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

[GRAPHIC OMITTED] 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 OMITTED] INVESTMENT APPROACH
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.

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.

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

PORTFOLIO MANAGEMENT
The fund's assets are managed by J.P. Morgan, which currently manages
approximately $320 billion, including more than $16.9 billion using similar
strategies as the fund.

The portfolio management team is led by Robert R. Johnson, vice president, who
has been on the team since the fund's inception and has been at J.P. Morgan
since 1988, Daniel B. Mulvey, vice president, who joined the team in January of
1995 and has been at J.P. Morgan since 1991, and by John Donohue, vice
president, who has been on the team since joining J.P. Morgan in June of 1997.
Prior to managing this fund, Mr. Donohue was an Institutional Money Market
Portfolio Manager at Goldman Sachs & Co.

PERFORMANCE (unaudited)
The bar chart and table shown below provide some indication of the risks of
investing in J.P. Morgan Prime Money Market Reserves Fund because returns
reflect performance of the J.P. Morgan Prime Money Market Fund, a separate
feeder fund investing in the same master portfolio.

The bar chart indicates some of the risks by showing changes in the
performance of the J.P. Morgan Prime Money Market Fund's shares from year to
year for each of the last ten calendar years.

The table indicates some of the risks by showing how the J.P. Morgan Prime
Money Market Fund's average annual returns for the past one year, five years and
ten years compared to those of the IBC's First Tier Money Fund Average. This is
an average of all major first tier money fund returns.

J.P. Morgan Prime Money Market Fund's past performance does not necessarily
indicate how the fund will perform in the future.

INVESTOR EXPENSES
The expenses of the fund before reimbursement are shown at right. The fund has
no redemption, exchange, or account fees, although some institutions may charge
you a fee for shares you buy through them. The annual fund expenses after
reimbursement are deducted from fund assets prior to performance calculations.

Expense example
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, total operating expenses
(before reimbursement) unchanged, 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.

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

Your cost($) 81 252
- --------------------------------------------------------------------------------

(1) These returns reflect lower operating expenses than those of the fund.
Therefore, these returns are higher than the fund's would have been 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 estimated expenses and its estimated share of master
portfolio expenses for the current fiscal year, before reimbursement,
expressed as a percentage of the fund's estimated 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) After reimbursement total operating expenses will be 0.70%. This
reimbursement arrangement, which does not include extraordinary expenses, will
continue at least through 2/29/00. After that date it can be changed or
terminated at any time at the option of J.P. Morgan.

REGISTRANT: J.P. MORGAN INSTITUTIONAL FUNDS

[GRAPHIC OMITTED] 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 OMITTED] INVESTMENT APPROACH
The fund purchases securities that offer the highest credit quality and provide
regular income. It invests exclusively 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.

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.

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

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 approximately $320 billion in assets under management,
including assets managed by the funds' advisor, J.P. Morgan Investment
Management Inc.

J.P. MORGAN MONEY MARKET 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.

- ----------
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.

THE SPECTRUM OF MONEY MARKET 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.

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:

[GRAPHIC OMITTED]
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 OMITTED]
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 OMITTED]
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 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 is
$10,000,000 and for additional investments $25,000, although these minimums may
be less for some investors.

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 Treasury Money Market Fund
calculates its net asset value per share (NAV) every business day at 4:30 p.m.
eastern time. The Prime Money Market Fund calculates its 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.

<PAGE>

For the purchase to be effective and dividends to be earned on the same day,
immediately available funds must be received by 4:30 p.m. for Treasury Money
Market Fund and by 5:00 p.m. for Prime Money Market Fund eastern time on a fund
business day. 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.

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.

8 YOUR INVESTMENT

<PAGE>

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

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.

MASTER/FEEDER STRUCTURE

As noted earlier, each fund is a series of J.P. Morgan Institutional Funds, a
Massachussetts 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 fund will withdraw from the master portfolio, receiving
its assets either in cash or securities. Each fund's trustees would then
consider whether the 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:

<PAGE>

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 pro-
(fee shared with Funds rata portions of 0.09% of the
Distributor, Inc.) 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.

Year 2000 Fund operations and shareholders could be adversely affected if
the computer systems used by J.P. Morgan, the funds' other service providers and
other entities with computer systems linked to the funds do not properly process
and calculate the date January 1, 2000 and dates thereafter. J.P. Morgan is
working to avoid these problems and to obtain assurances from other service
providers that they are taking similar steps. However, it is not certain that
these actions will be sufficient to prevent these problems from adversely
impacting fund operations and shareholders. In addition, to the extent that
operations of issuers of securities held by the funds are impaired by
date-related problems or prices of securities decline as a result of real or
perceived date-related problems of issuers held by the funds or generally, the
net asset value of the fund will decline.

GENERAL

This Statement of Additional Information relates only to the J.P. Morgan Prime
Money Market Reserves Fund and the J.P. Morgan Treasury Money Market Reserves
Fund (each, a "Fund" and collectively, the "Funds"). Each Fund is a series of
shares of beneficial interest of the J.P. Morgan Institutional Funds, an
open-end management investment company formed as a Massachusetts business trust
(the "Trust"). In addition to the Funds, the Trust consists of other series
representing separate investment funds (each a "J.P. Morgan Institutional
Fund"). The other J.P. Morgan Institutional Funds are covered by separate
Statements of Additional Information.

This Statement of Additional Information describes the financial
history, investment objective and policies, management and operation of each of
the Funds and provides additional information with respect to the Funds and
should be read in conjunction with the relevant Fund's current Prospectus (the
"Prospectus"). Capitalized terms not otherwise defined herein have the meanings
accorded to them in the Prospectus. The Trust's executive offices are located at
60 State Street, Suite 1300, Boston, Massachusetts 02109.

Unlike other mutual funds which directly acquire and manage their own
portfolio of securities, each Fund seeks to achieve its investment objective by
investing all of its investable assets in a corresponding Master Portfolio (the
"Portfolio"), a corresponding open-end management investment company having the
same investment objective as the Fund. Each Fund invests in a Portfolio through
a two-tier master-feeder investment fund structure. See "Special Information
Concerning Investment Structure."

Each Portfolio is advised by J.P. Morgan Investment Management Inc.
("JPMIM" or the "Advisor").

Investments in a Fund are not deposits or obligations of, or guaranteed
or endorsed by, Morgan Guaranty Trust Company of New York, ("Morgan"), an
affiliate of the Advisor, or any other bank. Shares of a Fund are not federally
insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board,
or any other governmental agency. An investment in a Fund is subject to risk
that may cause the value of the investment to fluctuate, and when the investment
is redeemed, the value may be higher or lower than the amount originally
invested by the investor.

INVESTMENT OBJECTIVES AND POLICIES

The following discussion supplements the information regarding the
investment objective of each Fund and the policies to be employed to achieve the
objective by each Portfolio as set forth herein and in the applicable
Prospectus. Since the investment characteristics and experiences of each Fund
correspond directly with those of its corresponding Portfolio, the discussion in
this Statement of Additional Information focuses on the investments and
investment policies of each Portfolio. Accordingly, references below to a
Portfolio also include the corresponding Fund; similarly, references to a Fund
also include the corresponding Portfolio unless the context requires otherwise.

J.P. Morgan Prime Money Market Reserves Fund (the "Prime Money Market
Fund") is designed for investors who seek high current income consistent with
the preservation of capital and same-day liquidity from a portfolio of high
quality money market instruments. The Prime Money Market Fund's investment
objective is to maximize current income consistent with the preservation of
capital and same-day liquidity. The Prime Money Market Fund attempts to achieve
this objective by investing all of its investable assets in The Prime Money
Market Portfolio (the "Portfolio"), a diversified open-end management investment
company having the same investment objective as the Prime Money Market Fund.

The Portfolio seeks to achieve its investment objective by maintaining
a dollar-weighted average portfolio maturity of not more than 90 days and by
investing in U.S. dollar denominated securities described in this Statement of
Additional Information that meet certain rating criteria, present minimal credit
risk and have effective maturities of not more than thirteen months. The
Portfolio's ability to achieve maximum current income is affected by its high
quality standards. See "Quality and Diversification Requirements."

J.P. Morgan Treasury Money Market Reserves Fund (the "Treasury Money
Market Fund") is designed for investors who seek high current income consistent
with the preservation of capital and same-day liquidity from a portfolio of high
quality money market instruments. The Treasury Money Market Fund's investment
objective is to provide current income, consistent with the preservation of
capital and same-day liquidity. The Treasury Money Market Fund attempts to
accomplish this objective by investing all of its investable assets in The
Treasury Money Market Portfolio (the "Portfolio"), a diversified open-end
management investment company having the same investment objective as the
Treasury Money Market Fund.

The Portfolio attempts to achieve its investment objective by
maintaining a dollar-weighted average portfolio maturity of not more than 90
days and by investing in U.S. Treasury securities and related repurchase
agreement transactions as described in this Statement of Additional Information
that have effective maturities of not more than thirteen months. See "Quality
and Diversification Requirements."

Money Market Instruments

A description of the various types of money market instruments that may be
purchased by the Funds appears below. Also see "Quality and Diversification
Requirements."

U.S. Treasury Securities. Each of the Funds may invest in direct
obligations of the U.S. Treasury, including Treasury bills, notes and bonds, all
of which are backed as to principal and interest payments by the full faith and
credit of the United States.

Additional U.S. Government Obligations. The Prime Money Market Fund may
invest in obligations issued or guaranteed by U.S. Government agencies or
instrumentalities. These obligations may or may not be backed by the "full faith
and credit" of the United States. Securities which are backed by the full faith
and credit of the United States include obligations of the Government National
Mortgage Association, the Farmers Home Administration, and the Export-Import
Bank. In the case of securities not backed by the full faith and credit of the
United States, each Fund must look principally to the federal agency 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 commitments. Securities in which each Fund may
invest that are not backed by the full faith and credit of the United States
include, but are not limited to: (i) obligations of the Tennessee Valley
Authority, the Federal Home Loan Mortgage Corporation, the Federal Home Loan
Banks and the U.S. Postal Service, each of which has the right to borrow from
the U.S. Treasury to meet its obligations; (ii) securities issued by the Federal
National Mortgage Association, which are supported by the discretionary
authority of the U.S. Government to purchase the agency's obligations; and (iii)
obligations of the Federal Farm Credit System and the Student Loan Marketing
Association, each of whose obligations may be satisfied only by the individual
credits of the issuing agency.

Foreign Government Obligations. The Prime Money Market Fund, subject to
its applicable investment policies, may also invest in short-term obligations of
foreign sovereign governments or of their agencies, instrumentalities,
authorities or political subdivisions. See "Foreign Investments." These
securities must be denominated in the U.S. dollar.

Bank Obligations. The Prime Money Market Fund, unless otherwise noted
in the Prospectus or below, may invest in negotiable certificates of deposit,
time deposits and bankers' acceptances of (i) banks, savings and loan
associations and savings banks which have more than $2 billion in total assets
and are organized under the laws of the United States or any state, (ii) foreign
branches of these banks or of foreign banks of equivalent size (Euros) and (iii)
U.S. branches of foreign banks of equivalent size (Yankees). The Prime Money
Market Fund will not invest in obligations for which the Advisor, or any of its
affiliated persons, is the ultimate obligor or accepting bank. The Prime Money
Market Fund may also invest in obligations of international banking institutions
designated or supported by national governments to promote economic
reconstruction, development or trade between nations (e.g., the European
Investment Bank, the Inter-American Development Bank, or the World Bank).

Commercial Paper. The Prime Money Market Fund may invest in commercial
paper, including master demand obligations. Master demand obligations are
obligations that provide for a periodic adjustment in the interest rate paid and
permit daily changes in the amount borrowed. Master demand obligations are
governed by agreements between the issuer and Morgan acting as agent, for no
additional fee. The monies loaned to the borrower come from accounts managed by
Morgan or its affiliates, pursuant to arrangements with such accounts. Interest
and principal payments are credited to such accounts. Morgan, an affiliate of
the Advisor, has the right to increase or decrease the amount provided to the
borrower under an obligation. The borrower has the right to pay without penalty
all or any part of the principal amount then outstanding on an obligation
together with interest to the date of payment. Since these obligations typically
provide that the interest rate is tied to the Federal Reserve commercial paper
composite rate, the rate on master demand obligations is subject to change.
Repayment of a master demand obligation to participating accounts depends on the
ability of the borrower to pay the accrued interest and principal of the
obligation on demand which is continuously monitored by Morgan. Since master
demand obligations typically are not rated by credit rating agencies, the Prime
Money Market Fund may invest in such unrated obligations only if at the time of
an investment the obligation is determined by the Advisor to have a credit
quality which satisfies the Prime Money Market Fund's quality restrictions. See
"Quality and Diversification Requirements." Although there is no secondary
market for master demand obligations, such obligations are considered by the
Prime Money Market Fund to be liquid because they are payable upon demand. The
Prime Money Market Fund does not have any specific percentage limitation on
investments in master demand obligations. It is possible that the issuer of a
master demand obligation could be a client of Morgan to whom Morgan, in its
capacity as a commercial bank, has made a loan.

Asset-backed Securities. The Prime Money Market Fund may also invest in
securities generally referred to as asset-backed securities, which directly or
indirectly represent a participation interest in, or are secured by and payable
from, a stream of payments generated by particular assets, such as motor vehicle
or credit card receivables or other asset-backed securities collateralized by
such assets. Asset-backed securities provide periodic payments that generally
consist of both interest and principle payments. Consequently, the life of an
asset-backed security varies with the prepayment experience of the underlying
obligations. Payments of principal and interest may be guaranteed up to certain
amounts and for a certain time period by a letter of credit issued by a
financial institution unaffiliated with the entities issuing the securities. The
asset-backed securities in which a Fund may invest are subject to the Fund's
overall credit requirements. However, asset-backed securities, in general, are
subject to certain risks. Most of these risks are related to limited interests
in applicable collateral. For example, credit card debt receivables are
generally unsecured and the debtors are entitled to the protection of a number
of state and federal consumer credit laws, many of which give such debtors the
right to set off certain amounts on credit card debt thereby reducing the
balance due. Additionally, if the letter of credit is exhausted, holders of
asset-backed securities may also experience delays in payments or losses if the
full amounts due on underlying sales contracts are not realized. Because
asset-backed securities are relatively new, the market experience in these
securities is limited and the market's ability to sustain liquidity through all
phases of the market cycle has not been tested.

Repurchase Agreements. Each of the Funds may enter into repurchase
agreements with brokers, dealers or banks that meet the credit guidelines
approved by the Funds' Trustees. In a repurchase agreement, a Fund buys a
security from a seller that has agreed to repurchase the same security at a
mutually agreed upon date and price. The resale price normally is in excess of
the purchase price, reflecting an agreed upon interest rate. This interest rate
is effective for the period of time the Fund is invested in the agreement and is
not related to the coupon rate on the underlying security. A repurchase
agreement may also be viewed as a fully collateralized loan of money by a Fund
to the seller. The period of these repurchase agreements will usually be short,
from overnight to one week, and at no time will any Fund invest in repurchase
agreements for more than thirteen months. The securities which are subject to
repurchase agreements, however, may have maturity dates in excess of thirteen
months from the effective date of the repurchase agreement. The Treasury Money
Market Fund will only enter into repurchase agreements involving U.S. Treasury
securities. The Funds will always receive securities as collateral whose market
value is, and during the entire term of the agreement remains, at least equal to
100% of the dollar amount invested by the Funds in each agreement plus accrued
interest, and the Funds will make payment for such securities only upon physical
delivery or upon evidence of book entry transfer to the account of the
Custodian. Each Fund will be fully collateralized within the meaning of
paragraph (a)(4) of Rule 2a-7 under the Investment Company Act of 1940, as
amended (the "1940 Act"). If the seller defaults, a Fund might incur a loss if
the value of the collateral securing the repurchase agreement declines and might
incur disposition costs in connection with liquidating the collateral. In
addition, if bankruptcy proceedings are commenced with respect to the seller of
the security, realization upon disposal of the collateral by a Fund may be
delayed or limited.

The Prime Money Market Fund may make investments in other debt
securities with remaining effective maturities of not more than thirteen months,
including, without limitation, corporate and foreign bonds and other obligations
described in the Prospectus or this Statement of Additional Information.

Foreign Investments

The Prime Money Market Fund may invest in certain foreign securities.
All investments must be U.S. dollar-denominated. Investment in securities of
foreign issuers and in obligations of foreign branches of domestic banks
involves somewhat different investment risks from those affecting securities of
U.S. domestic issuers. There may be limited publicly available information with
respect to foreign issuers, and foreign issuers are not generally subject to
uniform accounting, auditing and financial standards and requirements comparable
to those applicable to domestic companies. Any foreign commercial paper must not
be subject to foreign withholding tax at the time of purchase.

Investors should realize that the value of the Fund's investments in
foreign securities may be adversely affected by changes in political or social
conditions, diplomatic relations, confiscatory taxation, expropriation,
nationalization, limitation on the removal of funds or assets, or imposition of
(or change in) exchange control or tax regulations in those foreign countries.
In addition, changes in government administrations or economic or monetary
policies in the United States or abroad could result in appreciation or
depreciation of portfolio securities and could favorably or unfavorably affect
the Fund's operations. Furthermore, the economies of individual foreign nations
may differ from the U.S. economy, whether favorably or unfavorably, in areas
such as growth of gross national product, rate of inflation, capital
reinvestment, resource self-sufficiency and balance of payments position; it may
also be more difficult to obtain and enforce a judgment against a foreign
issuer. Any foreign investments made by the Fund must be made in compliance with
U.S. and foreign currency restrictions and tax laws restricting the amounts and
types of foreign investments.

Additional Investments

Municipal Bonds. The Prime Money Market Fund may invest in municipal
bonds issued by or on behalf of states, territories and possessions of the
United States and the District of Columbia and their Political subdivisions,
agencies, authorities and instrumentalities. The Prime Money Market Fund may
also invest in municipal notes of various types, including notes issued in
anticipation of receipt of taxes, the proceeds of the sale of bonds, other
revenues or grant proceeds, as well as municipal commercial paper and municipal
demand obligations such as variable rate demand notes and master demand
obligations. These municipal bonds and notes will be taxable securities; income
generated from these investments will be subject to federal, state and local
taxes.

When-Issued and Delayed Delivery Securities. Each of the Funds may
purchase securities on a when-issued or delayed delivery basis. For example,
delivery of and payment for these securities can take place a month or more
after the date of the purchase commitment. The purchase price and the interest
rate payable, if any, on the securities are fixed on the purchase commitment
date or at the time the settlement date is fixed. The value of such securities
is subject to market fluctuation and for money market instruments and other
fixed income securities, no interest accrues to a Fund until settlement takes
place. At the time a Fund makes the commitment to purchase securities on a
when-issued or delayed delivery basis, it will record the transaction, reflect
the value each day of such securities in determining its net asset value and, if
applicable, calculate the maturity for the purposes of average maturity from
that date. At the time of settlement a when-issued security may be valued at
less than the purchase price. To facilitate such acquisitions, each Fund will
maintain with the Custodian a segregated account with liquid assets, consisting
of cash, U.S. Government securities or other appropriate securities, in an
amount at least equal to such commitments. On delivery dates for such
transactions, each Fund will meet its obligations from maturities or sales of
the securities held in the segregated account and/or from cash flow. If a Fund
chooses to dispose of the right to acquire a when-issued security prior to its
acquisition, it could, as with the disposition of any other portfolio
obligation, incur a gain or loss due to market fluctuation. Also, a Fund may be
disadvantaged if the other party to the transactions defaults. It is the current
policy of each Fund (except the Treasury Money Market Fund) not to enter into
when-issued commitments exceeding in the aggregate 15% of the market value of a
Fund's total assets, less liabilities other than the obligations created by
when-issued commitments.

Investment Company Securities. Securities of other investment companies
may be acquired by each of the Funds and their corresponding Portfolios to the
extent permitted under the 1940 Act or any order pursuant thereto. These limits
currently require that, as determined immediately after a purchase is made, (i)
not more than 5% of the value of a Fund's total assets will be invested in the
securities of any one investment company, (ii) not more than 10% of the value of
its total assets will be invested in the aggregate in securities of investment
companies as a group, and (iii) not more than 3% of the outstanding voting stock
of any one investment company will be owned by a Fund, provided however, that a
Fund may invest all of its investable assets in an open-end investment company
that has the same investment objective as the Fund (its corresponding
Portfolio). As a shareholder of another investment company, a Fund or Portfolio
would bear, along with other shareholders, its pro rata portion of the other
investment company's expenses, including advisory fees. These expenses would be
in addition to the advisory and other expenses that a Fund or Portfolio bears
directly in connection with its own operations.

Reverse Repurchase Agreements. Each of the Funds may enter into reverse
repurchase agreements. In a reverse repurchase agreement, a Fund sells a
security and agrees to repurchase the same security at a mutually agreed upon
date and price reflecting the interest rate effective for the term of the
agreement. For purposes of the 1940 Act a reverse repurchase agreement is also
considered as the borrowing of money by the Fund and, therefore, a form of
leverage. Leverage may cause any gains or losses for a Fund to be magnified. The
Funds will invest the proceeds of borrowings under reverse repurchase
agreements. In addition, except for liquidity purposes, a Fund will enter into a
reverse repurchase agreement only when the expected return from the investment
of the proceeds is greater than the expense of the transaction. A Fund will not
invest the proceeds of a reverse repurchase agreement for a period which exceeds
the duration of the reverse repurchase agreement. Each Fund will establish and
maintain with the custodian a separate account with a segregated portfolio of
securities in an amount at least equal to its purchase obligations under its
reverse repurchase agreements. See "Investment Restrictions" for each Fund's
limitations on reverse repurchase agreements and bank borrowings.

Loans of Portfolio Securities. Subject to applicable investment
restrictions, each Fund is permitted to lend its securities in an amount up to
33 1/3% of the value of the Fund's net assets. Each of the Funds may lend its
securities if such loans are secured continuously by cash or equivalent
collateral or by a letter of credit in favor of the Fund at least equal at all
times to 100% of the market value of the securities loaned, plus accrued
interest. While such securities are on loan, the borrower will pay the Fund any
income accruing thereon. Loans will be subject to termination by the Funds in
the normal settlement time, generally three business days after notice, or by
the borrower on one day's notice. Borrowed securities must be returned when the
loan is terminated. Any gain or loss in the market price of the borrowed
securities which occurs during the term of the loan inures to a Fund and its
respective investors. The Funds may pay reasonable finders' and custodial fees
in connection with a loan. In addition, a Fund will consider all facts and
circumstances including the creditworthiness of the borrowing financial
institution, and no Fund will make any loans in excess of one year. The risks to
each Fund with respect to borrowers of its portfolio securities are similar to
the risks to the Funds with respect to sellers in repurchase agreement
transactions. See "Repurchase Agreements". The Funds will not lend their
securities to any officer, Trustee, Director, employee or other affiliate of the
Funds, the Advisor or the Distributor, unless otherwise permitted by applicable
law.

Illiquid Investments, Privately Placed and Certain Unregistered
Securities. The Prime Money Market Fund may invest in privately placed,
restricted, Rule 144A or other unregistered securities. It may not acquire any
illiquid holdings if, as a result thereof, more than 10% of its net assets would
be in illiquid investments. Subject to this fundamental policy limitation, the
Fund may acquire investments that are illiquid or have limited liquidity, such
as private placements or investments that are not registered under the
Securities Act of 1933, as amended (the "1933 Act") and cannot be offered for
public sale in the United States without first being registered under the 1933
Act. An illiquid investment is any investment that cannot be disposed of within
seven days in the normal course of business at approximately the amount at which
it is valued by the Fund. The price the Fund pays for illiquid securities or
receives upon resale may be lower than the price paid or received for similar
securities with a more liquid market. Accordingly the valuation of these
securities will reflect any limitations on their liquidity.

The Prime Money Market Fund may also purchase Rule 144A securities sold
to institutional investors without registration under the 1933 Act. These
securities may be determined to be liquid in accordance with guidelines
established by the Advisor and approved by the Trustees. The Trustees will
monitor the Advisor's implementation of these guidelines on a periodic basis.

As to illiquid investments, a Fund is subject to a risk that should the
Fund decide to sell them when a ready buyer is not available at a price the Fund
deems representative of their value, the value of the Fund's net assets could be
adversely affected. Where an illiquid security must be registered under the 1933
Act, before it may be sold, a Fund may be obligated to pay all or part of the
registration expenses, and a considerable period may elapse between the time of
the decision to sell and the time the Fund may be permitted to sell a security
under an effective registration statement. If, during such a period, adverse
market conditions were to develop, a Fund might obtain a less favorable price
than prevailed when it decided to sell.

Synthetic Instruments. The Prime Money Market Fund may invest in
certain synthetic instruments. Such instruments generally involve the deposit of
asset-backed securities in a trust arrangement and the issuance of certificates
evidencing interests in the trust. The certificates are generally sold in
private placements in reliance on Rule 144A. The Advisor will review the
structure of synthetic instruments to identify credit and liquidity risks and
will monitor those risks. See "Illiquid Investments, Privately Placed and
Certain Unregistered Securities".

Quality and Diversification Requirements

Each of the Funds intends to meet the diversification requirements of
the 1940 Act. Current 1940 Act requirements require that with respect to 75% of
the assets of each Fund are subject to the following fundamental limitations:
(1) the Fund may not invest more than 5% of its total assets in the securities
of any one issuer, except obligations of the U.S. Government, its agencies and
instrumentalities, and (2) the Fund may not own more than 10% of the outstanding
voting securities of any one issuer. As for the other 25% of the Fund's assets
not subject to the limitation described above, there is no limitation on
investment of these assets under the 1940 Act, so that all of such assets may be
invested in securities of any one issuer. Investments not subject to the
limitations described above could involve an increased risk to a Fund should an
issuer, or a state or its related entities, be unable to make interest or
principal payments or should the market value of such securities decline.

At the time any of the Funds invest in any taxable commercial paper,
master demand obligation, bank obligation or repurchase agreement, the issuer
must have outstanding debt rated A or higher by Moody's or Standard & Poor's,
the issuer's parent corporation, if any, must have outstanding commercial paper
rated Prime-1 by Moody's or A-1 by Standard & Poor's, or if no such ratings are
available, the investment must be of comparable quality in Morgan's opinion.

Prime Money Market Fund. In order to maintain a stable net asset value,
the Prime Money Market Fund will (i) limit its investment in the securities
(other than U.S. Government securities) of any one issuer to no more than 5% of
its assets, measured at the time of purchase, except for investments held for
not more than three business days; and (ii) limit investments to securities that
present minimal credit risks and securities (other than U.S. Government
securities) that are rated within the highest short-term rating category by at
least two nationally recognized statistical rating organizations ("NRSROs") or
by the only NRSRO that has rated the security. Securities which originally had a
maturity of over one year are subject to more complicated, but generally similar
rating requirements. A description of illustrative credit ratings is set forth
in "Appendix A." The Fund may also purchase unrated securities that are of
comparable quality to the rated securities described above. Additionally, if the
issuer of a particular security has issued other securities of comparable
priority and security and which have been rated in accordance with (ii) above,
that security will be deemed to have the same rating as such other rated
securities.

In addition, the Board of Trustees has adopted procedures which (i)
require the Board of Trustees to approve or ratify purchases by the Fund of
securities (other than U.S. Government securities) that are unrated; (ii)
require the Fund to maintain a dollar-weighted average portfolio maturity of not
more than 90 days and to invest only in securities with a remaining maturity of
not more than thirteen months; and (iii) require the Fund, in the event of
certain downgradings of or defaults on portfolio holdings, to dispose of the
holding, subject in certain circumstances to a finding by the Trustees that
disposing of the holding would not be in the Fund's best interest.

Treasury Money Market Fund. In order to maintain a stable net asset
value, the Treasury Money Market Fund will limit its investments to direct
obligations of the U.S. Treasury, including Treasury bills, notes and bonds, and
related repurchase agreement transactions, each having a remaining maturity of
not more than thirteen months at the time of purchase and will maintain a
dollar-weighted average portfolio maturity of not more than 90 days.

INVESTMENT RESTRICTIONS

The investment restrictions of each Fund and its corresponding
Portfolio are identical, unless otherwise specified. Accordingly, references
below to a Fund also include the Fund's corresponding Portfolio unless the
context requires otherwise; similarly, references to a Portfolio also include
its corresponding Fund unless the context requires otherwise.

The investment restrictions below have been adopted by the Trust with
respect to each Fund and, except as noted, by each corresponding Portfolio.
Except where otherwise noted, these investment restrictions are "fundamental"
policies which, under the 1940 Act, may not be changed without the vote of a
majority of the outstanding voting securities of the Fund or Portfolio, as the
case may be. A "majority of the outstanding voting securities" is defined in the
1940 Act as the lesser of (a) 67% or more of the voting securities present at a
meeting if the holders of more than 50% of the outstanding voting securities are
present or represented by proxy, or (b) more than 50% of the outstanding voting
securities. The percentage limitations contained in the restrictions below apply
at the time of the purchase of securities. Whenever a Fund is requested to vote
on a change in the fundamental investment restrictions of its corresponding
Portfolio, the Trust will hold a meeting of Fund shareholders and will cast its
votes as instructed by the Fund's shareholders.

The Funds and their corresponding portfolios:

1. May not make any investment inconsistent with the Fund's classification as a
diversified investment company under the Investment Company Act of 1940.

2. May not purchase any security which would cause the Fund to concentrate its
investments in the securities of issuers primarily engaged in any particular
industry except as permitted by the SEC. This restriction does not apply to
instruments considered to be domestic bank money market instruments.

3. May not issue senior securities, except as permitted under the Investment
Company Act of 1940 or any rule, order or interpretation thereunder;

4. May not borrow money, except to the extent permitted by applicable law;

5. May not underwrite securities of other issuers, except to the extent that the
Fund, in disposing of portfolio securities, may be deemed an underwriter within
the meaning of the 1933 Act;

6. May not purchase or sell real estate, except that, to the extent permitted by
applicable law, the Fund may (a) invest in securities or other instruments
directly or indirectly secured by real estate, and (b) invest in securities or
other instruments issued by issuers that invest in real estate;

7. May not purchase or sell commodities or commodity contracts unless acquired
as a result of ownership of securities or other instruments issued by persons
that purchase or sell commodities or commodities contracts; but this shall not
prevent the Fund from purchasing, selling and entering into financial futures
contracts (including futures contracts on indices of securities, interest rates
and currencies), options on financial futures contracts (including futures
contracts on indices of securities, interest rates and currencies), warrants,
swaps, forward contracts, foreign currency spot and forward contracts or other
derivative instruments that are not related to physical commodities; and

8. May make loans to other persons, in accordance with the Fund's
investment objective and policies and to the extent permitted by applicable law.

Non-Fundamental Investment Restrictions. The investment restrictions
described below are not fundamental policies of the Funds and their Portfolios
and may be changed by their Trustees. These non-fundamental investment policies
require that the Funds and their corresponding Portfolios:

(i) May not acquire any illiquid securities, such as repurchase agreements with
more than seven days to maturity or fixed time deposits with a duration of over
seven calendar days, if as a result thereof, more than 10% of the market value
of the Fund's total assets would be in investments which are illiquid;

(ii) May not purchase securities on margin, make short sales of securities, or
maintain a short position, provided that this restriction shall not be deemed to
be applicable to the purchase or sale of when-issued or delayed delivery
securities

(iii) May not acquire securities of other investment companies, except as
permitted by the 1940 Act or any order pursuant thereto.

Additional Non-Fundamental Investment Restriction - Prime Money Market
Fund. The investment restriction described below is not a fundamental policy of
the Prime Money Market Fund or its corresponding Portfolio and may be changed by
their respective Trustees. This non-fundamental investment policy requires that
the Prime Money Market Fund and its corresponding Portfolio may not:

(iv) enter into reverse repurchase agreements or borrow money, except from
banks for extraordinary or emergency purposes, if such obligations
exceed in the aggregate one-third of the market value of the Fund's
total assets, less liabilities other than obligations created by
reverse repurchase agreements and borrowings.

Notwithstanding any other fundamental or non-fundamental investment
restriction or policy, each Fund reserves the right, without the approval of
shareholders, to invest all of its assets in the securities of a single open-end
registered investment company with substantially the same investment objective,
restrictions and policies as the Fund.

There will be no violation of any investment restriction if that
restriction is complied with at the time the relevant action is taken
notwithstanding a later change in market value of an investment, in net or total
assets, in the securities rating of the investment, or any other later change.

For purposes of fundamental investment restrictions regarding industry
concentration, the Advisor may classify issuers by industry in accordance with
classifications set forth in the Directory of Companies Filing Annual Reports
With The Securities and Exchange Commission or other sources. In the absence of
such classification or if the Advisor determines in good faith based on its own
information that the economic characteristics affecting a particular issuer make
it more appropriately considered to be engaged in a different industry, the
Advisor may classify accordingly. For instance, personal credit finance
companies and business credit finance companies are deemed to be separate
industries and wholly owned finance companies are considered to be in the
industry of their parents if their activities are primarily related to financing
the activities of their parents.

Morgan Funds up to and including creating a separate board of trustees.

Each Trustee is currently paid an annual fee of $75,000 (adjusted as of
April 1, 1997) for serving as Trustee of the Trust, each of the Master
Portfolios (as defined below), the J.P. Morgan Funds and J.P. Morgan Series
Trust and is reimbursed for expenses incurred in connection with service as a

Chairman of Pierpont Group, Inc., compensation in the amount of $157,400,
contributed $23,610 to a defined contribution plan on his behalf and paid

(***) No investment company within the fund complex has a pension or
retirement plan. Currently there are 17 investment companies (14
investment companies comprising the Master Portfolios, the J.P. Morgan
Funds, the Trust and J.P. Morgan Series Trust) in the fund complex.

The Trustees decide upon general policies and are responsible for
overseeing the Trust's and Portfolio's business affairs. Each of the Portfolios
and the Trust has entered into a Fund Services Agreement with Pierpont Group,
Inc. to assist the Trustees in exercising their overall supervisory
responsibilities over the affairs of the Portfolios and the Trust. Pierpont
Group, Inc. was organized in July 1989 to provide services for The Pierpont
Family of Funds (now the J.P. Morgan Family of Funds), and the Trustees are the
equal and sole shareholders of Pierpont Group, Inc. The Trust and the Portfolios
have agreed to pay Pierpont Group, Inc. a fee in an amount representing its
reasonable costs in performing these services to the Trust, the Portfolios and
certain other registered investment companies subject to similar agreements with
Pierpont Group, Inc. These costs are periodically reviewed by the Trustees. The
principal offices of Pierpont Group, Inc. are located at 461 Fifth Avenue, New
York, New York 10017.

The aggregate fees paid to Pierpont Group, Inc. by each Portfolio
during the indicated fiscal periods are set forth below:

The Prime Money Market Portfolio -- For the fiscal years ended November 30,
1996, 1997 and 1998: $157,428, $143,027 and $173,032, respectively.

INVESTMENT ADVISOR

The Funds have not retained the services of an investment adviser
because each Fund seeks to achieve its investment objective by investing all of
its investable assets in a corresponding Portfolio. Subject to the supervision
of the Portfolio's Trustees, the Advisor makes each Portfolio's day-to-day
investment decisions, arranges for the execution of Portfolio transactions and
generally manages the Portfolio's investments. Effective October 1, 1998 each
Portfolio's investment advisor is JPMIM. Prior to that date, Morgan was the
investment advisor. JPMIM, a wholly owned subsidiary of J.P. Morgan & Co.
Incorporated ("J.P. Morgan"), is a registered investment adviser under the
Investment Advisers Act of 1940, as amended, which manages employee benefit
funds of corporations, labor unions and state and local governments and the
accounts of other institutional investors, including investment companies.
Certain of the assets of employee benefit accounts under its management are
invested in commingled pension trust funds for which Morgan serves as trustee.

J.P. Morgan, through the Advisor and other subsidiaries, acts as
investment advisor to individuals, governments, corporations, employee benefit
plans, mutual funds and other institutional investors with combined assets under
management of approximately $320 billion.

J.P. Morgan has a long history of service as adviser, underwriter and
lender to an extensive roster of major companies and as a financial advisor to
national governments. The firm, through its predecessor firms, has been in
business for over a century and has been managing investments since 1913.

The basis of the Advisor's investment process is fundamental investment
research as the firm believes that fundamentals should determine an asset's
value over the long term. J.P. Morgan currently employs over 100 full time
research analysts, among the largest research staffs in the money management
industry, in its investment management divisions located in New York, London,
Tokyo, Frankfurt, and Singapore to cover companies, industries and countries on
site. In addition, the investment management divisions employ approximately 300
capital market researchers, portfolio managers and traders. The Advisor's fixed
income investment process is based on analysis of real rates, sector
diversification and quantitative and credit analysis.

The investment advisory services the Advisor provides to the Portfolios
are not exclusive under the terms of the Advisory Agreements. The Advisor is
free to and does render similar investment advisory services to others. The
Advisor serves as investment advisor to personal investors and other investment
companies and acts as fiduciary for trusts, estates and employee benefit plans.
Certain of the assets of trusts and estates under management are invested in
common trust funds for which the Advisor serves as trustee. The accounts which
are managed or advised by the Advisor have varying investment objectives and the
Advisor invests assets of such accounts in investments substantially similar to,
or the same as, those which are expected to constitute the principal investments
of the Portfolios. Such accounts are supervised by officers and employees of the
Advisor who may also be acting in similar capacities for the Portfolios. See
"Portfolio Transactions."

Sector weightings are generally similar to a benchmark with the
emphasis on security selection as the method to achieve investment performance
superior to the benchmark. The benchmarks for the Portfolios in which the Funds
invest are currently: The Prime Money Market Portfolio--IBC's First Tier Money
Fund Average; The Treasury Money Market Portfolio--IBC's Treasury and Repo Money
Fund Average.

Morgan, also a wholly owned subsidiary of J.P. Morgan, is a bank holding
company organized under the laws of the State of Delaware. Morgan, whose
principal offices are at 60 Wall Street, New York, New York 10260, is a New York
trust company which conducts a general banking and trust business. Morgan is
subject to regulation by the New York State Banking Department and is a member
bank of the Federal Reserve System. Through offices in New York City and abroad,
Morgan offers a wide range of services, primarily to governmental,
institutional, corporate and high net worth individual customers in the United
States and throughout the world.

The Portfolios are managed by officers of the Advisor who, in acting
for their customers, including the Portfolios, do not discuss their investment
decisions with any personnel of J.P. Morgan or any personnel of other divisions
of the Advisor or with any of its affiliated persons, with the exception of
certain other investment management affiliates of J.P. Morgan.

As compensation for the services rendered and related expenses such as
salaries of advisory personnel borne by the Advisor under the Investment
Advisory Agreements, the Portfolio corresponding to each Fund has agreed to pay
the Advisor a fee, which is computed daily and may be paid monthly, equal to the
annual rates of 0.20% of each Portfolio's average daily net assets up to $1
billion and 0.10% of each Portfolio's average daily net assets in excess of $1
billion.

The table below sets forth for each Portfolio listed the advisory fees
paid to Morgan and JPMIM, as applicable, for the fiscal periods indicated. See
the Prospectus and below for applicable expense limitations.

The Prime Money Market Portfolio -- For the fiscal years ended November 30,
1996, 1997 and 1998: $4,503,793, $5,063,662 and $7,199,733, respectively.

The Treasury Money Market Portfolio -- For the period July 7, 1997 (commencement
of operations) through October 31, 1997 and for the fiscal year ended October
31, 1998: $49,123 and $1,080,743, respectively.

The Investment Advisory Agreements provide that they will continue in
effect for a period of two years after execution only if specifically approved
thereafter annually in the same manner as the Distribution Agreement. See
"Distributor" below. Each of the Investment Advisory Agreements will terminate
automatically if assigned and is terminable at any time without penalty by a
vote of a majority of the Portfolio's Trustees, or by a vote of the holders of a
majority of the Portfolio's outstanding voting securities, on 60 days' written
notice to the Advisor and by the Advisor on 90 days' written notice to the
Portfolio. See "Additional Information."

The Glass-Steagall Act and other applicable laws generally prohibit
banks such as the Advisor from engaging in the business of underwriting or
distributing securities, and the Board of Governors of the Federal Reserve
System has issued an interpretation to the effect that under these laws a bank
holding company registered under the federal Bank Holding Company Act or certain
subsidiaries thereof may not sponsor, organize, or control a registered open-end
investment company continuously engaged in the issuance of its shares, such as
the Trust. The interpretation does not prohibit a holding company or a
subsidiary thereof from acting as investment advisor and custodian to such an
investment company. The Advisor believes that it may perform the services for
the Portfolios contemplated by the Advisory Agreements without violation of the
Glass-Steagall Act or other applicable banking laws or regulations. State laws
on this issue may differ from the interpretation of relevant federal law, and
banks and financial institutions may be required to register as dealers pursuant
to state securities laws. However, it is possible that future changes in either
federal or state statutes and regulations concerning the permissible activities
of banks or trust companies, as well as further judicial or administrative
decisions and interpretations of present and future statutes and regulations,
might prevent the Advisor from continuing to perform such services for the
Portfolios.

If the Advisor were prohibited from acting as investment advisor to any
Portfolio, it is expected that the Trustees of the Portfolio would recommend to
investors that they approve the Portfolio's entering into a new investment
advisory agreement with another qualified investment advisor selected by the
Trustees.

Under separate agreements, Morgan provides certain financial, fund
accounting and administrative services to the Trust and the Portfolios and
shareholder services for the Trust. See "Services Agent" and "Shareholder
Servicing" below.

DISTRIBUTOR

FDI serves as the Trust's exclusive Distributor and holds itself
available to receive purchase orders for each of the Fund's shares. In that
capacity, FDI has been granted the right, as agent of the Trust, to solicit and
accept orders for the purchase of each of the Fund's shares in accordance with
the terms of the Distribution Agreement between the Trust and FDI. Under the
terms of the Distribution Agreement between FDI and the Trust, FDI receives no
compensation in its capacity as the Trust's distributor. FDI is a wholly owned
indirect subsidiary of Boston Institutional Group, Inc. FDI also serves as
exclusive placement agent for the Portfolio. FDI currently provides
administration and distribution services for a number of other investment
companies.

The Distribution Agreement shall continue in effect with respect to
each of the Funds for a period of two years after execution only if it is
approved at least annually thereafter (i) by a vote of the holders of a majority
of the Fund's outstanding shares or by its Trustees and (ii) by a vote of a
majority of the Trustees of the Trust who are not "interested persons" (as
defined by the 1940 Act) of the parties to the Distribution Agreement, cast in
person at a meeting called for the purpose of voting on such approval (see
"Trustees and Officers"). The Distribution Agreement will terminate
automatically if assigned by either party thereto and is terminable at any time
without penalty by a vote of a majority of the Trustees of the Trust, a vote of
a majority of the Trustees who are not "interested persons" of the Trust, or by
a vote of the holders of a majority of the Fund's outstanding shares as defined
under "Additional Information," in any case without payment of any penalty on 60
days' written notice to the other party. The principal offices of FDI are
located at 60 State Street, Suite 1300, Boston, Massachusetts 02109.

CO-ADMINISTRATOR

Under Co-Administration Agreements with the Trust and the Portfolios
dated August 1, 1996, FDI also serves as the Trust's and the Portfolios'
Co-Administrator. The Co-Administration Agreements may be renewed or amended by
the respective Trustees without a shareholder vote. The Co-Administration
Agreements are terminable at any time without penalty by a vote of a majority of
the Trustees of the Trust or the Portfolios, as applicable, on not more than 60
days' written notice nor less than 30 days' written notice to the other party.
The Co-Administrator may subcontract for the performance of its obligations,
provided, however, that unless the Trust or the Portfolios, as applicable,
expressly agrees in writing, the Co-Administrator shall be fully responsible for
the acts and omissions of any subcontractor as it would for its own acts or
omissions. See "Services Agent" below.

FDI (i) provides office space, equipment and clerical personnel for
maintaining the organization and books and records of the Trust and the
Portfolio; (ii) provides officers for the Trust and the Portfolio; (iii)
prepares and files documents required for notification of state securities
administrators; (iv) reviews and files marketing and sales literature; (v) files
Portfolio regulatory documents and mails Portfolio communications to Trustees
and investors; and (vi) maintains related books and records.

For its services under the Co-Administration Agreements, each Fund and
Portfolio has agreed to pay FDI fees equal to its allocable share of an annual
complex-wide charge of $425,000 plus FDI's out-of-pocket expenses. The amount
allocable to each Fund or Portfolio is based on the ratio of its net assets to
the aggregate net assets of the Trust, the Master Portfolios and certain other
investment companies subject to similar agreements with FDI.

The table below sets forth for each Fund listed and its corresponding
Portfolio the administrative fees paid to FDI for the fiscal periods indicated.

The Prime Money Market Portfolio -- For the period August 1, 1996 through
November 30, 1996, the fiscal year ended November 30, 1997 and the fiscal year
ended November 30, 1998: $33,012, $96,662 and $115,137, respectively.

The Treasury Money Market Portfolio -- For the period July 7, 1997 (commencement
of operations) through October 31, 1997 and for the fiscal year ended October
31, 1998: $406 and $7,258, respectively.

The table below sets forth for the Prime Money Market Portfolio the
administrative fees paid to Signature Broker-Dealer Services, Inc. (which
provided distribution and administrative services to the Trust and placement
agent and administrative services to the Portfolios prior to August 1, 1996) for
the fiscal periods indicated. See the Prospectus and below for applicable
expense limitations.

The Prime Money Market Portfolio -- For the period December 1, 1995 through July
31, 1996: $272,989.

SERVICES AGENT

The Trust, on behalf of each Fund, and the Portfolios have entered into
Administrative Services Agreements (the "Services Agreements") with Morgan
pursuant to which Morgan is responsible for certain administrative and related
services provided to each Fund and its corresponding Portfolio. The Services
Agreements may be terminated at any time, without penalty, by the Trustees or
Morgan, in each case on not more than 60 days' nor less than 30 days' written
notice to the other party.

Under the Services Agreements, each of the Funds and the Portfolios has
agreed to pay Morgan fees equal to its allocable share of an annual complex-wide
charge. This charge is calculated daily based on the aggregate net assets of the
Master Portfolios and J.P. Morgan Series Trust in accordance with the following
annual schedule: 0.09% of the first $7 billion of their aggregate average daily
net assets and 0.04% of their aggregate average daily net assets in excess of $7
billion, less the complex-wide fees payable to FDI. The portion of this charge
payable by each Fund and Portfolio is determined by the proportionate share that
its net assets bear to the total net assets of the Trust, the Master Portfolios,
the other investors in the Master Portfolios for which Morgan provides similar
services and J.P. Morgan Series Trust.

Under prior administrative services agreements in effect from December
29, 1995 through July 31, 1996, with Morgan, each Fund's corresponding Portfolio
(except the Treasury Money Market Portfolio) paid Morgan a fee equal to its
proportionate share of an annual complex-wide charge. This charge was calculated
daily based on the aggregate net assets of the Master Portfolios in accordance
with the following schedule: 0.06% of the first $7 billion of the Master
Portfolios' aggregate average daily net assets, and 0.03% of the Master
Portfolios' aggregate average daily net assets in excess of $7 billion.

Prior to December 29, 1995, the Trust and each Portfolio (except The
Treasury Money Market Portfolio) had entered into Financial and Fund Accounting
Services Agreements with Morgan, the provisions of which included certain of the
activities described above and, prior to September 1, 1995, also included
reimbursement of usual and customary expenses. The table below sets forth for
each Fund listed and its corresponding Portfolio the fees paid to Morgan as
Services Agent. See the Prospectus and below for applicable expense limitations.

The Prime Money Market Portfolio -- For the fiscal years ended November 30,
1996, 1997 and 1998: $891,730, $1,256,131 and $1,788,454, respectively.

The Treasury Money Market Portfolio -- For the period July 7, 1997 (commencement
of operations) through October 31, 1997 and for the fiscal year ended October
31, 1998: $7,289 and $155,752, respectively.

CUSTODIAN AND TRANSFER AGENT

State Street Bank and Trust Company ("State Street"), 225 Franklin
Street, Boston, Massachusetts 02110, serves as the Trust's and each Portfolio's
custodian and fund accounting agent and each Fund's transfer and dividend
disbursing agent. Pursuant to the Custodian Contracts, State Street is
responsible for maintaining the books of account and records of portfolio
transactions and holding portfolio securities and cash. The custodian maintains
portfolio transaction records. As transfer agent and dividend disbursing agent,
State Street is responsible for maintaining account records detailing the
ownership of Fund shares and for crediting income, capital gains and other
changes in share ownership to shareholder accounts.

SHAREHOLDER SERVICING

The Trust on behalf of each of the Funds has entered into a Shareholder
Servicing Agreement with Morgan pursuant to which Morgan acts as shareholder
servicing agent for its customers and for other Fund investors who are customers
of a Service Organization. Under this agreement, Morgan is responsible for
performing shareholder account, administrative and servicing functions, which
include but are not limited to, answering inquiries regarding account status and
history, the manner in which purchases and redemptions of Fund shares may be
effected, and certain other matters pertaining to a Fund; assisting customers in
designating and changing dividend options, account designations and addresses;
providing necessary personnel and facilities to coordinate the establishment and
maintenance of shareholder accounts and records with the Funds' transfer agent;
transmitting purchase and redemption orders to the Funds' transfer agent and
arranging for the wiring or other transfer of funds to and from customer
accounts in connection with orders to purchase or redeem Fund shares; verifying
purchase and redemption orders, transfers among and changes in accounts;
informing the Distributor of the gross amount of purchase orders for Fund
shares; monitoring the activities of the Funds' transfer agent; and providing
other related services.

Under the Shareholder Servicing Agreement, each Fund has agreed to pay
Morgan for these services a fee at the annual rate (expressed as a percentage of
the average daily net asset values of Fund shares owned by or for shareholders
for whom Morgan is acting as shareholder servicing agent) of 0.05%. Morgan acts
as shareholder servicing agent for all shareholders.

As discussed under "Investment Advisor," the Glass-Steagall Act and
other applicable laws and regulations limit the activities of bank holding
companies and certain of their subsidiaries in connection with registered
open-end investment companies. The activities of Morgan in acting as shareholder
servicing agent for Fund shareholders under the Shareholder Servicing Agreement
and providing administrative services to the Funds and the Portfolios under the
Services Agreements, and the activities of JPMIM in acting as Advisor to the
Portfolios under the Investment Advisory Agreements, may raise issues under
these laws. However, JPMIM and Morgan believe that they may properly perform
these services and the other activities described in the Prospectus without
violation of the Glass-Steagall Act or other applicable banking laws or
regulations.

If Morgan were prohibited from providing any of the services under the
Shareholder Servicing Agreement and the Services Agreements, the Trustees would
seek an alternative provider of such services. In such event, changes in the
operation of the Funds or the Portfolios might occur and a shareholder might no
longer be able to avail himself or herself of any services then being provided
to shareholders by Morgan.

SERVICE ORGANIZATION

The Trust, on behalf of each Fund, has adopted a service plan (the
"Plan") with respect to the shares which authorizes the Funds to compensate
Service Organizations for providing certain account administration and other
services to their customers who are beneficial owners of such shares. Pursuant
to the Plan, the Trust, on behalf of each Fund, enters into agreements with
Service Organizations which purchase shares on behalf of their customers
("Service Agreements"). Under such Service Agreements, the Service Organizations
may: (a) act, directly or through an agent, as the sole shareholder of record
and nominee for all customers, (b) maintain or assist in maintaining account
records for each customer who beneficially owns shares, and (c) process or
assist in processing customer orders to purchase, redeem and exchange shares,
and handle or assist in handling the transmission of funds representing the
customers' purchase price or redemption proceeds. As compensation for such
services, the Trust on behalf of each Fund pays each Service Organization a
service fee in an amount up to 0.25% (on an annualized basis) of the average
daily net assets of the shares of each Fund attributable to or held in the name
of such Service Organization for its customers.

Conflicts of interest restrictions (including the Employee Retirement
Income Security Act of 1974) may apply to a Service Organization's receipt of
compensation paid by the Trust in connection with the investment of fiduciary
funds in shares. Service Organizations, including banks regulated by the
Comptroller of the Currency, the Federal Reserve Board or the Federal Deposit
Insurance Corporation, and investment advisers and other money managers subject
to the jurisdiction of the Securities and Exchange Commission, the Department of
Labor or state securities commissions, are urged to consult legal advisers
before investing fiduciary assets in shares. In addition, under some state
securities laws, banks and other financial institutions purchasing shares on
behalf of their customers may be required to register as dealers.

The Trustees of the Trust, including a majority of Trustees who are not
interested persons of the Trust and who have no direct or indirect financial
interest in the operation of such Plan or the related Service Agreements,
initially voted to approve the Plan and Service Agreements at a meeting called
for the purpose of voting on such Plan and Service Agreements on April 9, 1997.
The Plan was approved by the initial shareholders of each Fund on June 3, 1997,
remains in effect until July 10, 1998 and will continue in effect thereafter
only if such continuance is specifically approved annually by a vote of the
Trustees in the manner described above. The Plan may not be amended to increase
materially the amount to be spent for the services described therein without
approval of the shareholders of the affected Fund, and all material amendments
of the Plan must also be approved by the Trustees in the manner described above.
The Plan may be terminated at any time by a majority of the Trustees as
described above or by vote of a majority of the outstanding shares of the
affected Fund. The Service Agreements may be terminated at any time, without
payment of any penalty, by vote of a majority of the disinterested Trustees as
described above or by a vote of a majority of the outstanding shares of the
affected Fund on not more than 60 days' written notice to any other party to the
Service Agreements. The Service Agreements shall terminate automatically if
assigned. So long as the Plans are in effect, the selection and nomination of
those Trustees who are not interested persons shall be determined by the
non-interested members of the Board of Trustees. The Trustees have determined
that, in their judgment, there is a reasonable likelihood that the Plan will
benefit the Funds and Fund shareholders. In the Trustees' quarterly review of
the Plan and Service Agreements, they will consider their continued
appropriateness and the level of compensation provided therein.

DISTRIBUTION PLAN

Rule 12b-1 (the "Rule") under the 1940 Act provides, among other
things, that an investment company may bear expenses of distributing its shares
only pursuant to a plan adopted in accordance with the Rule. On April 28, 1999,
the Trustees have adopted such a plan (the "Distribution Plan") with respect to
the Funds pursuant to which each Fund pays for distributing its shares at an
annual rate not to exceed 0.25% of the value of the average daily net assets of
the Fund. Under the Distribution Plan, the Fund may make payments to certain
financial institutions, securities dealers, and other industry professionals
that have entered into written agreements with the Fund in respect of these
services. The amounts to be paid to such institutions is based on the daily
value of shares owned by their clients. The fees payable under the Distribution
Plan for advertising, marketing and distributing are payable without regard to
actual expenses incurred. The Trustees believe that there is a reasonable
likelihood that the Distribution Plan will benefit each Fund and its
shareholders.

Quarterly reports of the amounts expended under the Distribution Plan,
and the purposes for which such expenditures were incurred, will be made to the
Trustees for their review. In addition, the Distribution Plan provides that it
may not be amended to increase materially the costs which holders of the Funds'
shares may bear for distribution without approval of such shareholders and that
all material amendments of the Distribution Plan must be approved by the
Trustees, and by the Trustees who are neither "interested persons" (as defined
in the 1940 Act) of the Trust nor have any direct or indirect financial interest
in the operation of the Distribution Plan or in the related Distribution Plan
agreements, by vote cast in person at a meeting called for the purpose of
considering such amendments. The Distribution Plan and related agreements are
subject to annual approval by such vote of the Trustees cast in person at a
meeting called for the purpose of voting on the Distribution Plan and related
agreements. The Distribution Plan is terminable at any time by vote of a
majority of the Trustees who are not "interested persons" and who have no direct
or indirect financial interest in the operation of the Distribution Plan or in
the related agreements or by vote of the holders of a majority of shares, as the
case may be. A related Distribution Plan agreement is terminable without
penalty, at any time, by such vote of the Trustees or by vote of the holders of
a majority of the Fund's shares upon not more than 60 days' written notice to
any other party to such agreement. A Distribution Plan agreement will terminate
automatically in the event of its assignment (as defined in the 1940 Act).

INDEPENDENT ACCOUNTANTS

The independent accountants of the Trust and the Portfolios are
PricewaterhouseCoopers LLP, 1177 Avenue of the Americas, New York, New York
10036. PricewaterhouseCoopers LLP conducts an annual audit of the financial
statements of each of the Funds and the Portfolios, assists in the preparation
and/or review of each of the Fund's and the Portfolio's federal and state income
tax returns and consults with the Funds and the Portfolios as to matters of
accounting and federal and state income taxation.

EXPENSES

In addition to the fees payable to Pierpont Group, Inc., JPMIM, Morgan,
FDI and Service Organizations under various agreements discussed under "Trustees
and Officers," "Investment Advisor," "Co-Administrator", "Distributor,"
"Services Agent" and "Shareholder Servicing" above, the Funds and the Portfolios
are responsible for usual and customary expenses associated with their
respective operations. Such expenses include organization expenses, legal fees,
accounting and audit expenses, insurance costs, the compensation and expenses of
the Trustees, costs associated with their registration fees under federal
securities laws, and extraordinary expenses applicable to the Funds or the
Portfolios. For the Funds, such expenses also include transfer, registrar and
dividend disbursing costs, the expenses of printing and mailing reports, notices
and proxy statements to Fund shareholders, and filing fees under state
securities laws. For the Portfolios, such expenses also include custodian fees.
Under fee arrangements prior to September 1, 1995, Morgan as Services Agent was
responsible for reimbursements to the Trust and the Portfolio and the usual
customary expenses described above (excluding organization and extraordinary
expenses, custodian fees and brokerage expenses). For additional information
regarding waivers or expense subsidies, see the Prospectus.

J.P. Morgan has agreed that it will reimburse the Funds noted below
until further notice to the extent necessary to maintain the Fund's total
operating expenses (which include expenses of the Fund and the Portfolio) at the
following annual rates of the Fund's average daily net assets.

Prime Money Market Fund: 0.70%
Treasury Money Market Fund: 0.70%

These limits do not cover extraordinary expenses. These reimbursement
arrangements can be changed at any time at the option of J.P. Morgan.

The table below sets forth for each Portfolio listed the fees and other
expenses J.P. Morgan reimbursed under the expense reimbursement arrangements
described above or pursuant to prior expense reimbursement arrangements for the
fiscal periods indicated.

The Prime Money Market Portfolio -- For the fiscal years ended November 30,
1996, 1997 and 1998: $9,993, N/A and N/A respectively.

The Treasury Money Market Portfolio -- For the period July 7, 1997 (commencement
of operations) through October 31, 1997 and for the fiscal year October 31,
1998: $118,095 and $828,462, respectively.

PURCHASE OF SHARES

Method of Purchase. Investors may open accounts with the Fund only
through the Distributor. All purchase transactions in Fund accounts are
processed by Morgan as shareholder servicing agent and the Fund is authorized to
accept any instructions relating to a Fund account from Morgan as shareholder
servicing agent for the customer. All purchase orders must be accepted by the
Distributor. Prospective investors who are not already customers of Morgan may
apply to become customers of Morgan for the sole purpose of Fund transactions.
There are no charges associated with becoming a Morgan customer for this
purpose. Morgan reserves the right to determine the customers that it will
accept, and the Trust reserves the right to determine the purchase orders that
it will accept.

References in the Prospectus and this Statement of Additional
Information to customers of Morgan or a Service Organization include customers
of their affiliates and references to transactions by customers with Morgan or a
Service Organization include transactions with their affiliates. Only Fund
investors who are using the services of a financial institution acting as
shareholder servicing agent pursuant to an agreement with the Trust on behalf of
a Fund may make transactions in shares of a Fund.

Shares may be purchased for accounts held in the name of a Service
Organization that provides certain account administration and other services to
its customers, including acting directly or through an agent as the sole
shareholder of record, maintenance or assistance in maintaining account records
and processing orders to purchase, redeem and exchange shares. Shares of each
Fund bear the cost of service fees at the annual rate of up to 0.25% of 1% of
the average daily net assets of such shares.

It is possible that an institution or its affiliate may offer shares of
different funds which invest in the same Portfolio to its customers and thus
receive different compensation with respect to different funds. Certain aspects
of the shares may be altered, after advance notice to shareholders, if it is
deemed necessary in order to satisfy certain tax regulatory requirements.

Each Fund may, at its own option, accept securities in payment for
shares. The securities delivered in such a transaction are valued by the method
described in "Net Asset Value" as of the day the Fund receives the securities.
This is a taxable transaction to the shareholder. Securities may be accepted in
payment for shares only if they are, in the judgment of the Advisor, appropriate
investments for the Fund's corresponding Portfolio. In addition, securities
accepted in payment for shares must: (i) meet the investment objective and
policies of the acquiring Fund's corresponding Portfolio; (ii) be acquired by
the applicable Fund for investment and not for resale (other than for resale to
the Fund's corresponding Portfolio); and (iii) be liquid securities which are
not restricted as to transfer either by law or liquidity of market. Each Fund
reserves the right to accept or reject at its own option any and all securities
offered in payment for its shares.

Prospective investors may purchase shares with the assistance of a
Service Organization, and the Service Organization may charge the investor a fee
for this service and other services it provides to its customers.

REDEMPTION OF SHARES

Investors may redeem shares as described in the Prospectus.
Shareholders redeeming shares of the Funds should be aware that the Funds
attempt to maintain a stable net asset value of $1.00 per share; however, there
can be no assurance that they will be able to continue to do so, and in that
case the net asset value of the Fund's shares might deviate from $1.00 per
share. Accordingly, a redemption request might result in payment of a dollar
amount which differs from the number of shares redeemed. See "Net Asset Value"
below.

If the Trust on behalf of a Fund and its corresponding Portfolio
determine that it would be detrimental to the best interest of the remaining
shareholders of a Fund to make payment wholly or partly in cash, payment of the
redemption price may be made in whole or in part by a distribution in kind of
securities from the Portfolio, in lieu of cash, in conformity with the
applicable rule of the SEC. If shares are redeemed in kind, the redeeming
shareholder might incur transaction costs in converting the assets into cash.
The method of valuing portfolio securities is described under "Net Asset Value,"
and such valuation will be made as of the same time the redemption price is
determined. The Trust on behalf of the Treasury Money Market Fund and its
corresponding Portfolio has elected to be governed by Rule 18f-1 under the 1940
Act pursuant to which the Fund and its corresponding Portfolio are obligated to
redeem shares solely in cash up to the lesser of $250,000 or one percent of the
net asset value of the Fund during any 90-day period for any one shareholder.
The Trust will redeem Fund shares in kind only if it has received a redemption
in kind from the corresponding Portfolio and therefore shareholders of the Fund
that receive redemptions in kind will receive securities of the Portfolio. The
Portfolio has advised the Trust that the Portfolio will not redeem in kind
except in circumstances in which the Fund is permitted to redeem in kind.

Further Redemption Information. Investors should be aware that
redemptions from a Fund may not be processed if a redemption request is not
submitted in proper form. To be in proper form, the Fund must have received the
shareholder's taxpayer identification number and address. In addition, if a
shareholder sends a check for the purchase of fund shares and shares are
purchased before the check has cleared, the transmittal of redemption proceeds
from the shares will occur upon clearance of the check which may take up to 15
days. The Trust, on behalf of a Fund, and the Portfolios reserve the right to
suspend the right of redemption and to postpone the date of payment upon
redemption as follows: (i) for up to seven days, (ii) during periods when the
New York Stock Exchange is closed for other than weekends and holidays or when
trading on such Exchange is restricted as determined by the SEC by rule or
regulation, (iii) during periods in which an emergency, as determined by the
SEC, exists that causes disposal by the Portfolio of, or evaluation of the net
asset value of, its portfolio securities to be unreasonable or impracticable, or
(iv) for such other periods as the SEC may permit.

EXCHANGE OF SHARES

An investor may exchange shares from any Fund into shares of any other
J.P. Morgan Institutional or J.P. Morgan mutual fund, without charge. An
exchange may be made so long as after the exchange the investor has shares, in
each fund in which he or she remains an investor, with a value of at least that
fund's minimum investment amount. Shareholders should read the prospectus of the
fund into which they are exchanging and may only exchange between fund accounts
that are registered in the same name, address and taxpayer identification
number. Shares are exchanged on the basis of relative net asset value per share.
Exchanges are in effect redemptions from one fund and purchases of another fund
and the usual purchase and redemption procedures and requirements are applicable
to exchanges. Shareholders subject to federal income tax who exchange shares in
one fund for shares in another fund may recognize capital gain or loss for
federal income tax purposes. Shares of the Fund to be acquired are purchased for
settlement when the proceeds from redemption become available. The Trust
reserves the right to discontinue, alter or limit the exchange privilege at any
time.

DIVIDENDS AND DISTRIBUTIONS

Each Fund declares and pays dividends and distributions as described in the
Prospectus. If a shareholder has elected to receive dividends and/or capital
gain distributions in cash and the postal or other delivery service is unable to
deliver checks to the shareholder's address of record, such shareholder's
distribution option will automatically be converted to having all dividend and
other distributions reinvested in additional shares. No interest will accrue on
amounts represented by uncashed distribution or redemption checks.

NET ASSET VALUE

Each of the Funds computes its net asset value once daily on Monday
through Friday as described in the Prospectus. The net asset value will not be
computed on the day the following legal holidays are observed: New Year's Day,
Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial Day,
Independence Day, Labor Day, Columbus Day, Veteran's Day, Thanksgiving Day, and
Christmas Day. In the event that trading in the money markets is scheduled to
end earlier than the close of the New York Stock Exchange in observance of these
holidays, the Funds and their corresponding Portfolios would expect to close for
purchases and redemptions an hour in advance of the end of trading in the money
markets. The Funds and the Portfolios may also close for purchases and
redemptions at such other times as may be determined by the Board of Trustees to
the extent permitted by applicable law. On any business day when the Public
Securities Association ("PSA") recommends that the securities market close
early, the Funds reserve the right to cease accepting purchase and redemption
orders for same business day credit at the time PSA recommends that the
securities market close. On days the Funds close early, purchase and redemption
orders received after the PSA-recommended closing time will be credited the next
business day. The days on which net asset value is determined are the Funds'
business days.

The net asset value of each Fund is equal to the value of the Fund's
investment in its corresponding Portfolio (which is equal to the Fund's pro rata
share of the total investment of the Fund and of any other investors in the
Portfolio less the Fund's pro rata share of the Portfolio's liabilities) less
the Fund's liabilities. The following is a discussion of the procedures used by
the Portfolios corresponding to each Fund in valuing their assets.

The Portfolios' portfolio securities are valued by the amortized cost
method. The purpose of this method of calculation is to attempt to maintain a
constant net asset value per share of the Fund of $1.00. No assurances can be
given that this goal can be attained. The amortized cost method of valuation
values a security at its cost at the time of purchase and thereafter assumes a
constant amortization to maturity of any discount or premium, regardless of the
impact of fluctuating interest rates on the market value of the instrument. If a
difference of more than 1/2 of 1% occurs between valuation based on the
amortized cost method and valuation based on market value, the Trustees will
take steps necessary to reduce such deviation, such as changing a Fund's
dividend policy, shortening the average portfolio maturity, realizing gains or
losses, or reducing the number of outstanding Fund shares. Any reduction of
outstanding shares will be effected by having each shareholder contribute to a
Fund's capital the necessary shares on a pro rata basis. Each shareholder will
be deemed to have agreed to such contribution in these circumstances by his
investment in the Funds. See "Taxes."

PERFORMANCE DATA

From time to time, the Funds may quote performance in terms of yield,
actual distributions, total return or capital appreciation in reports, sales
literature and advertisements published by the Trust. Current performance
information for the Funds may be obtained by calling the number provided on the
cover page of this Statement of Additional Information. See "Additional
Information" in the Prospectus. The performance information presented below for
the Prime Money Market Fund is that of the J.P. Morgan Prime Money Market Fund,
a separate feeder fund investing in the same master portfolio. The performance
information presented below for the Treasury Money Market Fund is that of the
J.P. Morgan Institutional Service Treasury Money Market Fund, a separate feeder
fund investing in the same master portfolio.

The historical performance information shown below reflects operating
expenses which were lower than those of the Funds. These returns are higher than
would have occurred if an investment in the Funds had been made during the
periods indicated. All performance information will be presented in accordance
with applicable SEC staff interpretations. The applicable financial information
in the registration statement for the J.P. Morgan Funds (Registration Nos.
033-54632 and 811-07340) and J.P. Morgan Institutional Funds (Registration Nos.
033-54642 and 811-07342) is incorporated herein by reference.

Yield Quotations. As required by regulations of the SEC, current yield
for the Funds is computed by determining the net change exclusive of capital
changes in the value of a hypothetical pre-existing account having a balance of
one share at the beginning of a seven-day calendar period, dividing the net
change in account value of the account at the beginning of the period, and
multiplying the return over the seven-day period by 365/7. For purposes of the
calculation, net change in account value reflects the value of additional shares
purchased with dividends from the original share and dividends declared on both
the original share and any such additional shares, but does not reflect realized
gains or losses or unrealized appreciation or depreciation. Effective yield for
each Fund is computed by annualizing the seven-day return with all dividends
reinvested in additional Fund shares.

Below is set forth historical yield information for the Prime Money Market
Fund's related series of the J.P. Morgan Funds and the Treasury Money Market
Fund's related series of J.P. Morgan Institutional Service Funds for the periods
indicated:

Prime Money Market Fund (11/30/98): 7-day current yield: 4.84%; 7-day
effective yield: 4.80%.

Treasury Money Market Fund (10/31/98): 7-day current yield: 4.70%; 7-day
effective yield: 4.81%.

Total Return Quotations. Below is set forth historical return information
for the Prime Money Market Fund's related series of the J.P. Morgan Funds and
the Treasury Money Market Fund's related series of J.P. Morgan Institutional
Service Funds for the periods indicated:

Prime Money Market Fund (11/30/98): Average annual total return, 1 year:
5.40%; average annual total return, 5 years: 5.10%; average annual total return,
10 years: 5.56%; aggregate total return, 1 year: 5.40%; aggregate total return,
5 years: 28.25%; aggregate total return, 10 years: 71.79%.

return, 1 year: 5.27%; aggregate total return, 5 years: N/A; aggregate total
return, commencement of operations (July 7, 1997) to period end: 7.06%.

General. A Fund's performance will vary from time to time depending
upon market conditions, the composition of its corresponding Portfolio, and its
operating expenses. Consequently, any given performance quotation should not be
considered representative of a Fund's performance for any specified period in
the future. In addition, because performance will fluctuate, it may not provide
a basis for comparing an investment in a Fund with certain bank deposits or
other investments that pay a fixed yield or return for a stated period of time.

Comparative performance information may be used from time to time in
advertising the Funds' shares, including appropriate market indices including
the benchmarks indicated under "Investment Advisor" above or data from Lipper
Analytical Services, Inc., Micropal, Inc., Ibbotson Associates, Morningstar
Inc., the Dow Jones Industrial Average and other industry publications.

From time to time, the Funds may, in addition to any other permissible
information, include the following types of information in advertisements,
supplemental sales literature and reports to shareholders: (1) discussions of
general economic or financial principles (such as the effects of compounding and
the benefits of dollar-cost averaging); (2) discussions of general economic
trends; (3) presentations of statistical data to supplement such discussions;
(4) descriptions of past or anticipated portfolio holdings for one or more of
the Funds; (5) descriptions of investment strategies for one or more of the
Funds; (6) descriptions or comparisons of various savings and investment
products (including, but not limited to, qualified retirement plans and
individual stocks and bonds), which may or may not include the Funds; (7)
comparisons of investment products (including the Funds) with relevant markets
or industry indices or other appropriate benchmarks; (8) discussions of Fund
rankings or ratings by recognized rating organizations; and (9) discussions of
various statistical methods quantifying the Fund's volatility relative to its
benchmark or to past performance, including risk adjusted measures. The Funds
may also include calculations, such as hypothetical compounding examples, which
describe hypothetical investment results in such communications. Such
performance examples will be based on an express set of assumptions and are not
indicative of the performance of any of the Funds.

PORTFOLIO TRANSACTIONS

The Advisor places orders for all Portfolios for all purchases and sales of
portfolio securities, enters into repurchase agreements, and may enter into
reverse repurchase agreements and execute loans of portfolio securities on
behalf of all the Portfolios. See "Investment Objectives and Policies."

Fixed income and debt securities are generally traded at a net price
with dealers acting as principal for their own accounts without a stated
commission. The price of the security usually includes profit to the dealers. In
underwritten offerings, securities are purchased at a fixed price which includes
an amount of compensation to the underwriter, generally referred to as the
underwriter's concession or discount. On occasion, certain securities may be
purchased directly from an issuer, in which case no commissions or discounts are
paid.

Portfolio transactions for the Portfolios will be undertaken principally to
accomplish a Portfolio's objective in relation to expected movements in the
general level of interest rates. The Portfolios may engage in short-term trading
consistent with their objectives. See "Investment Objectives and Policies --
Portfolio Turnover."

In connection with portfolio transactions for the Portfolios, the
Advisor intends to seek best execution on a competitive basis for both purchases
and sales of securities.

The Portfolios have a policy of investing only in securities with
maturities of not more than thirteen months, which will result in high portfolio
turnovers. Since brokerage commissions are not normally paid on investments
which the Portfolios make, turnover resulting from such investments should not
adversely affect the net asset value or net income of the Portfolios.

Subject to the overriding objective of obtaining best execution of
orders, the Advisor may allocate a portion of a Portfolio's brokerage
transactions to affiliates of the Advisor. In order for affiliates of the
Advisor to effect any portfolio transactions for a Portfolio, the commissions,
fees or other remuneration received by such affiliates must be reasonable and
fair compared to the commissions, fees, or other remuneration paid to other
brokers in connection with comparable transactions involving similar securities
being purchased or sold on a securities exchange during a comparable period of
time. Furthermore, the Trustees of each Portfolio, including a majority of the
Trustees who are not "interested persons," have adopted procedures which are
reasonably designed to provide that any commissions, fees, or other remuneration
paid to such affiliates are consistent with the foregoing standard.

Portfolio securities will not be purchased from or through or sold to
or through the Co-Administrator, the Distributor or the Advisor or any other
"affiliated person" (as defined in the 1940 Act) of the Co-Administrator,
Distributor or Advisor when such entities are acting as principals, except to
the extent permitted by law. In addition, the Portfolios will not purchase
securities during the existence of any underwriting group relating thereto of
which the Advisor or an affiliate of the Advisor is a member, except to the
extent permitted by law.

On those occasions when the Advisor deems the purchase or sale of a
security to be in the best interests of a Portfolio as well as other customers
including other Portfolios, the Advisor to the extent permitted by applicable
laws and regulations, may, but is not obligated to, aggregate the securities to
be sold or purchased for a Portfolio with those to be sold or purchased for
other customers in order to obtain best execution, including lower brokerage
commissions if appropriate. In such event, allocation of the securities so
purchased or sold as well as any expenses incurred in the transaction will be
made by the Advisor in the manner it considers to be most equitable and
consistent with its fiduciary obligations to a Portfolio. In some instances,
this procedure might adversely affect a Portfolio.

MASSACHUSETTS TRUST

The Trust is a trust fund of the type commonly known as a
"Massachusetts business trust" of which each Fund is a separate and distinct
series. A copy of the Declaration of Trust for the Trust is on file in the
office of the Secretary of The Commonwealth of Massachusetts. The Declaration of
Trust and the By-Laws of the Trust are designed to make the Trust similar in
most respects to a Massachusetts business corporation. The principal distinction
between the two forms concerns shareholder liability described below.

Effective January 1, 1998, the name of the Trust was changed from "The JPM
Institutional Funds" to "J.P. Morgan Institutional Funds."

Under Massachusetts law, shareholders of such a trust may, under
certain circumstances, be held personally liable as partners for the obligations
of the trust which is not the case for a corporation. However, the Trust's
Declaration of Trust provides that the shareholders shall not be subject to any
personal liability for the acts or obligations of any Fund and that every
written agreement, obligation, instrument or undertaking made on behalf of any
Fund shall contain a provision to the effect that the shareholders are not
personally liable thereunder.

No personal liability will attach to the shareholders under any
undertaking containing such provision when adequate notice of such provision is
given, except possibly in a few jurisdictions. With respect to all types of
claims in the latter jurisdictions, (i) tort claims, (ii) contract claims where
the provision referred to is omitted from the undertaking, (iii) claims for
taxes, and (iv) certain statutory liabilities in other jurisdictions, a
shareholder may be held personally liable to the extent that claims are not
satisfied by a Fund. However, upon payment of such liability, the shareholder
will be entitled to reimbursement from the general assets of a Fund. The
Trustees intend to conduct the operations of the Trust in such a way so as to
avoid, as far as possible, ultimate liability of the shareholders for
liabilities of the Funds.

The Trust's Declaration of Trust further provides that the name of the
Trust refers to the Trustees collectively as Trustees, not as individuals or
personally, that no Trustee, officer, employee or agent of a Fund is liable to a
Fund or to a shareholder, and that no Trustee, officer, employee, or agent is
liable to any third persons in connection with the affairs of a Fund, except as
such liability may arise from his or its own bad faith, willful misfeasance,
gross negligence or reckless disregard of his or its duties to such third
persons. It also provides that all third persons shall look solely to Fund
property for satisfaction of claims arising in connection with the affairs of a
Fund. With the exceptions stated, the Trust's Declaration of Trust provides that
a Trustee, officer, employee, or agent is entitled to be indemnified against all
liability in connection with the affairs of a Fund.

The Trust shall continue without limitation of time subject to the
provisions in the Declaration of Trust concerning termination by action of the
shareholders or by action of the Trustees upon notice to the shareholders.

DESCRIPTION OF SHARES

The Trust is an open-end management investment company organized as a
Massachusetts business trust in which each Fund represents a separate series of
shares of beneficial interest. See "Massachusetts Trust."

The Declaration of Trust permits the Trustees to issue an unlimited
number of full and fractional shares ($0.001 par value) of one or more series
and classes within any series and to divide or combine the shares (of any
series, if applicable) without changing the proportionate beneficial interest of
each shareholder in a Fund (or in the assets of other series, if applicable).
Each share represents an equal proportional interest in a Fund with each other
share. Upon liquidation of a Fund, holders are entitled to share pro rata in the
net assets of a Fund available for distribution to such shareholders. See
"Massachusetts Trust." Shares of a Fund have no preemptive or conversion rights
and are fully paid and nonassessable. The rights of redemption and exchange are
described in the Prospectus and elsewhere in this Statement of Additional
Information.

The shareholders of the Trust are entitled to one vote for each dollar
of net asset value (or a proportionate fractional vote in respect of a
fractional dollar amount), on matters on which shares of the Fund shall be
entitled to vote. Subject to the 1940 Act, the Trustees themselves have the
power to alter the number and the terms of office of the Trustees, to lengthen
their own terms, or to make their terms of unlimited duration subject to certain
removal procedures, and appoint their own successors, provided, however, that
immediately after such appointment the requisite majority of the Trustees have
been elected by the shareholders of the Trust. The voting rights of shareholders
are not cumulative so that holders of more than 50% of the shares voting can, if
they choose, elect all Trustees being selected while the shareholders of the
remaining shares would be unable to elect any Trustees. It is the intention of
the Trust not to hold meetings of shareholders annually. The Trustees may call
meetings of shareholders for action by shareholder vote as may be required by
either the 1940 Act or the Trust's Declaration of Trust.

Shareholders of the Trust have the right, upon the declaration in
writing or vote of more than two-thirds of its outstanding shares, to remove a
Trustee. The Trustees will call a meeting of shareholders to vote on removal of
a Trustee upon the written request of the record holders of 10% of the Trust's
shares. In addition, whenever ten or more shareholders of record who have been
such for at least six months preceding the date of application, and who hold in
the aggregate either shares having a net asset value of at least $25,000 or at
least 1% of the Trust's outstanding shares, whichever is less, shall apply to
the Trustees in writing, stating that they wish to communicate with other
shareholders with a view to obtaining signatures to request a meeting for the
purpose of voting upon the question of removal of any Trustee or Trustees and
accompanied by a form of communication and request which they wish to transmit,
the Trustees shall within five business days after receipt of such application
either: (1) afford to such applicants access to a list of the names and
addresses of all shareholders as recorded on the books of the Trust; or (2)
inform such applicants as to the approximate number of shareholders of record,
and the approximate cost of mailing to them the proposed communication and form
of request. If the Trustees elect to follow the latter course, the Trustees,
upon the written request of such applicants, accompanied by a tender of the
material to be mailed and of the reasonable expenses of mailing, shall, with
reasonable promptness, mail such material to all shareholders of record at their
addresses as recorded on the books, unless within five business days after such
tender the Trustees shall mail to such applicants and file with the SEC,
together with a copy of the material to be mailed, a written statement signed by
at least a majority of the Trustees to the effect that in their opinion either
such material contains untrue statements of fact or omits to state facts
necessary to make the statements contained therein not misleading, or would be
in violation of applicable law, and specifying the basis of such opinion. After
opportunity for hearing upon the objections specified in the written statements
filed, the SEC may, and if demanded by the Trustees or by such applicants shall,
enter an order either sustaining one or more of such objections or refusing to
sustain any of them. If the SEC shall enter an order refusing to sustain any of
such objections, or if, after the entry of an order sustaining one or more of
such objections, the SEC shall find, after notice and opportunity for hearing,
that all objections so sustained have been met, and shall enter an order so
declaring, the Trustees shall mail copies of such material to all shareholders
with reasonable promptness after the entry of such order and the renewal of such
tender.

The Trustees have authorized the issuance and sale to the public of
shares of 24 series of the Trust. The Trustees have no current intention to
create any classes within the initial series or any subsequent series. The
Trustees may, however, authorize the issuance of shares of additional series and
the creation of classes of shares within any series with such preferences,
privileges, limitations and voting and dividend rights as the Trustees may
determine. The proceeds from the issuance of any additional series would be
invested in separate, independently managed portfolios with distinct investment
objectives, policies and restrictions, and share purchase, redemption and net
asset valuation procedures. Any additional classes would be used to distinguish
among the rights of different categories of shareholders, as might be required
by future regulations or other unforeseen circumstances. All consideration
received by the Trust for shares of any additional series or class, and all
assets in which such consideration is invested, would belong to that series or
class, subject only to the rights of creditors of the Trust and would be subject
to the liabilities related thereto. Shareholders of any additional series or
class will approve the adoption of any management contract or distribution plan
relating to such series or class and of any changes in the investment policies
related thereto, to the extent required by the 1940 Act.

For information relating to mandatory redemption of Fund shares or
their redemption at the option of the Trust under certain circumstances, see the
Prospectus.

SPECIAL INFORMATION CONCERNING INVESTMENT STRUCTURE

Unlike other mutual funds which directly acquire and manage their own
portfolio of securities, each Fund is an open-end management investment company
which seeks to achieve its investment objective by investing all of its
investable assets in a corresponding Master Portfolio, a separate registered
investment company with the same investment objective and policies as the Fund.
Generally, when a Master Portfolio seeks a vote to change a fundamental
investment restriction, its feeder fund(s) will hold a shareholder meeting and
cast its vote proportionately, as instructed by its shareholders. Fund
shareholders are entitled to one vote for each dollar of net asset value (or a
proportionate fractional vote in respect of a fractional dollar amount), on
matters on which shares of the Fund shall be entitled to vote.

In addition to selling a beneficial interest to a Fund, a Portfolio may
sell beneficial interests to other mutual funds or institutional investors. Such
investors will invest in the Portfolio on the same terms and conditions and will
bear a proportionate share of the Portfolio's expenses. However, the other
investors investing in the Portfolio may sell shares of their own fund using a
different pricing structure than the Fund. Such different pricing structures may
result in differences in returns experienced by investors in other funds that
invest in the Portfolio. Such differences in returns are not uncommon and are
present in other mutual fund structures. Information concerning other holders of
interests in the Portfolio is available from Morgan at (800) 521-5411.

The Trust may withdraw the investment of a Fund from a Portfolio at any
time if the Board of Trustees of the Trust determines that it is in the best
interests of the Fund to do so. Upon any such withdrawal, the Board of Trustees
would consider what action might be taken, including the investment of all the
assets of the Fund in another pooled investment entity having the same
investment objective and restrictions in accordance with the investment policies
with respect to the Portfolio described above and in each Fund's Prospectus.

Certain changes in a Portfolio's fundamental investment policies or
restrictions, or a failure by a Fund's shareholders to approve such change in
the Portfolio's investment restrictions, may require withdrawal of the Fund's
interest in the Portfolio. Any such withdrawal could result in a distribution in
kind of portfolio securities (as opposed to a cash distribution) from the
Portfolio which may or may not be readily marketable. The distribution in kind
may result in the Fund having a less diversified portfolio of investments or
adversely affect the Fund's liquidity, and the Fund could incur brokerage, tax
or other charges in converting the securities to cash. Notwithstanding the
above, there are other means for meeting shareholder redemption requests, such
as borrowing.

Smaller funds investing in a Portfolio may be materially affected by
the actions of larger funds investing in the Portfolio. For example, if a large
fund withdraws from the Portfolio, the remaining funds may subsequently
experience higher pro rata operating expenses, thereby producing lower returns.

Additionally, because a Portfolio would become smaller, it may become
less diversified, resulting in potentially increased portfolio risk (however,
these possibilities also exist for traditionally structured funds which have
large or institutional investors who may withdraw from a fund). Also, funds with
a greater pro rata ownership in the Portfolio could have effective voting
control of the operations of the Portfolio. Whenever the Fund is requested to
vote on matters pertaining to the Portfolio (other than a vote by the Fund to
continue the operation of the Portfolio upon the withdrawal of another investor
in the Portfolio), the Trust will hold a meeting of shareholders of the Fund and
will cast all of its votes proportionately as instructed by the Fund's
shareholders. The Trust will vote the shares held by Fund shareholders who do
not give voting instructions in the same proportion as the shares of Fund
shareholders who do give voting instructions. Shareholders of the Fund who do
not vote will have no effect on the outcome of such matters.

TAXES

The following discussion of tax consequences is based on U.S. federal
tax laws in effect on the date of this Prospectus. These laws and regulations
are subject to change by legislative or administrative action.

Each Fund intends to qualify and remain qualified as a regulated
investment company under Subchapter M of the Code. As a regulated investment
company, a Fund must, among other things, (a) derive at least 90% of its gross
income from dividends, interest, payments with respect to loans of stock and
securities, gains from the sale or other disposition of stock, securities or
foreign currency and other income (including but not limited to gains from
options, futures, and forward contracts) derived with respect to its business of
investing in such stock, securities or foreign currency; and (b) diversify its
holdings so that, at the end of each fiscal quarter of its taxable year, (i) at
least 50% of the value of the Fund's total assets is represented by cash, cash
items, U.S. Government securities, investments of other regulated investment
companies, and other securities limited, in respect of any one issuer, to an
amount not greater than 5% of the Fund's total assets, and 10% of the
outstanding voting securities of such issuer, and (ii) not more than 25% of the
value of its total assets is invested in the securities of any one issuer (other
than U.S. Government securities or securities of other regulated investment
companies). As a regulated investment company, a Fund (as opposed to its
shareholders) will not be subject to federal income taxes on the net investment
income and capital gain that it distributes to its shareholders, provided that
at least 90% of its net investment income and realized net short-term capital
gain in excess of net long-term capital loss for the taxable year is distributed
in accordance with the Code's timing requirements.

Under the Code, a Fund will be subject to a 4% excise tax on a portion
of its undistributed taxable income and capital gains if it fails to meet
certain distribution requirements by the end of the calendar year. Each Fund
intends to make distributions in a timely manner and accordingly does not expect
to be subject to the excise tax.

For federal income tax purposes, dividends that are declared by a Fund
in October, November or December as of a record date in such month and actually
paid in January of the following year will be treated as if they were paid on
December 31 of the year declared. Therefore, such dividends generally, will be
taxable to a shareholder in the year declared rather than the year paid.

Distributions of net investment income and realized net short-term
capital gains in excess of net long-term capital loss (other than exempt
interest dividends) are generally taxable to shareholders of the Funds as
ordinary income whether such distributions are taken in cash or reinvested in
additional shares. Distributions to corporate shareholders of the Funds are not
eligible for the dividends received deduction. Distributions of net long-term
capital gains (i.e., net long-term capital gains in excess of net short-term
capital loss) are taxable to shareholders of a Fund as long-term capital gain,
regardless of whether such distributions are taken in cash or reinvested in
additional shares and regardless of how long a shareholder has held shares in
the Fund. In general, long-term capital gain of an individual shareholder will
be subject to a 20% rate of tax.

To maintain a constant $1.00 per share net asset value, the Trustees of
the Trust may direct that the number of outstanding shares be reduced pro rata.
If this adjustment is made, it will reflect the lower market value of portfolio
securities and not realized losses. The adjustment may result in a shareholder
having more dividend income than net income in his account for a period. When
the number of outstanding shares of a Fund is reduced, the shareholder's basis
in the shares of the Fund may be adjusted to reflect the difference between
taxable income and net dividends actually distributed. This difference may be
realized as a capital loss when the shares are liquidated. Subject to certain
limited exceptions, capital losses cannot be used to offset ordinary income. See
"Net Asset Value."

Gains or losses on sales of portfolio securities will be treated as
long-term capital gains or losses if the securities have been held for more than
one year except in certain cases where, if applicable a put is acquired or a
call option is written thereon or straddle rules are otherwise applicable. Other
gains or losses on the sale of securities will be short-term capital gains or
losses. Gains and losses on the sale, lapse or other termination of options on
securities will be treated as gains and losses from the sale of securities. If
an option written by a Portfolio lapses or is terminated through a closing
transaction, such as a repurchase by the Portfolio of the option from its
holder, the Portfolio will realize a short-term capital gain or loss, depending
on whether the premium income is greater or less than the amount paid by the
Portfolio in the closing transaction. If securities are purchased by a Portfolio
pursuant to the exercise of a put option written by it, the Portfolio will
subtract the premium received from its cost basis in the securities purchased.

Any distribution of net investment income or capital gains will have
the effect of reducing the net asset value of Fund shares held by a shareholder
by the same amount as the distribution. If the net asset value of the shares is
reduced below a shareholder's cost as a result of such a distribution, the
distribution, although constituting a return of capital to the shareholder, will
be taxable as described above.

Any gain or loss realized on the redemption or exchange of Fund shares
by a shareholder who is not a dealer in securities will be treated as long-term
capital gain or loss if the shares have been held for more than one year, and
otherwise as short-term capital gain or loss. Long-term capital gain of an
individual holder is subject to maximum tax rate of 20%. However, any loss
realized by a shareholder upon the redemption or exchange of shares in the Fund
held for six months or less will be treated as a long-term capital loss to the
extent of any long-term capital gain distributions received by the shareholder
with respect to such shares. Investors are urged to consult their tax advisors
concerning the limitations on the deductibility of capital losses. Additionally,
any loss realized on a redemption or exchange of shares of a Fund will be
disallowed to the extent the shares disposed of are replaced within a period of
61 days beginning 30 days before such disposition, such as pursuant to
reinvestment of a dividend in shares of the Fund.

If a correct and certified taxpayer identification number is not on
file, the Fund is required, subject to certain exemptions, to withold 31% of
certain payments made or distributions declared to non-corporate shareholders.

Foreign Shareholders. Dividends of net investment income and
distributions of realized net short-term gain in excess of net long-term loss to
a shareholder who, as to the United States, is a nonresident alien individual,
fiduciary of a foreign trust or estate, foreign corporation or foreign
partnership (a "foreign shareholder") will be subject to U.S. withholding tax at
the rate of 30% (or lower treaty rate) unless the dividends are effectively
connected with a U.S. trade or business of the shareholder, in which case the
dividends will be subject to tax on a net income basis at the graduated rates
applicable to U.S. individuals or domestic corporations. Distributions treated
as long term capital gains to foreign shareholders will not be subject to U.S.
tax unless the distributions are effectively connected with the shareholder's
trade or business in the United States or, in the case of a shareholder who is a
nonresident alien individual, the shareholder was present in the United States
for more than 182 days during the taxable year and certain other conditions are
met.

In the case of a foreign shareholder who is a nonresident alien
individual or foreign entity, a Fund may be required to withhold U.S. federal
income tax as "backup withholding" at the rate of 31% from distributions treated
as long-term capital gains and from the proceeds of redemptions, exchanges or
other dispositions of Fund shares unless IRS Form W-8 is provided. Transfers by
gift of shares of a Fund by a foreign shareholder who is a nonresident alien
individual will not be subject to U.S. federal gift tax, but the value of shares
of the Fund held by such a shareholder at his or her death will be includible in
his or her gross estate for U.S. federal estate tax purposes.

State and Local Taxes. Each Fund may be subject to state or local taxes
in jurisdictions in which the Fund is deemed to be doing business. In addition,
the treatment of a Fund and its shareholders in those states which have income
tax laws might differ from treatment under the federal income tax laws.
Shareholders should consult their own tax advisors with respect to any state or
local taxes.

Other Taxation. The Trust is organized as a Massachusetts business
trust and, under current law, neither the Trust nor any Fund is liable for any
income or franchise tax in The Commonwealth of Massachusetts, provided that each
Fund continues to qualify as a regulated investment company under Subchapter M
of the Code. The Portfolios are organized as New York trusts. The Portfolios are
not subject to any federal income taxation or income or franchise tax in the
State of New York or The Commonwealth of Massachusetts. The investment by a Fund
in its corresponding Portfolio does not cause the Fund to be liable for any
income or franchise tax in the State of New York.

The Year 2000 Initiative

With the new millennium rapidly approaching, organizations are
examining their computer systems to ensure they are year 2000 compliant. The
issue, in simple terms, is that many existing computer systems use only two
numbers to identify a year in the date field with the assumption that the first
two digits are always 19. As the century is implied in the date, on January 1,
2000, computers that are not year 2000 compliant will assume the year is 1900.
Systems that calculate, compare, or sort using the incorrect date will cause
erroneous results, ranging from system malfunctions to incorrect or incomplete
transaction processing. If not remedied, potential risks include business
interruption or shutdown, financial loss, reputation loss, and/or legal
liability.

J.P. Morgan has undertaken a firmwide initiative to address the year
2000 issue and has developed a comprehensive plan to prepare, as appropriate,
its computer systems. Each business line has taken responsibility for
identifying and fixing the problem within its own area of operation and for
addressing all interdependencies. A multidisciplinary team of internal and
external experts supports the business teams by providing direction and firmwide
coordination. Working together, the business and multidisciplinary teams have
completed a thorough education and awareness initiative and a global inventory
and assessment of J.P. Morgan's technology and application portfolio to
understand the scope of the year 2000 impact at J.P. Morgan. J.P. Morgan
presently is renovating and testing these technologies and applications in
partnership with external consulting and software development organizations, as
well as with year 2000 tool providers. J.P. Morgan has substantially completed
renovation, testing, and validation of its key systems and is preparing to
participate in industry-wide testing (or streetwide testing) in 1999. J.P.
Morgan is also working with key external parties, including clients,
counterparties, vendors, exchanges, depositories, utilities, suppliers, agents
and regulatory agencies, to stem the potential risks the year 2000 problem poses
to J.P. Morgan and to the global financial community. For potential failure
scenarios where the risks are deemed significant and where such risk is
considered to have a higher probability of occurrence, J.P. Morgan will attempt
to develop business recovery/contingency plans. These plans, which are being
developed in the first half of 1999, will define the infrastructure that should
be put in place for managing a failure during the millennium event itself.

Costs associated with efforts to prepare J.P. Morgan's systems for the
year 2000 approximated $95 million in 1997 and $112 million for the first nine
months of 1998. In 1999, J.P. Morgan is continuing its efforts to prepare its
systems for the year 2000. The total cost to become year-2000 compliant is
estimated at $300 million (for firmwide systems upgrade, not just for systems
relating to mutual funds), for internal systems renovation and testing, testing
equipment, and both internal and external resources working on the project. The
costs associated with J.P. Morgan becoming year-2000 compliant will be borne by
J.P. Morgan and not the Funds.

APPENDIX A

Description of Security Ratings

STANDARD & POOR'S

Corporate and Municipal Bonds

AAA - Debt rated AAA have the highest ratings assigned by Standard & Poor's
to a debt obligation. Capacity to pay interest and repay principal is extremely
strong.

AA - Debt rated AA have a very strong capacity to pay interest and repay
principal and differ from the highest rated issues only in a small degree.

A - Debt rated A have a strong capacity to pay interest and repay principal
although they are somewhat more susceptible to the adverse effects of changes in
circumstances and economic conditions than debt in higher rated categories.

BBB - Debt rated BBB are regarded as having an adequate capacity to pay
interest and repay principal. Whereas they normally exhibit adequate protection
parameters, adverse economic conditions or changing circumstances are more
likely to lead to a weakened capacity to pay interest and repay principal for
debt in this category than for debt in higher rated categories.

Commercial Paper, including Tax Exempt

A - Issues assigned this highest rating are regarded as having the greatest
capacity for timely payment. Issues in this category are further refined with
the designations 1, 2, and 3 to indicate the relative degree of safety.

A-1 - This designation indicates that the degree of safety regarding timely
payment is very strong.

Short-Term Tax-Exempt Notes

SP-1 - The short-term tax-exempt note rating of SP-1 is the highest rating
assigned by Standard & Poor's and has a very strong or strong capacity to
pay principal and interest. Those issues determined to possess
overwhelming safety characteristics are given a "plus" (+) designation.

SP-2 - The short-term tax-exempt note rating of SP-2 has a satisfactory
capacity to pay principal and interest.

<PAGE>

MOODY'S

Corporate and Municipal Bonds

Aaa - Bonds which are rated Aaa are judged to be of the best quality. They
carry the smallest degree of investment risk and are generally referred to as
"gilt edge." Interest payments are protected by a large or by an exceptionally
stable margin and principal is secure. While the various protective elements are
likely to change, such changes as can be visualized are most unlikely to impair
the fundamentally strong position of such issues.

Aa - Bonds which are rated Aa are judged to be of high quality by all
standards. Together with the Aaa group they comprise what are generally known as
high grade bonds. They are rated lower than the best bonds because margins of
protection may not be as large as in Aaa securities or fluctuation of protective
elements may be of greater amplitude or there may be other elements present
which make the long term risks appear somewhat larger than in Aaa securities.

A - Bonds which are rated A possess many favorable investment attributes
and are to be considered as upper medium grade obligations. Factors giving
security to principal and interest are considered adequate but elements may be
present which suggest a susceptibility to impairment sometime in the future.

Baa - Bonds which are rated Baa are considered as medium grade obligations,
i.e., they are neither highly protected nor poorly secured. Interest payments
and principal security appear adequate for the present but certain protective
elements may be lacking or may be characteristically unreliable over any great
length of time. Such bonds lack outstanding investment characteristics and in
fact have speculative characteristics as well.

Commercial Paper, including Tax Exempt

Prime-1 - Issuers rated Prime-1 (or related supporting institutions) have a
superior capacity for repayment of short-term promissory obligations.
Prime-1 repayment capacity will normally be evidenced by the
following characteristics:

- Leading market positions in well established industries. - High rates of
return on funds employed. - Conservative capitalization structures with moderate
reliance on debt and ample asset protection. - Broad margins in earnings
coverage of fixed financial charges and high internal cash generation. - Well
established access to a range of financial markets and assured sources of
alternate liquidity.

<PAGE>

Short-Term Tax Exempt Notes

MIG-1 - The short-term tax-exempt note rating MIG-1 is the highest
rating assigned by Moody's for notes judged to be the best
quality. Notes with this rating enjoy strong protection from
established cash flows of funds for their servicing or from
established and broad-based access to the market for refinancing,
or both.

MIG-2 - MIG-2 rated notes are of high quality but with margins of
protection not as large as MIG-1.
