LETTER TO THE SHAREHOLDERS OF THE J.P. MORGAN INSTITUTIONAL BOND FUND

June 1, 1998

Dear Shareholder:

The six months ending April 30, 1998 was a good one for bonds and for your fund.
The J.P. Morgan Institutional Bond Fund provided a solid total return of 3.60%
for the six months under review. For the reporting period, the fund's
performance was slightly behind the 3.67% return for its benchmark, the Salomon
Brothers Broad Investment Grade Bond Index. However, the fund outperformed its
competitors, as measured by the Lipper Intermediate Investment Grade Debt Funds
Average, which returned 3.21% for the period.

The fund's net asset value decreased from $10.01 per share on October 31, 
1997 to $9.97 per share at the end of the reporting period, after paying 
approximately $0.33 per share in dividends from ordinary income and 
approximately $0.07 per share in dividends from capital gains.The fund's net 
assets stood at $908.3 million at the end of the reporting period. The net 
assets of the U.S. Fixed Income Portfolio, in which the fund invests, totaled 
approximately $1.2 billion on April 30, 1998. 

The report that follows includes a portfolio manager Q&A with William G.
Tennille, a member of our portfolio management team. This interview is designed
to answer commonly asked questions about the fund, elaborate on what happened
during the reporting period, and provide an outlook for the months ahead.

As chairman and president of Asset Management Services, we appreciate your 
investment in the fund. If you have any comments or questions, please call 
your Morgan representative or J.P. Morgan Funds Services at (800) 766-7722.

Sincerely yours,

/s/ Ramon de Oliveira                     /s/ Keith M. Schappert

FUND PERFORMANCE

EXAMINING PERFORMANCE
One way to look at performance is to review a fund's average annual total
return. This figure takes the fund's actual (or cumulative) return and shows
what would have happened if the fund had achieved that return by performing at a
constant rate each year. Average annual total returns represent the average
yearly change of a fund's value over various time periods, typically one, five,
or ten years (or since inception). Total returns for periods of less than one
year are not annualized and provide a picture of how a fund has performed over
the short term.

PORTFOLIO MANAGER Q&A

[PHOTO]

Following is an interview with WILLIAM G. TENNILLE, who is a member of the
portfolio management team for the U.S. Fixed Income Portfolio, in which the fund
invests. Bill joined Morgan in 1992 and has extensive experience across a broad
range of markets, including mortgage securities and derivatives. This interview
was conducted on May 19, 1997 and reflects Bill's views on that date.

EARLY IN THE FOURTH QUARTER OF 1997, THE EAST ASIAN MARKET TURMOIL WAS ERUPTING.
CAN YOU GIVE US A FOLLOW-UP ON THAT SITUATION TO DATE?

WGT:  Despite a brief lull in the East Asian crisis late last year, the
situation is pretty much the same. The Asian currency problems effectively ended
an extended period of declining volatility, but they also had some far-reaching,
indirect effects as well. 

When the Asian crisis erupted, everybody put their money into U.S. bonds, which
in turn, drove interest rates in the U.S. down. Then, two things happened.
Because rates in the U.S. dropped significantly, the amount of corporate
issuance surged. This surge continued for two or three months, and was quite
strong since many companies were scrambling to borrow more cheaply than they had
a few years ago. At any rate, corporate spreads widened due to the increase in
supply.

The second effect was sort of a parallel event in the mortgage sector. As a
result of interest rates declining, people could suddenly refinance their
mortgages at a lower rate. But as anyone who owns a home knows, there's a lag
between the decision to refinance and the actual prepayment. So although it took
two or three months for the situation to catch up, so to speak, once it hit,
mortgage prepayments were pouring in. This of course hurt performance in the
mortgage sector.

PLEASE ELABORATE ON HOW THE ASIAN SITUATION HAS SPECIFICALLY AFFECTED THE
PORTFOLIO'S PERFORMANCE.

WGT:  If you look at the situation, we watched two sectors -- corporates and
mortgages -- affected by the Asian crisis, however indirectly. There was
somewhat of a lag before we actually saw the effects, particularly with
mortgages. There was also a slight lag with corporates, maybe a month or so.
These factors hurt performance in the portfolio for a short period of time over
the last few months, but not overly so. And we've definitely bounced back since
the beginning of the year. The fact that the market rallied aided us in terms of
performance, despite the Asian situation. Fortunately, we didn't have a large
amount of holdings that would have been directly adversely affected. One of the
ways we managed the situation was to do some exchanges out of some Asian paper
into the new Korean sovereign issues, which are a lot more liquid and in effect,
safer, in the event of another currency crisis such as this.


                                                                               3
<PAGE>

SINCE WE LAST SPOKE, IT SEEMS YOU'VE CHOSEN TO INCREASE THE PORTFOLIO'S
WEIGHTINGS IN BOTH FOREIGN GOVERNMENT BONDS AND SHORT-TERM ASSETS. WHY? IS THIS
A SIGNIFICANT MOVE WITHIN THE CONTEXT OF THE PORTFOLIO'S STRATEGY?

WGT: Actually, it was. We purchased the equivalent of T-bills from Germany and
France, as our goal was to capitalize on an opportunity to earn through AAA
securities. These securities earn roughly 80 basis points over Treasuries. So we
decided to buy foreign--in this case, German and French--T-bills, and hedged
them back to the dollar. In short, there's no currency risk, but it's a
substantially higher yield than what we could have gotten in the U.S. market.
And while the increase in weightings is somewhat significant in the context of
our overall allocation for the fund, it would not seriously impact the portfolio
either negatively or positively.

Another tactic we used was to selectively sell 30-year bonds and buy five-,
seven- and ten-year bonds, simply because as the spreads widened, the difference
in yield between the longer term issues and the shorter term issues disappeared
a bit, and if we're just trying to add spread to the portfolio, it's a lot less
risky to do it in a seven-year bond than in a 30-year bond.

SINCE DURATION IS OFTEN INSTRUMENTAL IN ACHIEVING A PORTFOLIO'S PERFORMANCE,
WOULD YOU DISCUSS HOW, IF AT ALL, THE PORTFOLIO'S CURRENT POSITION HAS
AFFECTED/DRIVEN PERFORMANCE? INVESTORS MAY BENEFIT FROM A BRIEF REVIEW OF HOW
YOU USE DURATION TO GENERATE RETURNS.

WGT:  Our overall philosophy is to spread risk over as many factors as we
possibly can. It is for this reason we are actually not big duration players.
Our goal is to add maybe 20 basis points of return over a year through duration.
This is because we do not believe in making big bets when it comes to duration.
If you make a huge duration bet one way and the market goes the other way, it's
tragically costly. So we're not big bettors in that regard. The fund follows the
Salomon Brothers Broad Investment Grade Bond Index, and we don't take positions
greater than one-year longer or one-year shorter than that of the benchmark.
It's a pretty set guideline that we don't often stray from. 

WOULD YOU OFFER OUR SHAREHOLDERS YOUR OUTLOOK OR FORECAST FOR THE SECOND HALF OF
1998?

WGT:  At the end of 1997, we saw the Asian crisis go on a lot longer than many
of us expected, which meant the Asian companies and countries who used to buy
our exports have essentially stopped doing so. They're concerned with exporting
now, for the most part. And, they've been forced to cut prices, which means that
nobody can raise prices on anything it seems, worldwide. This will likely
continue for a while.

Logically, earnings have started to tail off a bit. For a while everyone
expected the Federal Reserve to tighten in order to slow the economy down, but
it looks like that won't be necessary. The Asian situation, looked at in terms
of prices, collectively has probably made any such action by the Fed
unnecessary.

If things continue along the same line as they have over the last seven or eight
months, we're forecasting a decline in GDP. In that vein, we believe a
tightening by the Fed is again, unlikely. The other significant ingredient in
all of this is that Treasury issuance has declined substantially. This is
primarily due to the fact that we now have a budget surplus--there just isn't
the need to raise as much money, and therefore Treasury issuance has declined
substantially.

Having said that, interest rates are still quite low. That's going to affect
returns to a certain extent. But considering the fact that there are fewer bonds
out there and more people trying to buy them, we expect performance to be good.
It's actually a good combination of events. Yes, yields are low, but as long as
the supply remains low too and there's a decent amount of money out there
available for the fixed income markets, and, as more investors speculate about
the stock market--fearing it will begin to go down--more investors will look
toward bonds for more security. Considering the forces of supply and demand, we
anticipate that the bond market should do well, even considering further Asian
shocks, which seem inevitable.

J.P. MORGAN INSTITUTIONAL BOND FUND
NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
APRIL 30, 1998
- --------------------------------------------------------------------------------
 
1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
The J.P. Morgan Institutional Bond Fund (the "fund") is a separate series of the
J.P. Morgan Institutional Funds, a Massachusetts business trust (the "trust")
which was organized on November 4, 1992. The trust is registered under the
Investment Company Act of 1940, as amended, as an open-end management investment
company. The fund commenced operations on July 26, 1993. Prior to January 1,
1998, the trust's and the fund's names were The JPM Institutional Funds and The
JPM Institutional Bond Fund, respectively.
 
The fund invests all of its investable assets in The U.S. Fixed Income Portfolio
(the "portfolio"), a diversified open-end management investment company having
the same investment objective as the fund. The value of such investment included
in the Statement of Assets and Liabilities reflects the fund's proportionate
interest in the net assets of the portfolio (78% at April 30, 1998). The
performance of the fund is directly affected by the performance of the
portfolio. The financial statements of the portfolio, including the Schedule of
Investments, are included elsewhere in this report and should be read in
conjunction with the fund's financial statements.
 
The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures. Actual amounts could differ from
those estimates. The following is a summary of the significant accounting
policies of the fund:
 
   a) Valuation of securities by the portfolio is discussed in Note 1a of the
      portfolio's Notes to Financial Statements which are included elsewhere in
      this report.
 
   b) The fund records its share of net investment income, realized and
      unrealized gain and loss and adjusts its investment in the portfolio each
      day. All the net investment income and realized and unrealized gain and
      loss of the portfolio is allocated pro rata among the fund and other
      investors in the portfolio at the time of such determination.
 
   c) Substantially all the fund's net investment income is declared as
      dividends daily and paid monthly. Distributions to shareholders of net
      realized capital gains, if any, are declared and paid annually.
 
   d) The fund incurred organization expenses in the amount of $49,925. Morgan
      Guaranty Trust Company of New York ("Morgan") has paid the organization
      expenses of the fund. The fund has reimbursed Morgan for these costs which
      are being deferred and amortized on a straight-line basis over a period
      not to exceed five years beginning with the commencement of operations of
      the fund.
 
   e) Expenses incurred by the trust with respect to any two or more funds in
      the trust are allocated in proportion to the net assets of each fund in
      the trust, except where allocations of direct expenses to each fund can
      otherwise be made fairly. Expenses directly attributable to a fund are
      charged to that fund.
 
   f ) The fund is treated as a separate entity for federal income tax purposes.
       The fund intends to comply with the provisions of the Internal Revenue
       Code of 1986, as amended, applicable to regulated investment companies
       and to distribute sustantially all of its income, including net realized
       capital gains, if any, within the prescribed time periods. Accordingly,
       no provision for federal income or excise tax is necessary.

2. TRANSACTIONS WITH AFFILIATES
 
   a) The trust, on behalf of the fund, has retained Funds Distributor, Inc.
      ("FDI"), a registered broker-dealer, to serve as the co-administrator and
      distributor for the fund. Under a Co-Administration Agreement between FDI
      and the trust, on behalf of the fund, FDI provides administrative services
      necessary for the operations of the fund, furnishes office space and
      facilities required for conducting the business of the fund and pays the
      compensation of the fund's officers affiliated with FDI. The fund has
      agreed to pay FDI fees equal to its allocable share of an annual
      complex-wide charge of $425,000 plus FDI's out-of-pocket expenses. The
      amount allocable to the fund is based on the ratio of the fund's net
      assets to the aggregate net assets of the trust and certain other
      investment companies subject to similar agreements with FDI. For the six
      months ended April 30, 1998, the fee for these services amounted to
      $10,941.
 
   b) The trust, on behalf of the fund, has an Administrative Services Agreement
      (the "Services Agreement") with Morgan under which Morgan is responsible
      for certain aspects of the administration and operation of the fund. Under
      the Services Agreement, the fund had agreed to pay Morgan a fee equal to
      its allocable share of an annual complex-wide charge. This charge is
      calculated based on the aggregate average daily net assets of the
      portfolio and the other portfolios in which the trust and J.P. Morgan
      Funds (formerly The JPM Pierpont Funds) invest (the "master portfolios")
      and J.P. Morgan Series Trust (formerly JPM Series Trust) in accordance
      with the following annual schedule: 0.09% on 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 is
      determined by the proportionate share that its net assets bear to the net
      assets of the trust, the master portfolios, other investors in the master
      portfolios for which Morgan provides similar services, and J.P. Morgan
      Series Trust. For the six months ended April 30, 1998, the fee for these
      services amounted to $132,771.
 
      In addition, Morgan has agreed to reimburse the fund to the extent
      necessary to maintain the total operating expenses of the fund, including
      the expenses allocated to the fund from the portfolio, at no more than
      0.50% of the average daily net assets of the fund through January 31,
      1999. For the six months ended April 30, 1998, no reimbursement was
      necessary.
 
   c) The trust, on behalf of the fund, has a Shareholder Servicing Agreement
      with Morgan to provide account administration and personal account
      maintenance service to fund shareholders. The agreement provides for the
      fund to pay Morgan a fee for these services which is computed daily and
      paid monthly at an annual rate of 0.075% of the average daily net assets
      of the fund. For the six months ended April 30, 1998, the fee for these
      services amounted to $333,201.
 
   d) The trust, on behalf of the Fund, has a Fund Services Agreement with
      Pierpont Group, Inc. ("Group") to assist the trustees in exercising their
      overall supervisory responsibilities for the trust's affairs. The trustees
      of the trust represent all the existing shareholders of Group. The fund's
      allocated portion of Group's costs in performing its services amounted to
      $14,131 for the six months ended April 30, 1998.
 
   e) An aggregate annual fee of $75,000 is paid to each trustee for serving as
      a trustee of the trust, J.P. Morgan Funds, the master portfolios and J.P.
      Morgan Series Trust. The Trustees' Fees and Expenses

4. AGREEMENT
 
The trust, on behalf of the fund, together with other affiliated investment
companies (the "funds"), entered into a revolving line of credit agreement (the
"Agreement") on May 28, 1997, with unaffiliated lenders. Additionally, since all
of the investable assets of the fund are in the portfolio, the portfolio is
party to certain covenants of the Agreement. The maximum borrowing under the
Agreement is $150,000,000. The Agreement expires on May 27, 1998, however, the
fund as party to the Agreement has extended the Agreement and will continue its
participation therein for an additional 364 days until May 26, 1999. The maximum
borrowing under the new Agreement is $150,000,000. The purpose of the Agreement
is to provide another alternative for settling large fund shareholder
redemptions. Interest on any such borrowings outstanding will approximate market
rates. The funds pay a commitment fee at an annual rate of 0.065% on the unused
portion of the committed amount which is allocated to the funds in accordance
with procedures established by their respective trustees or directors. The fund
has not borrowed pursuant to the Agreement as of April 30, 1998.

THE U.S. FIXED INCOME PORTFOLIO
NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
APRIL 30, 1998
- --------------------------------------------------------------------------------
 
1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
The U.S. Fixed Income Portfolio (the "portfolio") is registered under the
Investment Company Act of 1940, as amended (the "Act"), as a no load, open-end
management investment company which was organized as a trust under the laws of
the State of New York on January 29, 1993. The portfolio commenced operations on
July 12, 1993 and received a contribution of certain assets and liabilities,
including securities, with a value of $91,653,371 on that date from J.P. Morgan
Bond Fund (formerly The JPM Pierpont Bond Fund) in exchange for a beneficial
interest in the portfolio. The portfolio's investment objective is to provide a
high total return consistent with moderate risk of capital and maintenance of
liquidity. The Declaration of Trust permits the trustees to issue an unlimited
number of beneficial interests in the portfolio.
 
Investments in emerging and international markets may involve certain
considerations and risks not typically associated with investments in the United
States. Future economic and political developments in emerging market and
foreign countries could adversely affect the liquidity or value, or both, of
such securities in which the portfolio is invested. The ability of the issuers
of debt, asset-backed and mortgage securities held by the portfolio to meet
their obligations may be affected by economic and political developments in a
specific industry or region. The value of asset-backed and mortgage securities
can be significantly affected by changes in interest rates or rapid principal
payments including pre-payments.
 
The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures. Actual amounts could differ from
those estimates. The following is a summary of the significant accounting
policies of the portfolio:
 
   a) The value of each security for which readily available market quotations
      exist is based on a decision as to the broadest and most representative
      market for such security. The value of such security will be based either
      on the last sale price on a national securities exchange or, in the
      absence of recorded sales, at the average of readily available closing bid
      and asked prices on such exchanges. Securities listed on a foreign
      exchange are valued at the last quoted sale price available before the
      time when net assets are valued. Unlisted securities are valued at the
      average of the quoted bid and asked prices in the over-the-counter market.
      Securities or other assets for which market quotations are not readily
      available are valued at fair value in accordance with procedures
      established by the portfolio's trustees. Such procedures include the use
      of independent pricing services, which use prices based upon yields or
      prices of securities of comparable quality, coupon, maturity and type;
      indications as to values from dealers; and general market conditions. All
      short-term portfolio securities with a remaining maturity of less than 60
      days are valued by the amortized cost method.
 
      Trading in securities on most foreign exchanges and over-the-counter
      markets is normally completed before the close of the domestic market and
      may also take place on days on which the domestic market is closed. If
      events materially affecting the value of foreign securities occur between
      the time when the exchange on which they are traded closes and the time
      when the portfolio's net assets are calculated, such securities will be
      valued at fair value in accordance with procedures established by and
      under the general supervision of the portfolio's trustees.

      The portfolio's custodian or designated subcustodians, as the case may be,
      under triparty repurchase agreements,takes possession of the collateral
      pledged for investments in repurchase agreements on behalf of the
      portfolio. It is the policy of the portfolio to value the underlying
      collateral daily on a mark-to-market basis to determine that the value,
      including accrued interest, is at least equal to the repurchase price plus
      accrued interest. In the event of default of the obligation to repurchase,
      the portfolio has the right to liquidate the collateral and apply the
      proceeds in satisfaction of the obligation. Under certain circumstances,
      in the event of default or bankruptcy by the other party to the agreement,
      realization and/or retention of the collateral or proceeds may be subject
      to legal proceedings.
 
   b) The books and records of the portfolio are maintained in U.S. dollars. The
      market value of investment securities, other assets and liabilities and
      foreign currency contracts are translated at the prevailing exchange rates
      at the end of the period. Purchases, sales, income and expenses are
      translated at the exchange rates prevailing on the respective dates of
      such transactions. Translation gains and losses resulting from changes in
      exchange rates during the reporting period and gains and losses realized
      upon settlement of foreign currency transactions are reported in the
      Statement of Operations. Although the net assets of the portfolio are
      presented at the exchange rates and market values prevailing at the end of
      the period, the portfolio does not isolate the portion of the results of
      operations arising as a result of changes in foreign exchange rates from
      the fluctuations arising from changes in the market prices of securities
      during the period.
 
   c) Securities transactions are recorded on a trade date basis. Dividend
      income is recorded on the ex-dividend date or as of the time that the
      relevant ex-dividend date and amount becomes known. Interest income, which
      includes the amortization of premiums and discounts, if any, is recorded
      on an accrual basis. For financial and tax reporting purposes, realized
      gains and losses are determined on the basis of specific lot
      identification.
 
   d) The portfolio may enter into forward and spot foreign currency contracts
      to protect securities and related receivables and payables against
      fluctuations in future foreign currency rates. A forward contract is an
      agreement to buy or sell currencies of different countries on a specified
      future date at a specified rate. Risks associated with such contracts
      include the movement in the value of the foreign currency relative to the
      U.S. dollar and the ability of the counterparty to perform.
 
                                                                              37

      The market value of the contract will fluctuate with changes in currency
      exchange rates. Contracts are valued daily at the current foreign exchange
      rates, and the change in the market value is recorded by the portfolio as
      unrealized appreciation or depreciation of forward foreign currency
      contract translations. At April 30, 1998, the portfolio had open forward
      currency contracts as follows:

   e) Futures -- A futures contract is an agreement to purchase/sell a specified
      quantity of an underlying instrument at a specified future date or to
      make/receive a cash payment based on the value of a securities index. The
      price at which the purchase and sale will take place is fixed when the
      portfolio enters into the contract. Upon entering into such a contract,
      the portfolio is required to pledge to the broker an amount of cash and/or
      liquid securities equal to the minimum "initial margin" requirements of
      the exchange. Pursuant to the contract, the portfolio agrees to receive
      from, or pay to, the broker an amount of cash equal to the daily
      fluctuation in the value of the contract. Such receipts or payments are
      known as "variation margin" and are recorded by the portfolio as
      unrealized gains or losses. When the contract is closed, the portfolio
      records a realized gain or loss equal to the difference between the value
      of the contract at the time it was opened and the value at the time when
      it was closed. The portfolio invests in futures contracts for the purpose
      of hedging its existing portfolio securities, or securities the portfolio
      intends to purchase, against fluctuations in value caused by changes in
      prevailing market interest rates or securities movements. The use of
      futures transactions involves the risk of imperfect

   f) The fund may enter into commitments to buy and sell investments to settle
      on future dates as part of its normal investment activities. These
      commitments are reported at market value in the financial statements.
      Credit risk exists on these commitments to the extent of any unrealized
      gains on the underlying securities purchased and any unrealized losses on
      the underlying securities sold. Market risk exists on these commitments to
      the same extent as if the security were owned on a settled basis and gains
      and losses are recorded and reported in the same manner. However, during
      the commitment period, these investments earn no interest or dividends.
 
   g) The portfolio intends to be treated as a partnership for federal income
      tax purposes. As such, each investor in the portfolio will be taxed on its
      share of the portfolio's ordinary income and capital gains. It is intended
      that the portfolio's assets will be managed in such a way that an investor
      in the portfolio will be able to satisfy the requirements of Subchapter M
      of the Internal Revenue Code. The portfolio earns foreign income which may
      be subject to foreign withholding taxes at various rates.
 
2. TRANSACTIONS WITH AFFILIATES
 
   a) The portfolio has an Investment advisory agreement with Morgan Guaranty
      Trust Company of New York ("Morgan"). Under the terms of the agreement,
      the portfolio pays Morgan at an annual rate of 0.30% of the portfolio's
      average daily net assets. For the six months ended April 30, 1998, this
      fee amounted to $1,657,846.
 
   b) The portfolio has retained Funds Distributor, Inc. ("FDI"), a registered
      broker-dealer, to serve as the co-administrator and exclusive placement
      agent. Under a Co-Administration Agreement between FDI and the portfolio,
      FDI provides administrative services necessary for the operations of the
      portfolio, furnishes office space and facilities required for conducting
      the business of the portfolio and pays the compensation of the officers
      affiliated with FDI. The portfolio has agreed to pay FDI fees equal to its
      allocable share of an annual complex-wide charge of $425,000 plus FDI's
      out-of-pocket expenses. The amount allocable to the portfolio is based on
      the ratio of the portfolio's net assets to the aggregate net assets of the
      portfolio and certain other investment companies subject to similar
      agreements with FDI. For the six months ended April 30, 1998, the fee for
      these services amounted to $11,478.
 
   c) The portfolio has an Administrative Services Agreement (the "Services
      Agreement") with Morgan under which Morgan is responsible for overseeing
      certain aspects of the administration and operation of the portfolio.
      Under the Services Agreement, the portfolio has agreed to pay Morgan a fee
      equal to its allocable share of an annual complex-wide charge. This charge
      is calculated based on the aggregate
 
                                                                              39

      average daily net assets of the portfolio and the other portfolios for
      which Morgan acts as investment advisor (the "master portfolios") and J.P.
      Morgan Series Trust (formerly JPM Series Trust) in accordance with the
      following annual schedule: 0.09% on 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 portfolio is
      determined by the proportionate share that its net assets bear to the net
      assets of the master portfolios, and certain other investors in the master
      portfolios for which Morgan provides similar services and J.P. Morgan
      Series Trust. For the six months ended April 30, 1998, the fee for these
      services amounted to $165,103.
 
   d) The portfolio has a Fund Services Agreement with Pierpont Group, Inc.
      ("Group") to assist the trustees in exercising their overall supervisory
      responsibilities for the portfolio's affairs. The trustees of the
