J.P. MORGAN PRIME MONEY MARKET
RESERVES FUND
- --------------------------------------------------------------------------------

                                  REGISTRANT: J.P. MORGAN INSTITUTIONAL FUNDS
                                  (J.P. MORGAN PRIME MONEY MARKET RESERVES FUND)

[GRAPHIC] GOAL

      The fund's goal is to maximize current income consistent with the
preservation of capital and same-day liquidity. This goal can be changed without
shareholder approval.

[GRAPHIC] INVESTMENT APPROACH

      Principal Strategies

The fund looks for investments across a broad spectrum of U.S.
dollar-denominated money market securities, typically emphasizing different
types of securities at different times in order to take advantage of changing
yield differentials. The fund's investments may include obligations issued by
the U.S. Treasury, government agencies, domestic and foreign banks and
corporations, foreign governments, repurchase agreements, reverse repurchase
agreements, as well as asset-backed securities, taxable municipal obligations,
and other money market instruments. Some of these investments may be illiquid or
purchased on a when-issued or delayed delivery basis.

The fund's yield will vary in response to changes in interest rates. How well
the fund's yield compares to the yields of similar money market funds will
depend on the success of the investment process described on page 7.

Principal Risks

As with all money market funds, the fund's investments are subject to various
risks, which, while generally considered to be minimal, could cause its share
price to fall below $1. For example, the issuer or guarantor of a portfolio
security or the counterparty to a contract could default on its obligation. An
unexpected rise in interest rates could also lead to a loss in share price if
the fund is near the maximum allowable dollar weighted average maturity
(currently not to exceed 90 days) at the time. To the extent that the fund
invests in foreign securities, the fund could lose money because of foreign
government actions, political instability, or lack of adequate and accurate
information. Also, the fund may have difficulty valuing its illiquid holdings
and may be unable to sell them at the time or price it desires. While these
possibilities exist, the fund's investment process and management policies are
designed to minimize the likelihood and impact of these risks.

An investment in the fund is not a deposit of any bank and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other government
agency. Although the fund seeks to preserve the value of your investment at $1
per share, it is possible to lose money by investing in the fund.

PORTFOLIO MANAGEMENT


The fund's assets are managed by J.P. Morgan Investment Management Inc., a
subsidiary of J.P. Morgan Chase & Co. J.P. Morgan Chase currently manages
more than $700 billion, including more than $___ billion using similar
strategies as the fund.


The advisor uses a team of portfolio managers and traders to manage the fund.
The portfolio management team is led by John Donohue, vice president, who has
been on the team since joining J.P. Morgan in June of 1997 from Goldman Sachs &
Co., where he was an Institutional Money Market Portfolio Manager; and Mark
Settles, vice president, who has been on the team since November 1999 and has
been at J.P. Morgan since 1994. Prior to managing this fund, Mr. Settles was a
fixed income trader on J.P. Morgan's New York and London trading desks. The
traders on the team are Donald Clemmenson, vice president, who has been on the
team since its inception; Gunter Heiland, associate, who has been on the team
since joining J.P. Morgan in June of 1997 from Salomon Brothers, where he was a
sales assistant; and Kimberly Weil, who has been on the team since its
inception.

The example below is intended to help you compare the cost of investing in the
fund with the cost of investing in other mutual funds. The example assumes:
$10,000 initial investment, 5% return each year, net expenses for the period
3/1/01 through 2/28/02, and total operating expenses thereafter, and all shares
sold at the end of each time period. The example is for comparison only; the
fund's actual return and your actual costs may be higher or lower.

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

(1)   The fund commenced operations on 6/1/99, and returns reflect performance
      of the fund from 1/1/00 forward. For the period from 8/1/93 through
      6/30/99, returns reflect the performance of the J.P. Morgan Prime Money
      Market Fund, a separate feeder fund investing in the same master
      portfolio. For the period from 1/1/91 through 7/31/93, returns reflect the
      performance of The Pierpont Money Market Fund, the predecessor to the J.P.
      Morgan Prime Money Market Fund. These returns reflect lower operating
      expenses than those of the fund. The actual expenses of the J.P. Morgan
      Prime Money Market Fund as of the year end 11/30/00 are 0.44%. Therefore,
      these returns may be lower had it existed during the same period.


(2)   The fund's fiscal year end is 11/30.

(3)   The fund has a master/feeder structure as described on page 10. This table
      shows the fund's expenses and its share of master portfolio expenses for
      the past fiscal period, before reimbursement, expressed as a percentage of
      the fund's average net assets.

(4)   Service organizations (described on page 8) may charge other fees to their
      customers who are the beneficial owners of shares in connection with their
      customers' accounts. Such fees, if any, may affect the return such
      customers realize with respect to their investments.


(5)   Reflects an agreement by Morgan Guaranty Trust Company of New York
      ("Morgan Guaranty"), an affiliate of J.P. Morgan, to reimburse the fund to
      the extent total operating expenses exceed 0.70% (excluding interest,
      taxes and extraordinary expenses) of the fund's average daily net assets
      through 2/28/02.

RESERVES FUND
- --------------------------------------------------------------------------------

                               REGISTRANT: J.P. MORGAN INSTITUTIONAL FUNDS
                               (J.P. MORGAN TREASURY MONEY MARKET RESERVES FUND)

[GRAPHIC] GOAL

      The fund's goal is to provide high current income consistent with the
preservation of capital and same-day liquidity. This goal can be changed without
shareholder approval.

[GRAPHIC] INVESTMENT APPROACH

      Principal Strategies


The fund purchases securities that offer the highest credit quality and provide
regular income. It invests primarily in U.S. Treasury obligations and repurchase
agreements collateralized by these obligations. Some of these investments may be
purchased on a when-issued or delayed delivery basis. The fund may also invest
in certain bank obligations when Treasury obligations or repurchase agreements
are temporarily unavailable to the fund.


The fund's yield will vary in response to changes in interest rates. How well
the fund's yield compares to the yields of similar money market funds will
depend on the success of the investment process described on page 7.

Principal Risks

While the fund's U.S. Treasury obligations are backed by the full faith and
credit of the federal government, investors should bear in mind that any
repurchase agreements the fund may hold do not have this guarantee (even though
they are fully collateralized by Treasuries), and that in any case, government
guarantees do not extend to shares of the fund itself.

The portion of the fund's income derived from direct investments in U.S.
Treasury obligations may be exempt from state and local personal income taxes.

An investment in the fund is not a deposit of any bank and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other government
agency. Although the fund seeks to preserve the value of your investment at $1
per share, it is possible to lose money by investing in the fund.

PORTFOLIO MANAGEMENT


The fund's assets are managed by J.P. Morgan Investment Management Inc., a
subsidiary of J.P. Morgan Chase & Co. J.P. Morgan Chase currently manages

(1)   The fund commenced operations on 6/1/99, and returns reflect performance
      of the fund from 7/1/99 forward. For the period 7/7/97 through 6/31/99,
      returns reflect the performance of the J.P. Morgan Institutional Service
      Treasury Money Market Fund. The returns of this predecessor fund reflect
      lower operating expenses than those of the fund. Therefore, these returns

MONEY MARKET MANAGEMENT APPROACH
- --------------------------------------------------------------------------------

J.P. MORGAN


Known for its commitment to proprietary research and its disciplined investment
strategies, J.P. Morgan Chase is the asset management choice for many of the
world's most respected corporations, financial institutions, governments, and
individuals. Today, J.P. Morgan Chase employs approximately ___ research
analysts, capital market researchers, portfolio managers and traders around the
world and has more than $700 billion in assets under management, including
assets managed by the funds' advisor, J.P. Morgan Investment Management Inc.


J.P. MORGAN MONEY MARKET RESERVES FUNDS

Each of these funds invests in high-quality short-term debt securities by
investing through a master portfolio (another fund with the same goal). Each
fund accrues dividends daily, pays them to shareholders monthly, and seeks to
maintain a stable $1 share price.

THE SPECTRUM OF MONEY MARKET RESERVES FUNDS

The funds described in this prospectus differ primarily in the types of
securities they hold and in the tax status of the income they offer. The table
below provides an overview of the main types of securities in which each fund
may invest. The distinguishing features of each money market fund are described
in more detail on the preceding pages.

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

Who May Want to Invest

The funds are designed for investors who:

o     want an investment that strives to preserve capital

o     want regular income from a high quality portfolio

o     want a highly liquid investment

o     are looking for an interim investment

o     are pursuing a short-term goal

The funds are not designed for investors who:

o     are investing for long-term growth

o     are investing for high income

o     require the added security of the FDIC insurance

Money Market Funds and Stability

Money market funds are subject to a range of federal regulations designed to
promote stability. For example, money market funds must maintain a weighted
average maturity of no more than 90 days, and generally may not invest in any
securities with a remaining maturity of more than 13 months. Keeping the
weighted average maturity this short helps funds in their pursuit of a stable $1
share price.

6 | MONEY MARKET MANAGEMENT APPROACH


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

MONEY MARKET INVESTMENT PROCESS

While each fund follows its own strategy, the funds as a group share a single
investment philosophy. This philosophy, developed by the funds' advisor,
emphasizes investment quality through in-depth research of short-term securities
and their issuers. This allows each fund to focus on providing current income
without compromising share price stability.

In researching short-term securities, J.P. Morgan's credit analysts enhance the
data furnished by rating agencies by drawing on the insights of J.P. Morgan's
fixed income trading specialists and equity analysts. Only securities highly
rated by independent rating agencies as well as J.P. Morgan's proprietary
ratings system are considered for investment.

In managing the funds described in this prospectus, J.P. Morgan employs a
three-step process that combines maturity determination, sector allocation and
fundamental research for identifying portfolio securities:

[GRAPHIC]
J.P. Morgan uses a disciplined process to
control each fund's sensitivity
to interest rates

Maturity determination Based on analysis of a range of factors, including
current yields, economic forecasts, and anticipated fiscal and monetary
policies, J.P. Morgan establishes the desired dollar weighted average maturity
for each fund within the permissible 90-day range. Controlling weighted average
maturity allows the funds to manage risk, since securities with shorter
maturities are typically less sensitive to interest rate shifts than those with
longer maturities.

[GRAPHIC]
The funds invest across different
sectors for diversification and to
take advantage of yield spreads

Sector allocation Analysis of the yields available in different sectors of the
short-term debt market allows J.P. Morgan to adjust each fund's sector
allocation, with the goal of enhancing current income while also maintaining
diversification across permissible sectors.

[GRAPHIC]
Each fund selects its securities as
described earlier in this prospectus

Security selection Based on the results of the firm's credit research and each
fund's maturity determination and sector allocation, the portfolio managers and
dedicated fixed-income traders make buy and sell decisions according to each
fund's goal and strategy.

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

INVESTING THROUGH A SERVICE ORGANIZATION

Prospective investors may only purchase shares of each fund with the assistance
of a service organization. Your service organization is paid by the fund to
assist you in establishing your fund account, executing transactions, and
monitoring your investment. The minimum amount for initial investments in a fund
by a service organization is $10,000,000 and for additional investments $25,000,
although these minimums may be less for some investors. Service organizations
may provide the following services in connection with their customers'
investments in the funds:

o     Acting, directly or through an agent, as the sole shareholder of record

o     Maintaining account records for customers

o     Processing orders to purchase, redeem or exchange shares for customers

o     Responding to inquiries from shareholders

o     Assisting customers with investment procedures

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 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 days and NAV calculations The funds' regular business days are the same
as those of the New York Stock Exchange. The Prime and Treasury Money Market
Funds calculate their net asset value per share (NAV) every business day at 5:00
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. Purchase and redemption orders for
each fund must be received by the time NAV is calculated for that fund. For the
purchase to be effective and dividends to be earned on the same day, immediately
available funds must be received by 5:00 p.m. eastern time for Prime and
Treasury Money Market Funds on a fund business day. A fund has the right to
suspend redemption of shares as permitted by law and to postpone payment of
proceeds for up to seven days.


Timing of settlements When you buy shares, you will become the owner of record
when a fund receives your payment.

Redemption orders for each fund received by the respective cut-off times will be
paid in immediately available funds, normally on the same day, according to
instructions on file.

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), the fund reserves the right to request that you buy more shares or
close your account. If your account balance is still below the minimum 60 days
after notification, the fund reserves the right to close out your account and
send the proceeds to the address of record.

DIVIDENDS AND DISTRIBUTIONS

Substantially all income dividends are declared daily and paid monthly. If all
of an investor's shares are redeemed during the month, accrued but unpaid
dividends are paid with the redemption proceeds. Shares of the funds earn
dividends on the business day their purchase is effective, but not on the
business day their redemption is effective.

Dividends and distributions are reinvested in additional fund shares.
Alternatively, you may instruct your financial professional to have them sent to
you by check.

TAX CONSIDERATIONS

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

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

Transaction                        Tax status

Income dividends                   Ordinary income

Short-term capital gains           Ordinary income
distributions

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

MASTER/FEEDER STRUCTURE

As noted earlier, each fund is a series of J.P. Morgan Institutional Funds, a
Massachusetts business trust, and 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
are entitled to one full or fractional vote for each dollar or fraction of a
dollar invested.

Each feeder fund and its master portfolio expect to maintain consistent goals,
but if they do not, the feeder fund will withdraw from the master portfolio,
receiving its assets either in cash or securities. Each feeder fund's trustees
would then consider whether the feeder fund should hire its own investment
adviser, invest in a different master portfolio, or take other action.

MANAGEMENT AND ADMINISTRATION

The feeder funds described in this prospectus and their corresponding master
portfolios 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,
along with J.P. Morgan, provides fund officers. J.P. Morgan, as
co-administrator, oversees each fund's other service providers.

J.P. Morgan receives the following fees for investment advisory and other
services:

Advisory services                  0.20% of the first $1 billion of
                                   each master portfolio's average
                                   net assets plus 0.10% over
                                   $1 billion

Administrative services            Master portfolio's and fund's
(fee shared with Funds             pro-rata portions of 0.09% of
Distributor, Inc.)                 the first $7 billion of average
                                   net assets in J.P. Morgan-
                                   advised portfolios, plus 0.04%
                                   over $7 billion

Shareholder services               0.05% of each fund's
                                   average net assets

Each fund has a service plan which allows it to pay service organizations up to
0.25% of the average net assets of the shares held in the name of the service
organization.

Each fund has adopted a plan under Rule 12b-1 that allows the fund to pay
distribution fees up to 0.25% of each fund's average net assets for the sale and
distribution of its shares. Because these fees are paid out of the fund's assets
on an on-going basis, over time these fees will increase the cost of your
investment and may cost you more than paying other types of sales charges.

J.P. Morgan may also pay fees to certain firms and professionals for providing
recordkeeping or other services in connection with investments in a fund.

FINANCIAL HIGHLIGHTS

The financial tables are intended to help you understand each fund's financial
performance for the past two fiscal periods. Certain information reflects
financial results for a single fund share. The total returns in the tables
represent the rate that an investor would have earned (or lost) on an investment
in a fund (assuming reinvestment of all dividends and distributions). This
information has been audited by PricewaterhouseCoopers LLP, whose reports, along
with each fund's financial statements, are included in the respective fund's
annual report, which are available upon request.
