INTRODUCTION
- --------------------------------------------------------------------------------

J.P. MORGAN INSTITUTIONAL U.S. EQUITY FUNDS

These funds invest primarily in U.S. stocks either directly or through another
fund. As a shareholder, you should anticipate risks and rewards beyond those of
a typical bond fund or a typical balanced fund.

WHO MAY WANT TO INVEST

The funds are designed for investors who:

- - are pursuing a long-term goal such as retirement

- - want to add an investment with growth potential to further diversify a
portfolio

- - want funds that seek to outperform the markets in which they each invest
over the long term

- - with regard to the Tax Aware Fund, are individuals that could benefit from
a strategy that pursues returns from an after-tax perspective

The funds are NOT designed for investors who:

- - want funds that pursue market trends or focus only on particular industries
or sectors

- - require regular income or stability of principal

- - are pursuing a short-term goal or investing emergency reserves

- - with regard to the Tax Aware Fund, are investing through a tax-deferred
account such as an IRA

J.P. MORGAN

Known for its commitment to proprietary research and its disciplined investment
strategies, J.P. Morgan is the asset management choice for many of the world's
most respected corporations, financial institutions, governments, and
individuals. Today, J.P. Morgan employs over 300 analysts and portfolio managers
around the world and has more than $240 billion in assets under management,
including assets managed by the funds' advisor, Morgan Guaranty Trust Company of
New York.

- --------------------------------------------------------------------------------
BEFORE YOU INVEST

Investors considering these funds should understand that:

- - The value of each fund's shares will fluctuate over time. You could lose
money if you sell when your fund's share price is lower than when you
invested.

- - There is no assurance that these funds will meet their investment goals.

- - Future returns will not necessarily resemble past performance.

- - These funds (except for the Tax Aware Fund) invest in another fund with an
identical goal -- the master portfolio. The Tax Aware Fund invests directly
in individual securities.

<PAGE>

U.S. EQUITY MANAGEMENT APPROACH
- --------------------------------------------------------------------------------

The J.P. Morgan Institutional U.S. equity funds invest primarily in U.S. stocks.
The Tax Aware Fund does so while seeking to enhance the after-tax returns of its
shareholders.

While each fund follows its own strategy, the funds as a group share a single
investment philosophy. This philosophy, developed by the funds' advisor, focuses
on stock picking while largely avoiding sector or market-timing strategies.
Also, under normal market conditions, each fund will remain fully invested.

U.S. EQUITY INVESTMENT PROCESS

In managing the funds described in this prospectus, J.P. Morgan employs a three-
step process:

[GRAPHIC]
J.P. Morgan analysts develop proprietary fundamental research

RESEARCH J.P. Morgan takes an in-depth look at company prospects over a
relatively long period -- often as much as five years -- rather than focusing on
near-term expectations. This approach is designed to provide insight into a
company's real growth potential. J.P. Morgan's in-house research is developed by
an extensive worldwide network of over 120 career analysts. The team of analysts
dedicated to U.S. equities includes more than 20 members, with an average of
over ten years of experience.

[GRAPHIC]
Stocks in each industry are ranked with the help of models

VALUATION The research findings allow J.P. Morgan to rank the companies in each
industry group according to their relative value. The greater a company's
estimated worth compared to the current market price of its stock, the more
undervalued the company. The valuation rankings are produced with the help of a
variety of models that quantify the research team's findings.

[GRAPHIC]
Using research and valuations, each fund's management team chooses stocks for
its fund

STOCK SELECTION Each fund buys and sells stocks according to its own policies,
using the research and valuation rankings as a basis. In general, each
management team buys stocks that are identified as undervalued and considers
selling them when they appear overvalued. Along with attractive valuation, the
funds' managers often consider a number of other criteria:

- - catalysts that could trigger a rise in a stock's price

- - high potential reward compared to potential risk

- - temporary mispricings caused by market overreactions

2 U.S. EQUITY MANAGEMENT APPROACH

<PAGE>

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

THE SPECTRUM OF U.S. EQUITY FUNDS

The funds described in this prospectus pursue a range of goals and offer varying
degrees of risk and potential reward. Differences between these funds include:

- - how much emphasis they give to the most undervalued stocks

- - how closely they follow the industry weightings of their benchmarks

- - how many securities they typically maintain in their portfolios

- - the size or market capitalization of the companies in which they invest

- - whether they focus on before-tax or after-tax returns

The table below shows degrees of the relative risk and return that these funds
potentially offer. These and other distinguishing features of each U.S. equity
fund are described on the following pages.

POTENTIAL RISK AND RETURN
- --------------------------------------------------------------------------------

[CHART]

The positions of the funds in this graph reflect long-term performance goals
only, and are relative, not absolute.

TAX AWARE INVESTING AT J.P. MORGAN

The Tax Aware Fund is designed to reduce, but not eliminate, capital gains
distributions to shareholders. In doing so, the fund sells securities when the
anticipated performance benefit justifies the resulting tax liability. This
strategy often includes holding securities long enough to avoid higher,
short-term capital gains taxes, selling shares with a higher cost basis first,
and offsetting gains realized in one security by selling another security at a
capital loss. The fund is aided in this process by a tax-sensitive optimization
model developed by J.P. Morgan.

The Tax Aware Fund generally intends to pay redemption proceeds in cash; however
it reserves the right at its sole discretion to pay redemptions over $500,000
in-kind as a portfolio of representative stocks rather than cash. An in-kind
redemption payment can shield the fund -- and other shareholders -- from tax
liabilities that might otherwise be incurred. At the same time, it can give the
redeeming shareholder greater flexibility in managing tax consequences of the
redemption and is not subject to a redemption fee by the fund. However, the
stocks received will continue to fluctuate in value after redemption and will be
subject to brokerage or other transaction costs when liquidated.

(J.P. MORGAN INSTITUTIONAL DISCIPLINED EQUITY FUND)

[GRAPHIC]
GOAL

The fund seeks to provide high total return from a broadly diversified
portfolio of equity securities.

[GRAPHIC]
INVESTMENT APPROACH

The fund invests primarily in large- and medium-capitalization U.S. companies.
Industry by industry, the fund's weightings are similar to those of the Standard
& Poor's 500 Stock Index (S&P 500). The fund does not look to overweight or
underweight industries.

Within each industry, the fund modestly overweights stocks that are ranked as
undervalued or fairly valued while modestly underweighting or not holding stocks
that appear overvalued. (The process used to rank stocks according to their
relative valuations is described on page 2.) Therefore, the fund tends to own a
larger number of stocks within the S&P 500 than the U.S. Equity Fund.

[GRAPHIC]
POTENTIAL RISKS AND REWARDS

The value of your investment in the fund will fluctuate in response to movements
in the stock market. Fund performance will also depend on the effectiveness of
J.P. Morgan's research and the management team's stock picking decisions.

The fund's securities and their main risks, as well as fund strategies, are
described in more detail on page 18.

POTENTIAL RISK AND RETURN

[CHART]

The positions of the funds in this graph reflect long-term performance goals
only, and are relative, not absolute.

PORTFOLIO MANAGEMENT

The fund's assets are managed by J.P. Morgan, which currently manages over $240
billion, including more than $27 billion using the same strategy as the fund.

The portfolio management team is led by James C. Wiess and Timothy J. Devlin,
both vice presidents, who have been on the team since the fund's inception in
January of 1997. Mr. Wiess has been at J.P. Morgan since 1992, Mr. Devlin since
July of 1996. Prior to managing this fund, Mr. Wiess had been managing
structured equity portfolios and Mr. Devlin was an equity portfolio manager at
Mitchell Hutchins Asset Management Inc.

INVESTOR EXPENSES

The current expenses you should expect to pay as an investor in the fund are
shown at right. The fund has no sales, redemption, exchange, or account fees,
although some institutions may charge you a fee for shares you buy through them.
The annual fund expenses shown are deducted from fund assets prior to
performance calculations.

(1) The fund has a master/feeder structure as described on page 17. This table
shows the fund's expenses and its share of master portfolio expenses for
the past fiscal period, expressed as a percentage of the fund's average net
assets and reflecting reimbursement for ordinary expenses over 0.45%.

(2) Without reimbursement, other expenses and total operating expenses would
have been 0.99% and 1.34%, respectively, on an annualized basis. There is
no guarantee that reimbursement will continue beyond 9/30/98.

(3) The inception date of the Private Account Composite is 10/31/89.

(4) THE PERFORMANCE OF THE PRIVATE ACCOUNT COMPOSITE DOES NOT REPRESENT THE
FUND'S PERFORMANCE AND SHOULD NOT BE INTERPRETED AS INDICATIVE OF THE
FUND'S FUTURE PERFORMANCE. The Composite reflects the historical
performance of discretionary investment management accounts under the
management of the fund's advisor with substantially similar objectives and
policies as the fund. Historical Composite performance information reflects
the deduction of the fund's total expenses of 0.45%. The performance of
accounts in the Composite might have been lower if they were subject to the
extra restrictions imposed on mutual funds. AIMR performance requirements
went into effect 1/1/93 and prior to that date the Composite may not have
included all discretionary accounts.

(5) The S&P 500 Index is an unmanaged index of U.S. stocks widely used as a
measure of overall stock market performance.

(6) The fund commenced operations on 1/3/97 and performance is calculated as of
1/31/97.

GOAL

The fund seeks to provide high total return from a portfolio of selected stocks.

[GRAPHIC]
INVESTMENT APPROACH

The fund invests primarily in large- and medium-capitalization U.S. companies.
Industry by industry, the fund's weightings are similar to those of the Standard
& Poor's 500 Stock Index (S&P 500). The fund can moderately underweight or
overweight industries when it believes it will benefit performance.

Within each industry, the fund focuses on those stocks that are ranked as most
undervalued according to the investment process described on page 2. The fund
generally considers selling stocks that appear overvalued.

[GRAPHIC]
POTENTIAL RISKS AND REWARDS

By emphasizing undervalued stocks, the fund has the potential to produce returns
that exceed those of the S&P 500. At the same time, by controlling the industry
weightings of the fund so they can differ only moderately from the industry
weightings of the S&P 500, the fund seeks to limit its volatility to that of the
overall market, as represented by this index.

The fund's securities and their main risks, as well as fund strategies, are
described in more detail on page 18.

SMALL COMPANY FUND TICKER SYMBOL: JUSSX
- --------------------------------------------------------------------------------
REGISTRANT: J.P. MORGAN INSTITUTIONAL FUNDS
(J.P. MORGAN INSTITUTIONAL U.S. SMALL
COMPANY FUND)

[GRAPHIC]
GOAL

The fund seeks to provide high total return from a portfolio of small company
stocks.

[GRAPHIC]
INVESTMENT APPROACH

The fund invests primarily in small and medium sized U.S. companies whose market
capitalizations are greater than $100 million and less than $3 billion. Industry
by industry, the fund's weightings are similar to those of the Russell 2500
Index. The fund can moderately underweight or overweight industries when it
believes it will benefit performance.

Within each industry, the fund focuses on those stocks that are ranked as most
undervalued according to the process described on page 2. The fund generally
considers selling stocks that appear overvalued or have grown into large-cap
stocks.

[GRAPHIC]
POTENTIAL RISKS AND REWARDS

Small- and medium-cap stocks have historically offered higher long-term growth
than large-cap stocks, and have also involved higher risks. The fund's small-cap
emphasis means it is likely to be more sensitive to economic news and is likely
to fall further in value during broad market downturns. The fund pursues returns
that exceed those of the Russell 2500 Index while seeking to limit its
volatility relative to this index.

The fund's securities and their main risks, as well as fund strategies, are
described in more detail on page 18.

The portfolio management team is led by James B. Otness, managing director, and
Michael J. Kelly, vice president. Mr. Otness began managing the fund in February
of 1993, has managed small-cap U.S. equity portfolios since 1985, and has been
at J.P. Morgan since 1970. Mr. Kelly joined the team in May of 1996, has managed
other U.S. equity portfolios for J.P. Morgan prior to managing this fund, and
has been at J.P. Morgan since 1985.

- --------------------------------------------------------------------------------
REGISTRANT: J.P. MORGAN SERIES TRUST
(J.P. MORGAN TAX AWARE DISCIPLINED EQUITY
FUND: INSTITUTIONAL SHARES)

[GRAPHIC]
GOAL

The fund seeks to provide high total return while being sensitive to the impact
of capital gains taxes on investors' returns.

[GRAPHIC]
INVESTMENT APPROACH

To this investment approach the fund adds the element of tax aware investing.
The fund's tax aware investment strategies are described on page 3.

[GRAPHIC]
POTENTIAL RISKS AND REWARDS

By owning a large number of stocks within the S&P 500, with an emphasis on those
that appear undervalued or fairly valued, and by tracking the industry
weightings of that index, the fund seeks returns that modestly exceed those of
the S&P 500 over the long term with virtually the same level of volatility. The
fund's tax aware strategies may reduce your capital gains but will not eliminate
them. Maximizing after-tax returns may require trade-offs that reduce pre-tax
returns.

The fund's securities and their main risks, as well as fund strategies, are
described in more detail on page 18.

POTENTIAL RISK AND RETURN

[CHART]

The positions of the funds in this graph reflect long-term performance goals
only, and are relative, not absolute.

PORTFOLIO MANAGEMENT

The fund's assets are managed by J.P. Morgan, which currently manages over $240
billion, including more than $27 billion using the same strategy as the fund.

The portfolio management team is led by Robin B. Chance, vice president, and
Frederic A. Nelson, managing director, who have been on the team since the
fund's inception in January of 1997. Ms. Chance has been at J.P. Morgan since
1987, Mr. Nelson since May of 1994. Prior to managing this fund, both were
responsible for structured equity strategies. Prior to joining Morgan, Mr.
Nelson was a portfolio manager at Bankers Trust.

- --------------------------------------------------------------------------------
INVESTOR EXPENSES

The current expenses you should expect to pay as an investor in the fund are
shown at right. The fund has no sales, exchange, or account fees, although some
institutions may charge you a fee for shares you buy through them. The fund's
redemption fee is paid out of the proceeds you receive when you sell applicable
shares; this fee does not apply to in-kind redemptions. The annual fund expenses
shown are deducted from fund assets prior to performance calculations.

Footnotes for this section are shown on next page.

assumes that you continued to hold your shares, the second that you sold all
shares for cash at the end of each time period. The example is for comparison
only; the fund's actual return and expenses will be different.

YOUR INVESTMENT
- --------------------------------------------------------------------------------

he or she is prepared to handle your planning and transaction needs. Your
financial professional will be able to assist you in establishing your fund
account, executing transactions, and monitoring your investment. If your fund
investment is not held in the name of your financial professional and you prefer
to place a transaction order yourself, please use the instructions for investing
directly.

INVESTING THROUGH AN EMPLOYER-SPONSORED RETIREMENT PLAN

Your fund investments are handled through your plan. Refer to your plan
materials or contact your benefits office for information on buying, selling, or

Tax Aware funds and for additional investments $25,000, although these
minimums may be less for some investors. For more information on minimum

ACCOUNT AND TRANSACTION POLICIES

TELEPHONE ORDERS The funds accept telephone orders from all shareholders. To
guard against fraud, the funds require shareholders to use a PIN, and may record
telephone orders or take other reasonable precautions. However, if a fund does
take such steps to ensure the authenticity of an order, you may bear any loss if
the order later proves fraudulent.

EXCHANGES With the exception of the Tax Aware Fund, you may exchange shares in
these funds for shares in any other J.P. Morgan Institutional or J.P. Morgan
mutual fund at no charge (subject to the securities laws of your state). When
making exchanges, it is important to observe any applicable minimums. Keep in
mind that for tax purposes an exchange is considered a sale.

A fund may alter, limit, or suspend its exchange policy at any time.

BUSINESS HOURS AND NAV CALCULATIONS The funds' regular business days and hours
are the same as those of the New York Stock Exchange. Each fund calculates its
net asset value per share (NAV) every business day at 4:15 p.m. eastern time.

TIMING OF ORDERS Orders to buy or sell shares are executed at the next NAV
calculated after the order has been accepted. Orders are accepted until 4:00
p.m. eastern time every business day and are executed the same day, at that
day's NAV. A fund has the right to suspend redemption of shares and to postpone
payment of proceeds for up to seven days or as permitted by law.

YOUR INVESTMENT 15

<PAGE>

TIMING OF SETTLEMENTS When you buy shares, you will become the owner of record
when a fund receives your payment, generally the day following execution. When
you sell shares, cash proceeds are generally available the day following
execution and will be forwarded according to your instructions. In-kind
redemptions (described on page 3) will be available as promptly as is feasible.

When you sell shares that you recently purchased by check, your order will be
executed at the next NAV but the proceeds will not be available until your check
clears. This may take up to 15 days.

STATEMENTS AND REPORTS The funds send monthly account statements as well as
confirmations after each purchase or sale of shares (except reinvestments).
Every six months each fund sends out an annual or semi-annual report, containing
information on its holdings and a discussion of recent and anticipated market
conditions and fund performance.

ACCOUNTS WITH BELOW-MINIMUM BALANCES If your account balance falls below the
minimum for 30 days as a result of selling shares (and not because of
performance), a fund may request that you buy more shares or close your account.
If your account balance is still below the minimum 60 days after notification, a
fund may close out your account and send the proceeds to the address of record.

DIVIDENDS AND DISTRIBUTIONS

Income dividends are typically paid four times a year for the Disciplined
Equity, U.S. Equity and Tax Aware funds; and twice a year for the U.S. Small
Company Fund. Each fund typically makes capital gains distributions, if any,
once per year. However, a fund may make more or fewer payments in a given year,
depending on its investment results and its tax compliance situation. Each
fund's dividends and distributions consist of most or all of its net investment
income and net realized capital gains.

Dividends and distributions are reinvested in additional fund shares.
Alternatively, you may instruct your financial professional or J.P. Morgan Funds
Services to have them sent to you by check, credited to a separate account, or
invested in another J.P. Morgan Institutional fund.

TAX CONSIDERATIONS

In general, selling shares for cash, exchanging shares, and receiving
distributions (whether reinvested or taken in cash) are all taxable events.
These transactions typically create the following tax liabilities:

TRANSACTION TAX STATUS
- --------------------------------------------------------------------------------
Income dividends Ordinary income
- --------------------------------------------------------------------------------
Short-term capital gains Ordinary income
distributions
- --------------------------------------------------------------------------------
Long-term capital gains Capital gains
distributions
- --------------------------------------------------------------------------------
Sales or exchanges of shares Capital gains or losses
owned for more than one year
- --------------------------------------------------------------------------------
Sales or exchanges of shares Gains are treated as ordinary
owned for one year or less income; losses are subject
to special rules
- --------------------------------------------------------------------------------

Because long-term capital gains distributions are taxable as capital gains
regardless of how long you have owned your shares, you may want to avoid making
a substantial investment when a fund is about to declare a long-term capital
gains distribution.

Every January, each fund issues tax information on its distributions for the
previous year.

Any investor for whom a fund does not have a valid taxpayer identification
number will be subject to backup withholding for taxes.

The tax considerations described in this section do not apply to tax-deferred
accounts or other non-taxable entities.

Because each investor's tax circumstances are unique, please consult your tax
professional about your fund investment.

FUND DETAILS
- --------------------------------------------------------------------------------

BUSINESS STRUCTURE

As noted earlier, each fund (except the Tax Aware Fund) is a "feeder" fund that
invests in a master portfolio. (Except where indicated, this prospectus uses the
term "the fund" to mean the feeder fund and its master portfolio taken
together.)

Each master portfolio accepts investments from other feeder funds, and all the
feeders of a given master portfolio bear the portfolio's expenses in proportion
to their assets. However, each feeder can set its own transaction minimums,
fund-specific expenses, and other conditions. This means that one feeder could
offer access to the same master portfolio on more attractive terms, or could
experience better performance, than another feeder. Information about other
feeders is available by calling 1-800-766-7722. Generally, when a master
portfolio seeks a vote, its feeder fund will hold a shareholder meeting and cast
its vote proportionately, as instructed by its shareholders. Fund shareholders
(except Tax Aware Fund shareholders) are entitled to one vote per fund share.
Tax Aware Fund shareholders are entitled to one full or fractional vote for each
dollar or fraction of a dollar invested.

The Tax Aware Fund is a series of J.P. Morgan Series Trust, a Massachusetts
business trust. The Tax Aware Fund is one of three series of shares currently
offered by the trust. Information about other series or classes is available by
calling 1-800-766-7722. In the future, the trustees could create other series or
share classes, which would have different expenses.

MANAGEMENT AND ADMINISTRATION

The feeder funds described in this prospectus, their corresponding master
portfolios, and J.P. Morgan Series Trust, are all governed by the same trustees.
The trustees are responsible for overseeing all business activities. The
trustees are assisted by Pierpont Group, Inc., which they own and operate on a
cost basis; costs are shared by all funds governed by these trustees. Funds
Distributor, Inc., as co-administrator, provides fund officers. J.P. Morgan, as
co-administrator, oversees each fund's other service providers.

J.P. Morgan, subject to the expense reimbursements described earlier in this
prospectus, receives the following fees for investment advisory and other
services:

- --------------------------------------------------------------------------------
ADVISORY SERVICES PERCENTAGE OF THE MASTER

this prospectus, pays J.P. Morgan the following fees for investment advisory and
other services:
