Portfolio.
    
 
     The "BHM&S Portfolio Unit Value" will be determined by dividing the total
net assets of the BHM&S Portfolio by a given number of units. On the initial
date of the agreement, the number of units in the BHM&S Portfolio was equal to
the total shares outstanding of Vanguard/Windsor II. After such initial date, as
assets are added to or withdrawn from the BHM&S Portfolio, the number of units
of the BHM&S Portfolio will be adjusted based on the unit value of the BHM&S
Portfolio on the day such changes are executed.
 
     The investment record of the BARRA Value Index is calculated quarterly by
(i) multiplying the total return for the quarter (change in market price plus
dividends) of each stock included in the BARRA Value Index by its weighting in
the BARRA Value Index at the beginning of the quarter, and (ii) adding the
values discussed in (i). For any period, therefore, the investment record of the
BARRA Value Index will be the compounded quarterly returns of the BARRA Value
Index.
 
   
     During the fiscal years ended October 31, 1995, 1996 and 1997,
Vanguard/Windsor II paid advisory fees to BHM&S of approximately $8,514,842,
$11,475,528, and $16,925,953 before a performance adjustment of $2,495,021,
respectively.

OTHER ADVISERS
 
   
     On November 1, 1991, Vanguard/Windsor II added Equinox Capital Management
("Equinox") and Tukman Capital Management ("Tukman") to manage the investment
and reinvestment of a portion of its equity allocation (approximately 10% each).
Additionally, Vanguard's Core Management Group was added to manage approximately
7% of the Vanguard/Windsor II's equity allocation. Equinox, Tukman and
Vanguard's Core Management Group discharge their respective responsibilities
subject to the control of the Directors and Officers of the Company.
    
 
EQUINOX
 
     Equinox is a Delaware corporation controlled by the following officers of
Equinox: Ronald J. Ulrich, President and Director; Wendy D. Lee, Managing
Director; David E. Walker, Principal; Laura Starr, Vice President; Jacqueline A.
Williams, Vice President; Mark W. Watson, Vice President; and Kenneth J. Doerr,
Vice President.
 
     Under the terms of an investment advisory agreement dated August 1, 1996,
Vanguard/Windsor II pays Equinox a basic fee at the end of each fiscal quarter,
calculated by applying a quarterly rate, based on the following annual
percentage rates, to the portion of Vanguard/Windsor II's average month-end net
assets managed by Equinox for the quarter.

                 Assets in excess of $2 billion......................      .100%
</TABLE>
 
     The basic fee paid to Equinox may be increased or decreased by applying an
adjustment formula based on the investment performance of the portion of
Vanguard/Windsor II's assets managed by Equinox (the "Equinox Portfolio")
relative to the investment of the Russell 1000 Value Index. Such formula
provides for an increase or decrease in the basic fee paid to Equinox each
quarter, depending upon the Equinox Portfolio's investment performance for the
thirty-six months preceding the end of the quarter.

* For purposes of this calculation, the basic fee is calculated by applying the
  quarterly rate against average assets over the 36-month period.
 
   
     The above incentive/penalty fee will not be fully operable until the
quarter ending July 31, 1999. Until that date, a "blended fee rate" consisting
of varying percentages of (i) the performance adjustment based on the schedule
set forth above (the "new rate"), and (ii) the performance adjustment based on
the schedule set forth in Vanguard/Windsor II's previous investment advisory
agreement with Equinox (the "previous rate") shall be used as follows:
    
 
      1) QUARTER ENDING OCTOBER 31, 1996.  The incentive/penalty fee was
calculated as the sum of 8.3% of the fee payable under the new rate plus 91.7%
of the fee payable under the previous rate.
 
      2) QUARTER ENDING JANUARY 31, 1997.  The incentive/penalty fee was
calculated as the sum of 16.7% of the fee payable under the new rate plus 83.3%
of the fee payable under the previous rate.

      3) QUARTER ENDING APRIL 30, 1997.  The incentive/penalty fee was
calculated as the sum of 25% of the fee payable under the new rate plus 75% of
the fee payable under the previous rate.
    
 
   
      4) QUARTER ENDING JULY 31, 1997.  The incentive/penalty fee was calculated
as the sum of 33% of the fee payable under the new rate plus 67% of the fee
payable under the previous rate.
    
 
   
      5) QUARTER ENDING OCTOBER 31, 1997.  The incentive/penalty fee was
calculated as the sum of 41.6% of the fee payable under the new rate plus 58.4%
of the fee payable under the previous rate.
    
 
   
      6) QUARTER ENDING JANUARY 31, 1998.  The incentive/penalty fee was
calculated as the sum of 50% of the fee payable under the new rate plus 50% of
the fee payable under the previous rate.
    
 
      7) QUARTER ENDING APRIL 30, 1998.  The incentive/penalty fee shall be
calculated as the sum of 58.4% of the fee payable under the new rate plus 41.6%
of the fee payable under the previous rate.
 
      8) QUARTER ENDING JULY 31, 1998.  The incentive/penalty fee shall be
calculated as the sum of 67% of the fee payable under the new rate plus 33% of
the fee payable under the previous rate.
 
      9) QUARTER ENDING OCTOBER 31, 1998.  The incentive/penalty fee shall be
calculated as the sum of 75% of the fee payable under the new rate plus 25% of
the fee payable under the previous rate.
 
     10) QUARTER ENDING JANUARY 31, 1999.  The incentive/penalty fee shall be
calculated as the sum of 83.3% of the fee payable under the new rate plus 16.7%
of the fee payable under the previous rate.
 
     11) QUARTER ENDING APRIL 30, 1999.  The incentive/penalty fee shall be
calculated as the sum of 91.7% of the fee payable under the new rate plus 8.3%
of the fee payable under the previous rate.
 
     12) QUARTER ENDING JULY 31, 1999.  New rate fully operable.
- ---------------
The previous incentive/penalty fee structure provided that the Basic Fee be
increased or decreased by an amount equal to .05% per annum (.0125 per quarter)
of the average month-end assets if the Fund's investment performance for the 36
months preceding the end of the quarter was between 6 and 12 percentage points
above or below, respectively, the investment record of the Standard & Poor's 500
Composite Stock Index (the "Index") and .10% per annum (.025 per quarter) of the
average month-end assets of the Fund if the Fund's investment performance for
the 36 months preceding the end of the quarter was twelve percentage points or
more above or below, respectively, the investment record of the Index.
 
     The investment performance of the Equinox Portfolio for any period is
expressed as a percentage of the "Equinox Portfolio Unit Value" at the beginning
of such period. This percentage is equal to the sum of: (i) the change in the
Equinox Portfolio Unit Value during such period; (ii) the unit value of
Vanguard/Windsor II's cash distributions from the Equinox Portfolio net
investment income and realized net capital gains (whether long-term or
short-term) having an ex-dividend date occurring within such period; and (iii)
the unit value of capital gains taxes paid or accrued during such period by
Vanguard/Windsor II for undistributed realized long-term capital gains realized
from the Equinox Portfolio.
 
     The "Equinox Portfolio Unit Value" will be determined by dividing the total
net assets of the Equinox Portfolio by a given number of units. On the initial
date of the agreement, the number of units in the Equinox Portfolio was equal to
the total shares outstanding of Vanguard/Windsor II. After such initial date, as
assets are added to or withdrawn from the Equinox Portfolio, the number of units
of the Equinox Portfolio will be adjusted based on the unit value of the Equinox
Portfolio on the day such changes are executed.
 
     The investment record of the Russell 1000 Value Index will be calculated
quarterly by (i) multiplying the total return for the quarter (change in the
market price plus dividends) of each stock included in the Russell 1000 Value
Index by its weighting in the Russell 1000 Value Index at the beginning of the
quarter, and (ii) adding the values discussed in (i). For any period, therefore,
the investment record of the Russell 1000 Value Index will be the compounded
quarterly returns of the Russell 1000 Value Index.
 
   
     During the fiscal years ended October 31, 1995, 1996 and 1997,
Vanguard/Windsor II paid advisory fees to Equinox of approximately $1,681,435,
$1,980,458 before a performance adjustment of $4,747, and $2,791,342 before a
performance adjustment of $408,295, respectively. These fees were paid under a
previous fee schedule that provided for a higher rate of fees.

TUKMAN
 
     Tukman is a Delaware corporation controlled by the following officers of
Tukman: Melvin T. Tukman, President and Director, and Daniel L. Grossman, Vice
President.
 
     Under the terms of an investment advisory agreement dated November 1, 1991,
the Fund pays Tukman a basic fee at the end of each fiscal quarter, calculated
by applying a quarterly rate, based on the following annual percentage rates, to
the average month-end assets of the portion of Vanguard/Windsor II's assets
managed by Tukman:

     The Fund's payments to Tukman under the above schedule are subject to an
incentive/penalty fee arrangement which compares the performance of the Fund's
assets managed by Tukman with the performance of the Standard & Poor's 500
Composite Stock Price Index. This arrangement provides for the following
adjustments to Tukman's basic fee:

</TABLE>

* For purposes of this calculation, the basic fee is calculated by applying the
  quarterly rate against average assets over the 36-month period.
 
   
     The investment performance of the portion of Vanguard/Windsor II's assets
managed by Tukman (the "Tukman Portfolio") for any period is expressed as a
percentage of the "Tukman Portfolio Unit Value" at the beginning of such period.
The percentage is equal to the sum of: (i) the change in the Tukman Portfolio
Unit Value during such period; (ii) the unit value of Vanguard/Windsor II's cash
distributions from the Tukman Portfolio net investment income and realized net
capital gains (whether long-term or short-term) having an ex-dividend date
occurring within such period; and (iii) the unit value of capital gains taxes
paid or accrued during such period by Vanguard/Windsor II for undistributed
realized long-term capital gains realized from the Tukman Portfolio.
    
 
     The "Tukman Portfolio Unit Value" will be determined by dividing the total
net assets of the Tukman Portfolio by a given number of units. On the initial
date of the agreement, the number of units in the Tukman Portfolio was equal to
the total shares outstanding of Vanguard/Windsor II. After such initial date, as
assets are added to or withdrawn from the Tukman Portfolio, the number of units
of the Tukman Portfolio will be adjusted based on the unit value of the Tukman
Portfolio on the day such changes are executed.
 
     The investment record of the S&P 500 will be calculated quarterly by (i)
multiplying the total return for the quarter (change in market price plus
dividends) of each stock included in the S&P 500 by its weighting in the S&P 500
at the beginning of the quarter, and (ii) adding the values discussed in (i).
For any period, therefore, the investment record of the S&P 500 will be the
compounded quarterly returns of the S&P 500.
 
   
     During the fiscal years ended October 31, 1995, 1996 and 1997,
Vanguard/Windsor II paid advisory fees to Tukman of approximately $2,184,838,
$2,699,458, before a performance adjustment of $930,724, and $3,622,904 before a
performance adjustment of $785,658, respectively.

VANGUARD'S CORE MANAGEMENT GROUP
 
   
     Since November 1, 1991, Vanguard's Core Management Group has provided
investment advisory services on an at-cost basis with respect to a portion of
Vanguard/Windsor II's equity allocation (currently approximately 7%). The Core
Management Group also provides investment advisory services to several Vanguard
Funds, including Vanguard Index Trust, Vanguard Balanced Index Fund, Vanguard
Horizon Fund, Vanguard International Equity Index Fund, Vanguard REIT Index
Portfolio, Vanguard Institutional Index Fund, Total International Portfolio of
Vanguard STAR Fund, several indexed separate accounts as well as a portion of
Vanguard/Morgan Growth Fund, and Vanguard Explorer Fund's assets. The
quantitative approach used by Vanguard's Core Management Department is designed
to generate highly predictable results relative to a benchmark of large and
medium capitalization "value" stocks. A portfolio is constructed from
attractively priced "value" stocks using an optimizer to assure that the
characteristics of the portfolio are similar to that of the benchmark. The Core
Management Group is supervised by the Officers of the Company.
    
 
DURATION AND TERMINATION OF INVESTMENT ADVISORY AGREEMENTS
 
   
     Vanguard/Windsor Fund's present agreement with WMC continues in effect
until July 31, 1998. Vanguard/ Windsor II's present agreements with BHM&S,
Equinox and Tukman continue in effect until April 30, 1998, July 31, 1998 and
October 31, 1998, respectively. Each agreement is renewable for successive
one-year periods if specifically approved by a vote of the Company's Board of
Directors at a meeting called for the purpose of considering such approval. The
Board's approval must include the affirmative votes of a majority of the
Directors who are neither parties to the contract or "interested persons" of
such parties (as defined in the Investment Company Act of 1940). In addition,
the question of continuing an investment advisory agreement may be presented to
shareholders. In such an event, the agreement would be continued only if
approved by the affirmative vote of a majority of the outstanding shares of the
Series to which the agreement related.
    
 
   
     Each investment advisory agreement is automatically terminated if assigned,
and may be terminated without penalty at any time (1) by majority vote of either
the Board of Directors or the Company's outstanding shares upon 60 days' written
notice to the adviser, or (2) by the adviser upon 90 days' written notice to the
Company.
    
 
     The Company's Board of Directors may, without the approval of shareholders,
provide for:
 
     (A) The employment of a new investment adviser pursuant to the terms of a
         new advisory agreement, either as a replacement for an existing adviser
         or as an additional adviser;
 
     (B) A change in the terms of an advisory agreement; or
 
     (C) The continued employment of an existing adviser, on the same advisory
         contract terms, where a contract has been assigned because of a change
         in control of the adviser.
 
     Any such change will be made upon not less than 30 days' prior written
notice to shareholders, which shall include the information concerning the
adviser that would have normally been included in a proxy statement.
 
MORE INFORMATION ON ADVISERS' INCENTIVE/PENALTY FEES
 
   
     In April 1972, the Commission issued Release No. 7113 (the "Release") under
the Investment Company Act of 1940 to call the attention of directors and
investment advisers to certain factors which must be considered in connection
with investment company incentive fee arrangements. One of these factors is to
"avoid basing significant fee adjustments upon random or insignificant
differences" between the investment performance of a fund and that of the
particular index with which it is being compared. The Release provides that
"preliminary studies (of the SEC staff) indicate that as a 'rule of thumb' the
performance difference should be at least P10 percentage points" annually before
the maximum performance adjustment may be made. However, the Release also states
that "because of the preliminary nature of these studies, the Commission is not
recommending, at this time, that any particular performance difference exist
before the maximum fee adjustment may be made." The Release concludes that the
directors of a fund "should satisfy
    
 
                                      B-19
<PAGE>   114
 
   
themselves that the maximum performance adjustment will be made only for
performance differences that can reasonably be considered significant." The
Board of Directors has fully considered the Release and believes that the
performance adjustments as included in the agreements with WMC, BHM&S, Equinox
and Tukman are entirely appropriate, although not within the P10 percentage
points per year range suggested in the Release. Under the Company's investment
advisory agreements, the maximum performance adjustments are made at a
difference of P12 and P9 percentage points from the performance of the
respective index over a thirty-six month period, which would effectively be the
equivalent of approximately P4 and P3 percentage points difference per year.
    
 
                             PORTFOLIO TRANSACTIONS
 
     WMC, BHM&S, Equinox, Tukman and Vanguard are authorized to (with the
approval of the Board of Directors) select the brokers or dealers that will
execute the purchases and sales of portfolio securities for the respective
series of the Company. The investment advisory agreements direct the advisers to
use their best efforts to obtain the best available price and most favorable
execution as to all transactions. Each investment adviser has undertaken to
execute each investment transaction at a price and commission which provides the
most favorable total cost or proceeds reasonably obtainable under the
circumstances.
 
     In placing portfolio transactions, each investment adviser will use 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 will be 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 may
be given to those brokers which supply investment research and statistical
information and provide other services in addition to execution services to the
series and/or the investment adviser. Each investment adviser considers such
information useful in the performance of its obligations under the agreement,
but is unable to determine the amount by which such services may reduce its
expenses.
 
     The investment advisory agreements also incorporate the concepts of Section
28(e) of the Securities Exchange Act of 1934 by providing that, subject to the
approval of the Board of Directors, each investment adviser may cause the series
to pay a broker-dealer which furnishes brokerage and research services a higher
commission than that which might be charged by another broker-dealer for
effecting the same transaction; provided that such commission is deemed
reasonable in terms of either that particular transaction or the overall
responsibilities of the adviser to the Company and the other Funds in the Group.
 
     Currently, it is the Company's policy that each investment adviser may at
times pay higher commissions in recognition of brokerage services felt necessary
for the achievement of better execution of certain securities transactions that
otherwise might not be available. An investment adviser will only pay such
higher commissions if it believes this to be in the best interest of the series.
Some brokers or dealers who may receive such higher commissions in recognition
of brokerage services related to execution of securities transactions are also
providers of research information to an investment adviser and/or the Company.
However, the investment advisers have informed the Company that they will not
pay higher commission rates specifically for the purpose of obtaining research
services.
 
     Since the Company does not market its shares through intermediary brokers
or dealers, it is not the Company's practice to allocate brokerage or principal
business on the basis of sales of its shares which may be through such firms.
However, the Company may place portfolio orders with qualified broker-dealers
who recommend shares of the Company to other clients, or who act as agent in the
purchase of the Company's shares for their clients, and may, when a number of
brokers and dealers can provide comparable best price and execution on a
particular transaction, consider the sale of the Company's shares by a broker or
dealer in selecting among qualified broker-dealers.
 
   
     During the fiscal years ended October 31, 1995, 1996 and 1997 the Company
paid $17,775,409, $25,321,530, and $45,284,493 in brokerage commissions,
respectively.
    
 
                                      B-20
<PAGE>   115
 
     Some securities considered for investment by a series of the Company may
also be appropriate for the other series and for other Funds and/or clients
served by the investment adviser. If purchase or sale of securities consistent
with the investment policies of the series and one or more of these other Funds
or clients served by the investment adviser are considered at or about the same
time, transactions in such securities will be allocated among the several Funds
and clients in a manner deemed equitable by the investment adviser.

                    DESCRIPTION OF SHARES AND VOTING RIGHTS
 
   
     The Company was originally organized as a corporation in 1959. On January
2, 1985, the Company was reorganized into a Pennsylvania business trust. The
Company was reorganized as a Maryland corporation on December 30, 1985. The
Amended and Restated Articles of Incorporation permit the Directors to issue
2,700,000,000 shares of common stock, with one cent par value. The Board of
Directors has the power to designate one or more classes ("series") of shares of
common stock and to classify or reclassify any unissued shares with respect to
such series. Currently the Company is offering shares of two series.
    
 
     The shares of each series are fully paid and non-assessable, and have no
preference as to conversion, exchange, dividends, retirement or other features.
The shares of each series have no pre-emptive rights. Such shares have
non-cumulative voting rights, which means that the holders of more than 50% of
the shares voting for the election of Directors can elect 100% of the Directors
if they choose to do so. A shareholder is entitled to one vote for each full
share held (and a fractional vote for each fractional share held), then standing
in his name on the books of the Company. On any matter submitted to a vote of
shareholders, all shares of the Company then issued and outstanding and entitled
to vote, irrespective of the series, shall be voted in the aggregate and not by
series except (i) when required by the Investment Company Act of 1940, shares
shall be voted by individual series; and (ii) when the matter does not affect
any interest of a particular series, then only shareholders of the affected
series shall be entitled to vote thereon.
