INVESTMENT OBJECTIVE AND POLICIES

Vanguard/Morgan Growth Fund, Inc. (the "Fund") is an open-end diversified
investment management company, or mutual fund.

   The Fund seeks to provide long-term capital growth by investing mainly in
equity securities of large, established companies that have strong sales and
earnings records or have performed well during certain market cycles. The Fund
also invests in stocks of smaller companies that offer good expansion prospects.

   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

The 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 containing more information about the Fund
is, by reference, part of this prospectus and may be obtained without charge by
writing to Vanguard or by calling our Investor Information Department at
1-800-662-7447.

WHY READING THIS PROSPECTUS IS IMPORTANT

This prospectus explains the objective, risks, and strategies of Vanguard/Morgan
Growth 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 or any state securities commission, nor has the Securities
and Exchange Commission or any state commission passed upon the accuracy or
adequacy of this prospectus. Any representation to the contrary is a criminal
offense.

FUND PROFILE                                         Vanguard/Morgan Growth Fund

WHO SHOULD INVEST (page 4)

- -   Investors seeking a growth 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.

WHO SHOULD NOT INVEST

- -   Investors seeking current dividend income.

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

RISKS OF THE FUND  (pages 4 - 7)

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, as a growth stock fund, to objective risk (the
chance that returns from growth stocks will trail returns from the overall stock
market).

DIVIDENDS AND CAPITAL GAINS (page 10) 
Paid annually in December.

In evaluating past performance, remember that it is not indicative of future
performance and that returns from stocks before adjusting for inflation were
relatively high during the periods shown. Performance figures include the
reinvestment of any dividends and capital gains distributions. The returns shown
are net of expenses, but they do not reflect income taxes an 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/Morgan Growth Fund's expense ratio in fiscal year 1995 was
0.49%, or $4.90 per $1,000 of average net assets. The average growth equity
mutual fund had expenses in 1995 of 1.36%, or $13.60 per $1,000 of average net
assets, according to Lipper Analytical Services, Inc., 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 maintaining accounts, administering the Fund, providing shareholder
services, and other activities. The expenses shown in the table are for the
fiscal year ended December 31, 1995.

   From time to time, the Vanguard Funds advertise yield and total return
figures. Yield is an historical measure of dividend income, and total return is
a measure of past dividend income (assuming that it has been reinvested) plus
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 1995 with a net asset value (price) of $11.36 per share.
During the year, the Fund earned $0.15 per share from investment income
(interest and dividends) and $3.89 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 $4.04 per share, $1.31 was returned to
shareholders in the form of distributions ($0.15 in dividends, $1.16 in capital
gains). The earnings ($4.04 per share) less distributions ($1.31 per share)
resulted in a share price of $14.09 at the end of the year, an increase of $2.73
per share (from $11.36 at the beginning of the period to $14.09 at the end of
the period). Assuming that the shareholder had reinvested the distribution in
the purchase of more shares, total return from the Fund was 35.98% for the year.

   As of December 31, 1995, the Fund had $1.47 billion in net assets; an expense
ratio of 0.49% ($4.90 per $1,000 of net assets); and net investment income
amounting to 1.10% of its average net assets. It sold and replaced securities
valued at 76% of its total net assets.

                                PLAIN TALK ABOUT
                          GROWTH FUNDS AND VALUE FUNDS

Growth investing and value investing are two styles employed by stock fund
managers. Growth funds generally 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 funds generally emphasize
companies that, considering their assets and earnings history, are attractively
priced; these companies often pay regular dividend income to shareholders.
Growth and value stocks have, in the past, produced similar long-term returns,
though each has periods when it outperforms the other. In general, growth funds
appeal to investors who will accept more volatility in hope of a greater
increase in share price, while 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.

                                PLAIN TALK ABOUT
                           INVESTING FOR THE LONG TERM

Vanguard/Morgan Growth 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 will face as an investor in
Vanguard/Morgan Growth 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
Vanguard/Morgan Growth Fund, you should also take into account your personal
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, will confront.
================================================================================

THE FUND'S OBJECTIVE

Vanguard/Morgan Growth Fund seeks to provide long-term growth of capital. This
objective is fundamental, which means that it 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

The Fund may be a suitable investment for you if:

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

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

- -  You are seeking a fund that invests in growth companies representing a wide
   variety of industries.

- -  You are not looking for current 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 STRATEGIES

This section explains how Vanguard/Morgan Growth Fund's investment advisers
pursue the objective of long-term capital growth. It also explains several
important risks -- market risk, objective risk, manager risk, and country risk
- -- faced by investors in the Fund. Unlike the Fund's investment objective, the
advisers' investment strategies are not fundamental and can be changed by the
Fund's Board of Directors without shareholder approval. However, before making
any important change in its policies, the Fund will give shareholders 30-days
notice, in writing.

MARKET EXPOSURE

The Fund is a growth fund that invests mainly in large-capitalization common
stocks. The Fund also includes stocks of smaller companies that -- even though
they may not have a long history of growth -- one of the Fund's advisers finds
attractive. All stocks are chosen for their above-average earnings growth
potential. At times, the Fund may also invest in securities that are convertible
into common stocks.

[FLAG]THE PORTFOLIO 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 best and worst 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 do not generate the costs.
Therefore, the Fund discourages short-term trading by, among other things,
limiting the number of exchanges it permits.

                                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 an average total market value exceeding $5 billion. Mid-cap funds
hold stocks of companies with an average market value between $750 million and
$5 billion. Small-cap funds hold stocks of companies with an average market
value of less than $750 million.

<PAGE>   10
                                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 diversification is the percentage of total net assets represented by its
ten largest holdings. The average U.S. equity mutual fund has about 25% of its
assets invested in its ten largest holdings, while some less-diversified mutual
funds have more than 50% 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 1995. For example, while the average return on stocks for all of the
5-year periods was +10.3%, returns for these 5-year periods ranged from a -12.5%
average (from 1928 through 1932), to +23.9% (from 1951 through 1955). 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 Morgan Growth Fund does not hold the same securities held in
the Standard & Poor's 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 GROWTH STOCKS WILL TRAIL RETURNS FROM THE OVERALL STOCK
            MARKET. AS A GROUP, GROWTH STOCKS TEND TO GO THROUGH CYCLES OF
            RELATIVE UNDERPERFORMANCE AND OUTPERFORMANCE IN COMPARISON TO COMMON
            STOCKS IN GENERAL. THESE PERIODS HAVE, IN THE PAST, LASTED FOR AS
            LONG AS SEVERAL YEARS.

SECURITY SELECTION

In an attempt to ensure broad diversification, Morgan Growth Fund employs four
investment advisers, each of whom independently chooses and maintains a
portfolio of common stocks for the Fund.

   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 markets and
the economy in general.

   Each adviser is responsible for investing 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.

   Wellington Management Company (WMC), which is responsible for about 40% of
the Fund's assets, uses traditional methods of stock selection -- company
research and analysis -- to identify companies that it feels have above-average
growth prospects, particularly those in industries undergoing change.

   Husic Capital Management (Husic), which manages about 14% of the Fund's
assets, also employs traditional stock selection methods, but with a difference.
Husic evaluates stocks based on several key factors, such as how well a
company's stock performs as a result of changes within the company or its
industry, or how actual company performance (as reflected in, for example, sales
growth and new product introduction) compares to Husic's own forecast for the
company.

   The remaining two advisers, Franklin Portfolio Associates Trust (FPA) and
Vanguard Core Management Group, employ a "quantitative" investment approach. In
other words, they use computer techniques to track -- and, if possible,
outperform -- a specific market standard. For Morgan Growth Fund, this market
standard is the Growth Fund Stock Index, which is made up of the nation's 50
largest growth funds. FPA manages about 35% and the Core Management Group
handles about 11% of the Fund's assets.

   Keep in mind that, because the makeup of the Fund changes daily, 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 INVESTMENT 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 50%. (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 common stocks of growth companies, the Fund may follow a
number of investment policies to achieve its objective.

   The Fund may invest in securities of companies based outside the United
States. These securities may be traded in U.S. or foreign markets.

[FLAG]THE FUND IS SUBJECT TO COUNTRY RISK, WHICH 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.

   The Fund may also invest in derivatives.

[FLAG]ALTHOUGH IT HAS NOT DONE SO IN THE PAST, THE FUND RESERVES THE RIGHT TO
      INVEST, TO A LIMITED EXTENT, IN STOCK FUTURES AND OPTIONS CONTRACTS, WHICH
      ARE TRADITIONAL TYPES OF DERIVATIVES.

                                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. 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
actively managed fund investing in common stocks is 75%.

                                PLAIN TALK ABOUT
                      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 countries are not subject to the same
accounting, auditing, and financial reporting standards and practices as U.S.
companies, and may not be as liquid as 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 about foreign investment risk, see the Statement of Additional
Information.

                                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.

   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. This 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 short-term cash-equivalent securities in the amount of
the obligation underlying the futures or options contract. Only a limited
percentage of the Fund's assets -- no more than 20% of total assets -- may be
committed to such contracts.

   The reasons for which the Fund may use futures and options are:

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

- -  To make it easier to trade.

- -  To reduce costs by buying futures instead of actual stocks when futures are
   cheaper.

   The Portfolio will usually hold only a small percentage of its assets in cash
reserves, although if the investment advisers believe that market conditions
warrant a temporary defensive measure, the Portfolio may hold cash reserves
without limit.

INVESTMENT LIMITATIONS

To reduce risk and maintain diversification, the Fund has adopted limits on some
of its investment policies. Specifically, the Fund will not:

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

- -  Borrow money, except for the purpose of meeting shareholder requests to
   redeem shares.

   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 securities of any company.

   The limitations listed in this prospectus and in the Statement of Additional
Information are fundamental and may be changed only by approval of a majority of
the Fund's shareholders.

INVESTMENT PERFORMANCE

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

         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 Index. The chart
does not make any allowance for Federal, state, or local income taxes that
shareholders must pay on a current basis.

         In weighing these performance figures, note that it has been in
operation since December 31, 1968, and that until April 24, 1990, Wellington
Management Company was the Fund's only investment adviser (Franklin Portfolio
Associates was added as an adviser in 1990; Husic Capital Management and
Vanguard Core Management Group were added in 1993).

SHARE PRICE

The Fund's share price, called its net asset value, is calculated each business
day after the close of regular trading (generally 4:00 p.m. Eastern time) of the
New York Stock Exchange. Net asset value per share is computed by adding up the
total value of the Fund's investments and other assets, subtracting any of its
liabilities, or debts, and then dividing by the number of Fund shares
outstanding:

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

         Daily net asset value, or NAV, 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 Group. Different newspapers
use different abbreviations of the Fund's name, but the most common is MORG.

                                PLAIN TALK ABOUT
                                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.

                                PLAIN TALK ABOUT
                                  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 the 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. The capital gains are either short-term or long-term depending on
whether the fund held the securities for less than or more than one year.


                                PLAIN TALK ABOUT
                               "BUYING A DIVIDEND"

Unless you are investing 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
the dividends in more shares. To avoid "buying a dividend," check a fund's
distribution schedule before you invest.

DIVIDENDS, CAPITAL GAINS, AND TAXES

Each December, the Fund distributes to shareholders virtually all of its income
from interest and dividends, as well as any capital gains realized from the sale
of securities. You can receive distributions of income or capital gains in cash,
or you may have them automatically reinvested in more shares of the Fund. In
either case, distributions of dividends and capital gains that are declared in
December -- even if paid to you in January -- are taxed as if they had been paid
to you in December. Vanguard will process your dividend distribution and send
you a statement each year 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. Both
         dividends and capital gains distributions are taxable to you whether
         received in cash or reinvested in additional shares. 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 byproducts of the
         ordinary investment activities of the Fund. Consequently, distributions
         may vary considerably from year to year.

- -        If you sell or exchange shares of the Fund, 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 own tax adviser about the tax
consequences of an investment in the Fund.

THE FUND AND VANGUARD

The Fund is a member of The Vanguard Group, a family of more than 30 investment
companies with more than 90 distinct investment portfolios and total net assets
of more than $190 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.

                              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, 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.

         Vanguard Core Management Group, P.O. Box 2600, Valley Forge, PA 19482,
was responsible for 10% of Morgan Growth Fund's assets as of December 31, 1995.
The Group provides investment advisory services to several Vanguard Funds,
managing more than $33 billion in total assets as of year end 1995. Vanguard
Core Management Group provides advisory services to the Fund on an at-cost
basis.

         Any Fund assets held in cash (which, as of December 31, 1995, equaled
5% of the Fund's assets) are managed, at no cost to the Fund, by The Vanguard
Group, Inc.

         For the year ended December 31, 1995, the total fee paid by
Vanguard/Morgan Growth Fund to its advisers was $1.77 million, which included a
base fee of $2.39 million and a decrease, based on adviser performance, of
$621,000.

         The fee agreement with each adviser authorizes them to choose brokers
or dealers to handle the purchase and sale of the Fund's securities, and directs
them to get the best available price and most favorable execution from these
brokers with respect to all transactions.

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

GENERAL INFORMATION

Vanguard/Morgan Growth Fund is organized under the laws of the State of
Maryland. Shareholders of the 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. Although the Fund does not usually hold an annual meeting,
shareholders may request one under certain circumstances, which are described in
the Statement of Additional Information.

  Shares purchased by check or Vanguard Fund Express can be redeemed at any
  time. However, while your redemption request will be processed as soon as it
  is received, your redemption proceeds will not be available until payment for
  your purchase is collected, which may take up to ten days.

   It is important that you call Vanguard before you invest a large dollar
amount by wire or check. Vanguard must consider the interests of all Fund
shareholders and so reserves the right to delay or refuse any purchase that may
disrupt the Fund's operation or performance.

REDEEMING SHARES

  IMPORTANT TAX NOTE: Any sale or exchange of shares in a non-retirement 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 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:

   /X/  Fund name.
   /X/  10-digit account number.
   /X/  Name and address exactly as registered on that account.
   /X/  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. However, if we do not follow
these or other reasonable procedures, Vanguard may be liable for any losses
resulting from unauthorized or fraudulent transactions.

REDEEMING SHARES (continued)

HOW TO SELL SHARES

You may withdraw any part of your account, at any time, by selling shares;
however, the Fund reserves the right to close any non-retirement or UGMA/UTMA
account whose balance falls below the minimum initial investment. The Fund will
deduct a $10 annual fee if your non- retirement account balance falls below
$2,500 or if your UGMA/UTMA account balance falls below $500. The fee is waived
if your total Vanguard Fund account assets are $50,000 or more.

   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:

   /X/  Fund name and account number.
   /X/  Amount of the transaction (in dollars or shares).
   /X/  Signatures of all owners exactly as registered on the account.
   /X/  Signature guarantees (if required).
   /X/  Any supporting legal documentation that may be required.
   /X/  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 4:00 p.m. Eastern time) are processed at the next
business day's net asset value.

  Some written requests require a signature guarantee from a bank, broker, or
  other acceptable 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 every effort will be made 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 has established a policy of
limiting 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 large enough to have a negative impact on the Fund or a series
of movements between Vanguard Funds.

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

INVESTMENT OBJECTIVE AND POLICIES

Vanguard/Morgan Growth Fund, Inc. (the "Fund") is an open-end diversified
investment management company, or mutual fund.

     The Fund seeks to provide long-term capital growth by investing mainly in
equity securities of large, established companies that have strong sales and
earnings records or have performed well during certain market cycles. The Fund
also invests in stocks of smaller companies that offer good expansion prospects.

     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

The 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. Another version -- for investors
who would like to open a personal investment account --can be obtained by
calling Vanguard at 1-800-662-7447.

ADDITIONAL INFORMATION ABOUT THE FUND

A Statement of Additional Information 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).

WHY READING THIS PROSPECTUS IS IMPORTANT

This prospectus explains the objective, risks, and strategies of Vanguard/Morgan
Growth 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 your needs.
We suggest that you keep it for future reference.


These securities have not been approved or disapproved by the Securities and
Exchange Commission or any state securities commission, nor has the Securities
and Exchange Commission or any state commission passed upon the accuracy or
adequacy of this prospectus. Any representation to the contrary is a criminal
offense.

WHO SHOULD INVEST (page 4)

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

     five years.

WHO SHOULD NOT INVEST

RISKS OF THE FUND (pages 4 - 7)

manager risk (the chance that poor security selection will cause it to lag the
stock market as a whole) and, as a growth stock fund, to objective risk (the
chance that returns from growth stocks will trail returns from the overall stock
market).

DIVIDENDS AND CAPITAL GAINS (page 10)

Paid annually in December. In participant accounts, all distributions are
automatically reinvested.

INVESTMENT ADVISERS (page 10)

The Fund employs a multi-adviser approach:

In evaluating past performance, remember that it is not indicative of future
performance and that returns from stocks before adjusting for inflation were
relatively high during the periods shown. Performance figures include the
reinvestment of any dividends and capital gains distributions. The returns shown
are net of expenses, but they do not reflect income taxes an 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/Morgan Growth Fund's expense ratio in fiscal year 1995 was
0.49%, or $4.90 per $1,000 of average net assets. The average growth equity
mutual fund had expenses in 1995 of 1.36%, or $13.60 per $1,000 of average net
assets, according to Upper Analytical Services, Inc., 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:

</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 maintaining accounts, administering the Fund, providing shareholder
services, and other activities. The expenses shown in the table are for the
fiscal year ended December 31, 1995.

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

*Beginning in fiscal year 1995, this figure does not include expense reductions
from directed brokerage arrangements. The Ratio of Net Expenses to Average Net
Assets was 0.48%.

     From time to time, the Vanguard Funds advertise yield and total return
figures. Yield is an historical measure of dividend income, and total return is
a measure of past dividend income (assuming that it has been reinvested) plus
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 1995 with a net asset value (price) of $11.36 per
share. During the year, the Fund earned $0.15 per share from investment income
(interest and dividends) and $3.89 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 $4.04 per share, $1.31 was returned to
shareholders in the form of distributions ($0.15 in dividends, $1.16 in capital
gains). The earnings ($4.04 per share) less distributions ($1.31 per share)
resulted in a share price of $14.09 at the end of the year, an increase of $2.73
per share (from $11.36 at the beginning of the period to $14.09 at the end of
the period). Assuming that the shareholder had reinvested the distribution in
the purchase of more shares, total return from the Fund was 35.98% for the year.

     As of December 31, 1995, the Fund had $1.47 billion in net assets; an
expense ratio of 0.49% ($4.90 per $1,000 of net assets); and net investment
income amounting to 1.10% of its average net assets. It sold and replaced
securities valued at 76% of its total net assets.

                                 AND VALUE FUNDS

Growth investing and value investing are two styles employed by stock fund
managers. Growth funds generally 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 funds generally emphasize
companies that, considering their assets and earnings history, are attractively
priced; these companies often pay regular dividend income to shareholders.
Growth and value stocks have, in the past, produced similar long-term returns,
though each has periods when it outperforms the other. In general, growth funds
appeal to investors who will accept more volatility in hope of a greater
increase in share price, while 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.

                           INVESTING FOR THE LONG TERM

Vanguard/Morgan Growth 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 will face as an investor in
Vanguard/Morgan Growth 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
Vanguard/Morgan Growth Fund, you should also take into account your personal
tolerance for the daily fluctuations of the stock market.

     Look for this "warning flag" symbol ["warning 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, will confront.

THE FUND'S OBJECTIVE

Vanguard/Morgan Growth Fund seeks to provide long-term growth of capital. This
objective is fundamental, which means that it cannot be changed unless a
majority of shareholders vote to do so.

["warning flag" symbol] 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

The Fund may be a suitable investment for you if:

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

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

- -    You are seeking a fund that invests in growth companies representing a wide
     variety of industries.

- -    You are not looking for 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. If you own shares of the 


                                       4
<PAGE>   33
     Fund as an investment option in an employer-sponsored retirement or savings
     plan, your plan dictates the rules governing exchanges. Contact your plan
     administrator for details.

- -    There is a limit on the number of times you can exchange into or out of the
     Fund.

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

INVESTMENT STRATEGIES

This section explains how Vanguard/Morgan Growth Fund's investment advisers
pursue the objective of long-term capital growth. It also explains several
important risks -- market risk, objective risk, manager risk, and country risk
- -- faced by investors in the Fund. Unlike the Fund's investment objective, the
advisers' investment strategies are not fundamental and can be changed by the
Fund's Board of Directors without shareholder approval. However, before making
any important change in its policies, the Fund will give shareholders 30-days
notice, in writing.

MARKET EXPOSURE

The Fund is a growth fund that invests mainly in large-capitalization common
stocks. The Fund also includes stocks of smaller companies that -- even though
they may not have a long history of growth -- one of the Fund's advisers finds
attractive. All stocks are chosen for their above-average earnings growth
potential. At times, the Fund may also invest in securities that are convertible
into common stocks.

["warning flag" symbol]   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 best and worst 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 do not generate the costs.
Therefore, the Fund tries to discourage short-term trading by 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 an average total market value exceeding $5 billion. Mid-cap funds
hold stocks of companies with an average market value between $750 million and
$5 billion. Small-cap funds hold stocks of companies with an average market
value of less than $750 million.

                            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 diversification is the percentage of total net assets represented by its
ten largest holdings. The average U.S. equity mutual fund has about 25% of its
assets invested in its ten largest holdings, while some less-diversified mutual
funds have more than 50% 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 1995. For example, while the average return on stocks for all of the
5-year periods was +10.3%, returns for these 5-year periods ranged from a -
12.5% average (from 1928 through 1932), to +23.9% (from 1951 through 1955).
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 Morgan Growth Fund does not hold the same securities held
in the Standard & Poor's 500 Index or any other market index, the performance of
the Fund will not mirror the returns of any particular index.

["warning flag" symbol]   THE FUND IS SUBJECT TO OBJECTIVE RISK, WHICH IS THE 
                          POSSIBILITY THAT RETURNS FROM GROWTH STOCKS WILL TRAIL
                          RETURNS FROM THE OVERALL STOCK MARKET. AS A GROUP,
                          GROWTH STOCKS TEND TO GO THROUGH CYCLES OF RELATIVE
                          UNDERPERFORMANCE AND OUTPERFORMANCE IN COMPARISON TO
                          COMMON STOCKS IN GENERAL. THESE PERIODS HAVE, IN THE
                          PAST, LASTED FOR AS LONG AS SEVERAL YEARS.

SECURITY SELECTION

In an attempt to ensure broad diversification, Morgan Growth Fund employs four
investment advisers, each of whom independently chooses and maintains a
portfolio of common stocks for the Fund.

     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 markets and
the economy in general.

     Each adviser is responsible for investing 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.

     Wellington Management Company (WMC), which is responsible for about 40% of
the Fund's assets, uses traditional methods of stock selection -- company
research and analysis -- to identify companies that it feels have above-average
growth prospects, particularly those in industries undergoing change.

     Husic Capital Management (Husic), which manages about 14% of the Fund's
assets, also employs traditional stock selection methods, but with a difference.
Husic evaluates stocks based on several key factors, such as how well a
company's stock performs as a result of changes within the company or its
industry, or how actual company performance (as reflected in, for example, sales
growth and new product introduction) compares to Husic's own forecast for the
company.

     The remaining two advisers, Franklin Portfolio Associates Trust (FPA) and
Vanguard Core Management Group, employ a "quantitative" investment approach. In
other words, they use computer techniques to track --and, if possible,
outperform -- a specific market standard. For Morgan Growth Fund, this market
standard is the Growth Fund Stock Index, which is made up of the nation's 50
largest growth funds. FPA manages about 35% and the Core Management Group
handles about 11% of the Fund's assets.

                          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 50%. (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 common stocks of growth companies, the Fund may follow a
number of investment policies to achieve its objective.

     The Fund may invest in securities of companies based outside the United
States. These securities may be traded in U.S. or foreign markets.


["warning flag" symbol]   THE FUND IS SUBJECT TO COUNTRY RISK, WHICH IS THE

                     The Fund may also invest in derivatives.

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 actively managed
fund investing in common stocks is 75%.

                             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 countries are not subject to the same
accounting, auditing, and financial reporting standards and practices as U.S.
companies, and may not be as liquid as 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 about foreign investment risk, 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.


     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. This 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 short-term cash-equivalent securities in the amount of
the obligation underlying the futures or options contract. Only a limited
percentage of the Fund's assets -- no more than 20% of total assets -- may be
committed to such contracts.

     The reasons for which the Fund may use futures and options are:

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

- -    To make it easier to trade.

- -    To reduce costs by buying futures instead of actual stocks when futures are
     cheaper.

     The Portfolio will usually hold only a small percentage of its assets in
cash reserves, although if the investment advisers believe that market
conditions warrant a temporary defensive measure, the Portfolio may hold cash
reserves without limit.

INVESTMENT LIMITATIONS

To reduce risk and maintain diversification, the Fund has adopted limits on some
of its investment policies. Specifically, the Fund will not:

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

- -    Borrow money, except for the purpose of meeting shareholder requests to
     redeem shares. With respect to 75% of its assets, this Fund will not:

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

INVESTMENT PERFORMANCE

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

     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 Index. The chart does not
make any allowance 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 December 31, 1968, and that until April 24, 1990, Wellington
Management Company was the Fund's only investment adviser (Franklin Portfolio
Associates was added as an adviser in 1990; Husic Capital Management and
Vanguard Core Management Group were added in 1993).

SHARE PRICE

The Fund's share price, called its net asset value, is calculated each business
day after the close of regular trading (generally 4:00 p.m. Eastern time) of the
New York Stock Exchange. Net asset value per share is computed by adding up the
total value of the Fund's investments and other assets, subtracting any of its
liabilities, or debts, and then dividing by the number of Fund shares
outstanding:

                                Total Assets  -  Liabilities
   Net Asset Value  =           ----------------------------
                                Number of Shares Outstanding

     Daily net asset value, or NAV, 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 Group. Different newspapers use
different abbreviations of the Fund's name, but the most common is Morg.

                                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.

                                PLAIN TALK ABOUT

                                  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 the 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. The capital gains are either short-term or long-term depending on
whether the fund held the securities for less than or more than one year.

                                PLAIN TALK ABOUT

                      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, 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.


DIVIDENDS, CAPITAL GAINS, AND TAXES

Each December, the Fund distributes to shareholders virtually all of its income
from interest and dividends, as well as any capital gains realized from the sale
of securities.

     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 own tax adviser about the tax consequences of an
investment in the Fund and of any plan withdrawals.

     If your Vanguard/Morgan Growth 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 own tax adviser about other tax consequences
of an investment in the Fund.

THE FUND AND VANGUARD

     The Fund is a member of The Vanguard Group, a family of more than 30
investment companies with more than 90 distinct investment portfolios and total
net assets of more than $200 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 percentage of the
Fund's assets subject to the control of the Officers and Directors of the Fund.

     Wellington Management Company (WMC), 75 State Street, Boston, MA 02109, was

billion in stock and bond portfolios, including 13 Vanguard Funds. As of

     Husic Capital Management (Husic), 555 California Street, Suite 2900, San
Francisco, CA 94104, was founded in 1986 and manages about $3.3 billion in
assets. Husic managed 13% of Morgan Growth Fund's assets as of December 31,

assets as of year end 1995. Vanguard Core Management Group provides advisory
services to the Fund on an at-cost basis.

them to get the best available price and most favorable execution from these
brokers with respect to all transactions.

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

GENERAL INFORMATION

Vanguard/Morgan Growth Fund is organized under the laws of the State of
Maryland. Shareholders of the 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. Although the Fund does not usually hold an annual meeting,
shareholders may request one under certain circumstances, which are described in
the Statement of Additional Information.

                       INVESTMENT OBJECTIVE AND POLICIES
 
     PORTFOLIO TURNOVER  While the rate of portfolio turnover is not a limiting
factor when management deems changes appropriate, it is anticipated that the
Fund's annual portfolio turnover rate will not normally exceed 100%. A rate of
turnover of 100% could occur, for example, if all of the securities in the
Fund's portfolio are replaced within a period of one year. The Fund's portfolio
turnover rate for each of its last ten fiscal years is set forth under
"Financial Highlights," in the Fund's Prospectus.
 
     REPURCHASE AGREEMENTS  The Fund may invest in repurchase agreements with
commercial banks, brokers or dealers either for defensive purposes due to market
conditions or to generate income from its excess cash balances. A repurchase
agreement is an agreement under which the Fund acquires a money market
instrument (generally a security issued by the U.S. Government or an agency
thereof, a banker's acceptance or a certificate of deposit) from a commercial
bank, broker or dealer, subject to resale to the seller at an agreed upon price
and date (normally, the next business day). A repurchase agreement may be
considered a loan collateralized by securities. The resale price reflects an
agreed upon interest rate effective for the period the instrument is held by the
Fund and is unrelated to the interest rate on the underlying instrument. In
these transactions, the securities acquired by the Fund (including accrued
interest earned thereon) must have a total value in excess of the value of the
repurchase agreement and are held by a custodian bank until repurchased. In
addition, the Fund's Board of Directors will monitor the Fund's repurchase
agreement transactions generally and will establish guidelines and standards for
review by the investment adviser of the creditworthiness of any bank, broker or
dealer party to a repurchase agreement with the Fund. No more than an aggregate
of 15% of the Fund's assets, at the time of investment, will be invested in
repurchase agreements having maturities longer than seven days and securities
subject to legal or contractual restrictions on resale for which there are no
readily available market quotations. From time to time, the Fund's Board of
Directors may determine that certain restricted securities known as Rule 144A
securities are liquid and not subject to the 15% limitation described above. See
"Illiquid Securities" on page 3.
 
     The use of repurchase agreements involves certain risks. For example, if
the other party to the agreement defaults on its obligation to repurchase the
underlying instrument at a time when the value of the security has
 
                                        1
<PAGE>   47
 
declined, the Fund may incur a loss upon disposition of the security. If the
other party to the agreement becomes insolvent and subject to liquidation or
reorganization under the Bankruptcy Code or other laws, a court may determine
that the underlying security is collateral for a loan by the Fund not within the
control of the Fund and therefore the realization by the Fund on such collateral
may be automatically stayed. Finally, it is possible that the Fund may not be
able to substantiate its interest in the underlying security and may be deemed
an unsecured creditor of the other party to the agreement. While the Fund's
management acknowledges these risks, it is expected that they can be controlled
through careful monitoring procedures.
 
     LENDING OF SECURITIES  The Fund may lend its securities on a short-term or
long-term basis 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, the Fund attempts to increase
its net investment income through the receipt of interest on the loan. Any gain
or loss in the market price of the securities loaned that might occur during the
term of the loan would be for the account of the Fund. The Fund may lend its
portfolio securities to qualified brokers, dealers, banks or other financial
institutions, so long as the terms, the structure and the aggregate amount of
such loans are not inconsistent with the Investment Company Act of 1940, or the
Rules and Regulations or interpretations of the Securities and Exchange
Commission (the "Commission") thereunder, which currently require that (a) the
borrower pledge and maintain with the Fund collateral consisting of cash, an
irrevocable letter of credit issued by a domestic U.S. bank, or securities
issued or guaranteed by the U.S. 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 Fund at any time and (d) the Fund receive reasonable interest
on the loan (which may include the Fund's investing any cash collateral in
interest bearing short-term investments), any distribution on the loaned
securities and any increase in their market value. Loan arrangements made by the
Fund will comply with all other applicable regulatory requirements, including
the rules of the New York Stock Exchange, which rules presently require the
borrower, after notice, to redeliver the securities within the normal settlement
time of three business days. All relevant facts and circumstances, including the
creditworthiness of the broker, dealer or institution, will be considered in
making decisions with respect to the lending of securities, subject to review by
the Fund's Board of 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. In addition, voting rights pass
with the loaned securities, but if a material event will occur affecting an
investment on loan, the loan must be called and the securities voted.
 
     FOREIGN INVESTMENTS  As indicated in the Prospectus, the 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.
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 those countries.
 
     Although the Fund will endeavor to achieve 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 Fund's foreign securities will be somewhat greater than the
expenses for the custodial arrangement for handling U.S. securities of equal
value.
 
                                        2

     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 the Fund receives from its foreign investments.
 
     Currency Risk  Since the stocks of foreign companies are frequently
denominated in foreign currencies, and since the 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 the 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  The Fund may enter into futures contracts, options, and
options on futures contracts 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," or "selling" a contract previously
purchased) in an identical contract to terminate the position. Brokerage
commissions are incurred when a futures contract is bought or sold.
 
     Futures traders are required to make a good faith margin deposit in cash or
government securities with a broker or custodian to initiate and maintain open
positions in futures contracts. A margin deposit is intended to assure
completion of the contract (delivery or acceptance of the underlying security)
if it is not terminated prior to the specified delivery date. Minimal initial
margin requirements are established by the futures exchange and may be changed.
Brokers may establish deposit requirements which are higher than the exchange
minimums. Futures contracts are customarily purchased and sold on margin which
may range upward from less than 5% of the value of the contract being traded.
 
     After a futures contract position is opened, the value of the contract is
marked to market daily. If the futures contract price changes to the extent that
the margin on deposit does not satisfy margin requirements, payment of
additional "variation" margin will be required. Conversely, change in the
contract value may reduce the required margin, resulting in a repayment of
excess margin to the contract holder. Variation margin payments are made to and
from the futures broker for as long as the contract remains open. The Fund
expects to earn interest income on its margin deposits.
 
     Traders in futures contracts may be broadly classified as either "hedgers"
or "speculators." Hedgers use the futures markets primarily to offset
unfavorable changes in the value of securities otherwise held for investment
purposes or expected to be acquired by them. Speculators are less inclined to
own the securities underlying the futures contracts which they trade, and use
futures contracts with the expectation of realizing
 
                                        3
<PAGE>   49
 
profits from fluctuations in the prices of underlying securities. The Fund
intends to use futures contracts only for bona fide hedging purposes.
 
     Regulations of the CFTC applicable to the Fund require that all of its
futures transactions constitute bona fide hedging transactions. The Fund will
only sell futures contracts to protect securities it owns against price declines
or purchase contracts to protect against an increase in the price of securities
it intends to purchase. As evidence of this hedging interest, the Fund expects
that approximately 75% of its futures contract purchases will be "completed,"
that is, equivalent amounts of related securities will have been purchased or
are being purchased by the Fund upon sale of open futures contracts.
 
     Although techniques other than the sale and purchase of futures contracts
could be used to control the Fund's exposure to market fluctuations, the use of
futures contracts may be a more effective means of hedging this exposure. While
the Fund will incur commission expenses in both opening and closing out futures
positions, these costs are lower than transaction costs incurred in the purchase
and sale of the underlying securities.
 
     RESTRICTIONS ON THE USE OF FUTURES CONTRACTS  The Fund will not enter into
futures contract transactions to the extent that, immediately thereafter, the
sum of its initial margin deposits on open contracts exceeds 5% of the market
value of the Fund's total assets. In addition, the Fund will not enter into
futures contracts to the extent that its outstanding obligations to purchase
securities under these contracts would exceed 20% of the Fund's total assets.
 
     RISK FACTORS IN FUTURES TRANSACTIONS  Positions in futures contracts may be
closed out only on an Exchange which provides a secondary market for such
futures. However, there can be no assurance that a liquid secondary market will
exist for any particular futures contract at any specific time. Thus, it may not
be possible to close a futures position. In the event of adverse price
movements, the Fund would continue to be required to make daily cash payments to
maintain its required margin. In such situations, if the Fund has insufficient
cash, it may have to sell portfolio securities to meet daily margin requirements
at a time when it may be disadvantageous to do so. In addition, the Fund may be
required to make delivery of the instruments underlying futures contracts it
holds. The inability to close options and futures positions also could have an
adverse impact on the ability to effectively hedge it.
 
     The Fund will minimize the risk that it will be unable to close out a
futures contract by only entering into futures which are traded on national
futures exchanges and for which there appears to be a liquid secondary market.
The principal stock index futures exchanges in the United States are the Board
of Trade of the City of Chicago and the Chicago Mercantile Exchange.
 
     The risk of loss in trading futures contracts in some strategies can be
substantial, due to the low margin deposits required. As a result, a relatively
small price movement in a futures contract may result in immediate and
substantial loss (as well as gain) to the investor. For example, if at the time
of purchase, 10% of the value of the futures contract is deposited as margin, a
subsequent 10% decrease in the value of the futures contract would result in a
total loss of the margin deposit, before any deduction for the transaction
costs, if the account were then closed out. A 15% decrease would result in a
loss equal to 150% of the original margin deposit if the contract were closed
out. Thus, a purchase or sale of a futures contract may result in losses in
excess of the amount invested in the contract. The Fund is not subject to
extreme losses from futures because 100% of the contract obligation is held
separately in cash or cash equivalents. The Fund would presumably have sustained
comparable losses if, instead of the futures contract, it had invested in the
underlying financial instrument and sold it after the decline.
 
     Utilization of futures transactions by the Fund does involve the risk of
imperfect or no correlation where the securities underlying futures contracts
have different maturities than the portfolio securities being hedged. It is also
possible that the Fund could both lose money on futures contracts and also
experience a decline in value of its portfolio securities. There is also the
risk of loss by the Fund of margin deposits in the event of bankruptcy of a
broker with whom the Fund has an open position in a futures contract or related
option. Additionally, investments in futures contracts and options involve the
risk that the investment advisers will incorrectly predict stock market and
interest rate trends.
 
                                        4

     Most futures exchanges limit the amount of fluctuation permitted in futures
contract prices during a single trading day. The daily limit establishes the
maximum amount that the price of a futures contract may vary either up or down
from the previous day's settlement price at the end of a trading session. Once
the daily limit has been reached in a particular type of contract, no trades may
be made on that day at a price beyond that limit. The daily limit governs only
price movement during a particular trading day and therefore does not limit
potential losses, because the limit may prevent the liquidation of unfavorable
positions. Futures contract prices have occasionally moved to the daily limit
for several consecutive trading days with little or no trading, thereby
preventing prompt liquidation of future positions and subjecting some futures
traders to substantial losses.
 
     FEDERAL TAX TREATMENT OF FUTURES CONTRACTS  The Fund is required for
federal income tax purposes to recognize as income for each taxable year its net
unrealized gains and losses on certain futures contracts as of the end of the
year as well as those actually realized during the year. In most cases, any gain
or loss recognized with respect to a futures contract is considered to be 60%
long-term capital gain or loss and 40% short-term capital gain or loss, without
regard to the holding period of the contract. Furthermore, sales of futures
contracts which are intended to hedge against a change in the value of
securities held by the Fund may affect the holding period of such securities
and, consequently, the nature of the gain or loss on such securities upon
disposition. A Fund may be required to defer the recognition of losses on
futures contracts to the extent of any unrecognized gains on related positions
held by the Fund.
 
     In order for the Fund to continue to qualify for federal income tax
treatment as a regulated investment company, at least 90% of its gross income
for a taxable year must be derived from qualifying income; i.e., dividends,
interest, income derived from loans of securities, gains from the sale of
securities or of foreign currencies or other income derived with respect to the
Fund's business of investing in securities. In addition, gains realized on the
sale or other disposition of securities held for less than three months must be
limited to less than 30% of the Fund's annual gross income. It is anticipated
that any net gain realized from the closing out of futures contracts will be
considered gain from the sale of securities and therefore be qualifying income
for purposes of the 90% requirement. In order to avoid realizing excessive gains
on securities held less than three months, the Fund may be required to defer the
closing out of futures contracts beyond the time when it would otherwise be
advantageous to do so. It is anticipated that unrealized gains on futures
contracts, which have been open for less than three months as of the end of the
Fund's fiscal year and which are recognized for tax purposes, will not be
considered gains on sales of securities held less than three months for the
purpose of the 30% test.
 
     The Fund will distribute to shareholders annually any net capital gains
which have been recognized for federal income tax purposes (including unrealized
gains at the end of the Fund's fiscal year) on futures transactions. Such
distributions will be combined with distributions of capital gains realized on
the Fund's other investments and shareholders will be advised on the nature of
the distributions.
 
                             INVESTMENT LIMITATIONS
 
     The following restrictions and fundamental policies cannot be changed
without approval of the holders of a majority of the outstanding shares of the
Fund (as defined in the Investment Company Act of 1940). The Fund may not under
any circumstances:
 
      1) Borrow money, except from banks (or through reverse repurchase
         agreements), for temporary or emergency (not leveraging) purposes, and
         then in an amount not exceeding 10% of the value of the Fund's net
         assets (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 Fund's net assets,
         the Fund will not make any additional investments;
 
      2) 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 Fund would
         hold more than 10% of the outstanding voting securities of the issuer,
         or more than 5% of the value of the Fund's total assets would be
         invested in the securities of such issuer;
 
                                        5
<PAGE>   51
 
      3) Invest for the purpose of exercising control of management of any
         company;
 
      4) 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 Fund's shareholders or otherwise to the extent
         permitted by Section 12 of the Investment Company Act of 1940. The Fund
         will invest only in investment companies which have investment
         objectives and investment policies consistent with those of the Fund;
 
      5) Engage in the business of underwriting securities issued by others,
         except to the extent that the Fund may technically be deemed to be an
         underwriter under the Securities Act of 1933, as amended, in disposing
         of portfolio securities;
 
      6) 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 the Fund's investment in The Vanguard Group, Inc., as
         described on page 8);
 
      7) Invest in commodities (except that the Fund may invest in stock futures
         contracts and options to the extent that not more than 5% of the Fund's
         assets are required as deposit to secure obligations under futures
         contracts and not more than 20% of the Fund's assets are invested in
         futures and options at any time) or real estate although the Fund may
         purchase and sell securities of companies which deal in real estate, or
         interests therein;
 
      8) Purchase securities on margin or sell any securities short (except as
         specified in 7) above;
 
      9) Invest more than 5% of the assets of the Fund, at the time of
         investment, in the securities of any issuers which have (with
         predecessors) a record of less than three years' continuous operation;
 
     10) Lend money to any person 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) by lending its portfolio securities as provided
         under "Lending of Securities";
 
     11) Pledge, mortgage, or hypothecate any of its assets to an extent greater
         than 5% of its total assets; and
 
     12) Invest more than 25% of the value of its total assets in any one
         industry.
 
     These investment limitations are considered at the time investment
securities are purchased.
 
     Although not fundamental policies subject to shareholder vote, as long as
the Fund's shares are registered for sale in certain states, it will not (i)
invest in put, call, straddle or spread options, and (ii) invest in interests in
oil, gas or other mineral exploration or development programs.
 
     Each Portfolio may not purchase or retain securities of an issuer if an
officer or director of such issuer is an officer or Director of the Fund or its
investment adviser and one or more of such officers or Directors of the Fund or
its investment adviser owns beneficially more than  1/2% of the shares or
securities of such issuer and all such directors and officers owning more than
 1/2% of such shares or securities together own more than 5% of such shares or
securities.
 
     Notwithstanding these limitations, the Fund may own all or any portion of
the securities of, or make loans to, or contribute to the costs or other
financial requirements of any company which will be wholly owned by the Fund and
one or more other investment companies and is primarily engaged in the business
of providing, at-cost, management, administrative, distribution or related
services to the Fund and other investment companies. See "Management of the
Fund."
 
                               PURCHASE OF SHARES
 
     The Fund reserves the right in its sole discretion (i) to suspend the
offerings of its shares, (ii) to reject purchase orders when in the judgment of
management such rejection is in the best interest of the Fund, and (iii) to
reduce or waive the minimum investment for or any other restrictions on initial
and subsequent
 
                                        6
<PAGE>   52
 
investments for certain fiduciary accounts or under circumstances where certain
economies can be achieved in sales of the Fund's shares.
 
                              REDEMPTION OF SHARES
 
     The Fund may suspend redemption privileges or postpone the date of payment
(i) during any period that the New York Stock Exchange is closed, or trading on
the Exchange is restricted as determined by the Securities and Exchange
Commission (the "Commission"), (ii) during any period when an emergency exists
as defined by the rules of the Commission as a result of which it is not
reasonably practicable for the Fund to dispose of securities owned by it, or
fairly to determine the value of its assets, and (iii) for such other periods as
the Commission may permit.
 
     The Fund has made an election with the Commission to pay in cash all
redemptions requested by any shareholder of record limited in amount during any
90-day period to the lesser of $250,000 or 1% of the net assets of the Fund 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 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 Fund. If redemptions are
paid in investment securities, such securities will be valued as set forth in
the Prospectus under "The Fund's Share Price" and a redeeming shareholder would
normally incur brokerage expenses if he converted these securities to cash.
 
     No charge is made by the Fund for redemptions. Any redemption may be more
or less than the shareholder's cost depending on the market value of the
securities held by the Fund.

                             MANAGEMENT OF THE FUND
 
OFFICERS AND DIRECTORS
 
     The Fund's officers, under the supervision of the Board of Directors,

                               THE VANGUARD GROUP
 
     Vanguard/Morgan Growth Fund, Inc. is a member of The Vanguard Group of
Investment Companies.
 
     Through their jointly-owned subsidiary, The Vanguard Group, Inc.
("Vanguard"), the Fund and the other Funds in the Group obtain at cost virtually
all of their corporate management, administrative and distribution services.
Vanguard also provides investment advisory services on an at-cost basis to
certain 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 net 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 Fund's officers are also officers and employees of Vanguard. No officer
or employee owns, or is permitted to own, any securities of any external adviser
for the Funds.
 
     The Vanguard Group adheres to a Code of Ethics established pursuant to Rule
17j-1 under the Investment Company Act of 1940. The Code is designed to prevent
unlawful practices in connection with the purchase or sale of securities by
persons associated with Vanguard. Under Vanguard's Code of Ethics certain
officers and employees of Vanguard who are considered access persons are
permitted to engage in personal securities transactions. However, such
transactions are subject to procedures and guidelines substantially similar to
those recommended by the mutual fund industry and approved by the U.S.
Securities and Exchange Commission.
 
     The Vanguard Group was established and operates under a Funds' Service
Agreement which was approved by the shareholders of each of the Funds. The
amounts which each of the Funds has invested are adjusted from time to time in
order to maintain the proportionate relationship between each Fund's relative
net assets and its contribution to Vanguard's capital. At December 31, 1995, the
Fund had contributed capital of $172,000 to Vanguard, representing .9% of
Vanguard's capitalization. The Fund's Service Agreement provides as follows: (a)
each Vanguard Fund may invest up to .40% of its current 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 December 31, 1995, the Fund's share of Vanguard's actual net
costs of operation relating to management and administrative services (including
transfer agency) totaled approximately $3,929,000.
 
     DISTRIBUTION  Vanguard provides all distribution and marketing activities
for the Funds in the Group. Vanguard Marketing Corporation, a wholly-owned
subsidiary of The Vanguard Group, Inc., acts as Sales Agent for the shares of
the Funds in connection with any sales made directly to investors in the states
of Florida, Missouri, New York, Ohio, Texas and such other states as it may be
required.
 
     The principal distribution expenses are for advertising, promotional
materials and marketing personnel. Distribution services may also include
organizing and offering to the public, from time to time, one or more new
investment companies which will become members of the Group. The 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 relative net assets. The remaining one
half of those expenses is allocated among the Funds based upon each Fund's sales
for the preceding 24 months relative to the total sales of the Funds as a Group,
provided, however, that no Fund's aggregate quarterly rate of contribution for
distribution expenses of a marketing and promotional nature shall exceed 125% of
average distribution expense rate for the Group, and that no Fund shall incur
annual distribution expenses in excess of 20/100 of 1% of its average month-end
net assets. During the fiscal year ended December 31, 1995, the Fund paid
approximately $203,000 of the Group's distribution and marketing expenses.

     INVESTMENT ADVISORY SERVICES  Vanguard also provides the Fund, Vanguard
Money Market Reserves, Vanguard Municipal Bond Fund, several Portfolios of
Vanguard Fixed Income Securities Fund, Vanguard California Tax-Free Fund,
Vanguard Florida Insured Tax-Free Fund, Vanguard New Jersey Tax-Free Fund,
Vanguard New York Insured Tax-Free Fund, Vanguard Ohio Tax-Free Fund, Vanguard
Pennsylvania Tax-Free Fund, Vanguard Admiral Funds, Vanguard Institutional Index
Fund, Vanguard Bond Index Fund, Vanguard Balanced Index Fund, Vanguard Index
Trust, Vanguard International Equity Index Fund, Vanguard Tax-Managed Fund, the
Aggressive Growth Portfolio of Vanguard Horizon Fund, several Portfolios of
Vanguard Variable Insurance Fund, a portion of Vanguard/Windsor II as well as
several indexed separate accounts with investment advisory services. These
services are provided on an at-cost basis from a money management staff employed
directly by Vanguard. The compensation and other expenses of this staff are paid
by the Funds utilizing these services.
 
     REMUNERATION OF DIRECTORS AND OFFICERS  The Fund pays each Director, who is
not also an officer, an annual fee plus travel and other expenses incurred in
attending Board meetings. The Fund's officers and employees are paid by Vanguard
which, in turn, is reimbursed by the Fund and each other Fund in the Group, for
its proportionate share of officers' and employees' salaries and retirement
benefits.
 
     During the fiscal year ended December 31, 1995, the Fund paid approximately
$5,000 in Directors' fees and expenses to its "non-interested" Directors. The
Fund's proportionate share of remuneration paid by Vanguard (and reimbursed by
the Fund) during the fiscal year to all officers of the Fund, as a group, was
approximately $48,299.
 
     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 an eligible
officer's compensation during the year, if any, that exceeds the Social Security
Taxable Wage Base then in effect. Under its thrift plan, all employees are
permitted to make pre-tax basic contributions in an amount up to 4% of total
compensation which Vanguard matches on a 100% basis. 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, upon retirement. 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 to 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. The Fund's
proportionate share of retirement benefits paid by Vanguard on behalf of all
eligible officers of the Fund, as a group, during the fiscal year ended December
31, 1995 was approximately $1,350.
 
     The following table provides detailed information with respect to the
amounts paid or accrued for the Directors for the fiscal year ended December 31,
1995.

                           INVESTMENT ADVISORY SERVICES
 
     The Fund currently employs four separate investment advisers each of whom
manages the investment and reinvestment of a portion of the Fund's assets. Prior
to April 24, 1990 Wellington Management Company served as the Fund's sole
investment adviser.
 
     WELLINGTON MANAGEMENT COMPANY  The Fund employs Wellington Management
Company ("WMC") under an investment advisory agreement dated as of April 1,
1996, to manage the investment and reinvestment of approximately 40% of the
assets of the Fund and to continuously review, supervise and administer the
Fund's investment program. WMC discharges its responsibilities subject to the
control of the officers and Directors of the Fund.
 
     The 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
the Fund's average month-end net assets for the quarter:
 
<TABLE>

                    Over $1 billion....................................  0.075%
</TABLE>
 
     The Basic Fee may be increased or decreased by applying an
incentive/penalty fee based on the investment performance of the assets of the
Fund managed by WMC relative to the investment record of The Growth Fund Stock
Index (the "Index") which is described in detail in the Prospectus.
 
     The following table sets forth the incentive/penalty fee rates payable by
the Fund to WMC under the investment advisory agreement:

</TABLE>
 
- ------------
*For purposes of this calculation, the basic fee is calculated by applying the
 quarterly rate against average assets over the 36-month period.
 
     Under the rules of the Securities and Exchange Commission, the new
incentive/penalty fee will not be fully operable until the quarter ending March
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 the Fund's previous investment advisory agreement with the
Adviser(1) (the "previous rate") shall be used as follows:
 
     1. QUARTER ENDING JUNE 30, 1996.  The incentive/penalty fee shall be
calculated as the sum of 8.3% (e.g., one of 12 quarters) of the fee payable
under the new rate plus 91.7% (e.g., 11 of 12 quarters) 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 .0375% per annum (.009375 of 
1% 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 Growth Fund Stock Index and .075% per annum (0.1875 of 1% per) 
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 Growth Fund Stock Index.

<PAGE>   57
 
     2. QUARTER ENDING SEPTEMBER 30, 1996.  The incentive/penalty fee shall be
calculated as the sum of 16% of the fee payable under the new rate plus 83.4% of
the fee payable under the previous rate.
 
     3. QUARTER ENDING DECEMBER 31, 1996.  The incentive/penalty fee shall be
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 MARCH 31, 1997.  The incentive/penalty fee shall be
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 JUNE 30, 1997.  The incentive/penalty fee shall be
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 SEPTEMBER 30, 1997.  The incentive/penalty fee shall be
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 DECEMBER 31, 1997.  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 MARCH 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 JUNE 30, 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.
 
   10. QUARTER ENDING SEPTEMBER 30, 1998.  The incentive/penalty fee shall be
calculated as the sum of 83.4% of the fee payable under the new rate plus 16.6%
of the fee payable under the previous rate.
 
   11. QUARTER ENDING DECEMBER 31, 1998.  The incentive/penalty fee shall be
calculated as the sum of the fee payable under the new rate plus 8.3% of the fee
payable under the previous rate.
 
   12. QUARTER ENDING MARCH 31, 1999.  New rate fully operable.
 
     For the purpose of determining the fee adjustment for investment
performance, as described above, the net assets of the WMC Portfolio shall be
averaged over the same period as the investment performance of the WMC Portfolio
and the investment record of the Growth Fund Stock Index are computed. The
investment performance of the WMC Portfolio for such period, expressed as a
percentage of the WMC Portfolio's net asset value per share at the beginning of
such period, shall be the sum of: (i) the change in the WMC Portfolio's net
asset value per share during such period; (ii) the value of the WMC Portfolio's
cash distributions per share having an ex-dividend date occurring within such
period; and (iii) the per share amount of capital gains taxes paid or accrued
during such period by the WMC Portfolio for undistributed realized long-term
capital gains.
 
     The investment record of the Growth Fund Stock Index for any period,
expressed as a percentage of the Growth Fund Stock Index level at the beginning
of such period, shall be the sum of (i) the change in the level of the Growth
Fund Stock Index during such period and (ii) the value, computed consistently
with the Growth Fund Stock Index, of cash distributions having an ex-dividend
date occurring within such period made by companies whose securities comprise
the Growth Fund Stock Index. The foregoing notwithstanding, any computation of
the investment performance of the WMC Portfolio and the investment record of the
Growth Fund Stock Index shall be in accordance with any then applicable rules of
the Securities and Exchange Commission.
 
     In April 1972, the Securities and Exchange Commission ("SEC") issued
Release No. 7113 under the Investment Company Act of 1940 to call 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 plus or minus 10 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
 
                                       12
<PAGE>   58
 
maximum fee adjustment may be made." The Release concludes that the directors of
a fund "should satisfy themselves that the maximum performance adjustment will
be made only for performance differences that can reasonably be considered
significant." The Board of Directors of the Fund has fully considered the SEC
Release and believes that the performance adjustments as included in the
agreement are entirely appropriate although not within the plus or minus 10 
percentage points per year range suggested in the Release. Under the Fund's 
investment advisory agreement, the maximum performance adjustment is made 
at a difference of plus or minus 12 percentage points from the performance 
of the index over a thirty-six month period, which would effectively be 
the equivalent of approximately plus or minus 4 percentage points difference 
per year. The Fund's investment advisory agreement provides for no performance
adjustment at a difference of less than plus or minus 6 percentage points
from the performance of the index over a thirty-six month period, which would be
the equivalent of approximately 2 percentage points per year.
 
     DURATION AND TERMINATION.  The new agreement with WMC became effective
April 1, 1996. This agreement shall continue in effect until March 31, 1998, and
thereafter, only so long as such continuance is approved at least annually by a
vote of the Fund's Board of Directors, including the affirmative votes of a
majority of the Directors who are not parties to the contract or "interested
persons" (as defined in the Investment Company Act of 1940) of any such party,
cast in person at a meeting called for the purpose of considering such approval.
In addition, the question of continuance of the agreement may be presented to
the shareholders of the Fund; in such event, continuance shall be effected only
if approved by the affirmative vote of a majority of the outstanding voting
securities of the Fund. The agreement may be terminated without penalty at any
time (1) either by vote of the Board of Directors of the Fund or by vote of a
majority of the outstanding voting securities of the Fund on sixty (60) days'
written notice to WMC, or (2) by WMC upon ninety (90) days' written notice to
the Fund.
 
     PORTFOLIO TRANSACTIONS  The investment advisory agreement authorizes WMC
(with the approval of the Fund's Board of Directors) to select the brokers or
dealers that will execute the purchases and sales of portfolio securities for
the Fund and directs WMC to use its best efforts to obtain the best available
price and most favorable execution as to all transactions for the Fund. WMC 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, WMC 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 Fund and/or WMC, and WMC
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 agreement also incorporates the concepts of Section
28(e) of the Securities Exchange Act of 1934 by providing that, subject to the
approval of the Fund's Board of Directors, WMC may cause the Fund 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 transactions; provided that such commission is deemed
reasonable in terms of either that particular transaction or the overall
responsibilities of WMC to the Fund and the other Funds in the Group.
 
     Currently, it is the Fund's policy that WMC 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. WMC will only pay such higher commissions if
it believes this to be in the best interest of the Fund. 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 WMC and/or the Fund. However, WMC has informed the Fund that it
will not pay higher commission rates specifically for the purpose of obtaining
research services.

     Since the Fund does not market its shares through intermediary brokers or
dealers, it is not the Fund's practice to allocate brokerage or principal
business on the basis of sales of its shares which may be effected through such
firms. However, the Fund may place portfolio orders with qualified
broker-dealers who recommend the Fund to other clients, or who act as agent in
the purchase of the Fund'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 Fund shares by a broker or dealer
in selecting among qualified broker-dealers.

     FRANKLIN PORTFOLIO ASSOCIATES TRUST  The Fund employs Franklin Portfolio
Associates Trust ("Franklin") under an investment advisory agreement dated as of
April 1, 1996 to manage the investment and reinvestment of approximately
one-third of the Fund's assets. Franklin discharges its responsibilities subject
to the control of the Officers and Directors of the Fund.
 
     The Fund pays Franklin Basic Fee by applying various percentage rates to
the average net assets of the Fund managed by Franklin. The fee schedule is as
follows:

                    Over $500 million...................................  0.10%
</TABLE>
 
     The Basic Fee may be increased or decreased by applying an
incentive/penalty fee based on the investment performance of the Fund relative
to the investment record of the Index. Such incentive/penalty fee provides for
an increase or decrease in Franklin's basic fee in an amount equal to .10% per
annum (.025% per quarter) of the average month-end net assets of the portion of
the Fund managed by Franklin if the investment performance of that portion of
the Fund for the thirty-six months preceding the end of the quarter is six
percentage points or more above or below, respectively, the investment record of
the Index for the same period.
 
     The following table sets forth the incentive/penalty fee rates payable by
the Fund to Franklin under the investment advisory agreement:

     The investment performance of the FPA Portfolio, the "FPA Portfolio unit

manner as set forth under the discussion of the WMC Agreement on page 10.
 
                                       14
<PAGE>   60
 
     For the purposes of determining the incentive/penalty fee, the net assets
of the FPA Portfolio will be averaged over the same period as the investment
performance of the FPA Portfolio and the investment record of the Index are
computed.
 
     The formula used to determine the performance adjustments, differs from the
view taken by the staff of the Securities and Exchange Commission. For a more
detailed discussion, see page 11. The Board of Directors of the Fund believes
that the performance adjustments, as included in the proposed agreement with
FPA, are appropriate although less than the plus or minus 10 percentage 
points per year range suggested in SEC Release No. 7113. Under the proposed 
agreement, the maximum performance adjustment is made at a difference of 
approximately plus or minus 2 percentage points per year.
 
     The agreement with FPA is dated April 1, 1996 and continues until March 31,
1998, and thereafter, only so long as such continuance is approved by a vote of
the Fund's Board of Directors, including the affirmative votes of a majority of
the Directors who are not parties to the contract or "interested persons" (as
defined in the Investment Company Act of 1940) of any such party, cast in person
at a meeting called for the purpose of considering such approval. In addition,
the question of continuance of the agreement may be presented to the
shareholders of the Fund; in such event, such continuance shall be effected only
if approved by the affirmative vote of a majority of the outstanding voting
securities of the Fund. The agreement may be terminated without penalty at any
time (1) either by vote of the Board of Directors of the Fund or by vote of a
majority of the outstanding voting securities of the Fund on 60 days' written
notice to FPA, or (2) by FPA upon 90 days' written notice to the Fund.
 
     During the last three fiscal years, the Fund paid FPA the following
advisory fees:

     The basic fee paid to Husic, as provided above, may be increased or
decreased by applying an incentive/penalty fee based on the investment
performance of the Husic Portfolio relative to the investment record of the
Growth Fund Stock Index ("Growth Index"). Under the incentive/penalty fee
schedule, the basic fee payable to Husic may be increased or decreased by as
much as 75% of the basic fee depending on the investment performance of the

investment companies, other institutions, and individuals. Frank J. Husic,
managing partner, is a controlling person of Husic. Husic's general partner is
Frank J. Husic & Co., a California corporation that is wholly owned by Frank J.
Husic. As of December 31, 1995, Husic provided investment advisory services to
clients having assets with an approximate value of $3.2 billion.
 
     With respect to each adviser, the Fund'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.
 
     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 only 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.
 
                             PORTFOLIO TRANSACTIONS
 
     The investment advisory agreements authorize the Advisers (with the
approval of the Fund's Board of Directors) to select the brokers or dealers that
will execute the purchases and sales of portfolio securities for the Fund and
directs the Advisers to use their best efforts to obtain the best available
price and most favorable execution as to all transactions for the Fund. The
Advisers have undertaken to execute each investment transaction at a price and
commission which provides the most favorable total cost or proceeds reasonably
 
                                       17
<PAGE>   63
 
obtainable under the circumstances. During the fiscal years ended December 31,
1993, 1994 and 1995 the Fund paid $1,577,672, $1,931,684 and $1,492,129
respectively, in brokerage commissions.
 
     In placing portfolio transactions, the Advisers will use their 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 Fund and/or the
Advisers. The Advisers consider such information useful in the performance of
their obligations under the agreement but are 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 Fund's Board of Directors, the Advisers may cause the Fund 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 Advisers to the Fund and the other Funds in the Group.
 
     Currently, it is the Fund's policy that the Advisers 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. The Advisers will only pay such higher
commissions if they believe this to be in the best interest of the Fund. 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 the Advisers and/or the Fund. However, the
Advisers have informed the Fund that they will not pay higher commission rates
specifically for the purpose of obtaining research services.
 
     Since the Fund does not market its shares through intermediary brokers or
dealers, it is not the Fund's practice to allocate brokerage or principal
business on the basis of sales of its shares which may be through such firms.
However, the Fund may place portfolio orders with qualified broker-dealers who
recommend the Fund to other clients, or who act as agent in the purchase of the
Fund'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 Fund shares by a broker or dealer in selecting among
qualified broker-dealers.
 
     Some securities considered for investment by the Fund may also be
appropriate for other Funds and/or clients served by the Advisers. If purchase
or sale of securities consistent with the investment policies of the Fund and
one or more of these other Funds or clients serviced by the Advisers 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 Advisers.
 
                             YIELD AND TOTAL RETURN
 
     The yield of the Fund for the 30-day period ended December 31, 1995 was
+1.10%.
 
     The average annual total return of the Fund for the one-, five- and
ten-year periods ending December 31, 1995 was +35.98%, +15.25% and +13.03%,
respectively. Total return is computed by finding 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.
 
                              PERFORMANCE MEASURES
 
     There are a number of different ways to measure the performance of a mutual
fund. One of the these methods is to calculate the current yield of a fund or
portfolio. This is done by dividing the total amount of dividends per share paid
by a fund during the past twelve months by a current offering price (including
the sales charge, if any). Under certain circumstances, such as when there has
been a fundamental change in
 
                                       18
<PAGE>   64
 
investment or dividend policies, it might be appropriate to annualize the
dividends paid over the period such policies were in effect, rather than using
the dividends paid during the past twelve months. An alternate method is to
calculate a compound yield. This is derived by computing the total compounded
dividends paid by a fund during the past twelve months on the assumption that
all dividends were reinvested in additional shares (and giving no effect to
capital gains distributions or taxes) and dividing this by a current offering
price. Another method is to calculate the total return by dividing the change in
value of an investment in shares over a period of time (generally ten years or
more), assuming the reinvestment of all dividends and capital gains
distributions, by the original net asset value of the shares. Regardless of the
method used, past performance is not necessarily indicative of future results,
but are an indication of the return to shareholders only for the limited
historical period used.
 
     From time to time, advertisements, reports and promotional literature
regarding the Fund may compare its yield or total return (as calculated above)
to yields or returns reported by other investments and to various indices and
averages to assist an investor's calculation of how an investment in the Fund
might satisfy his investment objectives.

1995 Annual Report to Shareholders, and the report thereon of Price Waterhouse

                     APPENDIX -- DESCRIPTION OF SECURITIES
 
I.  DESCRIPTION OF FOREIGN INVESTMENTS
 
     The Fund may invest in the securities (payable in U.S. dollars) of foreign
issues and in the securities of foreign branches of U.S. banks such as
negotiable certificates of deposit (Eurodollars). Because the Fund invests in
such securities, investment in the Fund involves investment risks that are
different in some respects from an investment in a fund which invests only in
debt obligations of U.S. issuers. Such risks may include future political and
economic developments, the possible imposition of withholding taxes on interest
income payable on the securities held, possible seizure or nationalization of
foreign deposits, the possible establishment of exchange controls or the
adoption of other restrictions by foreign governments which may adversely affect
the payment of principal and interest on securities held by the Fund, difficulty
in obtaining and enforcing court judgments abroad, the possibility of
restrictions on investments in other jurisdictions, reduced levels of government
regulation of securities markets in foreign countries, and difficulties in
effecting the repatriation of capital invested abroad. A Fund will not purchase
any such foreign security if, as a result, more than 20% of the value of the
Fund's total assets would be invested in such securities.

ITEM 27. INDEMNIFICATION

has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a trustee, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
