                           Prospectus/Proxy Statement

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

   
                                                                  August  , 1998
    

     This Prospectus/Proxy Statement relates to the proposed merger (the
"Merger") of the Robertson Stephens Developing Countries Fund (the "Developing
Countries Fund"), a series of Robertson Stephens Investment Trust (the
"Trust"), into Robertson Stephens Partners Fund (the "Partners Fund"), another
series of the Trust. The Merger is to be effected through the transfer of all
of the assets of the Developing Countries Fund to the Partners Fund in exchange
for shares of beneficial interest of the Partners Fund (the "Merger Shares")
and the assumption by the Partners Fund of all of the liabilities of the
Developing Countries Fund, followed by the distribution of the Merger Shares to
the shareholders of the Developing Countries Fund in liquidation of the
Developing Countries Fund. As a result of the proposed Merger, each shareholder
of the Developing Countries Fund will receive in exchange for his or her
Developing Countries Fund shares a number of Partners Fund shares equal in
value at the date of the exchange to the aggregate value of the shareholder's
Developing Countries Fund shares.

     Because shareholders of the Developing Countries Fund are being asked to
approve a transaction which will result in their receiving shares of the
Partners Fund, this Proxy Statement also serves as a Prospectus for the Merger
Shares of the Partners Fund.

     The Partners Fund's investment objective is long-term growth. It pursues
this objective by employing a value methodology to invest in equity securities
primarily of companies with market capitalizations of up to $1 billion. The
Partners Fund is a "non-diversified" mutual fund.

     THIS PROSPECTUS/PROXY STATEMENT EXPLAINS CONCISELY WHAT YOU SHOULD KNOW
BEFORE INVESTING IN THE PARTNERS FUND. PLEASE READ IT AND KEEP IT FOR FUTURE
REFERENCE.

     This Prospectus/Proxy Statement is accompanied by a current Prospectus of
the Trust dated March 1, 1998 for the Fund's Class A or Class C Shares, as
amended or supplemented from time to time (each, a "Prospectus"). The
information regarding the Developing Countries Fund and the Partners Fund
contained in the Prospectus accompanying this Prospectus/Proxy Statement is
incorporated into this Prospectus/Proxy Statement by reference. Each of the
Developing Countries Fund and the Partners Fund is sometimes referred to in
this Prospectus/  Proxy Statement as a "Fund."

                            OVERVIEW OF THE MERGER

Proposed Transaction

     The Trustees of the Trust have unanimously approved an Agreement and Plan
of Reorganization between the Developing Countries Fund and the Partners Fund
(the "Agreement"), which is attached to this Prospectus/  Proxy statement as
Appendix A. Pursuant to the terms of the Agreement, the Developing Countries
Fund will receive a number of Class A and Class C shares of the Partners Fund
(the "Merger Shares") equal in value to the value of the net assets of the
Developing Countries Fund being transferred and attributable to the Class A and
Class C shares, respectively, of the Developing Countries Fund. Following the
transfer, (i) the Developing Countries Fund will distribute to each of its
Class A and Class C shareholders a number of full and fractional Class A and
Class C Merger Shares of the Partners Fund equal in value to the aggregate
value of that shareholder's Class A and/or Class C Developing Countries Fund
shares, as the case may be, and (ii) the Developing Countries Fund will be
liquidated.

   
     The Class A and Class C shares of the Partners Fund have substantially
identical characteristics to the corresponding classes of shares of the
Developing Countries Fund. Class A shares are sold at net asset value, without
an initial sales charge imposed by the Fund, and are subject to a distribution
fee at an annual rate of 0.25% of the average daily net assets attributable to
the Fund's Class A shares. (The Developing Countries Fund may make payments
under its Class A share distribution plan at an annual rate of up to 0.50% of
the Fund's average daily net assets; the Trustees have currently limited
payments under the plan to an annual rate of 0.25% of the Funds; average daily
net assets.) Class A shares are not subject to a contingent deferred sales
charge (a "CDSC"). Class C shares are sold at net asset value, without an
initial sales charge imposed by the Fund, but are subject to a 1.00% CDSC if
redeemed within one year after purchase. In addition, Class C shares of a Fund
are subject to a distribution fee at an annual rate of 0.75% of the average
daily net assets of the Fund attributable to its Class C shares. The Class C
Distribution Plan for each Fund permits payment under the Plan at an annual rate
of up to 1.00% of the Fund's average daily net assets attributable to its Class
C shares. The Class C shares of each Fund are also subject to a shareholder
servicing fee at an annual rate of 0.25% of the Fund's average daily net assets
attributable to its Class C shares. No CDSC will apply in connection with the
Merger. However, the Class C Merger Shares will be subject to a CDSC to the same
extent as were the Class C Developing Countries Fund shares in respect of which
they are issued. For the purposes of computing the CDSC, if any, payable on
redemption of Class C Merger Shares, the Merger Shares will be treated as having
been purchased as of the same date as the Class C Developing Countries Fund
shares in respect of which the Merger Shares were issued.


     [The Trustees unanimously recommend that shareholders of the Developing
Countries Fund approve the Merger because it offers shareholders the
opportunity to pursue a similar investment program in a larger fund, with
potentially reduced operating expenses. See "Operating Expenses" below and
"Approval or Disapproval of Agreement and Plan of Reorganization -- Background
and Reasons for the Proposed Merger."]

Operating Expenses

     The following tables summarize a shareholder's maximum transaction costs
from investing in shares of each Fund and expenses incurred by each Fund based
on its fiscal year ended December 31, 1997. The expenses shown for the Partners
Fund are based on the expenses the Partners Fund incurred in its fiscal year
ended December 31, 1997, but have been restated to give effect on a pro forma
combined basis to the proposed Merger, as if the Merger had occurred as of
January 1, 1998. Expenses shown for the Developing Countries Fund reflect an
expense limitation currently in effect; there is no assurance that the
limitation will continue in effect in the future. The tables are provided to
help explain a shareholder's share of the operating expenses which each Fund
incurs. The examples which follow show the estimated cumulative expenses
attributable to a hypothetical $1,000 investment in the Developing Countries
Fund and the Partners Fund, over specified periods.

     This information is provided to help investors understand the operating
expenses of the Funds. The example should not be considered a representation of
future performance. Actual expenses may be more or less than those shown. Other
Expenses and Total Fund Operating Expenses for the Developing Countries Fund
reflect voluntary expense limitations currently in effect. In the absence of
those limitations, Other Expenses and Total Fund Operating Expenses,
respectively, of the Developing Countries Fund would be 1.03% and 2.53% for the
Fund's Class A shares and 1.04% and 3.29% for the Fund's Class C shares. The
Management Fees paid by the Funds are higher than those paid by most other
mutual funds. Because of Rule 12b-1 fees paid by the Funds, long-term
shareholders may pay more than the economic equivalent of the maximum front-end
sales load permitted under applicable broker-dealer sales rules.

Federal Income Tax Consequences

     The Developing Countries Fund expects that the Merger will be a tax-free
reorganization for federal income tax purposes, and consequently that no gain
or loss will be recognized by the Developing Countries Fund or its shareholders
as a result of the Merger, and the tax basis of the Merger Shares received by
each Developing Countries Fund shareholder will be the same as the tax basis of
the shareholder's Developing Countries Fund shares. The Federal income tax
treatment of the Merger is not clear, however, and the Internal Revenue Service
may assert that the Merger is a taxable reorganization. If the Merger were
treated as a taxable event, the Developing Countries Fund would recognize gain
or loss on the sale of its assets to the Partners Fund, and shareholders of the
Developing Countries Fund would recognize taxable gain or loss on receipt of
the Merger Shares equal to the difference between the net asset value of the
Partners Fund shares received and the shareholder's tax basis in his or her
Developing Countries Fund shares. See "Information About the Merger -- Federal
Income Tax Consequences."

   
Comparison of Investment Objectives, Policies, and Restrictions
    

     Robertson Stephens Investment Management, L.P. ("RSIM") currently serves
as investment advisor to both Funds. The investment objectives, policies, and
restrictions of the Funds and certain differences between them are summarized
below. For a more detailed description of the investment techniques used by the
Funds, please see the accompanying Prospectus, as well as the SAI and the
Merger SAI.

     The Partners Fund's investment objective is long-term growth. The Partners
Fund employs a value methodology to invest in equity securities primarily of
companies with market capitalizations of up to $1 billion. This traditional
value methodology combines Graham & Dodd balance sheet analysis with cash flow
analysis. In selecting investments for the Partners Fund, RSIM: (i) performs
fundamental research focusing on business analysis; (ii) observes how
management allocates capital; (iii) strives to understand the unit economics of
the business of the company; (iv) keys on the cash flow rate of return on
capital employed; (v) discerns the sources and uses of cash; (vi) considers how
management is compensated; and (vii) asks how the stock market is pricing the
entire company. The Partners Fund may invest without limit in foreign
securities, and may, at times, invest all or most of its assets in securities
of U.S. issuers. See "Risk Factors -- Foreign securities," below.

     The Developing Countries Fund's investment objective is long-term capital
appreciation. The Developing Countries Fund invests primarily in a
non-diversified portfolio of publicly traded developing country equity
securities. The Developing Countries Fund may also, to a lesser degree, invest
in private placements of developing country equity securities. Developing
country equity securities are securities which are principally traded in the
capital markets of a developing country; securities of companies that derive at
least 50% of their total revenues from either goods produced or services
performed in developing countries or from sales made in developing countries,
regardless of where the securities of such companies are principally traded;
securities of companies organized under the laws of, and with a principal
office in, a developing country; securities of investment companies (such as
country funds) that principally invest in developing country securities; and
American Depository Receipts (ADRs) and Global Depository Receipts (GDRs) with
respect to the securities of such companies. Developing Countries are countries
that in the opinion of RSIM are generally considered to be developing countries
by the international financial community. Examples of countries that might
constitute developing countries


                                       6

<PAGE>

   
include: Argentina, Brazil, China, the Czech Republic, Egypt, Indonesia,
Israel, Korea, Malaysia, Mexico, Philippines, Romania, Russia, South Africa,
Taiwan, Thailand and Turkey. The Developing Countries Fund will normally invest
at least 65% of its assets in developing country equity securities. See "Risk
Factors -- Foreign Securities," below for a description of certain
characteristics of developing countries and related risks.

     In selecting investments for the Developing Countries Fund, RSIM may
consider a number of factors in evaluating potential investments, including
political risks, classic macroeconomic variables, and equity market valuations.
RSIM may also focus on the quality of a company's management, the company's
growth prospects, and the financial well being of the company. The Developing
Countries Fund's investments generally will reflect a broad cross-section of
countries, industries, and companies, in order to limit risk. In situations
where the market for a particular security is determined by RSIM to be
sufficiently liquid, the Developing Countries Fund may engage in short sales.
See "Risk Factors -- Short Sales," below for a discussion of certain
characteristics of short sales. The Developing Countries Fund may also borrow
money to purchase additional portfolio securities. See "Risk Factors --
Borrowing and Leverage," below for a discussion of certain characteristics of
such borrowing.
    

     The Developing Countries Fund may invest up to 10% of its total assets in
shares of other investment companies. Such other investment companies would
likely pay expenses similar to those paid by the Developing Countries Fund,
including, for example, advisory and administrative fees. RSIM will waive its
investment advisory fees on the Developing Countries Fund's assets invested in
other open-end investment companies, to the extent of the advisory fees of
those investment companies attributable to the Developing Countries Fund's
investment.

   
     Both Funds are non-diversified mutual funds, which entails certain risks.
See "Risk Factors -- Non-Diversification and Sector Concentration," below.
Although both Funds seek to invest principally in common stock, they may also
invest in preferred stocks, warrants, and debt securities if RSIM believes they
would help achieve the Fund's objective. Both Funds may also invest in options
and futures, index options and futures, and a variety of other derivative
instruments. See the Prospectus, the SAI, and the Merger SAI. See also "Risk
Factors -- Options and Futures," "Risk Factors -- Index Futures and Options,"
and "Risk Factors -- Risks Related to Options and Futures Strategies," below.
Both Funds invest in smaller companies, which may present greater opportunities
for investment return than do larger companies, but may also involve greater
risks. Such companies may have limited product lines, markets, or financial
resources, or may depend on a limited management group. Their securities may
trade less frequently and in limited volume. As a result, the prices of these
securities may fluctuate more than prices of securities of larger, more widely
traded companies. See "Risk Factors -- Investments in Smaller Companies," below.
    

     The Developing Countries Fund is managed by a team of professionals at
RSIM. Andrew P. Pilara, Jr., the President and Trustee of the Trust, is
primarily responsible for the day-to-day management of the Partners Fund.


Comparison of Distribution Policies and Purchase, Exchange, and Redemption
Procedures

     The Funds have substantially the same procedures for purchasing shares.
The Funds offer two classes of shares, Classes A and C, to the general public.
See "Overview of the Merger -- Proposed Transaction," above, for a description
of each Class.

     Shares of each Fund can be exchanged at net asset value for shares of the
same class of any other fund offered by the Trust, subject to certain
investment minimums and less any applicable CDSC.


                                       7

<PAGE>

     Redemption procedures for the Funds are also substantially identical.
Shares of a Fund may be redeemed on any day the New York Stock Exchange is open
at their net asset value next determined after receipt of the redemption
request, less any applicable CDSC. Shares can be redeemed through participating
financial institutions, by calling or submitting a written redemption request
directly to the Fund's transfer agent (for non-broker accounts) or through
Autosell (an automated system enabling electronic fund transfers to be made
directly between a shareholder's Fund account and bank account). Shares may
also be sold directly to a Fund by mail, by telephone or by wire transfer.


                                 RISK FACTORS

   
     Certain risks associated with an investment in the Partners Fund and of the
Developing Countries Fund are summarized below. The Partners Fund shares a
number of investment policies with the Developing Countries Fund as described
more fully above under "Overview of the Merger -- Comparison of Investment
Objectives, Policies, and Restrictions." Many of the risks of an investment in
the Partners Fund are substantially similar to the risks of an investment in the
Developing Countries Fund. A more detailed description of certain of the risks
associated with an investment in the Partners Fund may be found in the
Prospectus under the caption "Other Investment Practices and Risk
Considerations" and in the SAI.
    

     The values of all securities and other instruments held by the Partners
Fund vary from time to time in response to a wide variety of market factors.
Consequently, the net asset value per share of the Partners Fund will vary so
that an investor's shares, when redeemed, may be worth more or less than the
amount invested.

     Investments in Smaller Companies. Each Fund may invest a substantial
portion of its assets in securities issued by small companies. Such companies
may offer greater opportunities for capital appreciation than larger companies,
but investments in such companies may involve certain special risks. Such
companies may have limited product lines, markets, or financial resources and
may be dependent on a limited management group. While the markets in securities
of such companies have grown rapidly in recent years, such securities may trade
less frequently and in smaller volume than more widely held securities. The
values of these securities may fluctuate more sharply than those of other
securities, and a Fund may experience some difficulty in establishing or
closing out positions in these securities at prevailing market prices. There
may be less publicly available information about the issuers of these
securities or less market interest in such securities than in the case of
larger companies, and it may take a longer period of time for the prices of
such securities to reflect the full value of their issuers' underlying earnings
potential or assets.

     Some securities of smaller issuers may be restricted as to resale or may
otherwise be highly illiquid. The ability of a Fund to dispose of such
securities may be greatly limited, and a Fund may have to continue to hold such
securities during periods when RSIM would otherwise have sold the security. It
is possible that RSIM or its affiliates or clients may hold securities issued
by the same issuers, and may in some cases have acquired the securities at
different times, on more favorable terms, or at more favorable prices, than a
Fund.

     Short Sales. The Developing Countries Fund, but not the Partners Fund, may
engage in short sales on securities with a value of up to 25% of the Fund total
assets. When RSIM anticipates that the price of a security will decline, it may
sell the security short and borrow the same security from a broker or other
institution to complete the sale. The Developing Countries Fund may make a
profit or incur a loss depending upon whether the market price of the security
decreases or increases between the date of the short sale and the date on which
the Fund must replace the borrowed security. An increase in the value of a
security sold short by the Developing


                                       8

<PAGE>

Countries Fund over the price at which it was sold short will result in a loss
to the Fund, and there can be no assurance that the Fund will be able to close
out the position at any particular time or at an acceptable price. The Partners
Fund does not engage in short sales.

     Foreign Securities. Both Funds may invest in securities principally traded
in foreign markets. Because foreign securities are normally denominated and
traded in foreign currencies, the value of a Fund's assets may be affected
favorably or unfavorably by currency exchange rates and exchange control
regulations. There may be less information publicly available about a foreign
company than about a U.S. company, and foreign companies are not generally
subject to accounting, auditing, and financial reporting standards and
practices comparable to those in the United States. The securities of some
foreign companies are less liquid and at times more volatile than securities of
comparable U.S. companies. Foreign brokerage commissions and other fees are
also generally higher than in the United States. Foreign settlement procedures
and trade regulations may involve certain risks (such as delay in payment or
delivery of securities or in the recovery of a Fund's assets held abroad) and
expenses not present in the settlement of domestic investments.

     In addition, there may be a possibility of nationalization or
expropriation of assets, imposition of currency exchange controls, confiscatory
taxation, political or financial instability, and diplomatic developments that
could affect the value of a Fund's investments in certain foreign countries.
Legal remedies available to investors in certain foreign countries may be more
limited than those available with respect to investments in the United States
or in other foreign countries. In the case of securities issued by a foreign
governmental entity, the issuer may in certain circumstances be unable or
unwilling to meet its obligations on the securities in accordance with their
terms, and a Fund may have limited recourse available to it in the event of
default. The laws of some foreign countries may limit a Fund's ability to
invest in securities of certain issuers located in those foreign countries.
Special tax considerations apply to foreign securities. A Fund may buy or sell
foreign currencies and options and futures contracts on foreign currencies for
hedging purposes in connection with its foreign investments. Except as
otherwise provided in the Prospectus, there is no limit on the amount of a
Fund's assets that may be invested in foreign securities.

     Each of the Funds may invest in securities of issuers in developing
countries. Investments in developing countries are subject to the same risks
applicable to foreign investments generally, although those risks may be
increased due to conditions in such countries. For example, the securities
markets and legal systems in developing countries may only be in a
developmental stage and may provide few, or none, of the advantages or
protections of markets or legal systems available in more developed countries.
Although many of the securities in which the Funds may invest are traded on
securities exchanges, they may trade in limited volume, and the exchanges may
not provide all of the conveniences or protections provided by securities
exchanges in more developed markets. The Funds may also invest a substantial
portion of their assets in securities traded in the over-the-counter markets in
such countries and not on any exchange, which may affect the liquidity of the
investment and expose the Funds to the credit risk of their counterparties in
trading those investments. The prices of securities of issuers in developing
countries are subject to greater volatility than those of issuers in many more
developed countries.

     Debt Securities. Each of the Funds may invest in debt securities from time
to time, if RSIM believes investing in such securities might help achieve the
Fund's objective. The Partners Fund may invest without limit in debt securities
and other fixed-income securities. The Developing Countries Fund may invest in
debt securities to the extent consistent with its investment policies, although
RSIM expects that under normal circumstances the Developing Countries Fund
would not likely invest a substantial portion of its assets in debt securities.



                                       9

<PAGE>

     The Funds will invest only in securities rated "investment grade" or
considered by RSIM to be of comparable quality. Investment grade securities are
rated Baa or higher by Moody's Investors Service, Inc. or BBB or higher by
Standard & Poor's. Securities rated Baa or BBB lack outstanding investment
characteristics, have speculative characteristics, and are subject to greater
credit and market risks than higher-rated securities. Descriptions of the
securities ratings assigned by Moody's and Standard & Poor's are set out in the
SAI.

     Both Funds may at times invest in so-called "zero-coupon" bonds and
"payment-in-kind" bonds. Zero-coupon bonds are issued at a significant discount
from face value and pay interest only at maturity rather than at intervals
during the life of the security. Payment-in-kind bonds allow the issuer, at its
option, to make current interest payments on the bonds either in cash or in
additional bonds. The values of zero-coupon bonds and payment-in-kind bonds are
subject to greater fluctuation in response to changes in market interest rates
than bonds which pay interest currently, and may involve greater credit risk
than such bonds.

     A Fund will not necessarily dispose of a security when its debt rating is
reduced below its rating at the time of purchase, although RSIM will monitor
the investment to determine whether continued investment in the security will
assist in meeting the Fund's investment objective. If a security's rating is
reduced below investment grade, an investment in that security may entail the
risks of lower-rated securities described below:

     Borrowing and leverage. The Developing Countries Fund may borrow money to
invest in additional portfolio securities. This practice, known as "leverage,"
increases the Fund's market exposure and its risk. In addition, use of short
sales by the Developing Countries Fund may provide the economic equivalent of
the Fund's borrowing money. When the Fund has borrowed money for leverage and
its investments increase or decrease in value, the Fund's net asset value will
normally increase or decrease more than if it had not borrowed money. The
interest the Fund must pay on borrowed money will reduce the amount of any
potential gains or increase any losses. The extent to which the Developing
Countries Fund will borrow money, and the amount it may borrow, depend on
market conditions and interest rates. Successful use of leverage depends on
RSIM's ability to predict market movements correctly. The Developing Countries
Fund may at times borrow money by means of reverse repurchase agreements.
Reverse repurchase agreements generally involve the sale by a Fund of
securities held by it and an agreement to repurchase the securities at an
agreed-upon price, date, and interest payment. Reverse repurchase agreements
will increase a Fund's overall investment exposure and may result in losses.
The amount of money borrowed by the Developing Countries Fund for leverage may
generally not exceed one-third of the Fund's assets (including the amount
borrowed).

     Options and Futures. Both Funds may buy and sell call and put options to
hedge against changes in net asset value or to attempt to realize a greater
current return. In addition, through the purchase and sale of futures contracts
and related options, a Fund may at times seek to hedge against fluctuations in
net asset value and to attempt to increase its investment return.

     A Fund's ability to engage in options and futures strategies will depend
on the availability of liquid markets in such instruments. It is impossible to
predict the amount of trading interest that may exist in various types of
options or futures contracts. Therefore, there is no assurance that a Fund will
be able to utilize these instruments effectively for the purposes stated above.
Options and futures transactions involve certain risks which are described
below and in the SAI.

     Transactions in options and futures contracts involve brokerage costs and
may require a Fund to segregate assets to cover its outstanding positions. For
more information, see the SAI.


                                       10

<PAGE>

     Index Futures and Options. The Funds may buy and sell index futures
contracts ("index futures") and options on index futures and on indices (or may
purchase investments whose values are based on the value from time to time of
one or more securities indices) for hedging purposes. An index future is a
contract to buy or sell units of a particular bond or stock index at an agreed
price on a specified future date. Depending on the change in value of the index
between the time when the Fund enters into and terminates an index futures or
option transaction, the Fund realizes a gain or loss. A Fund may also buy and
sell index futures and options to increase its investment return.

     Risks Related to Options and Futures Strategies. Options and futures
transactions involve costs and may result in losses. Certain risks arise
because of the possibility of imperfect correlations between movements in the
prices of futures and options and movements in the prices of the underlying
security or index of the securities held by a Fund that are the subject of a
hedge. The successful use by a Fund of the strategies described above further
depends on the ability of RSIM to forecast market movements correctly. Other
risks arise from a Fund's potential inability to close out futures or options
positions. Although a Fund will enter into options or futures transactions only
if RSIM believes that a liquid secondary market exists for such option or
futures contract, there can be no assurance that a Fund will be able to effect
closing transactions at any particular time or at an acceptable price.

     Each Fund expects that its options and futures transactions generally will
be conducted on recognized exchanges. A Fund may in certain instances purchase
and sell options in the over-the-counter markets. A Fund's ability to terminate
options in the over-the-counter markets may be more limited than for
exchange-traded options, and such transactions also involve the risk that
securities dealers participating in such transactions would be unable to meet
their obligations to the Fund. A Fund will, however, engage in over-the-counter
transactions only when appropriate exchange-traded transactions are unavailable
and when, in the opinion of RSIM, the pricing mechanism and liquidity of the
over-the-counter markets are satisfactory and the participants are responsible
parties likely to meet their obligations.

     A Fund will not purchase futures or options on futures or sell futures if,
as a result, the sum of the initial margin deposits on the Fund's existing
futures positions and premiums paid for outstanding options on futures
contracts would exceed 5% of the Fund's assets. (For options that are
"in-the-money" at the time of purchase, the amount by which the option is
"in-the-money" is excluded from this calculation.)

   
     Non-Diversification and Sector Concentration. The Partners Fund and the
Developing Countries Fund are "non-diversified" investment companies, and each
may invest its assets in a more limited number of issuers than may other
investment companies. Under the Internal Revenue Code, an investment company,
including a non-diversified investment company, generally may not invest more
than 25% of its assets in obligations of any one issuer other than U.S.
Government obligations and, with respect to 50% of its total assets, a Fund may
not invest more than 5% of its total assets in the securities of any one issuer
(except U.S. Government securities). Thus, each Fund may invest up to 25% of
its total assets in the securities of each of any two issuers. This practice
involves an increased risk of loss to the Fund if the market value of a
security should decline or its issuer were otherwise not to meet its
obligations.
    

     At times a Fund may invest more than 25% of its assets in securities of
issuers in one or more market sectors such as, for example, the technology
sector. A market sector may be made up of companies in a number of related
industries. A Fund would only concentrate its investments in a particular
market sector if RSIM were to believe the investment return available from
concentration in that sector justifies any additional risk associated


                                       11

<PAGE>

with concentration in that sector. When a Fund concentrates its investments in
a market sector, financial, economic, business, and other developments
affecting issuers in that sector will have a greater effect on the Fund than if
it had not concentrated its assets in that sector.

     Securities Loans and Repurchase Agreements. Both Funds may lend portfolio
securities to broker-dealers and may enter into repurchase agreements. These
transactions must be fully collateralized at all times, but involve some risk
to a Fund if the other party should default on its obligations and the Fund is
delayed or prevented from recovering the collateral.

     Defensive Strategies. At times, RSIM may judge that market conditions make
pursuing a Fund's basic investment strategy inconsistent with the best
interests of its shareholders. At such times, RSIM may temporarily use
alternative strategies, primarily designed to reduce fluctuations in the values
of the Fund's assets. In implementing these "defensive" strategies, a Fund may
invest in U.S. Government securities, other high-quality debt instruments, and
other securities RSIM believes to be consistent with the Fund's best interests.

     Portfolio Turnover. The length of time a Fund has held a particular
security is not generally a consideration in investment decisions. The
investment policies of a Fund may lead to frequent changes in the Fund's
investments, particularly in periods of volatile market movements. A change in
the securities held by a Fund is known as "portfolio turnover." Portfolio
turnover generally involves some expense to a Fund, including brokerage
commissions or dealer mark-ups and other transaction costs on the sale of
securities and reinvestment in other securities. Such sales may result in
realization of taxable capital gains. The portfolio turnover rate for the
Developing Countries Fund during its fiscal year ended December 31, 1997 was
148% and the rate for the Partners Fund for the year was 78%.


                            MEETING OF SHAREHOLDERS

   
     This Prospectus/Proxy Statement is furnished in connection with a meeting
of Developing Countries Fund shareholders to be held on August   , 1998 or at
such later time as may be made necessary by adjournment (the "Meeting"), and
the solicitation of proxies by and on behalf of the Board of Trustees of the
Trust for use at the Meeting. The Meeting is being held to consider the
proposed Merger of the Developing Countries Fund and the Partners Fund by the
transfer of all of the Developing Countries Fund's assets and liabilities to
the Partners Fund. This Prospectus/Proxy Statement and the enclosed form of
proxy are being mailed to shareholders on or about August   , 1998.
    

     The Board of Trustees of the Trust knows of no matters other than those
set forth herein to be brought before the Meeting. If, however, any other
matters properly come before the Meeting, it is the Board's intention that
proxies will be voted on such matters in accordance with the judgment of the
persons named in the enclosed form of proxy.


        APPROVAL OR DISAPPROVAL OF AGREEMENT AND PLAN OF REORGANIZATION

Summary of Proposal

     The shareholders of the Developing Countries Fund are being asked to
approve or disapprove the Merger between the Developing Countries Fund and the
Partners Fund. The Merger is proposed to take place pursuant to the Agreement
and Plan of Reorganization between the Developing Countries Fund and the
Partners Fund (the "Agreement"), the form of which is attached to this
Prospectus/Proxy Statement as Appendix A.


                                       12

<PAGE>

     The Agreement provides, among other things, for the transfer of all of the
assets of the Developing Countries Fund to the Partners Fund in exchange for
(i) the assumption by the Partners Fund of all of the liabilities of the
Developing Countries Fund and (ii) the issuance to the Developing Countries
Fund of the Class A and Class C Merger Shares, the number of which will be
calculated based upon the value of the net assets attributable to the Class A
and Class C shares, respectively, of the Developing Countries Fund acquired by
the Partners Fund and the net asset value per Class A and Class C share of the
Partners Fund, all as more fully described below under "Information About the
Merger."

     After receipt of the Merger Shares, the Developing Countries Fund will
cause the Class A Merger Shares to be distributed to its Class A shareholders
and the Class C Merger Shares to be distributed to its Class C shareholders in
complete liquidation of the Developing Countries Fund. Each shareholder of the
Developing Countries Fund will receive a number of full and fractional Class A
or Class C Merger Shares equal in value at the date of the exchange to the
aggregate value of the shareholder's Class A or Class C Developing Countries
Fund shares, as the case may be.

   
     Trustees' Recommendation. [The Trustees of the Trust have voted unanimously
to approve the proposed Merger by and between the Developing Countries Fund and
the Partners Fund and to recommend that shareholders of the Developing Countries
Fund also approve the Merger for such Fund.]
    

   
     Required Shareholder Vote. Approval of the proposed Merger will require
the affirmative vote of a majority of the shares of the Developing Countries
Fund voted at the Meeting if a quorum is present. Shares of the Developing
Countries Fund shall vote together as a single class.
    

     A shareholder of the Developing Countries Fund objecting to the proposed
Merger is not entitled under either Massachusetts law or the Trust's Agreement
and Declaration of Trust (the "Declaration of Trust") to demand payment for or
an appraisal of his or her Developing Countries Fund shares if the Merger is
consummated over his or her objection. Shareholders may, however, redeem their
shares at any time prior to the Merger, and if the Merger is consummated,
shareholders will still be free at any time to redeem their Merger Shares, in
each case for cash at net asset value at the time of such redemption, less any
applicable CDSC, or to exchange their Merger Shares for shares of the same
class of other funds offered by the Trust.


Background and Reasons for the Proposed Merger

   
     [The Trustees of the Trust, including the Trustees who are not "interested
persons" of the Trust within the meaning of the Investment Company Act of 1940,
as amended (the "Independent Trustees"), have determined that the Merger would
be in the best interests of each Fund, and that the interests of each Fund's
shareholders would not be diluted as a result of effecting the Merger. In
evaluating the proposed Merger, the Trustees considered the investment
objectives and policies, the asset sizes, the fee structures, and the operating
histories of both Funds. The Trustees also consulted with RSIM concerning the
anticipated impact that the Merger would have on the Funds and their
shareholders with respect to a variety of factors, including tax considerations.
In addition, the Trustees considered that the Developing Countries Fund had
experienced significant redemptions during the past year, and that, in light of
its investment policies and its investment performance to date, the Fund was
unlikely under current market conditions to experience any substantial increase
in its size.]
    

     [The principal reasons why the Trustees are recommending the Merger are as
follows:

   
     Economies of Scale at Fund Level. The Trustees have determined that it is
in the best interests of the Developing Countries Fund's shareholders to
combine the Developing Countries Fund with the Partners Fund in order
    

                                       13

<PAGE>

to increase the asset base over which the Developing Countries Fund's expenses
will be spread. The increased asset base is expected to result in aggregate
operating expenses that would be lower than those that would otherwise be borne
by the Developing Countries Fund.

       

   
     Appropriate Investment Objectives. The Trustees considered that, in light
of the Developing Countries Fund's performance to date and the fact that the
Fund was unlikely to experience any substantial increase in size under current
market conditions, the Partners Fund may provide a desirable alternative
investment opportunity for Developing Countries shareholders. The Trustees
considered that, although the Partners Fund is not required to invest any
portion of its assets in developing countries, it nonetheless provides investors
with a long-term investment in a portfolio of equity securities selected by RSIM
based on fundamental analysis, with the capability to invest any part of its
assets in foreign countries, including developing countries. (Under current
market conditions, most of the Partners Fund's assets are invested in securities
of issuers located in the United States.) The Trustees also considered that,
although the Developing Countries Fund is not required to invest in securities
of smaller companies, it has typically invested a substantial portion of its
assets in companies with market capitalizations of less than $1 billion. (The
Partners Fund invests in equity securities primarily of companies with market
capitalizations of up to $1 billion.)]
    

Information about the Merger

     Agreement and Plan of Reorganization. The proposed Agreement provides that
the Partners Fund will acquire all of the assets of the Developing Countries
Fund in exchange for (i) the assumption by the Partners Fund of all of the
liabilities of the Developing Countries Fund and (ii) the issuance of the Class
A and Class C Merger Shares, all as of the Exchange Date (defined in the
Agreement to be August   , 1998 or such other date as may be agreed upon by the
Funds). The following discussion of the Agreement is qualified in its entirety
by the full text of the Agreement, the form of which is attached as Appendix A
to this Prospectus/Proxy Statement.

     The Developing Countries Fund will transfer all of its assets to the
Partners Fund. In exchange, the Partners Fund will assume all of the
liabilities of the Developing Countries Fund and deliver to the Developing
Countries Fund (i) a number of full and fractional Class A Merger Shares having
an aggregate net asset value equal to the value of the assets of the Developing
Countries Fund attributable to its Class A shares, less the value of the
liabilities of the Developing Countries Fund assumed by the Partners Fund
attributable to the Class A shares of the Developing Countries Fund, and (ii) a
number of full and fractional Class C Merger Shares having an aggregate net
asset value equal to the value of the assets of the Developing Countries Fund
attributable to its Class C shares, less the value of the liabilities of the
Developing Countries Fund assumed by the Partners Fund attributable to the
Class C shares of the Developing Countries Fund.

     Immediately following the Exchange Date, the Developing Countries Fund
will distribute pro rata to its shareholders of record as of the close of
business on the Exchange Date the full and fractional Merger Shares received by
the Developing Countries Fund, with Class A Merger Shares being distributed to
holders of Class A shares of the Developing Countries Fund and Class C Merger
Shares being distributed to holders of


                                       14

<PAGE>

   
Class C shares of the Developing Countries Fund. As a result of the proposed
transaction, each holder of Class A and Class C shares of the Developing
Countries Fund will receive a number of Class A and Class C Merger Shares equal
in aggregate value at the Exchange Date to the value of the Class A and Class C
shares, respectively, of the Developing Countries Fund held by the shareholder.
This distribution will be accomplished by the establishment of accounts on the
share records of the Partners Fund in the names of the Developing Countries
Fund shareholders, each account representing the number of full and fractional
Class A and Class C Merger Shares due such shareholder. Certificates for Merger
Shares will not be issued.
    

     The consummation of the Merger is subject to the conditions set forth in
the Agreement, any of which may be waived. The Agreement may be terminated and
the Merger abandoned at any time before or after approval by the shareholders
of the Developing Countries Fund, prior to the Exchange Date, by mutual consent
of the Funds or, if any condition set forth in the Agreement has not been
fulfilled and has not been waived by the party entitled to its benefits, by
such party. The Agreement provides that the Merger need not be consummated if
the Trustees of the Trust shall have concluded in good faith, prior to the
Exchange Date, that the Merger would not be in the best interests of the
Developing Countries Fund's shareholders.

     All legal and accounting fees and expenses, printing, filing and proxy
solicitation expenses, portfolio transfer taxes (if any), brokerage and similar
expenses and other fees and expenses incurred in connection with the
consummation of the transactions contemplated by the Agreement will be borne by
the Developing Countries Fund and the Partners Fund in the same proportions as
their respective aggregate net asset values bear to each other.

     Notwithstanding any of the foregoing, expenses will in any event be paid
by the party directly incurring such expenses if and to the extent that the
payment by any other party of such expenses would result in the
disqualification of the first party as a "regulated investment company" within
the meaning of Section 851 of the Internal Revenue Code of 1986, as amended
(the "Code").

   
     Description of the Merger Shares. Full and fractional Merger Shares will be
issued to the Developing Countries Fund's shareholders in accordance with the
procedure under the Agreement as described above. The Merger Shares are Class A
and Class C shares of the Partners Fund, which have characteristics
substantially identical to those of the corresponding class of the Developing
Countries Fund with respect to sales charges, CDSCs, and Rule 12b-1 fees, and
shareholder servicing fees.
    

     The Partners Fund and the Developing Countries Fund each pays a management
fee at an annual rate of 1.25% of average daily net assets.

     Class A shares of the Partners Fund are sold at net asset value, without an
initial sales charge imposed by the Fund, and are subject to a distribution fee
at an annual rate of 0.25% of the Fund's average daily net assets attributable
to its Class A shares. (The Developing Countries Fund may make payments under
its Class A shares distribution plan at an annual rate of up to 0.50% of the
Fund's average daily net assets; the Trustees have currently limited payments
under the plan to an annual rate of 0.25% of the Fund's average daily net
assets.) Class A shares are not subject to a CDSC. Class C shares of the
Partners Fund are sold at net asset value, without an initial sales charge
imposed by the Fund, but are subject to a 1.00% CDSC if redeemed within one year
after purchase. In addition, Class C shares of the Partners Fund are subject to
a distribution fee paid by the Fund at an annual rate of 0.75% of the average
daily net assets of the Fund attributable to its Class C shares. The
Distribution Plan relating to the Fund's Class C shares permits payment under
the Plan at an annual rate of up to 1.00% of the average daily net assets of the
Fund attributable to the Fund's Class C shares. The Class C shares of the Fund
are also subject to a shareholder servicing fee at an annual rate of 0.25% of
the average daily net assets of the Fund attributable to its Class C shares.
Class C shares of the


                                       15

<PAGE>

Partners Fund are subject to a 1.00% CDSC if redeemed within one year after
purchase. Shareholders redeeming Class C shares have a one-time right, however,
to reinvest within 90 days the redemption proceeds plus the CDSC paid, if any,
at the next determined net asset value. For the purposes of computing the CDSC,
if any, payable on redemption of Class C Merger Shares, the Merger Shares will
be treated as having been purchased as of the date that, and for the price at
which, the Class C Developing Countries Fund shares exchanged for such Merger
Shares were purchased.

     Both Class A and Class C shares of the Partners Fund are subject to a
$9.00 fee charged for redemptions made by bank wire. In addition, shares of
both classes of the Partners Fund can be exchanged at net asset value for
shares of the same class of any other fund offered by the Trust, subject to
certain limitations set forth in the Prospectus.

        

   
     Federal Income Tax Consequences. The Merger is expected to be a tax-free
reorganization, in which case (i) under Section 361 of the Code, no gain or
loss will be recognized by the Developing Countries Fund as a result of the
reorganization; (ii) under Section 354 of the Code, no gain or loss will be
recognized by shareholders of the Developing Countries Fund on the distribution
of Merger Shares to them in exchange for their shares of the Developing
Countries Fund; (iii) under Section 358 of the Code, the tax basis of the
Merger Shares that the Developing Countries Fund's shareholders receive in
place of their Developing Countries Fund shares will be the same as the basis
of the Developing Countries Fund shares exchanged; (iv) under Section 1223(1)
of the Code, a shareholder's holding period for the Merger Shares received
pursuant to the Agreement will be determined by including the holding period
for the Developing Countries Fund shares exchanged for the Merger Shares,
provided that the shareholder held the Developing Countries Fund shares as a
capital asset; (v) under Section 1032 of the Code, no gain or loss will be
recognized by the Partners Fund as a result of the reorganization; (vi) under
Section 362(b) of the Code, the Partners Fund's tax basis in the assets that
the Partners Fund receives from the Developing Countries Fund will be the same
as the Developing Countries Fund's basis in such assets; and (vii) under
Section 1223(2) of the Code, the Partners Fund's holding period in such assets
will include the Developing Countries Fund's holding period in such assets. The
treatment of the Merger as a tax-free reorganization is based in part on the
circumstances prevailing at the time of the Merger.
    

     The federal income tax treatment of the Merger is not clear, however, and
the Internal Revenue Service may assert that the Merger is a taxable
reorganization. If the Merger were treated as a taxable event, the Developing
Countries Fund would recognize gain or loss on the sale of its assets to the
Partners Fund, and shareholders of the Developing Countries Fund would
recognize taxable gain or loss on receipt of the Merger Shares equal to the
difference between the net asset value of the Partners Fund shares received and
the shareholder's tax basis in his or her Developing Countries Fund shares. In
particular, in such a case, the Partners Fund's cost basis for each security
acquired from the Developing Countries Fund in the Merger would be the fair
market value of such


                                       16

<PAGE>

security at the time of the Merger (rather than the Developing Countries Fund's
cost basis), and as a result of the Merger the Developing Countries Fund's net
unrealized losses and capital loss carryforwards would not be available for use
by either Fund. In addition, "individuals" (as defined in the Code) would be
able to use any capital losses arising from the Merger to offset other realized
capital gains or to offset ordinary income in the current year up to $3,000,
and would also be able carry forward losses indefinitely to offset future
realized capital gains, and shareholders who are not "individuals" would be
able to use realized capital losses to offset realized capital gains in the
current year and would also be able to carry forward or carry back losses to
offset future or past realized gains. There can be no assurance that the
Internal Revenue Service would not prevail in the assertion that the Merger is
a taxable transaction.

     Because the Developing Countries Fund's belief that the reorganization
will be tax-free is based in part on certain factors beyond its control and
which cannot yet be determined (including in particular shareholder redemption
levels prior to the Merger), it is possible that the Developing Countries Fund
itself will take the position that the reorganization is taxable. You should
consult your tax adviser as to your precise tax consequences arising from the
Merger. To receive a written summary of your investment history call the Funds
at 1-800-766-FUND.

     At July    , 1998, the Developing Countries Fund had an unrealized capital
loss of approximately       , or approximately     per Class A and Class C
share of that Fund. As of the same date, the Partners Fund had an unrealized
capital gain of approximately         or approximately      per Class A share
and     per Class C share. If the Merger had been effected at that date, the
unrealized capital gain per Class A share of the Partners Fund (including Class
A Merger Shares) would have been approximately     per share, and the
unrealized capital gain per Class C share of the Partners Fund (including Class
C Merger Shares) would have been approximately     per share. At December 31,
1997, the Developing Countries Fund had a tax loss carryforward of
approximately           .

     Declaration of Trust. Each of the Merger Shares will be fully paid and
nonassessable by the Partners Fund when issued, will be transferable without
restriction, and will have no preemptive or conversion rights.

     Under Massachusetts law, shareholders of a Massachusetts business trust
could, under certain circumstances, be held personally liable for the
obligations of the trust. However, the Declaration of Trust disclaims
shareholder liability for claims against the Trust and contemplates that notice
of such disclaimer be given in any note, bond, contract, instrument,
certificate, or undertaking made or issued on behalf of the Trust or the Board
of Trustees. The Declaration of Trust provides for indemnification out of the
Trust property for all loss and expense of any shareholder held personally
liable solely by reason of his or her being or having been a shareholder. Thus,
the risk of a shareholder's incurring financial loss from shareholder liability
is limited to circumstances in which the Trust would be unable to meet its
obligations. The likelihood of such a circumstance is considered remote. The
shareholders of the Developing Countries Fund are currently subject to the same
risk of shareholder liability under Massachusetts law and the Declaration of
Trust.

     A Trustee may be removed from office by vote of shareholders holding at
least two-thirds of the outstanding shares of the Trust.

     The Declaration of Trust provides that any fund, including the Developing
Countries Fund, may be terminated at any time by the affirmative vote of a
"majority of the outstanding voting securities" of that fund (as the quoted
phrase is defined in the 1940 Act) or by the Trustees by written notice to the
shareholders of that fund. The Declaration of Trust provides that the Trust may
be terminated at any time by the affirmative vote of a


                                       17

<PAGE>

"majority of the outstanding voting securities" of each series of the Trust (as
the quoted phrase is defined in the 1940 Act), voting separately by series, or
by the Trustees by written notice to the shareholders of the Trust.

     The Declaration of Trust provides that 40% of the shares entitled to vote
at the Meeting will constitute a quorum for the Meeting.

     Capitalization. The following table shows the capitalizations of the
Partners Fund and the Developing Countries Fund as of December 31, 1997 and of
the Partners Fund on a pro forma basis as of that date, giving effect to the
proposed acquisition by the Partners Fund of the assets and liabilities of the
Developing Countries Fund at net asset value:

                              VOTING INFORMATION

     Record Date, Quorum, and Method of Tabulation. Shareholders of record of
the Developing Countries Fund at the close of business on July   , 1998 (the
"Record Date") will be entitled to notice of and to vote at the Meeting or any
adjournment thereof. The holders of 40% of the Class A and Class C shares of
the Developing Countries Fund outstanding at the close of business on the
Record Date present in person or represented by proxy will constitute a quorum
for the Meeting. Shareholders are entitled to one vote for each share held,
with fractional shares voting proportionally. Only shareholders of the
Developing Countries Fund will vote on the approval or disapproval of the
Merger.

     Votes cast by proxy or in person at the Meeting will be counted by persons
appointed by the Trust to act as tellers for the Meeting. The tellers will
count the total number of votes cast "for" approval of the proposal for
purposes of determining whether sufficient affirmative votes have been cast.
The tellers will count shares represented by proxies that withold authority to
vote or that reflect abstentions or "broker non-votes" (i.e., shares held by a
broker or nominee as to which (i) instructions have not been received from the
beneficial owners or the persons entitled to vote and (ii) the broker or
nominee does not have the discretionary voting power on a particular matter) as
shares that are present and entitled to vote on the matter for purposes of
determining the presence of a quorum. Abstentions and broker non-votes will
have no effect on the proposal to approve the Merger.

     Other Business.The Board of Trustees knows of no other business to be
brought before the Meeting. However, if any other matters properly come before
the Meeting, it is the Board's intention that proxies which do not contain
specific restrictions to the contrary will be voted on such matters in
accordance with the judgment of the persons named as proxies in the enclosed
form of proxy.

     Shares Outstanding and Beneficial Ownership. As of the Record Date, as
shown on the books of the Trust, there were issued and outstanding
Class A shares and           Class C shares of the Developing Countries Fund.

     As of the Record Date, the officers and Trustees of the Trust as a group

     Solicitation of Proxies. The costs of solicitation of proxies will be
borne by the Developing Countries Fund and the Partners Fund in the same
proportions as their respective aggregate net asset values bear to each other.


                                       20

<PAGE>

Solicitation of proxies by personal interview, mail, telephone, and telegraph
may be made by officers and Trustees of the Trust and employees of RSIM and its
affiliates (who will receive no compensation therefor in addition to their
regular salaries).

     The Trust may also arrange to have votes recorded by telephone. The
telephone voting procedure is designed to authenticate shareholders'
identities, to allow shareholders to authorize the voting of their shares in
accordance with their instructions, and to confirm that their instructions have
been properly recorded. The Trust has been advised by counsel that these
procedures are consistent with the requirements of applicable law. If these
procedures were subject to a successful legal challenge, such votes would not
be counted at the Meeting. The Trust is unaware of any such challenge at this
time. Shareholders would be called at the phone number the Trust (or a
shareholder's financial institution) has in its records for their accounts, and
would be asked for their Social Security number or other identifying
information. The shareholders would then be given an opportunity to authorize
proxies to vote their shares at the Meeting in accordance with their
instructions. To ensure that the shareholders' instructions have been recorded
correctly, they will also receive a confirmation of their instructions in the
mail. A special toll-free number will be available in case the information
contained in the information is incorrect.

     Revocation of Proxies. Any shareholder giving a proxy has the power to
revoke it at any time before it is exercised by sending or delivering a written
revocation to the Secretary of the Trust (which will be effective when it is
received by the Secretary), by properly executing a later-dated proxy, or by
attending the Meeting, requesting return of such proxy, and voting in person.
All properly executed proxies received in time for the Meeting will be voted in
accordance with the specification made, or, if no specification is made, FOR
the proposal to implement the Merger.

     Shareholder Proposals at Future Meetings of Shareholders. The Declaration
of Trust does not provide for annual meetings of shareholders, and the Trust
does not currently intend to hold such a meeting in 1998. Shareholder proposals
for inclusion in a proxy statement for any subsequent meeting of the Trust's
shareholders must be received by the Trust a reasonable period of time prior to
any such meeting. If the Merger is consummated, the Developing Countries Fund's
existence will terminate in August   , 1998 or shortly thereafter, after which
there would be no meetings of the shareholders of the Developing Countries Fund


     Adjournment. In the event that sufficient votes in favor of the Merger
proposal are not received by the time scheduled for the Meeting, the persons
named as proxies may propose one or more adjournments of the Meeting for a
period or periods of not more than 60 days in the aggregate to permit further
solicitation of proxies. In addition, if, in the judgment of the persons named
as proxies, subsequent developments make it advisable to defer action on the
Merger, the persons named as proxies may propose one or more adjournments of
the Meeting for a reasonable period of time in order to defer action of the
Merger. Any adjournment will require the affirmative vote of a majority of the
votes cast on the question in person or by proxy at the session of the Meeting
to be adjourned. The persons named as proxies will vote in favor of such
adjournment those proxies which they are entitled to vote in favor of the
Merger. They will vote against any such adjournment those proxies which they
have been instructed to vote against the Merger, and they will vote to abstain
any such proxies which they are required to abstain from voting on the Merger.
The costs of any such additional solicitation and of any adjourned session will
be borne by the Developing Countries Fund and the Partners Fund in the same
proportions as their respective aggregate net asset values bear to each other.

                 FORM OF AGREEMENT AND PLAN OF REORGANIZATION

     This Agreement and Plan or Reorganization (the "Agreement") is made as of
July   , 1998 in San Francisco, California, by and between Robertson Stephens
Investment Trust, a Massachusetts business trust (the "Robertson Stephens
Trust"), on behalf of its Robertson Stephens Developing Countries Fund series
(the "Acquired Fund"), and the Robertson Stephens Trust, on behalf of its
Robertson Stephens Partners Fund series (the "Acquiring Fund").


Plan of Reorganization

     (a) The Acquired Fund will sell, assign, convey, transfer, and deliver to
the Acquiring Fund on the Exchange Date (as defined in Section 6) all of its
properties and assets. In consideration therefor, the Acquiring Fund will, on
the Exchange Date, assume all of the liabilities of the Acquired Fund existing
at the Valuation Time (as defined in Section 3(c)) and deliver to the Acquired
Fund (i) a number of full and fractional Class A shares of beneficial interest
of the Acquiring Fund (the "Class A Merger Shares") having an aggregate net
asset value equal to the value of the assets of the Acquired Fund attributable
to Class A shares of the Acquired Fund transferred to the Acquiring Fund on
such date less the value of the liabilities of the Acquired Fund attributable
to Class A shares of the Acquired Fund assumed by the Acquiring Fund on that
date, and (ii) a number of full and fractional Class C shares of beneficial
interest of the Acquiring Fund (the "Class C Merger Shares") having an
aggregate net asset value equal to the value of the assets of the Acquired Fund
attributable to Class C shares of the Acquired Fund transferred to the
Acquiring Fund on such date less the value of the liabilities of the Acquired
Fund attributable to Class C shares of the Acquired Fund assumed by the
Acquiring Fund on that date. (The Class A Merger Shares and the Class C Merger
Shares are referred to collectively herein as the "Merger Shares.")

     (b) Upon consummation of the transactions described in paragraph (a) of
this Agreement, the Acquired Fund shall distribute in complete liquidation to
its Class A and Class C shareholders of record as of the Exchange Date the
Class A and Class C Merger Shares of the Acquiring Fund, each such shareholder
being entitled to receive that proportion of such Class A and Class C Merger
Shares which the number of Class A and Class C shares of beneficial interest of
the Acquired Fund held by such shareholder bears to the number of Class A and
Class C shares of the Acquired Fund outstanding on such date. Certificates
representing the Merger Shares will not be issued. All issued and outstanding
shares of the Acquired Fund will simultaneously be canceled on the books of the
Acquired Fund.

     (c) As promptly as practicable after the liquidation of the Acquired Fund
as aforesaid, the Acquired Fund shall be dissolved pursuant to the provisions
of the Agreement and Declaration of Trust of the Robertson Stephens Trust, as
amended, and applicable law, and its legal existence terminated. Any reporting
responsibility of the Acquired Fund is and shall remain the responsibility of
the Acquired Fund up to and including the Exchange Date and, if applicable,
such later date on which the Acquired Fund is liquidated.


Agreement

     The Acquiring Fund and the Acquired Fund agree as follows:

     1. Representations, Warranties, and Agreements of the Acquiring Fund. The
Acquiring Fund represents and warrants to and agrees with the Acquired Fund
that:


                                      A-1

<PAGE>

       a. The Acquiring Fund is a series of shares of the Robertson Stephens
   Trust, a Massachusetts business trust duly established and validly existing
   under the laws of The Commonwealth of Massachusetts, and has power to own
   all of its properties and assets and to carry out its obligations under
   this Agreement. The Robertson Stephens Trust is qualified as a foreign
   association in every jurisdiction where required, except to the extent that
   failure so to qualify would not have a material adverse effect on the
   Robertson Stephens Trust. Each of the Robertson Stephens Trust and the
   Acquiring Fund has all necessary federal, state, and local authorizations
   to carry on its business as now being conducted and to carry out this
   Agreement.

       b. The Robertson Stephens Trust is registered under the Investment
   Company Act of 1940, as amended (the "1940 Act"), as an open-end management
   investment company, and such registration has not been revoked or rescinded
   and is in full force and effect.

       c. A statement of assets and liabilities, statements of operations,
   statements of changes in net assets, and a schedule of investments
   (indicating their market values) of the Acquiring Fund as of and for the
   year ended December 31, 1997 have been furnished to the Acquired Fund. Such
   statement of assets and liabilities and schedule fairly present the
   financial position of the Acquiring Fund as of their date and such
   statements of operations and changes in net assets fairly reflect the
   results of its operations and changes in net assets for the period covered
   thereby in conformity with generally accepted accounting principles.

       d. The current prospectuses and statement of additional information of
   the Robertson Stephens Trust, each dated March 1, 1998, as revised or
   supplemented to this date (collectively, the "Robertson Stephens
   Prospectus"), which have previously been furnished to the Acquired Fund,
   did not as of such date and do not contain as of the date hereof, with
   respect to the Robertson Stephens Trust and the Acquiring Fund, any untrue
   statements of a material fact or omit to state a material fact required to
   be stated therein or necessary to make the statements therein not
   misleading.

       e. There are no material legal, administrative, or other proceedings
   pending or, to the knowledge of the Robertson Stephens Trust or the
   Acquiring Fund, threatened against the Robertson Stephens Trust or the
   Acquiring Fund, which assert liability on the part of the Robertson
   Stephens Trust or the Acquiring Fund. The Acquiring Fund knows of no facts
   which might form the basis for the institution of such proceedings and is
   not a party to or subject to the provisions of any order, decree, or
   judgment of any court or governmental body which materially and adversely
   affects its business or its ability to consummate the transactions herein
   contemplated.

       f. To the best of its knowledge and except as previously disclosed to
   the Acquired Fund by the Acquiring Fund, the Acquiring Fund has no known
   liabilities of a material nature, contingent or otherwise, other than those
   shown belonging to it on its statement of assets and liabilities as of
   December 31, 1997, those incurred in the ordinary course of its business as
   an investment company since December 31, 1997 and those to be assumed
   pursuant to this Agreement. Prior to the Exchange Date, the Acquiring Fund
   will endeavor to quantify and to reflect on its balance sheet all of its
   material known liabilities and will advise the Acquired Fund of all
   material liabilities, contingent or otherwise, incurred by it subsequent to
   December 31, 1997, whether or not incurred in the ordinary course of
   business.

       g. As of the Exchange Date, the Acquiring Fund will have filed all
   federal and other tax returns and reports which, to the knowledge of the
   Robertson Stephens Trust's officers, are required to be filed by the
   Acquiring Fund and has paid or will pay all federal and other taxes shown
   to be due on said returns or on any assessments received by the Acquiring
   Fund. All tax liabilities of the Acquiring Fund have been adequately


                                      A-2

<PAGE>

   provided for on its books, and no tax deficiency or liability of the
   Acquiring Fund has been asserted, and no question with respect thereto has
   been raised or is under audit, by the Internal Revenue Service or by any
   state or local tax authority for taxes in excess of those already paid.

       h. No consent, approval, authorization, or order of any court or
   governmental authority is required for the consummation by the Acquiring
   Fund of the transactions contemplated by this Agreement, except such as may
   be required under the Securities Act of 1933, as amended (the "1933 Act"),
   the Securities Exchange Act of 1934, as amended (the "1934 Act"), the 1940
   Act, and state securities or blue sky laws (which term as used herein shall
   include the laws of the District of Columbia and of Puerto Rico).

       i. The registration statement (the "Registration Statement") filed with
   the Securities and Exchange Commission (the "Commission") by the Robertson
   Stephens Trust on Form N-14 on behalf of the Acquiring Fund and relating to
   the Merger Shares issuable hereunder and the proxy statement of the
   Acquired Fund relating to the meeting of the Acquired Fund's shareholders
   referred to in Section 7(a) herein (together with the documents
   incorporated therein by reference, the "Acquired Fund Proxy Statement"), on
   the effective date of the Registration Statement, (i) will comply in all
   material respects with the provisions of the 1933 Act, the 1934 Act, and
   the 1940 Act and the rules and regulations thereunder and (ii) will not
   contain any untrue statement of a material fact or omit to state a material
   fact required to be stated therein or necessary to make the statements
   therein not misleading; and at the time of the shareholders meeting
   referred to in Section 7(a) and on the Exchange Date, the prospectuses
   which are contained in the Registration Statement, as amended or
   supplemented by any amendments or supplements filed with the Commission by
   the Robertson Stephens Trust, and the Acquired Fund Proxy Statement will
   not contain any untrue statement of a material fact or omit to state a
   material fact required to be stated therein or necessary to make the
   statements therein not misleading; provided, however, that none of the
   representations and warranties in this subsection shall apply to statements
   in or omissions from the Registration Statement or the Acquired Fund Proxy
   Statement made in reliance upon and in conformity with information
   furnished in writing by the Acquired Fund to the Acquiring Fund or the
   Robertson Stephens Trust specifically for use in the Registration Statement
   or the Acquired Fund Proxy Statement.

       j. There are no material contracts outstanding to which the Acquiring
   Fund is a party, other than as are or will be disclosed in the Robertson
   Stephens Prospectus, the Registration Statement, or the Acquired Fund Proxy
   Statement.

       k. The Acquiring Fund qualifies and will at all times through the
   Exchange Date qualify for taxation as a "regulated investment company"
   under Sections 851 and 852 of the Internal Revenue Code of 1986, as amended
   (the "Code").

       l. The issuance of the Merger Shares pursuant to this Agreement will be
   in compliance with all applicable federal and state securities laws.

       m. The Merger Shares to be issued to the Acquired Fund have been duly
   authorized and, when issued and delivered pursuant to this Agreement, will
   be legally and validly issued and will be fully paid and non-assessable by
   the Acquiring Fund, and no shareholder of the Acquiring Fund will have any
   preemptive right of subscription or purchase in respect thereof.

       n. All issued and outstanding shares of the Acquiring Fund are, and at
   the Exchange Date will be, duly authorized, validly issued, fully paid, and
   non-assessable by the Acquiring Fund. The Acquiring Fund does


                                      A-3

<PAGE>

   not have outstanding any options, warrants, or other rights to subscribe
   for or purchase any of the Acquiring Fund shares, nor is there outstanding
   any security convertible into any Acquiring Fund shares.

     2. Representations, Warranties, and Agreements of the Acquired Fund. The
Acquired Fund represents and warrants to and agrees with the Acquiring Fund
that:

       a. The Acquired Fund is a series of shares of the Robertson Stephens
   Trust, a Massachusetts business trust duly established and validly existing
   under the laws of The Commonwealth of Massachusetts, and has power to own
   all of its properties and assets and to carry out this Agreement. The
   Robertson Stephens Trust is qualified as a foreign association in every
   jurisdiction where required, except to the extent that failure to so
   qualify would not have a material adverse effect on the Robertson Stephens
   Trust. Each of the Robertson Stephens Trust and the Acquired Fund has all
   necessary federal, state, and local authorizations to own all of its
   properties and assets and to carry on its business as now being conducted
   and to carry out this Agreement.

       b. The Robertson Stephens Trust is registered under the 1940 Act as an
   open-end management investment company, and such registration has not been
   revoked or rescinded and is in full force and effect.

       c. A statement of assets and liabilities, statement of operations,
   statement of changes in net assets, and a schedule of investments
   (indicating their market values) of the Acquired Fund as of and for the
   fiscal year ended December 31, 1997 have been furnished to the Acquiring
   Fund. Such statement of assets and liabilities and schedule fairly present
   the financial position of the Acquired Fund as of their date, and such
   statements of operations and changes in net assets fairly reflect the
   results of its operations and changes in net assets for the period covered
   thereby, in conformity with generally accepted accounting principles.

       d. The Robertson Stephens Prospectus, which has been previously
   furnished to the Acquiring Fund, did not contain as of March 1, 1998 and
   does not contain, with respect to the Robertson Stephens Trust and the
   Acquired Fund, any untrue statement of a material fact or omit to state a
   material fact required to be stated therein or necessary to make the
   statements therein not misleading.

       e. There are no material legal, administrative, or other proceedings
   pending or, to the knowledge of the Robertson Stephens Trust or the
   Acquired Fund, threatened against the Robertson Stephens Trust or the
   Acquired Fund, which assert liability on the part of the Robertson Stephens
   Trust or the Acquired Fund. The Acquired Fund knows of no facts which might
   form the basis for the institution of such proceedings and is not a party
   to or subject to the provisions of any order, decree, or judgment of any
   court or governmental body which materially and adversely affects its
   business or its ability to consummate the transactions herein contemplated.
    

       f. There are no material contracts outstanding to which the Acquired
   Fund is a party, other than as are or will be disclosed in the Robertson
   Stephens Trust's registration statement on Form N-1A or the Robertson
   Stephens Prospectus.

       g. To the best of its knowledge and except as previously disclosed to
   the Acquiring Fund by the Acquired Fund, the Acquired Fund has no known
   liabilities of a material nature, contingent or otherwise, other than those
   shown on the Acquired Fund's statement of assets and liabilities as of
   December 31, 1997 referred to above and those incurred in the ordinary
   course of its business as an investment company since such date. Prior to
   the Exchange Date, the Acquired Fund will endeavor to quantify and to
   reflect on its


                                      A-4

<PAGE>

   balance sheet all of its material known liabilities and will advise the
   Acquiring Fund of all material liabilities, contingent or otherwise,
   incurred by it subsequent to December 31, 1997, whether or not incurred in
   the ordinary course of business.

       h. As of the Exchange Date, the Acquired Fund will have filed all
   federal and other tax returns and reports which, to the knowledge of the
   Robertson Stephens Trust's officers, are required to be filed by the
   Acquired Fund and has paid or will pay all federal and other taxes shown to
   be due on said returns or on any assessments received by the Acquired Fund.
   All tax liabilities of the Acquired Fund have been adequately provided for
   on its books, and no tax deficiency or liability of the Acquired Fund has
   been asserted, and no question with respect thereto has been raised or is
   under audit, by the Internal Revenue Service or by any state or local tax
   authority for taxes in excess of those already paid.

       i. At the Exchange Date, the Robertson Stephens Trust, on behalf of the
   Acquired Fund, will have full right, power, and authority to sell, assign,
   transfer, and deliver the Investments (as defined below) and any other
   assets and liabilities of the Acquired Fund to be transferred to the
   Acquiring Fund pursuant to this Agreement. At the Exchange Date, subject
   only to the delivery of the Investments and any such other assets and
   liabilities as contemplated by this Agreement, the Acquiring Fund will
   acquire the Investments and any such other assets and liabilities subject
   to no encumbrances, liens, or security interests whatsoever and without any
   restrictions upon the transfer thereof. As used in this Agreement, the term
   "Investments" shall mean the Acquired Fund's investments shown on the
   schedule of its investments as of December 31, 1997 referred to in Section
   2(c) hereof, as supplemented with such changes in the portfolio as the
   Acquired Fund shall make, and changes resulting from stock dividends, stock
   split-ups, mergers, and similar corporate actions through the Exchange
   Date.

       j. No registration under the 1933 Act of any of the Investments would be
   required if they were, as of the time of such transfer, the subject of a
   public distribution by either of the Acquiring Fund or the Acquired Fund,
   except as previously disclosed to the Acquiring Fund by the Acquired Fund.

       k. No consent, approval, authorization, or order of any court or
   governmental authority is required for the consummation by the Acquired
   Fund of the transactions contemplated by this Agreement, except such as may
   be required under the 1933 Act, 1934 Act, the 1940 Act, or state securities
   or blue sky laws.

       l. The Registration Statement and the Acquired Fund Proxy Statement, on
   the effective date of the Registration Statement, (i) will comply in all
   material respects with the provisions of the 1933 Act, the 1934 Act, and
   the 1940 Act and the rules and regulations thereunder and (ii) will not
   contain any untrue statement of a material fact or omit to state a material
   fact required to be stated therein or necessary to make the statements
   therein not misleading; and at the time of the shareholders meeting
   referred to in Section 7(a) and on the Exchange Date, the Acquired Fund
   Proxy Statement and the Registration Statement will not contain any untrue
   statement of a material fact or omit to state a material fact required to
   be stated therein or necessary to make the statements therein not
   misleading; provided, however, that none of the representations and
   warranties in this subsection shall apply to statements in or omissions
   from the Registration Statement or the Acquired Fund Proxy Statement made
   in reliance upon and in conformity with information furnished in writing by
   the Acquiring Fund to the Acquired Fund or the Robertson Stephens Trust
   specifically for use in the Registration Statement or the Acquired Fund
   Proxy Statement.

       m. The Acquired Fund qualifies and will at all times through the
   Exchange Date qualify for taxation as a "regulated investment company"
   under Section 851 and 852 of the Code.


                                      A-5

<PAGE>

       n. All issued and outstanding shares of the Acquired Fund are, and at
   the Exchange Date will be, duly authorized, validly issued, fully paid, and
   nonassessable by the Acquired Fund. The Acquired Fund does not have
   outstanding any options, warrants, or other rights to subscribe for or
   purchase any of the Acquired Fund shares, nor is there outstanding any
   security convertible into any of the Acquired Fund shares.

   3. Reorganization.

       a. Subject to the requisite approval of the shareholders of the Acquired
   Fund and to the other terms and conditions contained herein (including the
   Acquired Fund's obligation to distribute to its shareholders all of its
   investment company taxable income and net capital gain as described in
   Section 8(k) hereof), the Acquired Fund agrees to sell, assign, convey,
   transfer, and deliver to the Acquiring Fund, and the Acquiring Fund agrees
   to acquire from the Acquired Fund, on the Exchange Date all of the
   Investments and all of the cash and other properties and assets of the
   Acquired Fund, whether accrued or contingent (including cash received by
   the Acquired Fund upon the liquidation by the Acquired Fund of any
   investments), in exchange for that number of shares of beneficial interest
   of the Acquiring Fund provided for in Section 4 and the assumption by the
   Acquiring Fund of all of the liabilities of the Acquired Fund, whether
   accrued or contingent, existing at the Valuation Time (as defined below)
   except for the Acquired Fund's liabilities, if any, arising in connection
   with this Agreement. Pursuant to this Agreement, the Acquired Fund will, as
   soon as practicable after the Exchange Date, distribute all of the Merger
   Shares received by it to the shareholders of the Acquired Fund in exchange
   for their Class A and Class C shares of the Acquired Fund.

       b. The Acquired Fund will pay or cause to be paid to the Acquiring Fund
   any interest, cash, or such dividends, rights, and other payments received
   by it on or after the Exchange Date with respect to the Investments and
   other properties and assets of the Acquired Fund, whether accrued or
   contingent, received by it on or after the Exchange Date. Any such
   distribution shall be deemed included in the assets transferred to the
   Acquiring Fund at the Exchange Date and shall not be separately valued
   unless the securities in respect of which such distribution is made shall
   have gone "ex" such distribution prior to the Valuation Time, in which case
   any such distribution which remains unpaid at the Exchange Date shall be
   included in the determination of the value of the assets of the Acquired
   Fund acquired by the Acquiring Fund.

       c. The Valuation Time shall be 4:30 p.m. Eastern time on the Exchange
   Date or such earlier or later day as may be mutually agreed upon in writing
   by the parties hereto (the "Valuation Time").

     4. Exchange Date: Valuation Time. On the Exchange Date, the Acquiring Fund
will deliver to the Acquired Fund (i) a number of full and fractional Class A
Merger Shares having an aggregate net asset value equal to the value of the
assets of the Acquired Fund attributable to Class A shares of the Acquired Fund
transferred to the Acquiring Fund on such date less the value of the
liabilities of the Acquired Fund attributable to Class A shares of the Acquired
Fund assumed by the Acquiring Fund on that date and (ii) a number of full and
fractional Class C Merger Shares having an aggregate net asset value equal to
the value of the assets of the Acquired Fund attributable to Class C shares of
the Acquired Fund transferred to the Acquiring Fund on such date less the value
of the liabilities of the Acquired Fund attributable to Class C shares of the
Acquired Fund assumed by the Acquiring Fund on that date, determined as
hereinafter provided in this Section 4.

       a. The net asset value of the Merger Shares to be delivered to the
   Acquired Fund, the value of the assets attributable to the Class A and
   Class C shares of the Acquired Fund, and the value of the liabilities
   attributable to the Class A and Class C shares of the Acquired Fund to be
   assumed by the Acquiring Fund, shall in each case be determined as of the
   Valuation Time.


                                      A-6

<PAGE>

       b. The net asset value of the Class A and Class C Merger Shares shall be
   computed in the manner set forth in the Robertson Stephens Prospectus. The
   value of the assets and liabilities of the Class A and Class C shares of
   the Acquired Fund shall be determined by the Acquiring Fund, in cooperation
   with the Acquired Fund, pursuant to procedures which the Acquiring Fund
   would use in determining the fair market value of the Acquiring Fund's
   assets and liabilities.

       c. No adjustments shall be made in the net asset value of either the
   Acquired Fund or the Acquiring Fund to take into account differences in
   realized and unrealized gains and losses.

       d. The Acquired Fund shall distribute the Class A Merger Shares to the
   Class A shareholders of the Acquired Fund by furnishing written
   instructions to the Acquiring Fund's transfer agent, which will as soon as
   practicable set up open accounts for each Class A Acquired Fund shareholder
   in accordance with such written instructions. The Acquired Fund shall
   distribute the Class C Merger Shares to the Class C shareholders of the
   Acquired Fund by furnishing written instructions to the Acquiring Fund's
   transfer agent, which will as soon as practicable set up open accounts for
   each Class C Acquired Fund shareholder in accordance with such written
   instructions.

       e. The Acquiring Fund shall assume all liabilities of the Acquired Fund,
   whether accrued or contingent, in connection with the acquisition of assets
   and subsequent dissolution of the Acquired Fund or otherwise, except for
   the Acquired Fund's liabilities, if any, pursuant to this Agreement.

   5. Expenses, Fees, Etc.

       a. All legal and accounting fees and expenses, printing, filing, and
   proxy solicitation expenses, portfolio transfer taxes (if any), brokerage,
   and similar expenses incurred in connection with the transactions
   contemplated by the Agreement will be borne by the Acquiring Fund and the
   Acquired Fund in the same proportion as their respective aggregate net
   asset values bear to each other, whether or not such transactions are
   consummated. Notwithstanding any of the foregoing, expenses will in any
   event be paid by the party directly incurring such expenses if and to the
   extent that the payment by the other party of such expenses would result in
   the disqualification of such party as a "regulated investment company"
   within the meaning of Section 851 of the Code.

       b. Notwithstanding any other provision of this Agreement, if for any
   reason the transactions contemplated by this Agreement are not consummated,
   no party shall be liable to the other party for any damages resulting
   therefrom, including, without limitation, consequential damages, except as
   specifically set forth above.

     6. Exchange Date. Delivery of the assets of the Acquired Fund to be
transferred, assumption of the liabilities of the Acquired Fund to be assumed,
and the delivery of the Merger Shares to be issued shall be made at the offices
of Ropes & Gray, One International Place, Boston, Massachusetts 02110 as of
August   , 1998, or at such other date agreed to by the Acquiring Fund and the
Acquired Fund, the date and time upon which such delivery is to take place
being referred to herein as the "Exchange Date."

   7. Meetings of Shareholders; Dissolution.

       a. The Robertson Stephens Trust, on behalf of the Acquired Fund, agrees
   to call a meeting of the Acquired Fund's shareholders as soon as is
   practicable after the effective date of the Registration Statement for the
   purpose of considering the sale of all of its assets to and the assumption
   of all of its liabilities by


                                      A-7

<PAGE>

   the Acquiring Fund as herein provided, adopting this Agreement, and
   authorizing the liquidation and dissolution of the Acquired Fund.

       b. The Acquired Fund agrees that the liquidation and dissolution of the
   Acquired Fund will be effected in the manner provided in the Robertson
   Stephens Trust's Agreement and Declaration of Trust in accordance with
   applicable law and that on and after the Exchange Date, the Acquired Fund
   shall not conduct any business except in connection with its liquidation
   and dissolution.

       c. The Acquiring Fund has, in consultation with the Acquired Fund and
   based in part on information furnished by the Acquired Fund, filed the
   Registration Statement with the Commission. The Acquired Fund and the
   Acquiring Fund will cooperate with each other and will furnish to each
   other the information relating to itself required by the 1933 Act, the 1934
   Act, and the 1940 Act and the rules and regulations thereunder to be set
   forth in the Registration Statement.

Acquiring Fund hereunder shall be subject to the following conditions:

   Trust's President (or any Vice President) and Treasurer (or any Assistant
   Treasurer), and a certificate of both such officers, dated the Exchange
   Date, that there has been no material adverse change in the financial

   of the Robertson

<PAGE>

   Stephens Trust (for purposes of this subparagraph, the "Indemnified
   Parties") against any and all expenses, losses, claims, damages, and
   liabilities at any time imposed upon or reasonably incurred by any one or
   more of the Indemnified Parties in connection with, arising out of, or
   resulting from any claim, action, suit, or proceeding in which any one or
   more of the Indemnified Parties may be involved or with which any one or
   more of the Indemnified Parties may be threatened by reason of any untrue
   statement or alleged untrue statement of a material fact relating to the
   Acquired Fund contained in the Registration Statement, the Robertson
   Stephens Prospectus, the Acquired Fund Proxy Statement, or any amendment or
   supplement to any of the foregoing, or arising out of or based upon the
   omission or alleged omission to state in any of the foregoing a material
   fact relating to the Acquired Fund required to be stated therein or
   necessary to make the statements relating to the Acquired Fund therein not
   misleading, including, without limitation, any amounts paid by any one or
   more of the Indemnified Parties in a reasonable compromise or settlement of
   any such claim, action, suit, or proceeding, or threatened claim, action,
   suit, or proceeding made with the consent of the Robertson Stephens Trust
   or the Acquired Fund. The Indemnified Parties will notify the Robertson
   Stephens Trust and the Acquired Fund in writing within ten days after the
   receipt by any one or more of the Indemnified Parties of any notice of
   legal process or any suit brought against or claim made against such
   Indemnified Party as to any matters covered by this Section 10(a). The
   Acquired Fund shall be entitled to participate at its own expense in the
   defense of any claim, action, suit, or proceeding covered by this Section
   10(a), or, if it so elects, to assume at its expense by counsel
   satisfactory to the Indemnified Parties the defense of any such claim,
   action, suit, or proceeding, and if the Acquired Fund elects to assume such
   defense, the Indemnified Parties shall be entitled to participate in the
   defense of any such claim, action, suit, or proceeding at their expense.
   The Acquired Fund's obligation under Section 10(a) to indemnify and hold
   harmless the Indemnified Parties shall constitute a guarantee of payment so
   that the Acquired Fund will pay in the first instance any expenses, losses,
   claims, damages, and liabilities required to be paid by it under this
   Section 10(a) without the necessity of the Indemnified Parties' first
   paying the same.

       b. The Acquiring Fund will indemnify and hold harmless, out of the
   assets of the Acquiring Fund but no other assets, the Acquired Fund and the
   trustees and officers of the Robertson Stephens Trust (for purposes of this
   subparagraph, the "Indemnified Parties") against any and all expenses,
   losses, claims, damages, and liabilities at any time imposed upon or
   reasonably incurred by any one or more of the Indemnified Parties in
   connection with, arising out of, or resulting from any claim, action, suit,
   or proceeding in which any one or more of the Indemnified Parties may be
   involved or with which any one or more of the Indemnified Parties may be
   threatened by reason of any untrue statement or alleged untrue statement of
   a material fact relating to the Acquiring Fund contained in the
   Registration Statement, the Robertson Stephens Prospectus, the Acquired
   Fund Proxy Statement, or any amendment or supplement to any of the
   foregoing, or arising out of or based upon, the omission or alleged
   omission to state in any of the foregoing a material fact relating to the
   Acquiring Fund required to be stated therein or necessary to make the
   statements relating to the Acquiring Fund therein not misleading,
   including, without limitation, any amounts paid by any one or more of the
   Indemnified Parties in a reasonable compromise or settlement of any such
   claim, action, suit, or proceeding, or threatened claim, action, suit, or
   proceeding, made with the consent of the Robertson Stephens Trust or the
   Acquiring Fund. The Indemnified Parties will notify the Robertson Stephens
   Trust and the Acquiring Fund in writing within ten days after the receipt
   by any one or more of the Indemnified Parties of any notice of legal
   process or any suit brought against or claim made against such Indemnified
   Party as to any matters covered by this Section 10(b). The Acquiring Fund
   shall be entitled to participate at its own expense in the defense of any
   claim, action, suit, or proceeding covered by this Section


                                      A-12

<PAGE>

   10(b), or, if it so elects, to assume at its expense by counsel
   satisfactory to the Indemnified Parties the defense of any such claim,
   action, suit, or proceeding, and, if the Acquiring Fund elects to assume
   such defense, the Indemnified Parties shall be entitled to participate in
   the defense of any such claim, action, suit, or proceeding at their own
   expense. The Acquiring Fund's obligation under this Section 10(b) to
   indemnify and hold harmless the Indemnified Parties shall constitute a
   guarantee of payment so that the Acquiring Fund will pay in the first
   instance any expenses, losses, claims, damages, and liabilities required to
   be paid by it under this Section 10(b) without the necessity of the
   Indemnified Parties' first paying the same.

     11. No Broker, Etc. Each of the Acquired Fund and the Acquiring Fund
represents that there is no person who has dealt with it or the Robertson
Stephens Trust who by reason of such dealings is entitled to any broker's or
finder's or other similar fee or commission arising out of the transactions
contemplated by this Agreement.

   
     12. Termination. The Acquired Fund and the Acquiring Fund may, by mutual
consent of the trustees of the Robertson Stephens Trust on behalf of each fund,
terminate this Agreement, and the Acquired Fund or the Acquiring Fund, after
consultation with counsel and by consent of their respective trustees or an
officer authorized by such trustees, may waive any condition to their
respective obligations hereunder. If the transactions contemplated by this
Agreement have not been substantially completed by October 31, 1998, this
Agreement shall automatically terminate on that date unless a later date is
agreed to by the Acquired Fund and the Acquiring Fund.
    

     13. Rule 145. Pursuant to Rule 145 under the 1933 Act, the Acquiring Fund
will, in connection with the issuance of any Merger Shares to any person who at
the time of the transaction contemplated hereby is deemed to be an affiliate of
a party to the transaction pursuant to Rule 145(c), cause to be affixed upon
the certificates issued to such person (if any) a legend as follows:

       "THESE SHARES MAY NOT BE SOLD OR OTHERWISE TRANSFERRED EXCEPT TO THE
   PARTNERS FUND OR ITS PRINCIPAL UNDERWRITER UNLESS (I) A REGISTRATION
   STATEMENT WITH RESPECT THERETO IS EFFECTIVE UNDER THE SECURITIES ACT OF
   1933, AS AMENDED, OR (II) IN THE OPINION OF COUNSEL REASONABLY SATISFACTORY
   TO THE FUND SUCH REGISTRATION IS NOT REQUIRED."

and, further, the Acquiring Fund will issue stop transfer instructions to the
Acquiring Fund's transfer agent with respect to such shares. The Acquired Fund
will provide the Acquiring Fund on the Exchange Date with the name of any
Acquired Fund shareholder who is to the knowledge of the Acquired Fund an
affiliate of the Acquired Fund on such date.

     14. Covenants, Etc. Deemed Material. All covenants, agreements,
representations, and warranties made under this Agreement and any certificates
delivered pursuant to this Agreement shall be deemed to have been material and
relied upon by each of the parties, notwithstanding an investigation made by
them or on their behalf.

     15. Sole Agreement; Amendments; Governing Law. This Agreement supersedes
all previous correspondence and oral communications between the parties
regarding the subject matter hereof, constitutes the only understanding with
respect to such subject matter, may not be changed except by a letter of
agreement signed by each party hereto, and shall be construed in accordance
with and governed by the laws of The Commonwealth of Massachusetts.

     16. Declaration of Trust. A copy of the Agreement and Declaration of Trust
of the Robertson Stephens Trust is on file with the Secretary of State of The
Commonwealth of Massachusetts, and notice is hereby given

assets and property of the Acquired Fund and the Acquiring Fund, as the case
may be.

     This Statement of Additional Information (the "SAI") relates to the
proposed merger (the "Merger") of the Robertson Stephens  Developing
Countries Fund (the "Acquired Fund"), a series of Robertson Stephens Investment
Trust, a Massachusetts business trust (the "Trust"), into the Robertson Stephens

     This SAI contains information which may be of interest to shareholders but
which is not included in the Prospectus/Proxy Statement dated August __, 1998

liabilities of the Acquired Fund. The Acquired Fund would distribute the
Acquiring Fund shares it receives to its shareholders in complete liquidation of
the Acquired Fund.
    

     This SAI is not a prospectus and should be read in conjunction with the
Prospectus/Proxy Statement. The Prospectus/Proxy Statement has been filed with
the Securities and Exchange Commission and is available upon request and without
charge by writing to the Trust at 555 California Street, San Francisco,
California 94104 or by calling 1-800-766-3863.

                                  OTHER INFORMATION

ITEM 15.  INDEMNIFICATION.

     Under the terms of Registrant's By-laws, Article VI, Registrant is
required, subject to certain exceptions and limitations, to indemnify and insure
its trustees, officers, employees, agents and other persons who may be
indemnified by Registrant under the Investment Company Act of 1940 (the "1940
Act").

     Insofar as indemnification for liabilities arising under the Securities Act
is permitted to trustees and officers and controlling persons of Registrant
pursuant to the foregoing provisions, or otherwise, Registrant has been advised
that, in the opinion of the Securities and Exchange Commission, such
indemnification by Registrant is against public policy as expressed in the
Securities Act, and therefore may be unenforceable. In the event that a claim
for such indemnification (except insofar as it provides for the payment by
Registrant of expenses incurred or paid by a trustee, officer or controlling
person in the successful defense of any action, suit or proceeding) is asserted
against Registrant by any trustee, officer or controlling person and the
Securities and Exchange Commission is still of the same opinion, Registrant
will, unless in the opinion of its counsel the matter has been settled by a
controlling precedent, submit to a court of appropriate jurisdiction the
question of whether such indemnification by it is against public policy as
expressed in the Securities Act, and will be governed by the final adjudication
of such issue.

     The Trust, at its expense, provides liability insurance for the benefit of
its Trustees and officers.

          deemed to be an underwriter within the meaning of Rule 145(c) under
          the Securities Act of 1933, the reoffering prospectus will contain the
          information called for by the applicable registration form for the

Robertson Stephens Investment Trust
555 California Street
San Francisco, California  94104

Ladies and Gentlemen:

     We are furnishing this opinion in connection with the Registration
Statement on Form N-14 (the "Registration Statement") of Robertson Stephens
Investment Trust (the "Trust") relating to the registration of an indefinite
number of shares of beneficial interest of the Robertson Stephens Partners Fund
(the "Fund"), a series of shares of beneficial interest of the Trust
(collectively, the "Shares").

     In connection with this opinion, we have examined such records, documents,
and certificates of public officials and the Trust as we have deemed necessary
for the purpose of giving this opinion. We have assumed the genuineness of all
items submitted to us as originals and the conformity with originals of all
items submitted to us as copies.

     We were not involved in the organization of the Trust, and understand that
in connection with the filing of the original registration statement of the
Trust under the Securities Act of 1933, as amended, you received an opinion of
other Massachusetts counsel to the effect that the Trust is an entity of the
type commonly known as a "Massachusetts business trust". We have not examined
independently the question of what law would govern the interpretation or
enforcement of any provision of the Agreement and Declaration of Trust and have
for this purpose assumed that the Trust is a duly established and validly
existing unincorporated voluntary association with transferable shares under
Massachusetts law (commonly known as a "Massachusetts business trust") and that
the interpretation and enforcement of each provision of the Agreement and
Declaration of Trust will be governed by the laws of The Commonwealth of
Massachusetts.

     We have made such examination of Massachusetts law as we have deemed
relevant for purposes of this opinion. We express no opinion as to the effect of
laws, rules, and regulations of any state or jurisdiction other than The
Commonwealth of Massachusetts. We understand that the Shares are to be issued in
accordance with the terms of an Agreement and Plan of Reorganization (the
"Agreement") between the Trust on behalf of the Fund and the Trust on behalf of
the Robertson Stephens Developing Countries Fund, another series of shares of
the Trust. We assume that the Board of Trustees of the Trust will have duly
adopted and approved the Agreement, in the form or in substantially the form
filed as part of the Registration Statement, in respect of each such Fund prior
to the time of the issuance of the Shares.

     Based upon and subject to the foregoing, we are of the opinion that the
Shares, upon delivery thereof and payment therefor in accordance with the
Registration Statement, will be duly authorized, validly issued, fully paid, and
nonassessable by the Trust.

     Under Massachusetts law, shareholders of a Massachusetts business trust
could, under certain circumstances, be held personally liable for the
obligations of the trust.  However, the Agreement and Declaration


<PAGE>

Roberston Stephens Investment Trust                                July 2, 1998

of Trust disclaims liability of any shareholder for payment under any credit,
contract, or claim against the Trust or any series of the Trust. The Agreement
and Declaration of Trust provides for indemnification by the Trust of any
shareholder or former shareholder held liable solely by reason of his or her
being or having been a shareholder and not because of his or her acts or
omissions or for some other reason. Thus, the risk of a shareholder's incurring
financial loss on account of shareholder liability is limited to circumstances
in which the Trust itself would be unable to meet its obligations.

     This opinion is intended only for your use in connection with the offering
of Shares and may not be relied upon by any other person.

     We hereby consent to the inclusion of this opinion as an exhibit to the
Trust's Registration Statement to be filed with the Securities and Exchange
Commission.

                              Very truly yours,

                              /s/  ROPES & GRAY
                              -----------------

                               [FORM OF OPINION]


                               ___________, 1998



Robertson Stephens Developing Countries Fund
Robertson Stephens Partners Fund
Robertson Stephens Investment Trust
555 California Street
San Francisco, CA 94104

Ladies and Gentlemen:

         We have acted as counsel in connection with the Agreement and Plan of
Reorganization (the "Agreement") dated as of _________, 1998, between the
Robertson Stephens Partners Fund ("Acquiring Fund"), a series of Robertson
Stephens Investment Trust (the "Trust"), a Massachusetts business trust, and the
Robertson Stephens Developing Countries Fund ("Target Fund"), another series of
the Trust.  The Agreement describes a proposed transaction (the "Transaction")
to occur on __________, 1998 (the "Exchange Date"), pursuant to which Acquiring
Fund will acquire substantially all of the assets of Target Fund in exchange for
shares of beneficial interest in Acquiring Fund (the "Acquiring Fund Shares")
and the assumption by Acquiring Fund of all of the liabilities of Target Fund
following which the Acquiring Fund Shares received by Target Fund will be
distributed by Target Fund to its shareholders in liquidation and termination of
Target Fund.  Capitalized terms not defined herein are used herein as defined in
the Agreement.

         Target Fund is registered under the Investment Company Act of 1940, as
amended (the "1940 Act"), as an open-end non-diversified management investment
company.  Shares of Target Fund are redeemable at net asset value at each
shareholder's option.  Target Fund has elected to be a regulated investment
company for federal income tax purposes under Section 851 of the Internal
Revenue Code of 1986, as amended (the "Code").

         Acquiring Fund is registered under the 1940 Act as an open-end
non-diversified management investment company.  Shares of Acquiring Fund are
redeemable at net asset value at each shareholder's option.  Acquiring Fund has
elected to be a regulated investment company for federal income tax purposes
under Section 851 of the Code.



         For purposes of this opinion, we have considered the Agreement, the
Proxy Statement, the Registration Statement (including the items incorporated by
reference therein), and such other items as we have deemed necessary to render
this opinion.  In addition, you have represented to us the following facts,
occurrences and information upon which you have indicated we may rely in
rendering this opinion (whether or not contained or reflected in the documents
and items referred to above):


<PAGE>



Robertson Stephens Developing Countries Fund
Robertson Stephens Partners Fund    -2-                       ___________, 1998


         1.   Target Fund will transfer to Acquiring Fund all of its assets, and
Acquiring Fund will assume all of the liabilities of Target Fund, as of the
Exchange Date.

         2.   The fair market value of the Acquiring Fund Shares received by
each Target Fund shareholder will be approximately equal to the fair market
value of the Target Fund shares surrendered in exchange therefor.  Target Fund
shareholders will receive no consideration other than Acquiring Fund Shares
(which may include fractional shares) in exchange for their shares of beneficial
interest in Target Fund (the "Target Fund Shares").

         3.   None of the compensation received by any shareholder-employees of
Target Fund, if any, will be separate consideration for, or allocable to, any of
their Target Fund Shares; none of the Acquiring Fund Shares received by any
Target Fund shareholder-employees will be separate consideration for, or
allocable to, any employment; and the compensation paid to any Acquiring Fund or
Target Fund shareholder-employees, if any, will be for services actually
rendered and will be commensurate with amounts paid to third parties bargaining
at arm's length for similar services.

         4.   There is no plan or intention by any Target Fund shareholder who
owns 5% or more of the total outstanding Target Fund Shares, and to the best of
the knowledge of the management of Target Fund, there is no plan or intention on
the part of the remaining Target Fund shareholders to sell, exchange, or
otherwise dispose of a number of Acquiring Fund Shares received in the
Transaction that would reduce Target Fund shareholders' ownership of Acquiring
Fund Shares to a number of Acquiring Fund Shares having a value, as of the date
of the Transaction, of less than 50 percent of the value of all of the formerly
outstanding Target Fund Shares as of the same date.  For purposes of this
representation, Acquiring Fund Shares or Target Fund Shares surrendered by
Target Fund shareholders in redemption or otherwise disposed of, where such
dispositions, if any, appear to be initiated by Target Fund shareholders in
connection with or as a result of the Agreement or the Transaction, will be
treated as outstanding Target Fund Shares on the date of the Transaction.

         5.   Acquiring Fund has no plan or intention to reacquire any of the
Acquiring Fund Shares issued in the Transaction, except for Acquiring Fund
Shares reacquired in the ordinary course of its business as an open-end
investment company.

         6.   Acquiring Fund will acquire at least 90 percent of the fair market
value of the net assets and at least 70 percent of the fair market value of the
gross assets held by Target Fund immediately prior to the Transaction.  For
purposes of this representation, (a) amounts paid by Target Fund, out of the
assets of Target Fund, to Target Fund shareholders in redemption of Target Fund
Shares, where such redemptions, if any, appear to be initiated by Target Fund
shareholders in connection with or as a result of the Agreement or the
Transaction, (b) amounts used by Target Fund to pay expenses of the Transaction,
and (c) amounts used to effect all redemptions and distributions (except for
regular, normal dividends declared and paid in order to ensure Target Fund's
continued qualification as a regulated investment company and to avoid
fund-level income tax and excise tax (including for this purpose any dividends
referred to in representation 12 herein)) made by Target Fund immediately
preceding the transfer will be included as assets of Target Fund held
immediately prior to the Transaction.  Further, to the best of the knowledge of
the managements of each of Acquiring Fund and Target Fund, this representation
will remain true even if the amounts, if any, that Acquiring Fund pays after the
Transaction to Acquiring Fund shareholders who are former Target Fund
shareholders in redemption of Acquiring Fund Shares received in exchange for
Target Fund Shares, where such redemptions, if any, appear to be initiated by
such shareholders in connection with or as a result of the Agreement or the
Transaction, are considered to be assets of Target Fund that were not
transferred to Acquiring Fund.

Robertson Stephens Developing Countries Fund
Robertson Stephens Partners Fund    -3-                          ________, 1998


         7.   The fair market value of the assets transferred to Acquiring Fund
by Target Fund will equal or exceed the sum of the liabilities to be assumed by
Acquiring Fund.

         8.   Following the Transaction, Acquiring Fund will continue the
historic business of Target Fund as an open-end investment company that seeks
long-term growth by investing in, among other things, foreign common stocks,
preferred stocks, warrants and debt securities.

         9.   The liabilities of Target Fund to be assumed by Acquiring Fund
were incurred by Target Fund in the ordinary course of its business and are
associated with the assets transferred to Acquiring Fund.  For purposes of this
paragraph, expenses of the Transaction are not treated as liabilities.

         10.   The Transaction will offer shareholders of Target Fund an
opportunity to pursue an investment program with a similar investment objective
and investment policies that are similar in many respects, in a larger fund with
potentially reduced operating expenses.

         11.   The costs, including all fees and expenses, incurred directly in
connection with the Transaction will be borne by Acquiring Fund and Target Fund
in the same proportions as their respective net asset values bear to each other.
The Target Fund and the Acquiring Fund agree to pay the expenses preliminarily
allocated to them.  All such fees and expenses incurred by either of Acquiring
Fund and Target Fund shall be solely and directly related to the Transaction and
shall be paid directly by Acquiring Fund or Target Fund, as the case may be, to
the relevant providers of services or other payees, in accordance with the
principles set forth in Rev. Rul. 73-54, 1973-1 C.B. 187.


<PAGE>



Robertson Stephens Developing Countries Fund
Robertson Stephens Partners Fund    -4-                          ________, 1998



         Target Fund shareholders will pay their respective expenses, if any,
incurred in connection with the Transaction.

         12.   For federal income tax purposes, Target Fund qualifies as a
regulated investment company, and the provisions of Sections 851 through 855 of
the Code apply to Target Fund for its current taxable year beginning January 1,
1998 and will continue to apply to it through the Exchange Date.

         In that regard, Target Fund will declare to Target Fund shareholders of
record on or prior to the Exchange Date a dividend or dividends which together
with all such previous dividends shall have the effect of distributing (a) all
of the excess of (i) Target Fund's investment income excludable from gross
income under Section 103(a) of the Code over (ii) Target Fund's deductions
disallowed under Sections 265 and 171(a)(2) of the Code, (b) all of Target
Fund's investment company taxable income (see Code Section 852) (computed in
each case without regard to any deduction for dividends paid) and (c) all of
Target Fund's net realized capital gain (after reduction for any capital loss
carryover) in each case for both the taxable year ending December 31, 1997 and
the short taxable year beginning on January 1, 1998 and ending on the Exchange
Date.  Such dividends will be made to ensure continued qualification of Target
Fund as a regulated investment company for tax purposes and to eliminate
fund-level tax.

         13.   For federal income tax purposes, Acquiring Fund qualifies as a
regulated investment company, and the provisions of Sections 851 through 855 of
the Code apply to Acquiring Fund for its current taxable year beginning January
1, 1998 and will continue to apply to it through the Exchange Date.

         14.   Acquiring Fund does not own, directly or indirectly, nor has it
owned during the past five years, directly or indirectly, any Target Fund
Shares.

         15. There is no intercorporate indebtedness existing between Target
Fund and Acquiring Fund.

         16. Target Fund will distribute the Acquiring Fund Shares it receives
in the Transaction to its shareholders as provided in the Agreement.

         17. Target Fund is not under the jurisdiction of a court in a Title 11
or similar case within the meaning of Section 368(a)(3)(A) of the Code.

         Based on the foregoing representations and our review of the documents
and items referred to above, we are of the opinion that for federal income tax
purposes it is more likely than not that:


<PAGE>


Robertson Stephens Developing Countries Fund
Robertson Stephens Partners Fund    -5-                          ________, 1998


     (i) No gain or loss will be recognized by Acquiring Fund upon the receipt
         of the assets of Target Fund in exchange for Acquiring Fund Shares and
         the assumption by Acquiring Fund of the liabilities of Target Fund;

    (ii) The basis in the hands of Acquiring Fund of the assets of Target Fund
         transferred to Acquiring Fund in the Transaction will be the same as
         the basis of such assets in the hands of Target Fund immediately prior
         to the transfer;

   (iii) The holding periods of the assets of Target Fund in the hands of
         Acquiring Fund will include the periods during which such assets were
         held by Target Fund;

    (iv) No gain or loss will be recognized by Target Fund upon the transfer of
         Target Fund's assets to Acquiring Fund in exchange for Acquiring Fund
         Shares and the assumption by Acquiring Fund of the liabilities of
         Target Fund, or upon the distribution of Acquiring Fund Shares by
         Target Fund to its shareholders in liquidation;

     (v) No gain or loss will be recognized by Target Fund shareholders upon the
         exchange of their Target Fund Shares for Acquiring Fund Shares;

    (vi) The basis of Acquiring Fund Shares a Target Fund shareholder receives
         in connection with the Transaction will be the same as the basis of his
         or her Target Fund Shares exchanged therefor; and

   (vii) A Target Fund shareholder's holding period for his or her Acquiring
         Fund Shares will be determined by including the period for which he or
         she held the Target Fund Shares exchanged therefor, provided that he or
