                                  1-888-MERRMAC

   
The Merrimac Series (the "Trust") is an open-end management investment company
consisting of the following four separate series of shares (each, a "Fund" and
collectively, the "Funds"):

                              Merrimac Cash Series
                            Merrimac Treasury Series
                          Merrimac Treasury Plus Series
                    Merrimac Short-Term Asset Reserve Series

Investment Objective. The investment objective of each Fund is to achieve a high
level of current income consistent with preserving principal and liquidity. The
Merrimac Cash Series, the Merrimac Treasury Plus Series and the Merrimac
Treasury Series are money market funds, while the Merrimac Short-Term Asset
Reserve Series is a short term fixed income fund.
    

Classes of Shares. Each of the Funds offers three classes of shares: Premium
Class, Institutional Class and Investment Class. The minimum initial investment
for Premium Class shares of each Fund is $10 million. The minimum initial
investment for Institutional Class and Investment Class shares of each Fund is
$10,000. See "Purchases and Redemptions" for more information about each class
of shares.

   
This Prospectus sets forth basic information that a prospective investor should
know before investing in any of the Funds and should be read and retained for
future reference. A Statement of Additional Information (the "SAI"), dated
January __, 1999, has been filed with the Securities and Exchange Commission
(the "SEC") and is incorporated by reference into this Prospectus. A copy of the
SAI may be obtained free of charge by calling the toll-free number above.

Investment in the Funds is neither insured nor guaranteed by the U.S.
Government, and is not a deposit or obligation of, or guaranteed or endorsed by,
Investors Bank & Trust Company. Further, investment in the Funds is not insured
by the Federal Deposit Insurance Corporation or any other government agency, and
involves investment risks, including possible loss of principal amount invested.
The Merrimac Cash Series, the Merrimac Treasury Plus Series and the Merrimac
Treasury Series attempt to maintain a stable net asset value of $1.00 per share;
however, there can be no assurance that either Fund will be able to do so. The
Merrimac Short-Term Asset Reserve Series is not a money market fund and will not
seek to maintain a stable net asset value.
    

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A

                                     Summary

The following is a brief summary of the proposed terms for the Funds. It is
qualified in its entirety by the detailed information appearing elsewhere in
this Prospectus.

Investment Objective: The Funds will seek to achieve a high level of current
income consistent with preserving principal and liquidity.

Minimum Initial Investment: $10 million for the Premium Class, $10,000 for the
Institutional Class and $10,000 for the Investment Class.

   
Net Asset Value: The Merrimac Cash Series (the "Cash Series"), the Merrimac
Treasury Plus Series (the "Treasury Plus Series") and the Merrimac Treasury
Series (the "Treasury Series") will seek to maintain a $1.00 per share net asset
value; however, there can be no assurance that any Fund will be able to do so.
The net asset value of the Merrimac Short-Term Asset Reserve Series (the "STAR
Series") will not remain constant but will fluctuate, as described below.

Master-Feeder Structure: Traditional mutual funds directly acquire and manage
their own portfolio securities. As part of a master-feeder structure, the Funds
seek to achieve their investment objective by investing all of their investable
assets in their corresponding Portfolio. The Cash Series, the Treasury Plus
Series and the Treasury Series each seek to achieve their investment objective
by investing all of their investable assets in the Merrimac Cash Portfolio (the
"Cash Portfolio"), the Merrimac Treasury Plus Portfolio (the "Treasury Plus
Portfolio") and the Merrimac Treasury Portfolio (the "Treasury Portfolio"),
respectively. The STAR Series seeks to achieve its objective by investing all of
its investable assets in the Standish Short-Term Asset Reserve Portfolio (the
"STAR Portfolio"). The Cash Portfolio, the Treasury Plus Portfolio, the Treasury
Portfolio and the STAR Portfolio are hereinafter referred to singly as a
"Portfolio," and collectively as the "Portfolios." Each Fund's investment
experience will correspond directly with the investment experience of its
corresponding Portfolio.

Investment Portfolios and Policies: The Cash Portfolio, the Treasury Plus
Portfolio and the Treasury Portfolio each invest in high quality money market
instruments which represent minimal credit risk. Currency exposure is restricted
to U.S. dollars. When it is anticipated that short-term interest rates will
decrease, the average maturity of the Cash Portfolio, the Treasury Plus
Portfolio and the Treasury Portfolio may be increased to lock-in prevailing
rates prior to an anticipated decrease in rates. Conversely, when it is
anticipated that short-term interest rates will increase, the average maturity
of the Cash Portfolio, the Treasury Plus Portfolio and the Treasury Portfolio
may be reduced. The Portfolios will maintain a dollar-weighted average maturity
of 90 days or less and will not invest in securities with remaining maturities
of more than 397 days.
    

The STAR Portfolio invests in a broad range of investment grade money market
instruments and short-term fixed income securities. The STAR Portfolio may also
invest in tax-exempt securities and prime commercial paper of U.S. and foreign
companies, and may enter into reverse repurchase agreements. The STAR Portfolio
limits its investments in preferred stock and tax exempt securities to 10% of
its total assets.

   
Investment Advisers and Sub-Advisers: Investors Bank & Trust Company ("Investors
Bank") acts as Investment Adviser to the Cash Portfolio, the Treasury Plus
Portfolio and the Treasury Portfolio. Investors Bank's business address is 200
Clarendon Street, Boston, Massachusetts 02116. As Investment Adviser, Investors
Bank continuously reviews and supervises the investment program for the Cash


                                       3

business address is 440 Lincoln Street, Worcester, Massachusetts 01653. M&I's

the purchase and sale of the STAR Portfolio's investments.

   
Purchase Orders and Related Dividend Timing: Purchase orders received by 5:00
p.m. Eastern Time (ET) for the Cash Series and the Treasury Plus Series, 2:00
p.m. (ET) for the Treasury Series, and by the close of trading on the New York

Time of Net Asset Value Calculation: As of 5:00 p.m. (ET) for the Cash Series

    (1)The Management Fee of the Cash Series, the Treasury Plus Series and the
       Treasury Series includes fees payable to the relevant Investment
       Sub-Adviser.

    (2)The amounts set forth for "Other Expenses" include fees for legal and
       accounting services, printing and regulatory filings and are based on
       estimates for the current fiscal year. Investors Bank has voluntarily
       agreed to limit Total Fund Operating Expenses (excluding litigation,
       indemnification, taxes and other extraordinary expenses) of the STAR
       Series to 0.36% of average daily net assets. In the absence of this
       agreement, Other Expenses and Total Fund Operating Expenses are estimated
       to be equal, on an annual basis, to 0.20% and 0.45%, respectively, of the
       Star Series' average daily net assets. This agreement is voluntary and
       temporary and may be revised by Investors Bank at any time although it
       has no current intention to do so.

       Example: A shareholder would pay the following expenses on a $1,000
       investment, assuming (1) 5% annual return and (2) with or without
       redemption at the end of each period:

                          The Funds and the Portfolios

Each Fund is a diversified series of the Trust, an open-end, management
investment company registered under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Trust was organized under the laws of the state of
Delaware on March 31, 1998 and is currently authorized to issue shares in four
series: the Cash Series, the Treasury Plus Series, the Treasury Series and the
STAR Series. Shareholders of each Fund are entitled to one vote for each share
and to the appropriate fractional vote for each fractional share of their
respective Fund. There is no cumulative voting. Shares have no preemptive or
conversion rights. Shares are fully paid and nonassessable by the Trust. The
Trust does not intend to hold meetings of shareholders, except as required under
the 1940 Act.

The Cash Portfolio, the Treasury Plus Portfolio and the Treasury Portfolio are
each diversified series of the Merrimac Master Portfolio (the "Portfolio
Trust"), an open-end, management investment company registered under the 1940
Act. The Portfolio Trust is a common law trust organized under the laws of the
state of New York on October 30, 1996 and is currently authorized to issue
interests in three series: the Cash Portfolio, the Treasury Plus Portfolio and
the Treasury Portfolio.
    

The STAR Portfolio is a diversified series of Standish, Ayer & Wood Master
Portfolio (the "Standish Portfolio Trust"), an open-end, management investment
company registered under the 1940 Act. The Standish Portfolio Trust is a common
law trust organized under New York law on January 18, 1996 and is authorized to
issue interests in seven series, including the STAR Portfolio. Interests in the
Portfolios have no preemptive or conversion rights, and are fully paid and
non-assessable by each Portfolio. Neither the Portfolio Trust nor the Standish
Portfolio Trust will hold meetings of holders of such interests, except as
required under the 1940 Act.

The Board of Trustees of each of the Trust, the Portfolio Trust and the Standish
Portfolio Trust is generally responsible for management of the business and
affairs of the Trust, the Portfolio Trust and the Standish Portfolio Trust,
respectively. Trustees formulate general policies, approve contracts and
authorize officers to carry out the decisions of such Board. See the SAI for
more information concerning the management of each of the Trust, the Portfolio
Trust and the Standish Portfolio Trust.

                       Investment Objectives and Policies

   
The investment objective of each Fund is to obtain a high level of current
income consistent with the preservation of principal and liquidity. There is no
assurance that the Funds will achieve their investment objectives. Each Fund's
investment objective and investment policies (other than the policies identified
under "Investment Restrictions" below) are not fundamental and may be changed at
any time by the Board of Trustees of the Trust (the "Board of Trustees" or the
"Trustees").

Because each Fund invests all of its investable assets in its corresponding
Portfolio, the investment objective and characteristics of each Fund correspond
directly to those of its Portfolio. See "Additional Information Concerning
Investment Structure" for more information. The Cash Portfolio, the Treasury
Plus Portfolio and the Treasury Portfolio seek to achieve the same objectives as
their corresponding Funds by investing in high quality U.S. dollar denominated
money market instruments. The STAR Portfolio seeks to achieve the same objective
as the STAR Series by investing in a broad range of investment grade money
market instruments and short-term fixed income securities.

Money Market Funds

The Cash Portfolio, the Treasury Plus Portfolio and the Treasury Portfolio will
each operate as a "money market mutual fund" and all investments will qualify as
"eligible securities" within the meaning of Rule 2a-7 under the 1940 Act.
Consistent with Rule 2a-7, neither the Cash Portfolio, the Treasury Plus
Portfolio nor the Treasury Portfolio will purchase securities of any issuer
(except securities issued or guaranteed by the United States Government, and
with respect to the Cash Portfolio and the Treasury Plus Portfolio, securities
issued or guaranteed by agencies or instrumentalities of the United States
Government and repurchase agreements involving such securities) if as a result
more than 5% of the total assets of either the Cash Portfolio, the Treasury Plus
Portfolio or the Treasury Portfolio would be invested in the securities of such
issuer or the Cash Portfolio, the Treasury Plus Portfolio or the Treasury
Portfolio would own more than 10% of the outstanding voting securities of such
issuer.

Although the policies of the Cash Series, the Treasury Plus Series, the Treasury
Series, the Cash Portfolio, the Treasury Plus Portfolio and the Treasury
Portfolio are designed to maintain a stable net asset value of $1.00 per share,
all money market instruments can change in value when interest rates or an
issuer's creditworthiness changes, or if an issuer or guarantor of a security
fails to pay interest or principal when due. If these changes in value were
substantial, the Cash Series, the Treasury Plus Series or the Treasury Series'
net asset value could deviate from $1.00.
    

Cash Portfolio. The Cash Portfolio may invest in U.S. Treasury bills, notes and
bonds, and other instruments issued or guaranteed by the U.S. Government or its
agencies or instrumentalities ("U.S. Government Securities"); securities of U.S.
and foreign banks or thrift organizations (such as bankers' acceptances, time
deposits and certificates of deposit); corporate debt obligations, including
commercial paper, notes and bonds and other money market instruments;
asset-backed securities; and variable rate obligations (defined as a security
whose coupon rate resets at least every six months). The Cash Portfolio also may
invest in repurchase agreements that are collateralized by the securities listed
above with no restrictions on the maturity of obligations collateralizing such
repurchase agreements and may engage in securities lending.

   
Treasury Plus Portfolio. The Treasury Plus Portfolio will invest, under normal
circumstances, at least 65% of its assets in direct obligations of the U.S.
Treasury and may invest the remaining 35% of its assets in U.S. Government
Securities and in repurchase agreements that are collateralized by U.S.
Government Securities with no restrictions on the maturity of obligations
collateralizing such repurchase agreements and may engage in securities lending.

Treasury Portfolio. The Treasury Portfolio will only invest in direct
obligations of the U.S. Treasury. Under Federal law, the income derived from
obligations issued by the U.S. Treasury is exempt from state income taxes. All
states that tax personal income permit mutual funds to pass through this tax
exemption to shareholders, assuming appropriate state imposed threshold limits
have been met. To maximize tax-effective yield for shareholders, under normal
circumstances, the Treasury Portfolio will only invest in obligations that
qualify for the exemption from state taxation. The Treasury Portfolio also may
engage in securities lending.


                                       10
<PAGE>


Although the Cash Portfolio, the Treasury Plus Portfolio, the Treasury Portfolio
and the Star Portfolio invest in U.S. Government Securities, neither an
investment in any of the Funds nor a Fund's investment in its corresponding
Portfolio is insured or guaranteed by the U.S. Government.
    

STAR Portfolio. The STAR Portfolio invests in a broad range of investment grade
money market instruments and short-term fixed-income securities. The STAR
Portfolio may invest in all types of fixed-income securities, including bonds,
notes (including structured or hybrid notes), mortgage-backed securities,
asset-backed securities, shares of real estate investment trusts ("REITs"),
convertible securities, Eurodollar and Yankee Dollar instruments, preferred
stocks (including convertible preferred stock), and money market instruments
(such as negotiable certificates of deposit, non-negotiable fixed time deposits,
bankers' acceptances and prime commercial paper). These fixed income securities
may be issued by the U.S. Government, its agencies, authorities,
instrumentalities or sponsored enterprises, U.S. and foreign banks, U.S. and
(solely with respect to prime commercial paper) foreign companies. The STAR
Portfolio limits its investments in each of tax-exempt securities and preferred
stocks to 10% of its total assets. The STAR Portfolio may purchase securities
that pay interest on a fixed, variable, floating, inverse floating, contingent,
in-kind or deferred basis. The STAR Portfolio may enter into repurchase
agreements, reverse repurchase agreements and forward dollar roll transactions,
may purchase zero coupon and deferred payment securities, and may buy securities
on a when-issued or delayed delivery basis. The STAR Portfolio may also purchase
shares of other investment companies and real estate investment trusts. The net
asset value of the STAR Series will not remain constant but will fluctuate with
the value of the assets of the STAR Portfolio.

In selecting investments for the STAR Portfolio, Standish's primary investment
management and research focus is at the security and industry/sector level.
Standish manages the STAR Portfolio by selecting undervalued investments, rather
than by varying the average maturity of the securities to reflect interest rate
forecasts. Fundamental credit and sector valuation techniques are used to
evaluate what are considered to be less efficient markets and sectors of the
fixed income marketplace in an attempt to select securities with the potential
for the highest return.

Maturity

   
Cash Portfolio, Treasury Plus Portfolio and Treasury Portfolio. The Cash
Portfolio, the Treasury Plus Portfolio and the Treasury Portfolio will maintain
a dollar-weighted average maturity of 90 days or less and will not invest in
securities with remaining maturities of more than 397 days (as determined in
accordance with Rule 2a-7 under the 1940 Act.) The Cash Portfolio, the Treasury
Plus Portfolio and the Treasury Portfolio may invest in variable or floating
rate securities which bear interest at rates subject to periodic adjustment or
which provide for periodic recovery of principal on demand.
    

STAR Portfolio. Securities held by the STAR Portfolio will generally have an
effective or remaining maturity of 3.25 years or less from the date of
settlement, except that up to 10% of the STAR Portfolio's total assets may be
represented by securities with effective maturities or redemption dates, put
dates or coupon dates of between 3.25 and five years. The maturity limitation
does not apply to U.S. Treasury notes or bonds with maturities of longer than
3.25 years, which may be purchased by the STAR Portfolio in conjunction with the
sale of note or bond futures contracts or with certain equivalent options
positions which are designed to hedge the notes or bonds in such a way as to
create a synthetic short-term instrument. The STAR Portfolio's average
dollar-weighted effective portfolio maturity will not exceed 18 months.


                                       11


<PAGE>


Quality

   
Cash Portfolio. The Cash Portfolio intends to incur limited credit risk by only
purchasing securities, in addition to U.S. Government Securities, that are rated
in the highest or second highest rating categories (i.e., Prime-1 or Prime-2 by
Moody's Investors Service, Inc. ("Moody's"), A-1 or A-2 by Standard & Poor's
Ratings Group ("Standard & Poor's"), Fitch-1 or Fitch 2 by Fitch's Investors
Service ("Fitch"), Duff-1 or Duff-2 by Duff and Phelps ("Duff"), or A1 or A2 by
IBCA Limited ("IBCA") for short-term obligations by at least two nationally
recognized statistical rating organizations ("NRSROs"). As a matter of operating
policy, however, the Cash Portfolio will only invest in securities, exclusive of
U.S. Government Securities, that are rated in the highest rating category for
short-term obligations by at least two NRSROs. Investments in high quality,
short-term instruments may, in many circumstances, result in a lower yield than
would be available from investments in instruments with a lower quality or a
longer term. See "Description of Permitted Investments and Related Risks" in
this Prospectus for more information regarding each Portfolio's investment
policies. See also Appendix A to the SAI for a description of NRSRO ratings.
    

STAR Portfolio. The STAR Portfolio invests primarily in high grade securities,
which are those securities that are rated within the top three rating categories
(i.e., Aaa, Aa, A or P-1 by Moody's or AAA, AA, A, A-1 or Duff-1 by Standard &
Poor's, Duff, Fitch or IBCA or, if unrated, determined by Standish to be of
comparable credit quality. The STAR Portfolio may also invest up to 15% of its
total assets in medium grade obligations rated Baa or P-2 by Moody's or BBB, A-2
or Duff-2 by Standard & Poor's, Duff, Fitch or IBCA, or, if unrated, determined
by Standish to be of comparable credit quality. The average dollar-weighted
credit quality of the STAR Portfolio's portfolio securities is expected to be at
least Aa according to Moody's or AA according to Standard & Poor's, Duff, Fitch
or IBCA. If a security is rated differently by two or more rating agencies,
Standish uses the highest rating to compute the STAR Portfolio's credit quality
and also to determine a security's rating category. If the rating of a security
is downgraded below the minimum rating required for the STAR Portfolio, Standish
will determine whether to retain that security in the portfolio.

Securities rated in the lowest category of investment grade (Baa or P-2 by
Moody's or BBB, A-2 or Duff-2 by Standard & Poor's, Duff, Fitch or IBCA) are
generally considered medium grade obligations and have some speculative
characteristics. Adverse changes in economic conditions or other circumstances
are more likely to weaken the medium grade issuer's capability to pay interest
and repay principal than is the case for high grade securities.

             Description of Permitted Investments and Related Risks

General

Investment in the Funds involve certain risks. Each Portfolio invests in money
market instruments and the STAR Portfolio invests in high and medium grade fixed
income securities. Such securities can change in value when interest rates or an
issuer's creditworthiness changes, or if an issuer or guarantor of a security
fails to pay interest or principal when due. The risks involved with such
securities include interest rate risk, default risk and call and extension risk.

Interest Rate Risk. When interest rates decline, the market value of money
market instruments and fixed income securities tends to increase. Conversely,
when interest rates increase, market values tend to decline. The volatility of a
security's market value will differ depending upon the security's duration, the
issuer and the type of instrument.


                                       12


<PAGE>


Default/Credit Risk. Investments in money market instruments and fixed income
securities are subject to the risk that the issuer of the security could default
on its obligations causing a Portfolio to sustain losses on such investments. A
default could impact both interest and principal payments.

Call and Extension Risk. Fixed income securities may be subject to both call
risk and extension risk. Call risk exists when the issuer may exercise a right
to pay principal on an obligation earlier than scheduled which would cause cash
flows to be returned earlier than expected. This typically results when interest
rates have declined and the STAR Portfolio could suffer from having to reinvest
in lower yielding securities. Extension risk exists when the issuer may exercise
a right to pay principal on an obligation later than scheduled which would cause
cash flows to be returned later than expected. This typically results when
interest rates have increased and the STAR Portfolio could suffer from the
inability to invest in higher yielding securities.

Year 2000. Like other mutual funds, governmental and business organizations and
individuals around the world, the Funds could be adversely affected if the
computer systems used by the Investors Bank, AAM, M&I, Standish and other
service providers do not properly process and calculate date-related information
from and after January 1, 2000. This is commonly known as the "Year 2000
Problem." Each of the above entities is taking steps that it believes are
reasonably designed to address the Year 2000 Problem with respect to computer
systems that it uses and to obtain reasonable assurances that comparable steps
are being taken by the Funds' other major service providers. At this time,
however, there can be no assurance that these steps will be sufficient to avoid
any adverse impact to the Funds.

Permitted Investments and Related Risks

The following paragraphs include descriptions of the specific risks that are
associated with the Portfolios' purchase of a particular type of security or the
utilization of a specific investment technique.

   
U.S. Government Securities. Each Portfolio, other than the Treasury Portfolio,
may invest in securities that are issued or guaranteed by an agency or
instrumentality of the U.S. Government established under the authority of an act
of Congress. Not all U.S. Government Securities are backed by the full faith and
credit of the United States. For example, securities issued by the Federal Farm
Credit Bank or by the Federal National Mortgage Association are supported by the
agency's right to borrow money from the U.S. Treasury under certain
circumstances. Securities issued by the Federal Home Loan Bank are supported
only by the credit of the agency. There is no guarantee that the U.S. Government
will support these types of securities, and therefore they involve more risk
than "full faith and credit" government securities.

Bankers' Acceptances. The Cash Portfolio and the STAR Portfolio may invest in
bankers' acceptances which are bills of exchange or time drafts drawn on and
accepted by a commercial bank. They are used by corporations to finance the
shipment and storage of goods and to furnish dollar exchange. Maturities are
generally six months or less.

Time Deposits. The Cash Portfolio and the STAR Portfolio may invest in time
deposits ("TDs"), which are non-negotiable receipts issued by a bank in exchange
for the deposit of funds. Like a certificate of deposit, a TD earns a specified
rate of interest over a definite period of time; however it cannot be traded in
the secondary market.



                                       13
<PAGE>


Certificates of Deposit. The Cash Portfolio and the STAR Portfolio also may
invest in certificates of deposit ("CDs"), which are negotiable interest bearing
instruments with a specific maturity. CDs are issued by banks and thrift
institutions in exchange for the deposit of funds and normally can be traded in
the secondary market prior to maturity.

Commercial Paper. The Cash Portfolio and the STAR Portfolio may invest in
commercial paper, which is the term used to designate unsecured short-term
promissory notes issued by corporations and other entities. The Cash Portfolio
and the Treasury Plus Portfolio may invest in commercial paper with maturities
which vary from a few days to nine months. The Cash Portfolio and the Treasury
Plus Portfolio may also purchase U.S. dollar-denominated commercial paper of a
foreign issuer rated in the highest or second highest rating categories by at
least two NRSROs. The STAR Portfolio may purchase U.S. dollar denominated
commercial paper of U.S. and foreign issuers rated A-2 by Moody's or P-2 or
Duff-2 by Standard & Poor's, Duff, Fitch or IBCA.

Corporate Debt Obligations. Subject to their respective credit quality and
maturity limitations, the Cash Portfolio and the STAR Portfolio may invest in
corporate bonds, including obligations of industrial, utility, banking and other
financial issuers. Corporate bonds are subject to the risk of an issuer's
inability to meet principal and interest payments and may also be subject to
price volatility due to such factors as market interest rates, market perception
of the creditworthiness of the issuer and general market liquidity.

Asset-Backed Securities. The Cash Portfolio and the STAR Portfolio may invest in
asset-backed securities, which consist of securities secured by company
receivables, home equity loans, truck and auto loans, leases, credit card
receivables and other securities backed by other types of receivables or other
assets. Credit support for asset-backed securities may be based on the
underlying assets and/or provided through credit enhancements such as letters of
credit, insurance bonds, limited issuer guarantees, senior-subordinated
structures and over-collateralization. Asset-backed securities are normally
traded over-the-counter and typically have a short-intermediate maturity
structure depending on the paydown characteristics of the underlying financial
assets which are passed through to the security holder. Asset-backed securities
may be subject to prepayment risk, particularly in a period of declining
interest rates. Prepayments, which occur when unscheduled payments are made on
the underlying debt instruments, may shorten the effective maturities of these
securities and may lower their total returns. Asset-backed securities generally
do not have the benefit of a security interest in collateral that is comparable
to mortgage assets and there is the possibility that recoveries on repossessed
collateral may not be available to support payments on these securities. There
is no limit on the extent to which the Cash and STAR Portfolios may invest in
asset-backed securities; however, the Cash Portfolio will only invest in
asset-backed securities that carry a rating in the highest category from at
least two NRSROs.
    

Mortgage-Backed Securities. The STAR Portfolio may invest in privately issued
mortgage-backed securities and mortgage-backed securities issued or guaranteed
by the U.S. Government or any of its agencies, instrumentalities or sponsored
enterprises, including, but not limited to, the Government National Mortgage
Association ("GNMA"), the Federal National Mortgage Association ("FNMA") and the
Federal Home Loan Mortgage Corporation ("FHLMC"). Mortgage-backed securities
represent direct or indirect participations in, or are collateralized by and
payable from, mortgage loans secured by real property. Mortgagors can generally
prepay interest or principal on their mortgages whenever they choose. Therefore,
mortgage-backed securities are often subject to more rapid repayment than their
stated maturity date would indicate as a result of principal prepayments on the
underlying loans. This can 


                                       14
<PAGE>


result in significantly greater price and yield volatility than is the case with
traditional fixed income securities. During periods of declining interest rates,
prepayments can be expected to accelerate, and thus impair the STAR Portfolio's
ability to reinvest the returns of principal at comparable yields. Conversely,
in a rising interest rate environment, a declining prepayment rate will extend
the average life of many mortgage-backed securities, increase the STAR
Portfolio's exposure to rising interest rates and prevent the STAR Portfolio
from taking advantage of such higher yields.

GNMA securities are backed by the full faith and credit of the U.S. Government,
which means that the U.S. Government guarantees that the interest and principal
will be paid when due. FNMA securities and FHLMC securities are not backed by
the full faith and credit of the U.S. Government; however, these enterprises
have the ability to obtain financing from the U.S. Treasury. See the SAI for
additional descriptions of GNMA, FNMA and FHLMC certificates.

Multiple class securities include collateralized mortgage obligations ("CMOs")
and Real Estate Mortgage Investment Conduit ("REMIC") pass-through or
participation certificates. CMOs provide an investor with a specified interest
in the cash flow from a pool of underlying mortgages or other mortgage-backed
securities. CMOs are issued in multiple classes, each with a specified fixed or
floating interest rate and a final scheduled distribution date. In most cases,
payments of principal are applied to the CMO classes in the order of their
respective stated maturities, so that no principal payments will be made on a
CMO class until all other classes having an earlier stated maturity date are
paid in full. A REMIC is a CMO that qualifies for special tax treatment under
the Internal Revenue Code of 1986, as amended (the "Code"), and invests in
certain mortgages principally secured by interests in real property and other
permitted investments. The STAR Portfolio does not intend to purchase residual
interests in REMICs.

Convertible Securities. The STAR Portfolio may invest in convertible securities
consisting of bonds, notes, debentures and preferred stocks. The STAR
Portfolio's investments in preferred stock are limited to no more than 10% of
its total assets. Convertible debt securities and preferred stock acquired by
the STAR Portfolio entitle the STAR Portfolio to exchange such instruments for
common stock of the issuer at a predetermined rate. Convertible securities are
subject both to the credit and interest rate risks associated with debt
obligations and to the stock market risk associated with equity securities.

Inverse Floating Rate Securities. The STAR Portfolio may invest in inverse
floating rate securities. the interest on which resets in the opposite direction
from the market rate of interest to which the inverse floater is indexed. An
inverse floater may be considered to be leveraged to the extent that its
interest rate varies by a magnitude that exceeds the magnitude of the change in
the index rate of interest. The higher the degree of leverage of an inverse
floater, the greater the volatility of its market value.

Zero Coupon and Deferred Payment Securities. The STAR Portfolio may invest in
zero coupon and deferred payment securities. Zero coupon securities are
securities sold at a discount to par value and on which interest payments are
not made during the life of the security. Upon maturity, the holder is entitled
to receive the par value of the security. The STAR Portfolio is required to
accrue income with respect to these securities prior to the receipt of cash
payments. Because the STAR Series will distribute its share of this accrued
income to shareholders, to the extent that the STAR Series' shareholders and
shareholders of other mutual funds that invest in the STAR Portfolio elect to
receive dividends in cash rather than reinvesting such dividends in additional
shares, the STAR Portfolio will have fewer assets with which to purchase income
producing securities. Deferred payment securities are securities that remain
zero coupon securities until a predetermined date, at which time the stated
coupon rate becomes effective and interest becomes payable at regular intervals.
Zero coupon and deferred payment securities may be 



                                       15
<PAGE>


subject to greater fluctuation in value and may have less liquidity in the event
of adverse market conditions than comparably rated securities paying cash
interest at regular interest payment periods. The Treasury Portfolio and the
Treasury Plus Portfolio may invest in zero coupon treasury securities.

Structured or Hybrid Notes. The STAR Portfolio may invest in structured or
hybrid notes. The distinguishing feature of a structured or hybrid note is that
the amount of interest and/or principal payable on the note is based on the
performance of a benchmark asset or market other than fixed income securities or
interest rates. Examples of these benchmarks include stock prices, currency
exchange rates and physical commodity prices. Investing in a structured note
allows the STAR Portfolio to gain exposure to the benchmark security while
fixing the maximum loss that it may experience in the event that the security
does not perform as expected. Depending on the terms of the note, the Portfolio
may forego all or part of the interest and principal that would be payable on a
comparable conventional note; the STAR Portfolio's loss cannot exceed this
foregone interest and/or principal. An investment in structured or hybrid notes
involves risks similar to those associated with a direct investment in the
benchmark security.

   
Eurodollar and Yankee Dollar Investments. The Cash Portfolio and the STAR
Portfolio may invest in Eurodollar and Yankee Dollar instruments. Eurodollar
instruments are bonds of foreign corporate and government issuers that pay
interest and principal in U.S. dollars held in banks outside the United States,
primarily in Europe. Yankee Dollar instruments are U.S. dollar denominated bonds
typically issued in the U.S. by foreign governments and their agencies and
foreign banks and corporations. The Portfolios may invest in Eurodollar
Certificates of Deposit ("ECDs"), Eurodollar Time Deposits ("ETDs") and Yankee
Certificates of Deposit ("Yankee CDs"). ECDs are U.S. dollar-denominated
certificates of deposit issued by foreign branches of domestic banks; ETDs are
U.S. dollar-denominated deposits in a foreign branch of a U.S. bank or in a
foreign bank; and Yankee CDs are U.S. dollar-denominated certificates of deposit
issued by a U.S. branch of a foreign bank and held in the U.S. These investments
involve risks that are different from investments in securities issued by U.S.
issuers, including potential unfavorable political and economic developments,
foreign withholding or other taxes, seizure of foreign deposits, currency
controls, interest limitations or other governmental restrictions which might
affect payment of principal or interest. In addition, issuers of Eurodollar
instruments are not subject to the same regulations as are domestic banks.
    

Tax-Exempt Securities. The STAR Portfolio is managed without regard to potential
tax consequences. If Standish believes that tax-exempt securities will provide
competitive returns, the STAR Portfolio may invest up to 10% of its total assets
in tax-exempt securities. The STAR Series' distributions of its share of any
interest earned by the STAR Portfolio from these investments will be taxable.

Other Investment Companies. Each Portfolio may invest up to 10% of its total
assets in shares of investment companies and up to 5% of its total assets in any
one investment company as long as the investment does not represent more than 3%
of the total voting stock of the acquired investment company. Investments in the
securities of other investment companies may involve duplication of advisory
fees and other expenses.

Real Estate Investment Trusts. The STAR Portfolio may invest in Real Estate
Investment Trusts ("REITs") which are pooled investment vehicles that invest in
real estate or real estate loans or interests. Investing in REITs involves risks
similar to those associated with investing in equity securities of small
capitalization companies. REITs are dependent upon management skills, are not
diversified, and are subject to risks of project financing, default by
borrowers, self-liquidation, and the possibility of failing to qualify for the
exemption from taxation under Subchapter M of the Code.



                                       16
<PAGE>


   
When-Issued and Delayed Delivery Transactions. Each Portfolio may invest in
when-issued and delayed delivery securities, which are securities purchased for
delivery beyond the normal settlement date at a stated price and yield, thereby
involving the risk that the yield obtained will be less then that available in
the market at delivery. The purchase of securities on a when-issued or delayed
delivery basis has the effect of leveraging. When such a security is purchased,
the Custodian will set aside cash or liquid securities to satisfy the purchase
commitment unless the relevant Portfolio has entered into an offsetting
agreement to sell the securities. These segregated securities will be valued at
market, and additional cash or securities will be segregated if necessary so
that the market value of the account will continue to satisfy the purchase
commitment. Such Portfolios generally will not pay for such securities or earn
interest on them until received. Commitments to purchase when-issued securities
will not, under normal market conditions, exceed 25% of the Treasury, Treasury
Plus or Cash Portfolios' total assets or 10% of the STAR Portfolio's total
assets, and a commitment will not exceed 90 days. Such Portfolios will only
purchase when-issued and delayed delivery securities for the purpose of
acquiring portfolio securities and not for speculative purposes. However, such
Portfolios may sell these securities or dispose of the commitment before the
settlement date if it is deemed advisable as a matter of investment strategy.
The market value of when-issued or delayed delivery securities when they are
delivered may be less than the amount such Portfolios paid for them.

Variable and Floating Rate Instruments. Certain of the obligations purchased by
each Portfolio may carry variable or floating rates of interest and may include
variable amount master demand notes. A floating rate security provides for the
automatic adjustment of its interest rate whenever a specified interest rate
changes. A variable rate security provides for the automatic establishment of a
new interest rate on set dates. Variable and floating rate instruments may
include variable amount master demand notes that permit the indebtedness
thereunder to vary in addition to providing for periodic adjustments in the
interest rate. There may be no active secondary market with respect to a
particular variable or floating rate instrument. Nevertheless, the periodic
readjustments of their interest rates tend to assure that their value to such
Portfolios will approximate their par value. Further, some of the demand
instruments purchased by such Portfolios derive their liquidity from the ability
of the holder to demand repayment from the issuer or from a third party
providing credit support. The creditworthiness of issuers of variable and
floating rate instruments and their ability to repay principal and interest will
be continuously monitored by such Portfolio's investment adviser or sub-adviser.

Repurchase Agreements. Each Portfolio, other than the Treasury Portfolio, may
enter into repurchase agreements, which are agreements by which a person obtains
a security and simultaneously commits to return the security to the seller at an
agreed upon price (including principal and interest) on an agreed upon date
within a number of days from the date of purchase. In substance, a repurchase
agreement is a loan by the applicable Portfolio collateralized with securities.
Such lending Portfolio's Custodian or its agent will hold the security as
collateral for the repurchase agreement. All repurchase transactions must be
collateralized initially at a value at least equal to 102% of the repurchase
price and counterparties are required to deliver additional collateral in the
event the market value of the collateral falls below 100%. Such Portfolios bear
the risk of loss in the event the other party defaults on its obligations and a
Portfolio is delayed in or prevented from disposing of the collateral securities
or if a Portfolio realizes a loss on the sale of the collateral securities. Such
Portfolios will enter into repurchase agreements with financial institutions
deemed to present minimal risk of bankruptcy during the term of the agreement
based on guidelines established and periodically reviewed by the Trustees of the
Portfolio Trust. The Cash Portfolio and the Treasury Plus Portfolio will not
invest more than 10% of their net assets in repurchase agreements maturing in
more than seven days. The STAR Portfolio may invest up to 25% of its net assets
in repurchase agreements. The repurchase transactions entered into by the
Treasury Plus Portfolio must be collateralized by treasury securities or U.S.
Government Securities.



                                       17
<PAGE>


Reverse Repurchase Agreements. Each Portfolio may borrow funds for temporary
purposes by entering into reverse repurchase agreements. Pursuant to such
agreements, such Portfolios would sell the securities to financial institutions
such as banks and broker-dealers and agree to repurchase them at a mutually
agreed-upon date and price. Such Portfolios will enter into reverse repurchase
agreements to avoid otherwise selling securities during unfavorable market
conditions and to provide cash to satisfy redemption requests. At the time a
Portfolio enters into a reverse repurchase agreement, it would place in a
segregated custodial account, assets such as cash or liquid securities,
consistent with a Portfolio's investment restrictions and having a value equal
to the repurchase price (including accrued interest), and would subsequently
monitor the account to ensure that such equivalent value was maintained. Reverse
repurchase agreements involve the risk that the counterparty may default at a
time when the market value of securities sold by a Portfolio have increased in
value. Reverse repurchase agreements are considered by the SEC to be borrowings
by a Portfolio under the 1940 Act.
    

Forward Roll Transactions. To seek to enhance current income, the STAR Portfolio
may invest up to 10% of its net assets in forward roll transactions involving
mortgage-backed securities. In a forward roll transaction, the STAR Portfolio
sells a mortgage-backed security to a financial institution, such as a bank or
broker-dealer, and simultaneously agrees to repurchase a similar security from
the institution at a later date at an agreed-upon price. The mortgage-backed
securities that are repurchased will bear the same interest rate as those sold,
but generally will be collateralized by different pools of mortgages with
different prepayment histories than those sold. During the period between the
sale and repurchase, the Portfolio will not be entitled to receive interest and
principal payments on the securities sold. Proceeds of the sale will be invested
in short-term instruments, such as repurchase agreements or other short-term
securities, and the income from these investments, together with any additional
fee income received on the sale and the amount gained by repurchasing the
securities in the future at a lower price, will generate income and gain for the
Portfolio which is intended to exceed the yield on the securities sold. Forward
roll transactions involve the risk that the market value of the securities sold
by the Portfolio may decline below the repurchase price of those securities. At
the time that a Portfolio enters into a forward roll transaction, it will place
cash or liquid assets in a segregated account that is marked to market daily
having a value equal to the repurchase price (including accrued interest).

Leverage. The use of forward roll transactions and reverse repurchase agreements
involves leverage. Leverage allows any investment gains made with the additional
monies received (in excess of the costs of the forward roll transaction or
reverse repurchase agreement) to increase the net asset value of a Portfolio
faster than would otherwise be the case. On the other hand, if the additional
monies received are invested in ways that do not fully recover the costs of such
transactions to a Portfolio, the net asset value of the Portfolio would fall
faster than would otherwise be the case.

   
Restricted and Illiquid Securities. Each Portfolio may invest up to 10% of its
net assets (15% of net assets with respect to the STAR Portfolio) in illiquid
securities. Illiquid securities are those that are not readily marketable,
repurchase agreements maturing in more than seven days, time deposits with a
notice or demand period of more than seven days and certain restricted
securities. Based upon continuing review of the trading markets for a specific
restricted security, the security may be determined to be eligible for resale to
qualified institutional buyers pursuant to Rule 144A under the Securities Act of
1933 and, therefore, to be liquid. Also, certain illiquid securities may be
determined to be liquid if they are found to satisfy certain relevant liquidity
requirements. The Board of Trustees of the Portfolio Trust and the Standish
Portfolio Trust have adopted guidelines and delegated to AAM, M&I or Standish,
as applicable, the daily function of determining and monitoring the liquidity



                                       18
<PAGE>


of portfolio securities, including restricted and illiquid securities. Each
Portfolio's Board of Trustees, however, retains oversight and is ultimately
responsible for such determinations. The purchase price and subsequent valuation
of illiquid securities normally reflect a discount, which may be significant,
from the market price of comparable securities for which a liquid market exists.

Securities Lending. Each Portfolio may lend up to 33 1/3% of their portfolio of
securities pursuant to agreements requiring that the loan be continuously
secured by cash or equivalent collateral or by a letter of credit or bank
guarantee in favor of the Portfolio at least equal at all times to 100% of the
market value plus accrued interest on the securities lent. The Portfolio will
continue to receive interest on the securities lent while simultaneously seeking
to earn interest on the investment of cash collateral. Collateral is marked to
market daily. There may be risks of delay in recovery of the securities or even
loss of rights in the collateral should the borrower of the securities fail
financially. However, loans will only be made to borrowers deemed to be of good
standing under guidelines established by the Trustees. In addition, the
Portfolio will bear the risk of any decline in value of securities acquired with
cash collateral. Loans are subject to termination by the Portfolio or the
borrower at any time and are, therefore, not considered to be illiquid
investments.

Short-Term Trading. Although the Cash Portfolio, the Treasury Plus Portfolio and
the Treasury Portfolio usually intend to hold securities purchased until
maturity, at which time they will be redeemable at their full principal value
plus accrued interest, they may, at times, engage in short-term trading to
attempt to take advantage of yield variations in the short-term market. The STAR
Portfolio may sell a portfolio security without regard to the length of time
such security has been held if, in Standish's view, the security meets certain
criteria for disposal. The Portfolios also may sell portfolio securities prior
to maturity based on a revised evaluation of the creditworthiness of the issuer
or to meet redemptions. In the event there are unusually heavy redemption
requests due to changes in interest rates or otherwise, the Portfolios may have
to sell a portion of their investment portfolio at a time when it may be
disadvantageous to do so. However, each Portfolio believes that its ability to
borrow funds to accommodate redemption requests may mitigate in part the
necessity for such portfolio sales during these periods.
    

Strategic Transactions. The STAR Portfolio may, but is not required to, utilize
various investment strategies to seek to hedge market risks (such as interest
rates, currency exchange rates and broad or specific fixed income market
movements), to manage the effective maturity or duration of fixed income
securities, or to enhance potential gain. Such strategies are generally accepted
as part of modern portfolio management and are regularly utilized by many mutual
funds and other institutional investors. Techniques and instruments used by the
STAR Portfolio may change over time as new instruments and strategies are
developed or regulatory changes occur. In the course of pursuing its investment
objective, the STAR Portfolio may purchase and sell (write) exchange-listed and
over-the-counter put and call options on securities, indices and other financial
instruments; purchase and sell financial futures contracts and options thereon;
enter into various interest rate transactions such as swaps, caps, floors or
collars; and, to the extent the STAR Portfolio invests in foreign securities,
enter into currency transactions such as forward foreign currency exchange
contracts, currency futures contracts, currency swaps and options on currencies
or currency futures (collectively, all the above are called "Strategic
Transactions"). Strategic Transactions may be used in to seek to protect against
possible changes in the market value of securities held in or to be purchased
for the STAR Portfolio's portfolio resulting from securities markets, currency
exchange rate or interest rate fluctuations, to seek to protect the STAR
Portfolio's unrealized gains in the value of portfolio securities, to facilitate
the sale of such securities for 



                                       19
<PAGE>


investment purposes, to seek to manage the effective maturity or duration of
STAR Portfolio's portfolio, or to establish a position in the derivatives
markets as a temporary substitute for purchasing or selling particular
securities. In addition to the hedging transactions referred to in the preceding
sentence, Strategic Transactions may also be used to enhance potential gain in
circumstances where hedging is not involved.

The ability of the STAR Portfolio to utilize Strategic Transactions successfully
will depend on Standish's ability to predict pertinent market and interest rate
movements, which cannot be assured. The STAR Portfolio will comply with
applicable regulatory requirements when implementing these strategies,
techniques and instruments. The STAR Portfolio's activities involving Strategic
Transactions may be limited in order to enable certain of its investors to
comply with the requirements of the Code for qualification as a regulated
investment company.

Strategic Transactions have risks associated with them including possible
default by the other party to the transaction, illiquidity and, to the extent
Standish's view as to certain market, interest rate or currency movements is
incorrect, the risk that the use of such Strategic Transactions could result in
losses greater than if they had not been used. The writing of put and call
options may result in losses to the STAR Portfolio, force the purchase or sale,
respectively, of portfolio securities at inopportune times or for prices higher
than (in the case of purchases due to the exercise of put options) or lower than
(in the case of sales due to the exercise of call options) current market
values, limit the amount of appreciation the STAR Portfolio can realize on its
investments or cause the STAR Portfolio to hold a security it might otherwise
sell.

The use of options and futures transactions entails certain other risks. Futures
markets are highly volatile and the use of futures may increase the volatility
of the STAR Portfolio's net asset value. In particular, the variable degree of
correlation between price movements of futures contracts and price movements in
the related portfolio position of the STAR Portfolio creates the possibility
that losses on the hedging instrument may be greater than gains in the value of
the STAR Portfolio's position. The writing of options could significantly
increase the STAR Portfolio's portfolio turnover rate and associated brokerage
commissions or spreads. In addition, futures and options markets may not be
liquid in all circumstances and certain over-the-counter options may have no
markets. As a result, in certain markets, the STAR Portfolio might not be able
to close out a transaction without incurring substantial losses, if at all.
Losses resulting from the use of Strategic Transactions could reduce the STAR
Portfolio's net asset value and the net result may be less favorable than if the
Strategic Transactions had not been utilized. Although the use of futures and
options transactions for hedging and managing effective maturity and duration
should tend to minimize the risk of loss due to a decline in the value of the
position, at the same time, such transactions can limit any potential gain which
might result from an increase in value of such position. The loss incurred by
the STAR Portfolio in writing options and entering into futures transactions is
potentially unlimited. The use of currency transactions can result in the STAR
Portfolio incurring losses as a result of a number of factors including the
imposition of exchange controls, suspension of settlements, or the inability to
deliver or receive a specified currency.

The STAR Portfolio will attempt to limit its net loss exposure resulting from
Strategic Transactions entered into for non-hedging purposes to 1% of its net
assets. See the SAI for further information regarding the use of Strategic
Transactions.

Temporary Defensive Investments. The STAR Portfolio may adopt a temporary
defensive position during adverse market conditions by investing without limit
in high quality money market instruments, 


                                       20
<PAGE>


including short-term U.S. Government securities, negotiable certificates of
deposit, non-negotiable fixed time deposits, bankers' acceptances, commercial
paper, floating-rate notes and repurchase agreements.

Portfolio Turnover. A high rate of portfolio turnover (100% or more) involves
correspondingly higher transaction costs which must be borne directly by a
Portfolio and thus indirectly by its shareholders. It may also result in a
Portfolio's realization of larger amounts of short-term capital gains, a Fund's
distributions from which are taxable to a Fund's shareholders as ordinary
income.

Investment Restrictions. The investment objective and investment policies set
forth in this Prospectus of the Funds and the Portfolios are not fundamental and
may be changed by their respective Board of Trustees without approval of
shareholders. Each Fund and Portfolio have also adopted fundamental policies
which may not be changed without the approval of the Fund's shareholders. See
"Investment Restrictions" in the SAI. If any percentage restriction is adhered
to at the time of investment, a subsequent increase or decrease in the
percentage resulting from a change in the value of a Portfolio's assets will not
constitute a violation of the restriction. If there is a change in a Portfolio's
or Fund's investment objective, shareholders should consider whether the Fund
remains an appropriate investment in light of their current financial situation.

                                Who Should Invest

The potential advantages offered by each Fund include large scale purchasing
power and diversification, which can help avoid the greater expense of executing
a large number of small transactions. The Funds also make it possible for
investors to participate in a more diversified portfolio than the size of the
investments might otherwise permit. Also, investment in the Funds can relieve
certain investors of many management and administrative burdens usually
associated with the direct purchase and sale of money market instruments,
including selecting portfolio investments; obtaining favorable terms at which to
buy and sell; scheduling and monitoring maturities and reinvestments;
safe-keeping of securities, and portfolio recordkeeping.

             Additional Information Concerning Investment Structure

   
Unlike other mutual funds which directly acquire and manage their own portfolio
securities, the Funds seek to achieve their investment objective by investing
all of their investable assets in their corresponding Portfolio, each of which
is, or is a series of, an open-end investment management company registered
under the 1940 Act. The Portfolios have the same investment objective and
policies as their corresponding Fund. In addition to selling its beneficial
interests to a Fund, a Portfolio may sell shares to other mutual funds,
collective investment vehicles, or institutional investors. These investors will
invest in a Portfolio on the same terms and conditions and will pay a
proportionate share of such Portfolio's expenses. However, these other investors
may be subject to different operating expenses than those of the Funds.
Therefore, investors in each Fund should be aware that these differences may
result in differences in returns experienced by institutional investors
investing directly in a Portfolio and investors investing in different funds and
other pooled investment vehicles that invest in a Portfolio. Such differences in
returns are also present in other mutual fund structures. Information concerning
other shareholders of the Portfolios can be obtained from the Funds by calling
1-888-637-7622 for the Cash Portfolio, Treasury Plus Portfolio and Treasury
Portfolio and 1-800-221-4795 for the STAR Portfolio.
    

Certain changes in a Portfolio's investment objective, policies or restrictions
may preclude its corresponding Fund from investing its investable assets in the
Portfolio and/or require the Fund to 


                                       21
<PAGE>


withdraw its interest in the Portfolio. Any such withdrawal could result in an
"in-kind" distribution of securities (as opposed to a cash distribution) from
the Portfolio. If securities are distributed, the Fund could incur brokerage,
tax or other charges in converting the securities to cash. The in-kind
distribution may result in the Fund having a less diversified portfolio of
investments or adversely affect the liquidity of the Fund. 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 a Portfolio. For example, if a large fund withdraws
from a 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 increased portfolio risk; however, these possibilities 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 a
Portfolio could have effective voting control of the operations of the
Portfolio. If a Fund is requested to vote on matters pertaining to its
corresponding 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
Fund will hold a meeting of its shareholders and will cast all of its votes
proportionately as instructed by such shareholders. A Fund 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.
Therefore, Fund shareholders who do not vote will have no effect on the outcome
of such matters.

A Fund may withdraw its investment from its corresponding Portfolio at any time,
if the Fund's Board of Trustees determines that it is in the best interest 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 of the
investable assets of the Fund in another pooled investment entity having
substantially the same investment objective as the Fund or the retaining of an
investment adviser to manage the Fund's assets in accordance with the investment
policies described above. In the event the Trustees were unable to find a
substitute investment company in which to invest the Fund's assets or were
unable to secure directly the services of an investment adviser, the Trustees
would determine the best course of action under the circumstances.

In addition, each Fund offers three classes of shares to investors, Premium
Class, Institutional Class and Investment Class shares, all three of which
represent interests in such Fund. The three classes differ in that (i) the
Institutional Class shares impose a shareholder servicing fee equal to a maximum
of 0.25% of average daily net assets of the Institutional Class shares; (ii) the
Investment Class shares impose a shareholder servicing fee and a 12b-1 fee each
equal to a maximum of 0.25% of average daily net assets of the Investment Class
shares and; (iii) the Premium Class shares charge no shareholder servicing or
12b-1 fees but require a much higher initial investment than the other classes.

                               Valuation of Shares

   
The net asset value per share of each Fund is determined each Business Day. This
determination is made once each day as of 5:00 p.m. (ET) for the Cash Series and
the Treasury Plus Series, as of 2:00 p.m. (ET) for the Treasury Series, and as
of the close of trading on the NYSE (normally 4:00 p.m. (ET)) for the STAR
Series.
    

The net asset value per share of a Fund for purposes of pricing sales and
redemptions is calculated by adding the value of all securities and other assets
of such Fund (including its interest in the corresponding Portfolio), then
subtracting the liabilities charged to the Fund, and then dividing the result by
the number of outstanding shares of the Fund.

   
The securities in the Cash Portfolio, the Treasury Plus Portfolio and the
Treasury Portfolio are valued based upon the amortized cost method which
involves valuing a security at its cost and thereafter assuming a constant
amortization to maturity of any discount or premium. Although the amortized cost
method provides consistency in valuation, it may result in periods during which
the stated value of a security is higher or lower than the price the Cash
Portfolio, Treasury Plus Portfolio or Treasury Portfolio would receive if the
security were sold. This method of valuation is used in order to stabilize the
net asset value of shares of the Cash Series, the Treasury Plus Series or the
Treasury Series at $1.00; however, there can be no assurance that a Fund's net
asset value will always remain at $1.00 per share.
    


                                       25
<PAGE>


With respect to the STAR Portfolio, the fixed income securities (other than
money market instruments) for which accurate market prices are readily available
are valued at their current market value on the basis of quotations, which may
be furnished by a pricing service or provided by dealers in such securities.
Securities not listed on an exchange or national securities market, certain
mortgage-backed and asset-backed securities and securities for which there were
no reported transactions are valued at the last quoted bid prices. Fixed income
securities for which accurate market prices are not readily available and all
other assets are valued at fair value as determined in good faith by Standish in
accordance with procedures approved by the Trustees of the Standish Portfolio
Trust, which may include the use of yield equivalents or matrix pricing. Money
market instruments with less than sixty days remaining to maturity when acquired
by the Standish Portfolio are valued on an amortized cost basis unless the
Trustees of the Standish Portfolio Trust determine that amortized cost does not
represent fair value. If the Standish Portfolio acquires a money market
instrument with more than sixty days remaining to its maturity, it is valued at
current market value until the sixtieth day prior to maturity and will then be
valued at amortized cost based upon the value on such date unless the Trustees
of the Standish Portfolio Trust determine during such sixty-day period that
amortized cost does not represent fair value.

                            Purchases and Redemptions

Purchases

General Information. Investors may purchase Fund shares only through the
Distributor which offers each Fund's shares to the public on a continuous basis.
Shares of each Fund may be purchased only in those states where they may be
lawfully sold. Shares are sold at net asset value per share next computed after
the purchase order is received in good order by the Distributor and payment for
shares is received by Investors Bank, the Funds' Custodian. See the Account
Application or call 1-888-MERRMAC for instructions on how to make payment for
shares to the Custodian.

Investment Minimum. The minimum initial investment for Premium Class shares of
the Funds is $10 million. Institutions may satisfy the minimum investment by
aggregating their fiduciary accounts. The minimum initial investment for
Institutional Class and Investment Class shares is $10,000. Subsequent purchases
may be in any amount. Each Fund reserves the right to waive the minimum initial
investment. When a Premium Class shareholder's account balance falls below $1
million due to redemption, a Fund may close the account. Such shareholders will
be notified if the minimum balance is not being maintained and will be allowed
60 days to make additional investments before the account is closed.

Class level expenses. Assets of the Premium Class shares of each Fund are not
subject to a shareholder servicing or 12b-1 fee. Assets of the Institutional
Class shares of each Fund are subject to a shareholder servicing fee of up to
0.25% of average daily net assets of the Institutional Class shares. Assets of
the Investment Class shares of each Fund are subject to a shareholder servicing
fee and 12b-1 fee each up to 0.25% of average daily net assets of the Investment
Class shares.

Share purchase orders are deemed to be in good order on the date a Fund receives
a completed Account Application (and other documents required by the Trust) and
federal funds become available to the Fund in the Fund's account with Investors
Bank.

Purchases may be made only by wire. Wiring instructions for purchases of shares
of a Fund are as follows:

                                 Amount of Wire:

   
A bank may impose a charge to execute a wire transfer. A purchaser must call
1-888-MERRMAC to inform Investors Bank of an incoming wire transfer. A purchase
order for shares received in proper form by 5:00 p.m. (ET) for the Cash Series
and the Treasury Plus Series, by 2:00 p.m. (ET) for the Treasury Series, and by
the close of trading on the NYSE (normally 4:00 p.m. (ET)), for the STAR Series,
on a Business Day will be executed at the net asset value per share next
determined after receipt of the order, provided that Investors Bank receives the
wire by the close of business on the day the purchase order is received.
Purchase orders for shares for which payment has not been received by the close
of business will not be accepted, and notice thereof will be given to the
purchaser. The Cash Series and the Treasury Plus Series also may limit the
amount of a purchase order received between 3:30 p.m. (ET) and 5:00 p.m. (ET).
    

On days when the financial markets close early, such as the day after
Thanksgiving and Christmas Eve, all purchase orders must be received by 12:00
noon (ET).

Each Fund reserves the right in its sole discretion (i) to suspend the offering
of a Fund's shares, (ii) to reject purchase orders when in the best interest of
a Fund and (iii) to modify or eliminate the minimum initial investment in Fund
shares. Purchase orders may be refused if, for example, they are of a size that
could disrupt management of a Portfolio.

Redemptions

   
Shareholders may redeem all or a portion of their shares on any Business Day.
Shares will be redeemed at the net asset value next determined after Investors
Bank has received a proper notice of redemption as described below. If notice of
redemption is received prior to 5:00 p.m. (ET) for the Cash Series and the
Treasury Plus Series, prior to 2:00 p.m. (ET) for the Treasury Series, and prior
to the close of trading on the NYSE (normally 4:00 p.m. (ET)) for the STAR
Series, on a Business Day, the redemption will be effective on the date of
receipt for the Cash Series, Treasury Plus Series and Treasury Series and on the
day following the date of receipt for the STAR series. Proceeds of the
redemption will ordinarily be made by wire on the date of receipt, but in any
event within three Business Days from the date of receipt, except for the STAR
Series wherein proceeds of the redemption will ordinarily be made by wire on the
day following the date of receipt, but in any event within four Business Days
from the date of receipt.

Shareholder redemption requests received after 5:00 p.m. (ET) for the Cash
Series and the Treasury Plus Series, after 2:00 p.m. (ET) for the Treasury
Series, and after the close of trading on the NYSE (normally 4:00 p.m. (ET)),
for the STAR Series, on a Business Day, will ordinarily receive payment by wire
on the next Business Day, but, in any event, within four Business Days from the
date of receipt of a proper notice of redemption, except for the STAR Series
wherein payment will ordinarily be received by wire on the second Business Day
after the date of receipt, but in any event within five Business Days from the
date of receipt. All redemption requests regarding shares of the Cash Series
placed between 3:00 p.m. and 5:00 p.m. (ET) may only be placed by telephone.
    


                                       27
<PAGE>


Each Fund reserves the right in its sole discretion to suspend redemptions or
postpone payments when the NYSE is closed or when trading is restricted for any
reason or under emergency circumstances as determined by the SEC. The Cash
Series and the Treasury Plus Series each reserve the right to postpone payments
for redemption requests received between 3:00 p.m. and 5:00 p.m. (ET) until the
next Business Day.

A shareholder may elect to receive payment in the form of a wire or check. There
is no charge imposed by a Fund to redeem shares; however, in the case of
redemption by wire, a shareholder's bank may impose its own wire transfer fee
for receipt of the wire.

Redemption By Wire. To redeem shares by wire, a shareholder or any authorized
agent (so designated on the Account Application) must provide Investors Bank
with the dollar amount to be redeemed, the account to which the redemption
proceeds should be wired (such account must have been previously designated by
the shareholder on its Account Application, the name of the shareholder and the
shareholder's account number.

A shareholder may change its authorized agent, the address of record or the
account designated to receive redemption proceeds at any time by writing to
Investors Bank with a signature guaranteed by a national bank which is a member
firm of any national or regional securities exchange (a "Signature Guarantee").
If the guarantor institution belongs to one of the Medallion Signature Programs,
it must use the specific Medallion "Guaranteed" stamp. Notarized signatures are
not sufficient. Further documentation may be required when Investors Bank deems
it appropriate.

Redemption By Mail. A shareholder who desires to redeem shares by mail may do so
by mailing proper notice of redemption directly to Investors Bank, ATTN:
Transfer Agency, OPS 22, P.O. Box 9130, Boston, MA 02117-9130. Proper notice of
redemption includes written notice requesting redemption along with the
signature of all persons in whose names the shares are registered, signed
exactly as the shares are registered. In certain instances, Investors Bank may
require additional documents such as trust instruments or certificates of
corporate authority. Payment will be mailed to the address of record within
seven days of receipt of a proper notice of redemption.

Telephone Redemption. A shareholder may request redemption by calling Investors
Bank at 1-888-MERRMAC. The telephone redemption option is made available to
shareholders of a Fund on the Account Application. Each Fund reserves the right
to refuse a telephone request for redemption if it believes that it is advisable
to do so. Procedures for redeeming shares by telephone may be modified or
terminated at any time by a Fund. Neither the Funds nor Investors Bank will be
liable for following redemption instructions received by telephone that are
reasonably believed to be genuine, and the shareholder will bear the risk of
loss in the event of unauthorized or fraudulent telephone instructions. Each
Fund will employ reasonable procedures to confirm that instructions communicated
by telephone are genuine. A Fund may be liable for any losses due to
unauthorized or fraudulent instructions in the absence of following these
procedures. Such procedures may include requesting personal identification
information or recording telephone conversations. Redemption checks will be made
payable to the registered shareholder(s) and sent to the address of record on
file with Investors Bank. Payments by wire will only be made to the registered
shareholder through pre-existing bank account instructions.

No bank instruction changes will be accepted over the telephone. See "Redemption
By Wire" for information on how to change bank instructions.

                       Dividends, Distributions and Taxes

Dividends and Distributions

   
Each Fund intends to declare as a dividend substantially all of its net
investment income at the close of each Business Day and will pay such dividends
monthly. Shareholders of the Cash Series, the Treasury Plus Series and the
Treasury Series shall be entitled to receive dividends on the Business Day their
purchase is effected but shall not receive dividends on the Business Day that
their redemption is effected. Shareholders of the STAR Series shall be entitled
to receive dividends on the Business Day after their purchase is effected
through the Business Day that their redemption is effected. Distributions of net
long term capital gains, if any, for the year are made annually at the
discretion of the officers of the Fund. Dividends and/or capital gain
distributions will be reinvested automatically in additional shares of a Fund at
net asset value and such shares will be automatically credited to a
shareholder's account, unless a shareholder elects to receive either dividends
or capital gains distributions (or both) in cash. Shareholders may change their
distribution option at any time by writing to Investors Bank with a Signature
Guarantee prior to the record date of any such dividend or distribution.
    

Taxes

The following summary of Federal income tax consequences is based on current tax
laws and regulations, which may be changed by legislative, judicial, or
administrative action. No attempt has been made to present a detailed
explanation of the Federal, state, or local income tax treatment of a Fund or
its shareholders. Accordingly, shareholders are urged to consult their tax
advisers regarding specific questions concerning their individual circumstances.

Tax Status of each Fund

Each Fund intends to qualify and elect to be treated as a "regulated investment
company" under the Code. If it so qualifies, a Fund will not be subject to U.S.
federal income taxes on its net investment income (i.e., its investment company
taxable income, as that term is defined in the Code, determined without regard
to the deduction for dividends paid) and net capital gain (the excess of net
realized long-term capital gain over net realized short-term capital loss), if
any, that it distributes to its shareholders in each taxable year, provided that
it distributes to its shareholders at least 90% of the sum of its net investment
income and any net tax-exempt interest for such taxable year. If in any year a
Fund fails to qualify as a regulated investment company, the Fund would incur
regular corporate federal income tax on its taxable income for that year and be
subject to certain additional distribution requirements upon requalification.

Each Fund is subject to a nondeductible 4% excise tax calculated as a percentage
of certain undistributed amounts of ordinary income and capital gain net income.
To the extent possible, each Fund intends to make sufficient distributions to
avoid the application of both the corporate income and excise taxes.

Tax Status of Distributions


                                       29
<PAGE>


All dividends and distributions to shareholders of each Fund of investment
company taxable income will be taxable to shareholders whether paid in cash or
reinvested in additional shares. For federal income tax purposes, distributions
of net investment income, which includes the excess of a Fund's net realized
short-term capital gain over its net realized long-term capital loss, are
taxable to shareholders as ordinary income.

Distributions of net realized long-term capital gains designated by a Fund as
"capital gain dividends" will be taxable as long-term capital gains, whether
paid in cash or additional shares, regardless of how long the shares have been
held by such shareholders, capital gain dividends will not, and the Funds'
distributions of net investment income generally will not, be eligible for the
corporate dividends received deduction. For shareholders other than
corporations, long-term capital gain dividends currently are taxed at more
favorable federal income tax rates than ordinary income and short-term capital
gains. Recent changes in federal tax law, as applied to a Fund, allow for
capital gain dividends to be taxed to such shareholders at maximum rates of 20%
or 28%.

   
Gain or loss, if any, recognized on the sale or other disposition of shares of a
Fund will be taxed as capital gain or loss if the shares are capital assets in
the shareholder's hands and the transaction is treated as a sale for tax
purposes. Since the Cash Series, the Treasury Plus Series and the Treasury
Series attempt to maintain a stable net asset value of $1.00 per share, it is
anticipated that gain or loss would generally not result upon dispositions of
the shares of these Funds. Generally, a shareholder's gain or loss, if any, will
be a long term gain or loss if the shares have been held for more than one year,
although a holding period greater than eighteen months will be necessary in
order to benefit from the lowest capital gain tax rate currently in effect for
noncorporate shareholders. If a shareholder sells or otherwise disposes of
shares of a Fund before holding them for more than six months, any loss on the
sale or other disposition of such shares will be treated as a long-term capital
loss to the extent of any capital gain dividends received by the shareholder
with respect to such shares. A loss realized on a sale or exchange of shares may
be disallowed if other shares are acquired within a 61-day period beginning 30
days before and ending 30 days after the date that the shares are sold.
    

                             Performance Information

From time to time performance may be quoted in shareholder reports,
advertisements and other communications to shareholders or in other materials in
terms of yield, effective yield and average annual total return. Performance
figures are based upon historical earnings and are not intended to indicate
future performance.

   
The "yield" of the Treasury Series, the Treasury Plus Series and the Cash Series
refers to income generated by an investment in such Fund over a seven-day
period, which period will be stated in the advertisement. This income is then
annualized, which means that the income generated during the seven-day period is
assumed to be generated each week over a 52-week period and is shown as a
percentage of the investment. "Effective yield" of the Cash Series, the Treasury
Plus Series or Treasury Series is calculated similarly to the yield, but the
income earned by the investment is assumed to be compounded weekly when
annualized. Effective yield will be slightly higher than yield due to this
compounding effect.

The "yield" of the STAR Series is computed by dividing the net investment income
per share earned during the period (generally 30 days or one month) stated in
the advertisement by the maximum offering 


                                       30
<PAGE>


price per share on the last day of the period (using the average number of
shares entitled to receive dividends).
    

In determining net investment income for purposes of calculating yield and
effective yield of any Fund, the calculation includes among expenses of the Fund
all recurring fees that are charged to all shareholder accounts and any
recurring charges for the period stated.

Average annual total return is determined by computing the average annual
percentage change in the value of $1,000 invested at the maximum public offering
price for specified periods ending with the most recent calendar quarter,
assuming reinvestment of all dividends and distributions at net asset value. The
total return calculation assumes a complete redemption of the investment at the
end of the relevant period. The Funds may also from time to time advertise total
return on a cumulative, average, year-by-year or other basis for various
specified periods by means of quotations, charts, graphs or schedules.

In reports or other communications to shareholders or in other materials,
performance of each class of a Fund may be compared with that of other mutual
funds tracked by mutual fund rating services, to broad groups of comparable
mutual funds or to unmanaged indices that may assume investment of dividends but
generally do not reflect deductions for administrative and management costs.
Additional performance information is also available in a Fund's Annual and
Semi-Annual Reports, which are sent to all shareholders and which can be
obtained without charge from each Fund by calling 1-888-MERRMAC.

                Additional Information About Investment Policies

   
The Merrimac Series (the "Trust"), an open-end management investment company,
consists of the following series: the Merrimac Cash Series (the "Cash Series"),
the Merrimac Treasury Plus Series (the "Treasury Plus Series"), the Merrimac
Treasury Series (the "Treasury Series"), and the Merrimac Short-Term Asset
Reserve Series (the "STAR Series") (each, a "Fund" and collectively, the
"Funds").

Unlike other mutual funds which directly acquire and manage their own portfolios
of securities, the Funds seek to achieve their investment objective by investing
all of their investable assets in the Merrimac Cash Portfolio (the "Cash
Portfolio"), the Merrimac Treasury Plus Portfolio (the "Treasury Plus
Portfolio") the Merrimac Treasury Portfolio (the "Treasury Portfolio"), and the
Standish Short-Term Asset Reserve Portfolio (the "STAR Portfolio") (hereinafter
each, a "Portfolio", and collectively, the "Portfolios"). The Cash Portfolio,
the Treasury Plus Portfolio and the Treasury Portfolio are each a series of the
Merrimac Master Portfolio (the "Portfolio Trust"), a separate open-end
management investment company. The STAR Portfolio is a series of the Standish,
Ayer & Wood Master Portfolio (the "Standish Portfolio Trust"), also a separate
open-end management investment company. Each Portfolio has the same investment
objective and policies as its corresponding Fund. The Funds offer Premium,
Institutional and Investment Class shares.
    

The information below supplements the information set forth in the Prospectus
under "Investment Objectives and Policies" and "Description of Permitted
Investments and Related Risks." Since the investment characteristics of the
Funds correspond directly to those of their corresponding Portfolio, the
following discusses the various investment techniques employed by each
Portfolio.

Maturity and Duration. The effective maturity of an individual portfolio
security in which the STAR Portfolio invests is defined as the period remaining
until the earliest date when the Portfolio can recover the principal amount of
such security through mandatory redemption or prepayment by the issuer, the
exercise by the Portfolio of a put option, demand feature or tender option
granted by the issuer or a third party or the payment of the principal on the
stated maturity date. The effective maturity of variable rate securities is
calculated by reference to their coupon reset dates. Thus, the effective
maturity of a security may be substantially shorter than its final stated
maturity. Unscheduled prepayments of principal have the effect of shortening the
effective maturities of securities in general and mortgage-backed securities in
particular. Prepayment rates are influenced by changes in current interest rates
and a variety of economic, geographic, social and other factors and cannot be
predicted with certainty. In general, securities, such as mortgage-backed
securities, may be subject to greater prepayment rates in a declining interest
rate environment. Conversely, in an increasing interest rate environment, the
rate of prepayment may be expected to decrease. A higher than anticipated rate
of unscheduled principal prepayments on securities purchased at a premium or a
lower than anticipated rate of unscheduled payments on securities purchased at a
discount may result in a lower yield (and total return) to the Portfolio than
was anticipated at the time the securities were purchased. The Portfolio's
reinvestment of 


                                       2
<PAGE>


unscheduled prepayments may be made at rates higher or lower than the rate
payable on such security, thus affecting the return realized by the Portfolio.

Duration of an individual portfolio security is a measure of the security's
price sensitivity taking into account expected cash flow and prepayments under a
wide range of interest rate scenarios. In computing the duration of its
portfolio, the Portfolio will have to estimate the duration of obligations that
are subject to prepayment or redemption by the issuer taking into account the
influences of interest rates on prepayments and coupon flows. The STAR Portfolio
may use various techniques to shorten or lengthen the option-adjusted duration
of its portfolio, including the acquisition of debt obligations at a premium or
discount, the use of mortgage swaps and interest rate swaps, caps, floors and
collars.

   
Money Market Instruments and Repurchase Agreements. The money market instruments
in which the Cash Portfolio, Treasury Plus Portfolio and STAR Portfolio invest,
include short-term U.S. Government securities (defined below), commercial paper
(promissory notes issued by corporations to finance their short-term credit
needs), negotiable certificates of deposit, non-negotiable fixed time deposits,
bankers' acceptances and repurchase agreements. The Treasury Portfolio invests
only in direct obligations of the U.S. Treasury and the Treasury Plus Portfolio
invests substantially all of its assets in direct obligations of the U.S.
Treasury in U.S. Government Securities and in repurchase agreements.
    

U.S. Government Securities include securities which are direct obligations of
the U.S. Government backed by the full faith and credit of the United States,
and securities issued by agencies and instrumentalities of the U.S. Government,
which may be guaranteed by the U.S. Treasury or supported by the issuer's right
to borrow from the U.S. Treasury or may be backed by the credit of the federal
agency or instrumentality itself. Agencies and instrumentalities of the U.S.
Government include, but are not limited to, Federal Land Banks, the Federal Farm
Credit Bank, the Central Bank for Cooperatives, Federal Intermediate Credit
Banks, Federal Home Loan Banks and the Federal National Mortgage Association.

A repurchase agreement is an agreement under which a Portfolio acquires money
market instruments (generally U.S. Government Securities) from a commercial
bank, broker or dealer, subject to resale to the seller at an agreed-upon price
and date (normally the next business day). The resale price reflects an
agreed-upon interest rate effective for the period the instruments are held by a
Portfolio and is unrelated to the interest rate on the instruments. The
instruments acquired by a Portfolio (including accrued interest) must have an
aggregate market value in excess of the resale price and will be held by the
custodian bank for the Portfolio until they are repurchased. The Board of
Trustees of the Portfolio Trust and the Standish Portfolio Trust will monitor
the standards that the investment adviser or sub-adviser will use in reviewing
the creditworthiness of any party to a repurchase agreement with a Portfolio.
See "Investment Advisory Services" for information regarding the investment
adviser and sub-adviser.

The use of repurchase agreements involves certain risks. For example, if the
seller defaults on its obligation to repurchase the instruments acquired by a
Portfolio at a time when their market value has declined, a Portfolio may incur
a loss. If the seller becomes insolvent or subject to liquidation or
reorganization under bankruptcy or other laws, a court may determine that the


                                       3
<PAGE>


instruments acquired by a Portfolio are collateral for a loan by a Portfolio and
therefore are subject to sale by the trustee in bankruptcy. Finally, it is
possible that a Portfolio may not be able to substantiate its interest in the
instruments it acquires. It is expected that these risks can be controlled
through careful documentation and monitoring.

Structured or Hybrid Notes. As more fully described in the Prospectus, the STAR
Portfolio may invest in structured or hybrid notes. It is expected that not more
than 5% of the Portfolio's net assets will be at risk as a result of such
investments. In addition to the risks associated with a direct investment in the
benchmark asset, investments in structured and hybrid notes involve the risk
that the issuer or counterparty to the obligation will fail to perform its
contractual obligations. Certain structured or hybrid notes may also be
leveraged to the extent that the magnitude of any change in the interest rate or
principal payable on the benchmark asset is a multiple of the change in the
reference price. Leverage enhances the price volatility of the security and,
therefore, the Portfolio's net asset value ("NAV"). Further, certain structured
or hybrid notes may be illiquid for purposes of the STAR Portfolio's limitation
on investments in illiquid securities.

Mortgage-Related Obligations. The STAR Portfolio may invest in mortgage-related
obligations. Some of the characteristics of mortgage-related obligations and the
issuers or guarantors of such securities are described below.

Life of Mortgage-Related Obligations. The average life of mortgage-related
obligations is likely to be substantially less than the stated maturities of the
mortgages in the mortgage pools underlying such securities. Prepayments or
refinancing of principal by mortgagors and mortgage foreclosures will usually
result in the return of the greater part of the principal invested long before
the maturity of the mortgages in the pool.

As prepayment rates of individual mortgage pools will vary widely, it is not
possible to predict accurately the average life of a particular issue of
mortgage-related obligations. However, with respect to GNMA Certificates,
statistics published by the FHA are normally used as an indicator of the
expected average life of an issue. The actual life of a particular issue of GNMA
Certificates, however, will depend on the coupon rate of the financing.

GNMA Certificates. The Government National Mortgage Association ("GNMA") was
established in 1968 when the Federal National Mortgage Association ("FNMA") was
separated into two organizations, GNMA and FNMA. GNMA is a wholly-owned
government corporation within the Department of Housing and Urban Development.
GNMA developed the first mortgage-backed pass-through instruments in 1970 for
Farmers Home Administration-FHMA-insured, Federal Housing
Administration-FHA-insured and for Veterans Administration- or VA-guaranteed
mortgages ("government mortgages").

GNMA purchases government mortgages and occasionally conventional mortgages to
support the housing market. GNMA is known primarily, however, for its role as
guarantor of pass-through securities collateralized by government mortgages.
Under the GNMA securities guarantee program, government mortgages that are
pooled must be less than one year old by the 


                                       4
<PAGE>


date GNMA issues its commitment. Loans in a single pool must be of the same type
in terms of interest rate and maturity. The minimum size of a pool is $1 million
for single-family mortgages and $500,000 for manufactured housing and project
loans.

Under the GNMA II program, loans with different interest rates can be included
in a single pool and mortgages originated by more than one lender can be
assembled in a pool. In addition, loans made by a single lender can be packaged
in a custom pool (a pool containing loans with specific characteristics or
requirements).

GNMA Guarantee. The National Housing Act authorizes GNMA to guarantee the timely
payment of principal of and interest on securities backed by a pool of mortgages
insured by FHA or FHMA, or guaranteed by VA. The GNMA guarantee is backed by the
full faith and credit of the United States. GNMA is also empowered to borrow
without limitation from the U.S. Treasury if necessary to make any payments
required under its guarantee.

Yield Characteristics of GNMA Certificates. The coupon rate of interest on GNMA
Certificates is lower than the interest rate paid on the VA-guaranteed,
FHMA-insured or FHA-insured mortgages underlying the Certificates, but only by
the amount of the fees paid to GNMA and the issuer. For the most common type of
mortgage pool, containing single-family dwelling mortgages, GNMA receives an
annual fee of 0.06% of the outstanding principal for providing its guarantee,
and the issuer is paid an annual fee of 0.44% for assembling the mortgage pool
and for passing through monthly payments of interest and principal to GNMA
Certificate holders.

The coupon rate by itself, however, does not indicate the yield which will be
earned on the GNMA Certificates for several reasons. First, GNMA Certificates
may be issued at a premium or discount, rather than at par, and, after issuance,
GNMA Certificates may trade in the secondary market at a premium or discount.
Second, interest is paid monthly, rather than semi-annually as with traditional
bonds. Monthly compounding has the effect of raising the effective yield earned
on GNMA Certificates. Finally, the actual yield of each GNMA Certificate is
influenced by the prepayment experience of the mortgage pool underlying the GNMA
Certificate. If mortgagors prepay their mortgages, the principal returned to
GNMA Certificateholders may be reinvested at higher or lower rates.

Market for GNMA Certificates. Since the inception of the GNMA mortgage-backed
securities program in 1970, the amount of GNMA Certificates outstanding has
grown rapidly. The size of the market and the active participation in the
secondary market by securities dealers and many types of investors make the GNMA
Certificates a highly liquid instrument. Prices of GNMA Certificates are readily
available from securities dealers and depend on, among other things, the level
of market rates, the GNMA Certificate's coupon rate and the prepayment
experience of the pools of mortgages backing each GNMA Certificate.

FHLMC Participation Certificates. The Federal Home Loan Mortgage Corporation
("FHLMC") was created by the Emergency Home Finance Act of 1970. It is a private
corporation, initially capitalized by the Federal Home Loan Bank System, charged
with supporting the mortgage lending activities of savings and loan associations
by providing an 


                                       5
<PAGE>


active secondary market for conventional mortgages. To finance its mortgage
purchases, FHLMC issues FHLMC Participation Certificates and Collateralized
Mortgage Obligations ("CMOs").

Participation Certificates represent an undivided interest in a pool of mortgage
loans. FHLMC purchases whole loans or participations in 30-year and 15-year
fixed rate mortgages, adjustable-rate mortgages ("ARMs") and home improvement
loans. Under certain programs, it will also purchase FHA and VA mortgages.

Loans pooled for FHLMC must have a minimum coupon rate equal to the
Participation Certificate rate specified at delivery, plus a required spread for
the corporation and a minimum servicing fee, generally 0.375% (37.5 basis
points). The maximum coupon rate on loans is 2% (200 basis points) in excess of
the minimum eligible coupon rate for Participation Certificates. FHLMC requires
a minimum commitment of $1 million in mortgages but imposes no maximum amount.
Negotiated deals require a minimum commitment of $10 million. FHLMC guarantees
timely payment of the interest and the ultimate payment of principal of its
Participation Certificates. This guarantee is backed by reserves set aside to
protect against losses due to default. The FHLMC CMO is divided into varying
maturities with prepayment set specifically for holders of the shorter term
securities. The CMO is designed to respond to investor concerns about early
repayment of mortgages.

FHLMC's CMOs are general obligations, and FHLMC will be required to use its
general funds to make principal and interest payments on CMOs if payments
generated by the underlying pool of mortgages are insufficient to pay principal
and interest on the CMO.

A CMO is a cash-flow bond in which mortgage payments from underlying mortgage
pools pay principal and interest to CMO bondholders. The CMO is structured to
address two major short-comings associated with traditional pass-through
securities: payment frequency and prepayment risk. Traditional pass-through
securities pay interest and amortized principal on a monthly basis whereas CMOs
normally pay principal and interest semi-annually. In addition, mortgage-backed
securities carry the risk that individual mortgagors in the mortgage pool may
exercise their prepayment privileges, leading to irregular cash flow and
uncertain average lives, durations and yields.

A typical CMO structure contains four tranches, which are generally referred to
as Classes A, B, C and Z. Each tranche is identified by its coupon and maturity.
The first three classes are usually current interest-bearing bonds paying
interest on a quarterly or semi-annual basis, while the fourth, Class Z, is an
accrual bond. Amortized principal payments and prepayments from the underlying
mortgage collateral redeem principal of the CMO sequentially; payments from the
mortgages first redeem principal on the Class A bonds. When principal of the
Class A bonds has been redeemed, the payments then redeem principal on the Class
B bonds. This pattern of using principal payments to redeem each bond
sequentially continues until the Class C bonds have been retired. At this point,
Class Z bonds begin paying interest and amortized principal on their accrued
value.


                                       6
<PAGE>


The final tranche of a CMO is usually a deferred interest bond, commonly
referred to as the Z bond. This bond accrues interest at its coupon rate but
does not pay this interest until all previous tranches have been fully retired.
While earlier classes remain outstanding, interest accrued on the Z bond is
compounded and added to the outstanding principal. The deferred interest period
ends when all previous tranches are retired, at which point the Z bond pays
periodic interest and principal until it matures. The Adviser would purchase a Z
bond for the STAR Portfolio if it expected interest rates to decline.

FNMA Securities. FNMA was created by the National Housing Act of 1938. In 1968,
the agency was separated into two organizations, GNMA to support a secondary
market for government mortgages and FNMA to act as a private corporation
supporting the housing market.

FNMA pools may contain fixed-rate conventional loans on one-to-four-family
properties. Seasoned FHA and VA loans, as well as conventional growing equity
mortgages, are eligible for separate pools. FNMA will consider other types of
loans for securities pooling on a negotiated basis. A single pool may include
mortgages with different loan-to-value ratios and interest rates, though rates
may not vary beyond two percentage points.

Privately-Issued Mortgage Loan Pools. Savings associations, commercial banks and
investment bankers issue pass-through securities secured by a pool of mortgages.

Generally, only conventional mortgages on single-family properties are included
in private issues, though seasoned loans and variable rate mortgages are
sometimes included. Private placements allow purchasers to negotiate terms of
transactions. Maximum amounts for individual loans may exceed the loan limit set
for government agency purchase. Pool size may vary, but the minimum is usually
$20 million for public offerings and $10 million for private placements.

Privately-issued mortgage-related obligations do not carry government or
quasi-government guarantees. Rather, mortgage pool insurance generally is used
to insure against credit losses that may occur in the mortgage pool. Pool
insurance protects against credit losses to the extent of the coverage in force.
Each mortgage, regardless of original loan-to-value ratio, is insured to 100% of
principal, interest and other expenses, to a total aggregate loss limit stated
on the policy. The aggregate loss limit of the policy generally is 5% to 7% of
the original aggregate principal of the mortgages included in the pool.

In addition to the insurance coverage to protect against defaults on the
underlying mortgages, mortgage-backed securities can be protected against the
nonperformance or poor performance of servicers. Performance bonding of
obligations such as those of the servicers under the origination, servicing or
other contractual agreement will protect the value of the pool of insured
mortgages and enhance the marketability.

The rating received by a mortgage security will be a major factor in its
marketability. For public issues, a rating is always required, but it may be
optional for private placements depending on the demands of the marketplace and
investors.


                                       7
<PAGE>


Before rating an issue, a nationally recognized statistical rating organization
such as Standard & Poor's Rating Group ("Standard & Poor's"), Moody's Investors
Service, Inc. ("Moody's"), Fitch's Investors Service ("Fitch"), Duff and Phelps
("Duff") or IBCA Limited ("IBCA") will consider several factors, including: the
creditworthiness of the issuer; the issuer's track record as an originator and
servicer; the type, term and characteristics of the mortgages, as well as
loan-to-value ratio and loan amounts; the insurer and the level of mortgage
insurance and hazard insurance provided. Where an equity reserve account or
letter of credit is offered, the rating agency will also examine the adequacy of
the reserve and the strength of the issuer of the letter of credit.

Strategic Transactions. The STAR Portfolio may, but is not required to, utilize
various other investment strategies as described below to seek to hedge various
market risks (such as interest rates and broad or specific fixed-income market
movements), to manage the effective maturity or duration of fixed-income
securities, or to enhance potential gain. Such strategies are generally accepted
as part of modern portfolio management and are regularly utilized by many mutual
funds and other institutional investors. Techniques and instruments used by the
STAR Portfolio may change over time as new instruments and strategies are
developed or regulatory changes occur.

In the course of pursuing its investment objective, the STAR Portfolio may
purchase and sell (write) exchange-listed and over-the-counter put and call
options on securities, indices and other financial instruments; purchase and
sell financial futures contracts and options thereon; and enter into various
interest rate transactions such as swaps, caps, floors or collars (collectively,
all the above are called "Strategic Transactions"). Strategic Transactions may
be used to seek to protect against possible changes in the market value of
securities held in or to be purchased for the STAR Portfolio's portfolio
resulting from securities market or interest rate fluctuations, to protect the
STAR Portfolio's unrealized gains in the value of its portfolio securities, to
facilitate the sale of such securities for investment purposes, to manage the
effective maturity or duration of the STAR Portfolio's portfolio, or to
establish a position in the derivatives markets as a temporary substitute for
purchasing or selling particular securities.

In addition to the hedging transactions referred to in the preceding paragraph,
Strategic Transactions may also be used by the STAR Portfolio to seek to enhance
potential gain in circumstances where hedging is not involved although the STAR
Portfolio will attempt to limit its net loss exposure resulting from Strategic
Transactions entered into for such purposes to not more than 1% of its net
assets at any one time and, to the extent necessary, the STAR Portfolio will
close out transactions in order to comply with this limitation. (Transactions
such as writing covered call options are considered to involve hedging for the
purposes of this limitation.) In calculating the STAR Portfolio's net loss
exposure from such Strategic Transactions, an unrealized gain from a particular
Strategic Transaction position would be netted against an unrealized loss from a
related Strategic Transaction position. For example, if the STAR Portfolio's
Adviser believes that short-term interest rates as indicated in the forward
yield curve are too high, the STAR Portfolio may take a short position in a
near-term Eurodollar futures contract and a long position in a longer-dated
Eurodollar futures contract. Under such 


                                       8
<PAGE>


circumstances, any unrealized loss in the near-term Eurodollar futures position
would be netted against any unrealized gain in the near-term Eurodollar futures
position (and vice versa) for purposes of calculating the STAR Portfolio's net
loss exposure.

The ability of the STAR Portfolio to utilize these Strategic Transactions
successfully will depend on its Adviser's ability to predict pertinent market
and interest rate movements, which cannot be assured. The STAR Portfolio will
comply with applicable regulatory requirements when implementing these
strategies, techniques and instruments. The STAR Portfolio's activities
involving Strategic Transactions may be limited by the requirements of
Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code"), that
apply to investors in the STAR Portfolio that intend to qualify as regulated
investment companies.

Risks of Strategic Transactions. The use of Strategic Transactions by the STAR
Portfolio has associated risks including possible default by the other party to
the transaction, illiquidity and, to the extent its Adviser's view as to certain
market or interest rate movements is incorrect, the risk that the use of such
Strategic Transactions could result in losses greater than if they had not been
used. Writing put and call options may result in losses to the STAR Portfolio,
force the purchase or sale, respectively, of portfolio securities at inopportune
times or for prices higher than (in the case of purchases due to the exercise of
put options) or lower than (in the case of sales due to the exercise of call
options) current market values, limit the amount of appreciation the STAR
Portfolio can realize on its investments or cause the STAR Portfolio to hold a
security it might otherwise sell.

The use of options and futures transactions entails certain other risks. In
particular, the variable degree of correlation between price movements of
futures contracts and price movements in the related portfolio position of the
STAR Portfolio creates the possibility that losses on the hedging instrument may
be greater than gains in the value of the STAR Portfolio's position. Writing
options could significantly increase the STAR Portfolio's portfolio turnover
rate and, therefore, associated brokerage commissions or spreads. In addition,
futures and options markets may not be liquid in all circumstances and certain
over-the-counter options may have no markets. As a result, in certain markets,
the STAR Portfolio might not be able to close out a transaction without
incurring substantial losses, if at all. Although the use of futures and options
transactions for hedging should tend to minimize the risk of loss due to a
decline in the value of the hedged position, at the same time, in certain
circumstances, they tend to limit any potential gain which might result from an
increase in value of such position.

The loss incurred by the STAR Portfolio in writing options on futures and
entering into futures transactions is potentially unlimited; however, as
described above, the STAR Portfolio will attempt to limit its net loss exposure
resulting from Strategic Transactions entered into for non-hedging purposes to
not more than 1% of its net assets at any one time. Futures markets are highly
volatile and the use of futures may increase the volatility of the STAR
Portfolio's NAV . Finally, entering into futures contracts would create a
greater ongoing potential financial risk than would purchases of options where
the exposure is limited to the cost of the initial premium. Losses resulting
from the use of Strategic Transactions would reduce NAV and the net result may
be less favorable than if the Strategic Transactions had not been utilized.

General Characteristics of Options. Put options and call options typically have
similar structural characteristics and operational mechanics regardless of the
underlying instrument on which they are purchased or sold. Thus, the following
general discussion relates to each of the particular types of options discussed
in greater detail below. In addition, many Strategic Transactions involving
options require segregation of the STAR Portfolio's assets in special accounts,
as described below under "Use of Segregated Accounts."

A put option gives the purchaser of the option, in consideration for the payment
of a premium, the right to sell, and the writer the obligation to buy (if the
option is exercised), the underlying security, commodity, index or other
instrument at the exercise price. For instance, the STAR Portfolio's purchase of
a put option on a security might be designed to protect its holdings in the
underlying instrument (or, in some cases, a similar instrument) against a
substantial decline in the market value by giving the STAR Portfolio the right
to sell such instrument at the option exercise price. A call option, in
consideration for the payment of a premium, gives the purchaser of the option
the right to buy, and the seller the obligation to sell (if the option is
exercised), the underlying instrument at the exercise price. The STAR Portfolio
may purchase a call option on a security, futures contract, index or other
instrument to seek to protect the STAR Portfolio against an increase in the
price of the underlying instrument that it intends to purchase in the future by
fixing the price at which it may purchase such instrument. An American style put
or call option may be exercised at any time during the option period while a
European style put or call option may be exercised only upon expiration or
during a fixed period prior thereto. The STAR Portfolio is authorized to
purchase and sell exchange listed options and over-the-counter options ("OTC
options"). Exchange listed options are issued by a regulated intermediary such
as the Options Clearing Corporation ("OCC"), which guarantees the performance of
the obligations of the parties to such options. The discussion below uses the
OCC as an example, but is also applicable to other financial intermediaries.

With certain exceptions, exchange listed options generally settle by physical
delivery of the underlying security, although in the future cash settlement may
become available. Index options and Eurodollar instruments are cash settled for
the net amount, if any, by which the option is "in-the-money" (i.e., where the
value of the underlying instrument exceeds, in the case of a call option, or is
less than, in the case of a put option, the exercise price of the option) at the
time the option is exercised. Frequently, rather than taking or making delivery
of the underlying instrument through the process of exercising the option,
listed options are closed by entering into offsetting purchase or sale
transactions that do not result in ownership of the new option.

The STAR Portfolio's ability to close out its position as a purchaser or seller
of an exchange listed put or call option is dependent, in part, upon the
liquidity of the option market. There is no assurance that a liquid option
market on an exchange will exist. In the event that the relevant market for an
option on an exchange ceases to exist, outstanding options on that exchange
would generally continue to be exercisable in accordance with their terms.

The hours of trading for listed options may not coincide with the hours during
which the underlying financial instruments are traded. To the extent that the
option markets close before the  


                                       10
<PAGE>


markets for the underlying financial instruments, significant price and rate
movements can take place in the underlying markets that cannot be reflected in
the option markets.

OTC options are purchased from or sold to securities dealers, financial
institutions or other parties ("Counterparties") through direct agreement with
the Counterparty. In contrast to exchange listed options, which generally have
standardized terms and performance mechanics, all the terms of an OTC option,
including such terms as method of settlement, term, exercise price, premium,
guarantees and security, are set by negotiation of the parties. The STAR
Portfolio will generally sell (write) OTC options that are subject to a buy-back
provision permitting the STAR Portfolio to require the Counterparty to sell the
option back to the STAR Portfolio at a formula price within seven days. OTC
options purchased by the STAR Portfolio, and portfolio securities "covering" the
amount of the STAR Portfolio's obligation pursuant to an OTC option sold by it
(the cost of the sell-back plus the in-the-money amount, if any) are subject to
the STAR Portfolio's restriction on illiquid securities, unless determined to be
liquid in accordance with procedures adopted by the Board of Trustees of the
Standish Portfolio Trust. For OTC options written with "primary dealers"
pursuant to an agreement requiring a closing purchase transaction at a formula
price, the amount which is considered to be illiquid may be calculated by
reference to a formula price. The STAR Portfolio expects generally to enter into
OTC options that have cash settlement provisions, although it is not required to
do so.

Unless the parties provide for it, there is no central clearing or guaranty
function in the OTC option market. As a result, if the Counterparty fails to
make delivery of the security, currency or other instrument underlying an OTC
option it has entered into with the STAR Portfolio or fails to make a cash
settlement payment due in accordance with the terms of that option, the STAR
Portfolio will lose any premium it paid for the option as well as any
anticipated benefit of the transaction. Accordingly, the STAR Portfolio's
Adviser must assess the creditworthiness of each such Counterparty or any
guarantor or credit enhancement of the Counterparty's credit to determine the
likelihood that the terms of the OTC option will be satisfied. The STAR
Portfolio will engage in OTC option transactions only with U.S. Government
securities dealers recognized by the Federal Reserve Bank of New York as
"primary dealers," or broker-dealers, domestic or foreign banks or other
financial institutions which have received, combined with any credit
enhancements, a long-term debt rating of A from Standard and Poor's or Moody's
or an equivalent rating from any other nationally recognized statistical rating
organization ("NRSRO") or which issue debt that is determined to be of
equivalent credit quality by the STAR Portfolio's Adviser.

If the STAR Portfolio sells (writes) a call option, the premium that it receives
may serve as a partial hedge, to the extent of the option premium, against a
decrease in the value of the underlying securities or instruments in its
portfolio or will increase the STAR Portfolio's income. The sale (writing) of
put options can also provide income.

The STAR Portfolio may purchase and sell (write) put and call options on
securities, including U.S. Treasury and agency securities and Eurodollar
instruments that are traded on U.S. and foreign securities exchanges and in the
OTC markets and on securities indices and futures contracts.


                                       11
<PAGE>


All calls sold by the STAR Portfolio must be "covered" (i.e., the STAR Portfolio
must own the securities or the futures contract subject to the call) or must
meet the asset segregation requirements described below as long as the call is
outstanding. In addition, the STAR Portfolio may cover a written call option or
put option by entering into an offsetting forward contract and/or by purchasing
an offsetting option or any other option which, by virtue of its exercise price
or otherwise, reduces the STAR Portfolio's net exposure on its written option
position. Even though the STAR Portfolio will receive the option premium to help
offset any loss, the STAR Portfolio may incur a loss if the exercise price is
below the market price for the security subject to the call at the time of
exercise. A call sold by the STAR Portfolio also exposes the Portfolio during
the term of the option to possible loss of opportunity to realize appreciation
in the market price of the underlying security or instrument and may require the
STAR Portfolio to hold a security or instrument which it might otherwise have
sold.

The STAR Portfolio will not sell put options if, as a result, more than 50% of
the STAR Portfolio's assets would be required to be segregated to cover its
potential obligations under such put options other than those with respect to
futures and options thereon. In selling put options, there is a risk that the
STAR Portfolio may be required to buy the underlying security at a price above
the market price.

Options on Securities Indices and Other Financial Indices. The STAR Portfolio
may also purchase and sell (write) call and put options on securities indices
and other financial indices. Options on securities indices and other financial
indices are similar to options on a security or other instrument except that,
rather than settling by physical delivery of the underlying instrument, they
settle by cash settlement. For example, an option on an index gives the holder
the right to receive, upon exercise of the option, an amount of cash if the
closing level of the index upon which the option is based exceeds, in the case
of a call, or is less than, in the case of a put, the exercise price of the
option (except if, in the case of an OTC option, physical delivery is
specified). This amount of cash is equal to the differential between the closing
price of the index and the exercise price of the option, which also may be
multiplied by a formula value. The seller of the option is obligated, in return
for the premium received, to make delivery of this amount upon exercise of the
option. In addition to the methods described above, the STAR Portfolio may cover
call options on a securities index by owning securities whose price changes are
expected to be similar to those of the underlying index, or by having an
absolute and immediate right to acquire such securities without additional cash
consideration (or for additional cash consideration held in a segregated account
by its custodian) upon conversion or exchange of other securities in its
portfolio.

General Characteristics of Futures. The STAR Portfolio may enter into financial
futures contracts or purchase or sell put and call options on such futures.
Futures are generally bought and sold on the commodities exchanges where they
are listed and involve payment of initial and variation margin as described
below. All futures contracts entered into by the STAR Portfolio are traded on
U.S. exchanges or boards of trade that are licensed and regulated by the
Commodity Futures Trading Commission ("CFTC") or on certain foreign exchanges.
The sale of futures contracts creates a firm obligation by the STAR Portfolio,
as seller, to deliver to the buyer the 


                                       12
<PAGE>


specific type of financial instrument called for in the contract at a specific
future time for a specified price (or, with respect to index futures and
Eurodollar instruments, the net cash amount). The purchase of futures contracts
creates a corresponding obligation by the STAR Portfolio, as purchaser, to
purchase a financial instrument at a specific time and price. Options on futures
contracts are similar to options on securities except that an option on a
futures contract gives the purchaser the right in return for the premium paid to
assume a position in a futures contract and obligates the seller to deliver such
position upon exercise of the option.

The STAR Portfolio's use of financial futures and options thereon will in all
cases be consistent with applicable regulatory requirements and in particular
the regulations of the CFTC relating to exclusions from regulation as a
commodity pool operator. Those regulations currently provide that the STAR
Portfolio may use commodity futures and option positions (i) for bona fide
hedging purposes without regard to the percentage of assets committed to margin
and option premiums, or (ii) for other purposes permitted by the CFTC to the
extent that the aggregate initial margin and option premiums required to
establish such non-hedging positions (net of the amount that the positions were
"in the money" at the time of purchase) do not exceed 5% of the NAV of the STAR
Portfolio's portfolio, after taking into account unrealized profits and losses
on such positions. Typically, maintaining a futures contract or selling an
option thereon requires the STAR Portfolio to deposit, with its custodian for
the benefit of a futures commission merchant, or directly with the futures
commission merchant, as security for its obligations an amount of cash or other
specified assets (initial margin) which initially is typically 1% to 10% of the
face amount of the contract (but may be higher in some circumstances).
Additional cash or assets (variation margin) may be required to be deposited
directly with the futures commission merchant thereafter on a daily basis as the
value of the contract fluctuates. The purchase of an option on financial futures
involves payment of a premium for the option without any further obligation on
the part of the STAR Portfolio. If the STAR Portfolio exercises an option on a
futures contract it will be obligated to post initial margin (and potential
subsequent variation margin) for the resulting futures position just as it would
for any position. Futures contracts and options thereon are generally settled by
entering into an offsetting transaction but there can be no assurance that the
position can be offset prior to settlement at an advantageous price, nor that
delivery will occur. The segregation requirements with respect to futures
contracts and options thereon are described below.

Combined Transactions. The STAR Portfolio may enter into multiple transactions,
including multiple options transactions, multiple futures transactions and
multiple interest rate transactions, structured notes and any combination of
futures, options and interest rate transactions ("component transactions")
instead of a single Strategic Transaction, as part of a single or combined
strategy when, in the opinion of the STAR Portfolio's Adviser, it is in the best
interests of the STAR Portfolio to do so. A combined transaction will usually
contain elements of risk that are present in each of its component transactions.
Although combined transactions are normally entered into by the STAR Portfolio
based on its Adviser's judgment that the combined strategies will reduce risk or
otherwise more effectively achieve the desired portfolio management goal, it is
possible that the combination will instead increase such risks or hinder
achievement of the portfolio management objective.


                                       13

Swaps, Caps, Floors and Collars. Among the Strategic Transactions into which the
STAR Portfolio may enter are interest rate, index and total return swaps and the
purchase or sale of related caps, floors and collars. The STAR Portfolio expects
to enter into these transactions primarily for hedging purposes, including, but
not limited to, preserving a return or spread on a particular investment or
portion of its portfolio, as a duration management technique or protecting
against an increase in the price of securities that the STAR Portfolio
anticipates purchasing at a later date. Swaps, caps, floors and collars may also
be used to enhance potential gain in circumstances where hedging is not involved
although, as described above, the STAR Portfolio will attempt to limit its net
loss exposure resulting from swaps, caps, floors and collars and other Strategic
Transactions entered into for such purposes to not more than 1% of its net
assets at any one time. The STAR Portfolio will not sell interest rate caps,
floors or collars where it does not own securities or other instruments
providing the income stream the STAR Portfolio may be obligated to pay. Interest
rate swaps involve the exchange by the STAR Portfolio with another party of
their respective commitments to pay or receive interest, e.g., an exchange of
floating rate payments for fixed rate payments with respect to a notional amount
of principal. An index swap is an agreement to swap cash flows on a notional
amount based on changes in the values of the reference indices. The purchase of
a cap entitles the purchaser to receive payments on a notional principal amount
from the party selling such cap to the extent that a specified index exceeds a
predetermined interest rate or amount. The purchase of a floor entitles the
purchaser to receive payments on a notional principal amount from the party
selling such floor to the extent that a specified index falls below a
predetermined interest rate or amount. A collar is a combination of a cap and a
floor that preserves a certain rate of return within a predetermined range of
interest rates or values.

The STAR Portfolio will usually enter into swaps on a net basis, i.e., the two
payment streams are netted out in a cash settlement on the payment date or dates
specified in the instrument, with the STAR Portfolio receiving or paying, as the
case may be, only the net amount of the two payments. The STAR Portfolio will
not enter into any swap, cap, floor or collar transaction unless, at the time of
entering into such transaction, the unsecured long-term debt of the
Counterparty, combined with any credit enhancements, is rated at least A by
Standard & Poor's or Moody's or has an equivalent rating from an NRSRO or the
Counterparty issues debt that is determined to be of equivalent credit quality
by the STAR Portfolio's Adviser. If there is a default by the Counterparty, the
STAR Portfolio may have contractual remedies pursuant to the agreements related
to the transaction. The swap market has grown substantially in recent years with
a large number of banks and investment banking firms acting both as principals
and as agents utilizing standardized swap documentation. As a result, the swap
market has become relatively liquid. Caps, floors and collars are more recent
innovations for which standardized documentation has not yet been fully
developed. Swaps, caps, floors and collars are considered illiquid for purposes
of the STAR Portfolio's policy regarding illiquid securities, unless it is
determined, based upon continuing review of the trading markets for the specific
security, that such security is liquid. The Trustees of the Standish Portfolio
Trust have adopted guidelines and delegated to the STAR Portfolio's Adviser the
daily function of determining and monitoring the liquidity of swaps, caps,
floors and collars. Such Trustees, however, retain oversight focusing on factors
such as valuation, liquidity and availability of information and they are
ultimately responsible for such determinations. The staff of the Securities and
Exchange Commission 


                                       14
<PAGE>


("SEC") currently takes the position that swaps, caps, floors and collars are
illiquid, and are subject to the STAR Portfolio's limitation on investing in
illiquid securities.

Eurodollar Contracts. The STAR Portfolio may make investments in Eurodollar
contracts. Eurodollar contracts are U.S. dollar-denominated futures contracts or
options thereon which are linked to the London Interbank Offered Rate ("LIBOR"),
although foreign currency-denominated instruments are available from time to
time. Eurodollar futures contracts enable purchasers to obtain a fixed rate for
the lending of funds and sellers to obtain a fixed rate for borrowings. The STAR
Portfolio might use Eurodollar futures contracts and options thereon to hedge
against changes in LIBOR, to which many interest rate swaps and fixed income
instruments are linked.

Use of Segregated Accounts. The STAR Portfolio will hold securities or other
instruments whose values are expected to offset its obligations under the
Strategic Transactions. The STAR Portfolio will cover Strategic Transactions as
required by interpretive positions of the staff of the SEC. The STAR Portfolio
will not enter into Strategic Transactions that expose the STAR Portfolio to an
obligation to another party unless it owns either (i) an offsetting position in
securities or other options, futures contracts or other instruments or (ii)
cash, receivables or liquid securities with a value sufficient to cover its
potential obligations. The STAR Portfolio may have to comply with any applicable
regulatory requirements for Strategic Transactions, and if required, will set
aside cash and other assets in a segregated account with its custodian bank (or
marked as segregated on the STAR Portfolio's books) in the amount prescribed. In
that case, the STAR Portfolio's custodian would maintain the value of such
segregated account equal to the prescribed amount by adding or removing
additional cash or other assets to account for fluctuations in the value of the
account and the STAR Portfolio's obligations on the underlying Strategic
Transactions. Assets held in a segregated account would not be sold while the
Strategic Transaction is outstanding, unless they are replaced with similar
assets. As a result, there is a possibility that segregation of a large
percentage of the STAR Portfolio's assets could impede portfolio management or
the Portfolio's ability to meet redemption requests or other current
obligations.

   
"When-Issued" and "Delayed Delivery" Securities. Each Portfolio may invest up
to 10% of its net assets in securities purchased on a "when-issued" or "delayed
delivery" basis. Delivery and payment for securities purchased on a when-issued
or delayed delivery basis will normally take place 15 to 45 days after the date
of the transaction. The payment obligation and interest rate on the securities
are fixed at the time that a Portfolio enters into the commitment, but interest
will not accrue to a Portfolio until delivery of and payment for the securities.
Although each such Portfolio will only make commitments to purchase
"when-issued" and "delayed delivery" securities with the intention of actually
acquiring the securities, each such Portfolio may sell the securities before the
settlement date if deemed advisable by their investment adviser or sub-adviser.
A Portfolio may also, with respect to up to 25% of its net assets, enter into
contracts to purchase securities for a fixed price at a future date beyond
customary settlement time.
    

Unless the Portfolios have entered into an offsetting agreement to sell the
securities purchased on a "when-issued" or "forward commitment" basis, cash or
liquid obligations with a market value 


                                       15
<PAGE>


equal to the amount of a Portfolio's commitment will be segregated with a
Portfolio's custodian bank. If the market value of these securities declines,
additional cash or securities will be segregated daily so that the aggregate
market value of the segregated securities equals the amount of a Portfolio's
commitment.

Securities purchased on a "when-issued" and "delayed delivery" basis may have a
market value on delivery which is less than the amount paid by a Portfolio.
Changes in market value may be based upon the public's perception of the
creditworthiness of the issuer or changes in the level of interest rates.
Generally, the value of "when-issued", "delayed delivery" and "forward
commitment" securities will fluctuate inversely to changes in interest rates,
i.e., they will appreciate in value when interest rates fall and will decline in
value when interest rates rise.

Portfolio Turnover. It is not the policy of the STAR Portfolio to purchase or
sell securities for trading purposes. However, the STAR Portfolio does not place
any restrictions on portfolio turnover and may sell any portfolio security
without regard to the period of time it has been held. The STAR Portfolio may
therefore generally change its portfolio investments at any time in accordance
with its Adviser's appraisal of factors affecting any particular issuer or
market, or relevant economic conditions. The portfolio turnover rate for the
STAR Portfolio is generally not expected to exceed 150% on an annual basis. A
rate of turnover of 100% would occur if the value of the lesser of purchases and
sales of portfolio securities for a particular year equaled the average monthly
value of portfolio securities owned during the year (excluding short-term
securities). A high rate of portfolio turnover (100% or more) involves a
correspondingly greater amount of brokerage commissions and other costs which
must be borne directly by the STAR Portfolio and thus indirectly by its
interestholders. It may also result in the realization of larger amounts of net
short-term capital gains, distributions of which by an interestholder in the
STAR Portfolio that is a regulated investment company are taxable as ordinary
income.

                             Investment Restrictions

The Funds and the Portfolios have adopted the following fundamental policies.
Each of the Fund's and Portfolio's fundamental policies cannot be changed unless
the change is approved by a "vote of the outstanding voting securities" of a
Fund or a Portfolio, as the case may be, which phrase as used herein means the
lesser of (i) 67% or more of the voting securities of a Fund or Portfolio
present at a meeting, if the holders of more than 50% of the outstanding voting
securities of a Fund or Portfolio are present or represented by proxy, or (ii)
more than 50% of the outstanding voting securities of a Fund or Portfolio.

   
As a matter of fundamental policy, the Cash Portfolio (Fund), the Treasury Plus
Portfolio (Fund) and the Treasury Portfolio (Fund) may not:

       (1) purchase any securities that would cause more than 25% of the total
       assets of the Portfolio at the time of such purchase to be invested in
       securities of one or more issuers conducting their principal business
       activities in the same industry, provided that there is no limitation
       with respect to U.S. Government Securities or (for the Cash Portfolio
       (Fund) and 


                                       16
<PAGE>


       the Treasury Plus Portfolio (Fund)) bank obligations or repurchase
       agreements collateralized by any of such obligations as applicable;
    

       (2) borrow money, except as a temporary measure for extraordinary or
       emergency purposes or to facilitate redemptions, provided that borrowing
       does not exceed an amount equal to 33 1/3% of the current value of the
       Portfolio's assets taken at market value, less liabilities, other than
       borrowings;

       (3) purchase securities on margin (except for delayed delivery or
       when-issued transactions or such short-term credits as are necessary for
       the clearance of transactions);

       (4) make loans to any person or firm; provided, however, that the making
       of a loan shall not include entering into repurchase agreements, and
       provided further that a Portfolio may lend its portfolio securities to
       broker-dealers or other institutional investors if the aggregate value of
       all securities loaned does not exceed 33 1/3% of the value of a
       Portfolio's total assets;

       (5) engage in the business of underwriting the securities issued by
       others, except that a Portfolio will not be deemed to be engaging in the
       business of underwriting with respect to the purchase or sale of
       securities subject to legal or contractual restrictions on disposition;

       (6) issue senior securities, except as permitted by its investment
       objective, policies and restrictions, and except as permitted by the 1940
       Act; and

       (7) purchase or sell real estate, commodities, or commodity contracts
       unless acquired as a result of ownership of securities, and provided
       further that a Portfolio may invest in securities backed by real estate
       and in financial futures contracts and options thereon.

   
       If any percentage restriction described above for the Cash Portfolio
       (Fund), Treasury Plus Portfolio (Fund) or Treasury Portfolio (Fund) is
       adhered to at the time of investment, a subsequent increase or decrease
       in the percentage resulting from a change in the net assets of the
       Portfolios (Fund) will not constitute a violation of the restriction. The
       above restrictions also apply to each Fund, with the exception that a
       Fund may invest all of its investable assets without limitation in its
       respective Portfolio.
    

       As a matter of fundamental policy, the STAR Portfolio (Fund) may not:

       (1) Issue senior securities. For purposes of this restriction, borrowing
       money, making loans, the issuance of shares of beneficial interest in
       multiple classes or series, the deferral of Trustees' fees, the purchase
       or sale of options, futures contracts, forward commitments and repurchase
       agreements entered into in accordance with the Portfolio's (Fund's)
       investment policies, are not deemed to be senior securities.

       (2) Borrow money, except (i) in amounts not to exceed 33 1/3% of the
       value of the Portfolio's (Fund's) total assets (including the amount
       borrowed) taken at market value from 


                                       17
<PAGE>


       banks or through reverse repurchase agreements or forward roll
       transactions, (ii) up to an additional 5% of its total assets for
       temporary purposes, (iii) in connection with short-term credits as may be
       necessary for the clearance of purchases and sales of portfolio
       securities and (iv) the Portfolio (Fund) may purchase securities on
       margin to the extent permitted by applicable law. For purposes of this
       investment restriction, investments in short sales, roll transactions,
       futures contracts, options on futures contracts, securities or indices
       and forward commitments, entered into in accordance with the Portfolio's
       (Fund's) investment policies, shall not constitute borrowing.

       (3) Underwrite the securities of other issuers, except to the extent
       that, in connection with the disposition of portfolio securities, the
       Portfolio (Fund) may be deemed to be an underwriter under the Securities
       Act of 1933.

       (4) Purchase or sell real estate except that the Portfolio (Fund) may (i)
       acquire or lease office space for its own use, (ii)invest in securities
       of issuers that invest in real estate or interests therein, (iii) invest
       in securities that are secured by real estate or interests therein, (iv)
       purchase and sell mortgage-related securities and (v) hold and sell real
       estate acquired by the Portfolio (Fund) as a result of the ownership of
       securities.

       (5) Purchase or sell commodities or commodity contracts, except the
       Portfolio (Fund) may purchase and sell options on securities, securities
       indices and currency, futures contracts on securities, securities indices
       and currency and options on such futures, forward foreign currency
       exchange contracts, forward commitments, securities index put or call
       warrants and repurchase agreements entered into in accordance with the
       Portfolio's (Fund's) investment policies.

       (6) Make loans, except that the Portfolio (Fund) (1) may lend portfolio
       securities in accordance with the Portfolio's (Fund's) investment
       policies up to 33 1/3% of the Portfolio's (Fund's) total assets taken at
       market value, (2) enter into repurchase agreements, and (3) purchase all
       or a portion of an issue of debt securities, bank loan participation
       interests, bank certificates of deposit, bankers' acceptances, debentures
       or other securities, whether or not the purchase is made upon the
       original issuance of the securities.

       (7) With respect to 75% of its total assets, purchase securities of an
       issuer (other than the U.S. Government, its agencies, instrumentalities
       or authorities or repurchase agreements collateralized by U.S. Government
       securities and other investment companies), if: (a) such purchase would
       cause more than 5% of the Portfolio's (Fund's) total assets taken at
       market value to be invested in the securities of such issuer; or (b) such
       purchase would at the time result in more than 10% of the outstanding
       voting securities of such issuer being held by the Portfolio (Fund).

       (8) Invest more than 25% of its total assets in the securities of one or
       more issuers conducting their principal business activities in the same
       industry (excluding the U.S. Government or its agencies or
       instrumentalities).

The following restrictions are not fundamental policies and may be changed by
the Trustees of the Standish Portfolio Trust without investor approval in
accordance with applicable laws, regulations or regulatory policy.
The STAR Portfolio (Fund) may not:

a. Purchase securities on margin (except that the Portfolio (Fund) may obtain
such short-term credits as may be necessary for the clearance of purchases and
sales of securities).

b. Invest in the securities of an issuer for the purpose of exercising control
or management, but it may do so where it is deemed advisable to protect or
enhance the value of an existing investment.

c. Purchase the securities of any other investment company except to the extent
permitted by the 1940 Act.

d. Invest more than 15% of its net assets in securities which are illiquid.

e. Purchase additional securities if the Portfolio's (Fund's) borrowings exceed
5% of its net assets.

It is expected that not more than 5% of the STAR Portfolio's net assets will be
at risk as a result of investment in inverse floating rate securities.

   
Notwithstanding any fundamental or non-fundamental policy, the STAR Series may
invest all of its assets (other than assets which are not "investment
securities" (as defined in the 1940 Act) or are excepted by the SEC) in an
open-end investment company with substantially the same investment objective as
the STAR Series.
    

For the purposes of STAR Portfolio's (Fund's) fundamental restriction 8, state
and municipal governments and their agencies, authorities and instrumentalities
are not deemed to be industries; telephone companies are considered to be a
separate industry from water, gas or electric utilities; 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. Fundamental restriction 8 does not apply to
investments in municipal securities which have been prefunded by the use of
obligations of the U.S. Government or any of its agencies or instrumentalities.
For purposes of fundamental restriction 8, the industry classification of an
asset-backed security is determined by its underlying assets. For example,
certificates for automobile receivables and certificates for amortizing
revolving debts constitute two different industries.

If any percentage restriction described above for the STAR Portfolio (Fund) is
adhered to at the time of investment, a subsequent increase or decrease in the
percentage resulting from a change in the value of the Portfolio's (Fund's)
assets will not constitute a violation of the restriction.

               Control Persons and Principal Holders of Securities

   
As of October 1, 1998, the Standish Short-Term Asset Reserve Fund owned
approximately 100% of the outstanding interests of the STAR Portfolio and,
therefore, was deemed to control the STAR Portfolio. As of October 1, 1998, the
Merrimac Cash Fund beneficially owned approximately 77.18% and the Merrimac Cash
Series beneficially owned approximately 21.81% of the outstanding interests of
the Cash Portfolio. As of October 1, 1998, the Merrimac Treasury Series owned
approximately 100% of the outstanding interests of the Treasury Portfolio and,
therefore, was deemed to control the Treasury Portfolio. As controlling persons,
Standish Short-Term Asset Reserve Fund and the Merrimac Treasury Series each may
be able to take actions regarding their corresponding Portfolio without the
consent or approval of other interest holders.

                          Investment Advisory Services

Cash Portfolio, Treasury Plus Portfolio and Treasury Portfolio. The Cash
Portfolio, the Treasury Plus Portfolio and the Treasury Portfolio each retain
Investors Bank & Trust Company ("Investors Bank" or the "Adviser") as their
investment adviser. The Investment Adviser Agreement (the "Adviser Agreement")
between Investors Bank and each of the Cash Portfolio, the Treasury Plus
Portfolio and the Treasury Portfolio provides that Investors Bank will manage
the operations of the Cash Portfolio, the Treasury Plus Portfolio and the
Treasury Portfolio, subject to the policies established by the Board of Trustees
of the Trust. Investors Bank also provides office space, facilities, equipment
and personnel necessary to supervise the Cash, Treasury Plus and the Treasury
Portfolios' operations and pays the compensation of each such Portfolio's
officers, employees and directors affiliated with Investors Bank. For a
description of the rate of compensation that the Cash Portfolio, the Treasury
Plus Portfolio and the Treasury Portfolio pay Investors Bank under the Adviser
Agreement, see the current Prospectus. Investors Bank's business address is 200
Clarendon Street, Boston, Massachusetts 02116.

The Board of Trustees of the Portfolio Trust (including a majority of the
Trustees who are not "interested" persons of the Portfolio Trust) last approved
the Adviser Agreement for the Cash Portfolio on October 26, 1998, the Treasury
Plus Portfolio on October 26, 1998 and the Treasury Portfolio on February 6,
1997. The Adviser Agreements each provide that they will continue initially for
two years from their date of execution, and from year to year thereafter as long
as they are approved at least annually (a) by vote of a majority of such
Portfolio's outstanding voting securities or by the Portfolio Trust's Board of
Trustees and (b) by the vote of a majority of the Portfolio Trust's Trustees who
are not parties to the Adviser Agreement or "interested persons" of any such
party. Each Adviser Agreement may be terminated on 60 days' written notice by
either party and will terminate automatically if assigned. Each Adviser
Agreement provides in substance that the Adviser shall not be liable for any
action or failure to act in accordance with its duties thereunder in the absence
of willful misfeasance, bad faith or gross negligence on the part of the Adviser
or of reckless disregard of its obligations thereunder.

Pursuant to Investment Sub-Adviser Agreements (the "M&I Sub-Adviser
Agreements"), Investors Bank has retained M&I Investment Management Corp.
("M&I") as sub-adviser to the Treasury Plus Portfolio and the Treasury
Portfolio. M&I is compensated by Investors Bank at no additional cost to the
Treasury Plus Portfolio and the Treasury Portfolio. Subject to the supervision
of Investors Bank and of the Portfolio Trust's Board of Trustees, M&I furnishes
to the Treasury Plus Portfolio and the Treasury Portfolio investment research,
advice and supervision and determines what securities will be purchased, held or
sold by the Treasury Plus Portfolio and the Treasury Portfolio. For a
description of the rate of compensation that Investors Bank pays M&I under the
M&I Sub-Adviser Agreements, see the Prospectus. M&I's business address is 1000
North Water Street, Milwaukee, Wisconsin 53202.

The Cash, Treasury Plus and Treasury Portfolios bear the expenses of their
operations other than those incurred by AAM or M&I, respectively. Among the
other expenses, the Portfolios pay share pricing and shareholder servicing fees
and expenses; custodian fees and expenses; legal and auditing fees and expenses;
expenses of shareholder reports; registration and reporting fees and expenses;
and the Portfolio Trust's Trustees' fees and expenses.
    

STAR Portfolio. The STAR Portfolio and Standish, Ayer & Wood, Inc. ("Standish")
have entered into an investment advisory agreement (the "Standish Advisory
Agreement") under which Standish serves as investment adviser. Prior to the
close of business on January 1, 1998, Standish managed directly the assets of
the Standish STAR Fund pursuant to an investment advisory agreement. This
agreement was terminated by the Standish STAR Fund on such date subsequent to
the approval by Standish STAR Fund's shareholders on December 17, 1997 to
implement certain changes in the Standish STAR Fund's investment restrictions
which would enable the Standish STAR Fund to invest all of its investable assets
in the newly-created STAR Portfolio. Each of the STAR Fund and the Standish STAR
Fund invests all of its investable assets in the STAR Portfolio as a separate
management investment company.

The following, constituting all of the Directors and all of the shareholders of
Standish, are Standish's controlling persons: Caleb F. Aldrich, Nicholas S.
Battelle, David H. Cameron, Karen K. Chandor, D. Barr Clayson, W. Charles Cook,
Joseph M. Corrado, Richard C. Doll, Dolores S.

For a description of the rate of compensation that the STAR Fund pays Standish
and the services provided by Standish under the Standish Advisory Agreement, see
the Prospectus. Standish's business address is One Financial Center, Boston,
Massachusetts 02111.

Unless terminated as provided below, the Standish Advisory Agreement continues
in full force and effect until December 31, 1999 and from year to year
thereafter, but only for so long as each such continuance is approved annually
(i) by the Trustees of the Standish Portfolio Trust or by the "vote of a
majority of the outstanding voting securities" of the STAR Portfolio and, in
either event (ii) by vote of a majority of the Trustees of the Portfolio Trust
who are not parties to the Standish Advisory Agreement or "interested persons"
(as defined in the 1940 Act) of any such party, cast in person at a meeting
called for the purpose of voting on such approval. The Standish Advisory
Agreement may be terminated at any time without the payment of any penalty by
vote of the Trustees of the Standish Portfolio Trust or by the "vote of a
majority of the outstanding voting securities" of the STAR Portfolio or by
Standish, on sixty days' written notice to the other party. The Standish
Advisory Agreement terminates in the event of its assignment as defined in the
1940 Act.

In an attempt to avoid any potential conflict with portfolio transactions for
the STAR Fund and the STAR Portfolio, Standish and the Standish Portfolio Trust
have each adopted restrictions on personal securities trading by personnel of
Standish and its affiliates. These restrictions include: pre-clearance of all
personal securities transactions and a prohibition of purchasing initial public
offerings of securities. These restrictions are a continuation of the basic
principle that the interests of the STAR Fund and its shareholders, and the STAR
Portfolio and its investors, come before those of Standish and its employees.

The STAR Portfolio bears expenses of its operations other than those incurred by
Standish. Among the other expenses, the Portfolio pays share pricing and
expenses; custodian fees and expenses; legal and auditing fees and expenses;
expenses of prospectuses, statements of additional information and shareholder
reports; registration and reporting fees and expenses; and Standish Portfolio
Trust's Trustees' fees and expenses.

                                   Distributor

The Premium, Institutional and Investment Class shares of the Funds are
continuously distributed by the Distributor pursuant to a Distribution Agreement
with the Trust dated June 1, 1998. The Distributor makes itself available to
receive purchase orders for the Funds' shares. Pursuant to the Distribution
Agreement, the Distributor has agreed to use its best efforts to obtain orders
for the continuous offering of the Funds' shares. The Distributor receives no
commissions or other compensation from the Funds for its services, but receives
compensation from Investors 


                                       26
<PAGE>


Bank for services it performs in acting as the Funds' Distributor.

The Distribution Agreement shall continue in effect with respect to the Funds
until two years after its execution and for successive periods of one year
thereafter only if it is approved at least annually thereafter (i) by a vote of
the holders of a majority of the Trust's outstanding shares or by the Trustees
of the Trust or (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. The Distribution Agreement will terminate automatically
if assigned by either party thereto and is terminable at any time without
penalty on not more than 60 days' written notice to the other party. The offices
of the Distributor are located at 60 State Street, Suite 1300, Boston,
Massachusetts 02109.

The Board of Trustees of the Trust has adopted a Plan of Distribution (the
"Distribution Plan") under Rule 12b-1 of the 1940 Act with respect to the
Investment Class of shares of each Fund after having concluded that there is a
reasonable likelihood that the Distribution Plan will benefit the Funds and
their shareholders. The Distribution Plan provides that the Distribution Agent
(defined therein) shall receive a fee from each Fund at an annual rate not to
exceed 0.25% of the average daily net assets of such Fund attributable to
shareholders who are clients of the Distribution Agent, plus reimbursement of
direct out of pocket expenditures incurred in connection with the offer or sale
or shares, including expenses relating to the preparation, printing and
distribution of sales literature and reports.

The Distribution Plan will initially be effective for one year from its
effective date. Thereafter, the Distribution Plan shall continue in effect only
if such continuance is specifically approved at least annually by a vote of both
a majority of the Board of Trustees of the Trust and a majority of the Trustees
of the Trust who are not "interested persons" of the Trust (the "Disinterested
Trustees.") The Distribution Plan may be terminated with respect to a Fund at
any time by a vote of a majority of the Disinterested Trustees, or by a vote of
a majority of the outstanding voting shares of such Fund.

The Board of Trustees of the Trust have also adopted a Shareholder Servicing
Plan (the "Servicing Plan") with respect to the Institutional Class and
Investment Class shares of each Fund after having concluded that there is a
reasonable likelihood that the Servicing Plan will benefit the Funds and their
shareholders. The Servicing Plan provides that the Shareholder Servicing Agent
shall receive a fee from each Fund at an annual rate not to exceed 0.25% of the
average daily net assets of such Fund.

The Servicing Plan will initially be effective for one year from its effective
date. Thereafter, the Servicing Plan continues in effect if such continuance is
specifically approved at least annually by a vote of both a majority of the
Board of Trustees of the Trust and a majority of the Qualified Trustees. The
Servicing Plan requires that at least quarterly, the Treasurer of the Trust
provide to the Trustees of the Trust and that the Trustees review a written
report of the amounts expended pursuant to the Servicing Plan and the purposes
for which such expenditures were made. The Servicing Plan further provides that
the selection and nomination of the Trust's Qualified Trustees is committed to
the discretion of the Trust's disinterested Trustees then in office. The

Servicing Plan may be terminated at any time by a vote of a majority of the
Qualified Trustees, or by a vote of a majority of the outstanding voting shares
of such Fund. The Plan may not be amended to increase materially the amount of a
Fund's permitted expenses thereunder without the approval of a majority of the
outstanding voting securities of the affected Class of such Fund and may not be
materially amended in any case without a vote of the majority of both the
Trust's Trustees and the Trust's Qualified Trustees.

                              Redemption of Shares

   
Detailed information on redemption of shares is included in the Prospectus. The
Trust may suspend the right to redeem Fund shares or postpone the date of
payment upon redemption for more than seven days (i) for any period during which
the New York Stock Exchange ("NYSE") and the Federal Reserve Bank ("Fed") are
closed (other than customary weekend or holiday closings) or trading on the
exchange is restricted; (ii) for any period during which an emergency exists as
a result of which disposal by the Fund of securities owned by it or
determination by the Fund of the value of its net assets is not reasonably
practicable; or (iii) for such other periods as the SEC may permit for the
protection of shareholders of the Fund.
    

The Trust intends to pay redemption proceeds in cash for all Fund shares
redeemed but, under certain conditions, the Trust, with respect to the STAR
Fund, may make payment wholly or partly in portfolio securities, in conformity
with a rule of the SEC. Portfolio securities paid upon redemption of Fund shares
will be valued at their then current market value. An investor may incur
brokerage costs in converting portfolio securities received upon redemption to
cash. The Portfolios have advised the Trust that the Portfolios will not redeem
in-kind except in circumstances in which a Fund is permitted to redeem in-kind
or except in the event a Fund completely withdraws its interest from a
Portfolio.

                             Portfolio Transactions

   
Cash Portfolio, Treasury Plus Portfolio and Treasury Portfolio. Purchases and
sales of securities for the Cash, Treasury Plus and Treasury Portfolios usually
are principal transactions. Securities are normally purchased directly from the
issuer or from an underwriter or market maker for the securities. There usually
are no brokerage commissions paid for such purchases. The Cash Portfolio,
Treasury Plus Portfolio and the Treasury Portfolio do not anticipate paying
brokerage commissions. Any transaction for which the Cash Portfolio, Treasury
Plus Portfolio or the Treasury Portfolio pays a brokerage commission will be
effected at the best price and execution available. Purchases from underwriters
of securities include a commission or concession paid by the issuer to the
underwriter and purchases from dealers serving as market makers include the
spread between the bid and asked price.

Allocations of transactions, including their frequency, to various dealers is
determined by the respective Sub-Advisers in their best judgment and in a manner
deemed to be in the best interest of each of the Cash Series, Treasury Plus
Series and the Treasury Series and the other investors in the Cash Portfolio,
Treasury Plus Portfolio or the Treasury Portfolio rather than by any 


                                       28
<PAGE>


formula. The primary consideration is prompt execution of orders in an effective
manner at the most favorable price.

Investment decisions for the Cash Portfolio, Treasury Plus Portfolio and the
Treasury Portfolio will be made independently from those for any other account
or investment company that is or may in the future become managed by the
Sub-Advisers. If, however, the Cash Portfolio, Treasury Plus Portfolio or the
Treasury Portfolio and other accounts managed by its Sub-Adviser are
contemporaneously engaged in the purchase or sale of the same security, the
transactions may be averaged as to price and allocated equitably to each
account. In some cases, this policy might adversely affect the price paid or
received by the Cash Portfolio, Treasury Plus Portfolio or the Treasury
Portfolio or the size of the position obtainable for the Cash Portfolio,
Treasury Plus Portfolio or the Treasury Portfolio. In addition, when purchases
or sales of the same security for the Cash Portfolio, Treasury Plus Portfolio or
the Treasury Portfolio and for other accounts managed by their Sub-Adviser occur
contemporaneously, the purchase or sale orders may be aggregated in order to
obtain any price advantages available to large denomination purchases or sales.
    

STAR Portfolio. Standish is responsible for placing the STAR Portfolio's
portfolio transactions and will do so in a manner deemed fair and reasonable to
the STAR Portfolio and not according to any formula. The primary consideration
in all portfolio transactions will be prompt execution of orders in an efficient
manner at the most favorable price. In selecting broker-dealers and in
negotiating commissions, Standish will consider the firm's reliability, the
quality of its execution services on a continuing basis and its financial
condition. If Standish determines in good faith that the amount of commissions
charged by a broker is reasonable in relation to the value of the brokerage and
research services provided by such broker, the STAR Portfolio may pay
commissions to such broker in an amount greater than the amount another firm may
charge. Research services may include (i) furnishing advice as to the value of
securities, the advisability of investing in, purchasing or selling securities,
and the availability of securities or purchasers or sellers of securities, (ii)
furnishing seminars, information, analyses and reports concerning issuers,
industries, securities, trading markets and methods, legislative developments,
changes in accounting practices, economic factors and trends, portfolio
strategy, access to research analysts, corporate management personnel, industry
experts and economists, comparative performance evaluation and technical
measurement services and quotation services, and products and other services
(such as third party publications, reports and analysis, and computer and
electronic access, equipment, software, information and accessories that
deliver, process or otherwise utilize information, including the research
described above) that assist Standish in carrying out its responsibilities and
(iii) effecting securities transactions and performing functions incidental
thereto (such as clearance and settlement). Research services furnished by firms
through which the STAR Portfolio effects its securities transactions may be used
by Standish in servicing other accounts; not all of these services may be used
by Standish in connection with the STAR Portfolio. The investment advisory fee
paid by the STAR Portfolio under the Standish Advisory Agreement will not be
reduced as a result of Standish's receipt of research services.

Standish also places portfolio transactions for other advisory accounts.
Standish will seek to allocate portfolio transactions equitably whenever
concurrent decisions are made to purchase or 


                                       29
<PAGE>


sell securities for the STAR Portfolio and another advisory account. In some
cases, this procedure could have an adverse effect on the price or the amount of
securities available to the STAR Portfolio. In making such allocations, the main
factors considered by Standish will be the respective investment objectives, the
relative size of portfolio holdings of the same or comparable securities, the
availability of cash for investment, the size of investment commitments
generally held, and opinions of the persons responsible for recommending the
investment. To the extent permitted by law, securities to be sold or purchased
for STAR Portfolio may be aggregated with those to be sold or purchased for
other investment clients of Standish and Standish's personnel in order to obtain
best execution.

Because most of the STAR Portfolio's securities transactions will be effected on
a principal basis involving a "spread" or "dealer mark-up," the Portfolio does
not expect to pay any brokerage commissions.

                          Net Asset Value Determination
   
Each Fund's NAV is calculated each day on which both the NYSE and the New York
Federal Reserve Bank are open (a "Business Day"). Currently, the NYSE is not
open on weekends, New Year's Day, Martin Luther King Day, Presidents' Day, Good
Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and
Christmas Day. The New York Federal Reserve Bank is not open on weekends, the
holidays listed above and on Columbus Day and Veterans' Day. The NAV of the Cash
Series and the Treasury Plus Series' shares is determined once each Business Day
as of 5:00 p.m. (ET). The NAV of the Treasury Series' shares is determined once
each Business Day as of 2:00 p.m. (ET). The NAV of the STAR Series' shares is
determined once each Business Day as of the close of trading on the NYSE
(normally 4:00 p.m. (ET).

The NAV of each Fund is computed by dividing the value of all securities and
other assets of each Fund (substantially all of which will be represented by
such Fund's interest in its corresponding Portfolio) less all liabilities, by
the number of Fund shares outstanding, and adjusting to the nearest cent per
share. Expenses and fees of each Fund are accrued daily and taken into account
for the purpose of determining NAV.

The value of each Portfolio's net assets (i.e., the value of its securities and
other assets less its liabilities, including expenses payable or accrued) is
determined at the same time and on the same days as the NAV per share of its
corresponding Fund is determined. Each investor in a Portfolio may add to or
reduce its investment in such Portfolio on each Business Day. As of 4:00 p.m.
ET, for the STAR Portfolio on each Business Day, the value of each investor's
interest in the STAR Portfolio will be determined by multiplying the NAV of such
Portfolio by the percentage representing that investor's share of the aggregate
beneficial interests in the STAR Portfolio. Any additions or reductions which
are to be effected on that day will then be effected. The investor's percentage
of the aggregate beneficial interests in the STAR Portfolio will then be
recomputed as the percentage equal to the fraction (i) the numerator of which is
the value of such investor's investment in the STAR Portfolio as of 4:00 p.m.
(ET) for the STAR Portfolio on such 


                                       30
<PAGE>


day plus or minus, as the case may be, the amount of net additions to or
reductions in the investor's investment in the STAR Portfolio effected on such
day, and (ii) the denominator of which is the aggregate NAV of the Portfolio as
of 4:00 p.m. (ET) (on each day the NYSE is open for trading, for the STAR
Portfolio) on such day plus or minus, as the case may be, the amount of the net
additions to or reductions in the aggregate investments in the STAR Portfolio by
all investors in the STAR Portfolio. The percentage so determined will then be
applied to determine the value of the investor's interest in the STAR Portfolio
as of 4:00 p.m. (ET), for the STAR Portfolio on the following Business Day.

The following is a description of the procedures used by each Portfolio in
valuing its assets.

Cash Portfolio, Treasury Plus Portfolio and Treasury Portfolio. The investment
securities in the Cash Portfolio, the Treasury Plus Portfolio and the Treasury
Portfolio are valued based upon the amortized cost method which involves valuing
a security at its cost and thereafter assuming a constant amortization to
maturity of any discount or premium. Although the amortized cost method provides
consistency in valuation, it may result in periods during which the stated value
of a security is higher or lower than the price the Cash Portfolio, Treasury
Plus Portfolio or Treasury Portfolio would receive if the security were sold.
This method of valuation is used in order to stabilize the NAV of shares of the
Cash Series, the Treasury Plus Series or the Treasury Series at $1.00; however,
there can be no assurance that the Cash Series, the Treasury Plus Series or the
Treasury Series' NAV will always remain at $1.00 per share.
    

STAR Portfolio. Securities that are fixed income securities (other than money
market instruments) for which accurate market prices are readily available are
valued at their current market value on the basis of quotations, which may be
furnished by a pricing service or provided by dealers in such securities.
Securities not listed on an exchange or national securities market, certain
mortgage-backed and asset-backed securities and securities for which there were
no reported transactions are valued at the last quoted bid prices. Fixed income
securities for which accurate market prices are not readily available and all
other assets are valued at fair value as determined in good faith by Standish in
accordance with procedures approved by the Trustees of the Standish Portfolio
Trust, which may include the use of yield equivalents or matrix pricing.

Money market instruments with less than sixty days remaining to maturity when
acquired by the STAR Portfolio are valued on an amortized cost basis unless the
Trustees determine that amortized cost does not represent fair value. If the
STAR Portfolio acquires a money market instrument with more than sixty days
remaining to its maturity, it is valued at current market value until the
sixtieth day prior to maturity and will then be valued at amortized cost based
upon the value on such date unless the Trustees determine during such sixty-day
period that amortized cost does not represent fair value.

The Board of Trustees of the Standish Portfolio Trust has approved determining
the current market value of securities with one year or less remaining to
maturity on a spread basis which will be employed in conjunction with the
periodic use of market quotations. Under the spread process, Standish determines
in good faith the current market value of these portfolio securities by
comparing their quality, maturity and liquidity characteristics to those of
United States 


                                       31

Treasury bills.

                       Capital Stock and Other Securities

Each Fund is a diversified investment series of the Trust, an unincorporated
business trust organized under the laws of the State of Delaware pursuant to
Master Trust Agreement dated March 30, 1998 and registered as an open-end
management investment company under the 1940 Act. Under the Master Trust
Agreement, the Trustees of the Trust have authority to issue an unlimited number
of shares of beneficial interest, par value $0.001 per share, of each Fund. The
Master Trust Agreement authorizes the Board of Trustees to divide the shares
into any number of classes or series, each class or series having such
designations, powers, preferences, rights, qualifications, limitations and
restrictions, as shall be determined by the Board subject to the 1940 Act and
other applicable law. The shares of any such additional classes or series might
therefore differ from the shares of the present class and series of capital
stock and from each other as to preferences, conversion or other rights, voting
powers, restrictions, limitations as to dividends, qualifications or terms or
conditions of redemption, subject to applicable law, and might thus be superior
or inferior to the other classes or series in various characteristics.

The Trust generally is not required to hold meetings of its shareholders. Under
the Master Trust Agreement, however, shareholder meetings will be held in
connection with the following matters: (1) the election or removal of Trustees
if a meeting is called for such purpose; (2) the adoption of any investment
advisory contract; (3) any amendment of the Master Trust Agreement (other than
amendments changing the name of the Trust, supplying any omission, curing any
ambiguity or curing, correcting or supplementing any defective or inconsistent
provision thereof); and (4) such additional matters as may be required by law,
the Master Trust Agreement, the By-laws of the Trust or any registration of the
Trust with the SEC or any state, or as the Trust's Trustees may consider
necessary or desirable. The shareholders also would vote upon changes in
fundamental investment objectives, policies or restrictions.

Each Trustee serves until the next meeting of shareholders, if any, called for
the purpose of electing Trustees and until the election and qualification of his
successor or until such Trustee sooner dies, resigns or is removed by a vote of
two-thirds of the shares entitled to vote, or a majority of the Trustees. In
accordance with the 1940 Act (i) the Trust will hold a shareholder meeting for
the election of Trustees at such time as less than a majority of the Trustees
have been elected by shareholders, and (ii) if, as a result of a vacancy in the
Board of Trustees, less than two-thirds of the Trustees have been elected by the
shareholders, that vacancy will be filled only by a vote of the shareholders. A
shareholders' meeting shall be held for the purpose of voting upon the removal
of a Trustee upon the written request of the holders of not less than 10% of the
outstanding shares. Upon the written request of ten or more shareholders who
have been such for at least six months and who hold shares constituting at least
1% of the outstanding shares of a Fund stating that such shareholders wish to
communicate with the other shareholders for the purpose of obtaining the
signatures necessary to demand a meeting to consider removal of a Trustee, the
Trust has undertaken to disseminate appropriate materials at the expense of the
requesting shareholders.


                                       32
<PAGE>


The Master Trust Agreement provides that the presence at a shareholder meeting
in person or by proxy of at least 30% of the shares entitled to vote on a matter
shall constitute a quorum. Thus, a meeting of shareholders of the Trust could
take place even if less than a majority of the shareholders were represented on
its scheduled date. Shareholders would in such a case be permitted to take
action which does not require a larger vote than a majority of a quorum, such as
the election of Trustees and ratification of the selection of auditors. Some
matters requiring a larger vote under the Master Trust Agreement, such as
termination or reorganization of the Trust and certain amendments of the Master
Trust Agreement, would not be affected by this provision; nor would matters
which under the 1940 Act require the vote of a "majority of the outstanding
voting securities" as defined in the 1940 Act.

The Master Trust Agreement specifically authorizes the Board of Trustees to
terminate the Trust (or any series Fund thereof) by notice to the shareholders
without shareholder approval. The Board of Trustees may by amendment to the
Master Trust Agreement add to, delete, replace or otherwise modify any
provisions relating to any series or class, provided that before adopting any
such amendment without shareholder approval, the Board of Trustees determined
that it was consistent with the fair and equitable treatment of all shareholders
and, if shares have been issued, shareholder approval shall be required to adopt
any amendments which would adversely affect to a material degree the rights and
preferences of the shares of any series or class.

Each share of a Fund has equal voting rights with every other share of a Fund,
and all shares of a Fund vote as a single group except where a separate vote of
any class is required by the 1940 Act, the laws of the State of Delaware, the
Master Trust Agreement or the By-Laws, or as the Board may determine in its sole
discretion. Where a separate vote is required with respect to one or more
classes, then the shares of all other classes vote as a single class, provided
that, as to any matter which does not affect the interest of a particular class,
only the holders of shares of the one or more affected classes is entitled to
vote.

   
The Cash Portfolio, the Treasury Plus Portfolio and the Treasury Portfolio are
each a series or sub-trust of the Portfolio Trust, a common law trust organized
under New York law on October 30, 1996, registered as an open-end management
investment company under the 1940 Act. The STAR Portfolio is a series of the
Standish Portfolio Trust which, like the Trust and the Portfolio Trust, is an
open-end management investment company registered under the 1940 Act. The
Standish Portfolio Trust was organized as a master trust fund under the laws of
the State of New York on January 18, 1996.
    

Interests in each Portfolio have no preemptive or conversion rights, and are
fully paid and non-assessable, except as set forth in the Prospectus. The
Portfolio Trust and the Standish Portfolio Trust normally will not hold meetings
of holders of such interests except as required under the 1940 Act. The
Portfolio Trust and the Standish Portfolio Trust would be required to hold a
meeting of holders in the event that at any time less than a majority of its
Trustees holding office had been elected by holders. The Trustees of the
Portfolio Trust and the Standish Portfolio Trust continue to hold office until
their successors are elected and have qualified. Holders holding a specified
percentage of interests in a Portfolio may call a meeting of holders in such
Portfolio 


                                       33
<PAGE>


for the purpose of removing any Trustee. A Trustee of the Portfolio Trust or the
Standish Portfolio Trust may be removed upon a majority vote of the interests
held by holders in the Portfolio Trust or the Standish Portfolio Trust qualified
to vote in the election. The 1940 Act requires the Portfolio Trust and the
Standish Portfolio Trust to assist its holders in calling such a meeting. Upon
liquidation of a Portfolio, holders in a Portfolio would be entitled to share
pro rata in the net assets of the Portfolio available for distribution to
holders. Each holder in a Portfolio is entitled to a vote in proportion to its
percentage interest in such Portfolio.

                                    Taxation

Each Fund is treated as a separate entity for accounting and tax purposes. Each
Fund will elect (when it files its initial federal tax return) to be treated and
to qualify as a "regulated investment company" ("RIC") under Subchapter M of the
Code, and intends to continue to so qualify in the future. As such and by
complying with the applicable provisions of the Code regarding the sources of
its income, the timing of its distributions, and the diversification of its
assets, each Fund will not be subject to Federal income tax on its investment
company taxable income (i.e., all taxable income, after reduction by deductible
expenses, other than its "net capital gain," which is the excess, if any, of its
net long-term capital gain over its net short-term capital loss) and net capital
gain which are distributed to shareholders in accordance with the timing and
other requirements of the Code.

Each Portfolio is treated as a partnership for federal income tax purposes. As
such, a Portfolio is not subject to federal income taxation. Instead, a Fund
must take into account, in computing its federal income tax liability (if any),
its share of the Portfolio's income, gains, losses, deductions, credits and tax
preference items, without regard to whether it has received any cash
distributions from its corresponding Portfolio. Because a Fund invests its
assets in its corresponding Portfolio, the Portfolio normally must satisfy the
applicable source of income and diversification requirements in order for its
corresponding Fund to satisfy them. Each Portfolio will allocate at least
annually among its investors, each investor's distributive share of the
Portfolio's net investment income, net realized capital gains, and any other
items of income, gain, loss, deduction or credit. A Portfolio will make
allocations to its corresponding Fund in a manner intended to comply with the
Code and applicable regulations and will make moneys available for withdrawal at
appropriate times and in sufficient amounts to enable the Fund to satisfy the
tax distribution requirements that apply to the Fund and that must be satisfied
in order to avoid Federal income and/or excise tax on the Fund. For purposes of
applying the requirements of the Code regarding qualification as a RIC, each
Fund will be deemed (i) to own its proportionate share of each of the assets of
its corresponding Portfolio and (ii) to be entitled to the gross income of the
Portfolio attributable to such share.

Each Fund will be subject to a 4% non-deductible federal excise tax on certain
amounts not distributed (and not treated as having been distributed) on a timely
basis in accordance with annual minimum distribution requirements. Each Fund
intends under normal circumstances to seek to avoid liability for such tax by
satisfying such distribution requirements. Certain distributions made in order
to satisfy the Code's distribution requirements may be declared by a 


                                       34
<PAGE>


Fund during October, November or December but paid during the following January.
Such distributions will be taxable to taxable shareholders as if received on
December 31 of the year the distributions are declared, rather than the year in
which the distributions are received.

At the discretion of the officers of a Fund, each Fund will distribute net
realized capital gains. For federal income tax purposes, a Fund is permitted to
carry forward a net capital loss in any year to offset its own net capital
gains, if any, during the eight years following the year of the loss. To the
extent subsequent net capital gains are offset by such losses, they would not
result in federal income tax liability to a Fund and, as noted above, would not
be distributed as such to shareholders.

If the STAR Portfolio invests in zero coupon securities, certain increasing rate
or deferred interest securities or, in general, other securities with an
original issue discount (or with market discount if an election is in effect to
include market discount in income currently), the Portfolio must accrue income
on such investments prior to the receipt of the corresponding cash payments.
However, the STAR Series must distribute, at least annually, all or
substantially all of its net income, including its distributive share of such
income accrued by the STAR Portfolio, to shareholders to qualify as a regulated
investment company under the Code and avoid federal income and excise taxes.
Therefore, the STAR Portfolio may have to dispose of its portfolio securities
under disadvantageous circumstances to generate cash, or may have to leverage
itself by borrowing the cash, to enable the STAR Series to satisfy the
distribution requirements.

Limitations imposed by the Code on regulated investment companies may restrict
the STAR Portfolio's ability to enter into futures, options or currency forward
transactions.

Certain options or futures transactions undertaken by the STAR Portfolio may
cause the STAR Series to recognize gains or losses from marking to market even
though the STAR Portfolio's positions have not been sold or terminated and
affect the character as long-term or short-term and timing of some capital gains
and losses realized by the Portfolio and allocable to the Fund. Additionally,
the STAR Portfolio (and STAR Series) may be required to recognize gain if an
option, future, forward contract, short sale, swap or other strategic
transaction that is not subject to the mark to market rules is treated as a
"constructive sale" of an "appreciated financial position" held by the Portfolio
under Section 1259 of the Code. Any net mark-to-market gains and/or gains from
constructive sales may also have to be distributed by the STAR Series to satisfy
the distribution requirements referred to above even though no corresponding
cash amounts may concurrently be received, possibly requiring the disposition of
portfolio securities or borrowing to obtain the necessary cash. Also, certain
losses on transactions involving options, futures or forward contracts and/or
offsetting or successor positions may be deferred rather than being taken into
account currently in calculating the STAR Series' taxable income or gain.
Certain of the applicable tax rules may be modified if the STAR Portfolio is
eligible and chooses to make one or more of certain tax elections that may be
available. These transactions may affect the amount, timing and character of the
STAR Series' distributions to shareholders. The STAR Series will take into
account the special tax rules applicable to options, futures, forward contracts
and constructive sales in order to minimize any potential adverse tax
consequences.


                                       35
<PAGE>


The Federal income tax rules applicable to dollar rolls, certain structured or
hybrid securities, interest rate swaps, caps, floors and collars, and possibly
other investments or transactions are unclear in certain respects, and the STAR
Portfolio will account for these instruments in a manner that is intended to
allow the STAR Series and other similar investors to qualify as RICs. Due to
possible unfavorable consequences under present tax law, the STAR Portfolio does
not currently intend to acquire "residual" interests in real estate mortgage
investment conduit ("REMICs"), although it may acquire "regular" interests in
REMICs.

Distributions from a Fund's current or accumulated earnings and profits ("E&P"),
as computed for Federal income tax purposes, will be taxable as described in the
Prospectus whether taken in shares or in cash. Distributions, if any, in excess
of E&P will constitute a return of capital, which will first reduce an
investor's tax basis in Fund shares and thereafter (after such basis is reduced
to zero) will generally give rise to capital gains. Shareholders electing to
receive distributions in the form of additional shares will have a cost basis
for federal income tax purposes in each share so received equal to the amount of
cash they would have received had they elected to receive the distributions in
cash, divided by the number of shares received. As a result of the enactment of
the Taxpayer Relief Act of 1997 (the "1997 TRA") on August 5, 1997, gain
recognized after May 6, 1997 from the sale of a capital asset is taxable to
individual (noncorporate) investors at different maximum federal income tax
rates, depending generally upon the tax holding period for the asset, the
federal income tax bracket of the taxpayer, and the dates the asset was acquired
and/or sold. The Treasury Department has issued guidance under the 1997 TRA that
(subject to possible modification by any "technical corrections" that may be
enacted) will enable the Funds to pass through to their shareholders the
benefits of the capital gains tax rates contained in the 1997 TRA. Shareholders
should consult their own tax advisers on the correct application of these new
rules in their particular circumstances.

It is anticipated that, due to the nature of each Portfolio's investments, no
portion of any Fund's distributions will generally qualify for the dividends
received deduction. A Fund's distributions to its corporate shareholders would
potentially qualify in their hands for the corporate dividends received
deduction, subject to certain holding period requirements and limitations on
debt financing under the Code, only to the extent the Fund was allocated
dividend income of its corresponding Portfolio from stock investments in U.S.
domestic corporations.

At the time of an investor's purchase of STAR Series shares, a portion of the
purchase price may be attributable to undistributed realized or unrealized
appreciation in the STAR Series' share of the STAR Portfolio's portfolio.
Consequently, subsequent distributions by the STAR Series on such shares from
such appreciation may be taxable to such investor even if the NAV of the
investor's shares is, as a result of the distributions, reduced below the
investor's cost for such shares, and the distributions economically represent a
return of a portion of the purchase price.

Upon a redemption or other disposition of shares of the STAR Series in a
transaction that is treated as a sale for tax purposes, a shareholder may
realize a taxable gain or loss, depending upon the difference between the
redemption proceeds and the shareholder's tax basis in his shares. Such gain or
loss will generally be treated as capital gain or loss if the shares are capital
assets in the shareholder's hands. Any loss realized on a redemption may be
disallowed to the 


                                       36
<PAGE>


extent the shares disposed of are replaced with other shares of the STAR Series
within a period of 61 days beginning 30 days before and ending 30 days after the
shares are disposed of, such as pursuant to automatic dividend reinvestments. In
such a case, the basis of the shares acquired will be adjusted to reflect the
disallowed loss. Any loss realized upon the redemption of shares with a tax
holding period of six months or less will be treated as a long-term capital loss
to the extent of any amounts treated as distributions of long-term capital gain
with respect to such shares. Shareholders should consult their own tax advisers
regarding their particular circumstances to determine whether a disposition of
Fund shares is properly treated as a sale for tax purposes, as is assumed in the
foregoing discussion. Also, future Treasury Department regulations issued to
implement the 1997 TRA may contain rules for determining different tax rates
applicable to sales of Fund shares held for more than one year, more than 18
months, and (for certain sales after the year 2000 or the year 2005) more than
five years. These regulations may also modify some of the provisions described
above.

Dividends and certain other distributions may be subject to "backup withholding"
of federal income tax at a 31% rate for shareholders who fail to provide
required taxpayer identification numbers or related certifications, provide
incorrect information, or are otherwise subject to such withholding.

Different tax treatment, including penalties on certain excess contributions and
deferrals, certain pre-retirement and post-retirement distributions and certain
prohibited transactions, is accorded to accounts maintained as qualified
retirement plans. Shareholders should consult their tax adviser for more
information.

The STAR Portfolio may be subject to withholding and other taxes imposed by
foreign countries with respect to any investments in foreign securities, and the
STAR Series does not expect to pass its share of such taxes or any related
deductions or credits through to its shareholders. Foreign exchange gains and
losses may be recognized by the STAR Portfolio in connection with hybrid or
structured securities or Strategic Transactions in which its return is dependent
upon changes in the value of a foreign currency. Such gains or losses may be
subject in particular cases to Section 988 of the Code, which generally would
cause them to be treated as ordinary income and losses and could affect the
amount, timing and character of the STAR Series' distributions to its
shareholders.

The foregoing discussion relates solely to U.S. Federal income tax law as
applicable to U.S. persons (i.e., U.S. citizens or residents and U.S. domestic
corporations, partnerships, trusts or estates) subject to tax under such law.
The discussion does not address special tax rules applicable to any foreign
investors (who may be subject to withholding or other taxes) or certain other
classes of investors, such as tax-exempt entities, insurance companies, and
financial institutions. Dividends, capital gain distributions, and ownership of
or gains realized on the redemption (including an exchange) of Fund shares may
also be subject to state and local taxes. A state income (and possibly local
income and/or intangible property) tax exemption is generally available to the
extent, if any, the Fund's distributions are derived from interest on (or, in
the case of intangible property taxes, the value of its assets is attributable
to) investments in certain U.S. Government Securities, provided in some states
that certain thresholds for holdings of such 


                                       37
<PAGE>


obligations and/or reporting requirements are satisfied. Shareholders should
consult their tax advisers regarding the applicable requirements in their
particular states, including the effect, if any, of the Fund's indirect
ownership (through the Portfolio) of any such obligations, the Federal, and any
other state or local, tax consequences of ownership of shares of, and receipt of
distributions from, the Fund in their particular circumstances.

                         Calculation of Performance Data

   
As indicated in the Prospectus, from time to time, the Cash Series, the Treasury
Plus Series and the Treasury Series may quote their "yield" and "effective
yield" and the STAR Series may quote certain "total return," "yield" and
"yield-to-maturity" information in advertisements, reports and other
communications to shareholders and compare their performance figures to those of
other funds or accounts with similar objectives and to relevant indices. Such
performance information will be calculated as described below. Yield quotations
are expressed in annualized terms and may be quoted on a compounded basis.

Yield

The current yield for the Cash Series, the Treasury Plus Series and the Treasury
Series is computed by (a) determining the net change in the value of a
hypothetical pre-existing account in the Fund having a balance of one share at
the beginning of a seven calendar day period for which yield is to be quoted;
(b) dividing the net change by the value of the account at the beginning of the
period to obtain the base period return; and (c) annualizing the results (i.e.,
multiplying the base period return by 365/7).

The STAR Series' yield is computed by dividing the net investment income per
share earned during a base period of 30 days, or one month, by the maximum
offering price per share on the last day of the period. For the purpose of
determining net investment income, the calculation includes, among expenses of
the Fund, all recurring fees that are charged to all shareholder accounts and
any non-recurring charges for the period stated. In particular, yield is
determined according to the following formula:

Yield = 2[(A - B + 1)(6) - 1]
- -----------------------------
                 CD

Where:
         A=interest earned during the period; B=net expenses accrued for the
         period; C=the average daily number of shares outstanding during the
         period that were entitled to receive dividends; D=the maximum offering
         price (net asset value) per share on the last day of the period.

Effective Yield

In addition, the Cash Series, the Treasury Plus Series and the Treasury Series
may calculate a 


                                       38
<PAGE>


compound effective annualized yield by determining the net change in the value
of a hypothetical pre-existing account in the Fund having a balance of one share
at the beginning of a seven calendar day period for which yield is to be quoted
according to the following formula:

   Effective Yield = [( Base Period return +1 ) (365/7 exponentional power)] - 1
   (I.E., adding 1 to the base period return (calculated as described
   above), raising the sum to a power equal to 365/7 and subtracting 1.)

The net change in the value of the account reflects the value of additional
shares, but does not include realized gains and losses or unrealized
appreciation and depreciation.
    

Total Return

The average annual total return of the STAR Series for a period is computed by
subtracting the NAV per share at the beginning of the period from the NAV per
share at the end of the period (after adjusting for the reinvestment of any
income dividends and capital gain distributions), and dividing the result by the
NAV per share at the beginning of the period. In particular, the STAR Series'
average annual total return ("T") is computed by using the redeemable value at
the end of a specified period of time ("ERV") of a hypothetical initial
investment of $1,000 ("P") over a period of time ("n") according to the formula
P(1+T)n=ERV.

The STAR Series may also quote non-standardized yield, such as yield-to-maturity
("YTM"). YTM represents the rate of return an investor will receive if a
long-term, interest bearing investment, such as a bond, is held to its maturity
date. YTM does not take into account purchase price, redemption value, time to
maturity, coupon yield and the time between interest payments.

With respect to the treatment of discount and premium on mortgage or other
receivables-backed obligations which are expected to be subject to monthly
payments of principal and interest ("pay downs"), the STAR Portfolio accounts
for gain or loss attributable to actual monthly pay downs as an increase or
decrease to interest income during the period. In addition, the STAR Portfolio
may elect (i) to amortize the discount or premium remaining on a security, based
on the cost of the security, to the weighted average maturity date, if such
information is available, or to the remaining term of the security, if the
weighted average maturity date is not available, or (ii) not to amortize the
discount or premium remaining on a security.

In addition to average annual return quotations, the STAR Series may quote
quarterly and annual performance on a net (with management and administration
fees deducted) and gross basis. The STAR Series may also from time to time
advertise total return on a cumulative, average, year-by-year or other basis for
various specified periods by means of quotations, charts, graphs or schedules.

Past performance quotations should not be considered as representative of any
Fund's performance for any specified period in the future. The Funds'
performance may be compared in sales literature to the performance of other
mutual funds having similar objectives or to standardized indices or other
measures of investment performance. In particular, the STAR 


                                       39
<PAGE>


Series may compare its performance to The IBC/Donoghue Money Market Average/All
Taxable Index, which is generally considered to be representative of the
performance of domestic, taxable money market funds, and the One Year Treasury
Bills. However, the average maturity of the STAR Series' portfolio is longer
than that of a money market fund and, unlike a money market fund, the NAV of the
STAR Series' shares may fluctuate.

Comparative performance may also be expressed by reference to a ranking prepared
by a mutual fund monitoring service or by one or more newspapers, newsletters or
financial periodicals. Performance comparisons may be useful to investors who
wish to compare a Fund's past performance to that of other mutual funds and
investment products. Of course, past performance is not a guarantee of future
results.

Each Fund is newly organized and has limited performance history. However,
another fund in the Standish Group of Funds currently invests all of its
investable assets in the STAR Portfolio. This fund, which has substantially the
same investment objective, policies and restrictions as the STAR Portfolio and
the STAR Series. This fund is referred to in this Statement of Additional
Information as a "Corresponding Fund." In accordance with positions expressed by
the staff of the SEC, the STAR Series has adopted the performance record of the
corresponding fund for periods prior to the STAR Series' commencement of
operations. Any quotation of performance data of the STAR Series relating to
these periods will include the performance record for the Corresponding Fund for
these periods. However, because the STAR Series incurs a service fee payable at
the annual rate equal to up to 0.25% of the Fund's average daily net assets,
which service fee is not incurred by the Corresponding Fund, such quotation of
performance will be adjusted downward to reflect the imposition of such service
fee. In addition, to the extent that the net assets of the STAR Series are lower
than the net assets of the Corresponding Fund, fixed expenses incurred by the
STAR Series would be higher as a percentage of average net assets than for the
corresponding fund. See "Investment Advisory Services" and "Distributor" in this
SAI for a description of the STAR Series' expenses. The Corresponding Fund's
performance record adopted by the STAR Series has not been adjusted to reflect
any higher relative expenses, other than the service fees, expected to be
incurred by the STAR Series. The STAR Series' performance would be lower if
adjusted to reflect any higher relative additional expenses.

The Corresponding Fund's average annual total return for the one-, five- and
ten-year (or life-of-the-Fund, if shorter) periods ended on December 31, 1997
(adjusted to reflect the imposition of a service fee, distribution fee and other
estimated expenses of the STAR Series as discussed above) were as follows:

adjustment for service fees), and 5.41% (with adjustment for service and

ITEM 26.  NUMBER OF HOLDERS OF SECURITIES.

None.

ITEM 27.  INDEMNIFICATION.

Under Article VI, Section 6.4 of the Registrant's Master Trust Agreement to the
fullest extent permitted by law, the Trust shall indemnify (from the assets of
the Sub-Trust or Sub-Trusts in question) each of its Trustees and officers
(including persons who serve at the Trust's request as directors, officers or
trustees of another organization in which the Trust has any interest as a
shareholder, creditor or otherwise [hereinafter referred to as a "Covered
Person"]) against all liabilities, including but not limited to amounts paid in
satisfaction of judgments, in compromise or as fines and penalties, and
expenses, including reasonable accountants' and counsel fees, incurred by any
Covered Person in connection with the defense or disposition of any action, suit
or other proceeding, whether civil or criminal, before any court or
administrative body, in which such Covered Person may be or may have been
involved as a party or otherwise or with which such person may be or may have
been threatened, while in office or thereafter, by reason of being or having
been such a Trustee or officer, director or trustee, except with respect to any
matter as to which it has been determined that such Covered Person had acted
with willful misfeasance, bad faith, gross negligence or reckless disregard of
the duties involved in the conduct of such Covered Person's office (such conduct
referred to hereafter as "Disabling Conduct"). A determination that the Covered
Person is entitled to indemnification may be made by (i) a final decision on the
merits by a court or

<PAGE>


other body before whom the proceeding was brought that the person to be
indemnified was not liable by reason of Disabling Conduct, (ii) dismissal of a
court action or an administrative proceeding against a Covered Person for
insufficiency of evidence of Disabling Conduct, or (iii) a reasonable
determination, based upon a review of the facts, that the Covered Person was not
liable by reason of Disabling Conduct by (a) a vote of a majority of a quorum of
Trustees who are neither "interested persons" of the Trust as defined in Section
2(a)(19) of the 1940 Act nor parties to the proceeding, or (b) an independent
legal counsel in a written opinion. Expenses, including accountants' and counsel
fees so incurred by any such Covered Person (but excluding amounts paid in
satisfaction of judgments, in compromise or as fines or penalties), may be paid
from time to time from funds attributable to the Sub-Trust in question in
advance of the final disposition of any such action, suit or proceeding,
provided that the Covered Person shall have undertaken to repay the amounts so
paid to the Sub-Trust in question if it is ultimately determined that
indemnification of such expenses is not authorized under this Article VI and (i)
the Covered Person shall have provided security for such undertaking, (ii) the
Trust shall be insured against losses arising by reason of any lawful advances,
or (iii) a majority of a quorum of the disinterested Trustees who are not a
party to the proceeding, or an independent legal counsel in a written opinion,
shall have determined, based on a review of readily available facts (as opposed
to a full trial-type inquiry), that there is reason to believe that the Covered
Person ultimately will be found entitled to indemnification.

Insofar as indemnification for liability arising under the Securities Act of
1933, as amended (the "1933 Act"), may be permitted to Trustees, officers and
controlling persons of the Trust pursuant to the foregoing provisions, or
otherwise, the Trust has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the 1933 Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Trust of expenses incurred or
paid by a Trustee, officer or controlling person of the Trust in the successful
defense of any action, suit or proceeding) is asserted by such Trustee, officer
or controlling person in connection with the securities being registered, the
Trust will, unless in the opinion of its counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the 1933 Act and will be governed by the final adjudication of such
issue.

ITEM 28.  BUSINESS AND OTHER CONNECTIONS OF INVESTMENT ADVISER.

   
Investors Bank serves as investment adviser to the Merrimac Cash Portfolio, the
Merrimac Treasury Plus Portfolio and the Merrimac Treasury Portfolio. Investors
Bank was organized in 1969 as a Massachusetts-chartered trust company and
provides domestic and global custody, multi-currency accounting, institutional
transfer agency, performance measurement, foreign exchange, securities lending,
mutual fund administration and investment advisory services to a variety of
financial asset managers, including mutual fund complexes, investment advisers,
banks and insurance companies. The business, profession, vocation or employment
of a substantial nature that each director or officer of Investors Bank is or
has been, at any time during the past two fiscal years, engaged in for his own
account or in the capacity of director, officer, employee, partner or trustee,
is as follows:

         WHEREAS, the Merrimac Treasury Portfolio (the "Portfolio") is a series
of the Trust, which is an open-end diversified management investment company
registered as such with the Securities and Exchange Commission (the "SEC")
pursuant to the Investment Company Act of 1940, as amended (the "1940 Act");

         WHEREAS, the Merrimac Treasury Fund (the "Fund"), which is an open-end
diversified management investment company registered as such with the SEC
pursuant to the 1940 Act, will invest all of its investable assets in the
Portfolio;

         WHEREAS, the Trust, on behalf of the Portfolio, desires to appoint the
Adviser to render, or contract to obtain as hereinafter provided, investment
advisory services to the Portfolio and to administer the Portfolio's day to day
business affairs and the Adviser is willing to act in such capacity upon the
terms herein set forth;

         NOW THEREFORE, in consideration of the premises and of the mutual
covenants herein contained, the Trust, on behalf of the Portfolio, and the
Adviser, the parties hereto, intending to be legally bound, hereby agree as
follows:

Appointment

         (a) The Trust, on behalf of the Portfolio, hereby appoints the Adviser
as the investment adviser of the Portfolio to administer its business affairs
and to perform for the Portfolio such other duties and functions as are
hereinafter set forth. The Adviser hereby accepts such appointment and agrees to

benefit of the Adviser's best judgment, effort, advice and recommendations in
respect of its duties as defined in Section 2.

         (b) The Trust hereby represents and warrants to the Adviser, which
representations and warranties shall be deemed to be continuing, that (i) it has
full power and authority to enter into this Agreement, and (ii) it has taken all
necessary and proper action to authorize the execution and delivery of this
Agreement.

         (c) The Adviser hereby represents and warrants to the Trust, which
representations and warranties shall be deemed to be continuing, that (i) it has
full power and authority to enter into this Agreement, and (ii) it has taken all
necessary and proper action to authorize the execution and delivery of this
Agreement.

2.  Adviser Duties

         (a) The Adviser shall, subject to the direction and control of the
Trustees and in accordance with the objective and policies of the Portfolio and
the implementation thereof as set forth in the Fund's Confidential Offering
Circular, the Portfolio's Registration Statement on Form N-1A and any federal
and state laws: (i) regularly provide investment advice and recommendations to

and the purchase and sale of securities; (ii) supervise and monitor continuously
the investment program of the Portfolio and the composition of its portfolio and
determine what securities shall be purchased and sold by the Portfolio; (iii)
arrange, subject to the provision of Section 4 hereof, for the purchase of
securities and other investments for the Portfolio and the sale of securities
and other investments of the Portfolio; (iv) provide reports on the foregoing to

order to permit the Trust to determine the adherence by the Adviser to the
investment policies and legal requirements of the Portfolio; and (v) make 


<PAGE>


its officers and employees available to the Trust's officers at reasonable times
to review the investment policies of the Portfolio and to consult with the
Trust's officers regarding the investment affairs of the Portfolio.

         (b) The Adviser is further authorized to enter into a sub-adviser
arrangement for the investment advisory services outlined in Section 2 (a) of
this Agreement in connection with the management of the Portfolio, provided that
no such arrangement shall be made until a sub-adviser agreement has been
approved by the Trustees. Should the Adviser enter into such a sub-adviser
agreement, the Adviser shall, nevertheless, retain supervisory responsibility
for all investment advisory services furnished pursuant to a ny such
sub-advisory arrangements and the Adviser's duties shall then include: (i)
supervise and monitor continuously the investment advisory services furnished
pursuant to any such sub-adviser arrangements; (ii) review the performance of
the sub-adviser, and make recommendations to the Trustees with respect to the
retention and renewal of such sub-adviser arrangements; (iii) provide reports on
the foregoing to the Trustees for each Board meeting; (iv) make its officers and
employees available to review the investment policies of the Portfolio and to
consult with the sub-adviser regarding the investment affairs of the Portfolio;
(v) supervise relationships with and monitor the performance of the custodian,
depositories, transfer agent, accountants, attorneys, insurers and other persons
in any capacity deemed to be necessary or desirable; and (vi) make
recommendations to the Trustees with respect to Portfolio policies and carry out
such policies as are adopted by the Trustees.

3. Compensation of the Adviser

         The Portfolio will pay to the Adviser as compensation for the Adviser's
services rendered and for the expenses borne by the Adviser, including personnel
expenses, a fee, determined as described in Schedule A which is attached hereto
and made a part hereof.

4.  Portfolio Transactions and Brokerage

         The Adviser shall place all orders for the purchase and sale of
portfolio securities for the Portfolio's account with issuers, brokers or
dealers selected by the Adviser, which may include where permissible under the
1940 Act, brokers or dealers affiliated with the Adviser. In the selection of
such brokers or dealers and the placing of such orders, the Adviser always shall
seek best execution, which is to place transactions where the Portfolio can
obtain the most favorable combination of price and execution services in
particular transactions or provided on a continuing basis by a broker or dealer,
and to deal directly with a principal market in connection with over-the-counter
transactions, except when it is believed that best execution is obtainable
elsewhere.

Agreement are not binding upon any Trustee or shareholder of the Trust
personally, but bind only the Trust and the Trust's property.

other party may designate for the receipt of such notice. No notice shall be

<PAGE>


hereto and made a part hereof. Such fee shall be paid by the Adviser and the
Trust shall have no liability therefor.

5.  Portfolio Transactions and Brokerage
- ----------------------------------------

The Sub-Adviser shall place all orders for the purchase and sale of portfolio
securities for the Portfolio's account with issuers, brokers or dealers selected
by the Sub-Adviser, which may include where permissible under the 1940 Act,
brokers or dealers affiliated with the Sub-Adviser. In the selection of such
brokers or dealers and the placing of such orders, the Adviser always shall seek
best execution, which is to place transactions where the Portfolio can obtain
the most favorable combination of price and execution services in particular
transactions or provided on a continuing basis by a broker or dealer, and to
deal directly with a principal market in connection with over-the-counter
transactions, except when it is believed that best execution is obtainable
elsewhere. Nothing in this Agreement shall preclude the combining of orders for
the sale or purchase of securities or other investments with other accounts
managed by the Sub-Adviser or its affiliates, provided that the Sub-Adviser does
not favor any account over any other account and provided that any purchase or
sale orders executed contemporaneously shall be allocated in an equitable manner
among the accounts involved in accordance with procedures adopted by the
Sub-Adviser and reviewed and approved by the Adviser.

6.  Interested Trustees or Parties
- ----------------------------------

It is understood that Trustees, officers, and shareholders of the Trust may be
or become interested in the Adviser or the Sub-Adviser as directors, officers or
employees and that directors, officers and stockholders of the Adviser or the
Sub-Adviser may be or become similarly interested in the Trust, and that the
Adviser or the Sub-Adviser may be or become interested in the Trust as a
shareholder or otherwise.

7.  Services Not Exclusive
- --------------------------

The services of the Sub-Adviser to the Adviser are not to be deemed exclusive,
the Sub-Adviser being free to render services to others and engage in other
activities, provided, however, that such other services and activities do not,
during the term of this Agreement, interfere, in a material manner, with the
Sub-Adviser's ability to meet all of its obligations with respect to rendering
investment advice hereunder. The Sub-Adviser, its affiliates and its other
clients may at any time acquire or dispose of securities which are at the same
time being acquired or disposed of for the account of the Portfolio. The
Sub-Adviser shall not be obligated to acquire for the Portfolio any security or
other investment which the Sub-Adviser or its affiliates may acquire for its or
their own accounts or for the account of another client.

8.  Compliance;  Books and Records
- ----------------------------------

           (a) The Sub-Adviser agrees to maintain compliance procedures which
           are reasonably designed to ensure the Portfolio's compliance with the
           applicable provisions of the 1940 Act and any rules or regulations
           thereunder and the investment objective, policies and restrictions of
           the Portfolio as set forth in the current Investor Offering Documents
           or any other applicable provisions or state or federal law.

           (b) The Sub-Adviser shall furnish to the Adviser, at the Adviser's
           expense, copies of all records prepared and maintained in connection
           with the performance of this Agreement and the maintenance of
           compliance procedures pursuant to this Section 8 as the Adviser may
           reasonably request. 


                                       4

<PAGE>


           (c) The Sub-Adviser agrees to provide upon reasonable request of
           the Adviser, information regarding the Sub-Adviser, including but
           not limited to, background information about the Sub-Adviser and
           its personnel and performance data, for use in connection with
           efforts to promote the Fund and the sale of its shares.

           (d) In compliance with the requirements of Rule 31a-3 under the 1940
           Act, the Sub-Adviser hereby agrees that all records which it
           maintains for the Trust are the property of the Trust and further
           agrees to surrender promptly to the Trust any of such records upon
           the Trust's request. The Sub-Adviser further agrees to preserve for
           the periods prescribed by Rule 31a-2 under the 1940 Act any records
           which it is required to maintain by Rule 31a-1 under the 1940 Act.
           The Sub-Adviser will treat confidentially and as proprietary
           information of the Trust all records and other information obtained
           from the Trust relative to the Authorized Investors and prior or
           potential shareholders, except as otherwise required by law.

9.  Limitation of Liability of Sub-Adviser; Indemnification
- -----------------------------------------------------------

In consideration of the Sub-Adviser's undertaking to render the services
described in this Agreement, the Adviser agrees that the Sub-Adviser shall not
be liable for any loss suffered by the Adviser, the Trust, the Authorized
Investors or their shareholders, or the Portfolio in connection with the
performance of this Agreement, provided that nothing in this Agreement shall be
deemed to protect or purport to protect the Sub-Adviser against any liability to
the Adviser, the Trust, the Authorized Investors or their shareholders, or the
Portfolio to which the Sub-Adviser would otherwise be subject by reason of
willful misfeasance, bad faith or negligence in the performance of its duties
under this Agreement.

10.  Duration, Amendment and Termination
- ----------------------------------------

           (a) Subject to prior termination as provided in sub-section (d) of
           this Section 10, this Agreement shall continue in effect until two
           years from the date hereof and for successive annual periods
           thereafter, but only so long as the continuance after such initial
           two year period shall be specifically approved at least annually by
           vote of the Board of Trustees or by vote of a majority of the
           outstanding voting securities of the Portfolio and the Authorized
           Investors.

           (b) This Agreement may be modified by the written agreement of the

           of the Portfolio to be authorized by vote of a majority of the
           outstanding voting securities of the Portfolio and the Authorized
           Investors if required by law. The execution of any such modification
           or amendment by a party shall constitute a representation and
           warranty to the other parties that all necessary consents or
           approvals with respect to such modification or amendment have been
           obtained.

           (c) In addition to the requirements of sub-sections (a) and (b) of
           this Section 10, the terms of any continuance, modification or
           amendment of the Agreement must have been approved by the vote of a
           majority of those Trustees who are not parties to such Agreement or
           interested persons of any such party, cast in person at a meeting
           called for the purpose of voting on such approval.

           (d) Either the Adviser, the Sub-Adviser or the Portfolio may, at any
           time on sixty (60) days' prior written notice to the other parties,
           terminate this Agreement, without payment of any penalty, and in the
           case of the Portfolio, by action of its Board of Trustees, or by vote
           of a majority of its outstanding voting securities.


                                       5

            (e) This Agreement shall terminate automatically in the event of its
            assignment.

            (f) Termination of this Agreement shall not relieve the Adviser
            nor the Sub-Adviser from any liability or obligation in respect of
            any matters, undertakings or conditions which shall not have been
            done, observed or performed prior to such termination. All records
            of the Portfolio in the possession of the Sub-Adviser shall be
            returned to the Portfolio as soon as reasonably practicable after
            the termination of this Agreement.

11.  Disclaimer of Shareholder Liability
- ----------------------------------------

The Adviser and the Sub-Adviser understand that the obligations of the Trust
under this Agreement are not binding upon any Trustee or shareholder of the
Trust personally, but bind only the Trust and the Trust's property.

           securities," "assignment," and "interested persons," when used

Funds Distributor, Inc.
60 State Street
Suite 1300
Boston, Massachusetts 02109

Dear Sirs:

     This is to confirm that, in consideration of the agreements hereinafter
contained, the above-named investment company (the "Fund") has agreed that you
shall be, for the period of this Agreement, the distributor of (a) shares of
each Series of the Fund set forth on Exhibit A hereto, as such Exhibit may be
revised from time to time (each, a "Series") or (b) if no Series are set forth
on such Exhibit, shares of the Fund. For purposes of this Agreement the term
"Shares" shall mean the authorized shares of the relevant Series, if any, and
otherwise shall mean the Fund's authorized shares.

     1. Services as Distributor

     1.1 You will act as agent for the distribution of Shares covered by, and in
accordance with, the registration statement and prospectus then in effect under
the Securities Act of 1933, as amended (the "1933 Act"), and will transmit
promptly any orders received by you for purchase or redemption of Shares to the
Transfer and Dividend Disbursing Agent for the Fund of which the Fund has
notified you in writing.

     1.2 You agree to use your best efforts to solicit orders for the sale of
Shares. It is contemplated that you may enter into sales or servicing agreements
with securities dealers, financial institutions and other industry
professionals, such as investment advisers, accountants and estate planning
firms, and in so doing you will act only on your own behalf as principal.

     1.3 You shall act as distributor of Shares in compliance with all
applicable laws, rules and regulations, including, without limitations, the
Investment Company Act of 1940, as amended (the "1940 Act"), the 1933 Act, the
Securities Exchange Act of 1934, as amended and the National Association of
Securities Dealers, Inc.'s (the "NASD") Conduct Rules, Constitution and By-Laws.
You represent and warrant that you are a broker-dealer registered with the
Securities and Exchange Commission (the "SEC") and that you are registered with
the relevant

                                       1
<PAGE>


securities regulatory agencies in all fifty states, the District of Columbia
and Puerto Rico. You also represent and warrant that you are a member of the
NASD.

     1.4 You shall file Fund advertisements, sales literature and other
marketing and sales related materials with the appropriate regulatory agencies
and shall obtain such approvals for their use as may be required by the SEC, the
NASD and/or state securities administrators.

     1.5 Whenever in their judgment such action is warranted by unusual market,
economic or political conditions, or by abnormal circumstances of any kind
deemed by the parties hereto to render sales of a Fund's Shares not in the best
interest of the Fund, the parties hereto may decline to accept any orders for,
or make any sales of, any Shares until such time as those parties deem it
advisable to accept such orders and to make such sales and each party shall
advise promptly the other party of any such determination.

     1.6 The Fund agrees to pay all costs and expenses in connection with the
registration of Shares under the 1933 Act and all expenses in connection with
maintaining facilities for the issue and transfer of Shares and for supplying
information, prices and other data to be furnished by the Fund hereunder, and
all expenses in connection with the preparation and printing of the Fund's
prospectuses and statements of additional information for regulatory purposes
and for distribution to shareholders; provided however, that the Fund shall not
pay any of the costs of advertising or promotion for the sale of Shares, except
as authorized by a plan adopted pursuant to Rule 12b-1 under the 1940 Act. You
shall also be entitled to compensation for your services as provided in any
Distribution Plan adopted as to any Series and class of the Fund's Shares
pursuant to Rule 12b-1.

     1.7 The Fund agrees to execute any and all documents and to furnish any and
all information and otherwise to take all actions which may be reasonably
necessary in the discretion of the Fund's officers in connection with the
qualification of Shares for sale in such states as you may designate to the Fund
and the Fund may approve, and the Fund agrees to pay all expenses which may be
incurred in connection with such qualification. You shall pay all expenses
connected with your own qualification as a dealer under state or Federal laws
and, except as otherwise specifically provided in this Agreement, all other
expenses incurred by you in connection with the sale of Shares as contemplated
in this Agreement.

     1.8 The Fund shall furnish you from time to time, for use in connection
with the sale of Shares, such information with respect to the Fund or any
relevant Series and the Shares as you may reasonably request, all of which shall
be signed by one or more of the Fund's duly authorized officers; and the Fund
warrants that the statements contained in any such information, when so signed
by the Fund's officers, shall be true and correct. The Fund also shall furnish
you upon request with: (a) semi-annual reports and annual audited reports of the
Fund's books and accounts made by independent public accountants regularly
retained by the Fund, (b) quarterly earnings statements prepared by the Fund,
(c) a monthly itemized list of the securities in the Fund's or, if applicable,
each Series' portfolio, (d) monthly balance sheets as soon as practicable after
the end of each month, and (e) from time to time such additional information
regarding the Fund's financial condition as you may reasonably request.

     1.9 The Fund represents to you that all registration statements and
prospectuses filed by the Fund with the SEC under the 1933 Act and under the
1940 Act with respect to the Shares have been carefully prepared in conformity
with the requirements of said Acts and rules and regulations of the SEC
thereunder. As used in this Agreement the terms "registration statement" and
"prospectus" shall mean any registration statement and prospectus, including the
statement of additional information incorporated by reference therein, filed
with the SEC and any amendments and supplements thereto which at any time shall
have been filed with the SEC. The Fund represents and warrants to you that any
registration statement and prospectus, when such registration statement becomes
effective, will contain all statements required to be stated therein in
conformity with said Acts and the rules and regulations of the SEC; that all
statements of fact contained in any such registration statement and prospectus
will be true and correct when such registration statement becomes effective; and
that neither any registration statement nor any prospectus when such
registration statement becomes effective will include an untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein not misleading. The Fund may, but shall
not be obligated to, propose from time to time such amendment or amendments to
any registration statement and such supplement or supplements to any prospectus
as, in the light of future developments, may, in the opinion of the Fund's
counsel, be necessary or advisable. If the Fund shall not propose such amendment
or amendments and/or supplement or supplements within fifteen days after receipt
by the Fund of a written request from you to do so, you may, at your option,
terminate this Agreement or decline to make offers of the Fund's securities
until such amendments are made. The Fund shall not file any amendment to any
registration statement or supplement to any prospectus without giving you
reasonable notice thereof in advance; provided, however, that nothing contained
in this Agreement shall in any way limit the Fund's right to file at any time
such amendments to any registration statement and/or supplements to any
prospectus, of whatever character, as the Fund may deem advisable, such right
being in all respects absolute and unconditional.

     1.10 The Fund authorizes you and any dealers with whom you have entered
into dealer agreements to use any prospectus in the form furnished by the Fund
in connection with the sale of Shares. The Fund agrees to indemnify, defend and
hold you, your several officers and directors, and any person who controls you
within the meaning of Section 15 of the 1933 Act free and harmless from and
against any and all claims, demands, liabilities and expenses (including the
reasonable cost of investigating or defending such claims, demands or
liabilities and any reasonable counsel fees incurred in connection therewith)
which you, your officers and directors, or any such controlling persons, may
incur under the 1933 Act, the 1940 Act, or common law or otherwise, arising out
of or on the basis of any untrue statement, or alleged untrue statement, of a
material fact required to be stated in either any registration statement or any
prospectus or any statement of additional information, or arising out of or
based upon any omission, or alleged omission, to state a material fact required
to be stated in any registration statement, any prospectus or any statement of
additional information or necessary to make the statements in any of them not
misleading, except that the Fund's agreement to indemnify you, your officers or
directors, and any such controlling person will not be deemed to cover any such
claim, demand, liability or expense to the extent that it arises out of or is
based upon any such untrue statement, alleged untrue statement, omission or
alleged omission made in any registration statement, any prospectus or any
statement of additional information in reliance upon information furnished by
you, your officers, directors or any such controlling person to the Fund

                                       3
<PAGE>

or its representatives for use in the preparation thereof, and except that the
Fund's agreement to indemnify you and the Fund's representations and warranties
set out in paragraph 1.9 of this Agreement will not be deemed to cover any
liability to the Funds or their shareholders to which you would otherwise be
subject by reason of willful misfeasance, bad faith or gross negligence in the
performance of your duties, or by reason of your reckless disregard of your
obligations and duties under this Agreement ("Disqualifying Conduct"). The
Fund's agreement to indemnify you, your officers and directors, and any such
controlling person, as aforesaid, is expressly conditioned upon the Fund's being
notified of any action brought against you, your officers or directors, or any
such controlling person, such notification to be given by letter, by facsimile
or by telegram addressed to the Fund at its address set forth above within a
reasonable period of time after the summons or other first legal process shall
have been served. The failure so to notify the Fund of any such action shall not
relieve the Fund from any liability which the Fund may have to the person
against whom such action is brought by reason of any such untrue, or alleged
untrue, statement or omission, or alleged omission, otherwise than on account of
the Fund's indemnity agreement contained in this paragraph 1.10. The Fund will
be entitled to assume the defense of any suit brought to enforce any such claim,
demand or liability, but, in such case, such defense shall be conducted by
counsel of good standing chosen by the Fund and approved by you. In the event
the Fund elects to assume the defense of any such suit and retain counsel of
good standing approved by you, the defendant or defendants in such suit shall
bear the fees and expenses of any additional counsel retained by any of them;
but in case the Fund does not elect to assume the defense of any such suit, the
Fund will reimburse you, your officers and directors, or the controlling person
or persons named as defendant or defendants in such suit, for the reasonable
fees and expenses of any counsel retained by you or them. The Fund's
indemnification agreement contained in this paragraph 1.10 and the Fund's
representations and warranties in this Agreement shall remain operative and in
full force and effect regardless of any investigation made by or on behalf of
you, your officers and directors, or any controlling person, and shall survive
the delivery of any Shares. This agreement of indemnity will inure exclusively
to your benefit, to the benefit of your several officers and directors, and
their respective estates, and to the benefit of any controlling persons and
their successors. The Fund agrees promptly to notify you of the commencement of
any litigation or proceedings against the Fund or any of its officers or Board
members in connection with the issue and sale of Shares.

     1.11 You agree to indemnify, defend and hold the Fund, its several officers
and Board members, and any person who controls the Fund within the meaning of
Section 15 of the 1933 Act free and harmless from and against any and all
claims, demands, liabilities and expenses (including the reasonable cost of
investigating or defending such claims, demands or liabilities and any
reasonable counsel fees incurred in connection therewith) which the Fund, its
officers or Board members, or any such controlling person, may incur under the
1933 Act, the 1940 Act, or under common law or otherwise, but only to the extent
that such liability or expense incurred by the Fund, its officers or Board
members, or such controlling person resulting from such claims or demands, (a)
shall arise out of or be based upon any unauthorized sales literature,
advertisements, information, statements or representations or any Disqualifying
Conduct in connection with the offering and sale of any Shares, or (b) shall
arise out of or be based upon any untrue, or alleged untrue, statement of a
material fact contained in information furnished in writing by you to the Fund
specifically for use in the Fund's registration statement and used in the
answers to any of the items of the registration statement or in the
corresponding statements made in the prospectus or statement of additional
information, or shall arise out of or be based upon any omission, or

                                       4
<PAGE>

alleged omission, to state a material fact in connection with such information
furnished in writing by you to the Fund and required to be stated in such
answers or necessary to make such information not misleading. Your agreement to
indemnify the Fund, its officers and Board members, and any such controlling
person, as aforesaid, is expressly conditioned upon your being notified of any
action brought against the Fund, its officers or Board members, or any such
controlling person, such notification to be given by letter, by facsimile or by
telegram addressed to you at your address set forth above within a reasonable
period of time after the summons or other first legal process shall have been
served. You shall have the right to control the defense of such action, with
counsel of your own choosing, satisfactory to the Fund, if such action is based
solely upon such alleged misstatement or omission on your part, and in any other
event the Fund, its officers or Board members, or such controlling person shall
each have the right to participate in the defense or preparation of the defense
of any such action. The failure so to notify you of any such action shall not
relieve you from any liability which you may have to the Fund, its officers or
Board members, or to such controlling person by reason of any such untrue, or
alleged untrue, statement or omission, or alleged omission, otherwise than on
account of your indemnity agreement contained in this paragraph 1.11. This
agreement of indemnity will inure exclusively to the Fund's benefit, to the
benefit of the Fund's officers and Board members, and their respective estates,
and to the benefit of any controlling persons and their successors. You agree
promptly to notify the Fund of the commencement of any litigation or proceedings
against you or any of your officers or directors in connection with the issue
and sale of Shares.

     1.12 No Shares shall be offered by either you or the Fund under any of the
provisions of this Agreement and no orders for the purchase or sale of such
Shares hereunder shall be accepted by the Fund if and so long as the
effectiveness of the registration statement then in effect or any necessary
amendments thereto shall be suspended under any of the provisions of the 1933
Act, or if and so long as a current prospectus as required by Section 10 of said
Act, as amended, is not on file with the SEC; provided, however, that nothing
contained in this paragraph 1.12 shall in any way restrict or have an
application to or bearing upon the Fund's obligation to repurchase any Shares
from any shareholder in accordance with the provisions of the Fund's prospectus
or charter documents.

     1.13 The Fund agrees to advise you immediately in writing:

         (a) of any request by the SEC for amendments to the registration
     statement or prospectus then in effect or for additional information;

         (b) in the event of the issuance by the SEC of any stop order
     suspending the effectiveness of the registration statement or prospectus
     then in effect or the initiation of any proceeding for that purpose;

         (c) of the happening of any event which makes untrue any statement of a
     material fact made in the registration statement or prospectus then in
     effect or which requires the making of a change in such registration
     statement or prospectus in order to make the statements therein not
     misleading; and

         (d) of all actions of the SEC with respect to any amendments to any
     registration statement or prospectus which may from time to time be filed
     with the SEC.

                                       5
<PAGE>

     2. Offering Price

     Shares of any class of the Fund offered for sale by you shall be offered at
a price per share (the "offering price") approximately equal to (a) the net
asset value (determined in the manner set forth in the Fund's charter documents)
plus (b) a sales charge, if any and except to those persons set forth in the
then-current prospectus, which shall be the percentage of the offering price of
such Shares as set forth in the Fund's then-current prospectus. The offering
price, if not an exact multiple of one cent, shall be adjusted to the nearest
cent. In addition, Shares of any class of the Fund offered for sale by you may
be subject to a contingent deferred sales charge as set forth in the Fund's
then-current prospectus. You shall be entitled to receive any sales charge or
contingent deferred sales charge in respect of the Shares. Any payments to
dealers shall be governed by a separate agreement between you and such dealer
and the Fund's then-current prospectus.

     3. Term

     This Agreement shall become effective with respect to the Fund as of the
date hereof and will continue for an initial two-year term and will continue
thereafter so long as such continuance is specifically approved at least
annually (i) by the Fund's Board or (ii) by a vote of a majority of the Shares
of the Fund or the relevant Series, as the case may be, provided that in either
event its continuance also is approved by a majority of the Board members who
are not "interested persons" of any party to this Agreement, by vote cast in
person at a meeting called for the purpose of voting on such approval. This
Agreement is terminable with respect to a Fund, without penalty, on not less
than sixty days' notice, by the Fund's Board of Trustees, by vote of a majority
of the outstanding voting securities of such Fund, or by you. This Agreement
will automatically and immediately terminate in the event of its "assignment."
(As used in this Agreement, the terms "majority of the outstanding voting
securities," "interested person" and "assignment" shall have the same meanings
as such terms have in the 1940 Act). You agree to notify the Fund immediately
upon the event of your expulsion or suspension by the NASD. This Agreement will
automatically and immediately terminate in the event of your expulsion or
suspension by the NASD.

     4. Miscellaneous

     4.1 The Fund recognizes that, except to the extent otherwise agreed to by
the parties hereto, your directors, officers and employees may from time to time
serve as directors, trustees, officers and employees of corporations and
business trusts (including other investment companies), and that you or your
affiliates may enter into distribution or other agreements with such other
corporations and trusts.

     4.2 No provision of this Agreement may be changed, waived, discharged or
terminated orally, but only by an instrument in writing signed by the party
against which an enforcement of the change, waiver, discharge or termination is
sought.

     4.3 This Agreement shall be governed by the internal laws of the
Commonwealth of Massachusetts without giving effect to principles of conflicts
of laws.

     4.4 If any provision of this Agreement shall be held or made invalid by a
court decision, statute, rule, or otherwise, the remainder of this Agreement
shall not be affected thereby. This Agreement shall be binding upon and shall
inure to the benefit of the parties hereto and their respective successors.

     Please confirm that the foregoing is in accordance with your understanding
and indicate your acceptance hereof by signing below, whereupon it shall become
a binding agreement between us.

                                               Very truly yours,

2.8 Proper Instructions. Proper Instructions shall mean (i) instructions
regarding the purchase or sale of Portfolio Securities, and payments and

instructions to be given in such form and manner as the Bank and the Fund shall
agree upon from time to time, and (ii) instructions (which may be continuing
instructions) regarding other matters signed or initialed by an Authorized

shall cause all oral instructions to be promptly confirmed in writing. The Bank
shall act upon and comply with any subsequent Proper Instruction which modifies
a prior instruction and the sole obligation of the Bank with respect to any
follow-up or confirmatory instruction shall be to make reasonable efforts to
detect any discrepancy between the original instruction and such confirmation
and to report such discrepancy to the Fund. The Fund shall be responsible, at

to correct any such discrepancy or error, and to the extent such action requires
the Bank to act, the Fund shall give the Bank specific Proper Instructions as to
the action required. Upon receipt by the Bank of an Officers' Certificate as to

effected directly between electro-mechanical or electronic devices provided that
the Board and the Bank agree in writing that such procedures afford adequate
safeguards for the Fund's assets.

Bank will segregate the assets of each series or portfolio to which this
Agreement relates into a separate account for each such series or portfolio
containing the assets of such series or portfolio (and all investment earnings
thereon). Unless the context otherwise requires, any reference in this Agreement
to any actions to be taken by the Fund shall be deemed to refer to the Fund
acting on behalf of one or more of its series, any reference in this Agreement
to any assets of the Fund, including, without limitation, any portfolio
securities and cash and earnings thereon, shall be deemed to refer only to
assets of the applicable series, any duty or obligation of the Bank hereunder to
the Fund shall be deemed to refer to duties and obligations with respect to such
individual series and any obligation or liability of the Fund hereunder shall be
binding only with respect to such individual series, and shall be discharged
only out of the assets of such series.

4. Certification as to Authorized Persons. The Secretary or Assistant Secretary
of the Fund will at all times maintain on file with the Bank his or her
certification to the Bank, in such form as may be acceptable to the Bank, of (i)
the names and signatures of the Authorized Persons and (ii) the names of the

Portfolio Securities which may now or hereafter be delivered to it by or for the
account of the Fund. All such Portfolio Securities will be held or disposed of

defined in the Internal Revenue Code and any Regulations of the Treasury
Department issued thereunder, and will execute and deliver all such certificates
in connection therewith as may be required by such laws or regulations or under
the laws of any state.

manner in which such proxies are to be voted.

6.3 Corporate Action. If at any time the Bank is notified that an issuer of any
Portfolio Security has taken or intends to take a corporate action (a "Corporate
Action") that affects the rights, privileges, powers, preferences,
qualifications or ownership of a Portfolio Security, including without
limitation, liquidation, consolidation, merger, recapitalization,
reorganization, reclassification, subdivision, combination, stock split or stock
dividend, which Corporate Action requires an affirmative response or action on
the part of the holder of such Portfolio Security (a "Response"), the Bank shall
notify the Fund promptly of the Corporate Action, the Response required in
connection with the Corporate Action and the Bank's deadline for receipt from
the Fund of Proper Instructions regarding the Response (the "Response
Deadline"). The Bank shall forward to the Fund via telecopier and/or overnight
courier all notices, information statements or other materials relating to the
Corporate Action within twenty-four (24) hours of receipt of such materials by
the Bank.

                      (a) The Bank shall act upon a required Response only after
                      receipt by the Bank of Proper Instructions from the Fund
                      no later than 5:00 p.m. on the date specified as the
                      Response Deadline and only if the Bank (or its agent or
                      subcustodian hereunder) has actual possession of all
                      necessary Securities, consents and other materials no
                      later than 5:00 p.m. on the date specified as the Response
                      Deadline.

                      (b) The Bank shall have no duty to act upon a required
                      Response if Proper Instructions relating to such Response
                      and all necessary Securities, consents and other materials
                      are not received by and in the possession of the Bank no
                      later than 5:00 p.m. on the date specified as the Response
                      Deadline. Notwithstanding, the Bank may, in its sole
                      discretion, use its best efforts to act upon a Response
                      for which Proper Instructions and/or necessary Securities,
                      consents or other materials are received by the Bank after
                      5:00 p.m. on the date specified as the Response Deadline,
                      it being acknowledged and agreed by the parties that any
                      undertaking by the Bank to use its best efforts in such
                      circumstances shall in no way create any duty upon the
                      Bank to complete such Response prior to its expiration.

                      (c) In the event that the Fund notifies the Bank of a
                      Corporate Action requiring a Response and the Bank has
                      received no other notice of such Corporate Action, the
                      Response Deadline shall be 48 hours prior to the Response
                      expiration time set by the depository processing such
                      Corporate Action.

                              Futures and puts and calls thereon instead of

                      payment therefor in full, or against payment to the Bank
                      in accordance with generally accepted settlement practices
                      and customs in the jurisdiction or market in which the
                      transaction occurs, each such payment to be in the amount
                      of the sale price shown in a broker's confirmation of sale
                      received by the Bank before such payment is made, as
                      confirmed in the Proper Instructions received by the Bank
                      before such payment is made;

                      (b) In exchange for or upon conversion into other
                      securities alone or other securities and cash pursuant to

                      split-up, change in par value, recapitalization or
                      readjustment or otherwise, upon exercise of subscription,
                      purchase or sale or other similar rights represented by
                      such Portfolio Securities, or for the purpose of tendering
                      shares in the event of a tender offer therefor, provided,
                      however, that in the event of an offer of exchange, tender
                      offer, or other exercise of rights requiring the physical
                      tender or delivery of Portfolio Securities, the Bank shall
                      have no liability for failure to so tender in a timely
                      manner unless such Proper Instructions are received by the
                      Bank at least two business days prior to the date required
                      for tender, and unless the Bank (or its agent or
                      subcustodian hereunder) has actual possession of such
                      Security at least two business days prior to the date of
                      tender;

                      (c) Upon conversion of Portfolio Securities pursuant to
                      their terms into other securities;

                      (d) For the purpose of redeeming in-kind shares of the
                      Fund upon authorization from the Fund;

                      (e) In the case of option contracts owned by the Fund, for
                      presentation to the endorsing broker;

                      (f) When such Portfolio Securities are called, redeemed or
                      retired or otherwise become payable;

                      (g) For the purpose of effectuating the pledge of
                      Portfolio Securities held by the Bank in order to
                      collateralize loans made to the Fund by any bank,
                      including the Bank; provided, however, that such Portfolio
                      Securities will be released only upon payment to the Bank
                      for the account of the Fund of the moneys borrowed,
                      provided further, however, that in cases where additional
                      collateral is required to secure a borrowing already made,
                      and such fact is made to appear in the Proper
                      Instructions, Portfolio Securities may be released for
                      that purpose without any such payment. In the event that
                      any pledged Portfolio Securities are held by the Bank,
                      they will be so held for the account of the lender, and
                      after notice to the Fund from the lender in accordance
                      with the normal procedures of the lender and any loan
                      agreement between the fund and the lender that an event of
                      deficiency or default on the loan has occurred, the Bank
                      may deliver such pledged Portfolio Securities to or for
                      the account of the lender;

                                       11

                      (h) for the purpose of releasing certificates representing
                      Portfolio Securities, against contemporaneous receipt by
                      the Bank of the fair market value of such security, as set

                      repurchase agreement relating to such securities entered
                      into by the Fund;

                      (j) for other authorized transactions of the Fund or for
                      other proper corporate purposes; provided that before
                      making such transfer, the Bank will also receive a
                      certified copy of resolutions of the Board, signed by an
                      authorized officer of the Fund (other than the officer
                      certifying such resolution) and certified by its Secretary
                      or Assistant Secretary, specifying the Portfolio
                      Securities to be delivered, setting forth the transaction
                      in or purpose for which such delivery is to be made,
                      declaring such transaction to be an authorized transaction

                      purpose, and naming the person or persons to whom delivery
                      of such securities shall be made; and

                      (k) upon termination of this Agreement as hereinafter set
                      forth pursuant to Section 8 and Section 16 of this
                      Agreement.

                      As to any deliveries made by the Bank pursuant to this
                      Section 6.12, securities or cash receivable in exchange
                      therefor shall be delivered to the Bank.

7. Redemptions. In the case of payment of assets of the Fund held by the Bank in
connection with redemptions and repurchases by the Fund of outstanding common
shares, the Bank will rely on notification by the Fund's transfer agent of

for redemption before such payment is made. Payment shall be made in accordance
with the Articles of Incorporation or Declaration of Trust and By-laws of the
Fund (the "Articles"), from assets available for said purpose.

distribution on Portfolio Securities as a result of a stock dividend, share
split-up, reorganization, recapitalization, merger, consolidation, readjustment,

9.4 Execute as agent on behalf of the Fund all necessary ownership and other

notify the Fund in writing of any default or refusal to pay within two business
days from the day on which it receives knowledge of such default or refusal.

12.  Fund Evaluation and Yield Calculation

12.1 Fund Evaluation. The Bank shall compute and, unless otherwise directed by
the Board, determine as of the close of regular trading on the New York Stock
Exchange on each day on which said Exchange is open for unrestricted trading and
as of such other days, or hours, if any, as may be authorized by the Board, the
net asset value and the public offering price of a share of capital stock of the
Fund, such determination to be made in accordance with the provisions of the
Articles and By-laws of the Fund and the Prospectus and Statement of Additional
Information relating to the Fund, as they may from time to time be amended, and
any applicable resolutions of the Board at the time in force and applicable; and
promptly to notify the Fund, the proper exchange and the NASD or such other
persons as the Fund may request of the results of such computation and
determination. In computing the net asset value hereunder, the Bank may rely in
good faith upon information furnished to it by any Authorized Person in respect
of (i) the manner of accrual of the liabilities of the Fund and in respect of
liabilities of the Fund not appearing on its books of account kept by the Bank,
(ii) reserves, if any, authorized by the Board or that no such reserves have
been authorized, (iii) the source of the quotations to be used in computing the
net asset value, (iv) the value to be assigned to any security for which no
price quotations are available, and (v) the method of computation of the public
offering price on the basis of the net asset value of the shares, and the Bank
shall not be responsible for any loss occasioned by such reliance or for any
good faith reliance on any quotations received from a source pursuant to (iii)
above.

12.2. Yield Calculation. The Bank will compute the performance results of the
Fund (the "Yield Calculation") in accordance with the provisions of Release No.
33-6753 and Release No. IC-16245 (February 2, 1988) (the "Releases") promulgated
by the Securities and Exchange Commission, and any subsequent amendments to,
published interpretations of or general conventions accepted by the staff of the
Securities and Exchange Commission with respect to such releases or the subject
matter thereof ("Subsequent Staff Positions"), subject to the terms set forth
below:

                      (a) The Bank shall compute the Yield Calculation for the
                      Fund for the stated periods of time as shall be mutually
                      agreed upon, and communicate in a timely manner the result
                      of such computation to the Fund.

                      (b) In performing the Yield Calculation, the Bank will
                      derive the items of data necessary for the computation
                      from the records it generates and maintains for the Fund
                      pursuant Section 11 hereof. The Bank shall have no
                      responsibility to review, confirm, or otherwise assume any
                      duty or liability with respect to the accuracy or
                      correctness of any such data supplied to it by the Fund,
                      any of the Fund's designated agents or any of the Fund's
                      designated third party providers.

                      (c) At the request of the Bank, the Fund shall provide,
                      and the Bank shall be entitled to rely on, written
                      standards and guidelines to be followed by the Bank in
                      interpreting and applying the computation methods set
                      forth in the Releases or any Subsequent Staff Positions as
                      they specifically apply to the Fund. In the event that the
                      computation methods in the Releases or the Subsequent
                      Staff Positions or the application to the Fund of a
                      standard or guideline is not free from doubt or in the
                      event there is any question of interpretation as to the
                      characterization of a particular security or any aspect of
                      a security or a payment with respect thereto (e.g.,
                      original issue discount, participating debt security,
                      income or return of capital, etc.) or otherwise or as to
                      any other element of the computation which is pertinent to
                      the Fund, the Fund or its designated agent shall have the
                      full responsibility for making the determination of how
                      the security or payment is to be treated for purposes of
                      the computation and how the computation is to be made and
                      shall inform the Bank thereof on a timely basis. The Bank
                      shall have no responsibility to make independent
                      determinations with respect to any item which is covered
                      by this

                                       14


<PAGE>



                     Section, and shall not be responsible for its computations
                     made in accordance with such determinations so long as such
                     computations are mathematically correct.

                      (d) The Fund shall keep the Bank informed of all publicly
                      available information and of any non-public advice, or
                      information obtained by the Fund from its independent
                      auditors or by its personnel or the personnel of its
                      investment adviser, or Subsequent Staff Positions related
                      to the computations to be undertaken by the Bank pursuant
                      to this Agreement and the Bank shall not be deemed to have
                      knowledge of such information (except as contained in the
                      Releases) unless it has been furnished to the Bank in
                      writing.

13. Additional Services. The Bank shall perform the additional services for the
Fund as are set forth on Appendix C hereto. Appendix C may be amended from time
to time upon agreement of the parties to include further additional services to
be provided by the Bank to the Fund, at which time the fees set forth in
Appendix A shall be appropriately increased.

                      (d) the legality of the repurchase of any common shares of

                      Moreover, the Bank will not be under any duty or
                      obligation to ascertain whether any Portfolio Securities
                      at any time delivered to or held by it for the account of
                      the Fund are such as may properly be held by the Fund
                      under the provisions of its Articles, By-laws, any federal
                      or state statutes or any rule or regulation of any
                      governmental agency.

14.2 Agents and Subcustodians with Respect to Property of the Fund Held in the
United States. The Bank may employ agents in the performance of its duties
hereunder and shall be responsible for the acts and omissions of such agents as
if performed by the Bank hereunder. Without limiting the foregoing, certain
duties of the Bank hereunder may be performed by one or more affiliates of the
Bank.

Upon receipt of Proper Instructions, the Bank may employ subcustodians, provided

                      authorizes and instructs the Bank to employ as

                      depositories designated on the Schedule attached hereto
                      (each, a "Selected Foreign Sub-Custodian"). Upon receipt
                      of Proper Instructions, together with a certified
                      resolution of the Fund's Board of Trustees, the Bank and
                      the Fund may agree to designate additional foreign banking
                      institutions and foreign securities depositories to act as
                      Selected Foreign Sub-Custodians hereunder. Upon receipt of
                      Proper Instructions, the Fund may instruct the Bank to
                      cease the employment of any one or more such Selected
                      Foreign Sub-Custodians for maintaining custody of the
                      Fund's assets, and the Bank shall so cease to employ such
                      sub-custodian as soon as alternate custodial arrangements
                      have been implemented.

                      (b) Foreign Securities Depositories. Except as may
                      otherwise be agreed upon in writing by the Bank and the
                      Fund, assets of the Fund shall be maintained in foreign
                      securities depositories only through arrangements
                      implemented by the foreign banking institutions serving as
                      Selected Foreign Sub-Custodians pursuant to the terms
                      hereof. Where possible, such arrangements shall include
                      entry into agreements containing the provisions set forth
                      in subparagraph (d) hereof. Notwithstanding the foregoing,
                      except as may otherwise be agreed upon in writing by the
                      Bank and the Fund, the Fund authorizes the deposit in
                      Euro-clear, the securities clearance and depository
                      facilities operated by Morgan Guaranty Trust Company of
                      New York in Brussels, Belgium, of Foreign Portfolio
                      Securities eligible for deposit therein and the use of
                      Euro-clear in connection with settlements of purchases and
                      sales of securities and deliveries and returns of
                      securities, until notified to the contrary pursuant to
                      subparagraph (a) hereunder.

                      (c) Segregation of Securities. The Bank shall identify on
                      its books as belonging to the Fund the Foreign Portfolio
                      Securities held by each Selected Foreign Sub-Custodian.
                      Each agreement pursuant to which the Bank employs a
                      foreign banking institution shall require that such
                      institution establish a custody account for the Bank and
                      hold in that account Foreign Portfolio Securities and
                      other assets of the Fund, and, in the event that such
                      institution deposits Foreign Portfolio Securities in a
                      foreign securities depository, that it shall identify on
                      its books as belonging to the Bank the securities so
                      deposited.

                      (d) Agreements with Foreign Banking Institutions. Each of
                      the agreements pursuant to which a foreign banking
                      institution holds assets of the Fund (each, a "Foreign
                      Sub-Custodian

                      Agreement") shall be substantially in the form attached as
                      Appendix D hereto and shall provide that: (a) the Fund's
                      assets will not be subject to any right, charge, security
                      interest, lien or claim of any kind in favor of the
                      foreign banking institution or its creditors or agent,
                      except a claim of payment for their safe custody or
                      administration (including, without limitation, any fees or
                      taxes payable upon transfers or reregistration of
                      securities); (b) beneficial ownership of the Fund's assets
                      will be freely transferable without the payment of money
                      or value other than for custody or administration
                      (including, without limitation, any fees or taxes payable
                      upon transfers or reregistration of securities); (c)
                      adequate records will be maintained identifying the assets
                      as belonging to the Bank; (d) officers of or auditors
                      employed by, or other representatives of the Bank,
                      including to the extent permitted under applicable law,
                      the independent public accountants for the Fund, will be
                      given access to the books and records of the foreign
                      banking institution relating to its actions under its
                      agreement with the Bank; and (e) assets of the Fund held
                      by the Selected Foreign Sub-Custodian will be subject only
                      to the instructions of the Bank or its agents.

                      (e) Access of Independent Accountants of the Fund. Upon
                      request of the Fund, the Bank will use its best efforts to
                      arrange for the independent accountants of the Fund to be
                      afforded access to the books and records of any foreign
                      banking institution employed as a Selected Foreign
                      Sub-Custodian insofar as such books and records relate to
                      the performance of such foreign banking institution under
                      its Foreign Sub-Custodian Agreement.

                      (f) Reports by Bank. The Bank will supply to the Fund from
                      time to time, as mutually agreed upon, statements in
                      respect of the securities and other assets of the Fund
                      held by Selected Foreign Sub-Custodians, including but not
                      limited to an identification of entities having possession
                      of the Foreign Portfolio Securities and other assets of
                      the Fund.

                      (g) Transactions in Foreign Custody Account. Transactions
                      with respect to the assets of the Fund held by a Selected
                      Foreign Sub-Custodian shall be effected pursuant to Proper
                      Instructions from the Fund to the Bank and shall be
                      effected in accordance with the applicable Foreign
                      Sub-Custodian Agreement. If at any time any Foreign
                      Portfolio Securities shall be registered in the name of
                      the nominee of the Selected Foreign Sub-Custodian, the
                      Fund agrees to hold any such nominee harmless from any
                      liability by reason of the registration of such securities
                      in the name of such nominee.

                      Notwithstanding any provision of this Agreement to the
                      contrary, settlement and payment for Foreign Portfolio
                      Securities received for the account of the Fund and
                      delivery of Foreign Portfolio Securities maintained for
                      the account of the Fund may be effected in accordance with
                      the customary established securities trading or securities
                      processing practices and procedures in the jurisdiction or
                      market in which the transaction occurs, including, without
                      limitation, delivering securities to the purchaser thereof
                      or to a dealer therefor (or an agent for such purchaser or
                      dealer) against a receipt with the expectation of
                      receiving later payment for such securities from such
                      purchaser or dealer.

                      In connection with any action to be taken with respect to
                      the Foreign Portfolio Securities held hereunder,
                      including, without limitation, the exercise of any voting
                      rights, subscription rights, redemption rights, exchange
                      rights, conversion rights or tender rights, or any other
                      action in connection with any other right, interest or
                      privilege with respect to such Securities (collectively,
                      the "Rights"), the Bank shall promptly transmit to the
                      Fund such information in connection therewith as is made
                      available to the Bank by the Foreign Sub-Custodian, and
                      shall promptly forward to the applicable Foreign
                      Sub-Custodian any instructions, forms or certifications
                      with respect to such Rights, and any instructions relating
                      to the actions to be taken in connection therewith, as the
                      Bank shall receive from the Fund pursuant to Proper
                      Instructions. Notwithstanding the foregoing, the Bank
                      shall have no further duty or obligation with respect to
                      such Rights, including, without limitation, the
                      determination of

                                       17
<PAGE>



                     whether the Fund is entitled to participate in such Rights
                     under applicable U.S. and foreign laws, or the
                     determination of whether any action proposed to be taken
                     with respect to such Rights by the Fund or by the
                     applicable Foreign Sub-Custodian will comply with all
                     applicable terms and conditions of any such Rights or any
                     applicable laws or regulations, or market practices within
                     the market in which such action is to be taken or omitted.

                      (h) Liability of Selected Foreign Sub-Custodians. Each
                      Foreign Sub-Custodian Agreement with a foreign banking
                      institution shall require the institution to exercise
                      reasonable care in the performance of its duties and to
                      indemnify, and hold harmless, the Bank and each Fund from
                      and against certain losses, damages, costs, expenses,
                      liabilities or claims arising out of or in connection with
                      the institution's performance of such obligations, all as
                      set forth in the applicable Foreign Sub-Custodian
                      Agreement. The Fund acknowledges that the Bank, as a
                      participant in Euro-clear, is subject to the Terms and
                      Conditions Governing the Euro-Clear System, a copy of
                      which has been made available to the Fund. The Fund
                      acknowledges that pursuant to such Terms and Conditions,
                      Morgan Guaranty Brussels shall have the sole right to
                      exercise or assert any and all rights or claims in respect
                      of actions or omissions of, or the bankruptcy or
                      insolvency of, any other depository, clearance system or
                      custodian utilized by Euro-clear in connection with the
                      Fund's securities and other assets.

                      (i) Monitoring Responsibilities. The Bank shall furnish
                      annually to the Fund information concerning the Selected
                      Foreign Sub-Custodians employed hereunder for use by the
                      Fund in evaluating such Selected Foreign Sub-Custodians to
                      ensure compliance with the requirements of Rule 17f-5 of
                      the Act. In addition, the Bank will promptly inform the
                      Fund in the event that the Bank is notified by a Selected
                      Foreign Sub-Custodian that there appears to be a
                      substantial likelihood that its shareholders' equity will
                      decline below US$200 million (or the equivalent thereof)
                      or that its shareholders' equity has declined below US$200
                      million (in each case computed in accordance with
                      generally accepted U.S. accounting principles) or any
                      other capital adequacy test applicable to it by exemptive
                      order, or if the Bank has actual knowledge of any material
                      loss of the assets of the Fund held by a Foreign
                      Sub-Custodian.

                      (j) Tax Law. The Bank shall have no responsibility or
                      liability for any obligations now or hereafter imposed on
                      the Fund or the Bank as custodian of the Fund by the tax
                      laws of any jurisdiction, and it shall be the
                      responsibility of the Fund to notify the Bank of the
                      obligations imposed on the Fund or the Bank as the
                      custodian of the Fund by the tax law of any non-U.S.
                      jurisdiction, including responsibility for withholding and
                      other taxes, assessments or other governmental charges,
                      certifications and governmental reporting. The sole
                      responsibility of the Selected Foreign Sub-custodian with
                      regard to such tax law shall be to use reasonable efforts
                      to assist the Fund with respect to any claim for exemption
                      or refund under the tax law of jurisdictions for which the
                      Fund has provided such information.

14.4 Insurance. The Bank shall use the same care with respect to the safekeeping
of Portfolio Securities and cash of the Fund held by it as it uses in respect of
its own similar property but it need not maintain any special insurance for the
benefit of the Fund.

14.5. Fees and Expenses of the Bank. The Fund will pay or reimburse the Bank
from time to time for any transfer taxes payable upon transfer of Portfolio
Securities made hereunder, and for all necessary proper disbursements, expenses
and charges made or incurred by the Bank in the performance of this Agreement
(including any duties listed on any Schedule hereto, if any) including any
indemnities for any loss, liabilities or expense to the Bank as provided above.
For the services rendered by the Bank hereunder, the Fund will pay to the Bank
such compensation or fees at such rate and at such times as shall be agreed upon
in writing by the parties from time to time. The Bank will also be entitled to

                                       18


<PAGE>



reimbursement by the Fund for all reasonable expenses incurred in conjunction
with termination of this Agreement.

14.6 Advances by the Bank. The Bank may, in its sole discretion, advance funds
on behalf of the Fund to make any payment permitted by this Agreement upon
receipt of any proper authorization required by this Agreement for such payments
by the Fund. Should such a payment or payments, with advanced funds, result in
an overdraft (due to insufficiencies of the Fund's account with the Bank, or for
any other reason) this Agreement deems any such overdraft or related
indebtedness a loan made by the Bank to the Fund payable on demand. Such
overdraft shall bear interest at the current rate charged by the Bank for such
loans unless the Fund shall provide the Bank with agreed upon compensating
balances. The Fund agrees that the Bank shall have a continuing lien and
security interest to the extent of any overdraft or indebtedness, in and to any
property at any time held by it for the Fund's benefit or in which the Fund has
an interest and which is then in the Bank's possession or control (or in the
possession or control of any third party acting on the Bank's behalf). The Fund
authorizes the Bank, in the Bank's sole discretion, at any time to charge any
overdraft or indebtedness, together with interest due thereon, against any
balance of account standing to the credit of the Fund on the Bank's books.

15. Limitation of Liability.

15.1 Notwithstanding anything in this Agreement to the contrary, in no event
shall the Bank or any of its officers, directors, employees or agents
(collectively, the "Indemnified Parties") be liable to the Fund or any third
party, and the Fund shall indemnify and hold the Bank and the Indemnified
Parties harmless from and against any and all loss, damage, liability, actions,
suits, claims, costs and expenses, including legal fees, (a "Claim") arising as
a result of any act or omission of the Bank or any Indemnified Party under this
Agreement, except for any Claim resulting solely from the negligence, willful
misfeasance or bad faith of the Bank or any Indemnified Party. Without limiting
the foregoing, neither the Bank nor the Indemnified Parties shall be liable for,
and the Bank and the Indemnified Parties shall be indemnified against, any Claim
arising as a result of:

                      (a) Any act or omission by the Bank or any Indemnified
                      Party in good faith reliance upon the terms of this

                      believed by the Bank to genuine;

                      (b) Any act or omission of any subcustodian selected by or
                      at the direction of the Fund;

                      (c) Any act or omission of a Selected Foreign
                      Sub-Custodian to the extent which such Selected Foreign
                      Sub-Custodian is not liable to the Bank;

                      (d) Any Corporate Action requiring a Response for which
                      the Bank has not received Proper Instructions or obtained
                      actual possession of all necessary Securities, consents or
                      other materials by 5:00 p.m. on the date specified as the
                      Response Deadline;

                      (e) Any act or omission of any European Branch of a U.S.
                      banking institution that is the issuer of Eurodollar CDs
                      in connection with any Eurodollar CDs held by such
                      European Branch;

                      (f) Information relied on in good faith by the Bank and
                      supplied by any Authorized Person in connection with the
                      calculation of (i) the net asset value and public offering
                      price of the shares of capital stock of the Fund or (ii)
                      the Yield Calculation; or

                      unavailability of energy sources and other similar
                      happenings or events.

15.2 Notwithstanding anything to the contrary in this Agreement, in no event
shall the Bank or the Indemnified Parties be liable to the Fund or any third
party for lost profits or lost revenues or any special, consequential, punitive
or incidental damages of any kind whatsoever in connection with this Agreement
or any activities hereunder.

16. Termination.

16.1 The term of this Agreement shall be three years commencing upon ______ (the
"Initial Term"), unless earlier terminated as provided herein. After the
expiration of the Initial Term, the term of this Agreement shall automatically
renew for successive one-year terms (each a "Renewal Term") unless notice of
non-renewal is delivered by the non-renewing party to the other party no later
than sixty days prior to the expiration of the Initial Term or any Renewal Term,
as the case may be.

                      (a) Either party hereto may terminate this Agreement prior
                      to the expiration of the Initial Term in the event the
                      other party violates any material provision of this
                      Agreement, provided that the non-violating party gives
                      written notice of such violation to the violating party
                      and the violating party does not cure such violation
                      within 90 days of receipt of such notice.

                      (b) Either party may terminate this Agreement during any
                      Renewal Term upon sixty days written notice to the other
                      party. Any termination pursuant to this paragraph 16.1(b)
                      shall be effective upon expiration of such sixty days,
                      provided, however, that the effective date of such
                      termination may be postponed to a date not more than
                      ninety days after delivery of the written notice: (i) at
                      the request of the Bank, in order to prepare for the
                      transfer by the Bank of all of the assets of the Fund held
                      hereunder; or (ii) at the request of the Fund, in order to
                      give the Fund an opportunity to make suitable arrangements
                      for a successor custodian.

16.2 In the event of the termination of this Agreement, the Bank will
immediately upon receipt or transmittal, as the case may be, of notice of
termination, commence and prosecute diligently to completion the transfer of all
cash and the delivery of all Portfolio Securities duly endorsed and all records
maintained under Section 11 to the successor custodian when appointed by the
Fund. The obligation of the Bank to deliver and transfer over the assets of the
Fund held by it directly to such successor custodian will commence as soon as
such successor is appointed and will continue until completed as aforesaid. If
the Fund does not select a successor custodian within ninety (90) days from the
date of delivery of notice of termination the Bank may, subject to the
provisions of subsection (16.3), deliver the Portfolio Securities and cash of
the Fund held by the Bank to a bank or trust company of the Bank's own selection
which meets the requirements of Section 17(f)(1) of the 1940 Act and has a
reported capital, surplus and undivided profits aggregating not less than
$2,000,000, to be held as the property of the Fund under terms similar to those
on which they were held by the Bank, whereupon such bank or trust company so
selected by the Bank will become the successor custodian of such assets of the
Fund with the same effect as though selected by the Board. Thereafter, the Bank
shall be released from any and all obligations under this Agreement.

                                       20


<PAGE>



16.3 Prior to the expiration of ninety (90) days after notice of termination has
been given, the Fund may furnish the Bank with an order of the Fund advising
that a successor custodian cannot be found willing and able to act upon
reasonable and customary terms and that there has been submitted to the
shareholders of the Fund the question of whether the Fund will be liquidated or
will function without a custodian for the assets of the Fund held by the Bank.
In that event the Bank will deliver the Portfolio Securities and cash of the
Fund held by it, subject as aforesaid, in accordance with one of such
alternatives which may be approved by the requisite vote of shareholders, upon
receipt by the Bank of a copy of the minutes of the meeting of shareholders at
which action was taken, certified by the Fund's Secretary and an opinion of
counsel to the Fund in form and content satisfactory to the Bank. Thereafter,
the Bank shall be released from any and all obligations under this Agreement.

16.4 The Fund shall reimburse the Bank for any reasonable expenses incurred by
the Bank in connection with the termination of this Agreement.

16.5 At any time after the termination of this Agreement, the Fund may, upon
written request, have reasonable access to the records of the Bank relating to
its performance of its duties as custodian.

17. Confidentiality. Both parties hereto agree than any non-public information
obtained hereunder concerning the other party is confidential and may not be
disclosed without the consent of the other party, except as may be required by
applicable law or at the request of a governmental agency. The parties further
agree that a breach of this provision would irreparably damage the other party
and accordingly agree that each of them is entitled, in addition to all other
remedies at low or in equal to an injunction or injunctions without bond or
other security to prevent breaches of this provision.

18. Notices. Any notice or other instrument in writing authorized or required by
this Agreement to be given to either party hereto will be sufficiently given if

registered mail, (ii) telecopier with written confirmation, (iii) had delivery

20. Parties. This Agreement will be binding upon and shall inure to the benefit
of the parties hereto and their respective successors and assigns; provided,
however, that this Agreement will not be assignable by the Fund without the
written consent of the Bank or by the Bank without the written consent of the
Fund, authorized and approved by its Board; and provided further that
termination proceedings pursuant to Section 16 hereof will not be deemed to be
an assignment within the meaning of this provision.

21. Governing Law. This Agreement and all performance hereunder will be governed
by the laws of the Commonwealth of Massachusetts, without regard to conflict of
laws provisions.

22. Counterparts. This Agreement may be executed in any number of counterparts,
each of which shall be deemed to be an original, but such counterparts shall,
together, constitute only one instrument.

23. Entire Agreement. This Agreement, together with its Appendices, constitutes
the sole and entire agreement between the parties relating to the subject matter
herein and does not operate as an acceptance of any conflicting terms or
provisions of any other instrument and terminates and supersedes any and all
prior agreements and undertakings between the parties relating to the subject
matter herein.

24. Limitation of Liability. The Bank is hereby expressly put on notice of the
limitation of liability set forth in the Master Trust Agreement of the Fund and
agrees that the obligations assumed by the Fund hereunder shall be limited in
all cases to the assets of the Fund and that the Bank shall not seek
satisfaction of any such obligation from the officers, agents, employees,
trustees, or shareholders of the Fund.

25. Several Obligations of the Portfolios. This Agreement is an agreement
entered into between the Bank and the Fund with respect to each Portfolio. With
respect to any obligation of the Fund on behalf of any Portfolio arising out of
this Agreement, the Bank shall look for payment or satisfaction of such
obligation solely to the assets of the Portfolio to which such obligation
relates as though the Bank had separately contracted with the Fund by separate
written instrument with respect to each Portfolio.

and cannot be held liable for any problem relating to such investments.

4. Duties of the Fund.

                      (a) The Fund is solely responsible (through its transfer
                      agent or otherwise) for (i) providing timely and accurate
                      reports ("Daily Sales Reports") which will enable IBT as
                      Administrator to monitor the total number of shares sold
                      in each state on a daily basis and (ii) identifying any
                      exempt transactions ("Exempt Transactions") which are to
                      be excluded from the Daily Sales Reports.

                      (b) The Fund agrees to make its legal counsel available to
                      IBT for instruction with respect to any matter of law
                      arising in connection with IBT's duties hereunder, and the
                      Fund further agrees that IBT shall be entitled to rely on
                      such instruction without further investigation on the part
                      of IBT.

5. Fees and Expenses.

                      (a) For the services to be rendered and the facilities to
                      be furnished by IBT, as provided for in this Agreement,
                      the Fund will compensate IBT in accordance with the fee
                      schedule attached as Appendix 2 hereto. Such fees do not
                      include out-of-pocket disbursements (as delineated on the
                      fee schedule or other expenses with the prior approval of
                      the Fund's management) of IBT for which IBT shall be
                      entitled to bill the Fund separately and for which the
                      Fund shall reimburse IBT.

                      (b) IBT shall not be required to pay any expenses incurred
                      by the Fund.

6. Limitation of Liability.

                      (a) IBT, its directors, officers, employees and agents
                      shall not be liable for any error of judgment or mistake
                      of law or for any loss suffered by the Fund in connection
                      with the performance of its obligations and duties under
                      this Agreement, except a loss resulting from willful
                      misfeasance, bad faith or negligence in the performance of
                      such obligations and duties, or by reason of its reckless
                      disregard thereof. The Fund will indemnify IBT, its
                      directors, officers, employees and agents against and hold
                      it and them harmless from any and all losses, claims,
                      damages, liabilities or expenses (including legal fees and
                      expenses) resulting from any claim, demand, action or suit
                      (i) arising out of the actions or omissions of the Fund,
                      including, but not limited to, inaccurate Daily Sales
                      Reports and misidentification of Exempt Transactions; (ii)
                      arising out of the offer or sale of any securities of the
                      Fund in violation of (x) any requirement under the federal
                      securities laws or regulations, (y) any requirement under
                      the securities laws or regulations of any state, or (z)
                      any stop order or other determination or ruling by any
                      federal or state agency with respect to the offer or sale
                      of such securities; or (iii) not resulting from the
                      willful misfeasance, bad faith or negligence of IBT in the
                      performance of such obligations and duties or by reason of
                      its reckless disregard thereof.

                      (b) IBT may apply to the Fund at any time for instructions
                      and may consult counsel for the Fund, or its own counsel,
                      and with accountants and other experts with respect to any
                      matter arising in connection with its duties hereunder,
                      and IBT shall not be liable or accountable for any action
                      taken or omitted by it in good faith in accordance with
                      such instruction, or with the opinion of such counsel,
                      accountants, or other experts. IBT shall not be liable for
                      any act or omission taken or not taken in reliance upon
                      any document, certificate or instrument which it
                      reasonably believes to be genuine and to be signed or
                      presented by the proper person or persons. IBT shall not
                      be held to have notice of any change of authority of any
                      officers, employees, or agents of the Fund until receipt
                      of written notice thereof has been received by IBT from
                      the Fund.

                      (c) In the event IBT is unable to perform, or is delayed
                      in performing, its obligations under the terms of this
                      Agreement because of acts of God, strikes, legal
                      constraint, government actions, war, emergency conditions,
                      interruption of electrical power or other utilities,
                      equipment or transmission failure or damage reasonably
                      beyond its control or other causes reasonably beyond its
                      control, IBT shall not be liable to the Fund for any
                      damages resulting from such failure to perform, delay in
                      performance, or otherwise from such causes.

                      (d) In no event shall IBT be liable for special,
                      incidental or consequential damages, even if advised of
                      the possibility of such damages.

7. Termination of Agreement.

                      (a) The term of this Agreement shall be three years
                      commencing upon the date hereof (the "Initial Term"),
                      unless earlier terminated as provided herein. After the
                      expiration of the Initial Term, the term of this Agreement
                      shall automatically renew for successive one-year terms
                      (each a "Renewal Term") unless notice of non-renewal is
                      delivered by the non-renewing party to the other party no
                      later than sixty days prior to the expiration of the
                      Initial Term or any Renewal Term, as the case may be.

                              (i) Either party hereto may terminate this
                              Agreement prior to the expiration of the Initial
                              Term in the event the other party violates any
                              material provision of this Agreement, provided
                              that the violating party does not cure such
                              violation within 90 days of receipt of written
                              notice from the non-violating party of such
                              violation.

                              (ii) Either party may terminate this Agreement
                              during any Renewal Term upon sixty days written
                              notice to the other party. Any termination
                              pursuant to this paragraph 7(a)(ii) shall be
                              effective upon expiration of such sixty days,
                              provided, however, that the effective date of such
                              termination may be postponed, at the request of
                              the Fund, to a date not more than ninety days
                              after delivery of the written notice in order to
                              give the Fund an opportunity to make suitable
                              arrangements for a successor administrator.

                      (b) At any time after the termination of this Agreement,
                      the Fund may, upon written request, have reasonable access
                      to the records of IBT relating to its performance of its
                      duties as Administrator.

8. Miscellaneous.

                      (a) Any notice or other instrument authorized or required
                      by this Agreement to be given in writing to the Fund or
                      IBT shall be sufficiently given if addressed to that party
                      and received by it at its office set forth below or at
                      such other place as it may from time to time designate in
                      writing.

                      upon the parties hereto and their respective successors
                      and assigns; provided, however, that this Agreement shall
                      not be assignable without the written consent of the other
                      party.

                      (c) This Agreement shall be construed in accordance with

                      (d) This Agreement may be executed in any number of
                      counterparts each of which shall be deemed to be an

                      convenience of reference only and in no way define or

judicial authority; provided further, that in no event shall such approval be
unreasonably withheld or delayed.

any such obligation from the officers, agents, employees, trustees, or

entered into between IBT and the Fund with respect to each Portfolio. With
respect to any obligation of the Fund on behalf of any Portfolio arising out of

IBT had separately contracted with the Fund by separate written instrument with

Merrimac Series
200 Clarendon Street
Boston, Massachusetts 02116

Ladies and Gentlemen:

         As counsel to Merrimac Series (the "Trust"), a Delaware business trust,
we have been asked to render our opinion in connection with the proposed
issuance of an indefinite number of Premium Class, Institutional Class and
Investment Class shares of beneficial interest, all with $0.001 par value, of
the Trust (the "Shares") representing interests in the Merrimac Treasury Plus
Series, as more fully described in the Prospectus and Statement of Additional
Information contained in Post-Effective Amendment No. 1 (the "Amendment") to the
Trust's Registration Statement on Form N-1A (Registration No. 333-49693) to be
filed by the Trust with the Securities and Exchange Commission.

         We have examined the Master Trust Agreement dated as of March 30, 1998,
as amended, the By-Laws of the Trust, the minutes of certain meetings of the
Trustees, the Prospectus and Statement of Additional Information contained in
the Amendment, and such other documents, records and certificates as we have
deemed necessary for the purposes of this opinion.

         Based upon the foregoing, we are of the opinion that the Shares, when
sold in accordance with the terms of the Prospectus and Statement of Additional
Information in effect at the time of sale, will be legally issued, fully paid
and non-assessable by the Trust.

         We hereby consent to the filing of this opinion as an exhibit to the
Amendment and to the reference to this firm as legal counsel for the Trust in
the Prospectus and Statement of Additional Information contained in the
Amendment.

                                              Very truly yours,

                                              /s/ GOODWIN, PROCTER & HOAR  LLP
