INVESTMENT OBJECTIVES AND POLICIES

Vanguard Money Market Reserves, Inc. is a diversified, open-end investment
management company that consists of two separate Portfolios: Federal and Prime.
The Treasury Money Market Portfolio is part of Vanguard Treasury Fund, which is
a diversified, open-end investment management company as well.

   Each Portfolio seeks to provide current income and to maintain liquidity and
a stable share price of $1.00. Each Portfolio focuses on specific high-quality,
short-term money market instruments, such as securities backed by the full faith
and credit of the U.S. Government, securities issued by U.S. Government
agencies, or obligations issued by corporations and financial institutions.

   IT IS IMPORTANT TO NOTE THAT EACH PORTFOLIO SEEKS TO MAINTAIN, BUT DOES NOT
GUARANTEE, A STABLE NET ASSET VALUE OF $1.00 PER SHARE. IN ADDITION, NONE OF THE
PORTFOLIOS' SHARES IS GUARANTEED OR INSURED BY THE FDIC, THE U.S. GOVERNMENT, OR
ITS AGENCIES.

FEES AND EXPENSES

The Portfolios are offered on a no-load basis, which means that you pay no sales
commissions or 12b-1 marketing fees. You will, however, incur expenses for
investment advisory, management, administrative, and distribution services,
which are included in each Portfolio's expense ratio.

ADDITIONAL INFORMATION ABOUT THE PORTFOLIOS

Statements of Additional Information (dated December 1, 1996) containing more
information about the Portfolios are, by reference, part of this prospectus and
may be obtained without charge by writing to Vanguard or by calling our Investor
Information Department at 1-800-662-7447.

   For investments of $10 million or more, Vanguard Money Market Reserves offers
Prime Portfolio Institutional Shares (available through a separate prospectus).
The Prime Portfolio and the Prime Portfolio Institutional Shares do not have the
same expenses; as a result, the two Portfolios' performance could differ.

WHY READING THIS PROSPECTUS IS IMPORTANT

This prospectus explains the objectives, risks, and policies of the three
Portfolios. To highlight terms and concepts important to mutual fund investors,
we have provided "Plain Talk" explanations along the way. Reading the prospectus
will help you to decide whether one or more of the Portfolios is the right
investment for you. We suggest that you keep it for future reference.

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

                                       Vanguard Treasury Money Market Portfolio



WHO SHOULD INVEST (page 7)
- -  Investors seeking a money market mutual fund as part of a balanced and
   diversified investment program.
- -  Investors uncomfortable with share-price fluctuations.
- -  Investors seeking current income.
- -  Investors needing a temporary holding place for a portion of their assets.

WHO SHOULD NOT INVEST
- -  Investors seeking growth of their investment over time.
- -  Investors looking for a fund that invests in stocks or bonds.

RISKS OF THE PORTFOLIOS (pages 7-10)
Each Portfolio is subject to income risk (the chance that falling short-term
interest rates will cause the Portfolios' income--and thus the Portfolios'
return--to decline). In addition, while the credit quality of all three
Portfolios is expected to be very high, each Portfolio is subject to some degree
of credit risk (the chance that the issuer of a security will be unable to pay
interest and principal in a timely manner). More detailed information about
risk--including risks specific to each Portfolio--is provided beginning on page
8.

DIVIDENDS (page 13)
Dividends are declared daily and paid on the first business day of each month.

INVESTMENT ADVISER (page 14)
Vanguard Fixed Income Group manages each of the three Portfolios.

MINIMUM INITIAL INVESTMENT FOR EACH PORTFOLIO: $3,000; $1,000 for IRAs and
custodial accounts for minors

In evaluating past performance, remember that it is not indicative of future
performance. Performance figures include the reinvestment of any dividends. The
returns shown are net of expenses, but they do not reflect income taxes an
investor would have incurred. An investment in a money market fund is neither
insured nor guaranteed by the U.S. Government, and there is no assurance that
the fund will be able to maintain a stable net asset value of $1.00 per share.

*On 12/1/96, the U.S. Treasury Portfolio (known as the Insured Portfolio prior
to 3/13/89) was reorganized as a separate portfolio of the Vanguard Treasury
Fund and renamed the Treasury Money Market Portfolio.
**Money market portfolios are listed separately from the daily mutual fund
listings.

Portfolio Expenses

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

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

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

   The next table illustrates the operating expenses that you would incur as a
shareholder of each Portfolio. These expenses are deducted from the Portfolio's
income before it is paid to you. Expenses include investment advisory fees as
well as the costs of maintaining accounts, administering the Portfolios,
providing shareholder services, and other activities. The expenses shown in the
table are based upon expenses incurred in the fiscal year ended November 30,
1995 (the expenses for the Treasury Money Market Portfolio are based upon those
of the U.S. Treasury Portfolio for its fiscal year ended November 30, 1995).


PLAIN TALK ABOUT

THE COSTS OF INVESTING

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

FUND EXPENSES

All mutual funds have operating expenses. These expenses, which are deducted
from a fund's gross income, are expressed as a percentage of the net assets of
the fund. For instance, the Prime Portfolio's expense ratio in fiscal year 1995
was 0.32%, or $3.20 per $1,000 of average net assets. The average money market
fund had expenses in 1995 of 0.74%, or $7.40 per $1,000 of average net assets,
according to Lipper Analytical Services, Inc., which reports on the mutual fund
industry.

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

FINANCIAL HIGHLIGHTS

The following financial highlights tables show the results for a share
outstanding for each of the last ten years ended November 30, 1995 and the six
months ended May 31, 1996. The financial highlights for the fiscal years ended
November 30 were audited by Price Waterhouse LLP, independent accountants. The
information for the six-month period ended May 31, 1996, has not been audited by
independent accountants. You should read this information in conjunction with
each Portfolio's financial statements and accompanying notes, which appear in
Vanguard Money Market Reserves' most recent Annual Report (along with the audit
report from Price Waterhouse) and Semi-Annual Report to shareholders. The Annual
Report and Semi-Annual Report are incorporated by reference in the Statement of
Additional Information and in this prospectus, and contains a more complete
discussion of each Portfolio's performance. You may have the Reports sent to you
without charge by writing to Vanguard or by calling our Investor Information

HOW TO READ THE FINANCIAL HIGHLIGHTS TABLE

This explanation uses the Treasury Money Market Portfolio as an example. The
Treasury Money Market Portfolio (then known as the U.S. Treasury Portfolio)
began fiscal 1995 with a net asset value (price) of $1.00 per share. During the
year, the Portfolio earned $.053 per share from investment income (interest and
dividends). All of these earnings were returned to shareholders in the form of 
dividend distributions. The earnings ($.053 per share) less distributions 
($.053 per share) resulted in a share price of $1.00 at the end of the year. 
Assuming that the shareholder had reinvested the distribution in the purchase 
of more shares, total return from the Portfolio was 5.47% for the year.

  As of December 31, 1995, the Portfolio had nearly $2.53 billion in net assets;
an expense ratio of 0.32% ($3.20 per $1,000 of net assets); and net investment
income amounting to 5.33% of its average net assets.

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



A WORD ABOUT RISK

This prospectus describes the risks you will face as an investor in the Treasury
Money Market, Federal, and Prime Portfolios. It is important to keep in mind one
of the main axioms of investing: the higher the risk of losing money, the higher
the potential reward. The reverse, also, is generally true: the lower the risk,
the lower the potential reward. As you consider an investment in one or more of
the Portfolios, you should weigh your desire for income with your need to
protect your investment.

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



THE PORTFOLIOS' OBJECTIVES

Each Portfolio seeks to provide current income while maintaining liquidity and a
stable net asset value of $1.00 per share. These objectives are fundamental,
which means that they cannot be changed unless a majority of Portfolio
shareholders vote to do so.


WHO SHOULD INVEST

Any of the Portfolios may be a suitable investment for you if:

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

- -  You want an investment that does not fluctuate in value.

- -  You want current income.

- -  You characterize your investment temperament as "very conservative."

- -  You want to be able to move your money into stock or bond investments quickly
   and without penalty.

   Each Portfolio is intended to serve most investors' short-term needs.
However, investors who engage in excessive in-and-out trading activity generate
additional costs that are borne by all of the Portfolio's shareholders. To
minimize such costs, which reduce the ultimate returns achieved by you and other
shareholders, the Portfolios have adopted the following policies: 


- -  Each of the Portfolios reserves the right to reject any purchase request--
   including exchanges from other Vanguard Funds--that


                                       7
<PAGE>   12
  it regards as disruptive to the efficient management of the Portfolio.

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



INVESTMENT POLICIES

This section explains how the Portfolios' investment adviser pursues the
objectives of income, liquidity, and stability. It also explains several
important risks--income risk, manager risk, and credit risk--faced by Portfolio
shareholders. Unlike the Portfolios' objectives, the Fund's policies are not
fundamental and can be changed by the Funds' Boards of Directors or Trustees
without shareholder approval. However, before making any important change in its
policies, the Funds will give shareholders 30-days notice, in writing.

MARKET EXPOSURE

Each Portfolio invests in very high-quality money market instruments--also known
as cash reserves--that are considered short term (that is, they mature in 13
months or less).

[FLAG    EACH PORTFOLIO IS SUBJECT TO INCOME RISK, WHICH IS THE POSSIBILITY
GRAPHIC] THAT A PORTFOLIO'S DIVIDENDS (THAT IS, INCOME) WILL DECLINE BECAUSE 
         OF FALLING INTEREST RATES. BECAUSE THE PORTFOLIOS' INCOME IS BASED ON 
         SHORT-TERM INTEREST RATES--WHICH CAN FLUCTUATE SIGNIFICANTLY OVER SHORT
         PERIODS--INCOME RISK IS EXPECTED TO BE HIGH FOR ALL THREE PORTFOLIOS.

   To illustrate how the yields of short-term securities can fluctuate as
interest rates rise and fall, the following chart shows month-end yields for
short-term securities (as represented by 90-day Treasury bills) and long-term
securities (as represented by 30-year U.S. Treasury bonds) over the past five
years. Note in this illustration how short-term yields tend to fluctuate more
than longer-term yields.

These yields reflect past performance and should not be regarded as an
indication of future returns from either Treasury bills or bonds as a whole or
any of the Portfolios in particular.


PLAIN TALK ABOUT

CASH RESERVES

Cash reserves are any investment that can be easily converted into cash with
little or no cost or penalty. A money market mutual fund, a checking account or
certificate of deposit (CD) at a bank, and Treasury bills issued by the U.S.
Government are examples of cash reserves. Keep in mind, however, that each type
varies in its credit quality and its ability to provide a competitive yield.

SECURITY SELECTION

Vanguard Fixed Income Group, adviser to the Portfolios, selects high-quality
money market instruments. Each Portfolio focuses on securities of a particular
class of issuer (for example, the U.S. Government, U.S. Government agencies,
financial institutions).

[FLAG    EACH PORTFOLIO IS SUBJECT TO MANAGER RISK, WHICH IS THE POSSIBILITY
GRAPHIC] THAT VANGUARD FIXED INCOME GROUP MAY DO A POOR JOB OF SELECTING
         SECURITIES.

         The Treasury Money Market Portfolio invests solely in securities whose
interest and principal payments are backed by the full faith and credit of the
U.S. Government. At least 65% of the Portfolio's assets will always be invested
in U.S. Treasury securities. The remainder of the Portfolio's assets may include
securities issued by the U.S. Treasury and other government agencies, such as
the Government National Mortgage Association (GNMA), the Small Business
Administration, and the Federal Financing Bank. 

         The Federal Portfolio invests in securities whose interest and
principal payments are backed by the full faith and credit of the U.S.
Government or by an agency of the Government (these agency securities are not
backed by the full faith and credit of the U.S. Government). These agencies
include, among others, the Federal Home Loan Bank, the Federal National Mortgage
Association (FNMA), the Tennessee Valley Authority, and the Federal Land Bank.

         The Prime Portfolio invests in certificates of deposit, bankers
acceptances, commercial paper, and other money market securities rated Prime-1
by Moody's Investors Services, Inc., or A-1 by Standard & Poor's Corporation.
Securities that are unrated must be issued by a corporation with a debt rating
of Aa3 or better by Moody's or AA- or better by Standard & Poor's. The Prime
Portfolio also invests in short-term corporate, state, and municipal obligations
rated Aa3 or better by Moody's or AA- or better by Standard & Poor's; and
securities that are considered suitable for the Federal Portfolio (see the
previous paragraph). 

         The Prime Portfolio may also invest in Eurodollar and Yankee
obligations, which are certificates of deposit issued in U.S. dollars by foreign
banks and foreign branches of U.S. banks. Eurodollar and Yankee obligations have
the same risks, such as income risk and credit risk, as U.S. money market
instruments. Other risks of Eurodollar and Yankee obligations include the
possibility that a foreign government will not let U.S. dollar-denominated
assets leave the country; and the possibility that adverse political or economic
developments will affect investments in a foreign country. Before the
Portfolio's adviser selects a Eurodollar or Yankee obligation, however, any
foreign issuer undergoes the same credit-quality analysis and tests of financial
strength as the issuers of domestic securities.

                            Money Market Instruments

The term "money market instruments" refers to a variety of short-term
investments, usually with a maturity of 13 months or less. Some common types are
Treasury bills and notes, which are securities issued by the U.S. Government;
commercial paper, which is a promissory note issued by a large company or
financial firm; bankers acceptances, which are credit instruments guaranteed by
a bank; and negotiable certificates of deposit, which are issued by banks in
large denominations.

                                PLAIN TALK ABOUT

                           Credit Quality and Ratings

A money market instrument's credit quality depends upon the issuer's ability to
pay interest on the security and, ultimately, to repay the debt. The lower the
rating by one of the independent bond-rating agencies (for example, Moody's or
Standard & Poor's), the greater the chance (in the rating agency's opinion) the
security's issuer will default, or fail to meet its payment obligations. Direct
U.S. Treasury obligations (that is, securities backed by the U.S. Government)
carry the highest credit ratings. All things being equal, money market
instruments with greater credit risk offer higher yields.

                              Repurchase Agreements

A means of investing money for a short period, repurchase agreements are
contracts in which a U.S. commercial bank or securities dealer sells government
securities and agrees to repurchase the securities on a specific date (normally
the next business day) and at a specific price.

                                PLAIN TALK ABOUT

                                   Derivatives

A derivative is a financial contract whose value, or interest rate, is based on
(or "derived" from) a traditional security (such as a stock or bond), money
market benchmark (such as U.S. Treasury bill rates or Federal Funds Effective
Rate), an asset (such as a commodity like gold), or a market index (such as the
S&P 500 Index).

[FLAG    EACH PORTFOLIO IS SUBJECT, TO A LIMITED EXTENT, TO CREDIT RISK, WHICH
GRAPHIC] IS THE POSSIBILITY THAT THE ISSUER OF A SECURITY WILL BE UNABLE TO
         REPAY INTEREST AND PRINCIPAL IN A TIMELY MANNER.

         The three Portfolios differ mainly in terms of credit risk. In absolute
terms, each Portfolio's credit quality is very high.

         In relative terms, the Treasury Money Market Portfolio, which invests
in securities backed by the full faith and credit of the U.S. Government, offers
the lowest credit risk--and generally the lowest yield--of the three Portfolios.

         Not all of the securities included in the Federal Portfolio are backed
by the full faith and credit of the U.S. Government, and so the Portfolio's
potential credit risk and yield are somewhat higher than the Treasury Money
Market Portfolio.

         While the credit quality of its securities is very high, the Prime
Portfolio invests in money market securities of private financial and
nonfinancial corporations; therefore, it offers the highest credit risk and
generally the highest yield of the three Portfolios.

         Bear in mind that, while each Portfolio invests in high-quality money
market instruments, the three Portfolios are not insured or guaranteed by the
FDIC or any other agency of the U.S. Government.

[FLAG    THE PRIME AND FEDERAL PORTFOLIOS RESERVE THE RIGHT TO INVEST IN
GRAPHIC] REPURCHASE AGREEMENTS, WHICH ARE SUBJECT TO SPECIFIC RISKS.

         Repurchase agreements carry several risks. For instance, if the seller
is unable to repurchase the securities as promised, the Portfolio may experience
a loss when trying to sell the securities itself. Or, if the seller becomes
insolvent, a bankruptcy court may determine that the securities do not belong to
the Portfolio and order that the securities be sold to pay off the seller's
debts. The Portfolio's adviser believes that these risks can be controlled
through careful security selection and monitoring.

[FLAG    THE PORTFOLIOS RESERVE THE RIGHT TO INVEST, TO A LIMITED EXTENT, IN
GRAPHIC] FLOATING-RATE SECURITIES, WHICH ARE TRADITIONAL TYPES OF DERIVATIVES.

         A floating-rate security's interest rate, as the name implies, is not
set; instead, it fluctuates periodically. Generally, the security's yield is
based on a U.S. dollar-based interest-rate benchmark such as the Federal Funds
Rate, the 90-day Treasury bill rate, or the London Interbank Offered Rate
(LIBOR). These securities reset their yields on a periodic basis (for example,
daily, weekly, or quarterly) and are closely correlated to changes in money
market interest rates.

         The Portfolios will not use derivatives for speculative purposes or as
leveraged investments that magnify the risks of an investment.

<PAGE>   15
PORTFOLIO TURNOVER

Because of the short-term nature of money market instruments, the turnover rate
for each Portfolio is expected to be high. This high turnover rate should not
increase Portfolio costs, however, since brokerage commissions are not usually
charged for the purchase or sale of money market instruments.

Investment Limitations

To reduce risk and maintain diversification, the Portfolios have adopted limits
on some of their investment policies. Specifically, each Portfolio will not:

- -        Invest more than 5% of its assets in the securities of any one issuer,
         excluding the U.S. Government.

- -        Buy more than 10% of any class of securities of any issuer.

- -        Invest more than 25% of its assets in any one industry, excluding
         obligations of the U.S. Government, certificates of deposit, and U.S.
         bankers acceptances.

- -        Borrow money, except for emergency purposes. Amounts borrowed will not
         exceed 15% of the Portfolio's net assets.

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

Investment Performance

The Portfolios invest in short-term securities; therefore, their performance is
closely correlated to short-term interest rates. Historically, short-term
interest rates' up-and-down fluctuations have been influenced primarily by
Federal Reserve policy and by market supply and demand.

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

         The results shown above represent the Portfolios' "average annual total

Share Price

Each Portfolio's share price, called its net asset value, is expected to remain
at a constant $1.00. Although the stable share price is not guaranteed, the
Portfolios are managed and securities are purchased to maintain that price.

Dividends and Taxes

Each Portfolio's dividends accrue daily. On the first business day of every
month, the Portfolios distribute to shareholders virtually all of their income
from interest as dividend distributions. As a shareholder, you are entitled to
your share of a Portfolio's income from interest and dividends. You can receive
income distributions in cash, or you may have them automatically reinvested in
more shares of the Portfolio. In either case, distributions that are earned in
December--even if paid to you in January--are taxed as if they had been paid in
December. Vanguard will process your dividend distributions and send you a
statement each year showing the tax status of all of your distributions.

- -        The dividends that you receive are taxable to you as ordinary dividend
         income whether received in cash or reinvested in additional shares.

- -        Distributions of dividends may be subject to state and local taxes as
         well. However, depending on your state's tax rules, the portion of a
         Portfolio's dividends that come from U.S. Treasury securities and other
         "direct" U.S. Treasury obligations may be exempt from state and local
         taxes. The Portfolios will notify you each year how much, if any, of
         your distribution may qualify for this exemption.

         The tax information in this prospectus is provided as general
information. You should consult your own tax adviser about the tax consequences
of an investment in one or more of the Portfolios.

The Funds and Vanguard

Vanguard Treasury Fund and Vanguard Money Market Reserves are members of The
Vanguard Group, a family of more than 30 investment companies with more than 90
distinct investment portfolios and total net assets of more than $200 billion.
All of the Vanguard Funds share in the expenses associated with business
operations, such as personnel, office space, equipment, and advertising.

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

         A list of each Fund's Directors (or Trustees) and Officers, and their
present positions and principal occupations during the past five years, can be
found in each Fund's Statement of Additional Information.

                      Vanguard's Unique Corporate Structure

The Vanguard Group, Inc. is the only MUTUAL mutual fund company. It is owned
jointly by the Funds it oversees and by the shareholders in those Funds. Other
mutual funds are operated by for-profit management companies that may be owned
by one person, by a group of individuals, or by investors who bought the
management company's publicly traded stock. Because of its structure, Vanguard
operates its Funds at cost. Instead of distributing profits from operations to a
separate management company, Vanguard returns profits to Fund shareholders in
the form of lower operating expenses.

Investment Adviser

Vanguard Fixed Income Group, P.O. Box 2600, Valley Forge, PA 19482, provides
advisory services on an at-cost basis to the Treasury Money Market, Federal, and
Prime Portfolios. For the year ended November 30, 1995, the three Portfolios
paid a total of $2,788,000 in investment advisory expenses ($297,000 for the
U.S. Treasury Portfolio, $310,000 for the Federal Portfolio, and $2,181,000 for
the Prime Portfolio). For the six months ended May 31, 1996, the three
Portfolios paid a total of $1,461,000 ($152,000 for the U.S. Treasury Portfolio,
$155,000 for the Federal Portfolio, and $1,154,000 for the Prime Portfolio).

         The Group places all orders for purchases and sales for Portfolio
securities, and is directed to get the best available price and most favorable
execution with respect to all transactions.

General Information

Vanguard Money Market Reserves Inc. is organized as a corporation under the laws
of the State of Maryland. Until December 1, 1996, the Treasury Money Market
Portfolio was a Portfolio of Vanguard Money Market Reserves, known as the U.S.
Treasury Portfolio. On that date, the Treasury Money Market Portfolio was
reorganized--through a transfer of assets into a Portfolio of Vanguard Treasury
Fund, a Delaware business trust.

         Shareholders of the Funds have rights and privileges similar to those
enjoyed by other corporate shareholders. For example, shareholders will not be
responsible for any liabilities of the trust or corporation. If any matters are
to be voted on by shareholders (such as a change in a fundamental investment
objective or the election of directors or trustees), each share outstanding at
that point would be entitled to one vote. Although the Funds do not usually hold
annual meetings, shareholders may request one under certain circumstances, which
are described in each Fund's Statement of Additional Information.

Distribution Options

You can receive your dividend distributions in one of two ways:

REINVESTMENT                     Dividends are reinvested in additional shares
                                 of the Portfolio.

DIVIDENDS                        in Cash Dividends are paid by check and mailed
                                 to your account's address of record.

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

Buying Shares

You buy your Portfolio shares at a net asset value of $1.00 per share. Before it
can begin earning dividends, your investment must be converted to Federal funds,
which usually takes one business day. (Federal funds are Federal Reserve
deposits that banks and other financial institutions "borrow" from one another
to meet short-term cash needs; portfolio advisers must use Federal funds to pay
for the securities they buy.) You begin earning dividends the calendar day after
the Portfolio receives the Federal funds.

         The Portfolios are offered on a no-load basis, meaning that you do not
pay sales commissions or 12b-1 marketing fees.

Buying Shares (continued)

If Vanguard receives your check by 4:00 p.m. Eastern time (the close of trading
on the New York Stock Exchange), your investment is converted to Federal funds
the following business day, and you begin earning dividends the next calendar
day. (For instance, if we received your check before 4:00 p.m. on a Thursday,
your account would be credited Friday, and you would begin earning dividends
Saturday.)

         If the check arrives after 4:00 p.m. Eastern time, your account is
credited after two business days, and you begin earning dividends the calendar
day after that. (If we received your check after 4:00 p.m. on a Thursday, your
account would be credited Monday, and you would begin earning dividends
Tuesday.)

IMPORTANT NOTE: To prevent check fraud, Vanguard will not accept checks made
payable to third parties.

AUTOMATICALLY                                       Vanguard offers a variety of ways 
                                                    that you can add to your account 
                                                    automatically. See "Services and

</TABLE>

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

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

Redeeming Shares

IMPORTANT TAX NOTE: Any sale or exchange of shares in a non-retirement account
could result in a taxable gain or a loss. However, because the Portfolios seek
to maintain a stable net asset value of $1.00 per share, you will not incur a
taxable gain or loss when you sell or exchange shares of these Portfolios.

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

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

         - Portfolio name.

         - 10-digit account number.

         - Name and address exactly as registered on that account.

         - Social Security or Employer Identification number as registered on
that account.

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

         If we follow reasonable security procedures, neither the Portfolio nor
Vanguard will be responsible for the authenticity of transaction instructions
received by telephone. We believe that these procedures are reasonable and that,
if we follow them, you bear the risk of any losses resulting from unauthorized
or fraudulent telephone transactions on your account. However, if we do not
follow these or other reasonable procedures, Vanguard may be liable for any
losses resulting from unauthorized or fraudulent transactions. 

HOW TO SELL SHARES 

You may withdraw any part of your account, at any time, by selling shares.

         One way to sell shares is the checkwriting option (established when you
set up your account or by calling Client Services). Your personalized Vanguard
checks work in much the same way as bank checks, except that Vanguard checks are
considered drafts and cannot be cashed immediately like a bank check.

Redeeming Shares (continued)

         When you sell shares by telephone or mail, sale proceeds are normally
mailed within two business days after Vanguard receives your request in good
order. Good order means that the request includes:

         - Portfolio name and account number.

         - Amount of the transaction (in dollars).

         - Signatures of all owners exactly as registered on the account.

         - Signature guarantees (if required).

         - Any supporting legal documentation that may be required.

         - Any certificates you are holding for the account.

         Sales or exchange requests received after the close of trading on the
New York Stock Exchange (generally 4:00 p.m. Eastern time) are processed the
next business day.

         The Portfolios reserve the right to close any non-retirement or
UGMA/UTMA account whose balance falls below the minimum initial investment. The
Portfolios will deduct a $10 annual fee if your non-retirement account balance
falls below $2,500 or if your UGMA/UTMA account balance falls below $500. The
fee is waived if your total Vanguard account assets are $50,000 or more.

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

HOW TO EXCHANGE SHARES

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

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

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

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

                         A NOTE ON UNUSUAL CIRCUMSTANCES

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

                             INVESTMENT LIMITATIONS
 
     The following policies supplement the investment limitations set forth in
the Prospectus. It is a fundamental policy of the Portfolio not to engage in any
of the following activities or business practices. These restrictions may not be
changed with respect to the Portfolio without the approval of a majority of the
outstanding shares (as defined in the Investment Company Act of 1940) of the
Portfolio. The Portfolio may not:
 
      1) purchase securities other than the securities in which the Portfolio is
         authorized to invest as set forth in the Prospectus;
 
      2) borrow money in excess of 15% of the total assets of the Portfolio
         taken at market value and then only from banks as a temporary measure
         for extraordinary or emergency purposes; provided, the Portfolio may
         borrow from any existing and future investment company member of The
         Vanguard Group of Investment Companies, or its predecessors, through
         its interfund lending facility; the Portfolio will not borrow to
         increase income (leveraging) but only to facilitate redemption requests
         which might otherwise require untimely dispositions of portfolio
         securities; the Portfolio will repay all borrowings before making
         additional investments and interest paid on such borrowings will reduce
         net income;
 
      3) make loans to other persons (except by the purchase of obligations in
         which the Portfolio is authorized to invest); provided, the Portfolio
         may make loans to any existing and future investment company member of
         The Vanguard Group or its predecessors, through its interfund lending
         facility; provided further, however, that the Portfolio will not enter
         into repurchase agreements if, as a result thereof, more than 10% of
         the net assets of the Portfolio (taken at current value) would be
         subject to repurchase agreements maturing in more than seven days;
 
      4) purchase the securities of any issuer (other than obligations issued or
         guaranteed as to principal and interest by the Government of the United
         States, its agencies or instrumentalities) if, as a result, (a) more
         than 5% of the Portfolio's total assets (taken at current value) would
         be invested in the
 
                                        1
<PAGE>   30
 
         securities of such issuer, or (b) the Portfolio would hold more than
         10% of any class of securities of such issuer (for this purpose, all
         debt obligations of an issuer maturing in less than one year are
         treated as a single class of securities);
 
      5) write, or invest in, put, call, straddle or spread options or invest in
         interests in oil, gas or other mineral exploration or development
         programs;
 
      6) purchase securities on margin or sell any securities short;
 
      7) purchase any securities which could cause more than 25% of the value of
         the Portfolio's total net assets at the time of such purchase to be
         invested in the securities of one or more issuers conducting their
         principal business activities in the same industry, provided that there
         is no limitation with respect to investments in United States Treasury
         Bills, other obligations issued or guaranteed by the Federal
         Government, its agencies and instrumentalities or certificates of
         deposit or bankers' acceptances of domestic institutions;
 
      8) mortgage, pledge or hypothecate its assets except in an amount up to
         15% (10% as long as the Fund's shares are registered for sale in
         certain states) of the value of the Portfolio's total assets but only
         to secure borrowings for temporary or emergency purposes;
 
      9) engage in the business of underwriting securities issued by other
         persons, except to the extent that the Portfolio may technically be
         deemed to be an underwriter under the Securities Act of 1933, as
         amended, in disposing of investment securities;
 
     10) purchase or otherwise acquire any security if, as a result, more than
         10% of its net assets (including any investment in The Vanguard Group,
         Inc.) would be invested in securities that are illiquid;
 
     11) purchase or sell real estate, real estate investment trust securities,
         commodities, or commodity contracts;
 
     12) invest in companies for the purpose of exercising control;
 
     13) invest in securities of other investment companies, except as may be
         acquired as a part of a merger, consolidation or acquisition of assets
         approved by the Portfolio's shareholders or otherwise to the extent
         permitted by Section 12 of the Investment Company Act of 1940. The
         Portfolio will invest only in investment companies which have
         investment objectives and investment policies consistent with those of
         the Portfolio;
 
     14) issue senior securities.
 
     Notwithstanding these limitations, the Portfolio may own all or any portion
of the securities of, or make loans to, or contribute to the costs or other
financial requirements of, any company which will be: (1) wholly owned by the
Fund and one or more other investment companies, and is (2) primarily engaged in
the business of providing, at-cost, management, administrative, distribution or
related services to the Fund and other investment companies. See "Management of
the Fund."
 
     As an operational policy of the Portfolio, the Portfolio will not in the
aggregate, enter into repurchase agreements maturing in more than seven days,
purchase restricted securities or invest in any other illiquid securities if, as
a result thereof, more than 10% of the net assets of the Portfolio would be
invested in such assets.
 
     Although not fundamental policies subject to shareholder vote, as long as
the Fund's shares are registered for sale in certain states, the Portfolio may
not purchase or retain securities of an issuer if an officer or director of such
issuer is an officer or Trustee of the Fund or its investment adviser and one or
more of such officers or directors (trustees) of the Fund or its investment
adviser owns beneficially more than 1/2% of the shares of securities of such
issuer and all such directors and officers owning more than 1/2% of such shares
or securities together own more than 5% of such shares or securities.

     Total return is computed by finding the average compounded rates of return
over the periods set forth above that would equate an initial amount invested at
the beginning of the periods to the ending redeemable value of the investment.
 
                              CALCULATION OF YIELD
 
     The current yield of the Portfolio is calculated daily on a base period
return of a hypothetical account having a beginning balance of one share for a
particular period of time (generally 7 days). The return is determined by
dividing the net change (exclusive of any capital changes) in such account by
its average net asset value for the period, and then multiplying it by 365/7 to
get the annualized current yield. The calculation of net change reflects the
value of additional shares purchased with the dividends by the Portfolio,
including dividends on both the original share and on such additional shares. An
effective yield, which reflects the effects of compounding and represents an
annualization of the current yield with all dividends reinvested, may also be
calculated for the Portfolio by adding 1 to the net change, raising the sum to
the 365/7 power, and subtracting 1 from the result.
 
     Set forth below is an example, for purposes of illustration only, of the
current and effective yield calculations for the Portfolio for the 7-day base
period ended May 31, 1996.

*Exclusive of any capital changes.
 
     The net asset value of a share of the Portfolio is $1.00 and it is not
expected to fluctuate. However, the yield of the Portfolio will fluctuate. The
annualization of a week's dividend is not a representation by the Portfolio as
to what an investment in the Portfolio will actually yield in the future. Actual
yields will depend on such variables as investment quality, average maturity,
the type of instruments the Portfolio invests in, changes in interest rates on
instruments, changes in the expenses of the Fund and other factors. Yields are
one basis investors may use to analyze the Portfolio of the Fund, and other
investment vehicles; however, yields of other investment vehicles may not be
comparable because of the factors set forth in the preceding sentence,
differences in the time periods compared, and differences in the methods used in
valuing portfolio instruments, computing net asset values and calculating
yields.

                               PURCHASE OF SHARES
 
     The Fund reserves the right in its sole discretion (i) to suspend the
offerings of its shares, (ii) to reject purchase orders when in the judgment of
management such rejection is in the best interest of the Fund, and (iii) to
reduce or waive the minimum investment for or any other restrictions on initial
and subsequent investments for certain fiduciary accounts or under circumstances
where certain economies can be achieved in sales of the Fund's shares.
 
                              REDEMPTION OF SHARES
 
     The Fund may suspend redemption privileges for the Portfolio or postpone
the date of payment (i) during any period that the New York Stock Exchange is
closed, or trading on the Exchange is restricted as determined by the Securities
and Exchange Commission (the "Commission"), (ii) during any period when an
emergency exists as defined by the rules of the Commission as a result of which
it is not reasonably practicable for the Portfolio to dispose of securities
owned by it, or fairly to determine the value of its assets, and (iii) for such
other periods as the Commission may permit.
 
     The Fund will make an election with the Commission to pay in cash all
redemptions requested by any shareholder of record limited in amount during any
90-day period to the lesser of $250,000 or l% of the net assets of the Fund at
the beginning of such period. Such commitment is irrevocable without the prior
approval of the Commission. Redemptions in excess of the above limits may be
paid in whole or in part, in investment readily marketable securities or in
cash, as the Trustees may deem advisable; however, payment will be made wholly
in cash unless the Trustees believe that economic or market conditions exist
which would make such a practice detrimental to the best interests of the Fund.
If redemptions are paid in investment securities, such securities will be valued
as set forth in the Prospectus under "The Share Price of the Portfolio" and a
redeeming shareholder would normally incur brokerage expenses if he converted
these securities to cash.
 
     No charge is made by the Fund for redemptions; except for wire withdrawals
in amounts less than $5,000 which will be subject to a maximum charge of $5.00
which will be deducted from the principal in your account. Any redemption may be
more or less than the shareholder's cost depending on the market value of the
securities held by each Portfolio.
 
                              SHAREHOLDER SERVICES
 
     EXCHANGE PRIVILEGE  The Portfolio's shares may be exchanged without cost
for shares of any open-end Fund currently offering its shares to new investors
in The Vanguard Group ("Vanguard"). A shareholder of any other open-end Fund in
Vanguard may likewise exchange his shares for shares of the Portfolio. Exchange
requests may be made either by mail, telephone or telegraph.
 
     Telephone and telegraph exchanges (referred to as "expedited exchanges")
will be accepted only if the registration of the two accounts is identical.
Requests for expedited exchanges received prior to the close of the New York
Stock Exchange (generally 4:00 P.M. Eastern time) will be processed at the next
determined net asset value after such request is received. Requests received
after the close of the New York Stock Exchange (generally 4:00 P.M. Eastern
time), will be processed on the next business day. NO EXPEDITED EXCHANGES WILL
BE ACCEPTED INTO, OR FROM, VANGUARD BALANCED INDEX FUND, VANGUARD INDEX TRUST,
VANGUARD QUANTITATIVE PORTFOLIOS AND VANGUARD INTERNATIONAL EQUITY INDEX FUND.
Neither the Fund nor Vanguard will be responsible for the authenticity of
exchange instructions received by telephone or telegraph. Expedited exchanges
may also be subject to limitations as to amounts and frequency, and to other
restrictions established by the Board of Trustees to assure that such exchanges
do not disadvantage the Fund and its shareholders. Shareholders may obtain the
terms of these limitations, which may be revised at any time, from Vanguard.
 
     Any such exchange will be based on the respective net asset values of the
shares involved. There are no sales commissions or charges of any kind. Before
making an exchange, a shareholder should consider the investment objectives and
policies of the Portfolio or Fund to be purchased, and other relevant
information (including the minimum initial investment), which can be found in
the prospectus relating to that particular Portfolio or Fund. A prospectus for
any of the Vanguard Funds or Portfolios may be obtained from Vanguard.

<PAGE>   33
 
     For Federal income tax purposes an exchange between Funds is a taxable
event and, accordingly, a capital gain or loss may be realized. In a revenue
ruling relating to circumstances similar to the Fund's, an exchange between
series of a Fund was also deemed to be a taxable event. It is likely, therefore,
that a capital gain or loss would be realized on an exchange between Portfolios;
you may want to consult your tax adviser for further information in this regard.
The exchange privilege may be modified or terminated at any time, and the
Portfolio or Vanguard Funds may limit or discontinue the offering of its shares
without notice to shareholders.
 
     TRANSFER OF SHARES  Fund shares may be transferred to another person by
sending appropriate written instructions to Vanguard. The account must be
clearly identified and include the number of shares to be transferred and the
signatures of all registered owners. The signature on the letter of instructions
or any stock power must be guaranteed. As in the case of withdrawals, the
written request must be received in "Good Order" before any transfer can be
made.
 
     INFORMATION FOR SHAREHOLDERS  Following any purchase or redemption, a
shareholder will receive a statement which reflects all activity during the
current calendar year. Each shareholder will also receive a quarterly statement,
which includes a valuation as of the day the statement is prepared.
 
     Shareholders will receive semi-annual financial statements audited at least
annually by independent accountants whose selection is ratified by shareholders.

*Officers of the Fund are "interested persons" as defined in the Investment
 Company Act of 1940.
 
THE VANGUARD GROUP
 
     The Fund is a member of The Vanguard Group of Investment Companies. Through
their jointly-owned subsidiary, The Vanguard Group, Inc. ("Vanguard"), the Fund
and the other Funds in the Group obtain at cost virtually all of their corporate
management, administrative and distribution services. Vanguard also provides
investment advisory services on an at-cost basis to certain of the Vanguard
Funds.
 
     Vanguard employs a supporting staff of management and administrative
personnel needed to provide the requisite services to the Funds and also
furnishes the Funds with necessary office space, furnishings and equipment. Each
Fund pays its share of Vanguard's total expenses which are allocated among the
Funds under methods approved by the Board of Directors (Trustees) of each Fund.
In addition, each Fund bears its own direct expenses such as legal, auditing and
custodian fees.
 
     The Fund's Officers are also Officers and employees of Vanguard. No Officer
or employee owns, or is permitted to own, any securities of any external adviser
for the Funds.

     Vanguard adheres to a Code of Ethics established pursuant to Rule 17j-I
under the Investment Company Act of 1940. The Code is designed to prevent
unlawful practices in connection with the purchase or sale of securities by
persons associated with Vanguard. Under Vanguard's Code of Ethics certain
officers and employees of Vanguard who are considered access persons are
permitted to engage in personal securities transactions. However, such
transactions are subject to procedures and guidelines substantially similar to
those recommended by the mutual fund industry and approved by the U.S.
Securities and Exchange Commission.
 
     Vanguard was established and operates under a Funds' Service Agreement
which was approved by the shareholders of each of the Funds. The amounts of
which each of the Funds has invested are adjusted from time to time in order to
maintain the proportionate relationship between each Fund's relative net assets
and its contribution to Vanguard's capital. At November 30, 1995, the Portfolio
had contributed capital of $-- to Vanguard, representing --% of Vanguard's
capitalization. The Funds' Service Agreement provides as follows: (a) each
Vanguard Fund may invest up to 0.40% of its current assets in Vanguard and (b)
there is no other limitation on the amount that each Vanguard Fund may
contribute to Vanguard's Capitalization.
 
     MANAGEMENT  Corporate management and administrative services include: (1)
executive staff; (2) accounting and financial; (3) legal and regulatory; (4)
shareholder account maintenance; (5) monitoring and control of custodian
relationships; (6) shareholder reporting; and (7) review and evaluation of
advisory and other services provided to the Funds by third parties. During the
fiscal year ended November 30, 1995 and the six months ended May 31, 1996, the
Portfolio's share of Vanguard's actual net costs of operation relating to
management
and administrative services (including transfer agency) totaled approximately
$3,192,000 and $2,080,000, respectively.
 
     DISTRIBUTION  Vanguard provides all distribution and marketing activities
for the Funds in the Group. Vanguard Marketing Corporation, a wholly-owned
subsidiary of Vanguard, acts as Sales Agent for the shares of the Funds, in
connection with any sales made directly to investors in the states of Florida,
Missouri, New York, Ohio, Texas and such other states as it may be required.
 
     The principal distribution expenses are for advertising, promotional
materials and marketing personnel. Distribution services may also include
organizing and offering to the public, from time to time, one or more new
investment companies which will become members of the Group. The Directors and
Officers of Vanguard determine the amount to be spent annually on distribution
activities, the manner and amount to be spent on each Fund, and whether to
organize new investment companies.
 
     One half of the distribution expenses of a marketing and promotional nature
is allocated among the Funds based upon relative net assets. The remaining one
half of those expenses is allocated among the Funds based upon each Fund's sales
for the preceding 24 months relative to the total sales of the Funds as a Group,
provided, however, that no Fund's aggregate quarterly rate of contribution for
distribution expenses of a marketing and promotional nature shall exceed 125% of
average distribution expense rate for the Group, and that no Fund shall incur
annual distribution expenses in excess of 20/100 of 1% of its average month-end
net assets. During the fiscal year ended November 30, 1995 and the six months
ended May 31, 1996, the Portfolio paid approximately $627,000 and $414,000,
respectively of the Group's distribution and marketing expenses or .03 of 1% and
- -- of 1%, respectively of the Portfolio's average month-end net assets.
 
     INVESTMENT ADVISORY SERVICES  Vanguard also provides the Fund, Vanguard
Money Market Reserves, Vanguard Municipal Bond Fund, Vanguard Bond Index Fund,
several Portfolios of Vanguard Fixed Income Securities Fund, Vanguard Admiral
Funds, Vanguard California Tax-Free Fund, Vanguard Pennsylvania Tax-Free Fund,
Vanguard Ohio Tax-Free Fund, Vanguard New York Insured Tax-Free Fund, Vanguard
New Jersey Tax-Free Fund, Vanguard Florida Insured Tax-Free Fund, Vanguard Index
Trust, Vanguard Balanced Index Fund, Vanguard Institutional Index Fund, Vanguard
Tax-Managed Fund, several Portfolios of Vanguard Variable Insurance Fund,
Vanguard International Equity Index Fund, Aggressive Growth Portfolio of
Vanguard Horizon Fund, a portion of Vanguard/Windsor II, a portion of
Vanguard/Morgan Growth Fund as well as several indexed separate accounts with
investment advisory services. These services are provided on an at-cost basis
from a money management staff employed directly by Vanguard. The compensation
and other expenses of this staff are paid by the Funds utilizing these services.
During the years ended November 30, 1993, 1994, 1995 and the six months ended
 
                                        8
<PAGE>   37
 
May 31, 1996, the Portfolio paid approximately $196,000, $212,000, $297,000 and
$152,000, respectively, of Vanguard's expenses relating to investment advisory
services.
 
     REMUNERATION OF TRUSTEES  The Fund pays each Director (Trustee), who is not
also an Officer, an annual fee plus travel and other expenses incurred in
attending Board meetings. The Fund's Officers and employees are paid by Vanguard
which, in turn, is reimbursed by the Fund and each other Fund in the Group, for
its proportionate share of Officers' and employees' salaries and retirement
benefits.
 
     Under its retirement plan, Vanguard contributes annually an amount equal to
10% of each eligible Officer's annual compensation plus 5.7% of that part of an
eligible Officer's compensation during the year, if any, that exceeds the Social
Security Taxable Wage Base then in effect. Under the Thrift Plan, all eligible
Officers are permitted to make pre-tax basic contributions in a maximum amount
equal to 4% of total compensation which are matched by Vanguard on a 100% basis.
 
     DIRECTORS' RETIREMENT FEES  A Retirement Plan for Directors has been
implemented to provide a fee to retired Directors equal to $1,000 per year of
service on the Board, up to 15 years of service. This fee will remain in place
subsequent to the Director's retirement for a period of 10 years or until a
retired Director's death.
 
                    DESCRIPTION OF SHARES AND VOTING RIGHTS
 
     The Declaration of Trust permits the Trustees to issue an unlimited number
of shares of beneficial interest with a par value of $.001. The Board of
Trustees has the power to designate one or more classes ("Portfolios") of shares
of beneficial interest. Currently the Fund is offering shares of one Portfolio.
 
     The shares of the Portfolio are fully paid and nonassessable, and have no
preference as to conversion, exchange, dividends, retirement or other features.
The shares of the Portfolio have no pre-emptive rights. The shares of the
Portfolio have non-cumulative voting rights, which means that the holders of
more than 50% of the shares voting for the election of Trustees can elect 100%
of the Trustees if they choose to do so. A shareholder is entitled to one vote
for each full share held (and a fractional vote for each fractional share held),
then standing in his name on the books of the Fund. On any matter submitted to a
vote of shareholders, all shares of the Fund then issued and outstanding and
entitled to vote, irrespective of the Portfolio or class, shall be voted in the
aggregate and not by Portfolio or class: except (i) when required by the
Investment Company Act of 1940, shares shall be voted by individual Portfolio or
class; and (ii) when the matter does not affect any interest of a particular
Portfolio or class, then only shareholders of the affected class or classes
shall be entitled to vote thereon.

               APPENDIX -- DESCRIPTION OF SECURITIES AND RATINGS
 
DESCRIPTION OF U.S. GOVERNMENT SECURITIES
 
     As used in this prospectus, the term "U.S. Government Securities" refers to
a variety of securities which are issued or guaranteed by the United States
Treasury, by various agencies of the United States Government, and by various
instrumentalities which have been established or sponsored by the United States
Government. The term also refers to "repurchase agreements" collateralized by
such securities.

<PAGE>   38
 
     U.S. Treasury Securities are backed by the "full faith and credit" of the
United States. Securities issued or guaranteed by Federal agencies and the U.S.
Government sponsored instrumentalities may or may not be backed by the full
faith and credit of the United States. In the case of securities not backed by
the full faith and credit of the United States, the investor must look
principally to the agency or instrumentality issuing or guaranteeing the
obligation for ultimate repayment, and may not be able to assert a claim against
the United States itself in the event the agency or instrumentality does not
meet its commitment.
 
     Some of the U.S. Government agencies that issue or guarantee securities
include the Export-Import Bank of the United States, Farmers Home
Administration, Federal Housing Administration, Maritime Administration, Small
Business Administration, and The Tennessee Valley Authority.
 
     An instrumentality of the U.S. Government is a government agency organized
under Federal charter with government supervision. Instrumentalities issuing or
guaranteeing securities include, among others, Federal Home Loan Banks, the
Federal Land Banks, Central Bank for Cooperatives, Federal Intermediate Credit
Banks, and the Federal National Mortgage Association.

ITEM 27. INDEMNIFICATION

     Insofar as indemnification for liability arising under the Securities Act
of 1933 may be permitted to trustees, directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a trustee, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such trustee, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.
 
ITEM 28. BUSINESS AND OTHER CONNECTIONS OF INVESTMENT ADVISER
 
     Investment advisory services are provided to the Registrant on an at-cost

divide or combine the Shares of a Series into a greater or lesser number of
Shares of such Series without thereby materially changing the proportionate
beneficial interest of such Shares in the assets held with respect to that
Series or materially affecting the rights of Shares of any other Series.

                  Section 2. Ownership of Shares. The ownership of Shares shall
be recorded on the books of the Trust or a transfer or similar agent for the
Trust, which books shall be maintained separately for the Shares of each Series.
No certificates evidencing the ownership of Shares shall be issued except as the
Board of Trustees may otherwise determine from time to time. The Trustees may
make such rules as they consider appropriate for the transfer of Shares of each
Series (or class) and similar matters. The record books of the Trust as kept by
the Trust or any transfer or similar agent, as the case may be, shall be
conclusive as to the identity of the Shareholders of each Series and as to the
number of Shares of each Series held from time to time by each Shareholder.

                  Section 3. Investments in the Trust. Investments may be
accepted by the Trust from such Persons, at such times, on such terms, and for
such consideration as the Trustees from time to time may authorize. Each
investment shall be credited to the Shareholder's account in the form of full
and fractional Shares of the Trust, in such Series (or class) as the purchaser
shall select, at the net asset value per Share next determined for such Series
(or class) after receipt of the investment; provided, however, that the Trustees
may, in their sole discretion, impose a sales charge or reimbursement fee upon
investments in the Trust.

                  Section 4. Status of Shares and Limitation of Personal
Liability. Shares shall be deemed to be personal property giving only the rights
provided in this instrument and the By-Laws of the Trust. Every Shareholder by
virtue of having become a Shareholder shall be held to have expressly assented
and agreed to the terms hereof. The death of a Shareholder during the existence
of the Trust shall not operate to terminate the Trust, nor entitle the
representative of any deceased Shareholder to an accounting or to take any
action in court or elsewhere against the Trust or the Trustees, but shall
entitle such representative only to the rights of said deceased Shareholder
under this Declaration of Trust. Ownership of Shares shall not entitle a
Shareholder to any title in or to the whole or any part of the Trust Property or
right to call for a partition or division of the same or for an accounting, nor
shall the ownership of Shares constitute the Shareholders as partners or joint
venturers. Neither the Trust nor the Trustees, nor any officer, employee or
agent of the Trust shall have any power to bind personally any Shareholder, or
to call upon any Shareholder for the payment of any sum of money or assessment
whatsoever other than such as the Shareholder may at any time agree to pay.

                  Section 5. Power of Board of Trustees to Change Provisions
Relating to Shares. Notwithstanding any other provision of this Declaration of
Trust to the contrary, and without limiting the power of the Board of Trustees
to amend the Declaration of Trust as provided elsewhere herein, the Board of
Trustees shall have the power to amend this Declaration of Trust, at any time
and from time to time, in such manner as the Board of Trustees may determine in
their sole discretion, without the need for Shareholder action, so as to add to,
delete, replace or otherwise modify any provisions relating to the Shares
contained in this Declaration of Trust, provided that before adopting any such
amendment without Shareholder approval the Board of Trustees shall determine
that it is consistent with the fair and equitable treatment of all Shareholders
and that Shareholder approval is not required by the 1940 Act or other
applicable law. If Shares have been issued, Shareholder approval shall be
required to adopt any amendments to this Declaration of Trust which would
adversely affect to a material degree the rights and preferences of the



                                      -5-
<PAGE>   7
Shares of any Series (or class) or to increase or decrease the par value of the
Shares of any Series (or class).

                  Section 6. Establishment and Designation of Shares. The
establishment and designation of any Series (or class) of Shares shall be
effective upon the adoption by a majority of the Trustees, of a resolution which
sets forth such establishment and designation and the relative rights and
preferences of such Series (or class). Each such resolution shall be
incorporated herein by reference upon adoption.

                  Shares of each Series (or class) established pursuant to this
Section 6, unless otherwise provided in the resolution establishing such Series,
shall have the following relative rights and preferences:

                  (a) Assets Held with Respect to a Particular Series. All
consideration received by the Trust for the issue or sale of Shares of a Series,
including dividends and distributions paid by, and reinvested in, such Series,
together with all assets in which such consideration is invested or reinvested,
all income, earnings, profits, and proceeds thereof from whatever source
derived, including, without limitation, any proceeds derived from the sale,
exchange or liquidation of such assets, and any funds or payments derived from
any reinvestment of such proceeds in whatever form the same may be, shall
irrevocably be held with respect to that Series for all purposes, subject only
to the rights of creditors, and shall be so recorded upon the books of account
of the Trust. Such consideration, assets, income, earnings, profits and proceeds
thereof, from whatever source derived, including, without limitation, any
proceeds derived from the sale, exchange or liquidation of such assets, and any
funds or payments derived from any reinvestment of such proceeds, in whatever
form the same may be, are herein referred to as "assets held with respect to"
that Series. In the event that there are any assets, income, earnings, profits
and proceeds thereof, funds or payments which are not readily identifiable as
assets held with respect to any particular Series (collectively "General
Assets"), the Trustees shall allocate such General Assets to, between or among
any one or more of the Series in such manner and on such basis as the Trustees,
in their sole discretion, deem fair and equitable, and any General Asset so
allocated to a



                                      -6-
<PAGE>   8
particular Series shall be held with respect to that Series. Each such
allocation by the Trustees shall be conclusive and binding upon the Shareholders
of all Series for all purposes in absence of manifest error.

                  (b) Liabilities Held with Respect to a Particular Series. The
assets of the Trust held with respect to each Series shall be charged with the
liabilities of the Trust with respect to such Series and all expenses, costs,
charges and reserves attributable to such Series, and any general liabilities of
the Trust which are not readily identifiable as being held in respect of a
Series shall be allocated and charged by the Trustees to and among any one or
more Series in such manner and on such basis as the Trustees in their sole
discretion deem fair and equitable. The liabilities, expenses, costs, charges,
and reserves so charged to a Series are herein referred to as "liabilities held
with respect to" that Series. Each allocation of liabilities, expenses, costs,
charges and reserves by the Trustees shall be conclusive and binding upon the
holders of all Series for all purposes in absence of manifest error. All Persons
who have extended credit which has been allocated to a particular Series, or who
have a claim or contract which has been allocated to a Series, shall look
exclusively to the assets held with respect to such Series for payment of such
credit, claim, or contract. In the absence of an express agreement so limiting
the claims of such creditors, claimants and contracting parties, each creditor,
claimant and contracting party shall be deemed nevertheless to have agreed to
such limitation unless an express provision to the contrary has been
incorporated in the written contract or other document establishing the
contractual relationship.

                  (c) Dividends, Distributions, Redemptions, and Repurchases. No
dividend or distribution including, without limitation, any distribution paid
upon termination of the Trust or of any Series (or class) with respect to, or
any redemption or repurchase of, the Shares of any Series (or class) shall be
effected by the Trust other than from the assets held with respect to such
Series, nor shall any Shareholder of any Series otherwise have any right or
claim against the assets held with respect to any other Series except to the
extent that such Shareholder has such a right or claim hereunder as a
Shareholder of such other Series. The Trustees shall have full discretion to



                                      -7-
<PAGE>   9
determine which items shall be treated as income and which items as capital; and
each such determination and allocation shall be conclusive and binding upon the
Shareholders in absence of manifest error.

                  (d) Voting. All Shares of the Trust entitled to vote on a
matter shall vote without differentiation between the separate Series on a
one-vote-per-Share basis; provided however, if a matter to be voted on affects
only the interests of not all Series (or class of a Series), then only the
Shareholders of such affected Series (or class) shall be entitled to vote on the
matter.

                  (e) Equality. All the Shares of each Series shall represent an
equal proportionate undivided interest in the assets held with respect to such
Series (subject to the liabilities of such Series and such rights and
preferences as may have been established and designated with respect to classes
of Shares within such Series), and each Share of a Series shall be equal to each
other Share of such Series.

                  (f) Fractions. Any fractional Share of a Series shall have
proportionately all the rights and obligations of a whole share of such Series,
including rights with respect to voting, receipt of dividends and distributions
and redemption of Shares.

                  (g) Exchange Privilege. The Trustees shall have the authority
to provide that the holders of Shares of any Series shall have the right to
exchange such Shares for Shares of one or more other Series in accordance with
such requirements and procedures as may be established by the Trustees.

                  (h) Combination of Series. The Trustees shall have the
authority, without the approval of the Shareholders of any Series unless
otherwise required by applicable law, to combine the assets and liabilities held
with respect to any two or more Series into assets and liabilities held with
respect to a single Series.

                  (i) Elimination of Series. At any time that there are no
Shares outstanding of a Series (or class), the Trustees may abolish such Series
(or class).

                                   ARTICLE IV.

                              The Board of Trustees

                  Section 1. Number, Election and Tenure. The number of Trustees
constituting the Board of Trustees shall be fixed from time to time by a written
instrument signed, or by resolution approved at a duly constituted meeting, by a
majority of the Board of Trustees, provided, however, that the number of
Trustees shall in no event be less than one (1) nor more than fifteen (15).
Subject to the requirements of Section 16(a) of the 1940 Act, the Board of
Trustees, by action of a majority of the then Trustees at a duly constituted
meeting, may fill vacancies in the Board of Trustees and remove Trustees with or
without cause. Each Trustee shall serve during the continued lifetime of the
Trust until he or she dies, resigns, is declared bankrupt or incompetent by a
court of competent jurisdiction, or is removed. Any Trustee may resign at any
time by written instrument signed by him and delivered to any officer of the
Trust or to a meeting of the Trustees. Such resignation shall be effective upon
receipt unless specified to be effective at some other time. Except to the
extent expressly provided in a written agreement with the Trust, no Trustee
resigning and no Trustee removed shall have any right to any compensation for
any period following his or her resignation or removal, or any right to damages
or other payment on account of such removal. Any Trustee may be removed at any
meeting of Shareholders by a vote of two-thirds of the outstanding Shares of the
Trust. A meeting of Shareholders for the purpose of electing or removing one or
more Trustees may be called (i) by the Trustees upon their own vote, or (ii)
upon the demand of Shareholders owning 10% or more of the Shares of the Trust in
the aggregate.

                  Section 2. Effect of Death, Resignation, etc. of a Trustee.
The death, declination, resignation, retirement, removal, or incapacity of one
or more Trustees, or all of them, shall not operate to annul the Trust or to
revoke any existing agency created pursuant to the terms of this Declaration of
Trust. Whenever a vacancy in the Board of Trustees shall occur, until such
vacancy is filled as provided in Article IV, Section 1, the Trustees in office,
regardless of their number, shall have


                                       -9-
<PAGE>   11
all the powers granted to the Trustees and shall discharge all the duties
imposed upon the Trustees by this Declaration of Trust.

                  Section 3. Powers. Subject to the provisions of this
Declaration of Trust, the business of the Trust shall be managed by the Board of
Trustees, and such Board shall have all powers necessary or convenient to carry
out that responsibility including the power to engage in transactions of all
kinds on behalf of the Trust. Trustees, in all instances, shall act as
principals and are and shall be free from the control of the Shareholders. The
Trustees shall have full power and authority to do any and all acts and to make
and execute any and all contracts, documents and instruments that they may
consider desirable, necessary or appropriate in connection with the
administration of the Trust. Without limiting the foregoing, the Trustees may:
adopt, amend and repeal By-Laws not inconsistent with this Declaration of Trust
providing for the regulation and management of the affairs of the Trust; elect
and remove such officers and appoint and terminate such agents as they consider
appropriate; appoint from their own number and establish and terminate one or
more committees consisting of two or more Trustees who may exercise the powers
and authority of the Board of Trustees to the extent that the Trustees
determine; employ one or more custodians of the assets of the Trust and may
authorize such custodians to employ subcustodians and to deposit all or any part
of such assets in a system or systems for the central handling of securities or
with a Federal Reserve Bank, retain a transfer agent or a shareholder servicing
agent, or both; provide for the issuance and distribution of Shares by the Trust
directly or through one or more Principal Underwriters or otherwise; redeem,
repurchase and transfer Shares pursuant to applicable law; set record dates for
the determination of Shareholders with respect to various matters; declare and
pay dividends and distributions to Shareholders of each Series from the assets
of such Series; establish from time to time, in accordance with the provisions
of Article III, Section 6 hereof, any Series of Shares, each such Series to
operate as a separate and distinct investment medium and with separately defined
investment objectives and policies and distinct investment purpose; and in
general delegate such authority as they consider desirable to any officer of the
Trust, to any committee of the Trustees and to any 



                                      -10-
<PAGE>   12
agent or employee of the Trust or to any such custodian, transfer or shareholder
servicing agent, Investment Manager or Principal Underwriter. Any determination
as to what is in the interests of the Trust made by the Trustees in good faith
shall be conclusive. In construing the provisions of this Declaration of Trust,
the presumption shall be in favor of a grant of power to the Trustees and unless
otherwise specified herein or required by the 1940 Act or other applicable law,
any action by the Board of Trustees shall be deemed effective if approved or
taken by a majority of the Trustees then in office or a majority of any duly
constituted committee of Trustees. Any action required or permitted to be taken
at any meeting of the Board of Trustees, or any committee thereof, may be taken
without a meeting if all members of the Board of Trustees or committee (as the
case may be) consent thereto in writing, and the writing or writings are filed
with the minutes of the proceedings of the Board of Trustees, or committee,
except as otherwise provided in the 1940 Act.

                  Without limiting the foregoing, the Trust shall have power and
authority:

                  (a) To invest and reinvest cash and cash items, to hold cash
uninvested, and to subscribe for, invest in, reinvest in, purchase or otherwise
acquire, own, hold, pledge, sell, assign, transfer, exchange, distribute, write

acquisition or delivery of all types of securities, futures contracts and
options thereon, and forward currency contracts of every nature and kind,
including, without limitation, all types of bonds, debentures, stocks, preferred
stocks, negotiable or non-negotiable instruments, obligations, evidences of
indebtedness, certificates of deposit or indebtedness, commercial paper,
repurchase agreements, bankers' acceptances, and other securities of any kind,
issued, created, guaranteed, or sponsored by any and all Persons, including,
without limitation, states, territories, and possessions of the United States
and the District of Columbia and any political subdivision, agency, or
instrumentality thereof, any foreign government or any political subdivision of
the U.S. Government or any foreign government, or any international
instrumentality or organization, or by any bank or savings institution, or by
any corporation or organization organized under the laws of the United States or
of any state, 



                                      -11-

contracts, to change the investments of the assets of the Trust; and to exercise
any and all rights, powers, and privileges of ownership or interest in respect
of any and all such investments of every kind and description, including,
without limitation, the right to consent and otherwise act with respect thereto,

powers, and privileges in respect of any of said instruments;

                  (b) To sell, exchange, lend, pledge, mortgage, hypothecate,

Trustees shall deem proper, granting to such person or persons such power and
discretion with relation to securities or property as the Trustees shall deem
proper;

                  (d) To exercise powers and right of subscription or otherwise
which in any manner arise out of ownership of securities;

                  (e) To hold any security or property in a form not indicating
that it is trust property, whether in bearer, unregistered or other negotiable
form, or in its own name or in the name of a custodian or subcustodian or a
nominee or nominees or otherwise or to authorize the custodian or a subcustodian
or a nominee or nominees to deposit the same in a securities depository, subject
in each case to the applicable provisions of the 1940 Act;

                  (f) To consent to, or participate in, any plan for the
reorganization, consolidation or merger of any corporation or issuer of any

such corporation or issuer; and to pay calls or subscriptions with respect to
any security held in the Trust;

                  (g) To join with other security holders in acting through a
committee, depositary, voting trustee or otherwise, and in that connection to

expenses and compensation of such committee, depositary or trustee as the
Trustees shall deem proper;

                  (h) To litigate, compromise, arbitrate, settle or otherwise
adjust claims in favor of or against the Trust or a Series, or any matter in
controversy, including but not limited to claims for taxes;

                  (i) To enter into joint ventures, general or limited
partnerships and any other combinations or associations;

                  (j) To borrow funds or other property in the name of the Trust

obligations of any Person; to make contracts of guaranty or suretyship, or
otherwise assume liability for payment thereof;

                  (l) To purchase and pay for entirely out of Trust Property
such insurance as the Trustees may deem necessary, desirable or appropriate for
the conduct of the business, including, without limitation, insurance policies
insuring the assets of the Trust or payment of distributions and principal on
its portfolio investments, and insurance policies insuring the Shareholders,
Trustees, officers, employees, agents, Investment Manager, principal
underwriters, or independent contractors of the Trust, individually against all
claims and liabilities of every nature arising by reason of holding Shares,
holding, being or having held any such office or position, or by reason of any
action alleged to have been taken or omitted by any such Person as Trustee,
officer, employee, agent, Investment Manager, Principal Underwriter, or
independent contractor, including any 


                                      -13-
<PAGE>   15
action taken or omitted that may be determined to constitute negligence, whether

liability; and

                  (m) To adopt, establish and carry out pension, profit-sharing,
share bonus, share purchase, savings, thrift and other retirement, incentive and
benefit plans, trusts and provisions, including the purchasing of life insurance
and annuity contracts as a means of providing such retirement and other
benefits, for any or all of the Trustees, officers, employees and agents of the
Trust.

                  The Trust shall not be limited to investing in obligations
maturing before the possible termination of the Trust or one or more of its
Series. The Trust shall not in any way be bound or limited by any present or
future law or custom in regard to investment by fiduciaries. The Trust shall not
be required to obtain any court order to deal with any assets of the Trust or
take any other action hereunder.
                
                  Section 4. Payment of Expenses by the Trust. Subject to the
provisions of Article III, Section 6(b), the Trustees are authorized to pay or
cause to be paid out of the principal or income of the Trust or Series, or
partly out of the principal and partly out of income, and to charge or allocate
the same to, between or among such one or more of the Series that may be
established or designated pursuant to Article III, Section 6, all expenses,
fees, charges, taxes and liabilities incurred or arising in connection with the
Trust or Series, or in connection with the management thereof, including, but
not limited to, the Trustees' compensation and such expenses and charges for the
services of the Trust's officers, employees, Investment Manager, Principal
Underwriter, auditors, counsel, custodian, transfer agent, Shareholder servicing
agent, and such other agents or independent contractors and such other expenses
and charges as the Trustees may deem necessary or proper to incur.

                  Section 5. Ownership of Assets of the Trust. Title to all of
the assets of the Trust shall at all times be considered as vested in the Trust,
except that the Trustees shall have power to cause legal title to any Trust
Property to be held by or in the name of one or more of the Trustees, or in the
name of the 


                                      -14-
<PAGE>   16
Trust, or in the name of any other Person as nominee, on such terms as the
Trustees may determine. Upon the resignation, incompetency, bankruptcy, removal,
or death of a Trustee he or she shall automatically cease to have any such title
in any of the Trust Property, and the title of such Trustee in the Trust
Property shall vest automatically in the remaining Trustees. Such vesting and
cessation of title shall be effective whether or not conveyancing documents have
been executed and delivered. The Trustees may determine that the Trust or the
Trustees, acting for and on behalf of the Trust, shall be deemed to hold
beneficial ownership of any income earned on the securities owned by the Trust,
whether domestic or foreign.

                  Section 6. Service Contracts.

                  (a) The Trustees may, at any time and from time to time,
contract for exclusive or nonexclusive advisory, management and/or
administrative services for the Trust or for any Series with any Person; and any
such contract may contain such other terms as the Trustees may determine,
including without limitation, authority for the Investment Manager to determine
from time to time without prior consultation with the Trustees what investments
shall be purchased, held, sold or exchanged and what portion, if any, of the
assets of the Trust shall be held uninvested and to make changes in the Trust's
investments, and such other responsibilities as may specifically be delegated to
such Person.

                  (b) The Trustees may also, at any time and from time to time,
contract with any Persons, appointing such Persons exclusive or nonexclusive
distributor or Principal Underwriter for the Shares of one or more of the Series
or other securities to be issued by the Trust. Every such contract may contain
such other terms as the Trustees may determine.

                  (c) The Trustees are also empowered, at any time and from time
to time, to contract with any Persons, appointing such Person(s) to serve as
custodian(s), transfer agent and/or shareholder servicing agent for the Trust or
one or more of its Series. Every such contract shall comply with such terms as
may be required by the Trustees.


                                      -15-
<PAGE>   17
                  (d) The Trustees are further empowered, at any time and from
time to time, to contract with any Persons to provide such other services to the
Trust or one or more of the Series, as the Trustees determine to be in the best
interests of the Trust and the applicable Series.

                  (e) The fact that:

                         (i) any of the Shareholders, Trustees, or officers of
                  the Trust is a shareholder, director, officer, partner,
                  trustee, employee, Manager, adviser, Principal Underwriter,
                  distributor, or affiliate or agent of or for any Person with
                  which an advisory, management or administration contract, or
                  Principal Underwriter's or distributor's contract, or
                  transfer, shareholder servicing or other type of service
                  contract may be made, or that

                         (ii) any Person with which an advisory, management or
                  administration contract or Principal Underwriter's or
                  distributor's contract, or transfer, shareholder servicing or
                  other type of service contract may be made also has an
                  advisory, management or administration contract, or principal
                  underwriter's or distributor's contract, or transfer,
                  shareholder servicing or other service contract, or has other
                  business or interests with any other Person,

shall not affect the validity of any such contract or disqualify any
Shareholder, Trustee or officer of the Trust from voting upon or executing the
same, or create any liability or accountability to the Trust or its
Shareholders, provided approval of each such contract is made pursuant to the
applicable requirements of the 1940 Act.

                                  ARTICLE V.

                    Shareholders' Voting Powers and Meetings

                  Section 1. Voting Powers. Subject to the provisions of Article
III, Sections 5 and 6(d), the Shareholders shall have right to vote only (i) for
the election or removal of Trustees as 


                                      -16-

provided in Article IV, Section 1, and (ii) with respect to such additional
matters relating to the Trust as may be required by the applicable provisions of
the 1940 Act, including Section 16(a) thereof, and (iii) on such other matters
as the Trustees may consider necessary or desirable. Each whole Share shall be
entitled to one vote as to any matter on which it is entitled to vote and each
fractional Share shall be entitled to a proportionate fractional vote. There
shall be no cumulative voting in the election of Trustees. Shares may be voted
in person or by proxy. A proxy purporting to be executed by or on behalf of a
Shareholder shall be deemed valid unless challenged at or prior to its exercise
and the burden of proving invalidity shall rest on the challenger.

                  Section 2. Voting Power and Meetings. Meetings of the
Shareholders may be called by the Trustees for the purposes described in Section
1 of this Article V. A meeting of Shareholders may be held at any place
designated by the Trustees. Written notice of any meeting of Shareholders shall
be given or caused to be given by the Trustees by delivering personally or
mailing such notice not more than ninety (90), nor less than ten (10) days
before such meeting, postage prepaid, stating the time and place of the meeting,
to each Shareholder at the Shareholder's address as it appears on the records of
the Trust. Whenever notice of a meeting is required to be given to a Shareholder
under this Declaration of Trust, a written waiver thereof, executed before or
after the meeting by such Shareholder or his or her attorney thereunto
authorized and filed with the records of the meeting, or actual attendance at
the meeting of Shareholders in person or by proxy, shall be deemed equivalent to
such notice.

                  Section 3. Quorum and Required Vote. Except when a larger
quorum is required by the applicable provisions of the 1940 Act, the presence in
person or by proxy of a majority of the Shares entitled to vote on a matter
shall constitute a quorum at a Shareholders' meeting. Any meeting of
Shareholders may be adjourned from time to time by a majority of the votes
properly cast upon the question of adjourning a meeting to another date and
time, whether or not a quorum is present, and the meeting may be held as
adjourned within a reasonable time after the date set for the original meeting
without further notice. Subject to the 


                                      -17-
<PAGE>   19
provisions of Article III, Section 6(d) and the applicable provisions of the
1940 Act, when a quorum is present at any meeting, a majority of the Shares
voted shall decide any questions except only a plurality vote shall be necessary
to elect Trustees.

                  Section 4. Action by Written Consent. Any action taken by
Shareholders may be taken without a meeting if all the holders of Shares
entitled to vote on the matter are provided with not less than 7 days written
notice thereof and written consent to the action is filed with the records of
the meetings of Shareholders by the holders of the number of shares that would
be required to approve the matter as provided in Article V, Section 3. Such
consent shall be treated for all purposes as a vote taken at a meeting of
Shareholders.

                  Section 5. Record Dates. For the purpose of determining the
Shareholders who are entitled to vote or act at any meeting or any adjournment
thereof, the Trustees may fix a time, which shall be not more than ninety (90)
nor less than ten (10) days before the date of any meeting of Shareholders, as
the record date for determining the Shareholders having the right to notice of
and to vote at such meeting and any adjournment thereof, and in such case only
Shareholders of record on such record date shall have such right,
notwithstanding any transfer of shares on the books of the Trust after the
record date. For the purpose of determining the Shareholders who are entitled to
receive payment of any dividend or of any other distribution, the Trustees may
fix a date, which shall be before the date for the payment of such dividend or
distribution, as the record date for determining the Shareholders having the
right to receive such dividend or distribution. Nothing in this Section shall be
construed as precluding the Trustees from setting different record dates for
different Series.

                                  ARTICLE VI.

                  Net Asset Value, Distributions, and Redemptions

                  Section 1. Determination of Net Asset Value, Net Income, and
Distributions. Subject to Article III, Section 6 hereof, the Trustees, in their
absolute discretion, may prescribe 


                                      -18-
<PAGE>   20
and shall set forth in the By-laws or in a duly adopted resolution of the
Trustees such bases and time for determining the per Share net asset value of
the Shares of any Series and the declaration and payment of dividends and
distributions on the Shares of any Series, as they may deem necessary or
desirable.

                  Section 2. Redemptions and Repurchases. The Trust shall
purchase such Shares as are offered by any Shareholder for redemption, upon
receipt by the Trust or a Person designated by the Trust that the Trust redeem
such Shares or in accordance with such procedures for redemption as the Trustees
may from time to time authorize; and the Trust will pay therefor the net asset
value thereof, in accordance with the By-Laws and the applicable provisions of
the 1940 Act. Payment for said Shares shall be made by the Trust to the
Shareholder within seven days after the date on which the request for redemption
is received in proper form. The obligation set forth in this Section 2 is
subject to the provision that in the event that any time the New York Stock
Exchange (the "Exchange") is closed for other than weekends or holidays, or if
permitted by the Rules of the Commission during periods when trading on the
Exchange is restricted or during any emergency which makes it impracticable for
the Trust to dispose of the investments of the applicable Series or to determine
fairly the value of the net assets held with respect to such Series or during
any other period permitted by order of the Commission for the protection of
investors, such obligations may be suspended or postponed by the Trustees.

                  The redemption price may in any case or cases be paid in cash
or wholly or partly in kind in accordance with Rule 18f-1 under the 1940 Act if
the Trustees determine that such payment is advisable in the interest of the
remaining Shareholders of the Series of which the Shares are being redeemed.
Subject to the foregoing, the selection and quantity of securities or other
property so paid or delivered as all or part of the redemption price shall be
determined by or under authority of the Trustees. In no case shall the Trust be
liable for any delay of any corporation or other Person in transferring
securities selected for delivery as all or part of any payment in kind.

                  Section 3. Redemptions at the Option of the Trust. The Trust
shall have the right, at its option, upon 30 days


                                      -19-
<PAGE>   21
notice to the affected Shareholder at any time to redeem Shares of any
Shareholder at the net asset value thereof as described in Section 1 of this
Article VI: (i) if at such time such Shareholder owns Shares of any Series
having an aggregate net asset value of less than a minimum value determined from
time to time by the Trustees; or (ii) to the extent that such Shareholder owns
Shares of a Series equal to or in excess of a maximum percentage of the
outstanding Shares of such Series determined from time to time by the Trustees;
or (iii) to the extent that such Shareholder owns Shares equal to or in excess
of a maximum percentage, determined from time to time by the Trustees, of the
outstanding Shares of the Trust.

                  Section 4. Transfer of Shares. The Trust shall transfer shares
held of record by any Person to any other Person upon receipt by the Trust or a
Person designated by the Trust of a written request therefore in such form and
pursuant to such procedures as may be approved by the Trustees.

                                  ARTICLE VII.

                    Compensation and Limitation of Liability

                  Section 1. Compensation of Trustees. The Trustees as such
shall be entitled to reasonable compensation from the Trust, and they may fix
the amount of such compensation from time to time. Nothing herein shall in any
way prevent the employment of any Trustee to provide advisory, management,
legal, accounting, investment banking or other services to the Trust and to be
specially compensated for such services by the Trust.

                  Section 2. Indemnification and Limitation of Liability. The
Trustees shall not be responsible or liable in any event for any neglect or
wrong-doing of any officer, agent, employee, Manager or Principal Underwriter of
the Trust, nor shall any Trustee be responsible for the act or omission of any
other Trustee, and, subject to the provisions of the Bylaws, the Trust out of
its assets may indemnify and hold harmless each and every Trustee and officer of
the Trust from and against any and all claims, demands, costs, losses, expenses,
and damages whatsoever arising out of or related to such Trustee's performance
of his or her duties as a Trustee or officer of the 


                                      -20-
<PAGE>   22
Trust; provided that nothing herein contained shall indemnify, hold harmless or
protect any Trustee or officer from or against any liability to the Trust or any
Shareholder to which he or she would otherwise be subject by reason of wilful
misfeasance, bad faith, gross negligence or reckless disregard of the duties
involved in the conduct of his or her office.

                  Every note, bond, contract, instrument, certificate or
undertaking and every other act or thing whatsoever issued, executed or done by
or on behalf of the Trust or the Trustees or any of them in connection with the
Trust shall be conclusively deemed to have been issued, executed or done only in
or with respect to their or his or her capacity as Trustees or Trustee, and such
Trustees or Trustee shall not be personally liable thereon.

                  Section 3. Trustee's Good Faith Action, Expert Advice, No Bond
or Surety. The exercise by the Trustees of their powers hereunder shall be
binding upon everyone interested in or dealing with the Trust. A Trustee shall
be liable to the Trust and to any Shareholder solely for his or her own wilful
misfeasance, bad faith, gross negligence or reckless disregard of the duties
involved in the conduct of the office of Trustee, and shall not be liable for
errors of judgment or mistakes of fact or law. The Trustees may take advice of
counsel or other experts with respect to the meaning and operation of this
Declaration of Trust, and shall be under no liability for any act or omission in
accordance with such advice nor for failing to follow such advice. The Trustees
shall not be required to give any bond as such, nor any surety if a bond is
required.

                  Section 4. Insurance. The Trustees shall be entitled and
empowered to the fullest extent permitted by law to purchase with Trust assets
insurance for liability and for all expenses reasonably incurred or paid or
expected to be paid by a Trustee or officer in connection with any claim,
action, suit or proceeding in which he or she becomes involved by virtue of his
or her capacity or former capacity with the Trust, whether or not the Trust
would have the power to indemnify him or her against such liability under the
provisions of this Article.

                                 ARTICLE VIII.

                                 Miscellaneous

                  Section 1. Liability of Third Persons Dealing with Trustees.
No Person dealing with the Trustees shall be bound to make any inquiry
concerning the validity of any transaction made or to be made by the Trustees or
to see to the application of any payments made or property transferred to the
Trust or upon its order.

                  Section 2. Termination of Trust or Series. Unless terminated
as provided herein, the Trust shall continue without limitation of time. The
Trust may be terminated at any time by the Trustees upon 60 days prior written
notice to the Shareholders. Any Series may be terminated at any time by the
Trustees upon 60 days prior written notice to the Shareholders of that Series.

                  Upon termination of the Trust (or any Series, as the case may
be), after paying or otherwise providing for all charges, taxes, expenses and
liabilities held, severally, with respect to each Series (or the applicable
Series, as the case may be), whether due or accrued or anticipated as may be
determined by the Trustees, the Trust shall, in accordance with such procedures
as the Trustees consider appropriate, reduce the remaining assets held,
severally, with respect to each Series (or the applicable Series, as the case
may be), to distributable form in cash or shares or other securities, and any
combination thereof, and distribute the proceeds held with respect to each
Series (or the applicable Series, as the case may be), to the Shareholders of
that Series, as a Series, ratably according to the number of Shares of that
Series held by the several Shareholders on the date of termination.

                  Section 3. Merger and Consolidation. The Trustees may cause
(i) the Trust or one or more of its Series to the extent consistent with
applicable law to be merged into or consolidated with another Trust, series or
Person, (ii) the Shares of the Trust or any Series to be converted into
beneficial interests in another business trust (or series thereof), (iii) the
Shares to be exchanged for assets or property under or pursuant to any 


                                      -22-
<PAGE>   24
state or federal statute to the extent permitted by law or (iv) a sale of assets
of the Trust or one or more of its Series. Such merger or consolidation, Share
conversion, Share exchange or sale of assets must be authorized by vote as
provided in Article V, Section 3 herein; provided that in all respects not
governed by statute or applicable law, the Trustees shall have power to
prescribe the procedure necessary or appropriate to accomplish a sale of assets,
Share exchange, merger or consolidation including the power to create one or
more separate business trusts to which all or any part of the assets,
liabilities, profits or losses of the Trust may be transferred and to provide
for the conversion of Shares of the Trust or any Series into beneficial
interests in such separate business trust or trusts (or series thereof).

                  Section 4. Amendments. This Declaration of Trust may be
restated and/or amended at any time by an instrument in writing signed by a
majority of the Trustees then holding office. Any such restatement and/or
amendment hereto shall be effective immediately upon execution and approval. The
Certificate of Trust of the Trust may be restated and/or amended by a similar
procedure, and any such restatement and/or amendment shall be effective
immediately upon filing with the Office of the Secretary of State of the State
of Delaware or upon such future date as may be stated therein.

                  Section 5. Filing of Copies, References, Headings. The
original or a copy of this instrument and of each restatement and/or amendment
hereto shall be kept at the office of the Trust where it may be inspected by any
Shareholder. Anyone dealing with the Trust may rely on a certificate by an
officer of the Trust as to whether or not any such restatements and/or
amendments have been made and as to any matters in connection with the Trust
hereunder; and, with the same effect as if it were the original, may rely on a
copy certified by an officer of the Trust to be a copy of this instrument or of
any such restatements and/or amendments. In this instrument and in any such
restatements and/or amendment, references to this instrument, and all
expressions like "herein," "hereof" and "hereunder," shall be deemed to refer to
this instrument as amended or affected by any such restatements and/or
amendments. Headings are placed herein for convenience of reference only and
shall not be taken as a part hereof or control or affect the meaning,
construction or 


                                      -23-
<PAGE>   25
effect of this instrument. Whenever the singular number is used herein, the same
shall include the plural; and the neuter, masculine and feminine genders shall
include each other, as applicable. This instrument may be executed in any number
of counterparts each of which shall be deemed an original.

                  Section 6. Applicable Law. This Agreement and Declaration of
Trust is created under and is to be governed by and construed and administered
according to the laws of the State of Delaware and the Delaware Business Trust
Act, as amended from time to time (the "Act"). The Trust shall be a Delaware
business trust pursuant to such Act, and without limiting the provisions hereof,
the Trust may exercise all powers which are ordinarily exercised by such a
business trust.

                  Section 7. Provisions in Conflict with Law or Regulations.

                  (a) The provisions of the Declaration of Trust are severable,
and if the Trustees shall determine, with the advice of counsel, that any of
such provisions is in conflict with the 1940 Act, the regulated investment
company provisions of the Internal Revenue Code or with other applicable laws
and regulations, the conflicting provision shall be deemed never to have
constituted a part of the Declaration of Trust; provided, however, that such
determination shall not affect any of the remaining provisions of the
Declaration of Trust or render invalid or improper any action taken or omitted
prior to such determination.

                  (b) If any provision of the Declaration of Trust shall be held
invalid or unenforceable in any jurisdiction, such invalidity or
unenforceability shall attach only to such provision in such jurisdiction and
shall not in any manner affect such provision in any other jurisdiction or any
other provision of the Declaration of Trust in any jurisdiction.

                  Section 8. Business Trust Only. It is the intention of the
Trustees to create a business trust pursuant to the Act, and thereby to create
only the relationship of trustee and beneficial owners within the meaning of
such Act between the Trustees and each Shareholder. It is not the intention of
the 


                                      -24-
<PAGE>   26
Trustees to create a general partnership, limited partnership, joint stock
association, corporation, bailment, joint venture, or any form of legal
relationship other than a business trust pursuant to such Act. Nothing in this
Declaration of Trust shall be construed to make the Shareholders, either by
themselves or with the Trustees, partners or members of a joint stock
association.

                  Section 9. Use of the Name "The Vanguard Group, Inc.". The
name "The Vanguard Group, Inc." and any variants thereof and all rights to the
use of the name "The Vanguard Group, Inc." or any variants thereof shall be the
sole and exclusive property of The Vanguard Group, Inc. ("VGI"). VGI has
permitted the use by the Trust of the identifying word "Vanguard" and the use of
the name "Vanguard" as part of the name of the Trust and the name of any Series
of Shares. Upon the Trust's withdrawal from the Amended and Restated Funds'
Service Agreement among the Trust, the other investment companies within the
Vanguard Group of Investment Companies and VGI, and upon the written request of
VGI, the Trust and any Series of Shares thereof shall cease to use or in any way
to refer to itself as related to "The Vanguard Group, Inc." or any variant
thereof.

                          INDEMNIFICATION AND INSURANCE

                                      -8-
<PAGE>   9
                  SECTION 1. AGENTS, PROCEEDINGS AND EXPENSES. For the purpose
of this Article, "agent" means any person who is or was a Trustee or officer of
this Trust and any person who, while a trustee or officer of this Trust, is or
was serving at the request of this Trust as a Trustee, director, officer,
partner, employee, or agent of another foreign or domestic corporation,
partnership, joint venture, trust or other enterprise; "Trust" includes any
domestic or foreign predecessor entity of this Trust in a merger, consolidation,
or other transaction in which the predecessor's existence ceased upon
consummation of the transaction; "proceeding" means any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative,
or investigative; and "expenses" includes without limitation attorney's fees and
any expenses of establishing a right to indemnification under this Article.

                  SECTION 2. ACTIONS OTHER THAN BY TRUST. This Trust shall
indemnify any person who was or is a party or is threatened to be made a party
to any proceeding (other than an action by or in the right of this Trust) by
reason of the fact that such person is or was an agent of this Trust, against
expenses, judgments, fines, settlements and other amounts actually and
reasonably incurred in connection with such proceeding, if it is determined that
person acted in good faith and reasonably believed: (a) in the case of conduct
in his official capacity as an agent of the Trust, that his conduct was in the
Trust's best interests and (b) in all other cases, that his conduct was at least
not opposed to the Trust's best interests and (c) in the case of a criminal
proceeding, that he had no reasonable cause to believe the conduct of that
person was unlawful. The termination of any proceeding by judgment, order or
settlement shall not of itself create a presumption that the person did not meet
the requisite standard of conduct set forth in this Section. The termination of
any proceeding by conviction, or a plea of nolo contendere or its equivalent, or
an entry of an order of probation prior to judgment, creates a rebuttable
presumption that the person did not meet the requisite standard of conduct set
forth in this Section.

                  SECTION 3. ACTIONS BY THE TRUST. This Trust shall indemnify
any person who was or is a party or is threatened to be made a party to any
proceeding by or in the right of this Trust to procure a judgment in its favor
by reason of the fact that that person is or was an agent of this Trust, against
expenses actually and reasonably incurred by that person in connection with the
defense or settlement of that action if that person acted in good faith, in a
manner that person believed to be in the best interests of this Trust and with
such care, including reasonable inquiry, as an ordinarily prudent person in a
like position would use under similar circumstances.

                                      -9-
<PAGE>   10
                  SECTION 4. EXCLUSION OF INDEMNIFICATION. Notwithstanding any
provision to the contrary contained herein, there shall be no right to
indemnification for any liability arising by reason of willful misfeasance, bad
faith, gross negligence, or the reckless disregard of the duties involved in the
conduct of the agent's office with this Trust.

                  No indemnification shall be made under Sections 2 or 3 of this
Article:

                  (a)     In respect of any proceeding as to which that person
                          shall have been adjudged to be liable on the basis
                          that personal benefit was improperly received by him,
                          whether or not the benefit resulted from an action
                          taken in the person's official capacity; or

                  (b)     In respect of any proceeding as to which that person
                          shall have been adjudged to be liable in the
                          performance of that person's duty to this Trust,
                          unless and only to the extent that the court in which
                          that action was brought shall determine upon
                          application that in view of all the relevant
                          circumstances of the case, that person is fairly and
                          reasonably entitled to indemnity for the expenses
                          which the court shall determine; however, in such
                          case, indemnification with respect to any proceeding
                          by or in the right of the Trust or in which liability
                          shall have been adjudged by reason of the disabling
                          conduct set forth in the preceding paragraph shall be
                          limited to expenses; or


                  (c)     Of amounts paid in settling or otherwise disposing of
                          a proceeding, with or without court approval, or of
                          expenses incurred in defending a proceeding which is
                          settled or otherwise disposed of without court
                          approval, unless the required approval set forth in
                          Section 6 of this Article is obtained.

                  SECTION 5. SUCCESSFUL DEFENSE BY AGENT. To the extent that an
agent of this Trust has been successful, on the merits or otherwise, in the
defense of any proceeding referred to in Sections 2 or 3 of this Article before
the court or other body before whom the proceeding was brought, the agent shall
be indemnified against expenses actually and reasonably incurred by the agent in
connection therewith, provided that the Board of Trustees, including a majority
who are disinterested, non-party Trustees, also determines that based upon a
review of the facts, 



                                      -10-
<PAGE>   11

Article and is not prohibited from indemnification because of the disabling
conduct set forth in Section 4 of this Article, by:

                  (a)     A majority vote of a quorum consisting of Trustees who
                          are not parties to the proceeding and are not
                          interested persons of the Trust (as defined in the

any proceeding may be advanced by this Trust before the final disposition of the
proceeding if (a) receipt of a written affirmation by the agent of his good
faith belief that he has met the standard of conduct necessary for
indemnification under this Article and a written undertaking by or on behalf of
the agent, such undertaking being an unlimited general obligation to repay the
amount of the advance if it is ultimately determined that he has not met those
requirements, and (b) a determination that the facts then known to those making
the determination would not preclude indemnification under this Article.

the manner specified in Section 6 of this Article for determining that the
indemnification is permissible.

                  SECTION 8. OTHER CONTRACTUAL RIGHTS. Nothing contained in this

                          effect at the time of accrual of the alleged cause of
                          action asserted in the proceeding in which the
                          expenses were incurred or other amounts were paid
                          which prohibits or otherwise limits indemnification;
                          or

              SECOND AMENDED AND RESTATED FUNDS' SERVICE AGREEMENT



         This second Amended and Restated Funds' Service Agreement, made as of
the 10th day of May, 1993 (the "Agreement"), between and among the 33 investment
companies registered under the Investment Company Act of 1940 ("1940 Act"),
whose names are set forth on the signature page of this Agreement, which
together with any additional investment companies which may become a party to
this Agreement pursuant to Section 5.4 are collectively called the "Funds"; and
The Vanguard Group, Inc., a Pennsylvania corporation ("Service Company").

         Whereas, each of the Funds has heretofore determined (as evidenced by,
among many documents, prior versions* of this Agreement (the "Prior
Agreements"), and by prospectuses and proxy statements of the Funds related
thereto): (i) to manage and perform the corporate management, administrative and
share distribution functions required for its continued operation, (ii) to
create a structure which enhances the independence of the Funds from the
providers of external services, (iii) to share, on an equitable and fair basis,
with all of the other Funds the expenses of establishing the means to accomplish
these objectives at the lowest reasonable cost; and

         Whereas, each of the Funds: (i) has heretofore determined that these
objectives can best be accomplished by establishing a company: (a) to be
wholly-owned by the Funds; (b) to provide corporate management, administrative,
and distribution services, and upon the reasonable request of any Fund to
provide other service to such Fund at cost; (c) to employ the executive,
managerial, administrative, secretarial and clerical personnel necessary or
appropriate to perform such services; and (d) to acquire such assets and to
obtain such facilities and equipment as are necessary or appropriate to carry
out such services, and to make those assets available to the Funds; and (ii)
since May 1, 1975 (or the commencement of its operations after this date) has
utilized Service Company, pursuant to the provisions of the Prior Agreements;
and

         Whereas, each of the Funds recognizes that it may, from time to time,
be in the best interests of the Funds (i) for Service Company to provide similar
services to investment companies other than the Funds, (ii) for the Funds to
organize, from time to time, new investment companies which are intended to
become parties to this Agreement; and, (iii) for Service Company to engage in
business activities (directly or through subsidiaries), supportive of the Funds'
operations as investment companies; and

         Whereas, each of the Funds desires to enter into a completely
integrated Seconded Amended and Restated Funds' Service Agreement with the other
Funds to set forth the current terms and provisions of the relationships which
the Funds have determined to establish;
         Now, Therefore, each Fund agrees with each and all of the other Funds,
and with Service Company, as follows:

terms and provisions of the purchase. Provided, however, that:

                  A. Without the consent of all of the Funds, the date for the
         purchase of Shares or other securities shall not be less than 15 days

         Shares or other securities, expressed as a percentage of the total
         purchase price for the additional securities to be paid by all of the

         of the Fund bears to the aggregate current net assets of all of the
         Funds as of the most recent month-end preceding the purchase date.

re-establish periodically a fair and proportionate ratio of cash investments by
each Fund in the Service Company as compared to its then current net assets,

or more of the Funds, sufficient Shares or other securities to re-establish the
ratio.

                  A. Such purchases and sales shall be made (1) as of the last
         business day of any month upon the addition or withdrawal of any Fund
         as a party to this Agreement, provided that if the addition or
         withdrawal of a Fund creates no material disparity in the ratios (as
         determined by the Service Company's Board of Directors), and no Fund
         requests that an adjustment be made, the adjustment may be deferred
         until the close of the Service Company's fiscal year; (2) in connection
         with additional investments pursuant to Section 1.2; and (3) annually
         as of the close of the Service Company's fiscal year, on a date fixed

         requests that an adjustment be made.

Purchases. Notwithstanding the provisions of Sections 1.1, 1.2 and 1.3, above,

business affairs of a Fund so long as the Fund remains a party to this
Agreement.

                  purpose of the expenditure, (ii) the benefits, if any, to be
                  derived directly by each Fund relative to the benefits derived
                  by other Funds, (iii) the need or desirability for the Funds
                  as a group to provide competitive investment programs and
                  services at competitive prices for the group to survive and
                  grow, (iv) the benefits which each Fund derives by being a
                  member of a strong Fund group, and (v) such other factors as
                  the Board considers relevant to the specific expenditure and
                  allocation.

                  B. Distribution Expenses. Each of the Funds expressly agrees
         to pay to Service Company, as requested, the Fund's portion of the
         actual cost of distributing shares of the Funds, which shall mean its
         share of all of the direct and indirect expenses of a marketing and
         promotional nature including, but not limited to, advertising, sales
         literature and sales personnel, as well as expenditures on behalf of
         any newly organized registered investment company which is to become a
         party of this Agreement pursuant to Section 5.4. The cost of
         distributing shares of the Funds shall not include distribution-related
         expenses of an administrative nature, which shall be allocated among
         the Funds pursuant to Section 3.2(A). Distribution expenses of a
         marketing and promotional nature shall be allocated 
<PAGE>   6
         among the Funds in the manner approved by the Securities and Exchange
         Commission in Investment Company Act Release No. 11645 (Feb. 25, 1981):

                        (1) 50% of these expenses will be allocated based upon
                each Fund's average month-end assets during the preceding
                quarter relative to the average month-end assets during
                preceding quarter of the Funds as a group. 

                        (2) 50% of these expenses will be allocated initially
                among the Funds based upon each Fund's sales for the 24 months
                ended with the last day of the preceding quarter relative to the
                sales of the Funds as a group for the same period. (Shares
                issued pursuant to a reorganization shall be excluded from the
                sales of a Fund and the Funds as a group.) 

                        (3) Provided, however, that no Fund's aggregate
                quarterly contribution for distribution expenses, expressed as a
                percentage of its assets, shall exceed 125% of the average
                expenses for the Funds as a Group, expressed as a percentage of
                the total assets of the Funds. Expenses not charged to a
                particular Fund(s) because of this 125% limitation shall be
                re-allocated to other Funds on iterative basis; and that no
                Fund's annual expenses for distribution shall exceed 0.2% of its
                average month-end net assets.

                       IV. CONCERNING THE SERVICE COMPANY

         4.1 Name. Each Fund acknowledges and agrees:

                  A. that the name "The Vanguard Group, Inc.", and any variants
         thereof used to identify (1) the Funds as a group, (2) any Fund as a
         member of a group being served by Service Company, or (3) any other
         person as being served or related to Service Company (whether now in
         existence or hereafter created), shall be the sole and exclusive
         property of Service Company, its affiliates and its successors.

                  B. That Service Company shall have the sole and exclusive
         right to permit the use of said name or variants thereof so long as
         this Agreement or any amendments thereto are effective.

                  C. That upon its withdrawal from this Agreement and upon the
         written request of Service Company, the Fund shall cease to use, or in
         any way to refer to itself as related to, "The Vanguard Group, Inc." or
         any variant thereof.

                  The foregoing agreements on the part of each Fund are hereby
         made binding upon it, its directors, officers, shareholders and
         creditors and all other persons claiming under or through it.

         4.2 Services to Others. The Service Company may render services to any
person other than the Funds so long as:

                  A. The services to be rendered to the Funds hereunder are not
         impaired thereby.

                  B. The terms and provisions upon which the services are to be
         rendered have been approved by the holders of a majority of the Shares.

                  C. The services rendered for compensation and, to the extent
         achievable, for the purpose of gaining a profit thereon.
<PAGE>   7
                  D. Any income earned and fees received by Service Company
         shall be used to reduce the total costs and expenses of Service
         Company.

         4.3 Books, Records and Audits of Service Company. The Service Company,
and any subsidiary established pursuant to Section 3.1(C), shall maintain
complete, accurate and current books, records and financial statements
concerning its activities. To the extent appropriate it will preserve said
records in the manner and for the periods prescribed by law. Financial records
and statements shall be kept in accord with generally accepted accounting
principles and shall be audited at least annually by independent public
accountants (who may also be accountants for any of the Funds). Within 120 days
after the close of Service Company's fiscal year it shall deliver to each Fund a
copy of its audited financial statements for that year and the accountants
report thereon. Service Company, on behalf of itself and any subsidiary,
acknowledges that all of the records they shall prepare and maintain pursuant to
this Agreement shall be the property of the Funds and that upon a request of any
Fund they shall make the Fund's records available to it, along with such other
information and data as are reasonably requested by the Fund, for inspection,
audit or copying, or turn said records over to the Fund.

         4.4 Indemnification.

                  A. Each Fund (herein the "Indemnitor") agrees to indemnify,
         hold harmless and reimburse (herein "indemnify") every other Fund,
         Service Company and/or any subsidiary of Service Company (herein the
         "Indemnitee"):

                           (1) which Indemnitee (a) was or is a party to, or is
                  threatened to be made a party to, any threatened, pending or
                  completed action, suit or proceeding, whether civil, criminal,
                  administrative or investigative (herein a "suit"), or (b)
                  incurs an actual economic loss or expense (herein a "loss").

                           (2) if: (a) such suit or loss arises from an action
                  or failure to act, event, occurrence, transaction or other
                  analogous happening (herein an "event") under circumstances in
                  which the indemnitee is involved in a suit or incurs a loss.

                                    (i) as a result substantially of, or
                           attributable primarily to, its being a party to this
                           Agreement, or to its indirect participation in
                           transactions contemplated by this Agreement; and

                                    (ii) where the suit or loss arises primarily
                           and substantially from an event related primarily and
                           substantially to the business and/or operations of
                           the Indemnitor; and 

                                   (b) an independent third party, who may but
                           need not be legal counsel for the Funds, advises the
                           Funds in writing (I) that the condition set forth in
                           "(1)" and "(2)(a)" have occurred and (ii) that the
                           Indemnitee is without significant fault or
                           responsibility for the suit or loss as measured by
                           the comparative conduct of the Indemnitor and
                           Indemnitee and by the purposes sought to be
                           accomplished by this Agreement.

                  B. The financial obligations of the Indemnitor under this
         Section shall be limited to:
                  
                           (1) In the case of a suit, to expenses (including
                  attorneys' fees), actually incurred by the Indemnitee. The
                  termination of any suit by judgment, order, settlement, or
                  upon a plea of nolo contendere or its equivalent, shall not,
                  of itself, 
<PAGE>   8
                  create a presumption that the Indemnitee is not entitled to be
                  indemnified hereunder.

                           (2) In the case of an event, to losses and/or
                  expenses (including attorneys' fees) actually incurred by the
                  Indemnitee.

                           The Indemnitee shall not be liable financially
                  hereunder for lost profits in the case of either a suit or
                  loss.

                  C. Expenses incurred in defending a suit or resolving an event
         may be paid by the prospective Indemnitor in advance of the final
         disposition of such suit or event if authorized by the Board of
         Directors of the prospective Indemnitor in the specific case upon
         receipt of an undertaking by or on behalf of the prospective indemnitee
         to repay such amount unless it shall ultimately be determined that the
         Indemnitee is entitled to be indemnified by the Indemnitor as provided
         in this Section.

                  D. The indemnification provided by this Section shall not be
         deemed exclusive of any other rights to which the Indemnitee may be
         entitled under any agreement or otherwise.

                              V. TERM OF AGREEMENT

         5.1 Effective Period. This Agreement shall become effective on the date
first written above, and shall continue in full force and effect as to all
parties hereto until terminated or amended by mutual agreement of all parties
hereto. The withdrawal pursuant to Section 5.2(A) or 5.2(B) of one or more of
the Funds from this Agreement shall not affect the continuance of this Agreement
except as to the parties withdrawing.

         5.2 Withdrawal from Agreement.

                  A. Any Fund may elect to withdraw from this Agreement
         effective at the end of any monthly period by giving at least 90 days'
         prior written notice to each of the parties to this Agreement. Upon the
         written demand of all other Funds which are parties to this Agreement a
         Fund shall withdraw, and in the event of its failure to do so shall be
         deemed to have withdrawn, from this Agreement; such demand shall
         specify the date of withdrawal which shall be at the end of any monthly
         period at least 90 days from the time of service of such demand.

                  B. In the event of the withdrawal of any Fund from this
         Agreement, all its rights and obligations, except for lease
         commitments, under this Agreement (except such rights or obligations as
         have accrued prior to the date of withdrawal) shall terminate as of the
         date of the withdrawal. The withdrawing Fund shall surrender its Shares
         to Service Company, and (1) shall be entitled to receive from Service
         Company an amount equal to the excess of the fair value of (i) its
         Shares of other securities Service Company as of the date of its
         withdrawal less (ii) its proportionate interest in any liabilities of
         Service Company, including when appropriate any commitments of Service
         Company and unexpired leases at the date of withdrawal; (2) shall be
         obligated to pay to Service Company an amount equal to the excess of
         (ii) over (i). Such amount to be received from or paid to Service
         Company shall be determined by the favorable vote of the holders of a
         majority of the Shares whose determination shall be conclusive upon the
         Funds. Any amount found payable by Service Company to the withdrawing
         Fund shall be recoverable 
<PAGE>   9
         by Service Company from the Funds remaining under this Agreement in 
         accordance with the provisions of Sections 1.2, 1.3 and 1.4 hereof. 


         5.3 Termination by Mutual Consent. In the event that all Funds withdraw
from this Agreement without entering into a comparable successor agreement, each
Fund shall surrender its Shares to Service Company and after payment by Service
Company of all its liabilities, including the settlement of unexpired lease
obligations, shall:

                  A. Receive from Service Company in cash an amount equal to its
         proportionate share of the actual value of all assets of the Service
         Company which can be reduced readily to cash.

                  B.  Negotiate in good faith with the other Funds provision for
         the equitable use and/or disposition of assets of the Service Company 
         which are not readily reducible to cash.

         5.4 Additional Parties to Agreement. Upon the favorable vote of
two-thirds of the shareholders and of the holders of two-thirds of the Shares of
the Service Company, any investment company registered under the Investment
Company Act of 1940 may become a party to this Agreement and share as a Fund in
all of the rights, duties and liabilities hereunder by adopting, executing and
delivering to the Service Company and the Funds a signed copy of this Agreement
which shall evidence that investment company's agreement to assume the duties
and obligations of a Fund hereunder. Upon the delivery of a signed copy of this
Agreement, the new Fund shall be subject to all the provisions of this Agreement
and become a holder of Shares by adjustment in cash investments among the Funds
pursuant to Section 1.3. No person shall become a holder of Shares without
becoming a party to this Agreement.


                                   VI. GENERAL

         6.1 Definition of Certain Terms. As used in this Agreement, the terms
set forth below shall mean:

                  A. "Fair Value of Shares" shall mean the proportionate
         interest, as represented by the ratio of the number of Shares owned by
         a Fund to the number of Shares issued and outstanding, in all assets of
         the Service Company less all liabilities of the Service Company on the
         date fair value is to be determined. Assets shall be valued at fair
         market value. In case of any dispute as to the proportionate interest
         of any Fund or as to the fair value of the Shares, the issue shall be
         determined by the favorable vote of the holders of a majority of the
         Shares, whose determination shall be conclusive upon the Fund.

                  B. "Person" shall mean a natural person, a corporation, a
         partnership, an association, a joint-stock company, a trust, a fund or
         any organized group of persons whether incorporated or not.

         6.2 Assignment. This Agreement shall bind and inure to the benefit of
the parties thereto, their respective successors and assigns.

         6.3 Captions. The captions in this Agreement are included for
convenience of reference only and in no way define any of the provisions hereof
or otherwise affect their construction or effect.
<PAGE>   10
         6.4 Amendment. Unless prohibited by applicable laws, regulations or
orders of regulatory authorities and except as set forth below, this Agreement
may be amended at any time and in one or more respects upon the favorable vote
of the holders of a majority of the Shares (except that the vote required in
Sections 3.1 and 5.4 may be amended only by the favorable votes of the number of
holders or Shares specified therein) and without the further approval or vote of
shareholders of any of the Funds; provided, however, that Section 1.4 (limiting
cash investments by the Funds in Service Company) may not be amended unless an
exemptive order permitting such amendment is obtained from the U.S. Securities
and Exchange Commission.

         6.5 Severability. If any provision of this Agreement shall beheld or
made invalid by a court decision, statute, rule or otherwise, the remainder of
this Agreement shall not be affected thereby.

         In Witness Whereof, each of the parties hereto has caused the Agreement
to be signed and its corporate seal to be hereto affixed by its proper officers
thereunto duly authorized, all as of the date and year first above written.

Vanguard Treasury Fund
P.O. Box 2600
Valley Forge, PA 19482
 
Gentlemen:
 
     Vanguard Treasury Fund (the "Fund") was organized under the laws of the
State of Delaware on August 20, 1996. I am acting as counsel to the Fund in
connection with the Fund's initial registration as an open-end management
investment company under the Investment Company Act of 1940 ("1940 Act"), as
amended. It is in my capacity as counsel to the Fund that I am furnishing you
this opinion.
 
     I have examined the Fund's: (1) Agreement and Declaration of Trust
("Declaration of Trust"); (2) By-Laws; (3) minutes of the meetings of the Board
of Trustees; (4) Notification of Registration on Form N-8A under the 1940 Act;
(5) Registration Statement on Form N-1A under the Securities Act of 1933 ("1933"
Act) and 1940 Act; (6) registration statements, application and other documents
filed with various state securities authorities; and (7) all other relevant
documents and records, as well as the procedures and requirements relative to
the issuance and sale of the Fund's shares.
 
     Based upon the foregoing information and my examination, it is my opinion
that:
 
     1. The Fund is a valid and existing business trust of the State of Delaware
authorized to issue an unlimited number of shares of beneficial interest with a
par value, of $.001. The Board of Trustees has the power to divide the shares
into series ("Portfolios") and divide the series into separate classes of shares
of beneficial interest. Currently, the Fund is offering one Portfolio.
 
     2. The Fund is filing herewith a Registration Statement with the U.S.
Securities and Exchange Commission on Form N-1A to register as an open-end
management company under the 1940 Act and to register an indefinite number of
its securities under the 1933 Act.
 
     3. The Fund will be filing registration statements, applications and/or
other documents required to register its securities under various State
securities laws.
 
     4. The Fund will be authorized to offer and sell its shares when all
necessary Federal and State regulatory authorizations, which are prerequisite to
the issuance of the Fund's shares, have been obtained, subject to the Fund's
continuing to maintain the effectiveness of the requisite Registration Statement
under the 1933 Act and certain of the State securities laws.
 
     5. Such shares, when issued for consideration deemed by the Board of
Trustees to be consistent with the Fund's Declaration of Trust, will be legally
authorized, fully paid and non-assessable.
 
     6. The holders of the Fund's shares will have all the rights provided with
respect to such holdings by the Declaration of Trust and the laws of the State
of Delaware.
 
     I hereby consent to use of this opinion as an Exhibit to the Fund's
Registration Statement on Form N-1A filed under the 1933 and 1940 Acts, and to
the applications and registration statements, and amendments thereto, filed in
accordance with the securities laws of the states in which shares of the Fund
are offered. I further consent to reference in the Prospectus of the Fund to the
fact that this opinion concerning the legality of the issue has been rendered by
me.
 
Very truly yours,
