     J.P.         MORGAN        PRIME        CASH         MANAGEMENT        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

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

The fund's  yield will vary in response to changes in interest  rates.  How well
the fund's  yield  compares  to the yields of similar  money  market  funds will
depend on the success of the investment process described on page 4.

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

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

Expense example(6)
- --------------------------------------------------------------------------------

The example  below is intended to help you compare the cost of  investing in the

$10,000  initial  investment,  5% return each year,  net expenses for the period
5/17/00 through 2/28/02 and total operating expenses thereafter,  and all shares
sold at the end of each time period.  The example is for  comparison  only;  the
fund's actual return and your actual costs may be higher or lower.

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

     (1) Returns reflect performance of the J.P. Morgan Prime Money Market Fund,
a separate feeder fund investing in the same master  portfolio.  The J.P. Morgan
Prime Money Market Fund commenced  operations on 7/12/93 and returns for periods
prior to 7/31/93  reflect  performance  of The Pierpont  Money Market Fund,  the
predecessor of the J.P.  Morgan Prime Money Market Fund.  These returns  reflect
lower operating expenses than those of the fund.  Therefore,  the fund's returns
would have been lower had it existed during the same period.

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

(3) The fund has a  master/feeder  structure  as described on page 7. This table
    shows  the  fund's  estimated  expenses  and its  estimated  share of master
    portfolio  expenses  for the current year  expressed as a percentage  of the
    fund's estimated average net assets.

(4) The  distribution  plan under Rule 12b-1  (described  on page 7) allows such
    fees to be paid out of the  fund's  assets on an ongoing  basis.  Over time,
    these fees will increase the cost of your  investment  and may cost you more
    than paying other types of sales charges.

(5) Service  organizations  (described on page 5) 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.

(6) Reflects an agreement  dated 5/17/00 by Morgan Guaranty Trust Company of New
    York,  an  affiliate  of J.P.  Morgan to  reimburse  the fund to the  extent
    expenses  (excluding  extraordinary  expenses)  exceed  0.98% of the  fund's
    average daily net assets through 2/28/02.

WHO MAY WANT TO INVEST The fund is 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 fund is 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.




3 | MONEY MARKET MANAGEMENT APPROACH


<PAGE>

- --------------------------------------------------------------------------------
MONEY MARKET INVESTMENT PROCESS
The fund's philosophy,  developed by the fund's advisor,  emphasizes  investment
quality through  in-depth  research of short-term  securities and their issuers.
This allows the 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 fund,  J.P.  Morgan  employs a three-step  process that combines
maturity   determination,   sector  allocation  and  fundamental   research  for
identifying portfolio securities:

[GRAPHIC OMITTED]
J.P. Morgan uses a disciplined process to control the 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 the fund within the permissible 90-day range.  Controlling  weighted average
maturity  allows  the  fund  to  manage  risk,  since  securities  with  shorter
maturities  are typically less sensitive to interest rate shifts than those with
longer maturities.

[GRAPHIC OMITTED]
The fund  invests  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 the
fund's sector  allocation,  with the goal of enhancing current income while also
maintaining diversification across permissible sectors.

[GRAPHIC OMITTED]
The fund selects its securities as described earlier in this prospectus Security
selection  Based on the  results of the firm's  credit  research  and the fund's
maturity  determination  and  sector  allocation,  the  portfolio  managers  and
dedicated  fixed-income  traders  make buy and sell  decisions  according to the
fund's goal and strategy.

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

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

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

o  Maintaining account records for customers

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

o  Responding to inquiries from shareholders

o  Assisting customers with investment procedures


ACCOUNT AND TRANSACTION POLICIES
Business days and NAV calculations The fund's regular business days are the same
as those of the New York  Stock  Exchange.  The 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
the fund must be received by 5:00 p.m.

     For the  purchase to be  effective  and  dividends to be earned on the same
day,  immediately  available  funds must be received by the fund by its close of
business on that day. Service organizations will be responsible for transmitting
accepted  orders and payments to the fund by 5:00 p.m. The fund has the right to
suspend  redemption  of shares as  permitted  by law and to postpone  payment of
proceeds for up to seven days.


<PAGE>

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

Redemption  orders  for the fund  received  by will be 5:00  p.m.  will  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.

Redemption  in Kind The fund  reserves  the  right to make  redemptions  of over
$250,000 in securities rather than in cash.

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

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

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


5 | YOUR INVESTMENT



<PAGE>


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

TAX CONSIDERATIONS
In general,  selling  shares,  exchanging  shares,  and receiving  distributions
(whether  reinvested or taken in cash) are all taxable events.  Income dividends
from the fund typically creates ordinary income.

Short-term capital gains                          Ordinary income
distributions

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

number will be subject to backup withholding for taxes.

FUND DETAILS
- --------------------------------------------------------------------------------
MASTER/FEEDER STRUCTURE
As  noted  earlier,  the  fund is a  "feeder"  fund  that  invests  in a  master
portfolio.  (Except where indicated, this prospectus uses the term "the fund" to
mean the feeder fund and its master portfolio taken together.)

The 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.

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

MANAGEMENT AND ADMINISTRATION
The feeder  fund  described  in this  prospectus  and its  corresponding  master
portfolio 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, subject to the expense reimbursements described earlier in this
prospectus, receives the following fees for investment advisory and other
services:

GENERAL

         This  Statement  of  Additional  Information  relates  only to the J.P.
Morgan Prime Cash Management  Fund (the "Fund").  The 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  Fund,  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 the Fund
and provides additional  information with respect to the Fund and should be read
in  conjunction   with  the  Fund's  current   Prospectus  (the   "Prospectus").
Capitalized  terms not otherwise  defined  herein have the meanings  accorded to
them in the  Prospectus.  The Fund'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,  the Fund seeks to achieve its investment  objective by
investing all of its investable assets in a Master Portfolio (the  "Portfolio"),
an open-end management  investment company having the same investment  objective
as the Fund. The Fund invests in the Portfolio through a two-tier  master-feeder
investment  fund  structure.  See  "Special  Information  Concerning  Investment
Structure."

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

         Investments  in the  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 the Fund
are not federally  insured by the Federal  Deposit  Insurance  Corporation,  the
Federal Reserve Board, or any other  governmental  agency.  An investment in the
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 the Fund and the policies to be employed to achieve the
objective  by the  Portfolio  as set forth  herein  and in the  Prospectus.  The
investment objectives of the Fund and the investment objectives of its Portfolio
are identical.  Accordingly,  references below to the Portfolio also include the
Fund;  similarly,  references to the Fund also include the Portfolio  unless the
context requires otherwise.

         The 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 Fund's  investment
objective is to maximize  current income  consistent  with the  preservation  of
capital and same-day  liquidity.  The 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 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."

Money Market Instruments

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

     U.S. Treasury Securities.  The Fund 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  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,  the 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 the 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  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 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 Fund  will  not  invest  in
obligations  for which the Advisor,  or any of its  affiliated  persons,  is the
ultimate  obligor or accepting  bank. The 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 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 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  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 Fund to be liquid  because they are payable upon demand.  The
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  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  principal  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 the 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.  The Fund may enter into repurchase  agreements
with brokers,  dealers or banks that meet the credit guidelines  approved by the
Fund's  Trustees.  In a repurchase  agreement,  the 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 the Fund to the seller.  The
period of these repurchase  agreements will usually be short,  from overnight to
one week, and at no time will the 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 Fund 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 Fund in
each  agreement plus accrued  interest,  and the Fund will make payment for such
securities  only upon physical  delivery or upon evidence of book entry transfer
to the account of the Custodian.  The 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,  the 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 the Fund may be
delayed or limited.

         The 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 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 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 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.  The Fund 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 the Fund until  settlement  takes place. At the time the
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,  the 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,  the Fund will meet its
obligations  from  maturities or sales of the securities  held in the segregated
account  and/or from cash flow.  If the 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, the Fund may be  disadvantaged if the other party to
the transactions defaults.

         Investment Company Securities. Securities of other investment companies
may be acquired by the Fund and the Portfolio 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 the 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 the Fund,  provided  however,  that the Fund may invest
all of its investable assets in an open-end investment company that has the same
investment  objective as the Fund (its  Portfolio).  As a shareholder of another
investment  company,  the  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 the Fund or Portfolio  bears directly in connection with its
own operations.
         Reverse  Repurchase  Agreements.   The  Fund  may  enter  into  reverse
repurchase  agreements.  In a reverse  repurchase  agreement,  the 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 the Fund to be  magnified.
The Fund will  invest  the  proceeds  of  borrowings  under  reverse  repurchase
agreements. In addition, except for liquidity purposes, the 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.  The Fund will
not invest the  proceeds of a reverse  repurchase  agreement  for a period which
exceeds  the  duration  of the  reverse  repurchase  agreement.  The  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 the
Fund's limitations on reverse repurchase agreements and bank borrowings.

         Loans  of  Portfolio  Securities.   Subject  to  applicable  investment
restrictions, the Fund is permitted to lend its securities in an amount up to 33
1/3% of the value of the Fund's net assets.  The Fund 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  Fund  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 the Fund and its  respective
investors. The Fund may pay reasonable finders' and custodial fees in connection
with a loan.  In addition,  the 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 the Fund with
respect to borrowers of its portfolio securities are similar to the risks to the
Fund  with  respect  to  sellers  in  repurchase  agreement  transactions.   See
"Repurchase  Agreements".  The Fund will not lend its securities to any officer,
Trustee, Member of the Advisory Board, Director,  employee or other affiliate of
the  Fund,  the  Advisor  or the  Distributor,  unless  otherwise  permitted  by
applicable law.

         Illiquid   Investments,   Privately  Placed  and  Certain  Unregistered
Securities.  The Fund may invest in privately placed,  restricted,  Rule 144A or
other  unregistered  securities.  The Fund may not acquire any illiquid holdings
if, as a result  thereof,  more than 10% of the Fund's  net  assets  would be in
illiquid  investments.  Subject  to  this  fundamental  policy  limitation,  the
Portfolio 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  Portfolio.  The price  the  Portfolio  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 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,  the 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,  the 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,  the  Fund  might  obtain  a less
favorable price than prevailed when it decided to sell.

         Synthetic  Instruments.  The  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

         In order to achieve its investment  objective and maintain a stable net
asset value,  the 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 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,  as defined by Rule 2a-7 under the 1940 Act; and
(ii) 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.

INVESTMENT RESTRICTIONS

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

     The  investment  restrictions  below  have been  adopted  by the Trust with
respect to the Fund and by the 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  the Fund is requested to vote on a change in
the fundamental investment restrictions of the Portfolio,  the Trust will hold a
meeting of Fund shareholders and will cast its votes as instructed by the Fund's
shareholders.

         The Fund and the Portfolio:

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 Fund and the Portfolio and
may be changed by their  Trustees.  These  non-fundamental  investment  policies
require that the Fund and the Portfolio:

(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;

(iv) May not borrow  money,  except from banks for  extraordinary  or  emergency
     purposes  and then only in  amounts  not to exceed  10% of the value of the
     Fund's  total  assets,  taken  at  cost,  at the  time of  such  borrowing.
     Mortgage,  pledge,  or hypothecate any assets except in connection with any
     such  borrowing and in amounts not to exceed 10% of the value of the Fund's
     net  assets  at the  time of such  borrowing.  The Fund  will not  purchase
     securities while borrowings exceed 5% of the Fund's total assets; provided,
     however,  that the Fund may increase its interest in an open-end management
     investment  company with the same investment  objective and restrictions as
     the Fund while such borrowings are outstanding. This borrowing provision is
     included  to  facilitate  the orderly  sale of  portfolio  securities,  for
     example, in the event of abnormally heavy redemption  requests,  and is not
     for  investment   purposes  and  shall  not  apply  to  reverse  repurchase
     agreements.

         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.

(*)      Includes the  Portfolios  and 17 other  portfolios  (collectively,  the
         "Master Portfolios") for which JPMIM acts as investment advisor.

     (**) During 1999,  Pierpont  Group,  Inc. paid Mr.  Healey,  in his role as
Chairman  of  Pierpont  Group,  Inc.,  compensation  in the amount of  $153,800,
contributed  $23,100  to a  defined  contribution  plan on his  behalf  and paid
$17,300 in insurance premiums for his benefit.

     (***) 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.  The Portfolio 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  Portfolio  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 Portfolio have agreed to
pay Pierpont Group, Inc. a fee in an amount representing its reasonable costs in
performing  these  services  to the  Trust,  the  Portfolio  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 the  Fund and
Portfolio during the indicated fiscal periods are set forth below:

     The  Portfolio  -- For the fiscal years ended  November 30, 1997,  1998 and
1999: $143,027, $173,032 and $228,328, respectively.

Advisory Board

         The Trustees determined as of January 26, 2000 to establish an advisory
board and appoint four members  ("Members of the Advisory Board") thereto.  Each
Member  serves at the pleasure of the Trustees.  The Advisory  Board is distinct
from  the  Trustees  and  provides  advice  to the  Trustees  as to  investment,
management and operations of the Trust; but has no power to vote upon any matter
put to a vote of the Trustees.  The Advisory Board and the Members  thereof also
serve  each of the  Trusts and the  Master  Portfolios.  It is also the  current
intention  of the  Trustees  that the  Members  of the  Advisory  Board  will be
proposed at the next  shareholders'  meeting,  expected to be held within a year
from the date  hereof,  for  election  as Trustees of each of the Trusts and the
Master Portfolios. The creation of the Advisory Board and the appointment of the
Members  thereof was  designed so that the Board of Trustees  will  continuously
have  available to it persons able to assume the duties of Trustees and be fully
familiar  with the  business  and  affairs  of each of the Trusts and the Master
Portfolios,  in  anticipation  of the current  Trustees  reaching the  mandatory
retirement  age of seventy.  Each Member of the Advisory Board is paid an annual
fee of $75,000 for serving in this  capacity  for the Trust,  each of the Master
Portfolios,  the J.P.  Morgan  Funds  and the J.P.  Morgan  Series  Trust and is
reimbursed for expenses incurred in connection for such service.  The Members of
the Advisory Board may hold various directorships  unrelated to these funds. The
mailing  address of the Members of the  Advisory  Board is c/o  Pierpont  Group,
Inc.,  461 Fifth  Avenue,  New York,  New York  10017.  Their  names,  principal
occupations during the past five years and dates of birth are set forth below:

CODES OF ETHICS

         The Trust and the Advisor have adopted codes of ethics pursuant to Rule
17j-1 under the 1940 Act. Each of these codes permits  personnel subject to such
code to invest in securities, including securities that may be purchased or held
by the Portfolio. Such purchases,  however, are subject to procedures reasonably
necessary to prevent a fraud or deceit on the Trust.

INVESTMENT ADVISOR

         The Fund has not retained the services of an investment advisor because
the Fund seeks to achieve  its  investment  objective  by  investing  all of its
investable  assets  in  the  Portfolio.   Subject  to  the  supervision  of  the
Portfolio's  Trustees,  the Advisor makes the 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 the 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  advisor  under  the  Investment
Advisors  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 $376 billion.

         J.P.  Morgan has a long history of service as advisor,  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 375  research
analysts, capital market researchers, portfolio managers and traders and has one
of the largest  research staffs in the money management  industry.  The Advisor
has investment  management  divisions  located  in New  York,  London,  Tokyo,
Frankfurt, and Singapore to cover companies, industries and countries on site.

         The investment  advisory services the Advisor provides to the Portfolio
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  Portfolio.  Such accounts are supervised by employees of the Advisor who
may also be acting in  similar  capacities  for the  Portfolio.  See  "Portfolio
Transactions."

     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. Morgan is also a wholly
owned subsidiary of J.P. Morgan, which is a bank holding company organized under
the laws of the State of Delaware.

     The  Portfolio  is managed by  employees  of the Advisor who, in acting for
their  customers,  including  the  Portfolio,  do not discuss  their  investment
decisions with any personnel of J.P. Morgan with any of its affiliated  persons,
with the exception of certain  other  investment  management  affiliates of J.P.
Morgan or broker dealer affiliates of J.P. Morgan which execute  transactions on
behalf of the Fund.

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

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

     The  Portfolio  -- For the fiscal years ended  November 30, 1997,  1998 and
1999: $5,063,662, $7,199,733 and $13,226,942, respectively.

         The  Investment  Advisory  Agreement  provides that it 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.   The  Investment   Advisory   Agreement  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."

     Under  separate  agreements,   Morgan  provides  certain  financial,   fund
accounting  and  administrative  services  to the  Trust and the  Portfolio  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 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 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 the
Fund 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 Members of
the Advisor Board" 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  Portfolio
dated  August 1,  1996,  FDI also  serves  as the  Trust's  and the  Portfolio's
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 Portfolio,  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  Portfolio,  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 investors;
and (vi) maintains related books and records.

         For its services under the Co-Administration  Agreements,  the Fund and
Portfolio have 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 the Fund or  Portfolio  is based on the ratio of its net assets to
the  aggregate net assets of the Trust,  the Master  Portfolio and certain other
investment companies subject to similar agreements with FDI.

         The  table  below  sets  forth  the  administrative  fees  paid  by the
Portfolio to FDI for the fiscal periods indicated.

     The  Portfolio  -- For the fiscal years ended  November 30, 1997,  1998 and
1999: $96,662, $115,137 and $147,749, respectively.

SERVICES AGENT

         The Trust,  on behalf of the Fund,  and the Portfolio 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 the Fund and the Portfolio.  The Services Agreements may be
terminated at any time,  without  penalty,  by the Trustees or Morgan,  not more
than 60 days' nor less than 30 days' written notice to the other party.

         Under the Services  Agreements,  the Fund and the Portfolio have 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 the Fund and Portfolio is determined by the proportionate  share that
its net assets bear to the total net assets of the Trust, the Master  Portfolio,
the other investors in the Master  Portfolio for which Morgan  provides  similar
services and J.P. Morgan Series Trust.

         The table below sets forth for the Portfolio the fees paid to Morgan as
Services Agent. See the Prospectus and below for applicable expense limitations.

     The  Portfolio  -- For the fiscal years ended  November 30, 1997,  1998 and
1999: $1,256,131, $1,788,454 and $3,127,566, respectively.

CUSTODIAN AND TRANSFER AGENT

         The Bank of New York  ("BONY"),  One Wall  Street,  New York,  New York
10286,  serves as the Trust's  and each of the  Portfolio's  custodian  and fund
accounting agent.  Pursuant to the Custodian  Contract,  BONY is responsible for
holding portfolio  securities and cash, and maintaining the books of account and
records of portfolio transactions.

         State  Street Bank and Trust  Company  ("State  Street"),  225 Franklin
Street, Boston,  Massachusetts 02110, serves as the Fund's transfer and dividend
disbursing agent. 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.

SERVICE ORGANIZATIONS

         On April 6, 2000,  the  Trust,  on behalf of the Fund,  has  approved a
service plan (the "Plan") with respect to the shares which  authorizes  the Fund
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 the 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 the 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 the 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 advisors 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  advisors
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 6, 2000.
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 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 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 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.

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 6, 2000,
the Trustees approved such a plan (the "Distribution  Plan") with respect to the
Fund  pursuant to which the Fund pays for  distributing  its shares at an annual
rate not to exceed  0.50% 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  the  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 Fund's
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  Portfolio  are
PricewaterhouseCoopers  LLP,  1177 Avenue of the  Americas,  New York,  New York
10036.  PricewaterhouseCoopers  LLP  conducts an annual  audit of the  financial
statements  of the Fund and the  Portfolio,  assists in the  preparation  and/or
review of the Fund's and the  Portfolio's  federal and state  income tax returns
and consults  with the Fund and the  Portfolio 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,   Advisory  Board  Memebers  and  Officers,"   "Investment  Advisor,"
"Co-Administrator",  "Distributor," "Services Agent" and "Shareholder Servicing"
above,  the Fund and the  Portfolio  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 and Members of the Advisory
Board,  costs associated with their  registration fees under federal  securities
laws, and extraordinary  expenses  applicable to the Fund or the Portfolio.  For
the Fund, 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  Portfolio,  such expenses also include  custodian  fees. For additional
information regarding reimbursements, see the Prospectus.

         J.P.  Morgan has agreed that it will  reimburse the Fund until February
28, 2002 to the extent necessary to maintain the Fund's total operating expenses
(which  include  expenses of the Fund and the  Portfolio)  at the annual rate of
0.98% of the  Fund's  average  daily  net  assets.  This  limit  does not  cover
extraordinary expenses.

PURCHASE OF SHARES

         Additional Minimum Balance  Information.  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.

         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 the 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
the Fund may make transactions in shares of the 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 the
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.

         The 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  Portfolio.  In  addition,  securities
accepted in payment  for shares  must:  (i) meet the  investment  objective  and
policies of the  acquiring  Fund's  Portfolio;  (ii) be acquired by the Fund for
investment  and not for resale (other than for resale to the Fund's  Portfolio);
and (iii) be liquid securities which are not restricted as to transfer either by
law or liquidity of market.  The 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 Fund should be aware that the Fund attempts
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 the Fund and the Portfolio determines that it
would be detrimental to the best interest of the remaining  shareholders  of the
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.

         Further  Redemption   Information.   Investors  should  be  aware  that
redemptions  from the 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 the Fund, and the Portfolio  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 the 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
the 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.  The Fund generally  intends to pay  redemption  proceeds in cash,
however,  since it reserves the right at its sole  discretion to pay redemptions
over $250,000 in-kind as a portfolio of representative securities rather than in
cash, the Fund reserves the right to deny an exchange  request in excess of that
amount. See "Redemption of Shares".  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

         The 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

         The Fund  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 Fund and the Portfolio  would expect to close for purchases and  redemptions
an hour in advance of the end of trading in the money markets.  The Fund and the
Portfolio 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 Bond Market  Association  ("BMA")  recommends
that the  securities  market close early,  the Fund  reserves the right to cease
accepting  purchase and  redemption  orders for same  business day credit at the
time BMA recommends  that the securities  market close.  On days the Fund closes
early,  purchase and  redemption  orders  received after the Fund closes will be
credited the next  business day. The days on which net asset value is determined
are the Fund's business days.

         The net  asset  value of the Fund is equal to the  value of the  Fund's
investment in the 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
Portfolio in valuing its assets.

         The Portfolio's  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  the 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 the
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 Fund. See "Taxes."

PERFORMANCE DATA

         From time to time,  the Fund 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 Fund 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 Fund is that of the J.P.  Morgan  Prime Money  Market Fund (the "Prime Money
Market Fund"), a separate feeder fund investing in the same master portfolio.

         Yield Quotations.  As required by regulations of the SEC, current yield
for the Fund 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
the Fund is computed by  annualizing  the  seven-day  return with all  dividends
reinvested in additional Fund shares.

         The historical  performance  information shown below reflects operating
expenses  which were lower than those of the Fund. The fund's returns would have
been lower had it existed during the same period.

         Below is set forth historical return information for the Fund's related
feeder fund, the Prime Money Market Fund and prior to July 30, 1993, predecessor
fund, The Pierpont Money Market Fund for the periods indicated:

     Prime Money  Market Fund (and prior to July 30, 1993,  The  Pierpont  Money
Market Fund)  (11/30/99):  Average annual total return, 1 year:  4.88%;  average
annual total return,  5 years:  5.33%;  average  annual total return,  10 years:
5.14%;  aggregate total return, 1 year: 4.88%;  aggregate total return, 5 years:
29.63%; aggregate total return, 10 years: 65.07%.

         Aggregate total returns,  reflecting the cumulative  percentage  change
over a measuring period, may also be calculated.

         General.  The Fund's  performance will vary from time to time depending
upon market  conditions,  the  composition of the  Portfolio,  and its operating
expenses. Consequently, any given performance quotation should not be considered
representative of the 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 the  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 Fund's shares, including appropriate market indices 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 Fund 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 the Fund; (5)
descriptions  of  investment  strategies  for  the  Fund;  (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  Fund;  (7)  comparisons  of  investment  products
(including  the  Fund)  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 Fund  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 the Fund.

PORTFOLIO TRANSACTIONS

     The Advisor  places orders for the Portfolio 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 Portfolio. 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 Portfolio will be undertaken principally
to accomplish the Portfolio's objective in relation to expected movements in the
general level of interest rates. The Portfolio may engage in short-term  trading
consistent with their objectives.

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

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

         Subject to the  overriding  objective  of obtaining  best  execution of
orders,  the  Advisor  may  allocate  a  portion  of the  Portfolio's  brokerage
transactions  to  affiliates  of  the  Advisor.  Under  the  1940  Act,  persons
affiliated  with the Portfolio and persons who are affiliated  with such persons
are prohibited  from dealing with the Portfolio as principal in the purchase and
sale of  securities  unless a permissive  order  allowing such  transactions  is
obtained from the SEC. However, affiliated persons of the Portfolio may serve as
its broker in listed or  over-the-counter  transactions  conducted  on an agency
basis provided that, among other things, the fee or commission  received by such
affiliated  broker is  reasonable  and fair  compared  to the fee or  commission
received by non-affiliated  brokers in connection with comparable  transactions.
In addition,  the Portfolio may not purchase  securities during the existence of
any  underwriting  syndicate for such securities of which Morgan or an affiliate
is a member or in a private  placement in which Morgan or an affiliate serves as
placement agent except  pursuant to procedures  adopted by the Board of Trustees
of the  Portfolio  that  either  comply  with  rules  adopted by the SEC or with
interpretations of the SEC's staff.

         On those  occasions  when the Advisor  deems the  purchase or sale of a
security to be in the best interests of the 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 Portfolio. In some instances,  this
procedure might adversely affect the Portfolio.

MASSACHUSETTS TRUST

         The  Trust  is  a  trust  fund  of  the  type   commonly   known  as  a
"Massachusetts  business  trust" of which the 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  May 12,  1997,  the name of The Money Market  Portfolio  was
changed to The Prime Money Market Portfolio. 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 the  Fund  and that  every
written agreement,  obligation,  instrument or undertaking made on behalf of the
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 the Fund. However, upon payment of such liability,  the shareholder
will be  entitled to  reimbursement  from the  general  assets of the 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 Fund.

         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, Member of the Advisory Board, officer, employee or
agent  of the  Fund is  liable  to the  Fund or to a  shareholder,  and  that no
Trustee, Member of the Advisory Board, officer,  employee, or agent is liable to
any third  persons in  connection  with the affairs of the 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 the Fund. With
the exceptions stated, the Trust's Declaration of Trust provides that a Trustee,
Member of the  Advisory  Board,  officer,  employee,  or agent is entitled to be
indemnified against all liability in connection with the affairs of the 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 the 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 the Fund (or in the assets of other series,  if applicable).
Each share represents an equal proportional interest in the Fund with each other
share.  Upon liquidation of the Fund,  holders are entitled to share pro rata in
the net assets of the Fund available for distribution to such shareholders.  See
"Massachusetts  Trust."  Shares of the 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 22 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,  the Fund is an open-end management  investment company
which  seeks  to  achieve  its  investment  objective  by  investing  all of its
investable  assets  in a 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 the Fund, the 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) 766-7722.

         The Trust may withdraw the investment of the Fund from the 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 the Fund's Prospectus.

         Certain changes in the Portfolio's  fundamental  investment policies or
restrictions,  or a failure by the 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 the 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 affect 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  Statement  of  Additional  Information.
These  laws  and   regulations   are  subject  to  change  by   legislative   or
administrative action, possibly on a retroactive basis.

         The Fund  intends  to  qualify  and  remain  qualified  as a  regulated
investment  company under  Subchapter M of the Code.  As a regulated  investment
company, the 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,  the  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,  the 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. The 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 the
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  Fund as
ordinary  income whether such  distributions  are taken in cash or reinvested in
additional shares.  Distributions to corporate  shareholders of the Fund 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 the 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 the 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 option 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 the 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 the
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.  Investors should thus consider the consequences
of  purchasing  shares in a Fund  shortly  before  the Fund  declares  a sizable
dividend distribution.

         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. Additionally,  any loss realized on a redemption or
exchange  of shares of the 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.  Investors  are urged to consult  their tax  advisors  concerning  the
limitations on the deductibility of capital losses.

         If a correct and  certified  taxpayer  identification  number is not on
file, the Fund is required,  subject to certain  exemptions,  to withhold 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,  the 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 (or any successor form) is
provided.  Transfers by gift of shares of the 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.  The 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 the 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 the Fund is liable for any
income or franchise tax in The Commonwealth of Massachusetts,  provided that the
Fund continues to qualify as a regulated  investment  company under Subchapter M
of the Code.  The  Portfolio is organized as a New York trust.  The Portfolio is
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 the
Fund in the  Portfolio  does not cause the Fund to be liable  for any  income or
franchise tax in the State of New York.

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.

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.

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.

     -------- 1 Mr.  Healey is an  "interested  person"  (as defined in the 1940
Act) of the Trust.
