                              RISK/RETURN SUMMARIES

The following  information is only a summary of important  information that you
should know about each series of Merrimac  Series (the  Funds).  More  detailed
information  is included  elsewhere in this  Prospectus and in the Statement of
Additional Information (SAI) and should be read in addition to this summary. As
with any mutual fund,  there is no guarantee  that the Funds will achieve their
goals.

Traditional  mutual  funds  directly  acquire  and manage  their own  portfolio
securities. The Funds are organized in a "master-feeder" structure, under which
each Fund  invests  all of its  assets in a  corresponding  series of  Merrimac
Master Portfolio or Standish, Ayer & Wood Master Portfolio (each, a Portfolio).
Each  Fund  and  its  corresponding   Portfolio  have  substantially  the  same
investment objectives and investment policies.
 

MERRIMAC CASH SERIES


WHAT IS THE FUND'S INVESTMENT OBJECTIVE AND MAIN STRATEGY?

The Merrimac  Cash Series'  investment  objective is to achieve a high level of
current income  consistent with preserving  principal and liquidity.  Allmerica
Asset  Management,  Inc.  (AAM),  the  subadviser of Merrimac  Cash  Portfolio,
attempts to achieve the Fund's objective by investing the Portfolio's assets in
high-quality, U.S. dollar-denominated, money market instruments with maturities
of 397 calendar days or less.  Most of the Portfolio's  investments  will be in
U.S. Treasury bills, notes and bonds, other instruments issued or guaranteed by
the U.S.  Government or its  agencies,  securities of U.S. and foreign banks or
thrift  organizations,  corporate debt  obligations,  asset-backed  securities,
variable rate obligations and repurchase  agreements that are collateralized by
these instruments.

In view of the risks inherent in all  investments  in  securities,  there is no
assurance that the Fund's  objective will be achieved.  See FUNDS'  INVESTMENTS
for more information.

MAIN RISKS OF INVESTING IN THE FUND

The primary  risks in investing  in the Fund are interest  rate risk and credit
risk.

O  INTEREST RATE RISK involves the  possibility  that the value of the Fund's
   investments will decline due to an increase in interest rates.

O  CREDIT RISK involves the possibility that an issuer of a security owned by 
   the Fund has its credit rating downgraded or defaults on its obligation to
   pay principal and/or interest.

                                       3

<PAGE>

Money market funds can be confused  with  savings  accounts.  The Fund is not a
savings account but, rather, a money market mutual fund that issues and redeems
at the  Fund's  per share net  asset  value  (NAV).  The Fund  always  seeks to
maintain a constant NAV of $1.00 per share.

Unlike a savings account,  however,  an investment in the Fund is not a deposit
of Investors  Bank & Trust  Company,  or any other bank,  and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other government
agency.  Although  the Fund seeks to preserve the value of your  investment  at
$1.00 per share, it is possible to lose money by investing in the Fund.

IS THE FUND FOR YOU?

The Fund may be appropriate as part of your investment portfolio if......

O  You need your money back within a short period.
O  You need to preserve principal.
O  You want a low-risk investment.

The Fund may not be appropriate as part of your investment portfolio if......

O  You need a high total return to achieve your goals.
O  You seek long-term growth as your primary goal.

COULD THE VALUE OF YOUR INVESTMENT IN THE FUND FLUCTUATE?

Yes, it could.  The Fund is managed in accordance  with strict  Securities  and
Exchange  Commission  guidelines designed to preserve the Fund's value at $1.00
per share, although, of course, there cannot be a guarantee that the value will
remain at $1.00 per share.  The value of your  investment  typically  will grow
through reinvested dividends.

TOTAL RETURN

All mutual funds must use the same formula to calculate  total return.  The bar
chart and total return table  indicate the risks of investing in the Fund.  The
bar chart shows  changes in the  performance  of the Fund for the full calendar
periods indicated.  The total return table shows how the Fund's  average annual
returns for different calendar periods compared to those of a widely recognized
index of short-term Treasury securities and money market fund shares.

The Fund began  operations on June 25, 1998.  The total return shown is for the
Premium  Class of the Merrimac  Cash Fund which is a separate  feeder fund that
invests all of its assets in the Portfolio.  The total return of the Fund would
differ  from the  total  return  of  Merrimac  Cash  Fund to the  extent of any
differences in their respective operating expenses. During the periods shown in
the bar chart, the highest total return for a quarter was 1.42% (quarter ending
December 31, 1997) and the lowest total return for a quarter was 1.32% (quarter
ending March 31, 1997).

The  performance  information  should  be  considered  in light  of the  Fund's
investment  objective  and policies and market  conditions  during the reported
time periods.  Historical  performance does not necessarily  indicate what will
happen in the future.  For the Fund's most current  yield  information  you may
call 1-888-MERRMAC.

FEES AND EXPENSES

This summary  shows what it will cost you directly or  indirectly  to invest in
the Fund.

There are no fees or sales loads  charged to your  account when you buy or sell
Fund  shares.  However,  if you sell  shares  and  request  your  money by wire

ANNUAL FUND OPERATING EXPENSES - EXPENSES THAT ARE DEDUCTED FROM FUND ASSETS

Fund  expenses are  reflected in the Fund's share price and  dividends.  "Other

figures below show actual  expenses before waivers during the fiscal year ended
December  31,  1998 for the  PREMIUM and  INSTITUTIONAL  Classes and  estimated
expenses  for the  current  fiscal  year  for  the  INVESTMENT  Class,  and are
calculated as a percentage of average net assets.

   investments will decline due to an increase in interest rates.

O  CREDIT RISK involves the possibility that an issuer of a secured owned by 
   the Fund has its credit rating downgraded or defaults on its obligation to
   pay principal and/or interest.

Money market funds can be confused  with  savings  accounts.  The Fund is not a
savings account but, rather, a money market mutual fund that issues and redeems
at the  Fund's  net asset  value  (NAV) per  share.  The Fund  always  seeks to
maintain a constant NAV of $1.00 per share.

Unlike a savings account,  however,  an investment in the Fund is not a deposit
of Investors  Bank & Trust  Company,  or any other bank,  and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other government
agency.  Although  the Fund seeks to preserve the value of your  investment  at
$1.00 per share, it is possible to lose money by investing in the Fund.

IS THE FUND FOR YOU?

The Fund may be appropriate as part of your investment portfolio if......

O  You need your money back within a short period.
O  You need to preserve principal.
O  You want a low-risk investment.

The Fund may not be appropriate as part of your investment portfolio if......

O  You need a high total return to achieve your goals.
O  You seek long-term growth as your primary goal.

COULD THE VALUE OF YOUR INVESTMENT IN THE FUND FLUCTUATE?

Yes, it could.  The Fund is managed in accordance  with strict  Securities  and
Exchange  Commission  guidelines designed to preserve the Fund's value at $1.00
per share, although, of course, there cannot be a guarantee that the value will
remain at $1.00 per share.  The value of your  investment  typically  will grow
through reinvested dividends.

TOTAL RETURN

All mutual funds must use the same formula to calculate  total return.  The bar
chart and total return table  indicate the risks of investing in the Fund.  The
bar chart shows  changes in the  performance  of the Fund for the full calendar
period  indicated.  The total return table shows how the Fund's  average annual
returns for different calendar periods compared to those of a widely recognized
index of short term Treasury securities and money market fund shares.

MERRIMAC TREASURY PLUS SERIES



WHAT IS THE FUND'S INVESTMENT OBJECTIVE AND MAIN STRATEGY?

The Merrimac  Treasury Plus Series'  investment  objective is to achieve a high
level of current income consistent with preserving principal and liquidity. M&I
Investment  Management Corp.  (M&I),  the subadviser of Merrimac  Treasury Plus
Portfolio,   attempts  to  achieve  the  Fund's   objective  by  investing  the
Portfolio's  assets in  high-quality,  U.S.  dollar-denominated,  money  market
instruments  with  maturities of 397 calendar days or less.  The Portfolio will
invest  primarily (at least 65% of total assets) in direct  obligations  of the
U.S. Treasury,  such as U.S. Treasury bills, notes and bonds. The Portfolio may
invest the remaining 35% of its total assets in securities issued or guaranteed
by the U.S.  Government  or its  agencies.  The  Portfolio  also may  invest in
repurchase agreements that are collateralized by these instruments.

In view of the risks inherent in all  investments  in  securities,  there is no
assurance that the Fund's  objective will be achieved.  See FUNDS'  INVESTMENTS
for more information.

MAIN RISKS OF INVESTING IN THE FUND

The primary  risks in investing  in the Fund are interest  rate risk and credit
risk.

O  INTEREST RATE RISK involves the possibility that the value of the Fund's
   investments will decline due to an increase in interest rates.

O  CREDIT RISK involves the possibility that an issuer of a security owned by
   the Fund has its credit rating downgraded or defaults on its obligation to
   pay principal and/or interest.

Money market funds can be confused  with  savings  accounts.  The Fund is not a
savings account but, rather, a money market mutual fund that issues and redeems
at the  Fund's  net asset  value  (NAV) per  share.  The Fund  always  seeks to
maintain a constant NAV of $1.00 per share.

Unlike a savings account,  however,  an investment in the Fund is not a deposit
of Investors  Bank & Trust  Company,  or any other bank,  and is not insured or
guaranteed by the FDIC or any other government agency.  Although the Fund seeks
to preserve the value of your  investment  at $1.00 per share it is possible to
lose money by investing in the Fund.

MERRIMAC SHORT-TERM ASSET RESERVE (STAR) SERIES



WHAT IS THE FUND'S INVESTMENT OBJECTIVE AND MAIN STRATEGY?

The Merrimac  STAR Series'  investment  objective is to achieve a high level of
current income  consistent with preserving  principal and liquidity.  Standish,
Ayer & Wood, Inc. (Standish),  the adviser of Standish Short-Term Asset Reserve
Portfolio,   attempts  to  achieve  the  Fund's   objective  by  investing  the
Portfolio's   assets   primarily  in  U.S.   dollar-denominated   money  market
instruments,  short-term fixed income securities and asset-backed securities of
U.S. and foreign

                                       15

<PAGE>

governments,   banks  and  companies.  The  Portfolio  invests  exclusively  in
investment  grade securities and no more than 15% of total assets in securities
rated BBB or Baa (A-2, P-2 or Duff-2 for money market  instruments) by a rating
agency of their unrated equivalents. Standish targets an average credit quality
of the Portfolio's investment securities of AA/Aa. The Portfolio generally will
maintain an average  dollar-weighted  effective  portfolio  maturity of 6 to 15
months with a maximum  average  maturity of 18 months.  No security can have an
effective maturity of more than 5 years.

Standish  focuses  on  identifying   undervalued  sectors  and  securities  and
minimizes the use of an interest rate forecasting strategy.  Standish looks for
securities with the most potential for added value, such as those involving the
potential for credit upgrades, unique structural  characteristics or innovative
features. Standish selects securities for the Portfolio by:

     O  Allocating assets among sectors appearing to have near-term return
        potential.

     O  Actively trading among various sectors. such as corporate bonds, 
        mortgagae pass through securities, government agencies and asset-backed
        securities.

     O  Buying when a yield spread advantage presents an opportunity to buy
        securities cheaply.

     O  Using research to locate opportunities in less-efficient areas of the
        short-term fixed-income market.

     O  Using yield curve analysis to identify securities that present the most
        attractive tradeoff between the higher returns and higher risks
        associated with extending maturities.

     O  Investing in innovative securities that may  not be widely followed or
        understood by other investors.

In view of the risks inherent in all  investments  in  securities,  there is no
assurance that the Fund's  objective will be achieved.  See FUNDS'  INVESTMENTS
for more information.

MAIN RISKS OF INVESTING IN THE FUND

Investors  could lose money on their  investment in the Fund. The primary risks
of investing in the Fund are as follows:

O  INTEREST RATE RISK involves the possibility that the value of the Fund's
   investments will decline due to an increase in interest rates.

O  CREDIT RISK involves the possibility that an issuer of a security owned by
   the Fund has its credit rating downgraded or defaults on its obligation to
   pay principal and/or interest.

O  PREPAYMENT RISK involves the possibility that when interest rates are
   declining, the issuer of a security exercises its right to prepay principal
   earlier than scheduled, forcing the Fund to reinvest in lower yielding
   securities. 

O  EXTENSION RISK involves the possibility that when interest rates are rising,
   the average life of some securities may extend because of slower than
   expected principal payments.  This will lock in a below-market interest
   rate, increase the security's duration and reduce the value of the security.

                                       16

<PAGE>

O  FOREIGN SECURITIES RISK involves the possibility that prices of foreign
   securities may decline due to unfavorable foreign government actions,
   political, economic or market instability or the absence of accurate
   information about foreign companies.  Foreign securities are sometimes less
   liquid and harder to value than securities of U.S. issuers.

An investment in the Fund is not a deposit of Investors  Bank & Trust  Company,
or any other bank,  and is not  insured or  guaranteed  by the Federal  Deposit
Insurance Corporation or any other government agency.

IS THE FUND FOR YOU?

The Fund may be appropriate as part of your investment portfolio if......

O  You seek an alternative to a money market fund without the price stability
   of a money market fund.
O  You seek limited price fluctuation and current income.
O  You are looking to diversify a fixed-income portfolio with short-term
   investments.

The Fund may not be appropriate as part of your investment portfolio if......

O  You need a high total return to achieve your goals.
O  You seek long-term growth as your primary goal.

COULD THE VALUE OF YOUR INVESTMENT IN THE FUND FLUCTUATE?

Yes, it could.  Unlike a money market fund, the Fund is not managed to preserve
                                                        ---
the Fund's net asset value at $1.00 per share and  therefore  the Fund's  share
price will fluctuate.

TOTAL RETURN

All mutual funds must use the same formula to calculate  total return.  The bar
chart and total return table  indicate the risks of investing in the Fund.  The
bar chart shows  changes in the  performance  of the Fund for the full calendar
periods  indicated.  The total return table shows how the Fund's average annual
returns for different calendar periods compared to those of a widely recognized
index of short term Treasury securities and money market fund shares.

                             THE FUNDS' INVESTMENTS

MERRIMAC CASH SERIES

PRINCIPAL INVESTMENT STRATEGIES AND RISKS




Q  What is the Fund's principal investment strategy?

A  The Fund's principal investment strategy is to invest the Fund's share of
   the Portfolio's assets in U.S. dollar-denominated money market instruments
   with remaining maturities of 397 calendar days or less that in the opinion
   of AAM present minimal credit risk.

Q  Into what types of money market instruments will the Fund's assets be
   invested?

A  The Portfolio may invest in the following:

   O  obligations of the U.S. Government or its agencies or instrumentalities;
   O  corporate debt obligations such as notes, bonds, commercial paper and
      other money market instruments;
   O  variable rate obligations;
   O  securities of U.S. and foreign banks or thrift organizations (such as
      bankers' acceptances, time deposits and certificates of deposits);
   O  asset-backed securities; 
   O  other short-term debt securities; and
   O  repurchase agreements that are collateralized by the securities listed
      above.

   Further description of these securities is found in APPENDIX A.

Q  Are there any limits on how much that can be invested in one issuer?

A  Yes. The Securities and Exchange Commission (SEC) has set certain
   diversification requirements for money market funds. Generally, these
   requirements limit a money market fund's investments in securities of any
   issuer to no more than 5% of a fund's assets. Also, strict SEC guidelines
   do not permit AAM to invest, with respect to 75% of the Portfolio's assets,
   greater than 10% of the Portfolio's assets in securities issued by or
   subject to guarantees by the same institution. Purchases of securities
   issued or guaranteed by the U.S. Government or its agencies or
   instrumentalities are not counted toward these limitations.

                                      21

<PAGE>

Q  What is the credit quality of the Fund's investments?

A  The Portfolio's investments consist of high-quality securities that qualify
   as "first-tier" securities under the SEC rules that apply to money market
   funds.  In general, a first-tier security is defined as a security that is:

  O  issued or guaranteed by the U.S. Government or any agency or
     instrumentality thereof;
  O  rated or subject to a guarantee that is rated in the highest category for
     short-term securities by at least two Nationally Recognized Statistical
     Rating Organizations (NRSROs), or by one NRSRO if the security is rated by
     only one NRSRO;
  O  unrated but issued by an issuer or guaranteed by a guarantor that has
     other comparable short-term obligations so rated; or
  O  unrated but determined by AAM to be of comparable quality.

  In addition, AAM must consider whether a particular investment presents
  minimal credit risk.

Q  Who are the Nationally Recognized Statistical Rating Organizations?

A  Current NRSROs include:

   O  Moody's Investors Service, Inc.;
   O  Standard & Poor's Ratings Group;
   O  Fitch's IBCA Investors Service; 
   O  Duff & Phelps'; and
   O  Thomson Bank Watch.

Q  What happens if the rating of a security is downgraded?

A  If the rating of a security is downgraded after purchase, AAM will determine
   whether it is in the best interest of the Portfolio's shareholders (i.e.,
   the Fund) to continue to hold the security.

Q  Will the Fund always maintain a net asset value of $1 per share?

A  While AAM will endeavor to maintain a constant Fund NAV of $1 per share,
   there is no assurance that they will be able to do so.  The shares are
   neither insured nor guaranteed by the U.S. Government.  As such, the Fund
   carries some risk.   For example, there is always a risk that the issuer of
   a security held by the Portfolio will fail to pay interest or principal when
   due.  The Portfolio attempts to minimize credit risk by investing only in
   securities rated in the highest category for short-term securities, or, if
   not rated, of comparable quality, at the time of purchase.  Additionally,
   the Portfolio will not purchase a security unless AAM has determined that
   the security presents minimal credit risk. There is also a risk that rising
   interest rates will cause the value of the Portfolio's securities to
   decline.  The Portfolio attempts to minimize interest rate risk by limiting
   the maturity of each security to 397 calendar days or less and maintaining a
   dollar-weighted average portfolio maturity for the Portfolio of 90 days or
   less.

                                      22

<PAGE>

Q  How are the decisions to buy or sell securities made?

A  Factors are balanced such as credit quality and maturity to purchase the
   best relative value available in the market at any given time.  While rare,
   sell decisions are usually based on a change in credit analysis or to take
   advantage of an opportunity to reinvest at a higher yield.

PRINCIPAL INVESTMENT STRATEGIES AND RISKS


Q  What is the Fund's principal investment strategy?

A  The Fund's principal investment strategy is to invest the Fund's share of
   the Portfolio's assets in U.S. Treasury securities with maturities of 397
   calendar days or less.

Q  Into what types of money market instruments will the Fund's assets be
   invested?

A  The Portfolio may only invest in direct obligations of the U.S. Treasury,
   such as U.S. Treasury bills, notes and bonds or in other mutual funds that
   invest in such instruments.  To maximize tax-effective yield, the Portfolio
   will usually (but not always) invest in obligations that qualify for the
   exemption from state taxation.  Further description of these securities is
   found in APPENDIX A.

Q  Are there any limits on how much that can be invested in one issuer?

A  By the Fund's strategy, the U.S. Treasury is the only issuer in which the
   Portfolio invests.  If, for liquidity purposes, the Portfolio invests in 
   other mutual funds having the same principal investment strategy, its total
   investment in other mutual funds may not exceed 10% of assets and investment
   in a single fund may not exceed 5% of assets or 3% of that fund's total
   assets.

Q  Will the Fund always maintain a net asset value of $1 per share?

A  While M&I will endeavor to maintain a constant Fund NAV of $1 per share,
   there is no assurance that they will be able to do so. The shares are
   neither insured nor guaranteed by the U.S. Government. As such, the Fund
   carries some risk.   There is a risk that rising interest rates will cause
   the value of the Portfolio's securities to decline.  M&I attempts to
   minimize this risk by limiting the maturity of each security to 397 calendar
   days or less and maintaining a dollar-weighted average portfolio maturity
   for the Portfolio of 90 days or less.

Q  How are the decisions to buy or sell securities made?

A  Factors are balanced such as the Portfolio's objective of maximizing current
   income while maintaining safety and liquidity.  M&I evaluates the treasury
   securities market daily to determine how to provide the most value to the
   Portfolio.

Q  What is the Fund's principal investment strategy?

A  The Fund's principal investment strategy is to invest the Fund's share of
   the Portfolio's assets in high-quality, U.S. dollar-denominated Treasury
   securities with maturities of 397 calendar days or less.

Q  Into what types of money market instruments will the Fund's assets be
   invested?

A  The Portfolio will invest at least 65% of its total assets in direct
   obligations of the U.S. Treasury; such as U.S. Treasury bills, notes and
   bonds and may invest the remaining 35% of its total assets in securities
   issued or guaranteed by the U.S. Government or its agencies.  The Portfolio
   may also invest in repurchase agreements that are collateralized by these
   instruments.  Further description of these securities is found in APPENDIX 
   A.

Q  Are there any limits on how much that can be invested in one issuer?

A  No.  Beyond the percentages noted above, the Portfolio is not limited with
   respect to purchases of securities issued by the U.S. Government or its
   agencies.

Q  Will the Fund always maintain a net asset value of $1 per share?

A  While M&I will endeavor to maintain a constant Fund NAV of $1 per share,
   there is no assurance that they will be able to do so.  The shares are
   neither insured nor guaranteed by the U.S. Government.  As such, the Fund
   carries some risk.  There is a risk that rising interest rates will cause

   minimize interest rate risk by limiting the maturity of each security to 397
   calendar days or less and maintaining a dollar-weighted average portfolio
   maturity for the Portfolio of 90 days or less.

Q  How are the decisions to buy or sell securities made?

A  Factors are balanced such as the Portfolio's objective of maximizing current
   income while maintaining safety and liquidity.  M&I evaluates the government
   securities market compared to the repurchase agreement market to determine
   which provides the most value to the Portfolio.

   than 15% of assets in securities rated BBB or Baa (A-2, P-2 or Duff-2 for
   money market instruments) by a rating agency or their unrated equivalents.

   Securities are investment grade if they are:

   O  rated in one of the four highest long-term rating categories of a
      Nationally Recognized Statistical Rating Organization (NRSRO);
   O  have received a comparable short-term or other rating; or
   O  unrated but determined by Standish to be of comparable quality.

   If a security receives "split" (different) ratings from multiple NRSROs, the
   Portfolio will treat the security as being rated in the higher rating
   category.  The Portfolio's credit standards also apply to counterparties to
   OTC derivative contracts.

                                       25

<PAGE>

Q  Who are the Nationally Recognized Statistical Rating Organizations?

A  Current NRSROs include:

   O  Moody's Investors Service, Inc.;
   O  Standard & Poor's Ratings Group;
   O  Fitch's IBCA Investors Service; and
   O  Duff & Phelps.

Q  What happens if the rating of a security is downgraded?

A  If the rating of a security is downgraded after purchase, Standish may
   choose not to sell securities that are downgraded below the Portfolio's
   minimum acceptable credit rating after its purchase.

Q  May the Portfolio invest defensively?

A  Yes.  The Portfolio may depart from its principal investment strategy in
   response to adverse market, economic or political conditions by taking a
   temporary defensive position in all types of money market and short-term
   debt securities.  If the Portfolio takes a temporary defensive position, it
   may be unable for a time to achieve its investment objective.

Q  May the Portfolio use derivative contracts?

A  Yes.  The Portfolio may, but is not required to, use derivative contracts
   for any of the following purposes:

   O  To hedge against adverse changes - caused by changing interest rates - in
      the market value of securities held by or to be bought for the Portfolio.
   O  As a substitute for purchasing or selling securities.
   O  To shorten or lengthen the effective maturity or duration of the
      Portfolio's portfolio.
   O  To enhance the Portfolio's potential gain in non-hedging situations.

A  derivative  contract  will  obligate or entitle the  Portfolio to deliver or
receive  an asset or a cash  payment  that is based on the change in value of a
designated  security or index. Even a small investment in derivative  contracts
can have a big impact on a portfolio's interest rate exposure. Therefore, using
derivatives  can  disproportionately   increase  portfolio  losses  and  reduce
opportunities for gains when interest rates are changing. The Portfolio may not
fully benefit from or may lose money on  derivatives  if changes in their value
do not  correspond  accurately  to  changes  in the  value  of the  Portfolio's
holdings.

Counterparties  to OTC  derivative  contracts  present the same types of credit
risk as  issuers  of fixed  income  securities.  Derivatives  can also make the
Portfolio's portfolio less liquid and harder to value,  especially in declining
markets.
 
Q   What is the Portfolio's policy regarding portfolio turnover?

A   The  Portfolio may engage in active and frequent trading to achieve its
    principal investment strategies.  This may lead to the realization and
    distribution to shareholders of higher capital gains, which would increase
    their tax liability.  Frequent trading also increases transaction costs,
    which could detract from the Portfolio's performance.

The Fund's  investment  objective may be changed by the Fund's Trustees without
shareholder  approval.  For additional  information  about other  securities in
which the Portfolios invest their assets, see APPENDIX A.

                               FUNDS' MANAGEMENT

INVESTMENT ADVISER

The Funds have not retained the services of an investment  adviser because each
Fund invests all of its investable assets in its corresponding  Portfolio.  The
Cash  Portfolio,  Treasury  Portfolio and Treasury Plus Portfolio have retained
the services of Investors Bank & Trust Company  (Investors  Bank) as investment
adviser.  Investors Bank continuously reviews and supervises the Cash, Treasury

responsibilities subject to the supervision of, and policies established by the
Board of Trustees.  Investors Bank's business address is 200 Clarendon  Street,
Boston,  Massachusetts  02116.  Investors  Bank began  acting as an  investment
adviser at the  commencement of operations of the Cash Portfolio  (November 21,
1996). The Cash Portfolio,  Treasury Portfolio and Treasury Plus Portfolio each
pay Investors Bank a unitary fee for servicing  these  Portfolios as Investment
Adviser, Administrator,  Custodian, Fund Accountant and Transfer Agent. The fee
is  computed  at an annual rate of 0.17% of average net assets of each of these
Portfolios.

The STAR  Portfolio  has retained the services of Standish,  Ayer & Wood,  Inc.

Portfolio's Board of Trustees.  Standish has been providing investment advisory
services since it was established in 1933.  Standish's  business address is One
Financial Center,  Boston,  Massachusetts 02111. For its services as investment
adviser to the Portfolio,  Standish is paid fee by the STAR Portfolio, computed
at an annual  rate of 0.25% of the  average  net assets of the STAR  Portfolio,
including those attributable to the STAR Series.

The STAR  Portfolio has two portfolio  managers,  Jennifer Pline and Barbara J.
McKenna.  Ms.  Pline  has been a  portfolio  manager  of the  STAR  Portfolio's
portfolio since January 1, 1991. Ms. Pline is a Vice President of Standish. Ms.
McKenna has been a portfolio  manager of the STAR  Portfolio's  portfolio since
January  1998.  Ms.  McKenna has served as a Vice  President of Standish  since
1996. Prior to joining Standish, Ms. McKenna managed institutional fixed income
accounts at BayBank.

INVESTMENT SUB-ADVISERS

Allmerica Asset Management,  Inc. (AAM) serves as investment sub-adviser to the
Cash Portfolio. AAM manages the Cash Portfolio,  selects investments and places

the general  supervision of, and policies  established by the Portfolio's Board
of Trustees and  Investors  Bank.  The  business  address of AAM is 440 Lincoln
Street,  Worcester,  Massachusetts  01653.  AAM has been  providing  investment

from Investors Bank (and not from the Portfolio) for its services as investment
sub-adviser.  Prior  to  September  1,  1998,  The  Bank of New  York  acted as
investment sub-adviser for the Portfolio.

M&I Investment Management Corp. ("M&I") serves as investment sub-adviser to the
Treasury  Portfolio and the Treasury Plus  Portfolio.  M&I manages the Treasury
Portfolio and the Treasury Plus Portfolio,  selects  investments and places all
orders for the  purchase and sale of the  Treasury  Portfolio  and the Treasury
Plus  Portfolio's  securities,  subject  to the  general  supervision  of,  and
policies  established by the Portfolios'  Board of Trustees and Investors Bank.
The business  address of M&I is 1000 North Water Street,  Milwaukee,  Wisconsin
53202.  M&I has  been  providing  investment  advisory  services  since  it was

Isley Corporation, a publicly held bank holding company. M&I receives fees from
Investors  Bank (and not from the  Portfolios)  for its services as  investment
sub-adviser.  Prior to January 4, 1999, Aeltus Investment Management, Inc. aced

                            SHAREHOLDER INFORMATION

PURCHASES

GENERAL  INFORMATION.  Shares may be purchased  only  through the  Distributor,
Funds  Distributor,  Inc.,  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 the net asset value (NAV)
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.  Shareholders
may also make general inquiries by calling 1-888-MERRMAC.

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.

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 4:00 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 New York Stock Exchange (NYSE)  (normally 4:00 p.m.

share next determined after

                                       29

<PAGE>

receipt of the order,  provided  that  Investors  Bank receives the wire by the
close of business on the day the purchase order is received.  A Business Day is
any day on which both the NYSE and the New York Federal  Reserve Bank are open,
except  that the  STAR  Series  is open on any day on  which  the NYSE is open.
Purchase  orders  received  after  4:00 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 for the STAR  Series  will be  effected on the
next Business Day if cleared funds are received before the close of business on
the next  Business  Day.  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 3:00 p.m. (ET)
and 4:00 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 the
close of trading on the NYSE for the STAR Series and by 12:00 noon (ET) for the
other Funds.

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 NAV next  determined  after  Investors  Bank has
received  a proper  notice  of  redemption  as  described  below.  If notice of
redemption  is  received  prior to 4:00 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 for the STAR  Series,  on a Business
Day, the redemption  will be effective on the date of receipt.  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 three  Business
Days from the date of receipt.

Shareholder  redemption  requests  received  after 4:00 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, 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 four  Business Days from the date of receipt.
All redemption  requests  regarding  shares of the Cash Series and the Treasury
Plus Series  placed  between 3:00 p.m. and 4:00 p.m. (ET) may only be placed by
telephone.

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 4:00 p.m. (ET) until the
next Business Day.

On days  when  the  financial  markets  close  early,  such  as the  day  after
Thanksgiving  and Christmas Eve, all redemption  orders must be received by the
close of trading on the NYSE for the STAR Series and by 12:00 noon (ET) for the
other Funds.

                                       30

<PAGE>

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.

VALUATION OF SHARES

Each Fund  offers  its shares at the NAV per share of the Fund,  as  determined
once each Business Day. This determination is made as of 4:00 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. Securities purchased by the

                                       31

<PAGE>

Cash  Portfolio,  Treasury  Portfolio and Treasury Plus Portfolio are stated at
amortized cost, which approximates  market value.  Securities  purchased by the
STAR Portfolio are stated at either amortized cost or market value depending on
the nature of the security. If market quotations are not readily available, the
STAR  Portfolio  may value its  assets by a method  that its  Trustees  believe
accurately  reflects fair value. If the STAR Portfolio uses fair value to price
securities,  it may value those securities  higher or lower than another mutual
fund that uses market  quotations.  For more  information on how securities are
valued, see the SAI.

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.  Substantially  all  of  a  Fund's  distributions  will  be  from  net
investment income. Shareholders of the Cash Series, the Treasury Series and the
Treasury Plus 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 next Business Day after their purchase is
effected   through  the  Business  Day  that  their   redemption  is  effected.
Distributions of net capital gains, if any, 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 NAV 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.

Every January,  the Funds provide  information to their  shareholders about the
Funds' dividends and distributions,  which are taxable even if reinvested,  and
about the  shareholders;  redemptions  during the previous  calendar  year. Any
shareholder   who  does  not  provide   the  Funds  with  a  correct   taxpayer
identification  number  and  required  certification  may be subject to federal
backup withholding tax.

Shareholders  should  generally  avoid  investing in a Fund  shortly  before an
expected  taxable  dividend  or  capital  gain   distribution.   Otherwise,   a
shareholder may pay taxes on dividends or  distributions  that are economically
equivalent to a partial return of the shareholder's investment.

Shareholders  should  consult their tax advisers about their own particular tax
situations.

CLASS EXPENSES AND DISTRIBUTION AND SHAREHOLDER SERVICING PLANS

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

The  Institutional  and  Investment  Class of each Fund offers  shares  through
certain   financial   intermediaries,   including   Investors   Bank   (Service
Organizations),  which have entered into shareholder  servicing agreements with
each  Fund.  Service   Organizations   agree  to  perform  certain  shareholder
servicing,  administrative  and  accounting  services  for  their  clients  and
customers who are beneficial  owners of Fund shares.  The Board of Trustees has
approved a  Distribution  Plan with respect to the  Investment  Class shares of
each Fund. Under the Distribution  Plan, the Distribution  Agent is entitled to
receive a fee (as set forth  above)  from each Fund with  respect to the assets
contributed  to such Fund by  shareholders  who are clients or customers of the
Distribution  Agent.  Because  these  fees are paid  out of Fund  assets  on an
ongoing basis,  over time the cost of investing in the Funds may cost more than
paying other types of sales charges.

MASTER/FEEDER STRUCTURE

The Funds are "feeder" funds that invest exclusively in corresponding  "master"
portfolios  with  identical  investment  objectives.  The master  portfolio may
accept   investments  from  multiple  feeder  funds,   which  bear  the  master
portfolio's expenses in proportion to their assets.

Each  feeder  fund and its  master  portfolio  expect  to  maintain  consistent
investment objectives, but if they do not, a Fund will withdraw from the master
portfolio,  receiving either cash or securities in exchange for its interest in
the master  portfolio.  The Trustees would then consider  whether a Fund should
hire its own investment adviser, invest in a different portfolio, or take other
action.

YEAR 2000 READINESS

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.  Each of the above  entities  is
taking  steps that it believes  are  reasonably  designed to address  Year 2000
Readiness  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.


FINANCIAL HIGHLIGHTS

The financial  highlights  table is intended to help you  understand the Funds'
financial performance since the Funds commenced operations. Certain information
reflects  financial  results for a single Fund share.  The total returns in the
table represent the rate that an investor would have earned on an investment in
the Fund  (assuming  reinvestment  of all  dividends and  distributions).  This
information  has  been  audited  by  Ernst & Young  LLP for the  Funds  and the
Portfolios  (and by  PricewaterhouseCoopers  LLP for the  Standish  Portfolio),
whose reports, along with the Funds' financial statements,  are included in the
annual report, which is available upon request.

                                   APPENDIX A

THE  FOLLOWING  ARE  DESCRIPTIONS  OF CERTAIN  TYPES OF SECURITIES IN WHICH THE
PORTFOLIOS' MAY INVEST:

ASSET-BACKED  SECURITIES.  The Cash Portfolio and the STAR Portfolio may invest
in asset-backed securities. The principal and interest payments on asset-backed
securities  are   collateralized  by  pools  of  assets  such  as  credit  card
receivables and categories of receivables,  leases,  installment  sales or loan
contracts and personal property.  Such asset pools are securitized  through the
use of special purpose trusts or  corporations.  Payments or  distributions  of
principal  and interest on  asset-backed  securities  may be  guaranteed  up to
certain  amounts and for a certain  time period by a letter of credit or a pool
insurance policy issued by a financial institution;  however,  privately issued
obligations  collateralized  by a portfolio  of privately  issued  asset-backed
securities  do  not  involve  any  government-related  guaranty  or  insurance.
Asset-backed  securities are  especially  sensitive to prepayment and extension
risk.

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 STAR  Portfolio may invest in commercial  paper with  maturities  which
vary from a few days to nine months.  The Cash Portfolio and the STAR 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 or Fitch.

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.

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.

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.

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.

Mortgage-related   securities  are  especially   sensitive  to  prepayment  and
extension risk. For mortgage  derivatives  and structured  securities that have
imbedded leverage  features,  small changes in interest or prepayment rates may
cause large and sudden price  movements.  Mortgage  derivatives can also become
illiquid and hard to value in declining  markets.  The STAR  Portfolio  may use
mortgage dollar rolls to finance the purchase of additional investments. Dollar
rolls  expose  the STAR  Portfolio  to the risk that it will lose  money if the
additional  investments  do  not  produce  enough  income  to  cover  the  STAR
Portfolio's dollar roll obligations.

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

                                       36

<PAGE>

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%.
The repurchase transactions entered into by the Treasury Plus Portfolio must be
collateralized by securities issued by the U.S. Government.

RESTRICTED  AND  ILLIQUID  SECURITIES.  Each  Portfolio  may invest 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.

SECURITIES  LENDING.  Each Portfolio may lend up to 33 1/3% of its 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.  Loans are subject to  termination  by the Portfolio or
the  borrower at any time and are,  therefore,  not  considered  to be illiquid
investments.

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 AAM or M&I, as applicable.

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.  The Portfolios will only purchase when-issued
and  delayed  delivery  securities  for  the  purpose  of  acquiring  portfolio
securities and not for speculative purposes.

                                       37

<PAGE>

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.

ZERO COUPON AND DEFERRED  PAYMENT  SECURITIES.  The Cash Portfolio and 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. A Portfolio is
required to accrue income with respect to these securities prior to the receipt
of cash payments.  Because the Cash Series and STAR Series will each distribute
its  share of this  accrued  income to  shareholders,  to the  extent  that the
shareholders  and  shareholders  of other  mutual funds that invest in the Cash
Portfolio  or STAR  Portfolio  elect to receive  dividends  in cash rather than
reinvesting  such dividends in additional  shares,  the Cash Portfolio and 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.  The
Treasury  Portfolio and the Treasury  Plus  Portfolio may invest in zero coupon
treasury securities.

                                 FUND HISTORY

Merrimac  Series (the "Trust") is composed of four funds:  Merrimac Cash Series
("Cash  Series"),   Merrimac  Treasury  Series  ("Treasury  Series"),  Merrimac
Treasury Plus Series  ("Treasury  Plus Series") and Merrimac  Short-Term  Asset
Reserve Series ("STAR Series") each, a "Fund" and collectively, the "Funds").

The Trust is a business trust organized under the laws of the State of Delaware
pursuant  to a Master  Trust  Agreement  dated March 30,  1998,  as amended and
registered as an open-end management investment company under the 1940 Act.

The Merrimac Cash Portfolio ("Cash Portfolio"), the Merrimac Treasury Portfolio
("Treasury Portfolio") and the Merrimac Treasury Plus Portfolio ("Treasury Plus
Portfolio")  are each a series or sub-trust of the  Merrimac  Master  Portfolio
(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  Standish   Short-Term  Asset  Reserve   Portfolio  ("STAR
Portfolio")  is a series of the  Standish,  Ayer & Wood Master  Portfolio  (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.  The  Cash  Portfolio,  Treasury
Portfolio, Treasury Plus Portfolio and STAR Portfolio are collectively referred
to as (the "Portfolios").

This SAI is not a  prospectus  and is only  authorized  for  distribution  when
preceded or accompanied by the Trust's  current  Prospectus  dated May 3, 1999,
(the "Prospectus"). This SAI supplements and should be read in conjunction with
the  Prospectus,  a copy of which may be  obtained  without  charge by  calling
1-888-MERRMAC.  This SAI is not an offer of any Fund for which an investor  has
not received a Prospectus.


             DESCRIPTION OF THE FUNDS, THEIR INVESTMENTS AND RISKS

CLASSIFICATION

Each  Fund is a  diversified  open-end,  management  investment  company  and a
separate series of the Trust.

MASTER/FEEDER  STRUCTURE.  Cash Series invests all of its investable  assets in
the Cash Portfolio. Treasury Series invests all of its investable assets in the
Treasury  Portfolio.  Treasury Plus Series invests all of its investable assets
in the  Treasury  Plus  Portfolio.  STAR Series  invests all of its  investable
assets in the STAR Portfolio.  All four Funds are sometimes referred to in this
SAI as feeder funds.

Each  Portfolio  has the same  investment  objective  and  restrictions  as its
corresponding  Fund.  Because the feeder funds  invest all of their  investable
assets  in their  corresponding  Portfolios,  the  description  of each  Fund's
investment  policies,  techniques,  specific investments and related risks that
follows also applies to the corresponding Portfolio.

In addition  to these  feeder  funds,  other  feeder  funds may invest in these
Portfolios,  and  information  about the other  feeder  funds is  available  by
calling 1-888-637-7622 for the Cash Portfolio,  Treasury Portfolio and Treasury
Plus  Portfolio and  1-800-221-4795  for the STAR  Portfolio.  The other feeder
funds  invest  in the  Portfolios  on the same  terms as the  Funds  and bear a
proportionate share of the Portfolio's expenses. The

                                       1

<PAGE>

other  feeder  funds may sell shares on  different  terms and under a different
pricing  structure  than the  Funds,  which may  produce  different  investment
results.

There are  certain  risks  associated  with an  investment  in a  master-feeder
structure.  Large scale  redemptions  by other feeder funds in a Portfolio  may
reduce the  diversification of a Portfolio's  investments,  reduce economies of
scale and increase a Portfolio's  operating expenses.  If the Portfolio Trust's
Board of Trustees approves a change to the investment  objective of a Portfolio
that is not approved by the Trust's Board of Trustees, a Fund would be required
to withdraw  its  investment  in the  Portfolio  and engage the  services of an
investment  adviser or find a substitute  master fund.  Withdrawal  of a fund's
interest  in its  Portfolio,  which may be  required  by the  Trust's  Board of
Trustees without shareholder  approval,  might cause the fund to incur expenses
it would not otherwise be required to pay.


INVESTMENT STRATEGIES AND RISKS

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 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 and the 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

                                       3

<PAGE>

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 ("FNMA").

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
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.  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

                                       4

<PAGE>

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  Government  National
Mortgage Association ("GNMA") Certificates, statistics published by the Federal
Housing  Administration  ("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 GNMA was established in 1968 when the 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,   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 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

                                       5

<PAGE>

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 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

                                       6


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.

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

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 IBCA Investors Service ("Fitch") or Duff and
Phelps ("Duff") 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 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

                                       8

<PAGE>

(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

                                       9

<PAGE>

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  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

                                      10

<PAGE>

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 & 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.

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

                                      11

<PAGE>

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 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.

                                      12

<PAGE>

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.

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  ("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.

                                      13

<PAGE>

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 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. The Cash, Treasury
and Treasury Plus Portfolios may also, with respect to up to 25% of their total
assets,  enter into  contracts  to purchase  securities  for a fixed price at a
future date beyond customary  settlement time. The STAR Portfolio's  limitation
is 10% of its total assets.

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 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.

FUND POLICIES

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  (Series),  the Treasury
Portfolio (Series) and the Treasury Plus Portfolio (Series) 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 (Series)) and the Treasury Plus Portfolio
(Series)) 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 (Series),
Treasury  Portfolio  (Series) or Treasury Plus Portfolio (Series) 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

                                      15

<PAGE>

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 (Series) 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  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  (Series)  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  (Series)  may  be  deemed  to be an  underwriter  under  the
        Securities Act of 1933.

        (4) Purchase or sell real estate except that the Portfolio (Series) 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  (Series)  as a
        result of the ownership of securities.

        (5) Purchase or sell  commodities  or commodity  contracts,  except the
        Portfolio  (Series)  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 (Series') investment policies.

        (6)  Make  loans,  except  that  the  Portfolio  (Series)  (1) may lend
        portfolio  securities  in  accordance  with the  Portfolio's  (Series')
        investment  policies up to 33 1/3% of the  Portfolio's  (Series') 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  (Series')  total
        assets taken at market value to be invested

                                      16

<PAGE>

        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 (Series).

        (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 (Series) may not:

        a. Purchase  securities on margin  (except that the Portfolio  (Series)
        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   (Series')
        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 (Series') 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 (Series)
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
(Series') assets will not constitute a violation of the restriction.

approximately 16.19% of the outstanding interests of the Cash Portfolio.  As of

to take actions regarding their corresponding  Portfolio without the consent or
approval of other interest holders.

                    INVESTMENT ADVISORY AND OTHER SERVICES

INVESTMENT ADVISERS AND SUBADVISERS

The Cash Portfolio, the Treasury Portfolio and the Treasury Plus Portfolio each
retain  Investors Bank & Trust Company  ("Investors  Bank" or the "Adviser") as
their  investment  adviser.  The Investment  Adviser  Agreements  (the "Adviser
Agreements")  between  Investors  Bank  and  each of the  Cash  Portfolio,  the
Treasury Portfolio and the Treasury Plus Portfolio provides that Investors Bank
will manage the operations of the Cash  Portfolio,  the Treasury  Portfolio and
the Treasury Plus 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
and the Treasury Plus Portfolios'  operations and pays the compensation of each
such Portfolio's  officers,  employees and directors  affiliated with Investors
Bank. The Cash Portfolio,  Treasury  Portfolio and Treasury Plus Portfolio each
pays Investors Bank a unitary fee for servicing these  Portfolios as Investment
Adviser,  Administrator,  Custodian,  Fund Accountant and Transfer Agent. For a

Portfolio and the Treasury Plus  Portfolio pay Investors Bank under the Adviser
Agreements, see "Administrator, Transfer Agent and Fund Accountant" below.

Each  Portfolio  pays  Investors  Bank a fee for its services.  The fee paid to
Investors  Bank by the Cash  Portfolio  for the fiscal year ended  December 31,

Pursuant  to  an  Investment   Sub-Adviser   Agreement  (the  "AAM  Sub-Adviser
Agreement"),  Investors  Bank has retained  Allmerica  Asset  Management,  Inc.
("AAM") as sub-adviser to the Cash  Portfolio.  AAM is compensated by Investors
Bank at no additional cost to the Cash Portfolio. Subject to the supervision of
Investors Bank and of the Portfolio Trust's Board of Trustees, AAM furnishes to
the Cash Portfolio investment  research,  advice and supervision and determines
what securities will be purchased,  held or sold by the Cash Portfolio.  AAM is
rendered an annual fee,  computed  and paid  monthly,  based on the average net
assets ("ANA") of the Cash Portfolio according to the following schedule: 0.09%
on the first $500 million in assets;  0.07% on the next $500 million in assets,
and 0.06% on assets exceeding $1 billion.  Prior to September 1, 1998, the Cash
Portfolio  was  advised by The Bank of New York  ("BNY") and was paid an annual
fee,  computed  and  paid  monthly,  based  on  0.08%  of the  ANA of the  Cash
Portfolio.  The amount paid by Investors  Bank to BNY for the period January 1,
1998 to August 31, 1998 was $429,014.  The amount paid by Investors Bank to AAM
for the period September 1, 1998 to December 31, 1998 was $233,588.

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  Portfolio  and  the  Treasury  Plus
Portfolio.  M&I is compensated  by Investors Bank at no additional  cost to the
Treasury Portfolio and the Treasury Plus Portfolio.  Subject to the supervision
of Investors Bank and of the Portfolio Trust's Board of Trustees, M&I furnishes
to the Treasury Portfolio and the Treasury Plus Portfolio  investment research,
advice and supervision  and determines what securities will be purchased,  held
or sold by the Treasury  Portfolio  and the  Treasury  Plus  Portfolio.  M&I is
rendered an annual fee, computed and paid monthly, based on 0.08% of the ANA of
each of the Treasury Portfolio and the Treasury Plus Portfolio.  For the fiscal
year ended  December 31, 1998,  the  Treasury  Portfolio  was advised by Aeltus
Investment Management, Inc. ("Aeltus") and Aeltus received the same fees as M&I
currently receives.  The amount paid by Investors Bank to Aeltus for the fiscal
year ended  December 31, 1998 was $46,158.  The Treasury Plus Portfolio had not
commenced operations as of December 31, 1998.

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 Series and the  Standish  STAR Fund invests all of
its investable assets in the STAR Portfolio as a separate management investment
company.

DISTRIBUTOR

The  Premium,  Institutional  and  Investment  Class  shares  of the  Funds are
continuously  distributed  by  Funds  Distributor,   Inc.  (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  Bank for
services it performs in acting as the Funds' Distributor.

Funds Distributor is registered with the SEC as a broker-dealer and is a member
of the National Association of Securities Dealers. Funds Distributor is located
at 60 State Street, Suite 1300, Boston,  Massachusetts 02109. Funds Distributor
is an indirect  wholly-owned  subsidiary of Boston Institutional Group, Inc., a

DISTRIBUTION AND SHAREHOLDER SERVICING PLANS

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

                                      24

<PAGE>

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.

pays Investors Bank an aggregate fee,  calculated daily and paid monthly, at an
annual rate of 0.03% of ANA of the STAR Series.

                   BROKERAGE ALLOCATION AND OTHER PRACTICES

Purchases  and sales of  securities  for the Cash,  Treasury and Treasury  Plus
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  Portfolio  and the  Treasury  Plus
Portfolio do not anticipate paying brokerage  commissions.  Any transaction for
which the Cash  Portfolio,  Treasury  Portfolio or the Treasury Plus  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
Series  and the  Treasury  Plus  Series  and the  other  investors  in the Cash
Portfolio, Treasury Portfolio or the Treasury Plus Portfolio rather than by any
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  Portfolio  and the
Treasury Plus  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 Portfolio or the
Treasury  Plus  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  Portfolio  or the  Treasury  Plus
Portfolio  or the  size of the  position  obtainable  for the  Cash  Portfolio,
Treasury Portfolio or the Treasury Plus Portfolio.  In addition, when purchases
or sales of the same security for the Cash Portfolio, Treasury Portfolio or the
Treasury Plus  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.

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

                                      26

<PAGE>

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 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.

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.

                                 CAPITAL STOCK

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.

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.

                                       28

<PAGE>

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.

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  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


                 PURCHASE, REDEMPTION AND VALUATION OF SHARES

PURCHASE AND REDEMPTION OF SHARES

Information  on how to  purchase  and  redeem  shares and the time at which net
asset value of each share is determined 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  Commission may permit for
the protection of shareholders of the Fund.

                                      29

<PAGE>

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
Series,  may  make  payment  wholly  or  partly  in  portfolio  securities,  in
conformity  with a rule  of the  Commission.  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.

VALUATION OF SHARES

The following is a description of the  procedures  used by the Funds in valuing
their assets.

CASH PORTFOLIO,  TREASURY PORTFOLIO AND TREASURY PLUS PORTFOLIO. The investment
securities in the Cash Portfolio,  the Treasury Portfolio and the Treasury Plus
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  Portfolio or Treasury Plus 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  Series or the  Treasury  Plus
Series at $1.00;  however,  there can be no assurance that the Cash Series, the
Treasury  Series or the Treasury  Plus 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 Treasury bills.

                             TAXATION OF THE TRUST

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 Internal  Revenue Code of 1986, as amended (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 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 a 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 Fund

                                      31

<PAGE>

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 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 Fund 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.

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

                                      32

<PAGE>

(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 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 

                                      33

<PAGE>

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  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

From time to time, the Cash Series,  the Treasury  Series and the Treasury Plus
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  Series and the Treasury
Plus  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 Funds' 7-day yield for the period ended December 31, 1998, were as follows:

</TABLE>

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 (NAV) per share on the last day of the period.


        The 30 day yield for the STAR Series for the period ended  December 31,
        1998 was ________%.

EFFECTIVE YIELD

In addition,  the Cash Series, the Treasury Series and the Treasury Plus Series
may calculate a 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 Funds may advertise performance in terms of average annual total return for
1-, 5-, and 10 year  periods,  or for such lesser  periods as any of such Funds
have been in existence.  Average annual total return is computed by finding the
average  annual  compounded  rates of return over the periods that would equate
the initial  amount  invested to the ending  redeemable  value,  according  the
following formula: 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 Funds'  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 Series may compare
its performance to The  IBC/Donoghue  Money Market  Average/All  Taxable Index,
which is  generally  considered  to be

                                      36

<PAGE>

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.

The Cash Series began  operations  on June 25, 1998.  The average  annual total
return for the  Premium  Class of the  Merrimac  Cash Fund (which is a separate
feeder  fund that  invests  all of its  assets in the Cash  Portfolio)  for the
fiscal year ended December 31, 1998 was 5.59%.

The Treasury Series began operations on June 25, 1998. The average annual total
return for the Premium Class of Fund is 4.80%.  This  performance  represents a
blend of the performance for the Premium Class of the Merrimac Treasury Fund (a
separate feeder fund that invests all of its assets in the Treasury  Portfolio)
for the period January 1, 1998 to June 24, 1998 and the performance for Premium
Class of the Fund from June 24, 1998 to December 31, 1998.

The Treasury Plus Series is newly operational and therefore does not have total
return information for the period ended December 31, 1998.

The STAR Series began  operations  on August 7, 1998.  The total return for the
Standish  STAR Fund,  which is a separate  feeder fund that  invests all of its
assets in the STAR Portfolio,  for the one, five and ten year period  beginning
January 3, 1989 (inception of the Standish STAR Fund) through December 31, 1998
was ____%, ____% and ____%, respectively.

Each  Fund's  performance  will vary from time to time  depending  upon  market
conditions,  the combustion of the Fund's portfolio and its operating expenses.
As described  above,  total return is based on  historical  earnings and is not
intended to indicate future  performance.  Consequently,  any given performance
quotation should not be considered as  representative  of a Fund's  performance
for any specified period in the future.  Performance  information may be useful
as a basis for comparison with other investment alternatives. However, a Fund's
performance will fluctuate,  unlike certain bank deposits or other  investments
which pay a fixed yield for a stated period of time.

DESCRIPTION OF COMMERCIAL PAPER RATINGS

The following  descriptions  of short-term  debt ratings have been published by
Standard & Poor's  Ratings  Service  ("Standard & Poor's"),  Moody's  Investors
Service  ("Moody's"),  Fitch's IBCA Investors Service  ("Fitch"),  and Duff and
Phelps ("Duff"),  respectively. These obligations have an original maturity not
exceeding thirteen months, unless explicitly noted.

A -- Standard & Poor's  commercial paper rating is a current  assessment of the
likelihood  of timely  payment of debt  considered  short-term  in the relevant
market.  Commercial  paper issues rated A-1 by Standard & Poor's reflect a very
strong degree of safety of timely  payment.  Commercial  paper issues rated A-2
reflect a strong  degree of safety of timely  payment  but not as strong as for
issues designated A-1.

Commercial paper issues rated Prime-1 by Moody's are judged by Moody's to be of
the  "highest"  quality  on the basis of  relative  repayment  capacity  with a
superior  ability  for  repayment  of  senior   short-term  debt   obligations.
Commercial  paper  issues  rated  Prime-2  are  judged by  Moody's to be of the
"second  highest"  quality  with a  strong  ability  for  repayment  of  senior
short-term debt obligations.

The rating Fitch-1 (Highest Grade) is the highest commercial rating assigned by
Fitch.  Paper  rated  Fitch-1 is  regarded  as having the  strongest  degree of
assurance  for timely  payment.  Commercial  paper  issues  rated  Fitch-2  are
regarded as having only a slightly less  assurance of timely payment than those
issues rated Fitch-1.

The rating  Duff-1 is the highest  commercial  paper  rating  assigned by Duff.
Paper rated Duff-1 is regarded as having very high  certainty of timely payment
with excellent  liquidity factors that are supported by ample asset protection.
Risk factors are minor.  The rating Duff-2 is regarded as having good certainty
of  timely  payment  with  sound  liquidity  factors  supported  by good  asset
protection. Risk factors are small.

DESCRIPTION OF LONG-TERM DEBT RATINGS

The following is a description of Moody's debt instrument ratings:

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

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

                                      38

<PAGE>

Moody's  applies  numerical  modifiers  1,  2  and  3 in  each  generic  rating
classification.  The  modifier 1  indicates  that the  obligation  ranks in the
higher end of its generic rating category;  the modifier 2 indicates a midrange
ranking;  and the  modifier  3  indicates  a  ranking  in the lower end of that
generic rating category.

The following is a description of Standard & Poor's debt instrument ratings:

Standard & Poor's  ratings  are based,  in varying  degrees,  on the  following
considerations:  (i) the  likelihood of default -- capacity and  willingness of
the obligor as to the timely  payment of interest and repayment of principal in
accordance with the terms of the obligations; (ii) the nature of and provisions
of the obligation;  and (iii) the protection afforded by, and relative position
of,  the  obligation  in the  event  of  bankruptcy,  reorganization,  or other
arrangement  under the laws of bankruptcy and other laws  affecting  creditors'
rights.

AAA -- Debt rated AAA has the  highest  rating  assigned  by Standard & Poor's.
Capacity to pay interest and repay principal is extremely strong.

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

Plus (+) or minus (-): The ratings may be modified by the addition of a plus or
minus sign to show relative standing within the major rating categories.

BANK WATCH SHORT-TERM DEBT RATINGS

THOMSON BANK WATCH  ratings  represent an  assessment  of the  likelihood of an
untimely  payment  of  principal  and  interest.  Important  factors  that  may
influence this  assessment are the overall  financial  health of the particular
company,  and the  probability  that the  government  will come to the aid of a
troubled institution in order to avoid a default or failure. The probability of
government intervention stems from four primary factors:

          O  GOVERNMENT GUARANTEES

          O  GOVERNMENT OR QUASI-GOVERNMENT OWNERSHIP OR CONTROL

          O  THE DEGREE OF CONCENTRATION IN THE BANKING SYSTEM

          O  GOVERNMENT PRECEDENT

As with the Issuer  Ratings,  the  Short-Term  Debt  Ratings  incorporate  both
qualitative  and  quantitative  factors.  The  ratings  are  not  meant  to  be
"pass/fail"  but rather to provide a relative  indication of  creditworthiness.
Therefore, obligations rated TBW-3 are still considered investment-grade.

These  Short-Term  Debt  Ratings  can  also be  restricted  to  local  currency
instruments.  In such cases, the ratings will be preceded by the designation LC
for Local  Currency.  Short-Term  Debt Ratings are based on the following scale
and the definitions are:

TBW-1                                                                 LC-1
          The highest category; indicates a very high likelihood that principal
          and interest will be paid on a timely basis.

TBW-2                                                                 LC-2
          The  second-highest  category;  while the degree of safety  regarding
          timely  repayment of principal  and interest is strong,  the relative
          degree of safety is not as high as for issues rated TBW-1.

TBW-3                                                                 LC-3 
          The  lowest  investment-grade  category;  indicates  that  while  the
          obligation is more susceptible to adverse developments (both internal
          and external) than those with higher ratings, the capacity to service
          principal and interest in a timely fashion is considered adequate.

TBW-4                                                                 LC-4
          The lowest rating category; this rating is regarded as non-investment
          grade and therefore speculative.

BANK WATCH LONG-TERM DEBT RATINGS

Long-Term  Debt  Ratings  assigned  by THOMSON  BANK  WATCH ALSO WEIGH  HEAVILY
GOVERNMENT  OWNERSHIP AND SUPPORT. The quality of both the company's management
and  franchise  are of even greater  importance  in the  Long-Term  Debt Rating
decisions.  Long-Term  Debt  Ratings look out over a cycle and are not adjusted
frequently for what is believed to be short-term performance aberrations.

Long-Term  Debt Ratings can be restricted to local currency debt - ratings will
be identified by the  designation  LC. In addition,  Long-Term Debt Ratings may
include a plus (+) or minus (-) to indicate where within the category the issue
is placed. BANK WATCH Long-Term Debt Ratings are based on the following scale:

INVESTMENT GRADE

AAA                                                                   LC-AAA
          Indicates  that the  ability to repay  principal  and  interest  on a
          timely basis is extremely high.

AA                                                                    LC-AA
          Indicates a very strong ability to repay  principal and interest on a
          timely  basis,  within  limited  incremental  risk compared to issues
          rated in the highest category.

A                                                                     LC-A
          Indicates  the  ability to repay  principal  and  interest is strong.
          Issues rated A could be more vulnerable to adverse developments (both
          internal and external) than obligations with higher ratings.

BBB                                                                   LC-BBB
          The  lowest  investment-grade   category;   indicates  an  acceptable
          capacity  to  repay  principal  and  interest.  BBB  issues  are more
          vulnerable to adverse  developments (both internal and external) than
          obligations with higher ratings.

NON-INVESTMENT GRADE - MAY BE SPECULATIVE IN THE LIKELIHOOD OF TIMELY REPAYMENT
OF PRINCIPAL AND INTEREST.

BB                                                                    LC-BB
          While  not  investment   grade,  the  BB  rating  suggests  that  the
          likelihood  of  default  is  considerably  less than for  lower-rated
          issues.  However,  there are  significant  uncertainties  that  could
          affect the ability to adequately service debt obligations.

B                                                                     LC-B
          Issues  rated B show a higher  degree of  uncertainty  and  therefore
          greater  likelihood  of default  than  higher-rated  issues.  Adverse
          developments  could  negatively  affect the payment of  interest  and
          principal on a timely basis.

CCC                                                                   LC-CCC
          Issues  rated CCC clearly  have a high  likelihood  of default,  with

ITEM 24.  PERSONS CONTROLLED BY OR UNDER COMMON CONTROL WITH THE TRUST.

A list of all persons  directly or  indirectly  under  common  control with the
Registrant which indicates  principal  business of each such company referenced
is incorporated herein by reference to Item 25 of the Registration Statement on
Form N-1A (File No. 811-07941), as filed electronically with the Securities and
Exchange Commission on March 28, 1997.

ITEM 25.  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,

<PAGE>

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  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.

     Agreement  made  as of this  4th  day of  January,  1999,  by and  between

     WHEREAS,  the MERRIMAC  TREASURY PLUS  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

Act");

     WHEREAS,  the  Merrimac  Treasury  Plus Series (the  "Fund"),  which is an
open-end diversified  management investment company registered as such with the
SEC pursuant to the 1940 Act and the Securities Act of 1933, 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:

1.  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 give the
Portfolio and the Trust's Board of Trustees  (the  "Trustees"),  the 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 Prospectus and Statement
of Additional  Information ("SAI"), the Portfolio's  Registration  Statement on
Form N-1A and any federal  and state laws:  (i)  regularly  provide  investment
advice and  recommendations  to the Portfolio,  with respect to the Portfolio's
investments,  investment policies 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

<PAGE>

     foregoing to the Trust in such detail as the Trust may reasonably  deem to
be  appropriate  in 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 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.

5.  Interested Trustees or Parties

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

6.  Services Not Exclusive

     The  services  of  the  Adviser  to the  Portfolio  are  not to be  deemed
exclusive,  the 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 Adviser's ability to meet all of its obligations hereunder.

                                       2

<PAGE>

7.  Compliance; Books and Records

     (a) The  Adviser  agrees to maintain  adequate  compliance  procedures  to
ensure its compliance  with the  applicable  provisions of the 1940 Act and any
rules  or  regulations  thereunder,  the  investment  objective,  policies  and
restrictions  of the Portfolio as set forth in the current Fund  Prospectus and
SAI and any other applicable provisions of state or federal law.

     (b)  The  Adviser  shall  furnish  to the  Portfolio,  at the  Portfolio's
expense,  copies of all records  prepared in connection with the performance of
this Agreement and the  maintenance of compliance  procedures  pursuant to this
Section 7 as the Portfolio may reasonably request.

     (c)  The  Adviser  agrees  to  provide  upon  reasonable  request  of  the

the property of the Trust and further agrees to surrender promptly to the Trust
any of such records upon the Trust's  request.  The Adviser  further  agrees to
preserve  for the  periods  prescribed  by Rule  31a-2  under  the 1940 Act the
records required to be maintained by Rule 31a-1 under the 1940 Act. The Adviser
will  treat  confidentially  and as  proprietary  information  of the Trust all
records  and other  information  relative  to the Fund and  prior,  present  or
potential shareholders, except as otherwise required by law.

8.  Limitation of Liability of Adviser

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

9.  Duration, Amendment and Termination

     (a) Subject to prior  termination as provided in  sub-section  (d) of this
Section 9, 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 Trustees or by vote of a majority of
the outstanding voting securities of the Portfolio and the Fund.

     (b) This Agreement may be modified by the written Agreement of the Adviser
and the  Portfolio,  such consent on the part of the Portfolio to be authorized
by vote of a majority of the outstanding voting securities of the Portfolio and
the  Fund if  required  by law.  The  execution  of any  such  modification  or
amendment  by a party shall  constitute  a  representation  and warranty to the
other party 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 9, the terms of any  continuance or  modification 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 or the  Portfolio  may,  at any time on sixty (60)
days'  prior  written  notice to the other  party,  terminate  this  Agreement,
without payment of any penalty, and in the case of the Portfolio,  by action of
its Trustees, or by vote of a majority of its outstanding voting securities.

                                       3

<PAGE>

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

     (f)  Termination of this  Agreement  shall not relieve the Adviser nor the
Trust 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 Adviser
shall be returned to the Portfolio as soon as reasonably  practicable after the
termination of this Agreement.

10. Disclaimer of Liability; Several Obligations

     The  Adviser  understands  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.

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

11. Miscellaneous

     (a) The terms "vote of a majority of the outstanding  voting  securities,"
"assignment,"  and  "interested  persons,"  when used  herein,  shall  have the
respective  meanings specified in the 1940 Act as now in effect or as hereafter
amended.

     (b) The  captions  in this  Agreement  are  included  for  convenience  of
reference only and in no way define or delimit any of the provisions  hereof or
otherwise affect their construction or effect.

     (c) 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.

     (d) This  Agreement  shall be binding upon and shall insure to the benefit
of the parties hereto and their respective successors.

     (e) The Adviser's duties and  responsibilities  are solely those set forth
herein and no other covenant or obligation shall be implied against the Adviser
in connection with this Agreement.

     (f) This  Agreement  may be  executed in two or more  counterparts,  which
taken together shall constitute one and the same instrument.

     (g) Any notice under this  Agreement  shall be in writing,  addressed  and
delivered  or mailed,  postage  prepaid,  to the other party at such address as
such other party may designate for the receipt of such notice.  No notice shall
be effective until received.

     IN WITNESS WHEREOF, the parties have caused this instrument to be executed
by their  respective  officers  designated  below as of the day and year  first
above written.

willful  misfeasance,  bad faith or negligence in the performance of its duties

         respect to such modification or amendment have been obtained.

         (c) In addition to the  requirements  of  sub-sections  (a) and (b) of

         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.

investment  companies and the Fund and the Portfolio  have the same  investment

objectives and substantively the same investment policies;
         
     WHEREAS,  the Adviser  currently  serves as the investment  adviser of the
Portfolio;
         
     WHEREAS,  the Trust desires to invest all of the Fund's  investable assets

in the Portfolio in exchange for a beneficial  interest in the  Portfolio  (the

"Investment") on the terms and conditions set forth in this Agreement;
        
WHEREAS, the Portfolio Trust is willing to accept the Investment; and
         
     NOW,  THEREFORE,  in consideration  of the foregoing,  the mutual promises

herein  made and  other  good  and  valuable  consideration,  the  receipt  and

sufficiency of which are hereby acknowledged, the parties agree as follows:

                                       I

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

1.1   Agreement to Effect the Investment.  The Trust agrees to assign, transfer
      ----------------------------------
and deliver all of the Fund's investable assets (the "Assets") to the Portfolio

Trust at each Closing (as hereinafter  defined).  The Portfolio Trust agrees in

                            CLOSING AND CLOSING DATE
                            ------------------------

     2.1   Time of Closing.  The conveyance of the Assets in exchange for the
           ---------------
Interest,  as described in Article I, together  with related acts  necessary to

consummate  such  transactions,  shall  occur  initially  on the date the Trust

commences  its  offering  of  shares  of the  Fund  to the  public  and at each

subsequent  date as the  Trust  desires  to make a  further  Investment  in the

Portfolio (each, a "Closing").  Except as otherwise provided in Section 4.1(j),

all acts occurring at any Closing shall be deemed to occur simultaneously as of

the determination of the Portfolio's net asset value on the date of Closing.
     
         
     2.2   Related Closing Matters.  On each date of Closing, the Trust, on
           -----------------------

Portfolio's  custodians  shall  acknowledge,  in a form acceptable to the other

party,  their respective  delivery and acceptance of the Assets.  The Portfolio

shall deliver to the Trust  acceptable  evidence of the Fund's ownership of the

Interest. In addition,  each party shall deliver to each other party such bills

of  sale,  checks,  assignments,  securities  instruments,  receipts  or  other

documents as such other party or its counsel may  reasonably  request.  Each of

the  representations and warranties set forth in Article III shall be deemed to

have been made anew on each date of Closing.

     2.3   Rejection of Certain Assets.  The Portfolio Trust may refuse to
           ---------------------------
accept Assets other than in the form of cash if: (a)  acceptance of such Assets

or the  issuance of an Interest in exchange  therefor at that time would result

in a  violation  of any of the  Portfolio's  policies  or  restrictions  or any

provision of the 1940 Act; (b) such Assets do not have a readily  ascertainable

market value;  or (c)  acceptance of such Assets at that time would result,  in

the absence of corrective  action by the Adviser or otherwise,  in any investor

in the  Portfolio  failing to qualify as a regulated  investment  company under

Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code").

                    ---------

Investments  in the  Portfolio  (i) on any day on  which  the  Portfolio  Trust

refuses to permit  all other  investors  in the  Portfolio  to make  additional

Investments in the Portfolio or (ii) in the event the Trustees of the Portfolio

Trust have reasonably determined that permitting additional  Investments by the

Fund in the Portfolio would  constitute a breach of their  fiduciary  duties to

the Portfolio.

     4.3     Indemnification by the Adviser.
             ------------------------------

            (a) The Adviser will  indemnify and hold harmless  Investors  Bank,

the Trust, and their respective Trustees, directors, officers and employees and

each other person who controls  Investors  Bank,  the Trust or the Fund, as the

case may be,  within  the  meaning  of  Section  15 of the 1933  Act  (each,  a

"Merrimac  Covered  Person"  and  collectively,  "Merrimac  Covered  Persons"),

against any and all losses, claims, demands, damages,  liabilities and expenses

(each, a "Liability" and collectively,  the "Liabilities")  (including,  unless

the Adviser elects to assume the

                                       10

<PAGE>

defense pursuant to paragraph (b), the reasonable  costs of  investigating  and

defending  against  any  claims  therefor  and any  counsel  fees  incurred  in

connection  therewith),   joint  or  several,   whether  incurred  directly  or

indirectly by the Trust through the Trust's Investment in the Portfolio, which
                  
                    (i) arise out of or are  based  upon any of the  Securities

Laws, any other statute or common law or are incurred in connection  with or as

a result of any formal or informal  administrative  proceeding or investigation

by a regulatory  agency,  insofar as such Liabilities arise out of or are based

upon the  ground or alleged  ground  that any direct or  indirect  omission  or

commission  by the  Portfolio  Trust  (either  during  the  course of its daily

activities or in  connection  with the accuracy or its  representations  or its

warranties in this Agreement) caused or continues to cause the Trust to violate

any federal or state  securities  laws or regulations  or any other  applicable

domestic or foreign law or regulations or common law duties or obligations, but

only to the extent that such  Liabilities do not arise out of and are not based

upon an omission or commission of the Fund, Trust or IBT;
                     
                    (ii)  arise  out  of  or  are  based  upon  an   inaccurate

calculation  of the  Portfolio's  net asset value which is considered  material

under  procedures  adopted  by the Board of  Trustees  of the  Portfolio  Trust

(whether by the Portfolio, the Adviser or any party retained for that purpose);
                   
                    (iii)  arise  out  of (A)  any  alleged  misstatement  of a

material  fact or an  omission  of a  material  fact in the  Portfolio  Trust's

registration statement (including amendments thereto) or in disclosure included

at  the  Adviser's  or  Portfolio  Trust's  request  in  advertising  or  sales

literature  used by the Fund, or (B) any  misstatement of a material fact or an

omission of a material fact in the registration statement of an investor in the

Portfolio, other than the Trust;

                    (iv) arise out of the Portfolio's having caused the Fund to

fail to qualify as a regulated investment company under the Code;

                    (v)  result  from  the  failure  of any  representation  or

warranty made by the Portfolio Trust or Adviser to be accurate when made or the

failure of the  Portfolio  Trust or Adviser to perform any  covenant  contained

herein or to otherwise comply with the terms of this Agreement;

                                       11

<PAGE>
                    (vi)  arise out of any  unlawful  or  negligent  act by the

Portfolio Trust,  the Adviser or any director,  trustee,  officer,  employee or

agent of the Portfolio Trust or Adviser, whether such act was committed against

the Portfolio, the Trust or any third party; or

                    (vii)  result from any  Liability  of the  Portfolio to any

investor in the Portfolio (or  shareholder  thereof),  other than the Fund (and

its shareholders);

                    provided, however, that in no case shall the Adviser be
                    -----------------
liable with respect to any claim made against any such Merrimac  Covered Person

unless such Merrimac  Covered Person shall have notified the Adviser in writing

of the nature of the claim  within a reasonable  time after the summons,  other

first  legal  process  or  formal  or  informal   initiation  of  a  regulatory

investigation  or  proceeding  shall have been  served  upon or  provided  to a

Merrimac Covered Person or any federal,  state or local tax deficiency has come

to the attention of the Trust, or another Merrimac  Covered Person.  Failure to

notify the Adviser of such claim shall not relieve it from any  liability  that

it may have to any Merrimac  Covered  Person  otherwise  than on account of the

indemnification contained in this paragraph.

            (b) The Adviser will be entitled to  participate at its own expense

in the defense or, if it so elects,  to assume the defense of any suit  brought

to  enforce  any such  liability,  but,  if the  Adviser  elects to assume  the

defense,  such defense shall be conducted by counsel chosen by the Adviser.  In

the event the Adviser  elects to assume the defense of any such suit and retain

such  counsel,  each  Merrimac  Covered  Person  and  any  other  defendant  or

defendants  in the suit may retain  additional  counsel but shall bear the fees

and expenses of such  counsel  unless (A) the Adviser  shall have  specifically

authorized  the  retaining  of such  counsel  or (B) the  parties  to such suit

include any  Merrimac  Covered  Person and the Adviser,  and any such  Merrimac

Covered  Person has been advised by counsel that one or more legal defenses may

be available to it that may not be available to the Adviser,  in which case the

Adviser   shall  not  be   entitled   to  assume  the   defense  of  such  suit

notwithstanding  the  obligation to bear the fees and expenses of such counsel.

The Adviser  shall not be liable to indemnify any Merrimac  Covered  Person for

any  settlement  of any such  claim  effected  without  the  Adviser's  written

consent,  which  consent  shall not be  unreasonably  withheld or delayed.  The

indemnities  set forth in  paragraph  (a) will be in addition to any  liability

that the Portfolio might otherwise have to a Merrimac Covered Person.

     4.4     Indemnification by Investors Bank.
             ---------------------------------

            (a)  Investors  Bank will  indemnify and hold harmless the Adviser,

the Portfolio  Trust, and their respective  Trustees,  directors,  officers and

or the  Portfolio,  as the case may be, within the meaning of Section 15 of the

1933 Act (each, a "Standish Covered Person" and collectively, "Standish Covered

Persons"),  against  any and all  Liabilities  (as  defined in Section  4.3(a))

(including,  any  amounts  the  Adviser is  obligated  to pay  pursuant  to its

indemnification obligation under Section 4.3, and, unless Investors Bank elects

to assume the defense  pursuant  to  paragraph  (b),  the  reasonable  costs of

investigating  and defending  against any claims  therefor and any counsel fees

incurred in connection therewith),  joint or several, whether incurred directly

or indirectly by the Adviser, the Portfolio Trust, which

                    (i) arise out of or are  based  upon any of the  Securities

Laws, any other statute or common law or are incurred in connection  with or as

a result of any formal or informal  administrative  proceeding or investigation

by a regulatory  agency,  insofar as such Liabilities arise out of or are based

upon the  ground or alleged  ground  that any direct or  indirect  omission  or

commission by Investors  Bank,  the Trust or Fund (either  during the course of

its daily activities or in connection with the accuracy or its  representations

or its warranties in this Agreement) caused or continues to cause the Portfolio

Trust to violate any federal or state  securities  laws or  regulations  or any

other applicable domestic or foreign law or regulations or common law duties or

obligations,  but only to the extent that such  Liabilities do not arise out of

and are not based upon an omission or commission of the Adviser,  the Portfolio

Trust or the Portfolio;
                     
                    (ii)  arise  out  of  or  are  based  upon  an   inaccurate

calculation  of the  Portfolio's  net  asset  value  by  Investors  Bank or its

affiliates as custodian or administrator of the Portfolio (which calculation is

considered material under procedures approved by the Portfolio Trust's Board of

Trustees),  to the extent such  inaccurate  calculation is  attributable to the

negligence of Investors Bank or its affiliates;
                     
                    (iii) arise out of any alleged  misstatement  of a material

fact or an omission of a material  fact in the Trust's  registration  statement

(including  amendments  thereto) or in disclosure  included in  advertising  or

sales literature used by the Fund or the Trust's principal underwriter,  except

to the extent such misstatement or omission was (a) also contained

                                       13

<PAGE>

in the Portfolio Trust's registration  statement (including amendments thereto)

and was included in the Trust's registration statement in conformity therewith;

or (b) in  disclosure  provided by the Adviser or the  Portfolio  Trust for the

express purpose of its inclusion in the Trust's registration statement or sales

literature;
               
                    (iv) arise out of the Fund's having caused the Portfolio to

fail to qualify as a partnership under the Code;

                    (v)  result  from  the  failure  of any  representation  or

warranty  made by the Trust or Investors  Bank to be accurate  when made or the

failure of the Trust or Investors Bank to perform any covenant contained herein

or to otherwise comply with the terms of this Agreement;

                    (vi)  arise out of any  unlawful  or  negligent  act by the

Trust or Investors Bank or any director, trustee, officer, employee or agent of

the  Trust or  Investors  Bank,  whether  such act was  committed  against  the

Portfolio Trust, the Portfolio, the Adviser or any third party; or
                        
                    (vii)   arise  out  of  or  are  based  upon  any   alleged

misstatement or misrepresentation of a material fact (other than in the Trust's

registration  statement  or sales  literature  used by the Fund) by, or alleged

misleading  or  fraudulent  sales  practices of,  Investors  Bank,  the Trust's

principal underwriter, or their respective representatives.

                    provided, however, that in no case shall Investors Bank be
                    -----------------
liable with respect to any claim made against any such Standish  Covered Person

unless such  Standish  Covered  Person shall have  notified  Investors  Bank in

writing of the nature of the claim within a reasonable  time after the summons,

other first  legal  process or formal or informal  initiation  of a  regulatory

investigation  or  proceeding  shall have been  served  upon or  provided  to a

Standish Covered Person or any federal,  state or local tax deficiency has come

to the attention of the Portfolio  Trust, or another  Standish  Covered Person.

Failure to notify  Investors  Bank of such claim  shall not relieve it from any

liability  that it may have to any Standish  Covered  Person  otherwise than on

account of the indemnification contained in this paragraph.
             
            (b)  Investors  Bank will be  entitled  to  participate  at its own

expense in the defense  or, if it so elects,  to assume the defense of any suit

brought to enforce any such liability,  but, if Investors Bank elects to assume

the  defense,  such defense  shall be conducted by counsel  chosen by Investors

Bank. In the event Investors Bank elects to assume the defense of any such suit

and

                                       14

<PAGE>

retain such counsel,  each Standish  Covered Person and any other  defendant or

defendants  in the suit may retain  additional  counsel but shall bear the fees

and expenses of such counsel unless (A) Investors Bank shall have  specifically

authorized  the  retaining  of such  counsel  or (B) the  parties  to such suit

include any Standish  Covered Person and Investors  Bank, and any such Standish

Covered  Person has been advised by counsel that one or more legal defenses may

be available to it that may not be available to Investors  Bank,  in which case

Investors  Bank  shall not be  entitled  to  assume  the  defense  of such suit

notwithstanding  the  obligation to bear the fees and expenses of such counsel.

Investors Bank shall not be liable to indemnify any Standish Covered Person for

any  settlement of any such claim  effected  without  Investors Bank 's written

consent,  which  consent  shall not be  unreasonably  withheld or delayed.  The

indemnities  set forth in  paragraph  (a) will be in addition to any  liability

that the Fund might otherwise have to a Standish Covered Person.

     4.5     In-Kind Redemption.
             ------------------

            (a) In the event the Trust  desires  to  withdraw  or redeem all or

part of the Fund's  Interests in the Portfolio,  unless otherwise  agreed,  the

Portfolio  Trust may in its discretion  effect such redemption in whole or part

in kind  provided  that to the extent any such  redemption is to be effected in

kind: (a) it shall be in compliance with the Portfolio  Trust's  election under

Rule 18f-1 of the 1940 Act unless such  election  has been  revoked by order of

the SEC or otherwise made  ineffective  by a published  position of specific or

general  application of the SEC or the SEC staff;  and (b) it shall be effected

in such a manner that the securities  delivered to the Fund's custodian for the

account of the Fund shall mirror, as closely as practicable, the composition of

the Portfolio immediately prior to such redemption.

            (b) It is agreed that in the event of a  redemption  in-kind  which

represents  either a complete or partial  withdrawal of the Fund's  Interest in

the Portfolio,  the Portfolio  Trust need not deliver to the Trust's  custodian

any portfolio securities the distribution of which to the Trust would result in

the  recognition of taxable gain to any other  investor in the Portfolio  which

had contributed such security to the Portfolio.

     4.6     Reasonable Actions.  Each party covenants that it will, subject to
             ------------------
the provisions of this  Agreement,  from time to time, as and when requested by

another party or in its own discretion, as the case may be, execute and deliver

or cause to be executed and delivered all such

assignments and other instruments,  take or cause to be taken such actions, and

do or cause to be done all things reasonably necessary,  proper or advisable in
