Fellow Shareholder:
 
    The accompanying Combined Proxy Statement and Prospectus presents an
important proposal for your consideration as a shareholder of Vanguard
Specialized Portfolios-Service Economy Portfolio (the "Service Economy
Portfolio"). In substance, your Board of Directors has proposed that the Service
Economy Portfolio be merged with Vanguard/Morgan Growth Fund, Inc. ("Morgan
Growth Fund"), by having all of its assets acquired, in a tax-free
reorganization, in exchange for shares of Morgan Growth Fund on June 2, 1994
(the "Closing Date"). If this proposal is approved by shareholders, your Service
Economy Portfolio shares will be exchanged for an equal dollar-amount of Morgan
Growth Fund shares on the Closing Date.
 
BACKGROUND
 
    The Service Economy Portfolio began operations in 1984 with the objective of
providing investors with long-term capital appreciation by investing in common
stocks of companies in the service sector of the economy. Over the period since
its inception the performance of the Service Economy Portfolio has lagged the
performance of competitive funds with similar objectives and that of the overall
stock market. Additionally, the level of investor interest in the Portfolio has
been modest. Accordingly, the Directors of the Service Economy Portfolio have
determined that it would be in the best interest of the Portfolio's shareholders
to merge the Portfolio into the larger and more broadly diversified Morgan
Growth Fund.
 
    Morgan Growth Fund is considered to be the most appropriate Vanguard Fund to
acquire the shares of the Service Economy Portfolio because, of all the Vanguard
equity funds, Morgan Growth Fund has the most similar sector weightings and most
similar market capitalization (company size) to the Service Economy Portfolio's.
Wellington Management Company serves as investment adviser to the Service
Economy Portfolio and also serves as investment adviser with respect to
approximately 40% of Morgan Growth Fund's assets. The remainder of Morgan Growth
Fund's assets are managed by Franklin Portfolio Associates (33%), Husic Capital
Management (13%) and Vanguard's Core Management Group (9%). Approximately 5% of
the Fund's net assets are held in cash.
 
    SHAREHOLDERS OF THE SERVICE ECONOMY PORTFOLIO WILL NOT BE ASSESSED THE
PORTFOLIO'S 1% REDEMPTION FEE ON THE EXCHANGE OF PORTFOLIO SHARES FOR MORGAN
GROWTH FUND SHARES. ADDITIONALLY, SHARES OF THE SERVICE ECONOMY PORTFOLIO
REDEEMED OR EXCHANGED TO ANY OTHER VANGUARD FUND ON OR AFTER APRIL 18, 1994 WILL
NOT BE ASSESSED THE PORTFOLIO'S 1% REDEMPTION FEE. THE SERVICE ECONOMY PORTFOLIO
WILL DISTRIBUTE ALL CURRENT INCOME DIVIDENDS AND REALIZED CAPITAL GAINS TO
SHAREHOLDERS PRIOR TO THE MERGER.
 
    The Officers and Directors of the Service Economy Portfolio have carefully
evaluated the Service Economy Portfolio's performance record since inception,
giving careful consideration to the risks and opportunities of making changes.
The Officers and Directors have concluded that shareholders would be best served
by "merging" the Portfolio through the acquisition of its assets by Morgan
Growth Fund. The proposed reorganization of the Service Economy Portfolio must
be approved by the owners of a majority of the outstanding shares of the Service
Economy Portfolio.
 
    We hope this Proxy statement and the Morgan Growth Fund prospectus will
answer all of your questions, but if you have further questions at any time,
please do not hesitate to call Vanguard's Investor Information Department at
1-800-662-7447.
 
                                        Sincerely,
 
                                        John C. Bogle

             APPROVAL OR DISAPPROVAL OF THE PROPOSED REORGANIZATION
 
                                    SUMMARY
 
     The following is a summary of the proposed reorganization and the parties
thereto contained elsewhere in this Combined Proxy Statement and Prospectus
(including documents incorporated by reference herein).
 
COMPARISON OF THE SERVICE ECONOMY PORTFOLIO AND MORGAN GROWTH FUND
 
  1. Investment Objectives and Policies
 
     The investment objective of the Service Economy Portfolio is to provide
long-term capital appreciation by investing in the stocks of companies in the
service economy industry. Morgan Growth Fund seeks to provide long-term capital
appreciation by investing primarily in the equity securities of growth
companies. Morgan Growth Fund invests a majority of its assets in "established
growth companies"--i.e. larger capitalization
 
                                        4
<PAGE>   5
 
firms that have generally exhibited above-average rates of growth in sales and
earnings over an extended period. Morgan Growth Fund may also invest in
"emerging growth companies"--expanding firms with generally smaller stock market
capitalizations. Finally, Morgan Growth Fund may hold investments in "cyclical
growth and other companies." These are firms which, while they may not have a
history of stable long-term growth, are nonetheless expected to represent
attractive investments.
 
  2. Advisory Fees
 
     The investment adviser to the Service Economy Portfolio is Wellington
Management Company ("WMC"). WMC also serves as investment adviser with respect
to approximately 40% of Morgan Growth Fund's assets. The remainder of Morgan
Growth Fund's assets are managed by Franklin Portfolio Associates (33%), Husic
Capital Management (13%) and Vanguard's Core Management Group (9%), with
approximately 5% of the Fund's net assets held in cash.
 
     The Service Economy Portfolio, along with the other portfolios of Vanguard
Specialized Portfolios ("VSP"), for which WMC serves as adviser (Health Care,
Technology, Energy and Utilities Income) pays an aggregate investment advisory
fee, at the end of each fiscal quarter, calculated by applying the following
annual percentage rates to the average month-end net assets for the quarter of
the five portfolios, as follows:
 
<TABLE>
<CAPTION>
                                     NET ASSETS                                       RATE
    -----------------------------------------------------------------------------    -------
    <S>                                                                              <C>
    First $100 million...........................................................     0.300%
    Next $150 million............................................................     0.200%
    Next $250 million............................................................     0.150%
    Next $500 million............................................................     0.125%
    Over $1 billion..............................................................     0.100%
</TABLE>
 
     The advisory fee is based on the net assets for the five Portfolios of VSP
for which WMC serves as adviser and is allocated to each Portfolio based on the
net assets of each Portfolio. For the fiscal year ended January 31, 1994, the
investment advisory fee represented an effective annual rate of .14 of 1% of
average net assets for each Portfolio. Matthew E. Megargel, Vice President of
WMC serves as portfolio manager of the Service Economy Portfolio.
 
     Morgan Growth Fund pays WMC a basic advisory fee calculated by applying
varying percentage rates to the average net assets of the fund managed by WMC as
follows:
 
<TABLE>
<CAPTION>
                                     NET ASSETS                                       RATE
    -----------------------------------------------------------------------------    -------
    <S>                                                                              <C>
    First $50 million............................................................     0.325%
    Next $100 million............................................................     0.225%
    Next $150 million............................................................     0.150%
</TABLE>
 
     This basic advisory fee may be increased or decreased by applying an
adjustment formula ("incentive/penalty fee") based on WMC's investment
performance relative to the investment record of the Growth Fund Stock Index
(the "Index") which is described in detail in the Morgan Growth Fund Prospectus.
 
                                        5

     The following table sets forth the incentive/penalty fee rates payable by
the Fund to WMC under the proposed investment advisory agreement:

             -12% or more below............................                -.075%
</TABLE>
 
     Accordingly, the maximum possible fee payable to WMC under the agreement
would be .40 of 1% of net assets and the minimum possible fee payable thereunder
would be .075 of 1% of net assets. Robert D. Rands, Senior Vice President of WMC
serves as portfolio manager of the assets of Morgan Growth Fund assigned to WMC.
 
     Morgan Growth Fund pays Franklin Portfolio Associates ("FPA") a basic
advisory fee calculated by applying varying percentage rates to the average net

    Next $200 million............................................................     0.200%
    Next $300 million............................................................     0.150%
</TABLE>
 
     The basic advisory fee may be increased or decreased by applying an
adjustment formula ("incentive/penalty fee") based on FPA's investment
performance relative to the Growth Fund Stock Index.

             -6% or more below.............................               -.100%
</TABLE>
 
     Accordingly, the maximum possible fee payable to FPA under the agreement
would be .35 of 1% of net assets and the minimum possible fee payable thereunder
would be .05 of 1% of net assets. John J. Nagorniak, President of FPA, serves as
portfolio manager of the assets of Morgan Growth Fund assigned to FPA.
 
     Morgan Growth Fund pays Husic Capital Management ("Husic") a basic advisory
fee at the end of each fiscal quarter, calculated by applying a quarterly rate,
based on the following annual percentage rates, to the average month-end assets
of the Morgan Growth managed by Husic for the quarter:

     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 assets managed by Husic (the "Husic Portfolio") relative to
the return of the Index.
 
     Effective with the quarter ending September 30, 1994, 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 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
equity investment managed by Husic.
 
     The incentive/penalty fee rates will be determined by measuring the
investment performance of the Husic Portfolio relative to the investment record
of the Index in accordance with the following table:

</TABLE>
 
     Until the Quarter ending September 30, 1996, the incentive/penalty fee for
Husic will be calculated according to the following transition rules:
 
     (a) Prior to June 30, 1994. For the quarters ending on or prior to June 30,
1994, the incentive/penalty fee adjustment will not be operable. The advisory
fee payable by the Fund shall be the basic fee, calculated as set forth above.
 
     (b) July 1, 1994 through September 30, 1996. Beginning with the quarter
ending September 30, 1994, and until the quarter ending September 30, 1996, the
incentive/penalty fee will be computed based upon a comparison of the investment
performance of the Husic Portfolio and that of the Growth Index over the number
of months that have elapsed between October 1, 1993 and the end of the quarter
for which the fee is computed. The number of percentage points by which the
investment performance of the Husic Portfolio
 
                                        7

     (c) On and After September 30, 1996. For the quarter ending September 30,
1996 and thereafter, the period used to calculate the incentive/penalty fee
shall be the 36 months preceding the end of the quarter for which the fee is
being computed and the number of percentage points used shall be 12.
 
     Accordingly, after the incentive/penalty fee is in full effect, the maximum
possible fee payable to Husic under the agreement would be .70 of 1% and the
minimum possible fee payable thereunder would be .10 of 1%. Frank Husic,
president of Husic, serves as portfolio manager for the assets of Morgan Growth
Fund managed by Husic.
 
     The remaining assets of Morgan Growth Fund are managed on an at-cost basis
by Vanguard's Core Management Group under the direction of George U. Sauter,
Vice President of Vanguard.
 
     For the fiscal year ended December 31, 1993, the aggregate investment
advisory fee paid by Morgan Growth Fund represented an effective annual base
rate of .18 of 1% of the Fund's net assets before a decrease of .03 of 1% based
on performance. The advisory fee rates paid to WMC, FPA and Husic for the 1993
fiscal year were as follows:

     The maximum possible advisory fee payable by the Service Economy Portfolio
would be .30 of 1% of net assets, while the maximum possible aggregate advisory
fee payable by Morgan Growth Fund would be .38 of 1% of net assets. However, at
current asset levels, the maximum possible aggregate advisory fee payable by
Morgan Growth Fund would be .28 of 1%.
 
  3. Management, Administrative and Distribution Services
 
     The Service Economy Portfolio and Morgan Growth Fund are members of The
Vanguard Group of Investment Companies. Through their jointly-owned subsidiary,
The Vanguard Group, Inc. ("Vanguard"), the member funds of the Vanguard Group
obtain at cost virtually all of their corporate management, administrative, and
distribution services. Each Fund pays its share of Vanguard's total expenses
relating to these services, which are allocated among the Funds under methods
approved by the Board of Directors of each Fund.
 
                                        8
<PAGE>   9
 
  4. Asset Size and Expense Ratios
 
     On March 1, 1994 the Service Economy Portfolio had total net assets of
approximately $34 million. On the same date, Morgan Growth Fund had total net
assets of approximately $1.1 billion. For the fiscal year ended January 31,
1994, the Service Economy Portfolio had an expense ratio of .41 of 1% of its
average net assets. The expense ratio for Morgan Growth Fund for its 1993 fiscal
year was .49 of 1% of its average net assets. Redemptions from Morgan Growth
Fund are not assessed the 1% redemption fee that is incurred by shareholders of
the Service Economy Portfolio upon redemption.
 
  5. Purchase, Redemption and Exchange Procedures
 
     Purchase procedures for the Service Economy Portfolio and Morgan Growth
Fund are virtually identical, and are described on page 16 of the Morgan Growth
Fund prospectus. Under normal circumstances redemptions from the Service Economy
Portfolio are assessed a 1% redemption fee. However, no fee will be charged for
the exchange of Service Economy Portfolio shares for Morgan Growth Fund shares.
Also, beginning on April 18, 1994, there will be no redemption fee applied on
redemptions from the Service Economy Portfolio. Morgan Growth Fund does not
charge a fee for redemptions. In addition, shareholders of both the Service
Economy Portfolio and Morgan Growth Fund may exchange shares for shares of other
Vanguard Funds by following the procedures described on page 21 of the Morgan
Growth Fund Prospectus which are identical to the existing procedures for the
Service Economy Portfolio with the exception that Morgan Growth Fund
shareholders are limited to two substantive exchange redemptions in any twelve
month period, while Service Economy Portfolio shareholders are allowed to make
three such exchanges.
 
  6. Income Dividends and Capital Gains Distributions
 
     Both the Service Economy Portfolio and Morgan Growth Fund pay income
dividends and distribute capital gains on an annual basis. Shareholders may
elect to accept such dividends in additional shares or take them in cash.
 
     If the proposal meets shareholder approval, the Service Economy Portfolio
will distribute all accumulated ordinary income and realized net capital gains
to shareholders of record on or about June 1, 1994. These distributions will be
subject to income taxes for the year in which distributed. For your reference,
the table below shows all realized net capital gains on a per share basis as of
March 31, 1994. The actual per share capital gains distribution will differ from
the figures below depending on portfolio management activity prior to the
distributions. Only those capital gains (net of realized capital losses) that
have been realized will be distributed prior to the merger. Unrealized capital
gains can become realized capital gains as a byproduct of portfolio management
activities.

RISK FACTORS
 
     Both the Service Economy Portfolio and Morgan Growth Fund invest
principally in common stocks with the objective of long-term capital
appreciation. The Service Economy Portfolio concentrates its investments in the
service economy industry, while Morgan Growth Fund is more broadly diversified
across several industries. The Service Economy Portfolio held 61 securities on
January 31, 1994, while Morgan Growth Fund held approximately 325 securities on
the same date.
 
THE PROPOSED REORGANIZATION
 
  1. The Agreement and Plan of Reorganization
 
     The Directors of the Service Economy Portfolio and Morgan Growth Fund,
including a majority of the independent Directors of each Fund, have determined
that the proposed reorganization is in the best interests of the shareholders of
each Fund. The Directors of each Fund, including a majority of the indepen-
 
                                       10
<PAGE>   11
 
dent Directors of each Fund, have further determined that the interest of
shareholders of each Fund will not be diluted as a result of the proposed
reorganization. The terms and conditions under which the proposed reorganization
may be consummated are set forth in the Agreement and Plan of Reorganization,
dated as of March 1, 1994, between the Service Economy Portfolio and Morgan
Growth Fund (the "Agreement"). The Agreement is attached as Exhibit I to this
Combined Proxy Statement and Prospectus. Significant provisions of the Agreement
are summarized elsewhere in this Combined Proxy Statement and Prospectus.
 
  2. The Closing Date
 
     The Agreement provides that Morgan Growth Fund will acquire substantially
all of the assets of the Service Economy Portfolio in exchange solely for shares
of Morgan Growth Fund to be issued to shareholders of the Service Economy
Portfolio on June 2, 1994, or such later date as may be agreed upon by the
parties (the "Closing Date"). The number of shares of Morgan Growth Fund to be
issued to shareholders of the Service Economy Portfolio will be determined on
the basis of the relative net assets per share of the two funds computed as of
the close of the New York Stock Exchange on the Closing Date. Immediately
following the Closing Date, the Service Economy Portfolio will dissolve and
distribute pro rata to its shareholders of record, as of the close of business
on the Closing Date, the shares of Morgan Growth Fund received by the Service
Economy Portfolio.
 
  3. Federal Income Tax Consequences
 
     Consummation of the reorganization is subject to the condition that the
Service Economy Portfolio and Morgan Growth Fund receive an opinion of counsel
to the effect that the reorganization will not result in a recognition of gain
or loss for Federal income tax purposes for either the Service Economy Portfolio
or Morgan Growth Fund, or their respective shareholders.
 
  4. Vote Required for Shareholder Approval of the Reorganization
 
     Approval of the Plan of Reorganization will require the affirmative vote of
a majority of the shares of common stock outstanding and entitled to vote at
this special meeting of shareholders.
 
            ADDITIONAL INFORMATION ABOUT THE PROPOSED REORGANIZATION
 
REASONS FOR THE PROPOSED REORGANIZATION
 
     The Service Economy Portfolio was formed as a member of The Vanguard Group
of Investment Companies in 1984, with the objective of providing long-term
capital appreciation by concentrating its investments in the service sector of
the economy. Over the period since its inception, the performance of the Service
Economy Portfolio has lagged that of competitive standards, as well as that of
the overall stock market. Additionally, investor interest in the Portfolio has
been modest, limiting the growth of the Portfolio. Consequently, the Service
Economy Portfolio's Board of Directors has determined that the expenses involved
in maintaining a separate Portfolio for this purpose are no longer warranted.
 
     Due to the Service Economy's focus on a particular sector of the economy,
the Portfolio's performance results have also fluctuated in a wider range than
many broadly diversified funds. Morgan Growth Fund does
 
                                       11
<PAGE>   12
 
not concentrate its investments in any single industry but invests in a
diversified portfolio of stocks covering many sectors of the economy. Thus,
Morgan Growth Fund provides shareholders of the Service Economy Portfolio a much
more broadly diversified portfolio. Morgan Growth Fund is similar to the Service
Economy Portfolio in several ways. After the merger, shareholders would still
maintain a significant interest in the service sector as Morgan Growth Fund
invests a substantial portion of its assets in the service sector of the
economy. In addition, the Morgan Growth Fund invests in companies covering a
wide range of market capitalizations. On average the market capitalization of
the two portfolios are similar. Both Portfolios emphasize growth stocks. The
respective investment returns of each Fund are as shown on page 19 under
"Performance Summary". The Service Economy Portfolio and approximately 40% of
the assets of Morgan Growth Fund are managed by WMC. Over longer-term periods,
the total return of the Service Economy Portfolio and Morgan Growth Fund have
been similar, however, Morgan Growth Fund has been less volatile, reflecting its
broader diversification.
 
     Given this background, the Officers and Directors of the Service Economy
Portfolio have carefully evaluated the Service Economy Portfolio's performance
record since inception, giving careful consideration to the risks and
opportunities of making changes. The Officers and Directors have concluded that
it would be in the best interest of the Portfolio and its shareholders that the
assets of the Portfolio be acquired by Morgan Growth Fund.
 
THE PLAN OF REORGANIZATION
 
     The Agreement provides that Morgan Growth Fund will acquire substantially
all of the assets of the Service Economy Portfolio in exchange solely for shares
of common stock ($.001 par value) of Morgan Growth Fund on the Closing Date,
June 2, 1994 or such later date as may be agreed upon by the parties. The number
of shares of Morgan Growth Fund to be issued to shareholders of the Service
Economy Portfolio will be determined on the basis of relative net asset values
per share of the two Funds computed as of the close of the New York Stock
Exchange on the Closing Date. The net asset value per share for each Fund will
be determined by dividing the total value of each Fund's investments and other
assets, less any liabilities, by the total of its outstanding shares using the
valuation procedures set forth under "The Fund's Share Price" on page 14 of the
accompanying Morgan Growth Fund Prospectus.
 
     As of the close of business on March 1, 1994, each share of the Service
Economy Portfolio was valued at $23.42 and each share of Morgan Growth Fund was
valued at $12.09, for purposes of computing the exchange ratio. Using this
value, a total of approximately 2,841,682 shares of Morgan Growth Fund would
have been issuable to the Service Economy Portfolio pursuant to the Agreement,
representing an exchange ratio of 1.94 shares of Morgan Growth Fund for each
share of the Service Economy Portfolio then outstanding. The computation of this
exchange ratio, had the transaction taken place on March 1, 1994, is set forth
as Appendix A to the Agreement.
 
     Immediately following the Closing Date, the Service Economy Portfolio will
dissolve and distribute pro rata to its shareholders of record as of the close
of business on the Closing Date, the shares of Morgan Growth Fund received by
the Service Economy Portfolio. Such liquidation and distribution will be
accomplished by the establishment of open accounts on the share records of
Morgan Growth Fund in the names of such Service Economy Portfolio shareholders
and representing the respective pro rata number of shares of Morgan Growth Fund
due such shareholders. Fractional shares of Morgan Growth Fund will be carried
to the
 
                                       12
<PAGE>   13
 
third decimal place. As promptly as practicable after the Closing Date, each
holder of any outstanding certificate or certificates representing shares of the
Service Economy Portfolio may surrender the same to The Vanguard Group, Inc., as
transfer agent for Morgan Growth Fund, and request in exchange therefore a
certificate representing the number of whole shares of Morgan Growth Fund into
which shares of the Service Economy Portfolio theretofore represented by the
certificate or certificates so surrendered shall have been converted. However,
no fractional share certificates will be issued. Morgan Growth Fund will issue
new certificates only upon written request. Until so surrendered, each
outstanding certificate, which, prior to the Closing Date, represented shares of
the Service Economy Portfolio shall be deemed for all purposes to evidence
ownership of the number of shares of Morgan Growth Fund into which the former
shares of the Service Economy Portfolio have been converted.
 
     The consummation of the Agreement is further subject to the customary
conditions applicable to corporate reorganizations of this type as set forth in
Section 8 of the Agreement. Moreover, the Agreement may be terminated and the
reorganization abandoned at any time, before or after consent of the two
parties, or by either party if any condition set forth in Section 8 has not been
fulfilled by the other party or waived by the party entitled to its benefits.
 
EXPENSES OF THE REORGANIZATION
 
     The Service Economy Portfolio and Morgan Growth Fund will each bear such
expenses of entering into and carrying out the provisions of the Agreement as
will be separately incurred by it. The expenses of Morgan Growth Fund will
include legal and accounting fees, and are expected to be minimal. The Service
Economy Portfolio expenses will include: the costs of the special meeting; proxy
costs (including all costs of solicitation, printing and mailing of this Proxy
Statement); the expenses of its proposed liquidation and dissolution; and legal
and accounting fees. It is estimated that these expenses will not exceed
$15,000.
 
TAX CONSEQUENCES
 
     Consummation of the proposed reorganization is conditioned upon receipt of
an opinion of Stradley, Ronon, Stevens and Young, counsel to the Service Economy
Portfolio and Morgan Growth Fund, that the acquisition will qualify as a
reorganization within the meaning of Section 368(a)(1)(c) of the Internal
Revenue Code of 1986, as amended, and that the proposed reorganization will not
result in the recognition of gain or loss for Federal income tax purposes for
either the Service Economy Portfolio, Morgan Growth Fund or their respective
shareholders. See Section 8(f ) of the Agreement.
 
SHAREHOLDERS' RIGHTS
 
     There are no material differences between the rights of the Service Economy
Portfolio's shareholders and the rights of Morgan Growth Fund's shareholders.
Morgan Growth Fund and the Service Economy Portfolio are each Maryland
corporations. Shares of both Funds are fully paid and nonassessable. Holders
thereof have noncumulative voting rights and equal rights with respect to
dividends, assets and liquidations, but no preemptive rights. Shareholders of
the Service Economy Portfolio will not be entitled to any "dissenters rights"
under Maryland law since the reorganization is between two open-end investment
companies registered under the Investment Company Act of 1940.
 
                                       13
<PAGE>   14
 
     However, shareholders who find that the proposed reorganization does not
meet their particular investment needs and objectives, may consider two
additional options: (1) exchanging their holdings without sales commissions into
another mutual fund in The Vanguard Group, currently offering its shares to new
investors, which is better suited to their goals; or (2) redeeming shares for
cash. These options are available to a Service Economy Portfolio shareholder
both before and, as a Morgan Growth Fund shareholder, after the reorganization.
Shareholders who exercise either of these options on or after April 18, 1994
will not be subject to the 1% redemption fee. Exchanges and redemptions are both
taxable events so either action will result in the realization of a capital gain
or capital loss to the shareholder, depending upon the original cost basis of
the shareholder's investment.

     The Fund pays FPA a basic advisory fee calculated by applying varying
percentage rates to the average net assets of the Fund managed by FPA as set
forth on page 6.

     The Fund pays Husic a basic advisory fee calculated by applying various
percentage rates to the average net assets of the Fund managed by Husic as set
forth on page 6.
 
     The basic advisory fees payable to WMC, FPA and Husic may be increased or
decreased by applying an adjustment formula ("incentive/penalty fee") based on
the respective adviser's performance relative to that of the Growth Fund Stock
Index as set forth beginning on page 6.
 
     The investment performance of Morgan Growth Fund for any period, expressed
as a percentage of Morgan Growth Fund's net asset value per share at the
beginning of such period, is the sum of: (i) the change in Morgan Growth Fund's
net asset value per share during such period; (ii) the value of Morgan Growth
Fund'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 Morgan Growth Fund for undistributed realized
long-term capital gains. The investment record of the Growth Stock Fund Index
for any period, expressed as a percentage of the Growth Fund Stock Index level
at the beginning of such period, is 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 all subject to and in accordance with any
then applicable rules of the Securities and Exchange Commission.
 
     For the purpose of determining the fee adjustment for investment
performance, the net assets of Morgan Growth Fund are averaged over the same
period as the investment performance of Morgan Growth Fund and the investment
record of the Growth Fund Stock Index are computed.
 
     During the three fiscal years ended December 31, 1993, Morgan Growth Fund
paid WMC the following advisory fees:

     For the period June 28, 1993 to December 31, 1993, the Fund paid Husic an
advisory fee of $140,254.
 
     The present agreements with WMC and FPA continue until April 23, 1994 and
the present agreement with Husic continues until September 30, 1995. The
agreements are renewable thereafter for successive one year periods, only if
each renewal is specifically approved by a vote of the Board of Directors,
including the
 
                                       16
<PAGE>   17
 
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. The agreements are automatically terminated if
assigned, and may be terminated without penalty at any time (1) either by vote
of the Board of Directors of the Fund, or (2) by WMC, FPA and Husic upon 90 days
written notice to Morgan Growth Fund.
 
INVESTMENT LIMITATIONS
 
     The investment limitations for Morgan Growth Fund summarized on page 7 of
the Prospectus are substantially identical to those applicable to the Service
Economy Portfolio. These investment limitations may not be changed without
shareholder approval except that Morgan Growth Fund is prohibited from investing
more than 25% of its assets in any one industry.
 
PORTFOLIO BROKERAGE
 
     The portfolio brokerage policies of the Service Economy Portfolio and
Morgan Growth Fund are identical. In this respect the investment advisory
agreements for each Fund authorize the investment advisers, with the approval of
such 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 investment advisers to use their best efforts to obtain the best available
price and most favorable execution with respect to all transactions for the
Fund. The investment advisers have undertaken to execute each investment
transaction at a price and commission which provides the most favorable total
cost or proceeds obtainable under the circumstances.
 
     In placing portfolio transactions, the investment advisers 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 are considered in making these
determinations. In those instances where it is reasonably determined that more
than one broker can offer the brokerage services needed to obtain the best
available price and most favorable execution, consideration may be given to
those brokers who supply investment research and statistical information and
provide other services in addition to execution services to the Fund and/or the
investment advisers. Each investment adviser considers the investment services
it receives 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.
 
     Each 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, the investment adviser may
cause the Fund to pay a broker-dealer which furnishes brokerage and research
services at 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 investment adviser to the Fund and the other
Funds in the Group.
 
     Currently, it is Morgan Growth Fund's policy that the investment 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. Each investment adviser will
pay such higher commissions only if it believes this to be in the best interest
of the Fund. Some brokers or dealers who
 
                                       17
<PAGE>   18
 
may receive such higher commissions in recognition of brokerage services related
to execution of securities transactions are also providers of research
information to the investment adviser and/or the Fund. However, each investment
adviser has informed the Fund that it will not pay higher commission rates
specifically for the purpose of obtaining research services.
 
     Since each Fund does not market its shares through intermediary brokers or
dealers, it is not Morgan Growth Fund's practice to allocate brokerage or
principal business on the basis of sales of its shares which may be through such
firms. However, each Fund may place portfolio orders with qualified brokers or
dealers who recommend the Fund to clients, or who act as agent in the purchase
of shares of Morgan Growth Fund 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 brokers or dealers.
 
     During the fiscal year ended January 31, 1994, the Service Economy
Portfolio paid approximately $30,000 in brokerage commissions and had a
portfolio turnover rate of 29%. During the fiscal year ended December 31, 1993,
Morgan Growth Fund paid approximately $1,577,672 in brokerage commissions, and
had a portfolio turnover rate of 72%.
 
THE VANGUARD GROUP
 
     The Service Economy Portfolio and Morgan Growth Fund are members of The
Vanguard Group of Investment Companies. Through their jointly-owned subsidiary,
The Vanguard Group, Inc., the member Funds obtain at cost virtually all of their
corporate management, administrative and distribution services. See page 8 of
the Morgan Growth Fund Prospectus.
 
LITIGATION
 
     Neither the Service Economy Portfolio nor Morgan Growth Fund is involved in
any litigation.

                              PERFORMANCE SUMMARY
 
     The following table shows the investment results of the Service Economy
Portfolio and Morgan Growth Fund as compared to changes in the unmanaged
Standard & Poor's 500 Composite Stock Price Index (the "S&P 500"). This
comparison is designed to provide an historical basis for evaluation of the
proposed reorganization by covering the relative investment performance of the
Service Economy Portfolio, Morgan Growth Fund and the S&P 500 since the
inception of the Service Economy Portfolio. The results shown represent "total
return" investment performance which assumes the reinvestment of all capital
gains and income dividends for the indicated periods. The investment performance
should be considered in light of each Fund's investment objectives and policies,
the characteristics and quality of each Fund's investments, and the period
selected. Future investment results cannot be predicted.

                      AGREEMENT AND PLAN OF REORGANIZATION
 
     AGREEMENT AND PLAN OF REORGANIZATION, made as of this 1st day of March,
1994, by and between Vanguard Specialized Portfolios, Inc. (hereinafter called

Inc. (hereinafter called "Vanguard/Morgan Growth"), a Maryland corporation, with
its principal place of business at 100 Vanguard Boulevard, Malvern, Pennsylvania
19355.
 
                             PLAN OF REORGANIZATION
 
     The reorganization (hereinafter referred to as the "Plan of
Reorganization") will consist of (i) the acquisition by Vanguard/Morgan Growth
Fund of substantially all of the property, assets and goodwill of the class of
shares of VSP known as the Service Economy Portfolio (the "Service Economy
Portfolio") in exchange solely for shares of common stock, $.001 par value per
share, of Vanguard/Morgan Growth Fund, (ii) the distribution of such shares of
Vanguard/Morgan Growth Fund common stock to the stockholders of the Service
Economy Portfolio according to their respective interests, and (iii) the
dissolution of the Service Economy Portfolio as soon as practicable after the
closing provided for in Section 3, all upon and subject to the terms and
conditions of the Agreement hereinafter set forth.
 
                                   AGREEMENT
 
     In order to consummate the Plan of Reorganization and in consideration of
the premises and of the covenants and agreements hereinafter set forth, the
parties hereto covenant and agree as follows:
 
1. SALE AND TRANSFER OF ASSETS, LIQUIDATION AND DISSOLUTION OF THE SERVICE
ECONOMY PORTFOLIO
 
     a. The Service Economy Portfolio agrees that it will convey, transfer and
deliver to Vanguard/Morgan Growth Fund at the closing provided for in Section 3
(hereinafter called the "Closing") all of its then existing assets free and
clear of all liens, encumbrances and claims whatsoever, except for cash or bank
deposits in an amount necessary to pay: (1) its costs and expenses of carrying
out this Agreement (including but not limited to fees of counsel and
accountants, its income dividend payable prior to the Closing Date, and expenses
of its liquidation and dissolution contemplated hereunder); (2) to discharge its
unpaid liabilities on its books at the Closing Date; and (3) to pay such
contingent liabilities as the directors shall reasonably deem to exist against
the Service Economy Portfolio, if any, at the Closing Date, for which contingent
and other appropriate liability reserves shall be established on the Service
Economy Portfolio's books. Any unspent portion of such funds retained shall be
delivered to Vanguard/Morgan Growth Fund upon dissolution of the Service Economy
Portfolio.
 
     b. Subject to the terms and conditions of this Agreement and in reliance on
the representations and warranties of the Service Economy Portfolio herein
contained, and in consideration of such sale, conveyance, transfer and delivery,
Vanguard/Morgan Growth Fund agrees at the Closing to deliver to the Service
Economy Portfolio the number of shares of common stock of the Vanguard/Morgan
Growth Fund ($.10 par value) determined as set forth in Section 2 hereof.
<PAGE>   24
 
     c. Immediately following the Closing Date, the Service Economy Portfolio
will liquidate and distribute pro rata to its stockholders of record as of the
close of business on the Closing Date, the shares of Vanguard/Morgan Growth Fund
common stock received by the Service Economy Portfolio pursuant to this Section
1. Such liquidation and distribution will be accompanied by the establishment of
open accounts on the stock records of Vanguard/Morgan Growth Fund in the names
of such stockholders of the Service Economy Portfolio representing the
respective pro rata number of Vanguard/Morgan Growth Fund shares due such
stockholders. Fractional shares of Vanguard/Morgan Growth's common stock will be
carried to the third decimal place. As promptly as practicable after the Closing
Date, each holder of any outstanding certificate or certificates theretofore
representing shares of common stock of the Service Economy Portfolio may
surrender the same to a Transfer Agent designated by Vanguard/Morgan Growth Fund
and request in exchange therefore a certificate or certificates representing the
number of whole and fractional shares of common stock of Vanguard/Morgan Growth
into which the shares of common stock of the Service Economy Portfolio
theretofore represented by the certificate or certificates so surrendered shall
have been converted. Certificates for fractional shares of Vanguard/Morgan
Growth will not be issued, however, but shall continue to be carried for the
open account of such stockholder. Until so surrendered, each outstanding
certificate which, prior to the Closing Date, represented common stock of the
Service Economy Portfolio shall be deemed for all corporate purposes to evidence
ownership of the number of shares of common stock of Vanguard/Morgan Growth into
which the common stock of the Service Economy Portfolio (which, prior to the
Closing Date, were represented thereby) have been so converted.
 
     d. As promptly as practicable after the liquidation of the Service Economy
Portfolio as aforesaid, the Service Economy Portfolio shall be dissolved
pursuant to the provisions of the General Laws of the State of Maryland and its
legal existence shall be terminated as provided therein.
 
2. EXCHANGE RATIO
 
     a. The value of the Service Economy Portfolio's assets to be acquired by
Vanguard/Morgan Growth Fund hereunder shall be the net asset value computed as
of the close of business (close of the New York Stock Exchange) on the Closing
Date, using the valuation procedures set forth in Vanguard/Morgan Growth Fund's
registration statement under the Securities Act of 1933.
 
     b. The total net assets of the Service Economy Portfolio determined under
(a) shall be divided by the number of shares of its outstanding common stock,
excluding treasury shares, to determine the Service Economy Portfolio's net
asset value per share as of the close of business on the Closing Date.
 
     c. The net asset value of a Vanguard/Morgan Growth share of common stock
shall be determined to the nearest full cent as of the close of business on the
Closing Date, using the valuation as set forth in Vanguard/Morgan Growth Fund's
registration statement under the Securities Act of 1933.
 
     d. The net asset value per share for the Service Economy Portfolio as
determined in (b) shall then be divided by the Vanguard/Morgan Growth net asset
value per share as determined in (c) to determine the exchange ratio. See
Appendix A to this Agreement for an example of how to determine the exchange
ratio.

mutually agree. The Closing shall take place at the principal office of
Vanguard/Morgan Growth Fund, 100 Vanguard Boulevard, Malvern Pennsylvania 19355,

Economy Portfolio shall deliver at the Closing a list of names and addresses of
the stockholders of the Service Economy Portfolio and the number of shares owned
by each such stockholder, indicating thereon which such shares are represented
by outstanding certificates and which by open accounts, all as of the close of
business on the Closing Date, certified by its Transfer Agent. Vanguard/Morgan
Growth Fund shall issue and deliver a certificate or certificates evidencing the
shares of Vanguard/Morgan Growth's common stock to be delivered at the Closing
to said Transfer Agent registered in such manner as the Service Economy
Portfolio may request, or provide evidence satisfactory to the Service Economy
Portfolio that such shares of Vanguard/Morgan Growth's common stock have been
registered in an open account on the books of Vanguard/Morgan Growth Fund in

YIELD AND                 From time-to-time the Fund may advertise its yield and total return.
TOTAL RETURN              Both yield and total return figures are based on historical earnings
                          and are not intended to indicate future performance. The "total return"
                          of the Fund refers to the average annual compounded rates of return
                          over one-, five-and ten-year periods or for the life of the Fund (as
                          stated in the advertisement) that would equate an initial amount
                          invested at the beginning of a stated period to the ending redeemable
                          value of the investment, assuming the reinvestment of all dividend and
                          capital gains distributions.
                          The "30-day yield" of the Fund is calculated by dividing net investment
                          income per share earned during a 30-day period by the net asset value
                          per share on the last day of the period. Net investment income includes
                          interest and dividend income earned on the Fund's securities; it is net
                          of all expenses and all recurring and nonrecurring charges that have
                          been applied to all shareholder accounts. The yield calculation assumes
                          that net investment income earned over 30 days is compounded monthly
                          for six months and then annualized. Methods used to calculate
                          advertised yields are standardized for all stock and bond mutual funds.
                          However, these methods differ from the accounting methods used by the
                          Fund to maintain its books and records, and so the advertised 30-day
                          yield may not fully reflect the income paid to your own account or the
                          yield reported in the Fund's reports to shareholders.

INVESTMENT                The Fund is an open-end diversified investment company. The objective
OBJECTIVE                 of the Fund is to provide long-term growth of capital by investing
                          primarily in common stocks. Dividend income is incidental to this
                          objective. There is no assurance that the Fund will achieve its stated
                          objective.
- -------------------------------------------------------------------------------------------------
INVESTMENT                The Fund invests primarily in the equity securities of growth
POLICIES                  companies. Under normal circumstances, at least 65% of the Fund's
THE FUND INVESTS          assets will be invested in such securities. The Fund is managed without
PRIMARILY IN              regard to tax ramifications. The Fund will generally invest in a
"GROWTH STOCKS"           diversified portfolio of common stocks but may also, from time-to-time,
                          hold securities that are convertible into common stocks.
                          The Fund is expected to invest a majority of its assets in "established
                          growth companies" -- i.e., larger capitalization firms that have
                          generally exhibited above-average rates of growth in sales and earnings
                          over an extended period. The Fund may also invest in "emerging growth
                          companies" -- expanding firms with generally smaller stock market
                          capitalizations. Finally, the Fund may hold investments in "cyclical
                          growth and other companies." These are firms which, while they may not
                          have a history of stable long-term growth, are nonetheless expected to
                          represent attractive investments.
                          The Fund employs three investment advisers, each of which independently
                          chooses common stock investments for the Fund. Wellington Management
                          Company, which is currently responsible for approximately two-thirds of
                          the Fund's equity investments, utilizes traditional methods of security
                          selection, including fundamental company research and relative
                          valuation techniques, in selecting growth stocks for the Fund. In
                          contrast, Franklin Portfolio Associates Trust and Roll and Ross Asset
                          Management Corporation, which are each responsible for approximately
                          one-sixth of the Fund's equity investments, are "quantitative"
                          investment managers. They utilize computerized techniques designed to
                          track -- and, if possible, outperform -- the returns of a specific
                          standard, the Growth Fund Stock Index. The Growth Fund Stock Index, a
                          benchmark calculated by Morningstar, Inc., is a measure of the
                          composite performance of the common stock holdings of the 50 largest
                          growth mutual funds.
                          In addition to investing in common stocks, the Fund is also authorized
                          to invest in certain short-term fixed income securities as cash
                          reserves and to use stock index futures and options to a limited
                          extent. See "Implementation of Policies" for a description of these and
                          other investment practices of the Fund.
                          The investment objective and policies of the Fund are not fundamental
                          and so may be changed by the Board of Directors without shareholder
                          approval. However, shareholders would be notified prior to a material
                          change in either.

                          As shown, from 1926 to 1992, common stocks have provided an average
                          annual total return (capital appreciation plus dividend income) of
                          +12.2%. While this average return can be used as a guide for setting
                          reasonable expectations for future stock market returns, it may not be
                          useful for forecasting future returns in any particular period, as
                          stock returns are quite volatile from year-to-year.
                          The chart above should not be viewed as a representation of future
                          investment performance of the stock market or the Fund. The illustrated
                          returns represent historical investment performance, which may be a
                          poor guide to future returns. Also, stock market indexes are based on
                          unmanaged portfolios of securities before transaction costs and other
                          expenses. Such costs reduce the relative performance of the Fund and
                          other "real world" portfolios. Finally, given its emphasis on "growth
                          stock" investments, the Fund is likely to differ significantly in terms
                          of portfolio composition and investment performance from broad market
                          averages like the S&P 500.
- -------------------------------------------------------------------------------------------------
WHO SHOULD                The Fund is designed for investors who have the perspective, patience
INVEST                    and financial ability to assume above-average interim investment risk
INVESTORS SEEKING         in pursuit of long-term capital growth. Because of the risks associated
LONG-TERM GROWTH          with common stock investments, the Fund is intended to be a long-term
                          investment vehicle and is not designed to provide investors with a
                          means of speculating on short-term stock market movements. Since the
                          Fund will focus on common stocks that offer below-average levels of
                          current income, greater-than-average investment risk -- for a common
                          stock fund -- is likely. The Fund's share price is expected to be
                          volatile.
                          No assurance can be given that the Fund will attain its objective or
                          that shareholders will be protected from the risk of loss that is
                          inherent in equity investing. Investors may wish to reduce the
                          potential risk of investing in the Fund by purchasing shares on a
                          periodic basis (dollar-cost averaging) rather than making an investment
                          in one lump sum.

                          Investors should not consider the Fund a complete investment program,
                          but should also maintain holdings in investments with different risk
                          characteristics, such as bonds and money market instruments. Investors
                          may also wish to complement an investment in the Fund with other types
                          of common stock investments.
- -------------------------------------------------------------------------------------------------
IMPLEMENTATION            The Fund follows a number of distinctive investment practices in an
OF POLICIES               effort to achieve its investment objective.
A PORTION OF THE          Two of the Fund's investment advisers, Franklin Portfolio Associates
FUND'S ASSETS ARE         Trust ("FPA") and Roll and Ross Asset Management Corporation ("R&R"),
MANAGED USING             use quantitative investment techniques in managing their respective
QUANTITATIVE              portions of the Fund's common stock investments. For the portfolio of
TECHNIQUES                securities they manage, FPA and R&R independently seek to track and, if
                          possible, outperform the investment returns of the Growth Fund Stock
                          Index. Currently, FPA and R&R are each responsible for approximately
                          one-sixth of the Fund's equity investments.
                          The Growth Stock Fund Index (the "Index") represents the composite
                          common stock portfolio of the 50 largest growth mutual funds, as
                          calculated by Morningstar, Inc. ("Morningstar"), an independent company
                          which provides mutual fund statistics. The 50 mutual funds included in
                          that Index are determined annually (as of December 31) by Morningstar.
                          For the two quantitative investment managers (FPA and R&R), the Index
                          is an essential tool in developing portfolios that will be designed to
                          track and, hopefully, outperform the Index. For Wellington Management
                          Company, the composition of the Index serves as a guideline for setting
                          portfolio policy. For all three investment advisers, the Index is
                          utilized as a benchmark for determining incentive/penalty investment
                          advisory fees. See "Investment Advisers" and the Statement of
                          Additional Information for further information on the Index and its use
                          as a benchmark for incentive/penalty fees.
THE FUND MAY INVEST       Although it normally seeks to remain substantially fully invested in
IN SHORT-TERM FIXED       equity securities, the Fund may invest temporarily in certain
INCOME SECURITIES         short-term fixed income securities. Such securities may be used to
                          invest uncommitted cash balances, to maintain liquidity to meet
                          shareholder redemptions, or to take a temporarily defensive position
                          against potential stock market declines. These securities include:
                          obligations of the United States Government and its agencies or
                          instrumentalities; commercial paper, bank certificates of deposit, and
                          bankers' acceptances; and repurchase agreements collateralized by these
                          securities. Approximately 5% of the Fund's net assets are expected to
                          be held as cash reserves, which will be managed by The Vanguard Group,
                          Inc. at no charge to the Fund.
THE FUND MAY USE          The Fund may utilize stock futures contracts and options to a limited
FUTURES CONTRACTS         extent. Specifically, the Fund may enter into futures contracts
AND OPTIONS               provided that not more than 5% of its assets are required as a futures
                          contract deposit. In addition, the Fund may enter into futures
                          contracts and options transactions only to the extent

                          that obligations under such contracts or transactions represent not
                          more than 20% of the Fund's assets.
                          Futures contracts and options may be used for several reasons: to
                          maintain cash reserves while remaining fully invested, to facilitate
                          trading, to reduce transaction costs, or to seek higher investment
                          returns when a futures contract is priced more attractively than the
                          underlying equity security or index. The Fund may not use futures
                          contracts or options transactions to leverage its net assets.
THE FUND MAY LEND         The Fund may lend its investment securities on a short-term basis (less
ITS SECURITIES            than nine months) to qualified institutional investors for the purpose
                          of realizing additional income. Loans of securities by the Fund will be
                          collateralized by cash, letters of credit, or securities issued or
                          guaranteed by the U.S. Government or its agencies. The collateral will
                          equal at least 100% of the current market value of the loaned
                          securities.
BORROWING                 The Fund may borrow money, subject to the limits set forth on page 7,
                          for temporary or emergency purposes, including the meeting of
                          redemption requests which might otherwise require the untimely
                          disposition of securities.
PORTFOLIO TURNOVER        Although it generally seeks to invest for the long term, the Fund
IS NOT EXPECTED TO        retains the right to sell securities irrespective of how long they have
EXCEED 100%               been held. It is anticipated that the annual portfolio turnover of the
                          Fund will not exceed 100%. A turnover rate of 100% would occur, for
                          example, if all of the securities of the Fund were replaced within one
                          year.
- -------------------------------------------------------------------------------------------------
INVESTMENT                The Fund has adopted certain limitations on its investment practices.
LIMITATIONS               Specifically, the Fund will not:
THE FUND HAS ADOPTED      (a) with respect to 75% of the value of its total assets, invest more
CERTAIN FUNDAMENTAL       than 5% of its assets in the securities of any single company;
LIMITATIONS               (b) with respect to 75% of the value of its total assets, purchase more
                          than 10% of the voting securities of any issuer;
                          (c) invest more than 25% of its assets in any one industry; and
                          (d) borrow money, except from banks (or through repurchase agreements)
                          for temporary or emergency (not leveraging) purposes, and then not in
                              an amount exceeding 10% of the value of the Fund's net assets at
                              the time the borrowing is made. Whenever borrowing exceeds 5% of
                              the value of the Fund's net assets, the Fund will not make any
                              additional investments.
                          These investment limitations are considered at the time investment
                          securities are purchased. The limitations described here and in the
                          Statement of Additional Information may be changed only with the
                          approval of a majority of the Fund's shareholders.

MANAGEMENT                The Fund is a member of The Vanguard Group of Investment Companies, a
OF THE FUND               family of 33 investment companies with 71 distinct mutual fund
VANGUARD ADMINISTERS      portfolios and total assets in excess of $100 billion. Through their
AND DISTRIBUTES           jointly owned subsidiary, The Vanguard Group, Inc. ("Vanguard"), the
THE FUND                  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. As a result of Vanguard's unique corporate
                          structure, the Vanguard Funds have costs substantially lower than those
                          of most competing mutual funds. In 1992, the average expense ratio
                          (annual costs including advisory fees divided by total net assets) for
                          the Vanguard Funds amounted to .31% compared to an average of 1.03% for
                          the mutual fund industry (data provided by Lipper Analytical Services).
                          The Officers of the Fund manage its day-to-day operations and are
                          responsible to the Fund's Board of Directors. The Directors set broad
                          policies for the Fund and choose its Officers. A list of the Directors
                          and Officers of the Fund and a statement of their present positions and
                          principal occupations during the past five years can be found in the
                          Statement of Additional Information.
                          Vanguard employs a supporting staff of management and administrative
                          personnel needed to provide the requisite services to the Funds and
                          also furnishes the Funds with necessary office space, furnishings and
                          equipment. Each Fund pays its share of Vanguard's 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.
                          Vanguard provides distribution and marketing services to the Funds. The
                          Funds are available on a no-load basis (i.e., there are no sales
                          commissions or 12b-1 fees). However, each Fund bears its share of the
                          Group's distribution costs.

INVESTMENT                The Fund currently employs three investment advisers: Wellington
ADVISERS                  Management Company ("WMC"), 75 State Street, Boston, MA 02109; Franklin
THE FUND EMPLOYS          Portfolio Associates Trust ("FPA"), One Post Office Square, Boston, MA
THREE INDEPENDENT         02109; and Roll and Ross Asset Management Corporation ("R&R"), 585
INVESTMENT ADVISERS       Skippack Pike, Blue Bell, PA 19422. Prior to April 24, 1990, WMC was
                          the sole investment adviser to the Fund (then known as W.L. Morgan
                          Growth Fund). FPA and R&R were added as advisers to the Fund on that
                          date.
                          The proportion of the net assets of the Fund managed by each adviser
                          was established by the Board of Directors, and may be changed in the
                          future by the Board of Directors as circumstances warrant. Presently
                          WMC is responsible for approximately two-thirds of the equity
                          investments of the Fund; FPA and R&R are each responsible for
                          one-sixth. (The cash portion of the Fund's net assets is managed by The
                          Vanguard Group, Inc. at no charge to the Fund.)

                          The Fund has entered into investment advisory agreements with WMC, FPA,
                          and R&R which provide that the advisers manage the investment and
                          reinvestment of the Fund's assets and continuously review, supervise
                          and administer the Fund's investment program. The advisers discharge
                          their responsibilities subject to the control of the Officers and
                          Directors of the Fund.
. . .WELLINGTON           WMC is a professional investment advisory firm which globally provides
MANAGEMENT                services to investment companies, institutions, and individuals. Among
COMPANY (WMC)             the clients of WMC are 12 of the 33 investment companies of The
                          Vanguard Group. As of December 31, 1992, WMC held discretionary
                          management authority with respect to approximately $67.4 billion of
                          assets. WMC and its predecessor organizations have provided advisory
                          services to investment companies since 1933 and to investment
                          counseling clients since 1960.
                          Frank V. Wisneski and Nancy T. August, Senior Vice Presidents of WMC,
                          serve as portfolio managers of the assets of the Fund assigned to WMC.
                          Each separately oversees one-half of the assets assigned to WMC. Mr.
                          Wisneski, who has been employed at WMC for 21 years, served as the sole
                          portfolio manager of the Fund from September 1979 to December 1989. At
                          that time, the responsibility for approximately one-half of the Fund's
                          assets was transferred to Ms. August. In addition to her work for the
                          Fund, Ms. August, who has also been employed at WMC for 21 years,
                          oversees various investment portfolios with objectives and policies
                          similar to those of the Fund. In managing the assets assigned to WMC,
                          Mr. Wisneski and Ms. August are supported by research and other
                          investment services provided by the professional staff of WMC.
                          The Fund pays WMC a basic advisory fee calculated by applying varying
                          percentage rates to the average net assets of the Fund managed by WMC.
                          The basic fee schedule is as follows:

                        Over $150 million      0.150%
                          This basic advisory fee may be increased or decreased by applying an
                          adjustment formula ("incentive/penalty fee") based on WMC's investment
                          performance relative to the investment record of Growth Fund Stock
                          Index. Under the incentive/ penalty fee schedule, the basic fee payable
                          to WMC may be increased or decreased by as much as .075% depending on
                          the investment performance of the equity investments managed by WMC.
                          Prior to April 24, 1990 WMC served as sole investment adviser to the
                          Fund. At that time the Standard & Poor's 500 Composite Stock Price
                          Index (the "S&P 500") was used as the benchmark for determining any
                          incentive/penalty fee paid to WMC. However, while the S&P 500 does
                          serve as a broad gauge of stock market

                          "growth stocks," the primary investments of the Fund. To assess the
                          performance of its advisers relative to comparable "growth stock"
                          investments, the Fund has adopted as a benchmark for incentive/penalty
                          fees the Growth Fund Stock Index, an index of the equity holdings of
                          the 50 largest growth stock mutual funds.
                          Under rules of the Securities and Exchange Commission, the
                          incentive/penalty fee will not be fully operable until the quarter
                          ending June 30, 1993, and, until that date, will be calculated
                          according to certain transition rules. See the Statement of Additional
                          Information for a detailed description of the incentive/penalty fee

                          R&R employs proprietary computer models in selecting individual equity
                          securities and in structuring investment portfolios for its clients,
                          including the Fund. Richard W. Roll, Co-Chairman of R&R, has been
                          designated as the portfolio manager of the assets of the Fund assigned
                          to R&R; he is responsible for overseeing the application of R&R's
                          quantitative techniques to those assets. Mr. Roll and the other
                          investment principals of R&R are responsible for the ongoing
                          development enhancement of R&R's quantitative investment techniques.
                          The Fund pays R&R a basic advisory fee calculated by applying varying
                          percentage rates to the average net assets of the Fund managed by R&R.
                          The basic fee schedule is as follows:

                        First $150 million     0.400%
                        Next $100 million      0.200%
                        Over $250 million      0.100%
                          This basic advisory fee may be increased or decreased by applying an
                          incentive/ penalty fee based on R&R's investment performance relative
                          to the investment record of the Growth Fund Stock Index. Under the
                          incentive/penalty fee schedule, the basic fee payable to R&R may be
                          increased or decreased by as much as .05% to .20%, depending on the
                          dollar amount and the relative performance of the equity investments
                          managed by R&R. Moreover, the incentive/penalty fee schedule is
                          structured in such a way that, in order to earn the basic fee, the
                          investment performance of R&R's equity assets must exceed that of the
                          Index by at least 6% over the preceding 36 month period.

                          Under rules of the Securities and Exchange Commission, the
                          incentive/penalty fee structure will not be fully operable until the
                          quarter ending June 30, 1993, and, until that date, will be calculated
                          according to certain transition rules. See the Statement of Additional
                          Information for a detailed description of the incentive/ penalty fee
                          schedule for R&R and the applicable transition rules.
                          For the fiscal year ended December 31, 1992, the aggregate investment
                          advisory fees paid by Vanguard/Morgan Growth Fund to WMC, FPA and R&R
                          represented an effective annual rate of .21 of 1% of average net
                          assets, before a net decrease of .02 of 1% based on performance. The
                          investment advisory fees paid by the Fund for this period to WMC, FPA
                          and R&R represented an effective annual rate of .17%, .23% and .22% of
                          1%, respectively, of the average net assets managed by WMC, FPA and
                          R&R.
                          The investment advisory agreements with WMC, FPA and R&R authorize the
                          advisers to select brokers or dealers to execute the purchase and sale
                          of the Fund's portfolio securities, and direct the advisers to use
                          their best efforts to obtain the best available price and most
                          favorable execution with respect to all transactions. The full range
                          and quality of brokerage services available are considered in making
                          their determinations.
                          The Fund has authorized WMC, FPA and R&R to pay higher commissions in
                          recognition of brokerage services felt necessary for the achievement of
                          better execution, provided the advisers believe this to be in the best
                          interests of the Fund. Although the Fund does not market its shares
                          through intermediary brokers or dealers, the Fund's advisers may place
                          orders with qualified broker-dealers who recommend the Fund to clients
                          if the Officers of the Fund believe that the quality of the transaction
                          and the commission are comparable to what they would be with other
                          qualified brokerage firms.

PERFORMANCE               The table below provides investment results for the Fund for several
RECORD                    periods throughout the Fund's lifetime. The results shown represent
                          "total return" investment performance, which assumes the reinvestment
                          of all capital gains and income dividends for the indicated periods.
                          Also included is comparative information with respect to the unmanaged
                          Standard & Poor's 500 Composite Stock Price Index, a widely-used
                          barometer of stock market activity, and the Consumer Price Index, a
                          statistical measure of changes in the prices of goods and services. The
                          tables do not make any allowance for federal, state or local income
                          taxes, which shareholders must pay on a current basis.
                          The results should not be considered a representation of the total
                          return from an investment made in the Fund today. This information is
                          provided to help investors better understand the Fund and may not
                          provide a basis for comparison with other investments or mutual funds
                          which use a different method to calculate performance.

DIVIDENDS,                The Fund expects to pay dividends annually from ordinary income. Net
CAPITAL GAINS             capital gains distributions, if any, will also be made annually.
AND TAXES                 Dividend and capital gains distributions may be automatically
THE FUND PAYS             reinvested or received in cash. See "Choosing a Distribution Option"
DIVIDENDS AND ANY         (page 15) for a description of these distribution methods.
CAPITAL GAINS             In order to satisfy certain requirements of the Tax Reform Act of 1986,
ANNUALLY                  the Fund may declare special year-end dividend and capital gains
                          distributions during December. Such distributions, if received by
                          shareholders by January 31, are deemed to have been paid by the Fund
                          and received by shareholders on December 31 of the prior year.
                          The Fund intends to qualify for taxation as a "regulated investment
                          company" under the Internal Revenue Code so that it will not be subject
                          to federal income tax to the extent its income is distributed to
                          shareholders. Dividends paid by the Fund from net investment income,
                          whether received in cash or reinvested in additional shares, will be
                          taxable to shareholders as ordinary income. For corporate investors,
                          dividends from net investment income will generally qualify in part for
                          the intercorporate dividends-received deduction. However, the portion
                          of the dividends so qualified depends on the aggregate taxable
                          qualifying dividend income received by the Fund from domestic (U.S.)
                          sources.
                          Distributions paid by the Fund from long-term capital gains, whether
                          received in cash or reinvested in additional shares, are taxable as
                          long-term capital gains, regardless of the length of time you have
                          owned shares in the Fund. Capital gains distributions are made when the
                          Fund realizes net capital gains on sales of portfolio securities during
                          the year. The Fund does not seek to realize any particular amount of
                          capital gains during a year; rather, realized gains are a byproduct of
                          portfolio management activities. Consequently, capital gains distri-
                          butions may be expected to vary considerably from year-to-year. There
                          will be no capital gains distributions in years when the Fund realizes
                          net capital losses.
                          Note that if you accept capital gains distributions in cash, instead of
                          reinvesting them in additional shares, you are in effect reducing the
                          capital at work for you in the Fund. Also, keep in mind that if you
                          purchase shares in the Fund shortly before

                          receiving them in cash.

A CAPITAL GAIN OR         A sale of shares of the Fund is a taxable event, and may result in a

                          local taxes.
                          The Fund is required to withhold 31% of taxable dividends, capital
                          gains distributions, and redemptions paid to shareholders who have not
                          complied with IRS taxpayer identification regulations. You may avoid
                          this withholding requirement by certifying on your Account Registration
                          Form your proper Social Security or Taxpayer Identification Number and
                          by certifying that you are not subject to backup withholding.
                          The Fund has obtained a Certificate of Authority to do business as a
                          foreign corporation in Pennsylvania and does business and maintains an
                          office in that state. In the opinion of counsel, the shares of the Fund
                          are exempt from Pennsylvania personal property taxes.
                          The tax discussion set forth above is included for general information
                          only. Prospective investors should consult their own tax advisers

THE FUND'S                The Fund's share price or "net asset value" per share is determined by
SHARE PRICE               dividing the total market value of the Fund's investments and other
                          assets, less any liabilities, by the number of outstanding shares of
                          the Fund. Net asset value per share is determined once daily at the
                          close of regular trading on the New York Stock Exchange (generally 4:00
                          p.m. Eastern time) on each day that the Exchange is open for business.
                          Portfolio securities that are listed on a securities exchange are
                          valued at the last quoted sales price on the day the valuation is made.
                          Price information on listed securities is taken from the exchange where
                          the security is primarily traded. Securities which are listed on an
                          exchange and which are not traded on the valuation date are valued at
                          the mean between the bid and ask prices. Unlisted securities for which
                          market quotations are readily available are valued at the latest quoted
                          bid price. Other assets and securities for which no quotations are
                          readily available are valued at fair value as determined in good faith
                          by the Directors. Securities may be valued on the basis of prices

GENERAL                   The Fund is a Maryland corporation. The name of the Fund was changed
INFORMATION               from W.L. Morgan Growth Fund, Inc. to Vanguard/Morgan Growth Fund, Inc.
                          as of April 24, 1990. The Articles of Incorporation permit the
                          Directors to issue 150 million shares of common stock, with a $.10 par
                          value. The Board of Directors has the power to designate one or more
                          classes ("series") of shares of common stock and to classify or
                          reclassify any unissued shares with respect to such series. Currently
                          the Fund is offering one class of shares.
                          The shares of the Fund are fully paid and non-assessable; have no
                          preference as to conversion, exchange, dividends, retirement or other
                          features; and have no pre-emptive rights. Such shares have
                          non-cumulative voting rights, meaning that the holders of more than 50%
                          of the shares voting for the election of Directors can elect 100% of
                          the Directors if they so choose.
                          Annual meetings of shareholders will not be held except as required by
                          the Investment Company Act of 1940 and other applicable law. An annual
                          meeting will be held to vote on the removal of a Director or Directors
                          of the Fund if requested in writing by the holders of not less than 10%
                          of the outstanding shares of the Fund.
                          All securities and cash are held by State Street Bank and Trust
                          Company, Boston, MA. The Vanguard Group, Inc., Valley Forge, PA, serves

                          capital gains, a portion of your investment will be classified as a
                          taxable distribution (regardless of whether you are reinvesting your

                          ASSISTANCE.
SIGNATURE GUARANTEES      For our mutual protection, we may require a signature guarantee on
                          certain written transaction requests. A signature guarantee verifies
                          the authenticity of your signature and may be obtained from banks,
                          brokers and any other guarantor that Vanguard deems acceptable. A
                          SIGNATURE GUARANTEE CANNOT BE PROVIDED BY A NOTARY PUBLIC.
CERTIFICATES              Share certificates will be issued upon request. If a certificate is
                          lost, you may incur an expense to replace it.
BROKER-DEALER             If you purchase shares in Vanguard Funds through a registered
PURCHASES                 broker-dealer or investment adviser, the broker-dealer or adviser may
                          charge a service fee.
CANCELLING TRADES         The Fund will not cancel any trade (e.g., a purchase, exchange or
                          redemption) believed to be authentic, received in writing or by
                          telephone, once the trade has been received.
- -------------------------------------------------------------------------------------------------
WHEN YOUR                 Your trade date is the date on which your account is credited. If your
ACCOUNT WILL              purchase is made by check, Federal Funds wire or exchange, and is
BE CREDITED               received by the close of the New York Stock Exchange (generally 4:00
                          p.m. Eastern time), your trade date is the day of receipt. If your
                          purchase is received after the close of the Exchange, your trade date
                          is the next business day. Your shares are purchased at the net asset
                          value determined on your trade date.
                          In order to prevent lengthy processing delays caused by the clearing of
                          foreign checks, Vanguard will only accept a foreign check which has
                          been drawn in U.S. dollars and has been issued by a foreign bank with a
                          U.S. correspondent bank.
                          Because of the risks associated with common stock investments, the Fund
                          is intended to be a long-term investment vehicle and is not designed to
                          provide investors with a means of speculating on short-term stock
                          market movements. Consequently the Fund reserves the right to reject
                          any specific purchase (and exchange purchase) request. The Fund also
                          reserves the right to suspend the offering of shares for a period of
                          time.

                          minimum account balance requirement. You would then be allowed 60 days
                          to make an additional investment before the account is liquidated.
                          Proceeds would be promptly paid to the shareholder. This minimum does
                          not apply to IRAs, other retirement accounts, and Uniform Gifts to

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

                          - When opening a new account by exchange, you must meet the minimum
                            investment requirement of the new Fund.
                          Neither the Fund nor Vanguard is responsible for the authenticity of
                          exchange instructions received by telephone. Investors bear the full
                          risk of loss arising from unauthorized telephone exchanges. To prohibit
                          telephone exchanges on your account, please notify the Fund in writing.
                          Otherwise, the telephone exchange privilege will be automatically
                          established on your account.
                          Every effort will be made to maintain the exchange privilege. However,
                          the Fund reserves the right to revise or terminate its provisions,
                          limit the amount of or reject any exchange, as deemed necessary, at any
                          time.

EXCHANGE                  The Fund's exchange privilege is not intended to afford shareholders a
PRIVILEGE                 way to speculate on short-term movements in the market. Accordingly, in
LIMITATIONS               order to prevent excessive use of the exchange privilege that may
                          potentially disrupt the management of the Fund and increase transaction
                          costs, the Fund has established a policy of limiting excessive exchange
                          activity.
                          Exchange activity will not be deemed excessive if limited to TWO

                          during any calendar year. These limitations do not apply to exchanges
                          from Vanguard's money market portfolios.

                                 MARCH 11, 1994
 
     On February 25, 1994, Vanguard/Morgan Growth Fund announced a change in the
proportion of the net assets of the Fund managed by each of the Fund's
investment advisers, to be completed by March 31, 1994. The portion of the
Fund's assets managed by Wellington Management Company ("Wellington Management")
will be reduced from 51% to approximately 40% of net assets. The share of net
assets managed by Franklin Portfolio Associates will be increased from 22% to
approximately 33%. The shares managed by the Fund's other two advisers will
remain unchanged: Husic Capital Management (13%) and Vanguard Core Management
(9%). Approximately 5% of the Fund's net assets is held in cash.
 
     In addition, the Fund announced the following portfolio manager change to
be completed prior to March 31, 1994. Robert D. Rands, 51, Senior Vice President
of Wellington Management, will assume responsibility for Wellington Management's
portion of the Fund's net assets. Mr. Rands has been associated with Wellington
Management for 16 years.
 
     The investment objectives and policies of the Fund will remain unchanged.

                                 JUNE 28, 1993
 
     On June 18, 1993, the Board of Directors of Vanguard/Morgan Growth Fund,
Inc. (the "Fund") approved the appointment of Husic Capital Management of San
Francisco, California ("Husic") as an additional investment adviser to manage
approximately 15% of the Fund's assets. The proportion of the net assets of the
Fund managed by each of the Fund's investment advisers (see page 8) may be
changed by the Board of Directors as circumstances warrant.
 
     An Information Statement providing detailed information concerning this new
investment advisory relationship will be mailed to shareholders of the Fund at
least 30 days before the effective date of the new investment advisory
agreement. It is expected that the effective date of the agreement will be on or
about September 15, 1993. Under the terms of the agreement, the Fund will pay
Husic a basic advisory fee at the end of each fiscal quarter, calculated by
applying a quarterly rate, based on the following annual percentage rates, to
the average month-end assets of the Fund managed by Husic for the quarter:
 
<TABLE>
<CAPTION>
    NET ASSETS        ANNUAL RATE
- ------------------    -----------
<S>                   <C>
First $25 million       0.40%
Next $125 million       0.35%
Next $350 million       0.25%
Next $500 million       0.20%
Over $1 billion         0.15%
</TABLE>
 
     Effective with the quarter ending September 30, 1994, the basic fee paid to
Husic, as provided above, may be increased or decreased by as much as 75% by
applying an incentive/penalty fee based on the investment performance of the
assets managed by Husic relative to the return of the Growth Fund Stock Index
(described on page 9).

                                  JUNE 1, 1993
 
     As of May 4, 1993, Roll and Ross Asset Management Corporation ("Roll and
Ross") no longer serves investment advisory services to Vanguard/Morgan Growth
Fund, Inc. (the "Fund"). The assets previously allocated to Roll and Ross
(approximately 15% of the Fund's assets) will be managed on an at-cost basis by
Vanguard's Core Management Department until a replacement investment adviser is
selected in accordance with the Investment Company Act of 1940. The Fund's Board
of Directors may, without the approval of shareholders, provide for the
employment of a new adviser pursuant to the terms of a new advisory agreement.
Any such change will only be made upon not less than 30 days' prior written
notice to shareholders, which shall include detailed information concerning the
new adviser.
