A SPECTRUM OF INVESTMENT
ALTERNATIVES
 
The Winthrop Family of Mutual Funds ('Winthrop') gives investors the opportunity
to invest in pools of managed assets, or 'Funds,' with differing investment
objectives as stated below:
 
WINTHROP FOCUS FUNDS
 
GROWTH FUND
Seeks . . . Long-term growth of capital by investing principally in equity
securities with long-term capital appreciation potential.
 
GROWTH AND INCOME FUND
Seeks . . . Long-term growth of capital and continuity of income by investing
principally in dividend-paying common stocks and other equity securities.
 
SMALL COMPANY VALUE FUND
Seeks . . . A high level of growth of capital by investing principally in equity
securities selected on the basis, in the investment adviser's opinion, of their
potential for a high level of growth of capital.
 
FIXED INCOME FUND
Seeks . . . To provide as high a level of total return as is consistent with
capital preservation by investing principally in debt securities.
 
MUNICIPAL TRUST FUND
Seeks . . . To provide as high a level of total return as is consistent with
capital preservation by investing principally in municipal securities. This
investment objective, unlike most other municipal bond funds, is not to provide
current income which is exempt from U.S. federal and/or state income tax. Please
read carefully 'Investment Objectives and Policies-- Municipal Trust Fund.'
 
WINTHROP INTERNATIONAL FUNDS
 
DEVELOPING MARKETS FUND
Seeks . . . Long-term growth of capital by investing primarily in common stocks
and other equity securities from developing countries.
 
INTERNATIONAL EQUITY FUND
Seeks . . . Long-term growth of capital by investing primarily in common stocks
and other equity securities from established markets outside the United States.
 
WINTHROP MONEY FUNDS
 
MUNICIPAL MONEY FUND
Seeks . . . Maximum current income, consistent with liquidity and safety of
principal, that is exempt from Federal income taxes by investing principally in
a diversified portfolio of municipal securities.

U.S. GOVERNMENT MONEY FUND
Seeks . . . Maximum current income, consistent with liquidity and safety of

principal, by investing in a portfolio of U.S. Government securities.
 
Each Winthrop Fund is a diversified, open-end investment management company
commonly known as a 'mutual fund.' The Focus Funds are portfolios of the
Winthrop Focus Funds. The International Funds and the Money Funds are portfolios
of the Winthrop Opportunity Funds (the 'Opportunity Funds'). Because the Focus
Funds and the Opportunity Funds each offer multiple Funds, they are known as
'series funds.' They are empowered to establish additional Funds with different
investment objectives and policies and offer additional classes of shares.
 
There can, of course, be no assurance that any Winthrop Fund will achieve its
investment objective. See 'Investment Objectives and Policies' for a more
detailed description of the investment objectives and policies of each of the
Winthrop Funds.
 
PURCHASE INFORMATION
 
Shares of Winthrop Funds may be purchased directly by using the Share Purchase
Application found in this Prospectus, or through Winthrop's Distributor,
Donaldson, Lufkin & Jenrette Securities Corporation, or by contacting your
securities dealer.
 
The minimum initial investment in each Fund is $250 and the minimum for
subsequent investments is $25. These minimums are waived for investments by
certain types of accounts. Further information can be obtained from Winthrop at
the address and telephone number shown on the back cover of this Prospectus. See
'Purchases, Redemptions and Shareholder Services.'

the net asset value of the Fund (i) plus, in the case of Class A shares, an
initial sales charge imposed at the time of purchase or (ii) in the case of

Shareholder Services.'

value of each Money Fund, which is expected to be $1.00 per share. See 'Net

         +  Shares purchased directly into a Money Fund will not be subject
            to Winthrop's CDSC and therefore the expenses paid by a Money
            Fund shareholder will remain unaffected by redemption.

        ++  Ten year figures assume conversion of Class B Shares to Class A
            shares at the end of the eighth year following the date of
            purchase.
       (a)  Long-term Class B shareholders may, over time, pay more in 12b-1
            Fees than the economic equivalent of the maximum front-end sales
            charges permitted by the National Association of Securities
            Dealers, Inc. A portion of the 12b-1 Fees represents an

       (b)  Total Fund Operating Expenses have been adjusted to reflect the
            most recent reimbursement policy in effect. Referenced below is
            the amount of management fees voluntarily waived or expenses
            assumed by each Fund's adviser or its affiliates or, in the case
            of the International Equity Fund and the Developing Markets Fund,
            the Funds' adviser and subadviser. In addition, the table below
            shows what Other Expenses and Total Fund Operating Expenses would
            have been without such reimbursement during the past fiscal year
            or, in the case of the Municipal Money Fund and U.S. Government
            Money Fund, during the period from the Funds' inception on
            February 24, 1997 through October 31, 1997.

            For the Funds referenced, the Funds' investment adviser or its
            affiliates or, in the case of the Developing Markets Fund and the
            International Equity Fund, the Funds' investment adviser and
            investment subadviser have agreed to the current reimbursement
            policy through April 30, 1998. After April 30, this practice may
            be discontinued with respect to any of the above Winthrop Funds.
       (c)  The expense ratios for each class of shares of the Developing
            Markets Fund and the International Equity Fund are higher than
            those paid by most other investment companies, but Wood,

            Struthers & Winthrop Management Corp. (as adviser) and AXA Asset
            Management Partenaires (as subadviser) believe the fees are
            comparable to those paid by investment companies of similar
            investment orientation.
       (d)  Annualized
       (e)  The maximum allowable amount payable for distributing shares is
            .40 of 1% of the average daily net assets of each Money Fund. The
            Board of Trustees has currently limited the amount payable to .25
            of 1% of the average daily net assets of each Money Fund.
</TABLE>
    
 
For each Fund and share class, the Examples show the cumulative expenses a
shareholder would pay on a hypothetical $1,000 investment over various periods
assuming that the investment appreciated at a 5% annual rate of return. The
Examples should not be considered a representation of past or future expenses
and actual expenses may be greater or less than those shown. Winthrop has
entered into a Distribution Agreement and 12b-1 Plan for each class of each Fund
pursuant to which a 12b-1 fee is paid to Winthrop's distributor each month. The
12b-1 fee for each class is comprised of a service fee not exceeding .25% of the
average daily net assets of the Fund attributable to the class and an
asset-based sales charge equal to the remaining portion of the 12b-1 fee. See
'Expenses of Winthrop--Distribution Agreement.'

                                  INTRODUCTION
        ---------------------------------------------------------------
 
Each of Winthrop's Funds is a separate pool of assets constituting, in effect, a
separate Fund with its own investment objective and policies. (See 'Investment
Objectives and Policies.') A shareholder may utilize Winthrop's exchange
privilege to transfer assets to the same class of shares in another Winthrop
Fund or to shares of the Money Funds in accordance with his or her changing
perception of the relative investment potential of each investment alternative.
(See 'Purchases, Redemptions and Shareholder Services-- Additional Shareholder
Services.') Shareholders of all classes of a Fund are entitled to their pro rata
share of any dividends and distributions arising from that Fund's assets except
that with respect to each Fund, each class of shares bears different
distribution expenses. (See 'Dividends, Distributions and Taxes.') Upon
redeeming shares of a Fund, the shareholder will receive the next-determined net
asset value of that Fund represented by the redeemed shares less the applicable
contingent deferred sales charge, if any. (See 'Purchases, Redemptions and
Shareholder Services.')
 
A shareholder will pay a higher 12b-1 Fee after exchanging Class A shares of the
International Funds (.25 of 1% annually) for Class A shares of the Focus Funds
(.30 of 1% annually) or after exchanging shares of the Money Funds (.25 of 1%
annually) for Class A shares of the Focus Funds or for Class B shares of either
the Focus Funds or the International Funds (1% annually). (See 'Purchases,
Redemptions and Shareholder Services.')
 
Wood Struthers & Winthrop Management Corp. ('WSWMC') acts as the investment
adviser to the Focus Funds and the International Funds. DLJ Investment
Management Corp. ('DLJIM') acts as the investment adviser to the Money Funds.
WSWMC and DLJIM (each, an 'Adviser' and together, the 'Advisers') are
subsidiaries of Donaldson, Lufkin & Jenrette Securities Corporation, the Funds'
distributor. (See 'Management' for a more detailed discussion of the Funds'
investment advisers and investment advisory services).
 

This Prospectus sets forth information about all the Funds. The Opportunity
Funds and the Focus Funds are different legal entities and are separately
offering their securities hereby. Based on the advice of counsel, the Funds
believe that the potential liability of each Fund with respect to the disclosure
in this Prospectus extends only to the disclosure relating to that Fund.
 
INVESTMENT OBJECTIVES AND POLICIES
 
   
The investment objectives of each Fund are fundamental policies of that Fund and
may not be changed without the approval of that Fund's shareholders. Except as
set forth in the Funds' Statements of Additional Information, or as otherwise
indicated below, the investment policies and restrictions of each Fund are not
fundamental policies and may be changed by the Board of Trustees (the
'Trustees') of such Fund without a shareholder vote. A more detailed explanation
of the Funds' policies and the securities and instruments they may buy or use is
contained in each Fund's Statement of Additional Information, which is available
upon request.
    
 
The investment objectives and policies of each Fund are set forth below. There
can be, of course, no assurance that any of the Funds will achieve its
respective investment objective.

        ---------------------------------------------------------------
                                THE FOCUS FUNDS
        ---------------------------------------------------------------
 
   
WINTHROP GROWTH FUND
    
 
The investment objective of the Winthrop Growth Fund (the 'Growth Fund') is
long-term capital appreciation. Investments will be made based upon their
potential for long-term capital appreciation. However, the Growth Fund may make
an investment to earn income when, in the opinion of the Adviser, such an
investment will not compromise the Growth Fund's investment objective.
 
It is the policy of the Growth Fund to invest principally in common stock,
securities convertible into common stock and other equity securities (i.e.,
preferred stock, interests in master limited partnerships) of well-known and
established companies (generally, companies in operation for more than three
years) as well as new and unseasoned companies which, in the opinion of the
Adviser, have the potential for long-term capital appreciation. Investments in
new and unseasoned companies which have limited operating histories may involve
risks not present in investments in established and well-known companies.
 
Under normal circumstances, the Growth Fund will have at least 65% of the value
of its total assets invested in equity securities of companies which in the
opinion of the Adviser have long-term capital appreciation potential. The
selection of securities on the basis of their appreciation possibilities
provides an opportunity for greater capital gain which may involve a
corresponding greater risk of capital loss than would the selection of a more
conservative equity portfolio. However, the Growth Fund reserves the right, when

the Adviser determines it is appropriate, to invest in investment grade
short-term fixed income securities and other investment grade debt securities,
enter into repurchase agreements and hold cash for temporary defensive purposes
without regard for the above limitation. In addition, under normal circumstances
the Growth Fund may invest up to 35% of the value of its total assets in equity
securities selected on a basis other than long-term capital appreciation
potential, investment grade fixed income securities, including bonds,
debentures, notes, asset and mortgage-backed securities and money market
instruments such as commercial paper and bankers acceptances and other financial
instruments. The Growth Fund may invest only in debt securities that are of
investment grade quality at the
 
                                       10

<PAGE>

time of purchase. (See 'Additional General Investment Policies--Mortgage and
Asset-Backed Securities' and 'Investment Grade Debt Securities.')
 
It is the policy of the Growth Fund to invest in companies or industries
believed to offer the opportunity for long-term capital appreciation.
 
The Adviser applies extensive research on the growth prospects of stocks the
Growth Fund is considering buying. Target companies normally have a market
capitalization of at least $1 billion at the time of purchase, and the Adviser
seeks to identify companies with growth rates that it expects will exceed that
of the S&P 500 index. In addition, with the exception of the electric and the
gas utilities sectors, the Fund is 'sector neutral,' which means that the
Adviser allocates its assets among industries in proportion to the sector
allocation of the S&P 500 index. Other factors considered in the selection of
securities include the economic and political outlook, the value of a particular
security relative to another security, trends in the determinants of corporate
profits, and management capability and practices.
 
The Growth Fund may invest in both listed and unlisted securities. Unlisted
securities may be less liquid and more volatile than listed securities. The
Growth Fund may also (i) invest up to 10% of the value of its total assets in
foreign securities, (ii) invest no more than 10% of its net assets (determined
at the time of purchase) in restricted securities or other instruments having no
ready market, (iii) invest up to 5% of its total assets in warrants, and (iv) to
minimize the effect of a market decline on the value of its securities, write
covered call options on securities or stock indices.
 
For additional information on the use, risks and costs of the above referenced
policies and practices, see 'Additional General Investment Policies.'
 
   
WINTHROP GROWTH AND INCOME FUND
    
 
The investment objective of the Winthrop Growth and Income Fund (the 'Growth and
Income Fund') is long-term capital appreciation and continuity of income. The
Growth and Income Fund pursues its investment objective by investing principally
in dividend-paying common stock and diversifying its investments among different

industries and different companies. Accordingly, the Growth and Income Fund
invests in securities on the basis of the Adviser's evaluation of their
investment merit and their potential for appreciation in value and/or income.
The selection of securities on the basis of their capital appreciation or income
potential cannot ensure against possible loss in value.
 
The Growth and Income Fund may invest in common stock, securities convertible
into common stock, preferred stock, debt securities that are of investment grade
quality at the time of purchase (including bonds, debentures, notes and asset
and mortgage-backed securities), marketable obligations of, or guaranteed by,
the U.S. Government, its agencies or instrumentalities ('U.S. Government
Securities'), municipal securities (including general and special obligation
securities and industrial revenue bonds) and money market instruments, such as
commercial paper, bankers acceptances and other financial instruments. (See
'Additional General Investment Policies--Mortgage and Asset-Backed Securities'
and 'Investment Grade Debt Securities.') Although the Growth and Income Fund
emphasizes investment in common stock, there is no fixed proportion of the
Growth and Income Fund's assets that must be invested in particular types of
securities. The proportion of assets to be invested in various types of
securities will be determined from time to time by the Adviser.
 
The Growth and Income Fund may invest in both listed and unlisted securities.
Unlisted securities may be less liquid and more volatile than listed securities.
The Growth and Income Fund may also (i) invest up to 10% of the value of its
total assets in foreign securities, (ii) invest no more than 10% of its net
assets (determined at the time of purchase) in restricted securities or other
instruments having no ready market, and (iii) to minimize the effect of a market
decline in the value of its securities, write covered call options on securities
or stock indices.
 
For additional information on the use, risks and costs of the above referenced
policies and practices, see 'Additional General Investment Policies.'
 
   
WINTHROP SMALL COMPANY VALUE FUND
    
 
The investment objective of the Winthrop Small Company Value Fund (the 'Small
Company Value Fund') is a high level of growth of capital. The Small Company
Value Fund is not intended for investors whose principal objective is assured
income or preservation of capital.
 
It is the policy of the Small Company Value Fund to invest principally in common
stock and securities convertible into common stock, but it may, when deemed
appropriate by the Adviser, invest part of its assets in preferred stock, other
equity securities, bonds or other debt securities as described below. Under
normal market conditions, at least 65% of the Small Company Value Fund's total
assets will be invested in equity securities of small market capitalization
companies, which, for the purposes of the Small Company Value Fund, are those
companies with a market capitalization of $2 billion or less at the time of
purchase. While smaller companies generally have potential for rapid growth,
investments in smaller companies often involve greater risks than investments in
larger, more established companies because smaller companies may lack the
management experience, financial resources, product diversification, and

competitive strengths of larger companies. In addition, in many instances the
securities of smaller companies are traded only over-the-counter or on a
regional securities exchange, and the frequency and volume of
 
                                       11

<PAGE>

their trading is substantially less than is typical of larger companies. As a
result, the securities of smaller companies may be subject to greater and more
abrupt price fluctuations. When making larger sales of portfolio securities, the
Small Company Value Fund may have to sell such securities at discounts from
quoted prices or may have to make a series of small sales over an extended
period of time due to the trading volume of smaller company securities.
Investors should be aware that, based on the foregoing factors, an investment in
the Small Company Value Fund may be subject to greater price fluctuations than
an investment in a fund that invests primarily in larger, more established
companies. The Adviser's research efforts may also play a greater role in
selecting securities for the Small Company Value Fund than in a fund that
invests in larger, more established companies.
 
The Small Company Value Fund will pursue its investment objective by employing
the value-oriented investment approach. The Small Company Value Fund seeks
securities that appear to be underpriced and are issued by companies with proven
management, consistent earnings, sound finances and strong potential for market
growth. By investing in such companies, the Small Company Value Fund tries to
enhance the potential for appreciation and limit the risk of decline in the
value of its portfolio. The Small Company Value Fund focuses on the fundamentals
of each small-cap company instead of trying to anticipate what changes might
occur in the stock market, the economy, or the political environment. This
approach differs from that used by many other funds investing in small-cap
company stocks. Those funds often buy stocks of companies they believe will have
above-average earnings growth, based on anticipated future developments. In
contrast, the Small Company Value Fund's securities are generally selected with
the belief that they are currently undervalued, based on existing conditions and
that their earning power or franchise value does not appear to be reflected in
their current stock price. In addition, to further reduce risk, the Small
Company Value Fund diversifies its holdings among many companies and industries.
Other factors considered in the selection of securities include whether a
company has an established presence in its industry, a product or market niche
or whether management owns a significant stake in the company's operation.
 
The Small Company Value Fund may also invest in special situations, that is, in
securities the values of which may be affected by particular developments
unrelated to business conditions generally, and which may fluctuate without
relation to general market trends. In general, a special situation company is a
company whose securities could reasonably be expected to be accorded market
recognition within a foreseeable period of time at an appreciated value solely
by reason of a development particularly or uniquely applicable to that company.
The principal risk associated with investment in special situation companies is
that if the anticipated development does not occur, the investment is likely not
to appreciate or may decline. Examples of special situations are companies being
reorganized or merged, having unusual new products, enjoying particular tax
advantages, or acquiring new management. The Small Company Value Fund will not,

however, invest more than 10% of its assets (at the time of purchase) in equity
securities of companies (including predecessors) that have less than three years
of operations.
 
In addition to common stock and securities convertible into common stock, the
Small Company Value Fund may invest in preferred stock, investment grade debt
securities (including bonds, debentures, notes, asset and mortgage-backed
securities and convertible securities), U.S. Government Securities, municipal
securities (including general and special obligation securities and industrial
revenue bonds), money market instruments (such as commercial paper and bankers'
acceptances) and other financial instruments. (See 'Additional General
Investment Policies--Mortgage and Asset-Backed Securities' and 'Investment Grade
Debt Securities.') The Small Company Value Fund will not invest more than 35% of
its total assets in investment grade debt securities, each determined at the
time of purchase.
 
The Small Company Value Fund may invest in securities listed on a securities
exchange and securities traded in the over-the-counter markets. A greater
proportion of the securities in which the Fund invests may not be listed on any
national securities exchange as compared with an investment company that invests
primarily in securities of larger companies. Securities not listed on a national
securities exchange may be less liquid and more volatile than listed securities.
 
The Small Company Value Fund may purchase or sell options on individual
securities as well as on indices of securities as a means of achieving
additional return or of hedging the value of its portfolio. However, the Small
Company Value Fund will not purchase options if, as a result, the aggregate cost
of all outstanding options exceeds 10% of its assets. The Small Company Value
Fund may also purchase and sell financial futures contracts and options thereon
for hedging and risk management purposes. A financial futures contract is an
agreement to purchase or sell an agreed amount of securities at a set price for
delivery in the future. To the extent that puts, calls, straddles and similar
investment strategies involve instruments regulated by the Commodity Futures
Trading Commission, the Small Company Value Fund is limited to an investment not
in excess of 5% of its total assets.
 
   
The Small Company Value Fund may also (i) invest up to 20% of the value of its
total assets in foreign securities, (ii) invest up to 5% of its total assets in
rights or warrants, and (iii) invest no more than 10% of its net assets
(determined at the time of purchase) in instruments having no ready market,
provided that the Small Company Value Fund will not invest in restricted
securities.

WINTHROP FIXED INCOME FUND

    
 
The investment objective of the Winthrop Fixed Income Fund (the 'Fixed Income
Fund') is to provide as high a level of total return as is consistent with
capital preservation by investing principally in debt securities, including,
without limitation, convertible and nonconvertible debt securities of foreign
and domestic companies, including both well-known and established and new and
lesser-known companies. Total return means the sum of interest income, dividend
income (if any) and capital gains less capital losses. Capital preservation
means minimizing the risk of capital loss in a period of falling prices (rising
interest rates) for debt securities.
 
Specifically, the investment policies of the Fixed Income Fund permit it to
invest, without restriction, in the following types of securities:
 
 (1) Bonds, including municipal bonds (taxable and tax-exempt, including, among
     others, special and general obligation bonds and industrial development
     bonds) and other debt securities, which are rated Aaa, Aa, A or MIG-1 by
     Moody's Investors Service, Inc. ('Moody's'), or AAA, AA, A or SP-1 by
     Standard & Poor's Ratings Group ('S&P');
 
 (2) U.S. Government Securities;
 
 (3) Obligations issued or guaranteed by national or state bank holding
     companies, which obligations are not rated as a matter of policy by either
     Moody's or S&P, but which, in the opinion of the Adviser (on the basis of
     criteria believed by the Adviser to be comparable to that used by
     nationally recognized statistical rating organizations for assigning
     ratings), meet the Fixed Income Fund's investment objective; and
 
 (4) Commercial paper rated Prime-1 by Moody's or A-1 + or A-1 by S&P.
 
The Fixed Income Fund may also invest not more than 25% (in the aggregate) of
its total assets at the time of investment in (i) debt securities rated Baa or
MIG-2 by Moody's or BBB or SP-2 by S&P and (ii) commercial paper rated Prime-2
by Moody's or A-2 by S&P, to the extent that such investments would, in the
opinion of the Adviser, be consistent with the Fixed Income Fund's investment
objective. (See 'Additional General Investment Policies,' for a description of
securities rated BBB by S&P and Baa by Moody's and of asset and mortgage-backed
securities.)
 
The Fixed Income Fund may enter into repurchase agreements, terminable within
seven days or less, with respect to issues of the U.S. Treasury, with member
banks of the Federal Reserve System or primary dealers in U.S. Government
Securities, as long as such investments do not in the aggregate exceed 15% of
the total assets of the Fixed Income Fund (except where such investments are
made for temporary defensive purposes, in which case no limit is applicable).
 
As a matter of fundamental policy, which cannot be changed without approval by
the vote of a majority of the Fixed Income Fund's outstanding voting securities
(as defined in the Statement of Additional Information), the Fixed Income Fund
will invest at least 80% of the value of its total assets at the time of
investment in debt securities. In normal circumstances, the Fixed Income Fund
will invest at least 65% of the value of its total assets in fixed income

securities. However, the Fixed Income Fund reserves the right to hold cash and
short-term fixed income securities and to enter into repurchase agreements as
necessary for temporary defensive or emergency purposes as determined by the
Adviser without regard for the above limitations.
 
The Fixed Income Fund may also invest in restricted securities and in
instruments having no ready market if such purchases at the time thereof would
not cause more than 10% of the value of its net assets to be invested in not
readily marketable assets. (See 'Investment Restrictions.')
 
The Adviser intends to adjust the average maturity of the Fund's portfolio
depending upon its assessment of the relative yields on debt securities of
different maturities and its expectations of future interest rate patterns.
Because a change in the market value of a debt security generally is inversely
related to market interest rates, the market value of the Fixed Income Fund's
investments will tend to decrease during periods of rising interest rates and to
increase during periods of falling rates. The magnitude of the fluctuations in
the market value of the Fund's portfolio as a result of fluctuations in interest
rates will generally be greater at times when the average maturity of the Fund's
portfolio is longer. The Fixed Income Fund will invest and hold debt securities
which, in the opinion of the Adviser, will maximize the total return of the
portfolio.
 
   
WINTHROP MUNICIPAL TRUST FUND
    
 
The investment objective of the Winthrop Municipal Trust Fund (the 'Municipal
Trust Fund') is to provide as high a level of total return as is consistent with
capital preservation by investing principally in high grade tax-exempt municipal
securities. This investment objective, unlike most other municipal bond funds,
is not to provide current income which is exempt from federal and/or state
income tax. Total return means the sum of interest income and capital gains less
capital losses. The Municipal Trust Fund intends to distribute annually its net
capital gains. Any such distributions will be taxable to a shareholder as
capital gain. (See 'Dividends, Distributions and Taxes.')
 
The Municipal Trust Fund attempts to provide high total return by actively
managing the maturities of the bonds in the portfolio in response to the
Adviser's anticipation of the movement of interest rates and its assessment of
the relative yields. The Fund will shorten
 
                                       13

<PAGE>

the portfolio's maturities when the Adviser believes that interest rates will
rise and lengthen maturities when the Adviser believes that rates will fall.
Currently, the Fund invests primarily in securities to maintain an average
maturity of 10 years or less to help reduce the risk associated with long-term
bonds, as is consistent with its objective of capital preservation. To a lesser
extent, the Municipal Trust Fund will also attempt to enhance total return by
selecting municipal securities which the Adviser believes are undervalued. The
success of these strategies depends upon the Adviser's ability to accurately

forecast changes in interest rates and to properly assess the value of municipal
securities. The investor should be aware that there can be no assurances that
the Municipal Trust Fund's investment strategies will be successful.
 
Under normal circumstances, it is the Municipal Trust Fund's policy to invest at
least 80% of the value of its net assets at the time of investment in tax-exempt
municipal securities. However, the Municipal Trust Fund reserves the right to
hold cash and short-term fixed income securities and to enter into repurchase
agreements as necessary for temporary defensive or emergency purposes as
determined by the Adviser without regard for the above limitation.
 
The Municipal Trust Fund seeks to achieve its objective by investing primarily
in a diversified portfolio of high grade, intermediate term municipal
securities. Municipal securities fall into two principal classes: bonds and
notes which may have fixed, variable or floating rates of interest. The
investment policies of the Municipal Trust Fund permit it to invest, without
restriction, in tax-exempt municipal bonds and notes which are rated Aaa, Aa, A
or MIG-1 by Moody's or AAA, AA, A or SP-1 by S&P. For a more complete discussion
of Municipal Securities, see 'Additional General Investment Policies--Municipal
Securities.'
 
The Municipal Trust Fund may also invest not more than 25% (in the aggregate) of
its total assets at the time of investment in (i) municipal securities rated Baa
or MIG-2 by Moody's or BBB or SP-2 by S&P and (ii) commercial paper rated
Prime-2 by Moody's or A-2 by S&P, to the extent that such investments would, in
the opinion of the Adviser, be consistent with the Municipal Trust Fund's
investment objective. (See 'Additional General Investment Policies--Investment
Grade Debt Securities' for a description of securities rated BBB by S&P and Baa
by Moody's.) Non-rated municipal securities will also be considered for
investment by the Municipal Trust Fund when the Adviser believes that the
financial condition of the issuers of such obligations and the protection
afforded by the terms of the obligations themselves limit the risk to the
Municipal Trust Fund to a degree comparable to that of rated securities which
are consistent with the Municipal Trust Fund's objective and policies.
 
Because a change in the market value of a debt security generally is inversely
related to market interest rates, the market value of the Municipal Trust Fund's
investments will tend to decrease during periods of rising interest rates and to
increase during periods of falling rates. The magnitude of the fluctuations in
market value of the Municipal Trust Fund's portfolio as a result of fluctuations
in interest rates will generally be greater at times when the average maturity
of the Municipal Trust Fund's portfolio is longer.
 
The Municipal Trust Fund may enter into repurchase agreements, terminable within
seven days or less, with respect to issues of the U.S. Treasury, with member
banks of the Federal Reserve System or primary dealers in U.S. Government
Securities, as long as such investments do not in the aggregate exceed 15% of
the total assets of the Municipal Trust Fund (except where such investments are
made for temporary defensive purposes in which case no limit is applicable).
 
The Municipal Trust Fund may also invest in (i) restricted securities and in
instruments having no ready market if such purchases at the time thereof would
not cause more than 15% of the value of its net assets to be invested in not
readily marketable assets and (ii) municipal bonds that are subject to the

alternative minimum tax ('AMT-Subject Bonds').
 
Dividends of the Municipal Trust Fund will consist of income exempt from federal
income tax, income subject to the federal AMT, and taxable ordinary income and
capital gains. (See 'Dividends, Distributions and Taxes.')
 
See the Statement of Additional Information for a more complete description of
the Municipal Trust Fund's investment practices and the risks associated
therewith.

                            THE INTERNATIONAL FUNDS
        ---------------------------------------------------------------
 
   
WINTHROP DEVELOPING MARKETS FUND
    
 
The investment objective of the Winthrop Developing Markets Fund (the
'Developing Markets Fund') is to seek long-term growth of capital by investing
primarily in common stocks and other equity securities from developing
countries. Under normal market conditions, the Developing Markets Fund intends
to invest at least 65% of its total assets in the equity securities of
developing countries.
 
   
The Developing Markets Fund considers developing countries to be all countries
that are designated as developing or emerging countries by the International
Bank for Reconstruction and Development (the World Bank) or the International
Finance Corporation, as well as countries that are classified by the United
Nations or otherwise regarded by their authorities as developing. Currently,
countries not included in this category are Ireland, Spain, New Zealand,
Australia, the United Kingdom, Italy, the Netherlands, Belgium, Austria, France,
Canada, Germany, Denmark, the United States,
    
 
                                       14

<PAGE>

Sweden, Finland, Norway, Japan and Switzerland. As used in this Prospectus, a
company in a developing country is an entity: (i) for which the principal
securities trading market is in a developing country, as defined above or (ii)
organized under the laws of and with a principal office in a developing country.
 
As an operating policy, the Developing Markets Fund currently intends to invest
primarily in countries represented within the Morgan Stanley Capital
International ('MSCI') Emerging Market Indices. Those countries currently
include Argentina, Brazil, Chile, Colombia, Mexico, Peru, Venezuela, India,
Indonesia, Korea, Malaysia, Philippines, South Africa, Thailand, Sri Lanka,
Greece, Israel, Jordan, Pakistan, Poland, Portugal, Taiwan and Turkey. The
Adviser and the International Funds investment subadviser, AXA Asset Management
Partenaires (the 'Subadviser'), do not currently intend to invest more than 25%
of the Developing Markets Fund's total assets (at the time of investment) in

developing countries not represented within the MSCI Emerging Market Indices.
 
The Developing Markets Fund seeks to identify those countries and industries
where economic and political factors are likely to produce above average growth
rates. The Developing Markets Fund then seeks to invest in those companies in
such countries and industries that are best positioned and managed to take
advantage of these economic and political factors. The assets of the Developing
Markets Fund ordinarily will be invested in the securities of issuers in at
least three different developing countries.
 
Characteristics of developing countries that may affect investment in their
markets include certain national policies that may restrict investment by
foreigners and the absence of developed legal structures governing private and
foreign investments and private property. The typically small size of the
markets for securities issued by issuers located in developing countries and the
possibility of a low or nonexistent volume of trading in those securities may
also result in a lack of liquidity and in substantial price volatility of those
securities. Shareholders should be aware that investing in developing countries
involves exposure to economic structures that are generally less diverse and
mature, and to political systems which can be expected to have less stability
than those of developed countries.
 
   
WINTHROP INTERNATIONAL EQUITY FUND
    
 
The investment objective of the Winthrop International Equity Fund (the
'International Equity Fund') is to seek long-term growth of capital by investing
primarily in common stocks and other equity securities from established markets
outside the United States. Under normal market conditions, the International
Equity Fund intends to invest at least 65% of its total assets in equity
securities of issuers from at least three different countries outside the United
States. The International Equity Fund considers it consistent with this
objective to acquire securities of companies incorporated in the United States
and having their principal activities and interests outside of the United
States.
 
   
In pursuing its investment objective, the International Equity Fund intends to
diversify its equity investments primarily among countries represented within
the EAFE Index, also known as the Morgan Stanley Capital International Europe,
Australia, Far East index, an unmanaged index of over 1,000 foreign stock
prices. Those countries currently include Germany, the Netherlands, Belgium,
Austria, France, Italy, Spain, the United Kingdom, Switzerland, Japan, Hong
Kong, Australia, New Zealand, Malaysia, Singapore and the Scandinavian
countries. The Adviser and Subadviser do not currently intend to invest more
than 10% of the International Equity Fund's total assets (at the time of
investment) in countries outside the United States not represented within the
EAFE Index.
    
 
The International Equity Fund seeks to identify those countries and industries
with favorable growth prospects. The International Equity Fund then seeks to
invest in those companies in such countries and industries that are reasonably

valued with reliable earnings and high quality management.
 
ADDITIONAL INVESTMENT POLICIES OF THE INTERNATIONAL FUNDS Each International
Fund may invest up to 25% of its assets in convertible securities. The Adviser
and Subadviser currently do not intend to invest over 5% of each International
Fund's assets in convertible securities rated below investment grade by S&P and
Moody's, or convertible securities not rated by S&P or Moody's, unless believed
by the Adviser or Subadviser to be of comparable quality to instruments rated
investment grade by S&P or Moody's. The International Funds will not invest in
convertible securities rated below B by S&P or Moody's, or unrated convertible
securities of comparable quality. See the Appendix to the Statement of
Additional Information of the International Funds for the risks associated with
investing in convertible securities with such ratings. For a further discussion
on convertible securities, see 'Additional General Investment
Policies--Convertible Securities.'
 
The International Funds may purchase sponsored or unsponsored ADRs, EDRs and
GDRs (collectively, 'Depositary Receipts'). ADRs are Depositary Receipts
typically issued by a U.S. bank or trust company which evidence ownership of
underlying securities issued by a foreign corporation. EDRs and GDRs are
Depositary Receipts typically issued by foreign banks or trust companies,
although they also may be issued by U.S. banks or trust companies, and evidence
ownership of underlying securities issued by either a foreign or a United States
corporation.
 
Each International Fund may invest up to 15% of its net assets in illiquid
investments. In accordance with procedures adopted by the Trustees, the Adviser
and Subadviser determine the liquidity of an International Fund's investments.
The absence of a trading market
 
                                       15

<PAGE>

can make it difficult to ascertain a market value for illiquid investments.
Disposing of illiquid investments may involve time-consuming negotiation and
legal expenses, and it may be difficult or impossible for an International Fund
to sell them promptly at an acceptable price.
 
The International Funds reserve the right as a defensive measure to hold
temporarily other types of securities without limit, including commercial paper,
bankers' acceptances, short-term debt securities (corporate and government) or
government and high quality money market securities of U.S. and non-U.S.
issuers, repurchase agreements, time deposits or cash (foreign currencies or
U.S. dollars), in such proportions as, in the opinion of the Adviser or
Subadviser, prevailing market, economic or political conditions warrant. Each
International Fund may also temporarily hold cash and invest in high quality
foreign or domestic money market instruments up to 35% of its assets, pending
investment of proceeds from new sales of International Fund shares or to meet
ordinary daily cash needs.
 
Each International Fund may also (i) invest up to 35% of its total assets in
investment grade fixed income securities, (ii) invest up to 5% of its net assets
in warrants, (iii) purchase and sell put and call options, (iv) invest up to 15%

of its net assets in restricted securities or other instruments having no ready
market, (v) enter into forward foreign currency exchange contracts to protect
the value of its assets against future changes in the level of currency exchange
rates, (vi) purchase and sell financial futures contracts and options thereon
which are traded on a commodities exchange or board of trade for certain
hedging, return enhancement and risk management purposes in accordance with the
regulations of the Commodity Futures Trading Commission and (vii) purchase and
sell financial futures contracts and related options, without limitation, for
bona fide hedging purposes. Subject to the foregoing, the value of all financial
futures contracts sold will not exceed the total market value of each
International Fund's portfolio.
 
Because the markets for certain options and futures contracts in which the
International Funds will invest (including markets located in foreign countries)
are relatively new and still developing and may be subject to regulatory
restraints, each International Fund's ability to engage in transactions using
such investments may be limited.
 
For additional information on the use, risks and costs of the above referenced
policies and practices, see 'Additional General Investment Policies.'

        ---------------------------------------------------------------
                                THE MONEY FUNDS
        ---------------------------------------------------------------
 
   
WINTHROP MUNICIPAL MONEY FUND
    
 
The Winthrop Municipal Money Fund's (the 'Municipal Money Fund') investment
objective is to seek maximum current income, consistent with liquidity and
safety of principal, that is exempt from Federal income taxation to the extent
described below. As a matter of fundamental policy, the Municipal Money Fund
pursues its objectives by investing in high quality municipal securities having
remaining maturities of one year or less, which maturities may extend to 397
days, and at least 80% of the Municipal Money Fund's total assets will be
invested in such securities (as opposed to the taxable investments described
below). However, the Municipal Money Fund reserves the right to lower the
percentage to 65% if economic or political conditions warrant. To increase the
Municipal Money Fund's ability to reach its investment objectives, the dollar
weighted average maturity of its portfolio securities is always 90 days or less.
In general, securities with longer maturities are more vulnerable to price
changes, although they may provide higher yields. It is possible that a major
change in interest rates or a default on the Municipal Money Fund's investments
could cause their share prices to change.
 
Normally, substantially all the Municipal Money Fund's income will be tax-exempt
as described below. Such income may be subject to state or local and or Federal
AMT income taxes.
 
The municipal securities in which the Municipal Money Fund invests include
municipal notes and short-term municipal bonds which may have fixed, variable or
floating rates of interest. Municipal securities with variable rates may include
participation interests in industrial development bonds which may be backed by

letters of credit from banking or other financial institutions. The letters of
credit of any single of such institutions in respect of all variable rate
obligations will not cover more than the allowable percentage of the Municipal
Money Fund's total assets in accordance with Rule 2a-7 of the Investment Company
Act of 1940, as amended ('1940 Act'). For a more complete discussion of
Municipal Securities, see 'Additional General Investment Policies--Municipal
Securities.'
 
The Municipal Money Fund may also invest without limitation in tax-exempt
municipal securities subject to the AMT. (See 'Dividends, Distributions and
Taxes.')
 
All of the Municipal Money Fund's municipal securities at the time of purchase
are rated within the two highest quality ratings of Moody's (Aaa and Aa, MIG 1
and MIG 2 or VMIG1 and VMIG2) or S&P's (AAA and AA or SP-1 and SP-2), or judged
by the Adviser to be of comparable quality.
 
The Municipal Money Fund may also invest (i) up to 10% of its net assets in
stand-by commitments, delayed-delivery, when-issued securities and other
illiquid securities, (ii) more than 5% of its net assets in municipal leases,
which are leases or installment purchases used by state and local governments as
a means to acquire property, equipment or facilities without involving debt
issuance limitations and (iii) in taxable securities including obligations of
the U.S. Government and its agencies, high quality certificates
 
                                       16

<PAGE>

of deposit and bankers' acceptances, prime commercial paper, and repurchase
agreements.
 
To seek to reduce investment risk, the Municipal Money Fund may not invest in
the securities of any one issuer, except the U.S. Government, in excess of the
percentage of the Municipal Money Fund's total assets allowed under Rule 2a-7 of
the 1940 Act.
 
The Municipal Money Fund earns income at current money market rates, and its
yield will vary from day to day and generally reflects current short-term
interest rates and other market conditions. It is important to note that neither
the Municipal Money Fund nor its yield are insured or guaranteed by the U.S.
Government.
 
   
WINTHROP U.S. GOVERNMENT MONEY FUND
    
 
The Winthrop U.S. Government Money Fund's (the 'Government Fund') investment
objective is to seek maximum current income, consistent with liquidity and
safety of principal. As a matter of fundamental policy, the Government Fund
pursues its objectives by maintaining a portfolio of high quality money market
securities, including the types described in the succeeding paragraph, which at
the time of investment generally have remaining maturities of one year or less,
although maturities may extend to 397 days. The dollar weighted average maturity

of the Government Fund's portfolio securities will vary, but will always be 90
days or less. In general, securities with longer maturities are more vulnerable
to price changes, although they may provide higher yields. It is possible that a
major change in interest rates or a default on the Government Fund's investments
could cause their share prices to change.
 
The securities in which the Government Fund primarily invests are: (1) U.S.
Government Securities, including issues of the U.S. Treasury, such as bills,
certificates of indebtedness, notes and bonds, and issues of agencies and
instrumentalities established under the authority of an act of Congress,
including variable rate obligations such as floating rate notes; and (2)
repurchase agreements that are collateralized in full each day by eligible
mortgage related securities or the types of securities listed above. These
agreements are entered into with 'primary dealers' (as designated by the Federal
Reserve Bank of New York) in U.S. Government Securities and would create a loss
to the Government Fund if, in the event of a dealer default, the proceeds from
the sale of the collateral were less than the repurchase price. In addition, if
the seller of repurchase agreements becomes insolvent, the Government Fund's
right to dispose of the securities might be restricted.
 
The Government Fund may commit up to 10% of its net assets to the purchase of
illiquid securities, which includes when-issued U.S. Government Securities,
whose value may fluctuate prior to their settlement, thereby creating an
unrealized gain or loss to the Government Fund.
 
The Government Fund earns income at current money market rates and its yield
will vary from day to day and generally reflects current short-term interest
rates and other market conditions. It is important to note that neither the
Government Fund nor its yield is insured or guaranteed by the U.S. Government.
 
ADDITIONAL INVESTMENT POLICIES OF THE MONEY FUNDS To maintain portfolio
diversification and reduce investment risk, the Money Funds may not: (1) borrow
money except from banks on a temporary basis or via entering into reverse
repurchase agreements to be used exclusively to facilitate the orderly
maturation and sale of portfolio securities during any periods of abnormally
heavy redemption requests, if they should occur; such borrowings may not be used
to purchase investments; or (2) pledge, hypothecate or in any manner transfer,
as security for indebtedness, its assets except to secure such borrowings.
 
   
In addition to the above referenced securities, the Money Funds reserve the
right as a defensive measure to hold temporarily other types of securities which
are permitted by Rule 2a-7 of the 1940 Act. See 'Investment Policies and
Restrictions' in the Money Funds' Statement of Additional Information for a more
complete description of the Money Funds' objectives, strategies, instruments to
be used in connection therewith, and risks associated therewith.
    

        ---------------------------------------------------------------
                               ADDITIONAL GENERAL
        ---------------------------------------------------------------
                              INVESTMENT POLICIES
        ---------------------------------------------------------------
 

The following general investment policies supplement those set forth above for
each Fund.
 
   
EQUITY SECURITIES 'Equity Securities,' as used in this Prospectus, includes
common stock, preferred stock (including convertible preferred), bonds
convertible into common or preferred stock, rights and warrants, equity
interests in trusts and depositary receipts for equity securities.
    
 
CONVERTIBLE SECURITIES A convertible security is a bond or preferred stock which
may be converted at a stated price within a specified period of time into a
certain quantity of the common or preferred stock of the same or a different
issuer. Convertible securities have characteristics of both bonds and equity
securities. Like a bond, a convertible security tends to increase in market
value when interest rates decline and tends to decrease in market value when
interest rates rise. However, the price of a convertible security is also
influenced by the market value of the underlying stock. The price of a
convertible security tends to increase as the market value of the underlying
stock rises, whereas it tends to decrease as the market value of the underlying
stock declines.
 
WARRANTS A warrant gives the holder thereof the right to buy equity securities
at a specific price during a specified period of time. Warrants tend to be more
 
                                       17

<PAGE>

volatile than the underlying security, and if at a warrant's expiration date the
security is trading at a price below the price set in the warrant, the warrant
will expire worthless. Conversely, if at the expiration date the underlying
security is trading at a price higher than the price set in the warrant, the
holder of the warrant can acquire the stock at a price below its market value.
 
MORTGAGE AND ASSET-BACKED SECURITIES Except for the Municipal Trust Fund, the
Funds may invest in mortgage and asset-backed securities. 'Mortgage-backed
securities' are securities that directly or indirectly represent a participation
in, or are secured by and payable from, mortgage loans on real property,
including pass-through securities such as Ginnie Mae, Fannie Mae and Freddie Mac
Certificates. The yield and credit characteristics of mortgage-backed securities
differ in a number of respects from traditional fixed income securities. The
major differences typically include more frequent interest and principal
payments, usually monthly, and the possibility that prepayment of principal may
be made at any time. Prepayment rates are influenced by changes in current
interest rates and a variety of other factors. In general, changes in the rate
of prepayment on a security will change the yield to maturity of the security.
Under certain interest rate or prepayment rate scenarios, a Fund may fail to
recoup fully its investment in such securities notwithstanding the credit
quality of the issuers of such securities. As a result of usual prepayment
patterns, amounts available for reinvestment are likely to be greater during a
period of declining interest rates and, thus, are likely to be invested at lower
interest rates, than during a period of rising interest rates. Mortgage-backed
securities may decrease in value as a result of increases in interest rates and

may benefit less than other fixed income securities from declining interest
rates because of the risk of prepayment. Except for the Municipal Trust Fund,
the Funds may also invest in private mortgage pass-through securities. Such
securities are not guaranteed by the U.S. Government or its agencies or
instrumentalities.
 
'Asset-backed securities' have similar structural characteristics to
mortgage-backed securities, but the underlying assets include assets such as
motor vehicle installment sales or installment loan contracts, leases of various
types of real and personal property, and receivables from revolving credit
agreements, rather than mortgage loans or interests in mortgage loans.
Asset-backed securities present certain risks that are not present in
mortgage-backed securities; primarily, these securities do not have the benefit
of the same security interest in the related collateral. There is the
possibility that recoveries of repossessed collateral may not, in some cases, be
available to support payments on these securities.
 
MUNICIPAL SECURITIES Municipal securities fall into two principal classes: bonds
and notes. Municipal bonds, which are longer-term debt obligations meeting long-
term capital needs, fall into two general classifications: 'general obligation'
bonds or 'revenue' bonds. Payment of principal and interest on general
obligation bonds is secured by the issuing municipality's pledge of its full
faith, credit, and taxing power. Payment on revenue bonds is met from the
revenues obtained from a certain facility, class of facilities, special excise
or other tax, but not from general tax revenues. Variations on these two
classifications exist, such as revenue bonds backed by a municipality's general
taxing power, or general obligation bonds backed by limited taxing power.
Municipal notes are short-term debt obligations generally maturing in a year or
less, meeting short-term capital needs and are also either 'general obligation'
or 'revenue' debt securities. They include tax anticipation notes, revenue
anticipation notes, bond anticipation notes, construction loan notes and tax-
exempt commercial paper.
 
Municipal securities may have fixed, variable or floating rates of interest.
Variable and floating rate securities pay interest at rates that are adjusted
periodically, according to a specified formula, in order to minimize fluctuation
in the principal value of the securities. A 'variable' interest rate adjusts at
predetermined intervals (e.g., daily, weekly, or monthly), while a 'floating'
interest rate adjusts whenever a specified benchmark rate (such as the bank
prime lending rate) changes.
 
The Municipal Money Fund and Municipal Trust Fund may invest in variable rate
obligations. Such adjustments minimize changes in the market value of the
obligation, and accordingly, enhance the ability of the Municipal Money Fund to
maintain a stable $1.00 net asset value. (See 'Net Asset Value').
 
   
INVESTMENT GRADE DEBT SECURITIES The Focus Funds and International Funds may
invest in debt securities of investment grade quality. Investment grade debt
securities are debt securities rated in one of the four highest rating
categories by a nationally recognized statistical rating organization and
unrated debt securities believed by the Adviser (on the basis of criteria
believed by the Adviser to be comparable to that applied by such rating
agencies) to be of comparable quality to debt securities so rated. Debt

securities rated Baa or higher by Moody's or BBB or higher by S&P are investment
grade securities. Securities rated BBB are regarded by S&P as having an adequate
capacity to pay interest and repay principal; whereas such securities normally
exhibit adequate protection parameters, adverse economic conditions or changing
circumstances are more likely, in the opinion of S&P, to lead to a weakened
capacity to pay interest and repay principal for debt in this category than in
higher rated categories. Securities rated Baa by Moody's are considered by
Moody's to be medium grade obligations; they are neither highly protected nor
poorly secured; interest payments and principal security appear to be adequate
for the present but certain protective elements may be lacking or may be
characteristically

                       CHECKWRITING TERMS AND CONDITIONS
 
   
1. REDEMPTION AUTHORIZATION: The Signatory(s) whose signature(s) appear on the
reverse side, intending to be legally bound, hereby agree each with the other
and with UMB Bank, n.a. (Bank) that the Bank is appointed agent for such
person(s) and, as such agent, is directed to request FPS Services, Inc., the
Transfer Agent of the Winthrop Money Funds (each a Fund and collectively the
Funds), to redeem shares of the Fund registered in the name of such Signatory(s)
upon receipt of, and in the amount of, checks drawn upon the above numbered

expressly authorized to commingle such proceeds in this account with the
proceeds of the redemption of the shareholders of the Fund. The Signatory(s)
understand that the Bank may also act as an agent and custodian for the Fund.
The Bank and Transfer Agent are expressly authorized to honor checks as
redemption instructions hereunder and may require signature guarantees in
accordance with the policies stated in the Prospectus, but neither the Fund's
Transfer Agent, the Bank, the Funds, the Funds' Adviser nor any clearing agent
of the foregoing shall be liable for any loss or liability resulting from the
absence of any such guarantee.
    
 
2. CHECK PAYMENT: The Signatory(s) authorize and direct the Bank to pay each
check presented hereunder, subject to all laws and Bank rules and regulations
pertaining to checking accounts. In addition, the Signatory(s) agree that: (a)
No check shall be issued or honored, or any redemption effected, in an amount
less than stated in the Prospectus; (b) No check shall be issued or honored, or
redemption effected, for any amounts represented by shares unless payment for
such shares has been made in full and any checks given in such payment have been
collected through normal banking channels; (c) No check shall be honored unless
the Fund has provided the Bank, from the proceeds of redemption or otherwise,
collected funds for the payment of such check; (d) Checks issued hereunder
cannot be cashed over the counter at the Bank; and (e) Checks shall be subject

Prospectus.

 
5. HEIRS AND ASSIGNS: These terms and conditions shall bind the respective
heirs, executors, administrators and assigns of the Signatory(s).

unreliable over any great length of time; in the opinion of Moody's, they lack
outstanding investment characteristics and in fact have speculative
characteristics as well. For a more complete description of Moody's and S&P's
ratings, see the Appendix to the Statement of Additional Information of each of
the Funds.
    
 
The investment grade limitations referenced for each Fund are applicable at the
time of initial investment and the Fund may determine to retain securities the
issuers of which have had their credit characteristics downgraded.
 
REPURCHASE AGREEMENTS The Funds may enter into 'repurchase agreements' with
respect to U.S. Government Securities. The Funds may enter into repurchase
agreements with member banks of the Federal Reserve System or 'primary dealers'
(as designated by the Federal Reserve Bank of New York) in such securities.
Repurchase agreements permit a Fund to keep all of its assets at work while
retaining 'overnight' flexibility in pursuit of investments of a longer-term
nature. Winthrop requires continual maintenance of collateral with a Fund's
custodian in an amount equal to, or in excess of, the market value of the
securities which are the subject of a repurchase agreement. In the event a
vendor defaults on its repurchase obligation, the Fund might suffer a loss to
the extent that the proceeds from the sale of the collateral were less than the
repurchase price. If the vendor becomes the subject of bankruptcy proceedings,
the Fund might be delayed in selling the collateral.
 
FOREIGN SECURITIES The International Funds will, and the Focus Funds except for
the Municipal Trust Fund may, invest in foreign securities. There are certain
risks involved in investing in foreign securities which are not the usual risks
inherent in U.S. investments. These risks include those resulting from
fluctuations in currency exchange rates, revaluation of currencies, future
adverse political and economic developments and the possible imposition of
currency exchange blockages or other foreign governmental laws or restrictions,
reduced availability of public information concerning issuers and the lack of
uniform accounting, auditing and financial reporting standards or of other
regulatory practices and requirements comparable to those applicable to domestic
companies. Additionally, foreign securities may be adversely affected by
fluctuations in value of one or more currencies relative to the U.S. dollar.
Moreover, securities of many foreign companies may be less liquid and their
prices more volatile than those of securities of comparable U.S. companies. In
addition, with respect to certain foreign countries, there is the possibility of
expropriation, nationalization, confiscatory taxation and limitations on the use
or removal of funds or other assets of a foreign issuer, including the
withholding of dividends. Foreign securities may be subject to foreign
government taxes that would reduce the net yield on such securities. To the
extent a fund invests in securities denominated or quoted in currencies other
than the U.S. dollar, changes in foreign currency exchange rates will affect the
value of portfolio securities and the appreciation or depreciation of

investments. Investment in foreign securities may also result in higher expenses
due to the cost of converting foreign currency into U.S. dollars, the payment of
fixed brokerage commissions on foreign exchanges, which generally are higher
than commissions on U.S. exchanges, and the expense of maintaining securities
with foreign custodians.
 
INVESTMENT COMPANIES Pursuant to the 1940 Act, a fund generally may invest up to
10% of its total assets in the aggregate in shares of other investment companies
and up to 5% of its total assets in any one investment company as long as each
investment does not represent more than 3% of the outstanding voting stock of
the acquired investment company at the time of investment. Investment in other
investment companies may involve the payment of substantial premiums above the
value of such investment companies' portfolio securities and is subject to
limitations under the 1940 Act and market availability. The International Funds
or the Municipal Money Fund may invest in such investment companies if, in the
judgment of the Advisers or Subadviser, the potential benefits of such
investment justify the payment of any applicable premium or sales charge. As a
shareholder in an investment company, the Municipal Money Fund or an
International Fund would bear its ratable share of that investment company's
expenses, including its advisory and administrative fees. At the same time the
Municipal Money Fund or an International Fund would continue to pay its own
management fees and other expenses.
 
OPTIONS Each of the Growth Fund and the Growth and Income Fund may write covered
call options (as discussed below) on individual securities or stock indices, but
only in order to minimize the effect of a market decline in the value of
securities in its portfolio. The Small Company Value Fund may purchase or sell
put and call options on individual securities or stock indices as a means of
achieving additional return or of hedging the value of its portfolio. The
International Funds may purchase and sell put and call options on securities,
currencies and financial indices that are traded on U.S. or foreign securities
exchanges or in the over-the-counter market. (Options traded in the over-
the-counter market are considered illiquid investments.)
 
A call option is a contract that gives the holder of the option the right, in
return for a premium paid, to buy from the seller the security underlying the
option at a specified exercise price at any time during the term of the option
or, in some cases, only at the end of the term of the option. The seller of the
call option has the obligation upon exercise of the option to deliver the
underlying security upon payment of the exercise price. A put option is a
contract that gives the holder of the option the right, in return for a premium,
to sell to the seller of the option the underlying security at a
 
                                       19

<PAGE>

specified price. The seller of the put, on the other hand, has the obligation to
buy the underlying security upon exercise at the exercise price. The purchaser
of an option risks a total loss of the premium paid for the option if the price
of the underlying security does not increase or decrease sufficiently to justify
exercise. The seller of an option, on the other hand, will recognize the premium
as income if the option expires unexercised but forgoes any capital appreciation
in excess of the exercise price in the case of a call option and may be required

to pay a price in excess of current market value in the case of a put option.
Options purchased and sold in private transactions (other than on an exchange)
also impose on a fund the credit risk that the counterparty will fail to honor
its obligations.
 
An option is considered 'covered' for purposes of the Funds' investment
limitations if the party writing it owns, at all times during the option period,
either (i) the optioned securities, or securities convertible into or carrying
rights to acquire the optioned securities at no additional cost, or (ii) an
offsetting call option on the same securities at the same or lower price.
 
The success of a Fund's transactions with options depends on the ability of the
Adviser or Subadviser to predict the direction of the market and is subject to
certain additional risks, including generally greater volatility of options as
compared to common stocks and the risk that an option will expire without value.
 
   
RISKS OF OPTIONS, CURRENCY EXCHANGE CONTRACTS AND FINANCIAL FUTURES
STRATEGIES Participation in the options or futures markets and in currency
exchange transactions involves investment risks and transaction costs to which a
Fund would not be subject absent the use of these strategies. If the Adviser's
or Subadviser's predictions of movements in the direction of the securities,
foreign currency and interest rate markets are inaccurate, the adverse
consequences to a Fund may leave the Fund in a worse position than if such
strategies were not used. The loss from entering into futures contracts is
potentially unlimited. Risks inherent in the use of options, foreign currency
and futures contracts and options on futures contracts include (1) dependence on
the investment manager's ability to predict correctly movements in the direction
of interest rates, securities prices and currency markets; (2) imperfect
correlation between the price of options and futures contracts and options
thereon and movements in the prices of the securities or currencies being
hedged; (3) skills needed to use these strategies which are different from those
needed to select portfolio securities; (4) the possible absence of a liquid
secondary market for any particular instrument at any time; (5) the possible
need to defer closing out certain hedged positions to avoid adverse tax
consequences; and (6) the possible inability of a Fund to purchase or sell a
portfolio security at a time that otherwise would be favorable for it to do so,
or the possible need for a Fund to sell a portfolio security at a
disadvantageous time, due to the need for such Fund to maintain 'cover' or to
segregate securities in connection with hedging transactions. See 'Dividends,
Distributions and Taxes' in the Statement of Additional Information of each
Fund.
    
 
WHEN ISSUED, DELAYED DELIVERY SECURITIES AND FORWARD COMMITMENTS The Funds may,
to the extent consistent with their other investment policies and restrictions,
enter into forward commitments for the purchase or sale of securities, including
on a 'when issued' or 'delayed delivery' basis in excess of customary settlement
periods for the type of security involved. In some cases, a forward commitment
may be conditioned upon the occurrence of a subsequent event, such as approval
and consummation of a merger, corporate reorganization or debt restructuring,
i.e., a when, as and if issued security. When such transactions are negotiated,
the price is fixed at the time of the commitment, with payment and delivery
taking place in the future, generally a month or more after the date of the

commitment. While the Funds will only enter into a forward commitment with the
intention of actually acquiring the security, the Funds may sell the security
before the settlement date if it is deemed advisable.
 
Securities purchased under a forward commitment are subject to market
fluctuations, and no interest (or dividends) accrues to a Fund prior to the
settlement date. The Funds will segregate with their custodian cash or other
liquid, unencumbered assets, in an aggregate amount at least equal to the amount
of their respective outstanding forward commitments.
 
   
STAND-BY COMMITMENTS The Municipal Trust Fund and the Municipal Money Fund may
invest in stand-by commitments which may involve certain additional expenses.
The custodian of each of these Funds will maintain a segregated account
containing liquid securities having value equal to, or greater than, such
securities. The price of such securities, which is generally expressed in yield
terms, is fixed at the time the commitment to purchase is made, but delivery and
payment for such securities takes place at a later time. Normally the settlement
date occurs within ten days to one month after the purchase of the issue. The
value of such securities may fluctuate prior to their settlement, thereby
creating an unrealized gain or loss to the Fund. Such securities are examples of
what the SEC considers 'illiquid securities' because their settlement date
occurs more than seven days after their purchase. The SEC limits money market
funds to hold only up to 10% of their net assets for securities which settle
more than seven days after purchase.
    
 
INVESTMENT RESTRICTIONS
 
Certain investment restrictions applicable to each Fund are fundamental policies
and may not be changed with respect to a Fund without the approval of a majority
of the shareholders of that Fund. See 'Investment Policies and Restrictions' in
the applicable Fund's Statement of Additional Information.

The Focus Funds pay a fee to WSWMC at the following annual percentage rates of
the average daily net assets of each Focus Fund: Growth Fund, .750 of 1% of the
first $100,000,000, .500 of 1% of the balance; Small Company Value Fund, .875 of
1% of the first $100,000,000, .750 of 1% of the next $100,000,000 and .625 of 1%
of net assets in excess of $200,000,000; Fixed Income Fund, .625 of 1% of the
first $100,000,000, .500 of 1% of the balance; Municipal Trust Fund, .625 of 1%
of the first $100,000,000, .500 of 1% of the balance; and Growth and Income

advisory fees to be paid by the Growth Fund, the Small Company Value Fund and
the Growth and Income Fund are higher than those paid by many other mutual funds
with similar investment objectives.
 
   
Pursuant to the Advisory Agreement, the Growth Fund has paid WSWMC an advisory
fee equivalent to .75% of the average daily net assets for the year ended
October 31, 1997. The Growth Fund's total operating expenses of $1,202,263 for
such period amounted to 1.36% of the average daily net assets of its Class A
shares and 2.06% of the average daily net assets of its Class B shares.
    
 
   
Pursuant to the Advisory Agreement, the Growth and Income Fund has paid WSWMC an
advisory fee equivalent to .63% of the average daily net assets for the year
ended October 31, 1997. The Growth and Income Fund's total operating expenses of
$1,866,864 for such period amounted to 1.22% of the average daily net assets of
its Class A shares and 1.92% of the average daily net assets of its Class B
shares.
    
 
   
Pursuant to the Advisory Agreement, the Small Company Value Fund has paid WSWMC
an advisory fee equivalent to .77% of the average daily net assets for the year
ended October 31, 1997. The Small Company Value Fund's total operating expenses
of $3,573,073 for such period amounted to 1.35% of the average daily net assets
of its Class A shares and 2.05% of the average daily net assets of its Class B
shares.
    
 
   
Pursuant to the Advisory Agreement, the Fixed Income Fund has paid WSWMC an
advisory fee equivalent to .625% of the average daily net assets for the year
ended October 31, 1997. The Fixed Income Fund's total operating expenses for
such period were $749,718. For the period November 1, 1997 through April 30,
1998 WSWMC has agreed to reduce its management fees and reimburse expenses by
the amount that total fund operating expenses exceed 1.00% of the average daily
net assets of Class A shares and 1.70% of the average daily net assets of Class
B shares of the Fixed Income Fund. After April 30, 1998, WSWMC may continue or
it may determine to discontinue this practice. As a result of the voluntary

assumption of expenses, WSWMC reimbursed the Fund $164,718 during the year ended
October 31, 1997. Absent such reimbursement, the Fixed Income Fund's total
operating expenses for the year ended October 31, 1997 would have amounted to
1.30% of the average daily net assets of its Class A shares and 2.00% of the
average daily net assets of its Class B shares.
    
 
   
Pursuant to the Advisory Agreement, the Municipal Trust Fund has paid WSWMC an

assets of the Fund's Class A shares and 1.20% of the average daily net assets of
the Fund's Class B shares. For the period June 3, 1997 through April 30, 1998,
WSWMC has agreed to reduce its management fees and reimburse operating expenses
by the amount that total fund operating expenses exceed 1.00% of the average
daily net assets of the Fund's Class A shares and 1.70% of the average daily net
assets of the Fund's Class B shares. After April 30, 1998, with respect to the
Municipal Trust Fund, the Adviser may, in its sole discretion, determine to
continue to pay certain expenses of the Fund or it may discontinue this
practice. As a result of the voluntary assumption of expenses, the Adviser
reimbursed the Fund $269,050 during the year ended October 31, 1997. Absent such
reimbursement, the Municipal Trust Fund's total operating expenses for such
period would have amounted to 1.44% of the average daily net assets of its Class
A shares and 2.14% of the average daily net assets of its Class B shares.
    
 
The International Funds pay a fee to WSWMC at the following annual percentage
rates of the average daily net assets of each International Fund: 1.25% of the
first $100,000,000, 1.15% of the next $100,000,000 and 1.00% of net assets in

Under the Subadvisory Agreement, WSWMC pays the Subadviser for its services, out
of the Adviser's own resources, at the following annual percentage rates of the
average daily net assets of each International Fund: .625% of each International
Fund's first $100,000,000, .575% of the next $100,000,000 and .50% of the
balance.
 
   
For the year ended October 31, 1997, pursuant to the Advisory Agreement, the
International Funds paid WSWMC advisory fees equivalent to 1.25% of the average
daily net assets of each Fund. The total operating expenses of the International
Equity Fund and the Developing Markets Fund for such period were $1,176,144 and
$1,047,363, respectively. Commencing at the inception of the International Funds
through April 30, 1998, WSWMC and the Subadviser have agreed to voluntarily
reduce their management fees by the amount that total operating expenses exceed

2.15% and 2.90% of the average daily net assets of the Class A and Class B
shares, respectively, of each International Fund. Any such reduction will be
borne equally between the Adviser and Subadviser. After April 30, 1998, WSWMC
and the Subadviser may, in their sole discretion, determine to discontinue this
practice with respect to either International Fund. As a result of the voluntary
assumption of expenses, the Adviser reimbursed the International Equity Fund
$88,653 and the Developing Markets Fund $139,596 during the year ended October
31, 1997. Absent such reimbursement, the International Equity Fund's total
operating expenses for such period would have amounted to 2.33% of the average
daily net assets of its Class A shares and 3.08% of the average daily net assets
of its Class B shares and the Developing Markets Fund's total operating expenses
for such period would have amounted to 2.49% of the average daily net assets of
its Class A shares and 3.24% of the average daily net assets of its Class B
shares.
    
 
The Money Funds pay a fee of .40% of the average daily net assets of each Money
Fund to DLJIM, which is reduced to .35% of each Money Fund's average daily net
assets in excess of $1 billion. The advisory fees to be paid by the Money Funds
are similar to those paid by other money market mutual funds.
 
   
For the period from the inception of the Money Funds on February 24, 1997
through October 31, 1997, pursuant to the Advisory Agreement, the Money Funds
paid DLJIM advisory fees equivalent to .40% (annualized) of the average daily
net assets of each Fund. The total operating expenses of the Municipal Money
Fund and the U.S. Government Money Fund for such period were $260,693 and
$230,350, respectively. Commencing at the inception of the Money Funds through
April 30, 1998, DLJIM has agreed to reduce its management fees and DLJIM or its
affiliates have agreed to reimburse operating expenses by the amount that total
operating expenses exceed .90% of the average daily net assets of each Money
Fund. After April 30, 1998, DLJIM or its affiliates may, in their discretion,
determine to discontinue this practice with respect to either Money Fund. As a
result of the voluntary assumption of expenses, the Adviser reimbursed the
Municipal Money Fund $80,308 and the U.S. Government Money Fund $76,506 during
the period from the inception of the Money Funds on February 24, 1997 through
October 31, 1997. Absent such reimbursement, the Municipal Money Fund's and the
U.S. Government Money Fund's total operating expenses for such period would have
amounted to 1.30% and 1.35%, respectively, of the average daily net assets of
each Fund.
    

        ---------------------------------------------------------------
                              EXPENSES OF WINTHROP
        ---------------------------------------------------------------
 
GENERAL
 
In addition to payments to each Fund's Adviser under the investment advisory
agreements described above, Winthrop pays the other expenses incurred in its
organization and operations, including the costs of printing prospectuses and
other reports to existing shareholders; all expenses and fees related to
registration and filing with the SEC and with state regulatory authorities;
custody, transfer and dividend disbursing expenses; legal and auditing costs;

clerical, accounting, and other office costs; fees and expenses of Trustees who
are not affiliated with the Advisers or Subadviser; costs of maintenance of
existence; and interest charges, taxes, brokerage fees, and commissions. As to
the obtaining of clerical and accounting services not required to be provided to
the Focus Funds by WSWMC under the investment advisory agreement, Winthrop may
employ its own personnel. For such services, it also may utilize personnel
employed by the Adviser or by its affiliates. In such event, the services shall
be provided to the Focus Funds at cost and the payments therefor must be
specifically approved in advance by the Focus Funds' Trustees, including a
majority of its disinterested Trustees. Under the terms of the investment
advisory agreements with the International Funds and the Money Funds, management
supervision and assistance and office facilities, in addition to administrative
and nonadviser services provided to the Adviser or their affiliates, may be
reimbursed.
 
DISTRIBUTION AGREEMENT
 
Rule 12b-1 adopted by the SEC under the 1940 Act permits an investment company
directly or indirectly to pay expenses associated with the distribution of its
shares. Under SEC regulations, some of the payments described below to be made
by Winthrop could be deemed to be distribution expenses within the meaning of
such rule. Thus, pursuant to Rule 12b-1, the Trustees of each Fund (including a
majority of its disinterested Trustees) have adopted separate 12b-1 Plans for
expenses incurred in distributing Class A shares (the '12b-1 Class A Plans') and
Class B shares (the '12b-1 Class B Plans') of the Focus Funds and
 
                                       23

<PAGE>

International Funds and in distributing shares of the Money Funds ('Money Fund
12b-1 Plans' and collectively, the '12b-1 Plans'). Winthrop, on behalf of each
Fund, has entered into a Distribution Agreement (the 'Agreements') with
Donaldson, Lufkin & Jenrette Securities Corporation, Winthrop's distributor (the
'Distributor'). The Distributor may enter into service agreements with other
entities. The Distributor is located at 277 Park Avenue, New York, New York
10172.
 
In adopting the 12b-1 Plans, the Trustees of each Fund determined that there is
a reasonable likelihood that the 12b-1 Plans may benefit such Fund and its
shareholders.
 
With respect to each Focus Fund, the maximum amount payable under the 12b-1
Class A Plans is .30 of 1% of the average daily net assets of the Class A shares
during the year consisting of (i) an asset-based sales charge of .05 of 1% of
the average daily net assets of the Class A shares and (ii) a service fee of up
to .25 of 1% of the average daily net assets of the Class A shares. With respect
to each International Fund, the maximum amount payable under the Rule 12b-1
Class A Plans is .25 of 1% of the average daily net assets of the Class A shares
during the year. Under the 12b-1 Class B Plans, the maximum amount payable by
each Fund is 1% of the average daily net assets of the Class B shares during the
year consisting of (i) an asset-based sales charge of up to .75 of 1% of the
average daily net assets of the Class B shares and (ii) a service fee of up to
 .25 of 1% of the average daily net assets of the Class B shares. The Agreements,

but not the Rule 12b-1 Plans, will terminate in the event of their assignment.
 
With respect to each Money Fund, the maximum amount payable by the Money Funds
under the Money Fund 12b-1 Plans for distributing shares is .40 of 1% of the
average daily net assets of each Money Fund during the year. The current amount
payable by the Money Funds under the Money Fund 12b-1 Plans to the Distributor
is .25 of 1% of the average daily net assets of each Money Fund during the year.
Pursuant to the Money Fund's Agreement, the Trustees can raise the distribution
fees up to the maximum amount by a majority vote if the Trustees, in their
opinion, feel that the raise is in the best interest of the Money Funds and
their shareholders. The Agreements, but not the Money Fund 12b-1 Plans, will
terminate in the event of their assignment.
 
   
With respect to the Money Fund 12b-1 Plans and the 12b-1 Class A Plans and 12b-1
Class B Plans plans for the International Funds (the 'International Fund 12b-1
Plans'), amounts paid by the Money and International Funds are used in their
entirety to reimburse the Distributor for actual expenses incurred. In contrast,
under the 12b-1 Class A Plans, and 12b-1 Class B Plans for the Focus Funds (the
'Focus Fund 12b-1 Plans'), each Focus Fund is obligated to pay distribution
and/or service fees to the Distributor as compensation for its distribution and
service activities, not as reimbursement for specific expenses incurred. If the
Distributor's expenses exceed its distribution and service fees, the Fund will
not be obligated to pay any additional expenses. If the Distributor's expenses
are less than such distribution and service fees, it will retain its full fees
and realize a profit.
    
 
Amounts paid under the 12b-1 Plans and the Agreements are used in their entirety
to pay the Distributor for expenses incurred to (i) promote the sale of shares
of each Fund by, for example, paying for the preparation, printing and
distribution of prospectuses, sales brochures and other promotional materials
sent to prospective shareholders, by directly or indirectly purchasing radio,
television, newspaper and other advertising or by compensating the Distributor's
employees or employees of the Distributor's affiliates for their distribution
assistance, (ii) make payments to the Distributor to compensate broker-dealers
or other persons for providing distribution assistance and (iii) make payments
to compensate financial intermediaries for providing administrative and
accounting services with respect to Winthrop's shareholders.
 
With respect to sales of Class B shares through a broker-dealer, the
broker-dealer is paid a concession at the time of sale. In addition, an ongoing
maintenance fee may be paid to broker-dealers on sales of shares of the Funds.
The payments to the broker-dealer, although a Fund expense which is paid by all
shareholders, will only directly benefit investors who purchase their shares
through a broker-dealer rather than directly from the Funds. Broker-dealers who
sell shares of the Funds may provide services to their customers that are not
available to investors who purchase their shares directly. Investors who
purchase their shares directly from a Fund will pay a pro rata share of such
Fund's expenses of encouraging broker-dealers to provide such services but will
not receive any of the direct benefits of such services. The payments to the
broker-dealers will continue to be paid for as long as the related assets remain
in the Fund.
 

   
The International Fund 12b-1 Plans and the Money Fund 12b-1 Plans permit
payments to be made in subsequent years for expenses incurred in prior years if
the Funds' Trustees specifically authorize such payment. As of the year ended
October 31, 1997, the amounts eligible for payment in subsequent years were
$254,632 and $307,866 for the Developing Markets Fund and the International
Equity Fund, respectively, which represents .74% and .60% of the Fund's October
31, 1997 net assets, respectively, and $31,414 and $25,145 for the Municipal
Money Fund and the U.S. Government Money Fund, respectively, which represents
0.08% and 0.07% of the Funds' October 31, 1997 net assets, respectively.
    
 
   
The table below shows distribution costs charged to each Fund during the past
fiscal year or, in the case of the Municipal Money Fund and U.S. Government
Money Fund, during the period from the Funds'

Under the Agreements, the Adviser may make payments to the Distributor from the
Adviser's own resources, which may include the management fees paid by Winthrop.
 
In addition to the concession and maintenance fee paid to dealers or agents, the
Distributor will from time to time pay additional compensation to dealers or
agents in connection with the sale of shares. Such additional amounts may be
utilized, in whole or in part, in some cases together with other revenues of
such dealers or agents, to provide additional compensation to registered
representatives of such dealers or agents who sell shares of the Fund. On some
occasions, such compensation will be conditioned on the sale of a specified
minimum dollar amount of the shares of the Funds during a specific period of
time. Such incentives may take the form of payment for meals, entertainment, or
attendance at educational seminars and associated expenses such as travel and
lodging. Such dealer or agent may elect to receive cash incentives of equivalent
amounts in lieu of such payments.

PURCHASES
 
Shares of the Funds will be offered on a continuous basis directly by the Funds
and by the Distributor, acting as agent for the Funds, at the respective net
asset value per share determined as of the close of the regular trading session
of the New York Stock Exchange (the 'NYSE'), currently 4:00 p.m., New York City
time, following receipt of a purchase order in proper form plus, in the case of
Class A shares of each Focus Fund and International Fund, an initial sales
charge imposed at the time of purchase or, subject to a contingent deferred
sales charge upon (i) redemption of Class B shares of each Focus Fund and
International Fund, (ii) certain redemptions of Class A shares of each Focus
Fund and International Fund and (iii) certain redemptions of shares of each
Money Fund. The investor should send a completed Share Purchase Application
(found in this Prospectus) and enclose a check in the amount of the initial
investment to the Transfer Agent, FPS Services, Inc., P.O. Box 61503, King of
Prussia, PA 19406-0903, Attn: Winthrop Mutual Funds. (For overnight courier

Drive). The account will be established once the application and check are
received in good order. Checks should be made payable to 'Winthrop Mutual
Funds.' Checks made payable to the shareholder or another third party (third
party checks) will not be accepted for investment in Winthrop.
 
To open a new account by wire, first call Winthrop Mutual Funds at
1-800-225-8011 (option #2) to obtain an account number. A representative will
instruct you to send a completed, signed application to the Transfer Agent.
Accounts cannot be opened without a completed, signed application and a fund
account number. Contact your bank to arrange a wire transfer to:
 
   
      UMB Bank, n.a.
      ABA #10-10-00695

      For: FPS Services, Inc.
      A/C #98-7037-0719
      Attn: Winthrop Mutual Funds
    
 
      Your wire instructions must also include:
 
     -- the name of the Fund in which the money
        is to be invested,
      --your account number at the Fund, and
      --the name(s) of the account holder(s).
 
Investors who purchase shares of the Money Funds through a wire transfer will be
eligible to receive the daily dividend declared on the date of purchase if the
Transfer Agent is notified of such purchase by 12:00 Noon and wired funds are
received by the Transfer Agent by 4:00 p.m. (See 'Dividends, Distributions and
Taxes.')
 
Investors may also open Winthrop accounts via their securities dealer. In
addition, securities dealers may offer an automatic sweep for the shares of the
Money Funds in the operation of cash accounts for its customers. Shares of the
Money Funds purchased through an automatic sweep by 1:00 p.m. are eligible to
receive that day's daily dividend. Contact your securities dealer to determine
if a sweep is available and what the sweep parameters are.
 
The initial minimum investment in each Fund is $250 and $25 for subsequent
investments in a Fund. (For example, an investor wishing to make an initial
investment in shares of two Funds would be required to invest at least $250 in
each Fund.) Full and fractional shares will be credited to an investor's account
in the amount of the investment. Share certificates will not be issued for full
or fractional shares of the Money Funds. Each Fund reserves the right to reject
any initial or subsequent investment in its sole discretion. Shareholder
accounts established on behalf of the following types of plans will be exempt
from the Fund's minimum initial investment and minimum subsequent investment
requirements: (i) retirement
 
                                       25

plans qualified under section 401(k) of the Code; (ii) plans described in
section 403(b) of the Code; (iii) deferred compensation plans described in
section 457 of the Code; (iv) simplified employee pension (SEP) plans; and (v)
savings incentive match plans for employees (SIMPLE) plans. With respect to
Class B shares of an International Fund or Focus Fund, an investor's maximum
purchase of such shares is $250,000.
 
Existing shareholders wishing to purchase additional shares of a Fund may use
the investment stub found at the bottom of the Funds' Shareholder Statement form
or, if one is not available, they may send a check payable to such Fund directly
to Winthrop's Transfer Agent, FPS Services, Inc. at the address indicated on the
back cover of this Prospectus. Any check for additional shares sent directly to
Winthrop should reference the account number to which it should be credited.
Existing shareholders may also purchase additional shares of a Fund via a wire

transfer by contacting and providing the Fund account information to the
Transfer Agent and following the wire instructions above.
 
Further information and assistance is available by contacting Winthrop at the
address or telephone number listed on the back cover of this Prospectus.
 
REDEMPTIONS
 
Shares of Winthrop may be redeemed at a redemption price equal to the net asset
value per share, as next computed following the receipt in proper form by
Winthrop of shares tendered for redemption, less any applicable contingent
deferred sales charge in the case of Class B shares and certain redemptions of
Class A shares and certain redemptions of shares of the Money Funds.
 
The value of a shareholder's shares on redemption may be more or less than the
cost of such shares to the shareholder, depending upon the value of the Fund's
portfolio securities at the time of such redemption or repurchase. (See
'Dividends, Distributions and Taxes' for a discussion of the tax consequences of
a redemption.)
 
To redeem shares for which no share certificates have been issued, the
registered owner or owners should forward a letter to Winthrop's Transfer Agent,
FPS Services, Inc. containing a request for redemption of such shares at the
next determined net asset value per share. Alternatively, the shareholder may
elect the right to redeem shares by telephone. (See 'Additional Shareholder
Services--Telephone Redemption and Exchange Privilege'). The address of the
Transfer Agent can be found on the back cover of this Prospectus.
 
If the total value of the shares being redeemed exceeds $50,000 (before
deducting any applicable contingent deferred sales charge) or a redemption
request directs proceeds to a party other than the registered account owner(s),
the signature or signatures on the letter or the endorsement must be guaranteed
by an 'eligible guarantor institution' as defined in Rule 17Ad-15 under the
Securities Exchange Act of 1934. Eligible guarantor institutions include banks,
brokers, dealers, credit unions, national securities exchanges, registered
securities associations, clearing agencies and savings associations. A
broker-dealer guaranteeing signatures must be a member of a clearing corporation
or maintain net capital of at least $100,000. Credit unions must be authorized
to issue signature guarantees. Signature guarantees will be accepted from any
eligible guarantor institution which participates in a signature guarantee
program. Additional documents may be required for redemption of corporate,
partnership or fiduciary accounts.
 
The requirement for a guaranteed signature is for the protection of the
shareholder in that it is intended to prevent an unauthorized person from
redeeming his shares and obtaining the redemption proceeds.
 
   
Winthrop may request in writing that a shareholder whose account in a Fund has
an aggregate balance of less than $250 increase his or her account to at least
that amount within 60 days. If the shareholder fails to do so, Winthrop reserves
the right to close such account and send the proceeds to the shareholder. IRAs
and other qualified retirement accounts are not subject to mandatory redemption.
A Fund will not redeem involuntarily any shareholder account with an aggregate

balance of less than $250 based solely on the market movement of such Fund's
shares.
    
 
The right of redemption may not be suspended or the date of payment upon
redemption postponed for more than seven days after shares are tendered in
proper form for redemption, except for any period during which the NYSE is
closed (other than customary weekend and holiday closings) or during which
trading on the exchange is deemed to be restricted under rules of the SEC, or
for any period during which an emergency (as determined by the SEC) exists as a
result of which disposal by Winthrop of its portfolio securities is not
reasonably practicable, or as a result of which it is not reasonably practicable
for Winthrop to determine the value of its net assets, or for such other period
as the SEC may by order permit for the protection of shareholders. Generally,
redemptions will be made by payment in cash or by check. (See the Statement of
Additional Information.)
 
For information concerning circumstances in which redemptions may be effected
through the delivery of in kind portfolio securities, see the Statement of
Additional Information.

On purchases of $1,000,000 or more, there is no initial sales charge; the

Distributor may pay the dealer a fee of up to 1% as follows: 1% on purchases up
to $2 million, plus .80% on the next $1 million up to $3 million, .50% on the
next $47 million up to $50 million, .25% on purchases over $50 million. In
addition, Class A shares issued upon conversion of other shares of the Fund are
not subject to an initial sales charge.
 
From time to time, the Distributor may re-allow the full amount of the sales
charge to brokers as a commission for sales of such shares.
 
   
In addition, investors may be charged a fee by a securities dealer if they
effect transactions through a broker or agent.

     retirement plan for the benefit of any such person or relative; or the
     estate of any such person or relative, if such sales are made for
     investment purposes (such shares may not be resold except to the Funds). To
     qualify, the Distributor or Transfer Agent must be notified at the time of
     purchase;
 
 (5) shares purchased by registered investment advisors on behalf of fee-based
     accounts or by broker-dealers that have sales agreements with the Funds and
     which shares have been purchased on behalf of wrap fee client accounts and
     for which such registered investment advisors or broker-dealers perform
     advisory, custodial, record keeping or other services;
 

   
 (6) shares purchased as a client of DLJdirect Inc., a subsidiary of the
     Distributor.
    
 
   
 (7) shareholders who received shares in Winthrop as a result of the merger of
     Neuwirth Fund, Inc., Pine Street Fund, Inc. or deVegh Mutual Fund, Inc.,
     and who have maintained their investment in such shares of Winthrop; and
    
 
   
 (8) shares purchased for the following types of retirement plan accounts: (i)
     retirement plans qualified under section 401(k) of the Code; (ii) plans
     described in section 403(b) of the Code and (iii) deferred compensation
     plans described in section 457 of the Code.
    
 
   
 (9) Class B Shares which are automatically converted to Class A Shares. See
     'Automatic Conversion of Class B Shares.'
    
 
REDUCED SALES CHARGES
 
A reduction of sales charge rates in the tables above may be obtained for
participants in any of the following discount programs. These programs allow an
investor to receive a reduced offering price based upon the assets held or
pledged by the investor. The term 'investor' refers to (i) an individual, (ii)
an individual and spouse purchasing shares of the Fund for their own account or
for the trust or custodial accounts of their minor children, or (iii) a
fiduciary purchasing for any one trust, estate or fiduciary account, including
employee benefit plans of a single employer.

LETTER OF INTENT By initially investing at least $250 and submitting a Letter of
Intent to the Funds' Distributor or Transfer Agent, an investor may purchase
shares of Winthrop over a 13-month period at the reduced sales charge applying
to the aggregate amount of the intended purchases stated in the Letter. The
Letter may apply to purchases made up to 90 days before the date of the Letter.
However, the reduced sales charge would not apply to such purchases. It is the
investor's responsibility to notify the Transfer Agent at the time the Letter is
submitted that there are prior purchases that may apply.
    
 
5% of the total amount to be invested pursuant to the Letter will be held in
escrow by the Transfer Agent until the investment contemplated by the Letter is
completed within the 13-month period. The 13-month period begins on the date of
the earliest purchase. If the intended investment is not completed, the Transfer
Agent will redeem an appropriate number of the escrowed shares in order to

realize the difference between the sales charge on the shares purchased at the
reduced rate and the sales charge applicable to the total shares purchased.
 
RIGHT OF ACCUMULATION For investors who already have an account with the Funds,
reduced sales charges based upon the Funds' sales charge schedule are applicable
to subsequent purchases. The sales charge on each additional purchase is
determined by adding the current market value of the shares the investor
currently owns to the amount being invested. The Right of Accumulation is
illustrated by the following example:
 
If a previous purchase currently valued in the amount of $50,000 had been made
subject to a sales charge and the shares are still held, a current purchase of
$50,000 will qualify for a reduced sales charge (i.e. the sales charge on a
$100,000 purchase).
 
The reduced sales charge is applicable only to current purchases. It is the
investor's responsibility to notify the Transfer Agent at the time of subsequent
purchases that the account is eligible for the Right of Accumulation.
 
To be entitled to a reduced sales charge based upon shares already owned, the
investor must notify the Distributor or the Transfer Agent at the time of the
purchase that he wishes to take advantage of such entitlement, and give the
numbers of his accounts and those accounts held in the name of his spouse or for
minor children, the age of any such child and the specific relationship of each
such person to the investor.
 
CONCURRENT PURCHASES To qualify for a reduced sales charge, the investor may
combine concurrent purchases of shares purchased in any Winthrop Fund. For
example, if the investor concurrently invests $25,000 in one Fund and $25,000 in
another, the sales charge would be reduced to reflect a $50,000 purchase. In
order to exercise the Concurrent Purchases privilege, the investor must notify
the Distributor or Transfer Agent prior to his or her purchase.
 
COMBINED PURCHASE PRIVILEGE By combining the investor's holdings of shares in
any Winthrop Fund, the investor can reduce the initial sales charges on any
additional purchases of Class A shares. The investor may also use these
combinations under a Letter of Intent. This allows the investor to make
purchases over a 13-month period and qualify the entire purchase for a reduction
in initial sales charges on Class A shares. A combined purchase of $1,000,000 or
more may trigger the payment of a dealer's commission and the applicability of a
Limited CDSC. (See 'Contingent Deferred Sales Charge on Class A Shares.')
 
REINSTATEMENT PRIVILEGE The Reinstatement Privilege permits shareholders to
reinvest the proceeds of each Fund's Class A shares redeemed, within 120 days
from the date of redemption, without an initial sales charge. It is the
investor's responsibility to notify the Transfer Agent prior to his or her
purchase in order to exercise the Reinstatement Privilege. In addition, a CDSC
paid to Winthrop will be eligible for reimbursement at the current net asset
value of the applicable Fund if a shareholder reinstates his Winthrop account
holdings within 120 days from the date of redemption.
 
CONTINGENT DEFERRED SALES CHARGE ON CLASS B SHARES
 
A shareholder can purchase Class B shares at net asset value without an initial

sales charge. However, a shareholder may pay a CDSC if such shareholder redeems
within four years after purchase. The CDSC will be assessed on an amount equal
to the lesser of the then current net asset value or the original purchase price
of the Class B shares being redeemed. Accordingly, no Class B CDSC will be
imposed on amounts representing increases in net asset value above the initial
purchase price of the shares identified for redemption. In determining the Class
B CDSC, Class B shares are redeemed in the following order: (i) those acquired
pursuant to reinvestment of dividends or distributions, (ii) those held for over
four years, and (iii) those held longest during the four-year period.
 
Where the CDSC is imposed, the amount of the CDSC will depend on the number of
years since the shareholder made the purchase according to the table below.

recognized by a shareholder on the redemption of shares.
 
The CDSC on Class B shares will be waived for the following shareholders or
transactions:
 
 (1) shares received pursuant to the exchange privilege which are currently
     exempt from a contingent deferred sales charge;
 
 (2) redemptions as a result of shareholder death or disability (as defined in
     the Internal Revenue Code of 1986, as amended) (the 'Code');
 
 (3) redemptions made pursuant to Winthrop's systematic withdrawal plan pursuant
     to which up to 1% monthly or 3% quarterly of an account (excluding dividend
     reinvestments) may be withdrawn, provided that no more than 10% of the
     total market value of an account may be withdrawn over any 12 month period
     (shareholders who elect systematic withdrawals on a semi-annual or annual
     basis are not eligible for the waiver); and
 
 (4) liquidations, distributions or loans from the following types of retirement

     plan accounts: (i) retirement plans qualified under section 401(k) of the
     Code; (ii) plans described in section 403(b) of the Code and (iii) deferred
     compensation plans described in section 457 of the Code.
 
Redemptions effected by the Funds pursuant to their right to liquidate a
shareholder's account with a current net asset value of less than $250 will not
be subject to the CDSC.
 
   
In addition, investors may be charged a fee by a securities dealer if they
effect transactions through a broker or agent.
    
 
CONTINGENT DEFERRED SALES CHARGE ON CLASS A SHARES
 
A Limited Contingent Deferred Sales Charge ('Limited CDSC') will be imposed by
the Funds upon certain redemptions of Class A shares (or shares into which such
Class A shares are exchanged) made within 12 months of purchase, if such
purchases were made at net asset value and triggered the payment by the
Distributor of the dealer's commission described above (i.e., purchases of
$1,000,000 or more).
 
The Limited CDSC will be paid to the Distributor and will be equal to the lesser
of 1% of (i) the net asset value at the time of purchase of the Class A shares
being redeemed or (ii) the net asset value of such Class A shares at the time of
redemption. For purposes of this formula, the 'net asset value at the time of
purchase' will be the net asset value at the time of purchase of such Class A
shares even if those shares are later exchanged, and, in the event of an
exchange of such Class A shares, the 'net asset value of such shares at the time
of redemption' will be the net asset value of the shares into which the Class A
shares have been exchanged.
 
Redemptions of such Class A shares held for more than 12 months will not be
subjected to the Limited CDSC, and an exchange of such Class A shares will not
trigger the imposition of the Limited CDSC at the time of such exchange. The
period a shareholder owns shares into which Class A shares are exchanged will
count towards satisfying the 12-month holding period. The Funds will assess the
Limited CDSC if such 12-month period is not satisfied irrespective of whether
the redemption triggering its payment is of the Class A shares of the Funds or
shares into which the Class A shares have been exchanged.
 
In determining whether a Limited CDSC is payable, it will be assumed that shares
not subject to the Limited CDSC are the first redeemed followed by other shares
held for the longest period of time. The Limited CDSC will not be imposed upon
shares representing reinvested dividends or upon amounts representing share
appreciation. All investments made during a calendar month, regardless of when
during the month the investment occurred, will age one month on the last day of
that month and each subsequent month.
 
The Limited CDSC will be waived for the shareholders and transactions described
above as eligible for waiver under 'Contingent Deferred Sales Charge on Class B
Shares' and 'Sales at Net Asset Value.'
 
CONTINGENT DEFERRED SALES CHARGE ON CONVERTED SHARES--FOCUS FUNDS

 
Class A shares issued upon conversion of shares of a Focus Fund purchased prior
to February 28, 1996 ('Converted Shares') will be subject to the same contingent
deferred sales charge with the same terms as the Converted Shares were subject
to at the time of purchase. This CDSC is similar in all respects to the CDSC
charged on Class B shares except that the CDSC will not be imposed if the amount
redeemed is obtained from increases in the value of the account in a Fund
(whether from appreciation or reinvestment of dividends and capital gains
distributions) above the amounts of purchase payments during the past four
years.
 
For purposes of the CDSC on Class A shares issued upon conversion of Converted
Shares, it is assumed that the redemption is made from the earliest purchase
payment from which a redemption (or exchange) has not already been effected.
Therefore, redemptions will first be made from increases in the value of the
account without imposition of a CDSC and then, if necessary, from the shares
which have been held the longest.
 
Because the CDSC on Class A shares issued upon conversion of Converted Shares is
based on dollar value rather than number of shares, it may be imposed even if
the number of shares in the investor's account has increased through
reinvestment of dividends and capital gains distributions.
 
                                       29

<PAGE>

The CDSC on Class A shares issued upon conversion of Converted Shares will be
waived for the following shareholders or transactions:
 
 (1) investment advisory clients of the Advisers;
 
   
 (2) officers, directors and full-time employees and Trustees of Winthrop, the
     Advisers and Related Entities; or the relatives of any such person, or any
     trust or individual retirement account or self-employed retirement plan for
     the benefit of any such person or relative; or the estate of any such
     person or relative, if such sales are made for investment purposes (such
     shares may not be resold except to Winthrop);
    
 
   
 (3) certain employee benefit plans for employees of the Advisers and Related
     Entities;
    
 
 (4) an agent or broker of a dealer that has a sales agreement with the
     Distributor, for their own account or an account of a relative of any such
     person, or any trust or individual retirement account or self-employed
     retirement plan for the benefit of any such person or relative; or the
     estate of any such person or relative, if such sales are made for
     investment purposes (such shares may not be resold except to the Funds). To
     qualify, the Distributor or Transfer Agent must be notified at the time of
     purchase;

 
 (5) shares purchased by registered investment advisers or by broker-dealers
     that have sales agreements with the Funds and which shares have been
     purchased on behalf of wrap fee client accounts and for which such
     registered investment advisers or broker-dealers charge a fixed fee and
     perform advisory, custodial, record keeping or other services.
 
   
 (6) shareholders of Neuwirth Fund, Inc., Pine Street Fund, Inc. and deVegh
     Mutual Fund, Inc., which were diversified, no-load open-end management
     investment companies to which WSWMC provided investment advisory services;
    
 
 (7) liquidations, distributions or loans from the following types of retirement
     plans established on or after February 1, 1995: (i) retirement plans
     qualified under section 401(k) of the Code; (ii) plans described in section
     403(b) of the Code; and (iii) deferred compensation plans described in
     section 457 of the Code;
 
 (8) redemptions as a result of shareholder death or disability (as defined in
     the Code); and
 
 (9) redemptions made pursuant to Winthrop's systematic withdrawal plan up to 1%
     monthly or 3% quarterly of the account's total purchase payments (excluding
     dividend reinvestment) not to exceed 10% of total purchase payments over
     any 12 month rolling period (systematic withdrawals elected on a
     semi-annual or annual basis are not eligible for the waiver).
 
Redemptions effected by Winthrop pursuant to its right to liquidate a
shareholder's account with a current net asset value of less than $250 will not
be subject to the CDSC.
 
AUTOMATIC CONVERSION OF CLASS B SHARES
 
Class B shares held for eight years after purchase will be automatically
converted into Class A shares. Winthrop will effect conversions of Class B
shares into Class A shares only four times in any calendar year, on the last
business day of the second full week of March, June, September and December
(each, a 'Conversion Date'). If the eighth anniversary after a purchase of Class
B shares falls on a Conversion Date, an investor's Class B shares will be
converted on that date. If the eighth anniversary occurs between Conversion
Dates, an investor's Class B shares will be converted on the next Conversion
Date after such anniversary. Consequently, if a shareholder's eighth anniversary
falls on the day after a Conversion Date, that shareholder will have to hold
Class B shares for as long as an additional three months after the eighth
anniversary after purchase before the shares will automatically convert into
Class A shares.
 
All such automatic conversions of Class B shares will constitute a tax-free
exchange for federal income tax purposes.
 
ADDITIONAL SHAREHOLDER SERVICES
 
EXCHANGE PRIVILEGE Shares of one class of a Fund can be exchanged for the same

class of another Fund. Shareholders whose initial investment was directly into a
Money Fund may exchange such shares into either class of the International Funds
or the Focus Funds. Shares of each Money Fund established pursuant to Winthrop's
exchange privilege will be eligible for exchange into the International Funds or
Focus Funds provided that the exchange is directed into the same class of shares
upon which the initial investment was made. Unless otherwise indicated in the
initial Share Purchase Application or by written notice to Winthrop or its
Transfer Agent, shareholders whose initial investment was invested directly into
a Money Fund will, upon an exchange request, automatically be exchanged into
Class A shares of the requested International Fund or Focus Fund. Exchanges may
be made by mail or telephone. (See 'Telephone Redemption and Exchange
Privilege'.) The exchange privilege for all the Funds is available only in
states in which shares of the relevant Fund may be legally sold. An exchange is
effected on the basis of each Fund's relative net asset value per share next
computed following receipt of an order for such exchange from the shareholder.
 
Class A shares subject to a contingent deferred sales charge as described in
'Contingent Deferred Sales Charge on Class A Shares,' and 'Contingent Deferred
Sales Charge on Converted Shares--Focus Funds,' and
 
                                       30

<PAGE>

   
Class B shares which are exchanged will continue to be subject to the same
contingent deferred sales charge at the same rate and for the same period of
time as they were prior to exchange. A shareholder will pay a higher 12b-1 fee
when exchanging (i) shares of the Money Funds or Class A shares of the
International Funds (.25 of 1% annually) for Class A shares of the Focus Funds
(.30 of 1% annually) or (ii) shares of the Money Funds for Class B shares of the
International Funds or Focus Funds (1% annually).
    
 
   
Winthrop imposes no separate charge for exchanges. However, a shareholder may be
subject to an initial sales charge upon exchanging shares of a Money Fund for
Class A shares of the International Funds or Focus Funds. (See 'Purchases,
Redemptions and Shareholder Services--Initial Sales Charge.') A shareholder will
not be assessed any contingent deferred sales charge at the time of an exchange
between the Funds. Any applicable contingent deferred sales charge will be
assessed when the shareholder redeems shares of a Fund or from an account
established pursuant to Winthrop's exchange privilege in the Money Funds or
Alliance Money Market Funds. The period of time during which a shareholder owns
shares in any of the Funds will be credited to such shareholders holding period
in determining the applicable contingent deferred sales charge, if any. However,
the period of time during which a shareholder's funds are held in the Alliance
Money Market Funds will not be included in the holding period used to determine
the applicable contingent deferred sales charge. In addition, investors may be
charged a fee on exchanges that are effected through a securities dealer.
    
 
   
The exchange privilege is intended to provide shareholders with a convenient way

to switch their investments when their objectives or perceived market conditions
suggest a change. Winthrop reserves the right to reject any exchange request or
otherwise modify, restrict or terminate the exchange privilege at any time upon
at least 60 days prior written notice. The exchange privilege is not meant to
afford shareholders a means to play short term swings in the stock market by
engaging in frequent transactions in and out of the Funds. Shareholders who in
the opinion of the Adviser engage in such frequent transactions may be
prohibited from or restricted in placing future exchange orders.
    
 
Exchanges of shares are subject to the other requirements of the Fund into which
exchanges are made. Annual fund operating expenses for such Fund may be higher
and a sales charge differential may apply. Shareholders should be aware that an
exchange is treated for federal income tax purposes as a sale and a purchase of
shares which may result in recognition of a gain or loss.
 
AUTOMATIC MONTHLY INVESTMENT PLAN  A shareholder may elect on the Share Purchase
Application to make additional investments in a Fund automatically by
authorizing Winthrop to draw on the shareholder's bank account.
 
A shareholder may change the date (either the 10th, 15th or 20th of each month)
or amount (subject to a minimum of $25) of the shareholder's monthly investment
at any time by letter to Winthrop at least three business days before the change
becomes effective. The plan may be terminated at any time without penalty by the
shareholder or Winthrop.
 
AUTOMATIC EXCHANGE PLAN  Shareholders may authorize Winthrop to exchange an
amount established in advance automatically for shares of the same class of
another series of Winthrop or for shares of the Money Funds on a monthly,
quarterly, semi-annual or annual basis under an Automatic Exchange Plan. The
minimum exchange into another Fund under the Automatic Exchange Plan is $50.
These exchanges are subject to the terms of the Exchange Privilege described
above. See 'Additional Shareholder Services--Exchange Privilege.'
 
DIVIDEND DIRECTION OPTION  A shareholder may elect on the Share Purchase
Application to have his or her dividends paid to another individual or directed
for reinvestment within the same class of another series of Winthrop or into the
Money Funds provided that an existing account in such other Fund is maintained
by the shareholder.
 
   
SYSTEMATIC WITHDRAWAL PLAN  Any shareholder who owns or purchases shares of a
Fund having a current net asset value of at least $10,000 may establish a
Systematic Withdrawal Plan under which the shareholder or a third party will
receive payment by check in a stated amount of not less than $50 on a monthly,
quarterly, semi-annual or annual basis. A contingent deferred sales charge which
may otherwise be imposed on a withdrawal redemption will be waived in connection
with redemptions made pursuant to Winthrop's Systematic Withdrawal Plan up to 1%
monthly or 3% quarterly of an account (excluding dividend reinvestment) not to
exceed 10% over any 12-month rolling period. Systematic withdrawals elected on a
semi-annual or annual basis are not eligible for the waiver. See 'Purchases,
Redemptions and Shareholder Services.'
    
 

CHECKWRITING PRIVILEGES.  Shareholders of the Money Funds may redeem shares by
writing checks against their account balance for at least $100. Investments in
the Money Funds will continue to earn dividends until a shareholder's check is
presented to the Money Funds for payment. Checks will be returned by the
Transfer Agent if there are insufficient shares to meet the withdrawal amount.
Shareholders should not attempt to close an account by check because the exact
balance at the time the check clears will not be known when the check is
written. There is currently no charge to shareholders for checkwriting, but the
Money Funds reserve the right to impose a charge in the future. The Money Funds
may modify, suspend or terminate checkwriting privileges at any time upon notice
to shareholders and will terminate checkwriting privileges without notice for
accounts whose assets are exchanged
 
                                       31

<PAGE>

   
completely out of the Money Funds. In addition, UMB Bank, n.a., as agent for the
Transfer Agent in processing redemptions via the checkwriting privilege,
reserves the right to terminate checkwriting privileges at any time without
notice to shareholders. Checkwriting privileges will not be available for
accounts whose shares are subject to a contingent deferred sales charge.
    
 
TELEPHONE REDEMPTION AND EXCHANGE PRIVILEGE  A shareholder may elect on the
Share Purchase Application to be eligible to make withdrawals from such
shareholder's account via telephone orders (toll free (800) 225-8011) given to
Winthrop by the shareholder or the shareholder's investment dealer of record.
The maximum amount of such withdrawals is $50,000 per day. A shareholder may
also transfer assets via telephone from such shareholder's account to purchase
shares of another Fund. Winthrop will employ reasonable procedures to confirm
that instructions communicated by telephone are genuine. Such procedures include
the requirement that redemption or transfer orders must include the account name
and the account number as registered with Winthrop. The minimum amount for a
wire transfer is $1,000. Proceeds of telephone redemptions may also be sent by
automated clearing house funds to a shareholder's designated bank account.
Neither Winthrop, the Advisers, nor any transfer agent for any of the foregoing
will be responsible for following instructions communicated by telephone that
are reasonably believed to be genuine; accordingly, investors bear the risk of
loss. The Telephone Exchange Privilege will be offered automatically unless a
shareholder declines such option on the Share Purchase Application or by writing
to the Fund's Transfer Agent at the address listed on the back cover of this
Prospectus.
 
TIMING OF REDEMPTIONS AND EXCHANGES  If a redemption or transfer order for a
Fund is received on a Fund Business Day prior to the close of the regular
session of the NYSE, which is generally 4:00 p.m. New York City time, the
proceeds will be transferred as soon as possible (in accordance with industry
settlement procedures), and shares of each Fund will be priced that Fund
Business Day. If the redemption or transfer order is received after the close of
the regular session of the NYSE, shares of each Fund will be priced the next
Fund Business Day and the proceeds will be transferred as soon as possible after
such pricing (also in accordance with industry settlement procedures). A

shareholder also may request that proceeds be sent by check to a designated
bank. Transfers are made without any charge by Winthrop.
 
   
With respect to the Money Funds, if you wish to have Federal funds wired the
same day as your telephone redemption request, make sure that your request will
be received by the Money Funds prior to 12:00 Noon-Eastern Time. (See
'Additional Shareholder Services-- Telephone Redemption and Exchange
Privilege.') If a shareholder's securities dealer offers an automatic sweep
service, the sweep will automatically transfer from the Money Fund account
sufficient cash to cover any debit balance that may occur in your cash account.
Shares of the Money Funds redeemed prior to 1:00 p.m. through an automatic sweep
service will be eligible for same day federal funds wiring.
    
 
Purchases by check may not be redeemed by a Fund until after a reasonable time
necessary to verify that the purchase check has been paid (approximately ten
Fund Business Days from receipt of the purchase check). When a purchase is made
by wire and subsequently redeemed, the proceeds from such redemption normally
will not be transmitted until two Fund Business Days after the purchase by wire.
Bank acknowledgment of payment initialed by the shareholder may shorten delays.
 
Additional information concerning these Additional Shareholder Services may be
obtained by contacting Winthrop at the address or telephone number listed on the
back cover of this Prospectus.

        ---------------------------------------------------------------
                                NET ASSET VALUE
        ---------------------------------------------------------------
 
   
The net asset value per share for purchases and redemptions of shares of each
Fund is determined as of the close of the regular session of the NYSE, which is
generally 4:00 p.m. New York City time, on each day that trading is conducted
during such session on the NYSE. In accordance with the Funds' Agreement and
Declaration of Trust and By-Laws, net asset value for each Fund is determined
separately for each class, if applicable, by dividing the value of each class's
assets allocable to such class, less its liabilities, by the total number of
each class's shares then outstanding. With regard to the Money Funds, Winthrop
currently offers only one class of shares. All expenses, including investment
advisory fees, are accrued daily.
    
 
For purposes of this computation, the securities in each portfolio of the Focus
and International Funds are, except as described below, valued at their current
market value determined on the basis of market quotations or, if such quotations
are not readily available, such other method as the applicable Trustees believe
in good faith would accurately reflect their fair value.
 
For the Money Funds, the net asset value is expected to be maintained at a
constant $1.00 per share although this price is not guaranteed. For purposes of
this computation, the securities in each Money Fund's portfolio are valued at
amortized cost, which minimizes the effect of changes in a security's market
value and helps maintain a stable $1.00 per share price.

 
Short-term securities purchased within the Focus Funds or International Funds
which mature in more than 60 days are valued based on current market quotations.
Short-term securities which mature in 60 days or less are valued at amortized
cost, if their original maturity was 60 days or less, or by amortizing their
value on
 
                                       32

<PAGE>

the 61st day prior to maturity, if their original term to maturity exceeded 60
days, where it has been determined in good faith under procedures approved by
the applicable Trustees that amortized cost equals fair value.
 
For net asset value determination purposes, the value of a foreign security is
determined as of the close of trading on the foreign exchange on which it is
traded and that value is then converted into U.S. dollars at the foreign
exchange rate in effect as of the close of trading (4:00 p.m.) London time on
the day the value of the foreign security is determined. As a result, to the
extent a Fund holds securities quoted or denominated in a foreign currency,
fluctuations in the value of such currencies in relation to the U.S. dollar will
affect the net asset value of such Fund's shares even though there has not been
any change in the value of such securities as quoted in the foreign currency.
 
Foreign securities trading may not take place on all days on which the NYSE is
open. Further, trading takes place in various foreign markets on days on which
the NYSE is not open. Accordingly, the determination of the net asset value of
an International Fund's shares may not take place contemporaneously with the
determination of the prices of investments held by such International Fund.
Events affecting the values of investments that occur between the time their
prices are determined and 4:00 P.M. on each day that the NYSE is open will not
be reflected in the net asset value of an International Fund's shares unless the
Adviser or Subadviser, under the supervision of such International Fund's Board
of Trustees, determines that the particular event would materially affect net
asset value. As a result, the net asset value of an International Fund's shares
may be significantly affected by such trading on days when a shareholder has no
access to such International Fund.

        ---------------------------------------------------------------
                            DIVIDENDS, DISTRIBUTIONS
        ---------------------------------------------------------------
                                   AND TAXES
        ---------------------------------------------------------------
 
Each of the Funds has qualified and intends to qualify in the future as a
regulated investment company under Subchapter M of the Internal Revenue Code, so
that it will not be liable for federal income taxes to the extent that its net
taxable income and net capital gains are distributed. Annual statements as to
the current Federal tax status of distributions, if applicable, are mailed to
shareholders by January 31 each year.
 
Winthrop intends to distribute to shareholders of the Growth Fund, the Small
Company Value Fund and the International Funds on an annual basis and to

shareholders of the Growth and Income Fund on a quarterly basis substantially
all of such respective periods' net investment income, if any, for the
respective Funds. Dividends from net investment income on shares of the Money
Funds, Fixed Income Fund and Municipal Trust Fund are declared daily and paid
monthly. For purposes of this calculation, net investment income consists of all
accrued interest income on fund assets less the fund's expenses applicable to
that dividend period.
 
There is no fixed dividend rate, and there can be no assurance that a Fund will
distribute any net investment income. The amount of any distribution paid by
each Fund depends upon the realization by the Fund of income from that Fund's
investments. All distributions will be made to shareholders of a Fund solely
from assets of that Fund. Capital gains (short-term and long-term), if any,
realized by each of the Funds during a fiscal year of Winthrop will be
distributed to the respective shareholders shortly after the end of such fiscal
year.
 
Distributions may be subject to certain state and local taxes.
 
Each income dividend and capital gains distribution, if any, declared by
Winthrop on the outstanding shares of any Fund will, at the election of each
shareholder, be paid in cash or reinvested in additional full and fractional
shares of that Fund. An election to receive dividends and distributions in cash
or shares is made at the time of the initial investment and may be changed by
notice received by Winthrop from a shareholder or the shareholder's investment
dealer of record at least 30 days prior to the payable date for a particular
dividend or distribution on shares of each Fund. There is no charge in
connection with the reinvestment of dividends and capital gains distributions.
Such dividends and capital gains distributions, to the extent they would
otherwise be taxable, will be taxable to shareholders regardless of whether paid
in cash or reinvested in additional shares.
 
Distributions to shareholders out of tax-exempt interest income earned by the
Municipal Trust Fund and the Municipal Money Fund ('Exempt-Interest Dividends')
are not subject to federal income tax if, at the close of each quarter of each
Fund's taxable year, at least 50% of the value of each Fund's total assets
consists of tax-exempt obligations. Both Funds intend to meet this requirement.
Because the Municipal Trust Fund and Municipal Money Fund can invest in taxable
municipal bonds and other taxable securities as well as tax-exempt municipal
bonds, the portion of its dividends exempt from or subject to regular federal
income taxes cannot be predicted.
 
Interest on certain tax-exempt municipal securities issued after August 7, 1986
is a preference item for purposes of the alternative minimum tax ('AMT')
applicable to individuals and corporations. Under tax regulations to be issued,
the portion of any exempt-interest dividends paid by a regulated investment
company that is allocable to these obligations will be treated as a preference
item for purposes of the AMT. Corporations should, however, be aware that
interest on all municipal securities will be included in calculating among other
things 'adjusted current earnings' of corporations for AMT purposes. Such bonds
have
 
                                       33


<PAGE>

provided, and may continue to provide, somewhat higher yields than other
comparable municipal securities. While the Municipal Trust and Municipal Money
Fund may invest without limitation in securities subject to AMT, the AMT affects
only a small percentage of all tax paying investors.
 
Shareholders may be subject to state and local taxes on dividends from the
Municipal Trust Fund or Municipal Money Fund, including dividends which are
exempt from federal income taxes. In addition, for federal income tax purposes,
distributions of net short-term capital gains are taxable to shareholders of the
Municipal Trust Fund and Municipal Money Fund as ordinary income, and
distributions of net long-term capital gains are taxable to such shareholders as
long-term capital gains, regardless of the nature of the investments made by the
Fund.
 
Payment (either in cash or in portfolio securities) received by a shareholder
upon redemption of his shares, assuming the shares constitute capital assets in
his hands, will result in long-term or short-term capital gains (or losses)
depending upon the shareholder's holding period and basis in respect of shares
redeemed. Any loss realized by a shareholder on the sale of shares of a Fund
held for six months or less will be treated for federal income tax purposes as a
long-term capital loss to the extent of any distributions of long-term capital
gains received by the shareholder with respect to such shares. Any loss realized
on the sale of shares will be disallowed to the extent the shares disposed of
are replaced within a period of 61 days beginning 30 days before the disposition
of such shares. In such case, the basis of the shares acquired will be adjusted
to reflect the disallowed loss.
 
   
The foregoing discussion is a general summary of certain current federal income
tax laws regarding the Funds. The discussion does not purport to deal with all
of the federal income tax consequences applicable to the Funds or to all
categories of investors, some of whom may be subject to special rules. In
addition, this discussion does not describe any of the state or local tax
consequences that may be applicable to distributions paid by the Funds. Each
prospective and current shareholder should consult with his or her own
professional tax adviser regarding federal, state and local tax consequences of
ownership of shares of the Funds. Certain additional matters related to the tax
implications of investing in the Winthrop Funds are referenced in the Funds'
Statements of Additional Information.

RETIREMENT PLANS
 
   
Winthrop offers a range of qualified retirement plans including Traditional,
Educational and Roth IRAs, SEPs, SIMPLE plans and other pension and profit
sharing plans. Semper Trust Company serves as custodian under these prototype
retirement plans and charges an annual account maintenance fee of $15 per
participant, regardless of the number of Funds selected. Persons desiring

information concerning these plans should write or telephone Winthrop's Transfer
Agent at 1-800-225-8011. For a more detailed explanation of the retirement plans
offered by the Funds, see each Fund's Statement of Additional Information.
    
 
CAPITALIZATION
 
The Focus Funds were organized as a Massachusetts business trust under the laws
of Massachusetts on November 26, 1985. The Focus Funds have an unlimited number
of authorized shares of beneficial interest, par value $.01 per share, which
may, without shareholder approval, be divided into an unlimited number of series
and an unlimited number of classes. Such shares are currently divided into five
series.
 
The Opportunity Funds were organized as a Delaware business trust under the laws
of Delaware on May 31, 1995. The Opportunity Funds have an unlimited number of
authorized shares of beneficial interest, par value $.001 per share, which may,
without shareholder approval, be divided into an unlimited number of series and
an unlimited number of classes. Such shares are currently divided into four
series, two series in each of the International Funds and Money Funds.
 
Shares of the Focus Funds and the International Funds are divided into Class A
and Class B shares. Winthrop currently offers only one class of shares for the
Money Funds. Shares held in each Fund are normally entitled to one vote (with
proportional voting for fractional shares) for all purposes. Generally, shares
of the International Funds and Money Funds vote as a single series on matters
that affect all Funds within the Opportunity Funds in substantially the same
manner and shares of the Focus Funds vote as a single series on matters that
affect all Funds within the Focus Funds in substantially the same manner. As to
matters affecting each Focus Fund, International Fund or Money Fund separately,
such as approval of the investment advisory agreement, shares of each Focus
Fund, International Fund or Money Fund would vote as separate series.
 
With respect to the Focus Funds and International Funds, each Class is identical
in all respects except that (i) each Class bears different distribution service
fees, (ii) each Class has exclusive voting rights with respect to its 12b-1
Plan, (iii) each Class has different exchange privileges, and (iv) only Class B
shares have a conversion feature.
 
The Funds will not have annual meetings of shareholders so long as at least
two-thirds of their Trustees then in office have been elected by their
shareholders. Section 16(c) of the 1940 Act provides certain rights to
shareholders which Winthrop will honor regarding the calling of meetings of
shareholders and other communications with shareholders. Trustees
 
                                       34

<PAGE>

also may call meetings of shareholders from time to time as the Trustees deem
necessary or desirable.
 
Shares of a Fund are freely transferable, are entitled to dividends as
determined by the Trustees and, in liquidation of Winthrop, are entitled to

receive the net assets of that Fund. Since Class B shares of the Focus Funds and
International Funds are subject to greater distribution services fees than Class
A shares of such Funds, the liquidation proceeds to shareholders of Class B
shares are likely to be less than proceeds to Class A shareholders. Shareholders
have no preemptive rights.
 
PORTFOLIO TRANSACTIONS
 
Consistent with the Rules of Fair Practice of the National Association of
Securities Dealers, Inc. and subject to seeking best execution, Winthrop may
consider sales of its shares as a factor in the selection of brokers and dealers
to execute portfolio transactions for Winthrop.
 
DISTRIBUTOR
 
Donaldson, Lufkin & Jenrette Securities Corporation, an affiliate of the
Advisers, serves as Winthrop's Distributor.
 
CUSTODIAN, DIVIDEND DISBURSING AGENT AND TRANSFER AGENT
 
Citibank, N.A. acts as Custodian for the securities and cash of Winthrop, but
plays no part in deciding on the purchase or sale of portfolio securities. FPS
Services, Inc. acts as dividend disbursing agent, registrar and transfer agent
of Winthrop.
 
HOW WINTHROP CALCULATES PERFORMANCE
 
From time to time Winthrop may advertise its total return (including 'average
annual' total return and 'aggregate' total return) and yield in advertisements
or sales literature. Total return and yield are calculated separately for Class
A and Class B shares. These figures are based on historical earnings and are not
intended to indicate future performance. The 'total return' shows how much an
investment in a Fund would have increased (decreased) over a specified period of
time (i.e., one, five or ten years or since inception of that Fund) assuming
that all distributions and dividends by the Fund were reinvested on the
reinvestment dates during the period and less all recurring fees. The
'aggregate' total return reflects actual performance over a stated period of
time. 'Average annual' total return is a hypothetical rate of return that, if
achieved annually, would have produced the same aggregate total return if
performance had been constant over the entire period. 'Average annual' total
return smoothes out variations in performance. Winthrop's advertisements of
total return and average annual total return may not reflect any applicable
initial or contingent deferred sales charge, but such charges will be disclosed.
Neither 'average annual' total return nor 'aggregate' total return takes into
account any federal or state income taxes which may be payable upon redemption.
The '30-day yield' refers to the income generated by an investment in a Fund
over a one-month or 30-day period. This income is then 'annualized,' that is,
the amount of income generated by the investment during that 30-day period is
assumed to be generated each 30-day period for twelve periods and is shown as a
percentage of the investment. The income earned on the investment is also
assumed to be reinvested at the end of the sixth 30-day period. Winthrop may
also include comparative performance information in advertising or marketing
Winthrop's shares. Such performance information may include data from Lipper
Analytical Services, Inc., Morningstar Publications, Inc., other industry

publications, business periodicals, and market indices. Further performance
information is contained in Winthrop's annual reports to shareholders, which may
be obtained without charge.
 
INFORMATION FOR SHAREHOLDERS
 
Any shareholder inquiry regarding Winthrop or the status of the shareholder's
account can be made to Winthrop or to FPS Services, Inc. by telephone or by mail
at the telephone number or the addresses listed on the back cover of this
Prospectus.
 
Following any purchase or redemption, a shareholder will receive a statement
confirming the transaction. Annual audited and semi-annual unaudited financial
statements, which include a list of investments held by Winthrop, will be sent
to shareholders.
 
   
YEAR 2000 COMPLIANCE
    
 
   
As the year 2000 approaches, an issue has emerged regarding how existing
application software programs and operating systems can distinguish between the
year 2000 and the year 1900. Failure to adequately address this issue could have
potentially serious repercussions to the Funds and their respective shareholders
as the Funds are dependent on the smooth functioning of the computer software
and operating systems of their respective Advisers, Distributor, Custodian and
Transfer Agent. The Advisers are in the process of working with the Funds'
service providers to prepare for the year 2000 and expect that, together with
such service providers, they will be year 2000 compliant on a timely basis. As
of the date of this Prospectus, the Funds do not expect that they will incur
significant operating expenses or be required to incur material costs to be year
2000 compliant.

to some investors, has been filed with the Securities and Exchange Commission

* Management Fees with respect to the Money Funds are reduced to .35% on net
  assets in excess of $1 billion.
 
** The Money Funds have entered into a Distribution Agreement and a Rule 12b-1
   Plan pursuant to which each Money Fund pays a distribution fee each month
   at an annual rate of up to .25 of 1% of the average daily net assets of
   each Money Fund. Amounts paid under the Distribution Agreement are used in
   their entirety to reimburse the Money Funds' distributor for actual
   expenses incurred. Long-term shareholders may, over time, pay more in 12b-1
   Fees than the economic equivalent of the maximum front-end sales charges
   permitted by the National Association of Securities Dealers, Inc. See
   "Expenses of the Money Funds -- Distribution Agreement."

 
(1) The maximum allowable amount payable for distributing shares is .40 of 1%
    of the average daily net assets of each Money Fund. The Board of Trustees
    has currently limited the amount payable to .25 of 1% of the average daily
    net assets of each Money Fund.
 
(2) Commencing at the inception of each Money Fund and through April 30, 1998,
    the Adviser has agreed to reduce its management fees and the Adviser or
    its affiliates have agreed to reimburse operating expenses by the amount
    that Total Fund Operating Expenses exceed .90% of the average daily net
    assets of each Money Fund. During the period from the Money Funds'
    inception on February 24, 1997 through October 31, 1997, Total Fund
    Operating Expenses and Other Expenses, as so adjusted reflect a voluntary
    reduction amounting to .40% for the Municipal Money Fund and .45% for the
    U.S. Government Money Fund. Absent such reimbursement, Other Expenses and
    Total Fund Operating Expenses would have been .65% and 1.30%,
    respectively, for the Municipal Money Fund and .70% and 1.35%,
    respectively, for the U.S. Government Money Fund. After April 30, 1998,
    the Adviser or its affiliates may, in their discretion, determine to
    discontinue this practice with respect to either Money Fund.

    "Other Expenses" includes fees paid to the Money Funds' independent
auditor, legal counsel and Trustees as well as expenses associated with
registration fees, reports to shareholders and other miscellaneous expenses.
Such fees are not based on a percentage of each Money Fund's average net
assets, but a fixed dollar cost. The percentages for other fixed cost
expenses are the maximum allowed to be charged to the Money Funds as total

operating expenses are capped at the percentages stated above.

                                 INTRODUCTION
 
    Winthrop Opportunity Funds is a Delaware business trust whose shares are
offered in four separate portfolios: the Winthrop Municipal Money Fund (the
"Municipal Fund") and the Winthrop U.S. Government Money Fund (the "Government
Fund" and together with the Municipal Fund, the "Money Funds"), and the
Winthrop Developing Markets Fund and the Winthrop International Equity Fund
(the "International Funds"), which are offered in a separate prospectus.
Because Winthrop Opportunity Funds offers multiple funds, it is known as a
"series fund." Winthrop Opportunity Funds may in the future establish
additional series with different investment objectives and policies and offer
additional classes of shares.
 
    Each portfolio of the Winthrop Opportunity Funds is a separate pool of
assets constituting, in effect, a separate fund with its own investment
objective and policies. (See "Investment Objectives, Policies and Risk
Considerations.") A shareholder may utilize the Money Funds' exchange
privilege to transfer such shareholder's assets to the International Funds or
for shares of the Winthrop Growth Fund, Winthrop Fixed Income Fund, Winthrop
Small Company Value Fund, Winthrop Growth and Income Fund or the Winthrop
Municipal Trust Fund (collectively, the "Focus Funds") in accordance with the
shareholder's changing perceptions of the relative investment potential of
each investment alternative. A shareholder will pay a higher 12b-1 Fee when
exchanging shares of the Money Funds (.25 of 1% annually) for Class A shares
of the Focus Funds (.30 of 1% annually) or Class B shares of the International
Funds or Focus Funds (1% annually). (See "Purchases, Redemptions and
Shareholder Services.") In addition, a shareholder may be subject to sales
charges upon exchanging shares of the Money Funds for shares of the
International Funds or Focus Funds. (See "Additional Shareholder
Services -- Exchange Privilege.") Shareholders of the Money Funds are entitled
to their pro rata share of any dividends and distributions arising from that
Money Fund's assets (See "Daily Dividends, Distributions and Taxes.") Upon
redeeming shares of a Money Fund, the shareholder will receive the
next-determined net asset value of that Fund represented by the redeemed
shares which is expected to remain constant at $1.00 per share. (See
"Purchases, Redemptions and Shareholder Services.")
 
           INVESTMENT OBJECTIVES, POLICIES AND RISK CONSIDERATIONS
 
    The investment objectives and policies of each Money Fund are set forth
below. There can be, of course, no assurance that either Money Fund will
achieve its respective investment objective.
 
    The investment objectives of each Money Fund are fundamental policies of
that Money Fund and may not be changed without the approval of that Money
Fund's shareholders. Except as set forth in "Investment Policies and

Restrictions" in the Statement of Additional Information, or as otherwise
indicated below, the investment policies of each Money Fund are not
fundamental policies and may be changed by the Board of Trustees without a
shareholder vote. A more detailed explanation of the Money Funds' policies and
the securities and instruments they may buy or use is contained in the Money
Funds' Statement of Additional Information, which is available upon request.
 
The Winthrop Municipal Money Fund
 
    The Municipal Fund's investment objectives are to seek maximum current
income, consistent with liquidity and safety of principal, that is exempt from
income taxation to the extent described below. As a matter of fundamental
policy, the Municipal Fund pursues its objectives by investing in high quality
municipal securities having remaining maturities of one year or less, which
maturities may extend to 397 days, and at least 80% of the Municipal Fund's
total assets will be invested in such securities (as opposed to the taxable
investments described below). However, the Municipal Fund reserves the right
to lower the percentage to 65% if economic or political conditions
 
                                      4
<PAGE>
 
 
warrant. To increase the Municipal Fund's ability to reach its investment
objectives, the dollar weighted average maturity of its portfolio securities
is always 90 days or less. In general, securities with longer maturities are
more vulnerable to price changes, although they may provide higher yields. It
is possible that a major change in interest rates or a default on the
Municipal Fund's investments could cause their share prices to change. There
can be no assurance, as is true with all investment companies, that the
Municipal Fund's investment objectives will be achieved.
 
    Normally, substantially all the Municipal Fund's income will be tax-exempt
as described below. Such income may be subject to state or local income taxes.
 
    The municipal securities in which the Municipal Fund invests include
municipal notes and short-term municipal bonds. Municipal notes are generally
used to provide for short-term capital needs and generally have maturities of
one year or less. Examples include tax anticipation and revenue anticipation
notes, which are generally issued in anticipation of various seasonal
revenues, bond anticipation notes, and tax-exempt commercial paper. Short-term
municipal bonds may include general obligation bonds, which are secured by the
issuer's pledge of its faith, credit and taxing power for payment of principal
and interest, and revenue bonds, which are generally paid from the revenues of
a particular facility or a specific excise or other source.
 
    The Municipal Fund may invest in variable rate obligations whose interest
rates are adjusted either at predesignated periodic intervals or whenever
there is a change in the market rate to which the security's interest rate is
tied. Such adjustments minimize changes in the market value of the obligation
and, accordingly, enhance the ability of the Municipal Fund to maintain a
stable net asset value. Variable rate securities purchased may include
participation interests in industrial development bonds which may be backed by
letters of credit from banking or other financial institutions. The letters of

credit of any single of such institutions in respect of all variable rate
obligations will not cover more than the allowable percentage of the Municipal
Fund's total assets in accordance with Rule 2a-7 of the Investment Company Act
of 1940 (the "1940 Act").
 
    The Municipal Fund may invest without limitation in tax-exempt municipal
securities subject to the alternative minimum tax (the "AMT"). Under current
Federal income tax law, (1) interest on tax-exempt municipal securities issued
after August 7, 1986 which are "specified private activity bonds," and the
proportionate share of any exempt-interest dividends paid by a regulated
investment company which receives interest from such specified private
activity bonds, will be treated as an item of tax preference for purposes of
the AMT imposed on individuals and corporations, though for regular Federal
income tax purposes such interest will remain fully tax-exempt, and (2)
interest on all tax-exempt obligations will be included in "adjusted current
earnings" of corporations for AMT purposes. Such bonds have provided, and may
continue to provide, somewhat higher yields than other comparable municipal
securities. While the Municipal Fund may invest without limitation in
securities subject to AMT, the AMT affects only a small percentage of all tax
paying investors. (See "Daily Dividends, Other Distributions and Taxes.")
 
    All of the Municipal Fund's municipal securities at the time of purchase
are rated within the two highest quality ratings of Moody's Investors Service,
Inc. (Aaa and Aa, MIG 1 and MIG 2 or VMIG1 and VMIG2) or Standard & Poor's
Corporation (AAA and AA or SP-1 and SP-2), or judged by the Adviser (as
defined under "Management") to be of comparable quality.
 
    Pursuant to the 1940 Act, a fund generally may invest up to 10% of its
total assets in the aggregate in shares of other investment companies and up
to 5% of its total assets in any one investment company as long as each
investment does not represent more than 3% of the outstanding voting stock of
the acquired investment company at the time of investment. Investment in other
investment companies may involve the payment of substantial premiums above the
value of such investment companies' portfolio securities, and is subject to
limitations under the 1940 Act and market availability. The Municipal Fund may
invest in such investment companies if, in the judgment of the Adviser, the
potential benefits of such investment justifies the payment of any applicable
premium or sales charge. As a shareholder in an investment company, the
Municipal Fund would bear its ratable share of that investment company's
expenses, including its advisory
 
                                      5
 
<PAGE>
 
and administrative fees. At the same time the Municipal Fund would continue to
pay its own management fees and other expenses.
 
    To maintain portfolio diversification and reduce investment risk, the
Municipal Fund may not: (1) borrow money except from banks on a temporary
basis or via entering into reverse repurchase agreements to be used
exclusively to facilitate the orderly maturation and sale of portfolio
securities during any periods of abnormally heavy redemption requests, if they
should occur; such borrowings may not be used to purchase investments; or (2)

pledge, hypothecate or in any manner transfer, as security for indebtedness,
its assets except to secure such borrowings.
 
    The Municipal Fund may also invest in stand-by commitments,
delayed-delivery and when-issued securities, which may involve certain
expenses and risks. The Municipal Fund's custodian will maintain a segregated
account containing liquid securities having value equal to, or greater than,
such securities. The price of such securities, which is generally expressed in
yield terms, is fixed at the time the commitment to purchase is made, but
delivery and payment for such securities takes place at a later time. Normally
the settlement date occurs from within ten days to one month after the
purchase of the issue. The value of such securities may fluctuate prior to
their settlement, thereby creating an unrealized gain or loss to the Municipal
Fund. Such securities are examples of what the Securities and Exchange
Commission (the "SEC") considers "illiquid securities" because their
settlement date occurs more than seven days after their purchase. The SEC
limits money market funds to hold only up to 10% of their net assets in
illiquid securities.
 
    The Municipal Fund may also invest in municipal leases, which are leases
or installment purchases used by state and local governments as a means to
acquire property, equipment or facilities without involving debt issuance
limitations. It is possible that more than 5% of the Municipal Fund's net
assets will be invested in municipal leases which have been determined to be
liquid securities by the Municipal Fund's adviser.
 
    The taxable investments in which the Municipal Fund may invest include
obligations of the U.S. Government and its agencies, high quality certificates
of deposit and bankers' acceptances, prime commercial paper, and repurchase
agreements.
 
    To seek to reduce investment risk, the Municipal Fund may not invest in
the securities of any one issuer, except the U.S. Government, in excess of the
percentage of the Municipal Fund's total assets allowed under Rule 2a-7 of the
Investment Company Act of 1940.
 
    The Municipal Fund earns income at current money market rates and its
yield will vary from day to day and generally reflects current short-term
interest rates and other market conditions. It is important to note that
neither the Municipal Fund nor its yields are insured or guaranteed by the
U.S. Government.
 
The Winthrop U.S. Government Money Fund
 
    The Government Fund's investment objectives are to seek maximum current
income, consistent with liquidity and safety of principal. As a matter of
fundamental policy, the Government Fund pursues its objectives by maintaining
a portfolio of high quality money market securities, including the types
described in the succeeding paragraph, which at the time of investment
generally have remaining maturities of one year or less, although maturities
may extend to 397 days. The dollar weighted average maturity of the Government
Fund's portfolio securities will vary, but will always be 90 days or less. In
general, securities with longer maturities are more vulnerable to price
changes, although they may provide higher yields. It is possible that a major

change in interest rates or a default on the Government Fund's investments
could cause their share prices to change. There can be no assurance, as is
true with all investment companies, that the Government Fund's objectives will
be achieved.
 
    The securities in which the Government Fund invests are: (1) marketable
obligations of, or guaranteed by, the United States Government, its agencies
or instrumentalities (collectively, the "U.S. Government"), including issues
of the United States Treasury, such as bills, certificates of indebtedness,
notes and bonds, and issues of agencies and instrumentalities established
under the authority of an act of Congress, including variable rate obligations
such as floating rate notes; and (2) repurchase agreements that are
collateralized in full each day by eligible mortgage related securities or the
types of
 
                                      6
<PAGE>
 
 
securities listed above. These agreements are entered into with "primary
dealers" (as designated by the Federal Reserve Bank of New York) in U.S.
Government securities and would create a loss to the Government Fund if, in
the event of a dealer default, the proceeds from the sale of the collateral
were less than the repurchase price. In addition, if the seller of repurchase
agreements becomes insolvent, the Government Fund's right to dispose of the
securities might be restricted.
 
    The Government Fund may commit up to 10% of its net assets to the purchase
of illiquid securities, which includes when-issued U.S. Government securities,
whose value may fluctuate prior to their settlement, thereby creating an
unrealized gain or loss to the Government Fund.
 
    The Government Fund earns income at current money market rates and its
yield will vary from day to day and generally reflects current short-term
interest rates and other market conditions. It is important to note that
neither the Government Fund nor its yield is insured or guaranteed by the U.S.
Government.
    To maintain portfolio diversification and reduce investment risk, the
Government Fund may not: (1) borrow money except from banks on a temporary
basis or via entering into reverse repurchase agreements to be used
exclusively to facilitate the orderly maturation and sale of portfolio
securities during any periods of abnormally heavy redemption requests, if they
should occur; such borrowings may not be used to purchase investments; or (2)
pledge, hypothecate or in any manner transfer, as security for indebtedness,
its assets except to secure such borrowings.
 
    In addition to the above referenced securities, the Money Funds reserve
the right as a defensive measure to hold temporarily other types of securities
which are permitted by Rule 2a-7 of the Investment Company Act of 1940. See
"Investment Policies and Restrictions" in the Statement of Additional
Information for a more complete description of the Money Funds' objectives,

                                  MANAGEMENT
 
    The Money Funds' Board of Trustees (who, with its officers, are described
in the Statement of Additional Information) has overall responsibility for the
management of the Funds.
 
    DLJ Investment Management Corp. (the "Adviser"), a Delaware corporation
with principal offices at 277 Park Avenue, New York, New York 10172, has been
retained under an investment advisory agreement to provide investment advice
and to supervise the management and investment programs of the Money Funds,
subject to the general supervision and control of the Trustees of the Funds.
 
    The Adviser is a wholly-owned subsidiary of Donaldson, Lufkin & Jenrette
Securities Corporation, which is a member of the New York Stock Exchange and a
wholly-owned subsidiary of Donaldson, Lufkin & Jenrette, Inc. ("DLJ"), a major
international supplier of financial services. DLJ is an independently
operated, indirect subsidiary of The Equitable Companies Incorporated, a
holding company controlled by AXA-UAP ("AXA"), a member of a large French
insurance group. AXA is indirectly controlled by a group of four French mutual
insurance companies. The Adviser was formed in November, 1995 for the initial
purpose of acting as investment adviser to a select group of individual and
institutional investors. The Adviser has hired personnel from both within and
outside of DLJ who have experience in the investment company industry,
specifically the operation and management of money market funds.
 
    Under its Advisory Agreement with the Money Funds, the Adviser or its
affiliates (i) provide investment advisory services and order placement
facilities for each of the Money Funds and pays all compensation of Trustees
of the Money Funds who are affiliated persons of the Adviser and (ii) furnish
the Money Funds' management supervision and assistance and office facilities
in addition to administrative and other nonadvisory services for which it may
be reimbursed. The Money Funds pay a fee of .40% of the average
 
                                      7
<PAGE>
 
 
daily net assets of each Money Fund to the Adviser which is reduced to .35% of
each Money Fund's average daily net assets in excess of $1 billion. The
advisory fees to be paid by the Money Funds are similar to those paid by other
money market mutual funds.
 
    For the period from the inception of the Money Funds on February 24, 1997
through October 31, 1997, pursuant to the investment advisory agreement, the
Money Funds paid the Adviser, advisory fees equivalent to .40% (annualized) of
the average daily net assets of each Fund. The total operating expenses of the
Municipal Fund and the Government Fund for such period were $260,693 and
$230,350, respectively. Commencing at the inception of the Money Funds through
April 30, 1998, the Adviser has agreed to reduce its management fees and the
Adviser or its affiliates have agreed to reimburse operating expenses by the
amount that total operating expenses exceed .90% of the average daily net
assets of each Money Fund. After April 30, 1998, the Adviser or its affiliates
may, in their discretion, determine to discontinue this practice with respect
to either Money Fund.

 
                         EXPENSES OF THE MONEY FUNDS
 
General
 
    In addition to the payments to the Adviser under the investment advisory
agreement described above, the Money Funds pay the other expenses incurred in
the Money Funds' organization and operations, including the costs of printing
prospectuses and other reports to existing shareholders; all expenses and fees
related to registration and filing with the SEC and with state regulatory
authorities; custody, transfer and dividend disbursing expenses; legal and
auditing costs; clerical, accounting, and other office costs; fees and
expenses of Trustees who are not affiliated with the Adviser; costs of
maintenance of existence; and interest charges, taxes, brokerage fees, and
commissions.
 
    The investment advisory agreement provides that the Adviser will reimburse
the Money Funds up to the amount of its advisory fee for the expenses of any
Money Fund (exclusive of interest, taxes, brokerage, expenditures pursuant to
the distribution services agreement described below, and extraordinary
expenses, all to the extent permitted by applicable state law and regulations)
which in any year exceed the limits prescribed by any state in which shares of
such Money Fund are qualified for sale.
 
Distribution Agreement
 
    Rule 12b-1 adopted by the SEC under the 1940 Act permits an investment
company directly or indirectly to pay expenses associated with the
distribution of its shares. Under SEC regulations, some of the payments
described below to be made by the Money Funds could be deemed to be
distribution expenses within the meaning of such rule. Thus, pursuant to Rule
12b-1, the Money Funds' Trustees, including a majority of its disinterested
Trustees, have adopted separate 12b-1 Plans for the expenses to be incurred in
distributing each Money Fund's shares (the "Rule 12b-1 Plans") and the Money
Funds have entered into a Distribution Agreement (the "Agreement") with
Donaldson, Lufkin & Jenrette Securities Corporation, the Funds' distributor
(the "Distributor"). The Distributor may enter into service agreements with
other entities. The Distributor is located at 277 Park Avenue, New York, New
York 10172.
 
    With respect to each Money Fund, the maximum amount payable by the Money
Funds under the Rule 12b-1 Plans for distributing shares is .40 of 1% of the
average daily net assets of each Fund during the year. The current amount
payable by the Money Funds under the Rule 12b-1 Plans to the Distributor is
 .25 of 1% of the average daily net assets of each Fund during the year.
Pursuant to the Agreements, the Trustees can raise the distribution fees up to
the maximum amount by a majority vote if the Trustees, in their opinion, feel
that the raise is in the best interest of the Money Funds and their
shareholders. The Agreement but not the Rule 12b-1 Plans terminate in the
event of assignment of the Agreement.
 
    An initial concession or ongoing maintenance fee may be paid to
broker-dealers on sales of both Money
 

                                      8
<PAGE>
 
 
Funds' shares. Pursuant to the Rule 12b-1 Plans, the Distributor is then
reimbursed for such payments with amounts paid from the assets of such Money
Fund. The payments to the broker-dealer, although a Money Fund expense which
is paid by all shareholders, will only directly benefit investors who purchase
their shares through a broker-dealer rather than directly from the Money
Funds. Broker-dealers who sell shares of the Money Funds may provide services
to their customers that are not available to investors who purchase their
shares directly from the Money Funds. The payments to the broker-dealers will
continue to be paid for as long as the related assets remain in the Money
Funds.
 
    Amounts paid under the Rule 12b-1 Plans and the Agreement are used in
their entirety to reimburse the Distributor for actual expenses incurred to
(i) promote the sale of shares of each Money Fund by, for example, paying for
the preparation, printing and distribution of prospectuses, sales brochures
and other promotional materials sent to prospective shareholders, by directly
or indirectly purchasing radio, television, newspaper and other advertising or
by compensating the Distributor's employees or employees of the Distributor's
affiliates for their distribution assistance, (ii) make payments to the
Distributor to compensate broker-dealers or other persons for providing
distribution assistance and (iii) make payments to compensate financial
intermediaries for providing administrative and accounting services with
respect to the Money Funds' shareholders. In addition to the concession or
maintenance fee which may be paid to dealers or agents, the Distributor may
from time to time pay additional compensation to dealers or agents in
connection with the sale of shares. Such additional amounts may be utilized,
in whole or in part, in some cases together with other revenues of such
dealers or agents, to provide additional compensation to registered
representatives of such dealers or agents who sell shares of a Money Fund. On
some occasions, such compensation will be conditioned on the sale of a
specified minimum dollar amount of the shares of the Money Funds during a
specific period of time. Such incentives may take the form of payment for
meals, entertainment, or attendance at educational seminars and associated
expenses such as travel and lodging. Such dealer or agent may elect to receive
cash incentives of equivalent amounts in lieu of such payments. The Rule 12b-1
Plans permit payments to be made in subsequent years for expenses incurred in
prior years if the Money Funds' Trustees specifically authorize such payment.
For the period from the inception of the Money Funds on February 24, 1997
through October 31, 1997, distribution costs incurred for the Municipal Fund
and the Government Fund were $50,107 and $42,735, respectively. For the year
ended October 31, 1997, the amounts eligible for payment in subsequent years
were $50,107 and $42,735 for the Municipal Money Fund and the U.S. Government
Money Fund, respectively, which represents 0.13% and 0.12% of the Funds'
October 31, 1997 net assets, respectively.
 
               PURCHASES, REDEMPTIONS AND SHAREHOLDER SERVICES
 
Purchases
 
    Shares of each of the Money Funds will be offered on a continuous basis

directly by the Money Funds and by the Distributor, acting as agent for the
Money Funds, at the respective net asset value per share determined as of the
close of the regular trading session of the New York Stock Exchange (the
"NYSE"), currently 4:00 p.m., New York City time, following receipt of a
purchase order in proper form. (See "Net Asset Value.") The investor should
send a completed Share Purchase Application (found in this Prospectus) and
enclose a check in the amount of the initial investment to the Transfer Agent,
FPS Services, Inc., P.O. Box 61503, King of Prussia, PA 19406-0903, Attn:
Winthrop Mutual Funds. (For overnight courier deliveries, replace P.O. Box
61503 on the address label with 3200 Horizon Drive.) The account will be
established once the application and check are received in good order. Checks
should be made payable to "Winthrop Mutual Funds." Checks made payable to the
shareholder or another third party (third party checks) will not be accepted
by the Money Funds or the Transfer Agent for
 
                                      9

investment. To open a new account by wire, first call Winthrop Opportunity
Funds at 1-800-225-8011 (option #2) to obtain an account number. A
representative will instruct you to send a completed, signed application to
the Transfer Agent. Accounts cannot be opened without a completed, signed
application and a fund account number. Contact your bank to arrange a wire
transfer to:
 
    UMB Bank, n.a.
    ABA #10-10-00695
    For: FPS Services, Inc.
    A/C #98-7037-0719
    Attn: Winthrop Mutual Funds
 
    Your wire instructions must also include:
 
     --   the name of the Fund in which the money is to be invested,
     --   your account number at the Fund, and
     --   the name(s) of the account holder(s).
 
Investors who purchase shares of the Money Funds through a wire transfer will
be eligible to receive the daily dividend declared on the date of purchase if
the Transfer Agent is notified of such purchase by 12:00 Noon and wired funds
are received by the Transfer Agent by 4:00 p.m. (See "Daily Dividends,
Distributions and Taxes.")
 
    Investors may also open accounts via their securities dealer. In addition,
securities dealers may offer an automatic sweep for the shares of the Money
Funds in the operation of cash accounts for its customers. Shares of the Money
Funds purchased through an automatic sweep by 1:00 p.m. are eligible to
receive that day's daily dividend. Contact your securities dealer to determine
if a sweep is available and what the sweep parameters are.
 
    The minimum initial and subsequent investment in each Money Fund is $250
and $25, respectively. (For example, an investor wishing to make an initial
investment in shares of both Money Funds would be required to invest at least

$250 in each Money Fund.) Full and fractional shares will be credited to an
investor's account in the amount of the investment. Share certificates will
not be issued for full or fractional shares of the Money Funds. Each Money
Fund reserves the right to reject any initial or subsequent investment in its
sole discretion. Shareholder accounts established on behalf of the following
types of plans will be exempt from the Money Fund's minimum initial investment
and minimum subsequent investment requirements: (i) retirement plans qualified
under section 401(k) of the Code; (ii) plans described in section 403(b) of
the Code; (iii) deferred compensation plans described in section 457 of the
Code; (iv) simplified employee pension (SEP) plans; and (v) savings incentive
match plans for employees (SIMPLE).
 
    Existing shareholders wishing to purchase additional shares of a Money
Fund may use an investment stub found at the bottom of the Money Fund's
Shareholder Statement form or, if one is not available, they may send a check
payable to such Money Fund (with Fund Account information referenced) directly
to the Transfer Agent, FPS Services, Inc., P.O. Box 61503, King of Prussia, PA
19406-0903, Attn: Winthrop Mutual Funds. (For overnight courier deliveries,
replace P.O. Box 61503 on the address label with 3200 Horizon Drive.) Existing
shareholders may also purchase additional shares via wire by contacting and
providing the Fund Account information to the Transfer Agent and following the
wire instructions above.
 
    Further information and assistance is available by contacting the Money
Funds at the address or telephone number listed on the cover page of this
Prospectus.
 
Redemptions
 
    Shares of the Money Funds may be redeemed at a redemption price equal to
the net asset value per share, as next computed as of the close of the regular
trading session of the NYSE, currently 4:00 p.m., New York City time,
following the receipt in proper form by the Money Fund of shares tendered for
redemption. (See "Net Asset Value.")
 
    The value of a shareholder's shares on redemption though expected to
remain at $1.00 per share may be more or less than the cost of such shares to
the shareholder, depending upon the value of a Money Fund's portfolio
securities at the time of such redemption or repurchase. Shares do not earn
dividends on the day a redemption is effected. (See "Daily Dividends,
Distributions and Taxes" for a discussion of the tax consequences of a
redemption.)
 
                                      10
<PAGE>
 
 
    To redeem shares, the registered owner or owners should forward a letter
to the Money Funds containing a request for redemption of such shares at the
next determined net asset value per share. Alternatively, the shareholder may
elect the right to redeem shares by telephone. If you wish to have Federal
funds wired the same day as your telephone redemption request, make sure that
your request will be received by the Money Funds prior to 12:00 Noon. (See
"Additional Shareholder Services -- Telephone Redemption and Exchange

Privilege.") If a shareholder's securities dealer offers an automatic sweep
service, the sweep will automatically transfer from the Money Fund account
sufficient cash to cover any debit balance that may occur in your cash
account. Shares of the Money Funds redeemed prior to 1:00 p.m. through an
automatic sweep service will be eligible for same day federal funds wiring.
 
    If the total value of the shares being redeemed exceeds $50,000 or a
redemption request directs proceeds to a party other than the registered
account owner(s), the signature or signatures on the letter or the endorsement
must be guaranteed by an "eligible guarantor institution" as defined in Rule
17Ad-15 under the Securities Exchange Act of 1934. Eligible guarantor
institutions include banks, brokers, dealers, credit unions, national
securities exchanges, registered securities associations, clearing agencies
and savings associations. A broker-dealer guaranteeing signatures must be a
member of a clearing corporation or maintain net capital of at least $100,000.
Credit unions must be authorized to issue signature guarantees. Signature
guarantees will be accepted from any eligible guarantor institution which
participates in a signature guarantee program. Additional documents may be
required for redemption of corporate, partnership or fiduciary accounts.
 
    The requirement for a guaranteed signature is for the protection of the
shareholder in that it is intended to prevent an unauthorized person from
redeeming shares and obtaining the redemption proceeds.
 
    A Money Fund may request in writing that a shareholder whose account in a
Money Fund has an aggregate balance less than $250 increase his account to at
least that amount within 60 days. If the shareholder fails to do so, such
Money Fund reserves the right to close such account and send the proceeds to
the shareholder. A Money Fund will not redeem involuntarily any shareholder
account based solely on the market movement of such Money Fund's shares.
 
    The right of redemption may not be suspended or the date of payment upon
redemption postponed for more than seven days after shares are tendered in
proper form, except for any period during which the NYSE is closed (other than
customary weekend and holiday closings) or during which trading on the
exchange is deemed to be restricted under rules of the SEC, or for any period
during which an emergency (as determined by the SEC) exists as a result of
which disposal by a Money Fund of its portfolio securities is not reasonably
practicable, or as a result of which it is not reasonably practicable for a
Money Fund to determine the value of its net assets, or for such other period
as the SEC may by order permit for the protection of shareholders. Generally,
redemption will be made by payment in cash or by check. For information
concerning circumstances in which redemptions may be effected through the
delivery of in kind portfolio securities, see the Statement of Additional
Information.
 
Additional Shareholder Services
 
    Exchange Privilege. Shares of each Money Fund can be exchanged for shares
of the other Money Fund. Shareholders whose initial investment was directly
into a Money Fund may exchange such shares into either class of the
International Funds or the Focus Funds. Shares of each Money Fund established
pursuant to Winthrop's exchange privilege will be eligible for exchange into
the International Funds or Focus Funds provided that the exchange is directed

into the same class of shares upon which the initial investment was made.
Exchanges may be made by mail or telephone (see "Additional Shareholder
Services -- Telephone Redemption and Exchange Privilege"). Unless otherwise
indicated on the initial Share Purchase Application or by written notice to
the Money Funds or its Transfer Agent, shareholders whose initial investment
was invested directly into a Money Fund will, upon an exchange request,
automatically be exchanged into Class A shares of the requested International
Funds or Focus Funds. The exchange privilege for the Interna-
 
                                      11
<PAGE>
 
 
tional Funds and the Focus Funds is available only in states in which shares
of the relevant International Fund or Focus Fund may be legally sold. A
prospectus for the International Funds and the Focus Funds may be obtained
from the address or telephone number listed on the cover page of this
Prospectus. An exchange is effected on the basis of each Money Fund's relative
net asset value per share next computed following receipt of an order for such
exchange from the shareholder.
 
    The Money Funds impose no separate charge for exchanges. A shareholder
will not be assessed any contingent deferred sales charge at the time of an
exchange between any of the Money Funds, International Funds or Focus Funds.
However, shares of the Money Funds established through an exchange of shares
subject to a contingent deferred sales charge will be charged at the time of
redemption. The period of time during which a shareholder owns shares in any
of the Money Funds, International Funds or Focus Funds will be used to
determine the applicable contingent deferred sales charge. A shareholder will
pay a higher 12b-1 Fee when exchanging shares of the Money Funds (.25 of 1%
annually) for Class A shares of the Focus Funds (.30 of 1% annually) or Class
B shares of the International Funds or Focus Funds (1% annually).
 
    There is no sales load associated with the purchase and sale of shares of
the Money Funds. However, a shareholder may be subject to sales charges upon
exchanging shares of the Money Funds for Class A shares of the International
Funds and Focus Funds. Currently, Class A shares of the International Funds
and Focus Funds have initial sales loads of 5.75% and 4.75%, respectively,
while Class B shares of the International Funds and Focus Funds are subject to
a contingent deferred sales charge which declines from 4% during the first
year of investment to zero after four years. A prospectus describing the sales
charges associated with either the International Funds or Focus Funds can be
obtained from the address or phone number at the beginning of this Prospectus.
 
    The exchange privilege is intended to provide shareholders with a
convenient way to switch their investments when their objectives or perceived
market conditions suggest a change. The exchange privilege is not meant to
afford shareholders an investment vehicle to play short term swings in the
stock market by engaging in frequent transactions in and out of the Money
Funds, International Funds and Focus Funds. Shareholders who engage in such
frequent transactions may be prohibited from or restricted in placing future
exchange orders.
 
    Shareholders should be aware that an exchange is treated for federal

income tax purposes as a sale and purchase of shares which may result in
realization of a gain or loss.
 
    Exchanges of shares are subject to the other requirements of the
applicable fund into which exchanges are made. Annual fund operating expenses
for such other fund may be higher than the funds exchanged from.
 
    Automatic Monthly Investment Plan. Any shareholder may elect on the Share
Purchase Application to make additional investments in a Money Fund
automatically, by authorizing the Money Funds to draw on the shareholder's
designated bank account regularly by check.
 
    A shareholder may change the date (either the 10th, 15th or 20th of each
month) or amount (subject to a minimum of $25) of the shareholder's monthly
investment at any time by letter to the Money Funds at least three business
days before the change becomes effective. The plan may be terminated at any
time without penalty by the shareholder or the Money Funds.
 
    Automatic Exchange Plan. Shareholders may authorize Winthrop to exchange
an amount established in advance automatically for shares of the other Money
Fund or shares of the International Funds or Focus Funds on a monthly,
quarterly, semi-annual or annual basis under an Automatic Exchange Plan. The
minimum exchange into another Winthrop Fund under the Automatic Exchange Plan
is $50. These exchanges are subject to the terms of the Exchange Privilege
described above (see "Additional Shareholder Services -- Exchange Privilege").
 
    Dividend Direction Option. Shareholders may elect on the Share Purchase
Application to have their dividends paid to another individual or directed for
reinvestment into the other Money Fund or into the International Funds or
Focus Funds provided that an
 
                                      12
<PAGE>
 
 
existing account in such other fund is maintained by the shareholder.
 
    Systematic Withdrawal Plan. Any shareholder who owns or purchases shares
of a Money Fund having a current net asset value of at least $10,000 may
establish a systematic withdrawal plan under which the shareholder or a third
party will receive payment by check in a stated amount of not less than $50 on
a monthly, quarterly, semi-annual or annual basis. A contingent deferred sales
charge which may otherwise be imposed on a withdrawal redemption (via an
exchange from the International Funds or Focus Funds) will be waived in
connection with redemptions made pursuant to Winthrop's systematic withdrawal
plan up to 1% monthly or 3% quarterly of an account (excluding dividend
reinvestment) not to exceed 10% over any 12-month rolling period. Systematic
withdrawals elected on a semi-annual or annual basis are not eligible for the
waiver.
 
    Checkwriting Privileges. Shareholders may redeem shares by writing checks
against their account balance for at least $100. Investments in the Money
Funds will continue to earn dividends until a shareholder's check is presented
to the Money Funds for payment. Checks will be returned by the Money Funds'

Transfer Agent if there are insufficient shares to meet the withdrawal amount.
Shareholders should not attempt to close an account by check because the exact
balance at the time the check clears will not be known when the check is
written. There is currently no charge to shareholders for checkwriting, but
the Money Funds reserve the right to impose a charge in the future. The Money
Funds may modify, suspend or terminate checkwriting privileges at any time
upon notice to shareholders and will terminate checkwriting privileges without
notice for accounts whose assets are exchanged completely out of the Money
Funds. In addition, UMB Bank, n.a., as agent for the Transfer Agent in
processing redemptions via the checkwriting privilege, reserves the right to
terminate checkwriting privileges at any time without notice to shareholders.
Checkwriting privileges will not be available for accounts whose shares are
subject to a contingent deferred sales charge.
 
    Telephone Redemption and Exchange Privilege. A shareholder is eligible to
withdraw up to $50,000 per day from such shareholder's account, via telephone
orders (toll free) (800) 225-8011 given to the Money Funds by the shareholder
or the shareholder's investment dealer of record. A shareholder may also
exchange assets via telephone from such shareholder's account to the Class A
or Class B shares of the International Funds and Focus Funds. Each Money Fund
will employ reasonable procedures to confirm that instructions communicated by
telephone are genuine. Such procedures include the requirement that redemption
or exchange orders must include the account name and the account number as
registered with the Money Funds. The minimum amount for a wire transfer is
$1,000. Proceeds of telephone redemptions may also be sent by automated
clearing house funds to a shareholder's designated bank account. Neither the
Money Funds, the Adviser, the International Funds, the Focus Funds, nor any
transfer agent for any of the foregoing will be responsible for following
instructions communicated by telephone that are reasonably believed to be
genuine and, accordingly, investors bear the risk of loss. The Telephone
Exchange Privilege will be offered automatically unless a shareholder declines
such option on the Share Purchase Application or by writing to the Money
Funds' Transfer Agent at the address listed on the back cover page of this
Prospectus.
 
    Timing of Redemptions and Exchanges. If a redemption or exchange order for
a Money Fund is received on a Money Fund Business Day prior to the close of
the regular session of the NYSE, which is generally 4:00 p.m. New York City
time, the proceeds will be transferred as soon as possible, normally on the
next Money Fund Business Day, and shares of each Money Fund will be priced
that Money Fund Business Day. If the redemption or exchange order is received
after the close of the regular session of the NYSE, shares of each Money Fund
will be priced the next Money Fund Business Day and the proceeds will be
transferred the next Money Fund Business Day after pricing. A shareholder also
may request that proceeds be sent by check to a designated bank. Exchanges are
made without any charge by the Money Funds.
 
    Purchases by check may not be redeemed by a Money Fund until after a
reasonable time necessary to verify that the purchase check has been paid
(approximately ten Money Fund Business Days from receipt of
 
                                      13
<PAGE>
 

 
the purchase check). When a purchase is made by wire and subsequently
redeemed, the proceeds from such redemption normally will not be transmitted
until two Money Fund Business Days after the purchase by wire. Bank
acknowledgment of payment initialed by the shareholder may shorten delays.
    Additional information concerning these Additional Shareholder Services
may be obtained by contacting the Money Funds' Transfer Agent at the address
or telephone number listed on the back cover page of this Prospectus.
 
                               NET ASSET VALUE
 
    The net asset value per share for purchases and redemptions of shares of
each Money Fund is determined as of the close of the regular session of the
NYSE, which is generally 4:00 p.m., New York City time, on each day that
trading is conducted during such session on the NYSE. In accordance with the
Money Funds' Agreement and Declaration of Trust and By-Laws, net asset value
for each Money Fund is determined separately by dividing the value of each
Money Fund's assets less its liabilities, by the total number of each Fund's
shares then outstanding. The Net Asset Value is expected to be maintained at a
constant $1.00 per share although this price is not guaranteed. For purposes
of this computation, the securities in each Money Fund's portfolio are valued
at amortized cost, which minimizes the effect of changes in a security's
market value and helps maintain a stable $1.00 per share price. All expenses,
including the fees payable to the Adviser, are accrued daily.
 
    Events affecting the values of investments that occur between the time
their prices are determined and 4:00 p.m. on each day that the NYSE is open
will not be reflected in the net asset value of a Money Fund's shares unless
the Adviser, under the supervision of such Fund's Board of Trustees,
determines that the particular event would materially affect net asset value.
As a result, the net asset value of a Money Fund's shares may be significantly
affected by such trading on days when a shareholder has no access to such
Money Fund.
 
                   DAILY DIVIDENDS, DISTRIBUTIONS AND TAXES
 
    Dividends from net investment income are declared daily and paid monthly.
Net investment income consists of all accrued interest income on Money Fund
assets less the Money Fund's expenses applicable to that dividend period.
There is no fixed dividend rate and there can be no assurance that a Money
Fund will distribute any net investment income. The amount of any distribution
paid by each Money Fund depends upon the realization by the Money Fund of
income from that Money Fund's investments. All distributions will be made to
shareholders of a Money Fund solely from assets of that Money Fund.
 
    Distributions by the Money Funds may also be subject to certain state and
local taxes. Each year, by January 31, the Money Funds will send tax
information stating amount and type of all its distributions for the year just
ended.
 
    Each Money Fund intends to qualify as a regulated investment company under
Subchapter M of the Code, so that it will not be liable for federal income
taxes to the extent that its net taxable income and net capital gains are
distributed.

 
                               RETIREMENT PLANS
 
    Each of the Money Funds may be a suitable investment vehicle for part or
all of the assets held in various tax-sheltered retirement plans such as
Traditional, Educational and ROTH IRA's, SEP's, SIMPLE plans and other pension
and profit-sharing plans. Semper Trust Company serves as custodian under these
 
                                      14
 
<PAGE>
 
prototype retirement plans and charges an annual account maintenance fee of
$15 per participant, regardless of the number of Winthrop Funds selected.
Persons desiring information concerning these plans should write or telephone
the Money Funds or the Money Funds' Transfer Agent. For a more detailed

                             GENERAL INFORMATION
 
Capitalization
 
    The Opportunity Funds were organized as a Delaware business trust under
the laws of Delaware on May 31, 1995. The Opportunity Funds have an unlimited
number of authorized shares of beneficial interest, which may, without
shareholder approval, be divided into an unlimited number of series, and an
unlimited number of classes. The Opportunity Funds are currently divided into
the Money Funds and the International Funds, each of which are divided into
two series. Each share of each Money Fund is normally entitled to one vote
(with proportional voting for fractional shares). Generally, shares of both
Money Funds vote as a single series on matters that affect all Money Funds in
substantially the same manner. As to matters affecting each Money Fund
separately, such as approval of the investment advisory agreement, shares of
each Money Fund would vote as separate series. The Money Funds will not have
annual meetings of shareholders so long as at least two-thirds of the Trustees
then in office have been elected by the shareholders. Section 16(c) of the
1940 Act provides certain rights to shareholders which the Money Funds will
honor regarding the calling of meetings of shareholders and other
communications with shareholders. Trustees may also call meetings of
shareholders from time to time as the Trustees deem necessary or desirable.
 
    Shares of a Money Fund are freely transferable, are entitled to dividends
as determined by the Trustees and, in liquidation of a Money Fund, are
entitled to receive the net assets of that Money Fund. Shareholders have no
preemptive rights.
 
Distributor
 
    Donaldson, Lufkin & Jenrette Securities Corporation, an affiliate of the
Adviser, serves as the Money Funds' Distributor.
 
Custodian, Dividend Disbursing Agent and Transfer Agent
 

    Citibank, N.A. acts as Custodian for the securities and cash of the Money
Funds, but plays no part in deciding on the purchase or sale of portfolio
securities. FPS Services, Inc. acts as dividend disbursing agent, registrar
and transfer agent.
 
Information for Shareholders
 
    Any shareholder inquiry regarding the Money Funds or the status of the
shareholder's account can be made to the Money Funds by mail or by telephone
at the address or telephone number listed in front of this Prospectus or to
FPS Services, Inc. at the address on the back cover of this Prospectus.
 
    Following any purchase or redemption, a shareholder will receive a
statement confirming the transaction. Annual audited and semi-annual unaudited
financial statements, which include a list of investments held by the Money
Funds, will be sent to shareholders.
 
Year 2000 Compliance
 
    As the year 2000 approaches, an issue has emerged regarding how existing
application software programs and operating systems can distinguish between
the year 2000 and the year 1900. Failure to adequately address this issue
could have potentially serious repercussions to the Funds and their respective
shareholders as the Funds are dependent on the smooth functioning of the
computer software and operating systems of their respective Advisers,
Distributor, Custodian and Transfer Agent. The Adviser is in the process of
working with the Funds' service providers to prepare for the year 2000 and
expects that both it and such service providers will be year 2000 compliant on
a timely basis. As of the date of this Prospectus, the Funds do not expect
that they will incur significant operating expenses or be required to incur
material costs to be year 2000 compliant.

   other and with UMB Bank, n.a. ("Bank") that the Bank is appointed agent for
   such person(s) and, as such agent, is directed to request FPS Services,

   effected, in an amount less than stated in the Prospectus; (b) No check
   shall be issued or honored, or redemption effected, for any amounts
   represented by shares unless payment for such shares has been made in full
   and any checks given in such payment have been collected through normal
   banking channels; (c) No check shall be honored unless the Fund has
   provided the Bank, from the proceeds of redemption or otherwise, collected
   funds for the payment of such check; (d) Checks issued hereunder cannot be
   cashed over the counter at the Bank; and (e) Checks shall be subject to any

   hereunder unless the parties have indicated on the front of this card that
   not all Signatory(s) need sign, in which case the Bank and the Transfer
   Agent are authorized to act upon the indicated number of signatures, and
   (c) each Signatory guarantees to Bank and Transfer Agent the genuineness
   and accuracy of the signature of the other Signatory(s).
 
4. TERMINATION: The Bank may at any time terminate this account, related share

   prior notice by Bank to any of the Signatory(s). The Funds may terminate
   this checkwriting privilege in accordance with the procedures stated in the
   Prospectus.

                      INVESTMENT POLICIES AND RESTRICTIONS

   
     The following investment policies and restrictions supplement should be
read in conjunction with the information set forth under the heading "Investment

Objectives and Policies"  in the Money Funds' Prospectus. Except as noted in
the Prospectus and this Statement of Additional Information, the Money Funds'
investment policies are not fundamental and may be changed by the Trustees of
the Money Funds without shareholder approval; however, shareholders will be
notified prior to a significant change in such policies. The Money Funds'
investment restrictions which are fundamental and may not be changed without
shareholder approval are indicated under "Fundamental Investment Restrictions"
in this Statement of Additional Information.
    

     It is the policy of the Municipal Fund to seek maximum current income,
consistent with liquidity and safety of principal, that is exempt from Federal
income taxes by investing principally in a diversified portfolio of municipal
securities; it is the policy of the Government Fund to seek maximum current
income, consistent with liquidity and safety of principal, by investing in a
portfolio of U.S. Government securities. It is the policy of both Money Funds to
declare the net investment income associated with their investments as a daily
dividend to maintain the net asset value of the Funds at $1.00. (See "Net Asset
Value" and "Daily Dividends, Distributions and Taxes.") In addition, one or both
of the Money Funds may invest in the securities described below. The Prospectus
indicates which particular Money Fund is permitted to invest in, or may be
limited in investing in, the following securities.

Securities

     U.S. Government Obligations. The Money Funds may purchase marketable
obligations of, or guaranteed by, the United States Government, its agencies or
instrumentalities. These include issues of the United States Treasury, such as
bills, certificates of indebtedness, notes and bonds, and issues of agencies and
instrumentalities established under the authority of an act of Congress,
including variable rate obligations such as floating rate notes. The latter
issues include, but are not limited to, obligations of the Bank for
Cooperatives, Federal Financing Bank, Federal Home Loan Bank, Federal
Intermediate Credit Banks, Federal Land Banks, Federal National Mortgage
Association and Tennessee Valley Authority. Some of these securities are
supported by the full faith and credit of the United States Treasury, others are
supported by the right of the issuer to borrow from the Treasury, and still
others are supported only by the credit of the agency or instrumentality.

   
     Repurchase   Agreements.   The  Money  Funds  may  enter  into  "repurchase
agreements" with member banks of the Federal Reserve System,  "primary  dealers"
(as designated by the Federal  Reserve Bank of New York) in such  securities,  ^
any  domestic  or  foreign  broker/dealer  which is  recognized  as a  reporting
government securities dealer or any other counterparty allowable under Rule 2a-7
of the Investment Company Act of 1940 (the "Act").  Repurchase agreements permit
the Money Funds to keep all of their assets at work while retaining  "overnight"
flexibility in pursuit of investments of a longer-term  nature.  The Money Funds
require
    



                                       2

<PAGE>


   
continual maintenance of collateral with an approved custodian in an amount
equal to, or in excess of, the market value of the securities which are the
subject of a repurchase agreement. In the event a vendor defaults on its
repurchase obligation, the Money Funds might suffer a loss to the extent that
the proceeds from the sale of the collateral were less than the repurchase
price. If the vendor becomes the subject of bankruptcy proceedings, the Money
Funds might be delayed in selling the collateral. Pursuant to Rule 2a-7 of the ^
1940 Act, a repurchase agreement is deemed to be an acquisition of the
underlying securities provided that the obligation of the seller to repurchase
the securities from the Money Funds is collateralized fully (as defined in such
Rule). Accordingly, the vendor of a fully collateralized repurchase agreement is
deemed to be the issuer of the underlying securities.
    

     Reverse Repurchase Agreements. The Money Funds may also enter into reverse
repurchase agreements. Under a reverse repurchase agreement, the Money Funds
would sell securities and agree to repurchase them at a mutually agreed upon
date and price. At the time the Money Funds enter into a reverse repurchase
agreement, they would establish and maintain with an approved custodian a
segregated account containing liquid securities having a value not less than the
repurchase price. Reverse repurchase agreements involve the risk that the market
value of the securities subject to such agreement could decline below the
repurchase price to be paid by the Money Funds for such securities. In the event
the buyer of securities under a reverse repurchase agreement filed for
bankruptcy or became insolvent, such buyer or receiver would receive an
extension of time to determine whether to enforce the Money Funds' obligations
to repurchase the securities and the Money Funds' use of the proceeds of the
reverse repurchase could effectively be restricted pending such decision.
Reverse repurchase agreements create leverage, a speculative factor, but are not
considered senior securities by the Money Funds or the Securities and Exchange
Commission to the extent liquid debt securities are segregated in an amount at
least equal to the amount of the liability.

     When-Issued and Delayed-Delivery Securities. The Money Funds may, to the
extent consistent with their other investment policies and restrictions, enter
into forward commitments for the purchase or sale of securities, including on a
"when-issued" or "delayed-delivery" basis, in excess of customary settlement
periods for the type of security involved. In some cases, a forward commitment
may be conditioned upon the occurrence of a subsequent event, such as approval
and consummation of a merger, corporate reorganization or debt restructuring,
i.e., a when, as and if issued security.

     When such transactions are negotiated, the price is fixed at the time of
the commitment, with payment and delivery taking place in the future, generally
ten days to a month, or more, after the date of the commitment. While the Money
Funds will only enter into a forward commitment with the intention of actually
acquiring the security, the Money Funds may sell the security before the
settlement date if it is deemed advisable.



                                       3
<PAGE>


     Securities purchased under a forward commitment are subject to market
fluctuation, and no interest (or dividends) accrues to the Money Funds prior to
the settlement date. The Money Funds will segregate with their custodian cash or
liquid debt securities in an aggregate amount at least equal to the amount of
their respective outstanding forward commitments.

     Standby Commitments. The Municipal Fund may purchase municipal securities
together with the right to resell them to the seller at an agreed-upon price or
yield within specified periods prior to their maturity dates. Such a right to
resell is commonly known as a "standby commitment," and the aggregate price
which the Municipal Fund pays for securities with a standby commitment may be
higher than the price which otherwise would be paid. The primary purpose of this
practice is to permit the Municipal Fund to be as fully invested as practicable
in municipal securities while preserving the necessary flexibility and liquidity
to meet unanticipated redemptions. In this regard, the Municipal Fund acquires
standby commitments solely to facilitate liquidity and does not exercise its
rights thereunder for trading purposes. Since the value of a standby commitment
is dependent on the ability of the standby commitment writer to meet its
obligation to repurchase, the Municipal Fund's policy is to enter into standby
commitment transactions only with municipal securities dealers which are
determined to present minimal credit risks.

     The acquisition of a standby commitment does not affect the valuation or
maturity of the underlying municipal securities which continue to be valued in
accordance with the amortized cost method. Standby commitments acquired by the
Municipal Fund are valued at zero in determining net asset value. Where a
Municipal Fund pays directly or indirectly for a standby commitment, its cost is
reflected as unrealized depreciation for the period during which the commitment
is held. Standby commitments do not affect the average weighted maturity of the
Municipal Fund's portfolio of securities.

     Municipal Securities. The term "municipal securities," as used in the
Prospectus and this Statement of Additional Information, means obligations
issued by or on behalf of states, territories, and possessions of the United
States or their political subdivisions, agencies and instrumentalities, the
interest from which is exempt (subject to the alternative minimum tax - as later
described) from Federal income taxes. The municipal securities in which the
Municipal Fund invests are limited to those obligations which at the time of
purchase are:

     1.   Backed by the full faith and credit of the United States; or

     2.   Municipal notes rated MIG-1 or MIG-2 and VMIG-1 or VMIG-2, by Moody's
          Investors Service, Inc. ("Moody's") or SP-1 or SP-2 by Standard and
          Poor's Corporation ("S&P"), or, if not rated, are of equivalent
          investment quality as determined by the Municipal Fund's adviser; or

     3.   Municipal bonds rated Aa or higher by Moody's, AA- or higher by S&P
          or, if not rated, are of equivalent investment quality as determined
          by the Municipal Funds' adviser; or




                                       4
<PAGE>


     4.   Other types of municipal securities, provided that such obligations
          are rated Prime-1 by Moody's, A-1 or higher by S&P or, if not rated,
          are of equivalent investment quality as determined by the Municipal
          Fund's adviser.

See Appendix A for a description of municipal ratings and Appendix B for a
description of municipal securities.

     Alternative Minimum Tax. The Municipal Fund may invest without limitation
in tax-exempt municipal securities subject to the alternative minimum tax (the
"AMT"). Under current Federal income tax law, (1) interest on tax-exempt
municipal securities issued after August 7, 1986 which are "specified private
activity bonds," and the proportionate share of any exempt-interest dividend
paid by a regulated investment company which receives interest from such
specified private activity bonds will be treated as an item of tax preference
for purposes of the AMT imposed on individuals and corporations, though for
regular Federal income tax purposes, such interest will remain fully tax-exempt,
and (2) interest on all tax-exempt obligations will be included in "adjusted
current earnings" for corporation for AMT purposes. Such private activity bonds
("AMT-Subject Bonds") have provided, and may continue to provide, somewhat
higher yields than other comparable municipal securities.

     Investors should consider that, in most instances, no state, municipality
or other governmental unit with taxing power will be obligated with respect to
AMT-Subject Bonds. AMT-Subject Bonds are in most cases revenue bonds and do not
generally have the pledge of the credit or the taxing power, if any, of the
issuer of such bonds. AMT-Subject Bonds are generally limited obligations of the
issuer supported by payments from private business entities and not by the full
faith and credit of a state or any governmental subdivision. Typically the
obligation of the issuer of an AMT-Subject Bond is to make payments to bond
holders only out of, and to the extent of, payments made by the private business
entity for whose benefit the AMT-Subject Bonds were issued. Payment of the
principal and interest on such revenue bonds depends solely on the ability of
the user of the facilities financed by the bonds to meet its financial
obligations and the pledge, if any, of real and personal property so financed as
security for such payment. It is not possible to provide specific detail on each
of these obligations in which Municipal Fund assets may be invested.

     While the Municipal Fund may invest without limitation in securities
subject to AMT, the AMT affects only a small percentage of all taxpaying
investors.

     Taxable Securities for the Municipal Fund. The Municipal Fund is, and
expects to be, largely invested in municipal securities, but may elect to invest
up to 20% of its total assets in taxable money market securities when such
action is deemed to be in the best interests of shareholders. Such taxable money
market securities also are limited to remaining maturities of 397 days or less

at the time of the Municipal Fund's investment, and the Municipal Fund's
municipal and taxable securities are maintained at a dollar-weighted average of
90 days or less.



                                       5
<PAGE>


     Variable Rate Obligations. The interest rate payable on certain municipal
securities in which the Municipal Fund may invest, called "variable rate"
obligations, is not fixed and may fluctuate based upon changes in market rates.
The interest rate payable on a variable rate municipal security is adjusted
either at pre-designated periodic intervals or whenever there is a change in the
market rate to which the security's interest rate is tied. Other features may
include the right of the Municipal Fund to demand prepayment of the principal
amount of the obligation prior to its stated maturity and the right of the
issuer to prepay the principal amount prior to maturity. The main benefit of a
variable rate municipal security is that the interest rate adjustment minimizes
changes in the market value of the obligation. As a result, the purchase of
variable rate municipal securities enhances the ability of the Municipal Fund to
maintain a stable net asset value per share and to sell an obligation prior to
maturity at a price approximating the full principal amount. The payment of
principal and interest by issuers of certain municipal securities purchased by
the Municipal Fund may be guaranteed by letters of credit or other credit
facilities offered by banking or other financial institutions. Such guarantees
will be considered in determining whether a municipal security meets the
Municipal Fund's investment quality requirements.

     Variable rate obligations purchased by the Municipal Fund may include
participation interests in variable rate industrial development bonds. Purchase
of a participation interest gives the Municipal Fund an undivided interest in
certain such bonds. The Municipal Fund can exercise the right, on not more than
30 days' notice, to sell such an instrument back to the financial institution
from which it purchased the instrument and, if applicable, draw on the letter of
credit for all or any part of the principal amount of the Municipal Fund's
participation interest in the instrument, plus accrued interest, but will do so
only (i) as required to provide liquidity to the Municipal Fund, (ii) to
maintain a high quality investment portfolio, or (iii) upon a default under the
terms of the demand instrument. Financial institutions retain portions of the
interest paid on such variable rate industrial development bonds as their fees
for servicing such instruments and the issuance of related letters of credit and
repurchase commitments. No single financial institution will issue its letters
of credit with respect to variable rate obligations or participation interests
therein covering more than the allowable percentage of the total assets of the
Municipal Fund pursuant to Rule 2a-7 of the Act. The Municipal Fund will not
purchase participation interests in variable rate industrial development bonds
unless it receives an opinion of counsel or a ruling of the Internal Revenue
Service that interest earned by the Municipal Fund from the bonds in which it
holds participation interests is exempt from Federal income taxes. The Municipal
Fund's adviser will monitor the pricing, quality and liquidity of variable rate
demand obligations and participation interests therein held by the Municipal
Fund on the basis of published financial information, rating agency reports and

other research services to which the adviser may subscribe.



     Municipal Leases and Participations Therein. These are obligations in the
form of a lease or installment purchase which is issued by state and local
governments to acquire equipment and facilities. Income from such obligations is
exempt from local and state taxes in the state of issuance. "Participations" in
such leases are undivided interests in a portion of the total obligation.
Municipal leases frequently have special risks not normally associated with
general obligation or 



                                       6
<PAGE>


revenue bonds. The constitutions and statutes of all states contain requirements
that the state or a municipality must meet to incur debt. These often include
voter referenda, interest rate limits and public sale requirements. Leases and
installment purchase or conditional sale contracts (which normally provide for
title to the leased asset to pass eventually to the governmental issuer) have
evolved as a means for governmental issuers to acquire property and equipment
without meeting the constitutional and statutory requirements for the issuance
of debt. The debt-issuance limitations are deemed to be inapplicable because of
the inclusion in many leases or contracts of "non-appropriation" clauses that
provide that the governmental issuer has no obligation to make future payments
under the lease or contract unless money is appropriated for such purpose by the
appropriate legislative body on a yearly or other periodic basis.

     In addition to the "non-appropriation" risk, municipal leases have
additional risk aspects because they represent a relatively new type of
financing that has not yet developed in many cases the depth of marketability
and liquidity associated with conventional bonds; moreover, although the
obligations will be secured by the leased equipment, the disposition of the
equipment in the event of non-appropriation or foreclosure might, in some cases,
prove difficult. In addition, in certain instances the tax-exempt status of the
obligations will not be subject to the legal opinion of a nationally recognized
"bond counsel," as is customarily required in larger issues of municipal
obligations. However, in all cases the Municipal Fund will require that a
municipal lease purchased by the Municipal Fund be covered by a legal opinion
(typically from the issuer's counsel) to the effect that, as of the effective
date of such lease, the lease is the valid and binding obligation of the
governmental issuer.

     Municipal leases and participations will be purchased pursuant to analysis
and review procedures which the Municipal Fund's adviser believes will minimize
risks to shareholders. It is possible that more than 5% of the Fund's net assets
will be invested in municipal leases which have been determined by the Municipal
Fund's adviser to be liquid securities. When evaluating the liquidity of a
municipal lease, the investment adviser considers all relevant factors including
frequency of trading, availability of quotations, the number of dealers and
their willingness to make markets, the nature of trading activity and the

assurance that liquidity will be maintained. With respect to unrated municipal
leases, credit quality is also evaluated.

     General. Net income to shareholders is aided both by the Money Funds'
ability to make investments in large denominations and by its efficiencies of
scale. Also, the Money Funds may seek to improve its income by selling certain
portfolio securities prior to maturity in order to take advantage of yield
disparities that occur in money markets. The market value of the Money Funds'
investments tends to decrease during periods of rising interest rates and to
increase during intervals of falling rates.

Rule 2a-7 Under the Investment Company Act of 1940

     The Money Funds will comply with Rule 2a-7 under the Act, as amended from
time to time, including the diversity, quality and maturity limitations imposed
by the Rule.



                                       7
<PAGE>


     Currently, pursuant to Rule 2a-7, the Money Funds may invest only in
"eligible securities," as that term is defined in the Rule. Generally, an
eligible security is a security that (i) is denominated in U.S. Dollars and has
a remaining maturity of 397 days or less; (ii) is rated, or is issued by an
issuer with short-term debt outstanding that is rated, in one of the two highest
rating categories by two nationally recognized statistical rating organizations
("Rating Organizations") or, if only one has issued a rating, by that Rating
Organization; and (iii) has been determined by the Money Funds' adviser to
present minimal credit risks. A security that originally had a maturity of
greater than 397 days is an eligible security if its remaining maturity at the
time of purchase is 397 calendar days or less and the issuer has outstanding
short-term debt that would be an eligible security. Unrated securities may also
be eligible securities if the Money Funds' adviser determines that they are of
comparable quality to a rated eligible security pursuant to guidelines approved
by the Trustees. A description of the ratings of some Rating Organizations
appears in Appendix A attached hereto.

     Under Rule 2a-7, the Money Funds may not invest more than 5% of its assets
in the securities of any one issuer other than the United States Government, its
agencies or instrumentalities. In addition, the Money Funds may not invest in a
security that has received, or is deemed comparable in quality to a security
that has received, the second highest rating by the requisite number of Rating
Organizations (a "second tier security") if immediately after the acquisition
thereof the Money Funds would have invested more than (A) the greater of one
percent of its total assets or one million dollars in securities issued by that
issuer which are second tier securities, or (B) five percent of its total assets
in second tier securities.

     Securities with a settlement of more than seven days from the date of
purchase, as calculated pursuant to Rule 2a-7, are considered by the Securities
and Exchange Commission to be illiquid securities in an open-end investment

company. The Money Funds are restricted to invest no more than 10% of their net
assets in illiquid securities.

Other General Information About the Municipal Fund

     Yields on municipal securities are dependent on a variety of factors,
including the general condition of the money market and of the municipal bond
and municipal note market, the size of a particular offer, the maturity of the
obligation and the rating of the issue. Municipal securities with longer
maturities tend to produce higher yields and are generally subject to greater
price movements than obligations with shorter maturities. (An increase in
interest rates will generally reduce the market value of portfolio investments,
and a decline in interest rates will generally increase the value of portfolio
investments.) The achievement of the Municipal Fund's investment objectives is
dependent in part on the continuing ability of the issuers of municipal
securities in which the Municipal Fund invests to meet their obligations for the
payment of principal and interest when due. Municipal securities historically
have not been subject to registration with the Securities and Exchange
Commission, although there have been proposals which would require registration
in the future. The Municipal Fund may seek to improve income 



                                       8
<PAGE>


by selling certain securities prior to maturity in order to take advantage of
yield disparities that occur in securities markets.

     Obligations of issuers of municipal securities are subject to the
provisions of bankruptcy, insolvency, and other laws affecting the rights and
remedies of creditors, such as the Bankruptcy Code. In addition, the obligations
of such issuers may become subject to laws enacted in the future by Congress,
state legislatures, or referenda extending the time for payment of principal
and/or interest, or imposing other constraints upon enforcement of such
obligations or upon the ability of municipalities to levy taxes. There is also
the possibility that, as a result of litigation or other conditions, the ability
of any issuer to pay, when due, the principal of, and interest on, its municipal
securities may be materially affected.

Fundamental Investment Restrictions

     The following fundamental investment restrictions are applicable to each of
the Money Funds and may not be changed with respect to a Money Fund without the
approval of a majority of the shareholders of that Money Fund, which means the
affirmative vote of the holders of (a) 67% or more of the shares of that Money
Fund represented at a meeting at which more than 50% of the outstanding shares
of the Money Fund are represented or (b) more than 50% of the outstanding shares
of that Money Fund, whichever is less. Except as set forth in the Prospectus and
this Statement of Additional Information, all other investment policies or
practices are considered by each Money Fund not to be fundamental and
accordingly may be changed without shareholder approval. If a percentage
restriction is adhered to at the time of investment, a later increase or

decrease in percentage resulting from a change in values or assets will not
constitute a violation of such restriction.

     Briefly, these fundamental restrictions provide that each Money Fund may
     not:

          (1) Invest 25% or more of the value of its total assets in any one
     industry, other than the United States Government, or any of its agencies
     or instrumentalities, provided that, for purposes of this policy, consumer
     finance companies, industrial finance companies and gas, electric, water
     and telephone utility companies are each considered to be separate
     industries;

          (2) Issue senior securities, except as permitted under the Investment
     Company Act of 1940;

          (3) Make loans of money or property to any person, except through
     loans of portfolio securities, the purchase of fixed income securities
     consistent with the Money Funds' investment objective and policies or the
     acquisition of securities subject to repurchase agreements;



                                       9
<PAGE>


          (4) Underwrite the securities of other issuers, except to the extent
     that in connection with the disposition of portfolio securities the Money
     Funds may be deemed to be an underwriter;

          (5) Purchase real estate or interests therein unless acquired as a
     result of ownership from investing in securities or other instruments (but
     this shall not prevent the Money Funds from investing in securities or
     other interests backed by real estate or securities of companies engaged in
     the real estate business);

          (6) Purchase or sell commodities or commodities contracts except for
     purposes, and only to the extent, permitted by applicable law without the
     Money Funds becoming subject to registration with the Commodity and Futures
     Trading Commission as a commodity pool;

          (7) Make any short sale of securities except in conformity with
     applicable laws, rules and regulations and unless, giving effect to such
     sale, the market value of all securities sold short does not exceed 25% of
     the value of the Money Fund's total assets and the Money Fund's aggregate
     short sales of a particular class of securities does not exceed 25% of then
     outstanding securities of that class; and

          (8) Borrow money, except that the Money Funds may (i) borrow money for
     temporary or emergency purposes (not for leveraging or investment) and (ii)
     engage in reverse repurchase agreements for any purpose; provided that (i)
     and (ii) in combination do not exceed 33 1/3% of the Money Fund's total
     assets (including the amount borrowed) less liabilities (other than

     borrowings). Any borrowings that come to exceed this amount will be reduced
     within three days (not including Sundays and holidays) to the extent
     necessary to comply with the 33 1/3% limitation.

Adviser

     DLJ Investment Management Corp. (the "Adviser"), a Delaware corporation
with principal offices at 277 Park Avenue, New York, New York 10172, has been
retained under an Investment Advisory Agreement as the Money Funds' investment
adviser (see "Management" in the Prospectus). The Adviser was established in
1996 to serve a select group of individual and institutional investors.

- ----------
     1    The Opportunity Funds anticipate paying each independent Trustee
          approximately $10,000 in each calendar year.

     2    Represents the total compensation paid to such persons during the
          calendar year ending December 31, 1997. The parenthetical number
          represents the number of portfolios (including the Money Funds) for
          which such person acts as a Trustee, that are considered part of the
          same fund complex as the Money Funds.



                                       12
<PAGE>


   
     The Adviser is a wholly-owned subsidiary of Donaldson, Lufkin & Jenrette
Securities Corporation ("DLJ Securities" or the "Distributor"), the distributor
of the Funds' shares, which is a wholly-owned subsidiary of Donaldson, Lufkin &
Jenrette, Inc., which is in turn an independently operated, indirect subsidiary
of The Equitable Companies, Incorporated ("ECI"), a holding company controlled
by AXA-UAP ("AXA"), a French insurance holding company. The Adviser along with
its affiliates are an integral part of the DLJ Securities family, and as one of
the oldest money management firms in the country, they maintain a tradition of
personalized service and performance. The address of Donaldson, Lufkin &
Jenrette, Inc. is 277 Park Avenue, New York, New York 10172. The address of ECI
is 787 Seventh Avenue, New York, New York 10019.

     As of July 1, 1997, AXA owns 60.5% of the outstanding shares of the common
stock of ECI. AXA is the holding company for an international group of insurance
and related financial services companies. AXA's insurance operations are
comprised of activities in life insurance, property and casualty insurance and
reinsurance. The insurance operations are diverse geographically with activities
in France, the United States, the United Kingdom, Canada and other countries,
principally in Europe. AXA is also engaged in asset management, investment
banking and brokerage, real estate and other financial services activities in
the United States and Europe. Based on information provided by AXA, on July 1,
1997, 18.2% of the issued ordinary shares (representing 28.2% of the voting
power) of AXA were directly or indirectly owned by Finaxa, a French holding
company ("Finaxa"). Such percentage of interest includes the interest of Colisee
Vendome, a wholly-owned subsidiary of Finaxa, which owned 3.1% of the issued
ordinary shares (representing 2.7% of the voting power) of AXA and the interest
of les Ateliers de construction du Nord de la France- ANF ("ANF"), a 95.4% owned
subsidiary of Finaxa, which owned 0.2% of the issued ordinary shares
(representing 0.3% of the voting power) of AXA. As of July 1, 1997, 61.5% of the
issued ordinary shares (representing 72.3% of the voting power) of Finaxa were
owned by four French mutual insurance companies (the "Mutuelles AXA")  and
23.7% of the issued ordinary shares (representing 14.7% of the voting power) of
Finaxa were owned by Banque Paribas, a French bank ("Paribas"). Including the
ordinary shares owned by Finaxa and its subsidiaries on July 1, 1997, the
Mutuelles AXA directly and indirectly owned 24.8% of the issued ordinary shares
of AXA (representing 35.9% of the voting power). Acting as a group, the
Mutuelles AXA will continue to control AXA and Finaxa.
    

     The Investment Advisory Agreement dated October 22, 1996 (the "Investment
Advisory Agreement") was approved by the Board of Trustees of the Winthrop
Opportunity Funds on October 22, 1996 and by the then shareholders on January
24, 1997 and became effective on the same date. The Investment Advisory
Agreement is reviewed annually by the Board of Trustees and was most recently
reapproved on July 17, 1997. The Investment Advisory Agreement continues in
force for successive twelve month periods provided that such continuation is
specifically approved at least annually by a majority vote of the Trustees who
neither are interested persons of the Funds nor have any direct or indirect

financial interest in the Investment Advisory Agreement, cast in person at a
meeting called for the purpose of voting on such approval. Under the Investment
Advisory Agreement, the Adviser is paid a management fee equal to .40 of 1% of
the average daily 



                                       13
<PAGE>


net assets of the Money Funds which are reduced to .35% of the average daily net
assets in excess of $1 billion.

     Pursuant to the terms of the Investment Advisory Agreement, the Adviser may
retain, at its own expense, a subadviser to assist in the performance of its
services to the Money Funds.

   
     For the period from the inception of the Money Funds on February 24, 1997
through October 31, 1997, the Municipal Fund and the Government Fund paid the
Adviser fees of $80,171 and $68,375, respectively.

     The Fund intends to enter into arrangements with certain broker-dealers
(including affiliates of the Distributor) whose customers are Fund shareholders
pursuant to which the broker-dealers may perform shareholder servicing 
functions, such as opening new shareholder accounts, processing purchase and 
redemption transactions, and responding to certain inquiries regarding the 
Fund's performance and the status of shareholder accounts. The Fund may pay 
for the electronic communications equipment maintained at the broker-dealers' 
offices that permits access to the Fund's computer files and, in addition, may 
reimburse the broker-dealers at cost for personnel expenses involved in 
providing the services.

    

                           EXPENSES OF THE MONEY FUNDS

General

     In addition to the payments to the Adviser under the Investment Advisory
Agreement, each Money Fund pays the other expenses incurred in its organization
and operations, including the costs of printing prospectuses and other reports
to existing shareholders; all expenses and fees related to registration and
filing with the Securities and Exchange Commission and with state regulatory
authorities; custody, transfer and dividend disbursing expenses; legal and
auditing costs; clerical, accounting and other office costs; fees and expenses
of Trustees who are not affiliated with the Adviser; costs of maintenance of
existence; and interest charges, taxes, brokerage fees and commissions.

     As to the obtaining of clerical and accounting services not required to be
provided to the Money Funds by the Adviser under the Investment Advisory
Agreement, the Money Funds may employ their own personnel. For such services,
they also may utilize personnel employed by the Adviser or their affiliates. In

such event, the services shall be provided to the Money Funds at cost and the
payments therefor must be specifically approved in advance by the Money Funds'
Trustees, including a majority of its disinterested Trustees.



                                       14

Distribution Agreement

     Pursuant to Rule 12b-1 adopted by the Securities and Exchange Commission
under the Act, the Money Funds have adopted a Distribution Agreement (the
"Distribution Agreement") and a Rule 12b-1 Plan for each Money Fund (the "12b-1
Plans") to permit such Money Fund directly or indirectly to pay expenses
associated with the distribution of shares.

     Pursuant to the Distribution Agreement and the 12b-1 Plans, the Treasurer
of the Money Funds reports the amounts expended under the Distribution Agreement
and the purposes for which such expenditures were made to the Trustees of the
Money Funds on a quarterly basis. Also, the 12b-1 Plans provide that the
selection and nomination of disinterested Trustees (as defined in the Act) are
committed to the discretion of the disinterested Trustees then in office. The
Distribution Agreement and 12b-1 Plans may be continued annually if approved by
a majority vote of the Trustees, including a majority of the Trustees who
neither are interested persons of the Money Funds nor have any direct or
indirect financial interest in the Distribution Agreement, the 12b-1 Plans or in
any other agreements related to the 12b-1 Plans, cast in person at a meeting
called for the purpose of voting on such approval. The Distribution Agreement
was initially approved by each Money Fund's Trustees on October 22, 1996 and by
the then shareholders on January 24, 1997. The Distribution Agreement was most
recently reviewed and reapproved on July 17, 1997. All material amendments to
the 12b-1 Plans must be approved by a vote of the Trustees, including a majority
of the Trustees who neither are interested persons of the Money Funds nor have
any direct or indirect financial interest in the 12b-1 Plans or any related
agreement, cast in person at a meeting called for the purpose of voting on such
approval. Each Money Fund's 12b-1 Plan may be terminated without penalty at any
time by a majority vote of the disinterested Trustees, by a majority vote of the
outstanding shares of a Money Fund or by the Adviser. Any agreement related to
the 12b-1 Plans may be terminated at any time, without payment of any penalty,
by a majority vote of the independent Trustees or by majority vote of the
outstanding shares of a Money Fund on not more than 60 days notice to any other
party to the agreement, and any agreement, but not the 12b-1 Plans, will
terminate automatically in the event of assignment.

     An initial concession or ongoing maintenance fee may be paid to
broker-dealers on sales of both Money Funds' shares. Pursuant to the Money
Funds' 12b-1 Plans, if such fee is paid, the Distributor is then reimbursed for
such payments with amounts paid from the assets of such Money Fund. The payments
to the broker-dealer, although a Money Fund expense which is paid by all
shareholders, will only directly benefit investors who purchase their shares
through a broker-dealer rather than from the Money Funds. Broker-dealers who
sell shares of the Money Funds may provide services to their customers that are

not available to investors who purchase their shares directly from the Money
Funds. Investors who purchase their shares directly from a Money Fund will pay a
pro rata share of such Money Fund's expenses of encouraging broker-dealers to
provide such services but not receive any of the direct benefits of such
services. The payments to the broker-dealers will continue to be paid for as
long as the related assets remain in the Money Funds.



                                       15
<PAGE>


     Pursuant to the provisions of the 12b-1 Plans and the Distribution
Agreement, the maximum amount payable by the Money Funds under the 12b-1 Plans
for distributing shares is .40 of 1% of the average daily net assets during the
fiscal year. Currently, each Money Fund pays a distribution services fee each
month to the Distributor, with respect to shares of each Money Fund, at an
annual rate of up to .25 of 1% of the aggregate average daily net assets
attributable to each Money Fund.

                      PURCHASES, REDEMPTIONS AND EXCHANGES

     The following information supplements that set forth in the Money Funds'
Prospectus under the heading "Purchases, Redemptions and Shareholder Services."

Purchases

     Shares of the Money Funds are offered at the respective net asset value per
share next determined following receipt of a purchase order in proper form by
the Money Funds, the Money Funds' transfer agent, FPS Services, Inc. (the
"Transfer Agent"), or by the Distributor. The Money Funds calculate net asset
value per share as of the close of the regular session of the New York Stock
Exchange, which is generally 4:00 p.m. New York City time on each day that
trading is conducted on the New York Stock Exchange (the "NYSE") (see "Net Asset
Value").

     Orders for the purchase of shares of a Money Fund become effective at the
next transaction time (as stated in the Prospectus) after Federal funds or bank
wire monies become available to the Transfer Agent for a shareholder's
investment. Federal funds are a bank's deposits in a Federal Reserve Bank. These
funds can be transferred by Federal Reserve wire from the account of one member
bank to that of another member bank on the same day and are considered to be
immediately available funds. Investors should note that their banks may impose a
charge for this service. Money transmitted by a check drawn on a member of the
Federal Reserve System is converted to Federal funds in one business day
following receipt. Checks drawn on banks which are not members of the Federal
Reserve System may take longer. All payments (including checks from individual
investors) must be in United States dollars. All shares purchased are confirmed
to each shareholder and are credited to such shareholder's account at net asset
value. To avoid unnecessary expense to the Money Funds, share certificates
representing shares of the Money Fund purchased are not issued for full or
fractional shares.


   
     Shareholders maintaining Fund accounts through brokerage firms and other
institutions should be aware that such institutions may necessarily set
deadlines for receipt of transaction orders from their clients that are earlier
than the transaction times of the Fund itself so that the institutions may
properly process such orders prior to their transmittal to the Fund or the
Distributor. Should an investor place a transaction order with such an
institution after its deadline, the institution may not effect the order with
the Fund until the next business day. Accordingly, an investor should
familiarize himself or herself with the deadlines set by his or her institution.
(For example, a brokerage firm may accept purchase orders from its customers up
to 
    



                                       16
<PAGE>


   
2:15 p.m. for issuance at the 4:00 p.m. transaction time and price.) A brokerage
firm acting on behalf of a customer in connection with transactions in Fund
shares is subject to the same legal obligations imposed on it generally in
connection with transactions in securities for a customer, including the
obligation to act promptly and accurately.
    

Redemptions

     Shares of the Money Funds may be redeemed at a redemption price equal to
the net asset value per share, as next computed as of the closing of the regular
trading session of the NYSE following the receipt in proper form by the Money
Fund of the shares tendered for redemption.

     Payment of the redemption price may be made either in cash or in portfolio
securities (selected in the discretion of the Trustees and taken at their value
used in determining the redemption price), or partly in cash and partly in
portfolio securities. However, payments will be made wholly in cash unless the
Trustees believe that an appropriate situation exists which would make such a
practice detrimental to the best interest of the Money Funds or its
shareholders. If payment for shares redeemed is made wholly or partly in
portfolio securities, brokerage costs may be incurred by the investor in
converting the securities to cash.

     To redeem shares, the registered owner or owners should forward a letter to
the Money Funds containing a request for redemption of such shares at the next
determined net asset value per share. Alternatively, the shareholder may elect
the right to redeem shares by telephone as described in the Prospectus. The
signature or signatures in the redemption letter must be guaranteed in the
manner described below.

     If the total value of the shares being redeemed exceeds $50,000 or a
redemption request directs proceeds to a party other than the registered account

owner(s), the signature or signatures on the letter or the endorsement must be
guaranteed by an "eligible guarantor institution" as defined in Rule 17Ad-15
under the Securities Exchange Act of 1934. Eligible guarantor institutions
include banks, brokers, dealers, credit unions, national securities exchanges,
registered securities associations, clearing agencies and savings associations.
A broker-dealer guaranteeing signatures must be a member of a clearing
corporation or maintain net capital of at least $100,000. Credit unions must be
authorized to issue signature guarantees. Signature guarantees will be accepted
from any eligible guarantor institution which participates in a signature
guarantee program. Additional documents may be required for redemption of
corporate, partnership or fiduciary accounts.

     The requirement for a guaranteed signature is for the protection of the
shareholder in that it is intended to prevent an unauthorized person from
redeeming his shares and obtaining the redemption proceeds.

Exchanges

   
     Shares of each Money Fund can be exchanged for shares of the other Money
Fund. Shareholders whose initial investment was directly into a Money Fund may
exchange such shares into either class of the (i) Winthrop Developing Markets
Fund or the Winthrop International Equity Fund, both series of the Winthrop
Opportunity Funds (the "International Funds") or (ii) Winthrop Growth Fund,
Winthrop Fixed Income Fund, Winthrop Small Company Value Fund, Winthrop Growth
and Income Fund and Winthrop Municipal Trust Fund (collectively, the "Focus
Funds"). Shares of each Money Fund established pursuant to Winthrop's exchange
privilege will be eligible for exchange into the International Funds or Focus
Funds provided that the exchange is directed into the same class of shares upon
which the initial investment was made. Shareholders may exchange shares by mail.
Shareholders or the shareholders' investment dealer of record may exchange
shares by telephone.
    

     In the case of the International Funds or the Focus Funds, the exchange
privilege is available only in those jurisdictions where shares of such fund may
be legally sold and is subject to the restrictions stated under "Additional
Shareholder Services-Exchange Privilege" in the Prospectus. In addition, the
exchange privilege is available only when payment for the shares to be redeemed
has been made.

     Only those shareholders who have had shares in a Money Fund for at least
seven days may exchange all or part of those shares for shares of the
International Funds or the Focus Funds, and no partial exchange may be made if,
as a result, the shareholders' interest in a Money Fund would be reduced to less
than $250. The minimum initial exchange into the International Funds or Focus
Funds is $250.


     All exchanges are subject to the minimum investment requirements and any
other applicable terms set forth in the Prospectus for the relevant fund or
class whose shares are being acquired. If for these or other reasons the
exchange cannot be effected, the shareholder will be so notified.

     The exchange privilege is intended to provide shareholders with a
convenient way to switch their investments when their objectives or perceived
market conditions suggest a change. The exchange privilege is not meant to
afford shareholders an investment vehicle to play short term swings in the stock
market by engaging in frequent transactions in and out of the International
Funds and the Focus Funds. Shareholders who engage in such frequent transactions
may be prohibited from or restricted in placing future exchange orders.

   
     Exchanges of shares are subject to the other requirements of the fund into
which exchanges are made. Annual fund operating expenses and distribution fees
for such fund may be higher and a sales charge differential may apply. See
"Expenses of the Money Funds" and "Additional Shareholder Services - Exchange
Privilege" in the Prospectus for a description of these expense differences.

                                RETIREMENT PLANS
   
     The Government Fund may be a suitable investment vehicle for part or all of
the assets held in various tax sheltered retirement plans, such as those listed
below. Semper Trust Company serves as custodian under these prototype retirement
plans and charges an annual account maintenance fee of $15 per participant,
regardless of the number of Funds selected. Persons desiring information
concerning these plans should write or telephone the Money Funds' Transfer
Agent. While the Government Fund reserves the right to suspend sales  of its
shares in response to conditions in the securities markets or for other reasons,
it is anticipated that any such suspension of sales would not apply to the types
of plans listed below.
    
Individual Retirement Accounts ("IRA")

   
     The Adviser has available a prototype form of a Traditional IRA. Under the
Code, individuals may currently make IRA contributions of up to $2,000 annually.
Married individuals filing jointly may contribute up to $2,000 for each spouse
if the combined compensation of both spouses is at least equal to the
contributed amount. Contributions to an IRA may be wholly or partly tax-
deductible, depending upon the contributor's income level and participation in
an employer-sponsored retirement plan. The income earned on shares held in an
IRA is not subject to Federal income tax until withdrawn in accordance with the
Code. Investors may be subject to penalties or additional taxes on contributions
to or withdrawals from IRAs under certain circumstances. As with tax-deductible
contributions, taxes on the income earned from nondeductible IRA contributions
will be deferred until distributed from the IRA.
    


     The Adviser has availabe a prototype form of the new Roth IRA. Unlike 
Traditional IRA's, contributions to a Roth IRA are not currently deductible.
However, the amounts within the Roth IRA accounts will accumulate tax-free, and
qualified distributions from the Money Funds will not be included in a
shareholder's taxable income. An individual may contribute a maximum of $2,000
annually to a Roth IRA ($4,000 for joint returns). However, such limit is
calculated in the aggregate with contributions to traditional IRA's. In
addition, Roth IRA's are not available to individuals above certain income
levels.

   
     The Adviser also has available a prototype form of the new Education IRA.
Like the Roth IRA, contributions are not currently deductible. However, the
investment earnings accumulate tax-free, and qualifying distributions used for
higher education expenses are not taxable. An individual may contribute a
maximum of $500 per account annually. In addition, Educational IRA's are not
available to individuals above certain income levels.

Simplified Employee Pension Plan ("SEP/IRA")

     A SEP/IRA is available for investment and may be established on a group
basis by an employer who wishes to sponsor a tax-sheltered retirement program by
making IRA contributions on behalf of all eligible employees.

Savings Incentive Match Plan for Employees ("SIMPLE") - SIMPLE IRA and SIMPLE
401(k)

     SIMPLE plans offer employers with 100 or fewer eligible employees who
earned at least $5,000 from the preceding calendar year the ability to 
establish a retirement plan that permits employee contributions. An employer 
may also elect to make additional contributions to these Plans. Please 
telephone Winthrop's shareholder servicing representatives at (800) 225-8011 for
more information.

Employer-Sponsored Retirement Plans

     The Adviser has a prototype retirement plan available which provides for
investment of plan assets in shares of any one or more Money Funds. The
prototype retirement plan may be used by sole proprietors and partnerships as
well as corporations to establish a tax qualified profit sharing plan or money
purchase pension plan (or both) of their own.


     Under the prototype retirement plan, an employer may make annual
tax-deductible contributions for allocation to the accounts of the plan
participants to the maximum extent permitted by the federal tax law for the type
of plan implemented. The Adviser has received favorable opinion letters from the
IRS that the prototype retirement plan is acceptable by qualified employers.

Self-Directed Retirement Plans

     Shares of the Money Funds may be suitable for self-directed IRA accounts
and prototype retirement plans such as those developed by Donaldson, Lufkin &
Jenrette Securities Corporation, an affiliate of the Adviser and Winthrop's
Distributor.

                                 NET ASSET VALUE

   
     Shares of the Money Funds will be priced at the net asset value per share
as computed each Money Fund Business Day in accordance with the Agreement and
Declaration of Trust and By-Laws. For this purpose, a Money Fund Business Day is
any day on which the NYSE is open for business, typically, Monday through Friday
exclusive of New Year's Day, Martin Luther King Jr. Day, Washington's Birthday,
Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and
Christmas Day.
    

     The net asset value of the shares of each Money Fund is determined as of
the close of the regular session on the NYSE, which is generally at 4:00 p.m.,
New York City time, on each day that trading is conducted on the NYSE. The net
asset value per share is calculated by taking the

sum of the value of each Money Fund's investments and any cash or other assets,
subtracting liabilities, and dividing by the total number of shares outstanding.
All expenses, including the fees payable to the Adviser, are accrued daily. For
purposes of this computation, the securities in each Money Fund's portfolio are
valued at their amortized cost, which does not take into account unrealized
securities gains or losses as measured by market valuations. The amortized cost
method involves valuing an instrument at its cost and thereafter applying a
constant amortization to maturity of any discount or premium, regardless of the
impact of fluctuating interest rates on the market value of the instrument.
During periods of declining interest rates, the daily yield on shares of the
Money Fund may be higher than that of a fund with identical investments
utilizing a method of valuation based upon market prices for its portfolio
instruments; the converse would apply in a period of rising interest rates.

     The valuation at amortized cost is in accordance with the provisions of
Rule 2a-7 under the Act. Pursuant to such rule, the Money Funds maintain a
dollar-weighted average portfolio maturity of 90 days or less and invests only
in securities of high quality (as defined by the Rule). The Money Funds also

purchase instruments which, at the time of investment, have remaining maturities
of no more than one year which maturities may extend to 397 days. The Money
Funds maintain procedures designed to stabilize, to the extent reasonably
possible, the price per share as computed for the purpose of sales and
redemptions at $1.00. Such procedures include review of the Money Funds'
portfolio holdings by the Adviser at such intervals as the Adviser deems
appropriate to determine whether and to what extent the net asset value of the
Money Funds calculated by using available market quotations or market
equivalents deviates from net asset value based on amortized cost. If such
deviation exceeds 1/2 of 1%, the Adviser will promptly consider what action, if
any, should be initiated. In the event the Adviser determines that such a
deviation may result in material dilution or other unfair results to new
investors or existing shareholders, they will consider corrective action which
might include (1) selling instruments prior to maturity to realize capital gains
or losses or to shorten average portfolio maturity, (2) withholding dividends of
net income on shares, or (3) establishing a net asset value per share using
available market quotations or equivalents. There can be no assurance, however,
that the Money Funds' net asset value per share will remain constant at $1.00.


                    DAILY DIVIDENDS, DISTRIBUTIONS AND TAXES

     Daily Dividend. The net investment income of the Money Funds is declared
daily as a dividend to holders of record, after giving effect to redemptions
received during the day, following the determination of net asset value as of
the close of business of regular sessions of the NYSE. Net investment income
consists of all accrued interest income on the Money Funds' portfolio assets
less the Money Funds' actual and accrued expenses applicable to that dividend
period. Realized gains and losses are reflected in net asset value and are not
included in net investment income.

     Because the net investment income of each Money Fund is declared as a
dividend each time the net investment income of the Fund is determined and is
expressed by an increase in



                                       21
<PAGE>


the number of shares held at a $1.00 price, the net asset value per share of
each Money Fund (i.e., the value of the net assets of the Fund divided by the
number of shares of the Money Fund outstanding) is expected to remain at $1.00
per share immediately after each such determination and dividend declaration,
unless (i) there are unusual or extended fluctuations in short-term interest
rates or other factors, such as unfavorable changes in the creditworthiness of
issuers affecting the value of securities in the Money Fund's portfolio, or (ii)
net income is a negative amount. Normally, each Money Fund will have a positive
net investment income at the time of each determination thereof. Net investment
income may be negative if an unexpected liability must be accrued or a loss
realized. If the net investment income of a Money Fund determined at any time is
a negative amount, the net asset value per share will be reduced below $1.00
unless one or more of the following steps are taken: the Adviser has the

authority (i) to reduce the number of shares in each shareholder's account, (ii)
to offset each shareholder's pro rata portion of negative net investment income
from the shareholder's accrued dividend account or from future dividends, or
(iii) to combine these methods in order to seek to maintain the net asset value
per share at $1.00. Each Money Fund may endeavor to restore the net asset value
per share to $1.00 by not declaring dividends from net investment income on
subsequent days until restoration, with the result that the net asset value per
share will increase to the extent of positive net investment income which is not
declared as a dividend.

     Should the Money Funds incur or anticipate any unusual or unexpected
significant expense or loss which would affect disproportionately the Money
Funds' income for a particular period, the Adviser would at that time consider
whether to adhere to the dividend policy described above or to revise it in
light of the then prevailing circumstances in order to ameliorate to the extent
possible the disproportionate effect of such expense, loss or depreciation on
then existing shareholders. Such expenses or losses may nevertheless result in a
shareholder's receiving no dividends for the period during which the shares are
held and in receiving upon redemption a price per share lower than that which
was paid.

     The Money Funds do not anticipate realizing any long-term capital gains.
Distributions of realized capital gains, if any, would normally be paid in
November or December. The Money Funds expect to follow the practice of
distributing any net realized capital gains to shareholders at least annually.
However, if any realized capital gains are retained by the Money Funds for
reinvestment and Federal income taxes are paid thereon by the Money Funds, the
Money Funds will elect to treat such capital gains as having been distributed to
shareholders; as a result, shareholders would be able to claim their share of
the taxes paid by the Money Funds on such gains as a credit against their
individual Federal income tax liability.

     There is no fixed dividend rate and there can be no assurance that a Money
Fund will pay any dividends or realize any gains. The amount of any dividend or
distribution paid by each Money Fund depends upon the realization by the Money
Fund of income and capital gains from that Money Fund's investments. All
dividends and distributions will be made to shareholders of a Money Fund solely
from assets of that Money Fund.



                                       22
<PAGE>


     Taxation of Distributions. For shareholders' Federal income tax purposes,
all distributions by the Money Funds out of interest income and net realized
short-term capital gains are treated as ordinary income, and distributions of
long-term capital gains, if any, are treated as long-term capital gains
irrespective of the length of time the shareholder held shares in the Money
Funds. Since the Money Funds derive nearly all of their gross income in the form
of interest income, and not dividends from domestic corporations, it is expected
that for corporate shareholders, none of the Money Funds' distributions will be
eligible for the dividends-received deduction under current law.


     For shareholders' Federal income tax purposes, distributions to
shareholders out of tax-exempt interest income earned by the Municipal Fund
generally are not subject to Federal income tax. However, distributions derived
from interest which is exempt from regular federal income tax may subject
corporate shareholders to or increase their liability under the AMT. A portion
of such distributions may constitute a tax preference item for individual
shareholders and may subject them to or increase their liability under the AMT.

     Shareholders of the Money Funds may be subject to state and local taxes on
distributions received from the Money Funds and on redemptions of the Money
Funds' shares. Under the laws of certain states, distributions of investment
company taxable income are taxable to shareholders as dividends, even though a
portion of such distributions may be derived from interest on U.S. Government
obligations which, if received directly by such shareholders, would be exempt
from state income tax.

     Shareholders will be advised annually as to the federal (and state, for the
Municipal Fund) tax status of dividends and capital gains distributions, if any,
made by each Money Fund for the preceding year.

   
     Tax Qualification of the Money Funds. Each Money Fund intends to qualify as
a regulated investment company under Subchapter M of the Internal Revenue Code
of 1986 (the "Code"), as amended, so that it will not be liable for federal
income taxes to the extent that its net taxable income and net capital gains are
distributed. Accordingly, each Money Fund must, among other things, (a) derive
at least 90% of its gross income from dividends, interest, payments with respect
to securities loans, gains from the sale or other disposition of stock or
securities or other foreign currencies, or other income (including but not
limited to gains from futures and forward contracts) derived with respect to its
business of investing in stock, securities or currencies; and (b) diversify
its holdings so that, at the end of each fiscal quarter, (i) at least 50% of the
market value of the Money Fund's assets is represented by cash, U.S. Government
securities and other securities, with such other securities limited, in respect
of any one issuer, to an amount not greater than 5% of the Fund's assets and 10%
of the outstanding voting securities of such issuer, and (ii) not more than 25%
of the value of its assets is invested in the securities of any one issuer
(other than U.S. Government securities). In addition, each Money Fund will be
subject to a nondeductible 4% excise tax on the excess, if any, of certain
required distribution amounts over the amounts actually distributed by that
Money Fund. To the extent possible, each Money Fund intends to make such
distributions as may be necessary to avoid this excise tax.
    



                                       23
<PAGE>


     Subchapter M of the Code also permits the character of tax-exempt interest
distributed by a regulated investment company to flow-through as tax-exempt
interest to its shareholders, provided that at least 50% of the value of its

assets at the end of each quarter of the taxable year is invested in state,
municipal and other obligations the interest on which is exempt under Section
103(a) of the Code. The Municipal Fund intends to satisfy this 50% requirement
in order to permit distributions of tax-exempt interest to be treated as such
for Federal income tax purposes in the hands of their shareholders.
Distributions to shareholders of tax-exempt interest earned by the Municipal
Fund for the taxable year are therefore not subject to regular Federal income
tax, although they may be subject to the individual and corporate alternative
minimum taxes described above. Discount from certain stripped tax-exempt
obligations or their coupons, however, may be taxable.
   
     Amendments to the code made in 1993 required that any market discount
recognized on a tax-exempt bond is taxable as ordinary income. This rule applies
for disposals of bonds purchased after April 30, 1993. A market discount bond 
is a bond acquired in the secondary market at a price below its redemption
value. Accordingly, gain on the disposition by a Money Fund of a tax-exempt 
obligation or any other market discount bond that is acquired for a price less 
than its principal amount will be treated as ordinary income (instead of 
capital gain) to the extent of accrued market discount.
    
     Since the Money Funds are not treated as a single entity for Federal income
tax purposes, the performance of one Money Fund will have no effect on the
income tax liability of shareholders of another Money Fund.

     Dividend or capital gains distributions with respect to shares of any Money
Fund held by a tax-deferred or qualified retirement plan, such as an IRA, Keogh
Plan or corporate pension or profit sharing plan, will not be taxable to the
plan. Distributions from such plans will be taxable to individual participants
under applicable tax rules without regard to the character of the income earned
by the qualified plan.

     Taxation of Investor's Indebtedness. It is unlikely that interest on
indebtedness incurred by shareholders to purchase or carry shares of the Money
Funds will be deductible for Federal income tax purposes. Under rules of the
Internal Revenue Service for determining when borrowed funds are used for
purchasing or carrying particular assets, shares may be considered to have been
purchased or carried with borrowed funds even though those funds are not
directly linked to the shares. Further, persons who are "substantial users" (or
related persons) of facilities financed by private activity bonds (within the
meaning of Section 147(a) of the Code) should consult their tax advisers before
purchasing shares of the Municipal Fund. The Municipal Fund has not undertaken
any investigation as to the users of the facilities financed by bonds in its
portfolio.



                                       24
<PAGE>


     Tax Withholding. Each Money Fund is required to withhold and remit to the
U.S. Treasury 31% of the dividends or the proceeds of any redemptions or
exchanges of shares with respect to any shareholder who fails to furnish the
Money Funds with a correct taxpayer identification number, who under-reports


dividend or interest income, or who fails to certify to the Money Funds that he
or she is not subject to such withholding. An individual's tax identification
number is his or her social security number.

     Tax Legislation. Tax legislation in recent years has included several
provisions that may affect the supply of, and the demand for, tax-exempt bonds,
as well as the tax-exempt nature of interest paid thereon. It is not possible to
predict with certainty the effect of these recent tax law changes upon the
tax-exempt bond market, including the availability of obligations appropriate
for investment, nor is it possible to predict any additional restrictions that
may be enacted in the future. The Municipal Fund will monitor developments in
this area and consider whether changes in its objectives or policies are
desirable.

     General. The foregoing discussion of U.S. federal income tax law relates
solely to the application of that law to U.S. persons, i.e., U.S. citizens and
residents and U.S. corporations, partnerships, trusts and estates. Each
shareholder who is not a U.S. person should consider the U.S. and foreign tax
consequences of ownership of shares of the Money Funds, including the
possibility that such a shareholder may be subject to a U.S. withholding tax at
a rate of 30% (or at a lower rate under an applicable income tax treaty) on
amounts constituting ordinary income received by the shareholder, where such
amounts are treated as income from U.S. sources under the Code.

     Shareholders should consult their tax advisers about the application of the
provisions of tax law described in this combined Statement of Additional
Information in light of their particular tax situations.

     The foregoing discussion is a general summary of certain current Federal
income tax laws regarding the Money Funds. The discussion does not purport to
deal with all of the Federal income tax consequences applicable to the Money
Funds, or to all categories of investors, some of whom may be subject to special
rules. Each prospective shareholder should consult with his or her own
professional tax adviser regarding federal, state and local tax consequences of
ownership of shares of the Money Funds.


                             PORTFOLIO TRANSACTIONS

     Subject to the general supervision of the Board of Trustees of the Money
Funds, the Adviser is responsible for the investment decisions and the placing
of orders for portfolio transactions for the Money Funds. Portfolio transactions
for the Money Funds are normally effected by brokers.

     The Money Funds have no obligation to enter into transactions in portfolio
securities with any broker, dealer, issuer, underwriter or other entity. In
general, the securities the 



                                       25
<PAGE>



Money Funds will purchase are in over-the-counter markets in which purchases and
sales are affected directly with a dealer acting as principal. The dealers
impose a mark-up on their cost which is usually not disclosed to the Money
Funds. Therefore, the Money Funds will generally make purchases based
exclusively on best price, although execution may be a factor in certain
circumstances. In placing orders, it is the policy of the Money Funds to obtain
the best price and execution for its transactions.


                       INVESTMENT PERFORMANCE INFORMATION

     The Money Funds may furnish data about its investment performance in
advertisements, sales literature and reports to shareholders. From time to time
evaluations of performance are made by independent sources that may be used in
advertisements concerning each Money Fund. These sources include Lipper
Analytical Services, Weisenberger Investment Company Service, Barron's, Business
Week, Kiplinger's Personal Finance, Financial World, Forbes, Fortune, Money,
Personal Investor, Sylvia Porter's Personal Finance, Bank Rate Monitor,
Morningstar and The Wall Street Journal.

     These performance figures may be calculated in the following manner:

Yield

   
     Yield is the net annualized yield based on a specified 7 calendar days
calculated at simple interest rates. Yield is calculated by determining the net
change exclusive of capital changes, in the value of a hypothetical pre-existing
account having a balance of one share at the beginning of the period, and
dividing the difference by the value of the account at the beginning of the base
period to obtain the base period return. The yield is annualized by multiplying
the base period return by 365/7. The yield figure is stated to the nearest
hundredth of one percent. The yield quotation based on the 7 days ended October
31, 1997 was 2.82% and 4.71% for the Municipal Fund and Government Fund,
respectively.
    


                                       26
<PAGE>


Effective Yield

     Effective yield is the net annualized yield for a specified 7 calendar days
assuming a reinvestment of the income or compounding. Effective yield is
calculated by the same method as yield except the effective yield figure is
compounded by adding 1, raising the sum to a power equal to 365 divided by 7,
and subtracting 1 from the result, according to the following formula:

     Effective yield = [(Base Period Return + 1)^(365/7)] - 1.

   
     The effective yield quotation based on the 7 days ended October 31, 1997

was 2.86% and 4.82% for the Municipal Fund and Government Fund, respectively.
    

Tax-Equivalent Yield

     Tax-equivalent yield is the net annualized taxable yield needed to produce
a specified tax-exempt yield at a given tax rate based on a specified 30-day
period assuming a reinvestment of all dividends paid during such period.
Tax-equivalent yield is calculated by dividing that portion of each Money Fund's
yield (as computed in the yield description above) which is tax-exempt by one
minus a stated income tax rate and adding the product to that portion, if any,
of the yield of the Money Fund that is not tax-exempt.

     The following chart will illustrate the effects of tax-exempt income versus
taxable income.

     Based on 1997 Federal tax rates, a married couple filing a joint return
with two exemptions and taxable income of $50,000 would have to earn a
tax-equivalent yield of 6.94% in order to match a tax-free yield of 5%.
    
     There is no guarantee that a fund will achieve a specific yield. While most
of the income distributed to the shareholders of each Money Fund will be exempt
from Federal income taxes, distributions may be subject to state and local
taxes.

     Quotations of total return will reflect only the performance of an
investment in any Money Fund during the particular time period shown. Each Money
Fund's total return and current yield may vary from time to time depending on
market conditions, the compositions of its portfolio

- ----------
     3    These illustrations assume the Federal alternative minimum tax is not
          applicable, that an individual is not a "head of household" and claims
          one exemption and that taxpayers filing a joint return claim two
          exemptions. Note also that these Federal income tax brackets and rates
          do not take into account the effects of (i) a reduction in the
          deductibility of itemized deductions for taxpayers whose Federal
          adjusted gross income exceeds $121,200 ($60,600 in the case of a
          married individual filing a separate return), or of (ii) the gradual
          phaseout of the personal exemption amount for taxpayers whose federal
          adjusted gross income exceeds $121,200 (for single individuals). The
          effective Federal tax rates and equivalent yields for such taxpayers
          would be higher than those shown above.

and operating expenses. These factors and possible differences in the methods
used in calculating yield should be considered when comparing each Money Fund's
current yield to yields published for other investment companies and other
investment vehicles. Total return and yield should also be considered relative
to change in the value of each Money Fund's shares and the risks associated with
each Money Fund's investment objectives, policies and risk considerations.

     In connection with communicating its yield, effective yield or
tax-equivalent yield to current or prospective shareholders, each Money Fund may
also compare these figures to the performance of other mutual funds tracked by

mutual fund rating services or to other unmanaged indices which may assume
reinvestment of dividends but generally do not reflect deductions for
administrative and management costs.

                               GENERAL INFORMATION

Organization and Capitalization

     Winthrop Opportunity Funds was formed on May 31, 1995 as a "business trust"
under the laws of the state of Delaware.

     The Agreement and Declaration of Trust provides that no Trustee, officer,
employee or agent of the Opportunity Funds is liable to the Funds or to a
shareholder, nor is any Trustee, officer, employee or agent liable to any third
person in connection with the affairs of the Funds, except as such liability may
arise from his or its own bad faith, willful misfeasance, gross negligence or
reckless disregard of his or her duties. It also provides that all third parties
shall look solely to the property of the appropriate Opportunity Fund for
satisfaction of claims arising in connection with the affairs of an Opportunity
Fund. With the exceptions stated, the Agreement and Declaration of Trust permits
the Trustees to provide for the indemnification of Trustees, officers, employees
or agents of the Opportunity Funds against all liability in connection with the
affairs of the Opportunity Funds.

     All shares of the Opportunity Funds when duly issued will be fully paid and
non-assessable. The Trustees are authorized to re-classify and issue any
unissued shares to any number of additional series without shareholder approval.

Accordingly, the Trustees in the future,



                                       30
<PAGE>


for reasons such as the desire to establish one or more additional Opportunity
Funds with different investment objectives, policies, risk considerations or
restrictions, may create additional series or classes of shares. Any issuance of
shares of such additional series would be governed by the Act and the laws of
the State of Delaware.

                                   APPENDIX A

                               SECURITIES RATINGS



     The following is a description of the ratings given by S&P and Moody's to
U.S. municipal and government securities in which the Money Funds are permitted
to invest in accordance with Rule 2a-7 of the Act.

Rating of Municipal Obligations

     S&P:

     The two highest ratings of S&P for municipal bonds are AAA (Prime) and AA
(High-grade). Bonds rated AAA have the highest rating assigned by S&P to a
municipal obligation. Capacity to pay interest and repay principal is extremely
strong. Bonds rated AA have a very strong capacity to pay interest and repay
principal and differ from the highest rated issues only in a small degree. The
rating may be modified by the addition of a plus (+) or a minus (-) to show
relative standing within the category.

     S&P top ratings for municipal notes are SP-1 and SP-2. The designation SP-1
indicates a very strong capacity to pay principal and interest. A "+" is added
for those issues determined to possess overwhelming safety characteristics. An
"SP-2" designation indicates a satisfactory capacity to pay principal and
interest.

     Moody's:

     The two highest ratings of Moody's for municipal bonds are Aaa and Aa.
Bonds rated Aaa are judged by Moody's to be of the best quality. Bonds rated Aa
are judged to be of high quality by all standards. Together with the Aaa group,
they comprise what are generally known as high-grade bonds. Moody's states that
Aa bonds are rated lower than the best bonds because margins of protection or
other elements make long-term risks appear somewhat larger than for Aaa
municipal bonds. Moody's rates a bond in the Aa category as Aa1 if Moody's
believes the bond possesses strong attributes within the category.

     Moody's ratings for municipal notes and other short-term loans are
designated Moody's Investment Grade (MIG) and Variable Rate Demand Obligation
Moody's Investment Grade (VMIG). This distinction is in recognition of the
differences between short-term and long-term credit risk. Loans bearing the
designation MIG1/VMIG1 are of the best quality, enjoying strong protection by
establishing cash flows of funds for their servicing or by established and
broad-based access to the market for refinancing, or both. Loans bearing the
designation MIG2/VMIG2 are of high quality with margins of protection ample
although not as large as in the preceding group.



                                       32
<PAGE>


Commercial Paper Ratings

     S&P:


     Commercial paper rated A-1 or better by S&P has the following
characteristics: liquidity ratios are adequate to meet cash requirements;
long-term senior debt is rated "A" or better, although in some cases "BBB"
credits may be allowed; the issuer has access to at least two additional
channels of borrowing; and basic earnings and cash flow have an upward trend
with allowance made for unusual circumstances. Typically, the issuer's industry
is well established and the issuer has a strong position within the industry.
The reliability and quality of management are unquestioned.

     Moody's:

     The rating Prime-1 is the highest commercial paper rating assigned by
Moody's. Among the factors considered by Moody's in assigning ratings are the
following: (1) evaluation of the management of the issuer; (2) economic
evaluation of the issuer's industry or industries and an appraisal of
speculative-type risks which may be inherent in certain areas; (3) evaluation of
the issuer's products in relation to competition and customer acceptance; (4)
liquidity; (5) amount and quality of long-term debt; (6) trend earnings over a
period of ten years; (7) financial strength of a parent company and the
relationship which exists with the issuer; and (8) recognition by the management
of obligations which may be present or may arise as a result of public interest
questions and preparations to meet such obligations.

                                   APPENDIX B

                      DESCRIPTIONS OF MUNICIPAL SECURITIES


     Municipal Notes generally are used to provide for short-term capital needs
and usually have maturities of one year or less. They include the following:

   
1.   Project Notes, which carry a U.S. Government guarantee, are issued by
     public bodies (called "local issuing agencies") created under the laws of a
     state, territory, or U.S. possession. They have maturities that range up to
     one year from the date of issuance. Project Notes are backed by an
     agreement between the local issuing agency and the Federal Department of
     Housing and Urban Development. These Notes provide financing for a wide
     range of financial assistance programs for housing, redevelopment, and
     related needs (such as low-income housing programs and renewal programs).

2.   Tax Anticipation Notes are issued to finance working capital needs of
     municipalities. Generally, they are issued in anticipation of various
     seasonal tax revenues, such as income, sales, use and business taxes, and
     are payable from those specific future taxes.

3.   Revenue Anticipation Notes are issued in expectation of receipt of other
     types of revenues, such as Federal revenues available under the Federal
     Revenue Sharing Programs.


4.   Bond Anticipation Notes are issued to provide interim financing until
     long-term financing can be arranged. In most cases, the long-term bonds
     then provide the money for the repayment of the Notes.

5.   Construction Loan Notes are sold to provide construction financing.
     After successful completion and acceptance, many projects receive permanent
     financing through the Federal Housing Administration under the Federal
     National Mortgage Association or the Government National Mortgage
     Association.

6.   Tax-Exempt Commercial Paper is a short-term obligation with a stated
     maturity of 365 days or less. It is issued by agencies of state and local
     governments to finance seasonal working capital needs or as short-term
     financing in anticipation of longer term financing.
    



                                       34
<PAGE>


     Municipal Bonds, which meet longer term capital needs and generally have
maturities of more than one year when issued, have three principal
classifications:

   
7.   General Obligation Bonds are issued by such entities as states, counties,
     cities, towns, and regional districts. The proceeds of these obligations
     are used to fund a wide range of public projects, including construction or
     improvement of schools, highways, and roads, and water and sewer systems.
     The basic security behind General Obligation bonds is the issuer's pledge
     of its full faith and credit and taxing power for the payment of principal
     and interest. The taxes that can be levied for the payment of debt service
     may be limited or unlimited as to the rate or amount of special
     assessments.

8.   Revenue Bonds generally are accrued by the net revenues derived from a
     particular facility, group of facilities, or, in some cases, the proceeds
     of a special excise or other specific revenue source. Revenue Bonds are
     issued to finance a wide variety of capital projects including electric,
     gas, water and sewer systems; highways, bridges, and tunnels; port and
     airport facilities; colleges and universities; and hospitals. Many of these
     Bonds provide additional security in the form of a debt service reserve
     fund to be used to make principal and interest payments. Housing
     authorities have a wide range of security, including partially or fully
     insured mortgages, and/or the net revenues from housing or other public
     projects. Some authorities provide further security in the form of a
     state's ability (without obligation) to make up deficiencies in the debt
     service reserve fund.

9.   Industrial Development Bonds are considered municipal bonds if the interest
     paid thereon is exempt from Federal income tax and are issued by or on

     behalf of public authorities to raise money to finance various privately
     operated facilities for business and manufacturing, housing, sports, and
     pollution control. These Bonds are also used to finance public facilities
     such as airports, mass transit system, ports, and parking. The payment of
     the principal and interest on such Bonds is dependent solely on the ability
     or the facility's user to meet its financial obligations and the pledge, if
     any, of real and personal property as security for such payment.

                      INVESTMENT POLICIES AND RESTRICTIONS

     The following investment policies and restrictions supplement and should be
read in conjunction with the information set forth under the heading "Investment
Objectives and Policies" in the International Funds' Prospectus. Except as noted
in the Prospectus, each International Fund's investment policies are not
fundamental and may be changed by the Trustees of the Funds without shareholder
approval; however, shareholders will be notified prior to significant change in
such policies. Each International Fund's fundamental investment restrictions may
not be changed without shareholder approval as defined in "Fundamental
Investment Restrictions" in this Statement of Additional Information.

     It is the policy of the Developing Markets Fund to seek long-term growth of
capital by investing primarily in common stocks and other equity securities from
developing countries; it is the policy of the International Equity Fund to seek
long-term growth of capital by investing primarily in common stocks and other
equity securities from established markets outside the United States. In
addition, each International Fund may invest in any of the securities described
below.

     Depositary Receipts. The International Funds may purchase sponsored or
unsponsored ADRs, EDRs and GDRs (collectively, "Depositary Receipts"). ADRs are
American Depositary Receipts typically issued by a U.S. bank or trust company
which evidence ownership of underlying securities issued by a foreign
corporation. EDRs and GDRs are Depositary Receipts typically issued by foreign
banks or trust companies, although they also may be issued by U.S. banks or
trust companies, and evidence ownership of underlying securities issued by
either a foreign or a United States corporation. Generally, Depositary Receipts
in registered form are designed for use in the U.S. securities market and
Depositary Receipts in bearer form are designed for use in securities markets
outside the United States. Depositary Receipts may not necessarily be
denominated in the same currency as the underlying securities into which they
may be converted. Depositary Receipts may be issued pursuant to sponsored or
unsponsored programs. In sponsored programs, an issuer has made arrangements to
have its securities traded in the form of Depositary Receipts. In unsponsored
programs, the issuer may not be directly involved in the creation of the
program. Although regulatory requirements with respect to sponsored and
unsponsored programs are generally similar, in some cases it may be easier to
obtain financial information from an issuer that has participated in the
creation of a sponsored program. Accordingly, there may be less information
available regarding issuers of securities underlying unsponsored programs and
there may not be a correlation between such information and the market value of
the Depositary Receipts. For purposes of each International Fund's investment
policies, an International Fund's investments in Depositary Receipts will be
deemed to be investments in the underlying securities.


                                       2

     Convertible Securities. A convertible security is a bond or preferred stock
which may be converted at a stated price within a specified period of time into
a certain quantity of the common stock of the same or different issuer.
Convertible securities are senior to common stocks in a corporation's capital
structure, but are usually subordinated to similar nonconvertible securities.
While providing a fixed income stream (generally higher in yield than the income
stream from common stocks but lower than that afforded by a similar
nonconvertible fixed income security), a convertible security also affords an
investor the opportunity, through its conversion feature, to participate in the
capital appreciation dependent upon a market price advance in the underlying
common stock. Each International Fund may invest up to 25% of its assets in
foreign convertible securities. Wood, Struthers & Winthrop Management Corp. (the
"Adviser") and AXA Asset Management Partenaires (the "Subadviser") currently do
not intend to invest over 5% of each International Fund's assets in convertible
securities rated below investment grade.

     The market value of a convertible security is at least the higher of its
"investment value" (i.e., its value as a fixed-income security) or its
"conversion value" (i.e., its value when converted into its underlying common
stock). As a fixed-income security, a convertible security tends to increase in
market value when interest rates decline and tends to decrease in value when
interest rates rise. However, the price of a convertible security is also
influenced by the market value of the underlying security. The price of a
convertible security tends to increase as the market value of the underlying
stock rises, whereas it tends to decrease as the market value of the underlying
stock declines. While no securities investment is without some risk, investments
in convertible securities generally entail less risk than investments in the
common stock of the same issuer.

     Nonconvertible Fixed Income Securities. Each International Fund may invest
up to 35% of its total assets in investment grade fixed income securities.
Investment grade obligations are those obligations rated BBB or better by
Standard and Poor's Ratings Group ("S&P") or Baa or better by Moody's Investor
Service ("Moody's") in the case of long-term obligations and equivalently rated
obligations in the case of short-term obligations, or unrated instruments
believed by the Adviser or Subadviser to be of comparable quality to such rated
instruments. Securities rated BBB by S&P are regarded by S&P as having an
adequate capacity to pay interest and repay principal. Whereas such securities
normally exhibit adequate protection parameters, adverse economic conditions or
changing circumstances are more likely, in the opinion of S&P, to lead to a
weakened capacity to pay interest and repay principal for debt in this category
than in higher rated categories. Securities rated Baa by Moody's are considered
by Moody's to be medium grade obligations; they are neither highly protected nor
poorly secured; interest payments and principal security appear to be adequate
for the present but certain protective elements may be lacking or may be
characteristically unreliable over any great length of time; in the opinion of
Moody's, they lack outstanding investment characteristics and in fact have
speculative characteristics as well. Fixed income securities in which the
International Funds may invest include asset and mortgage backed securities.
Prepayments of principal may be made at any time on the obligations underlying
asset and mortgage backed securities and are passed on to the holders of the

assets and mortgage backed securities. As a result, if an International Fund
purchases such a security at a premium, faster than expected prepayments will
reduce and slower than expected prepayments will increase yield to maturity.
Conversely, if an International Fund purchases these securities at a discount,
faster than expected prepayments will increase, while 



                                       3
<PAGE>


slower than expected prepayments will reduce, yield to maturity. For a more
complete description of Moody's and S&P's ratings, see the Appendix to this
Statement of Additional Information. The foregoing investment grade limitation
applies only at the time of initial investment and an International Fund may
determine to retain in its portfolio securities the issuers of which have had
their credit characteristics downgraded.

     Options. The International Funds may purchase and sell call and put
options. A call option gives the purchaser, in exchange for a premium paid, the
right for a specified period of time to purchase the securities or currency
subject to the option at a specified price (the exercise price or strike price).
The writer, or seller, of a call option, in return for the premium, has the
obligation, upon exercise of the option, to deliver, depending upon the terms of
the option contract, the underlying securities or a specified amount of cash to
the purchaser upon receipt of the exercise price. When an International Fund
writes a call option, that Fund gives up the potential for gain on the
underlying securities or currency in excess of the exercise price of the option
during the period that the option is open.

     A put option gives the purchaser, in return for a premium, the right, for a
specified period of time, to sell securities or currency subject to the option
to the writer of the put at the specified exercise price. The writer of the put
option, in return for the premium, has the obligation, upon exercise of the
option, to acquire the securities or currency underlying the option at the
exercise price. An International Fund that sells a put option might, therefore,
be obligated to purchase the underlying securities or currency for more than
their current market price.

     If an International Fund desires to sell a particular security from its
portfolio on which it has written an option, the International Fund will seek to
effect a closing purchase transaction prior to or concurrently with the sale of
the security. A closing purchase transaction is a transaction in which an
investor who is obligated as a writer of an option terminates his obligation by
purchasing an option of the same series as the option previously written. (Such
a purchase does not result in the ownership of an option). An International Fund
may enter into a closing purchase transaction to realize a profit on a
previously written option or to enable the International Fund to write another
option on the underlying security with either a different exercise price or
expiration date or both. An International Fund realizes a profit or loss from a
closing purchase transaction if the cost of the transaction is less or more,
respectively, than the premium received from the writing of the option.


     The International Funds will write only fully "covered" options. An option
is fully covered if at all times during the option period, the Fund writing the
option owns either (i) the underlying securities, or securities convertible into
or carrying rights to acquire the optioned securities at no additional cost, or
(ii) an offsetting call option on the same securities at the same or a lower
price.

     An International Fund may not write a call option if, as a result thereof,
the aggregate of such International Fund's portfolio securities subject to
outstanding call options (valued at the lower of the option price or market
value of such securities) would exceed 10% of its total assets. The
International Funds may also purchase and sell financial futures contracts and
options 



                                       4
<PAGE>


thereon for hedging and risk management purposes and to enhance gains as
permitted by the Commodity Futures Trading Commission (the "CFTC").

     The International Funds may also purchase and sell securities index
options. Securities index options are similar to options on specific securities.
However, because options on securities indices do not involve the delivery of an
underlying security, the option represents the holder's right to obtain from the
writer in cash a fixed multiple of the amount by which the exercise price
exceeds (in the case of a put) or is less than (in the case of a call) the
closing value of the underlying securities index on the exercise date. When an
International Fund writes an option on a securities index, it will establish a
segregated account with its custodian in which it will deposit cash or high
quality short-term obligations or a combination of both with a value equal to or
greater than the market value of the option and will maintain the account while
the option is open.

     Each International Fund's successful use of options and financial futures
depends on the ability of the Adviser and Subadviser to predict the direction of
the market and is subject to various additional risks. The investment techniques
and skills required to use options and futures successfully are different from
those required to select International securities for investment. The ability of
an International Fund to close out an option or futures position depends on a
liquid secondary market. There is no assurance that liquid secondary markets
will exist for any particular option or futures contract at any particular time.
The inability to close options and futures positions also could have an adverse
impact on each International Fund's ability to effectively hedge its portfolio.
There is also the risk of loss by the International Funds of margin deposits or
collateral in the event of bankruptcy of a broker with whom the International
Funds have an open position in an option, a futures contract or related option.

     To the extent that puts, calls, straddles and similar investment strategies
involve instruments regulated by the CFTC, each International Fund is limited to
an investment not in excess of 5% of its total assets, except that each
International Fund may purchase and sell such instruments, without limitation,

for bona fide hedging purposes.

     Forward Foreign Currency Exchange Contracts. A forward contract on foreign
currency is an obligation to purchase or sell a specific currency at a future
date, which may be any fixed number of days agreed upon by the parties from the
date of the contract at a price set on the date of the contract.

     The International Funds will generally enter into forward contracts only
under two circumstances. First, when an International Fund enters into a
contract for the purchase or sale of a security denominated in a foreign
currency, it may desire to "lock in" the U.S. dollar price of the security in
relation to another currency by entering into a forward contract to buy the
amount of foreign currency needed to settle the transaction. Second, when the
Adviser or Subadviser believes that the currency of a particular foreign country
may suffer or enjoy a substantial movement against another currency, it may
enter into a forward contract to sell or buy the former foreign currency (or
another currency which acts as a proxy for that currency) approximating the
value of some or all of the International Fund's portfolio securities
denominated in such foreign 



                                       5
<PAGE>


currency. This second investment practice is generally referred to as
"cross-hedging." Although forward contracts will be used primarily to protect
the International Funds from adverse currency movements, they also involve the
risk that anticipated currency movements will not be accurately predicted.

     Futures and Options Thereon. The International Funds may purchase and sell
financial futures contracts and options thereon which are traded on a
commodities exchange or board of trade for certain hedging, return enhancement
and risk management purposes in accordance with regulations of the CFTC. These
futures contracts and related options will be on financial indices and foreign
currencies or groups of foreign currencies. A financial futures contract is an
agreement to purchase or sell an agreed amount of securities or currencies at a
set price for delivery in the future.

     Repurchase Agreements. The International Funds may enter into "repurchase
agreements" with member banks of the Federal Reserve System, "primary dealers"
(as designated by the Federal Reserve Bank of New York) in such securities or
with any domestic or foreign broker/dealer which is recognized as a reporting
government securities dealer. Repurchase agreements permit an International Fund
to keep all of its assets at work while retaining "overnight" flexibility in
pursuit of investments of a longer-term nature. The International Funds require
continual maintenance of collateral with the Custodian in an amount equal to, or
in excess of, the market value of the securities which are the subject of a
repurchase agreement. In the event a vendor defaults on its repurchase
obligation, the International Fund might suffer a loss to the extent that the
proceeds from the sale of the collateral were less than the repurchase price. If
the vendor becomes the subject of bankruptcy proceedings, the International Fund
might be delayed in selling the collateral.


     Reverse Repurchase Agreements. The International Funds may also enter into
reverse repurchase agreements. Under a reverse repurchase agreement an
International Fund would sell securities and agree to repurchase them at a
mutually agreed upon date and price. At the time an International Fund enters
into a reverse repurchase agreement, it would establish and maintain with an
approved custodian a segregated account containing liquid high-grade securities
having a value not less than the repurchase price. Reverse repurchase agreements
involve the risk that the market value of the securities subject to such
agreement could decline below the repurchase price to be paid by an
International Fund for such securities. In the event the buyer of securities
under a reverse repurchase agreement filed for bankruptcy or became insolvent,
such buyer or receiver would receive an extension of time to determine whether
to enforce an International Fund's obligations to repurchase the securities and
an International Fund's use of the proceeds of the reverse repurchase could
effectively be restricted pending such decision. Reverse repurchase agreements
create leverage, a speculative factor, but are not considered senior securities
by the International Funds or the Securities and Exchange Commission ("SEC") to
the extent liquid high-grade debt securities are segregated in an amount at
least equal to the amount of the liability.

     Illiquid Investments. Each International Fund may invest up to 15% of its
assets in illiquid investments. Under the supervision of the Trustees, the
Adviser and Subadviser determine the liquidity of an International Fund's
investments. The absence of a trading market can make it difficult to ascertain
a market value for illiquid investments. Disposing of illiquid investments may
involve time-consuming negotiation and legal expenses, and it may be difficult
or impossible for an International Fund to sell them promptly at an acceptable
price. The staff of the SEC currently takes the position that OTC options
purchased by an International Fund, and portfolio securities "covering" the
amount of that International Fund's obligation pursuant to an OTC option sold by
it (the cost of the sell-back plus the in-the-money amount, if any) are
illiquid, and are subject to such International Fund's limitations on
investments in illiquid securities.

     Borrowing. Each International Fund may borrow up to one-third of the value
of its total assets from banks to increase its holdings of portfolio securities
or for other purposes. Under the Investment Company Act of 1940, as amended (the
"1940 Act"), each International Fund is required to maintain continuous asset
coverage of 300% with respect to such borrowings. Leveraging by means of
borrowing may exaggerate the effect of any increase or decrease in the value of
portfolio securities on an International Fund's net asset value, and money
borrowed will be subject to interest and other costs (which may include
commitment fees and/or the cost of maintaining minimum average balances) which
may or may not exceed the income received from the securities purchased with
borrowed funds. The Adviser and Subadviser do not currently intend to engage in
borrowing transactions.

     Securities Lending. The International Funds may seek to receive or increase

income by lending their respective portfolio securities. Under present
regulatory policies, such loans may be made to member firms of the New York
Stock Exchange and are required to be secured continuously by collateral held by
the Custodian consisting of cash, cash equivalents or U.S. Government Securities
maintained in an amount at least equal to the market value of the securities
loaned. Accordingly, the International Funds will continuously secure the
lending of portfolio securities by collateral held by the Custodian consisting
of cash, cash equivalents or U.S. Government Securities maintained in an amount
at least equal to the market value of the securities loaned. The International
Funds have the right to call such a loan and obtain the securities loaned at any
time on five days notice. Cash collateral may be invested in fixed income
securities rated at least A or better by S&P or Moody's. As is the case with any
extension of credit, loans of portfolio securities involve special risks in the
event that the borrower should be unable to repay the loan, including delays or
inability to recover the loaned securities or foreclose against the collateral.
The aggregate value of securities loaned by an International Fund may not exceed
25% of the value of its net assets.

     When Issued, Delayed Delivery Securities and Forward Commitments. The
International Funds may, to the extent consistent with their other investment
policies and restrictions, enter into forward commitments for the purchase or
sale of securities, including on a "when issued" or "delayed delivery" basis in
excess of customary settlement periods for the type of security involved. In
some cases, a forward commitment may be conditioned upon the occurrence of a



                                       7
<PAGE>


subsequent event, such as approval and consummation of a merger, corporate
reorganization or debt restructuring, i.e., a when, as and if issued security.

     When such transactions are negotiated, the price is fixed at the time of
the commitment, with payment and delivery taking place in the future, generally
a month or more after the date of the commitment. While an International Fund
will only enter into a forward commitment with the intention of actually
acquiring the security, such International Fund may sell the security before the
settlement date if it is deemed advisable.

     Securities purchased under a forward commitment are subject to market
fluctuation, and no interest (or dividends) accrues to an International Fund
prior to the settlement date. Each International Fund will segregate with its
Custodian cash or liquid high-grade securities in an aggregate amount at least
equal to the amount of their respective outstanding forward commitments.

     Privatization. The governments in some countries have been engaged in
programs of selling part or all of their stakes in government owned or
controlled enterprises ("privatization"). The Adviser and Subadviser believe
that privatization may offer opportunities for significant capital appreciation
and intend to invest assets of the International Funds in privatization in
appropriate circumstances. In certain countries, the ability of foreign entities
such as the International Funds to participate in privatization may be limited

by local law and/or the terms on which the International Funds may be permitted
to participate may be less advantageous than those afforded local investors.
There can be no assurance that certain governments will continue to sell
companies currently owned or controlled by them or that privatization programs
will be successful.

     Investment Companies. Certain markets are closed in whole or in part to
International investments by foreigners. The International Funds may be able to
invest in such markets solely or primarily through governmentally authorized
investment vehicles or companies. Pursuant to the 1940 Act, each International
Fund generally may invest up to 10% of its total assets in the aggregate in
shares of other investment companies and up to 5% of its total assets in any one
investment company as long as each investment does not represent more than 3% of
the outstanding voting stock of the acquired investment company at the time of
investment. Investment in other investment companies may involve the payment of
substantial premiums above the value of such investment companies' portfolio
securities, and is subject to limitations under the 1940 Act and market
availability. The International Funds do not intend to invest in such investment
companies unless, in the judgment of the Adviser and Subadviser, the potential
benefits of such investment justify the payment of any applicable premium or
sales charge. As a shareholder in an investment company, an International Fund
would bear its ratable share of that investment company's expenses, including
its advisory and administration fees. At the same time, an International Fund
would continue to pay its own management fees and other expenses.

Fundamental Investment Restrictions

     The following fundamental investment restrictions are applicable to each of
the International Funds and may not be changed with respect to an International
Fund without the approval of a majority of the shareholders of that
International Fund, which means the affirmative vote of the holders of (a) 67%
or more of the shares of that International Fund represented at a meeting at
which more than 50% of the outstanding shares of the International Fund are
represented or (b) more than 50% of the outstanding shares of that International
Fund, whichever is less. Except as set forth in the Prospectus, all other
investment policies or practices are considered by each International Fund not
to be fundamental and accordingly may be changed without shareholder approval.
If a percentage restriction is adhered to at the time of investment, a later
increase or decrease in percentage resulting from a change in values or assets
will not constitute a violation of such restriction.

     Briefly, these restrictions provide that an International Fund may not:

          (1) purchase the securities of any one issuer, other than the United
     States Government, or any of its agencies or instrumentalities, if
     immediately after such purchase more than 5% of the value of its total
     assets would be invested in such issuer or the International Fund would own
     more than 10% of the outstanding voting securities of such issuer, except

     that up to 25% of the value of the International Fund's total assets may be
     invested without regard to such 5% and 10% limitations;

          (2) invest 25% or more of the value of its total assets in any one
     industry, provided that, for purposes of this policy, consumer finance
     companies, industrial finance companies and gas, electric, water and
     telephone utility companies are each considered to be separate industries;

          (3) issue senior securities (including borrowing money, including on
     margin if margin securities are owned and enter into reverse repurchase
     agreements) in excess of 33 1/3% of its total assets (including the amount
     of senior securities issued but excluding any liabilities and indebtedness
     not constituting senior securities) except that the International Fund may
     borrow up to an additional 5% of its total assets for temporary purposes;
     or pledge its assets other than to secure such issuances or in connection
     with hedging transactions, short sales, when-issued and forward commitment
     transactions and similar investment strategies. The International Fund's
     obligations under swaps are not treated as senior securities;

          (4) make loans of money or property to any person, except through
     loans of portfolio securities, the purchase of fixed income securities
     consistent with the International Fund's investment objective and policies
     or the acquisition of securities subject to repurchase agreements;



                                       9
<PAGE>


          (5) underwrite the securities of other issuers, except to the extent
     that in connection with the disposition of portfolio securities the
     International Fund may be deemed to be an underwriter:

          (6) purchase real estate or interests therein;

          (7) purchase or sell commodities or commodities contracts except for
     purposes, and only to the extent, permitted by applicable law without the
     International Fund becoming subject to registration with the CFTC as a
     commodity pool;

          (8) make any short sale of securities except in conformity with
     applicable laws, rules and regulations and unless, giving effect to such
     sale, the market value of all securities sold short does not exceed 25% of
     the value of the International Fund's total assets and the International
     Fund's aggregate short sales of a particular class of securities does not
     exceed 25% of the then outstanding securities of that class; or

          (9) invest in oil, gas or other mineral leases.

Adviser



                                       11
<PAGE>


     The Adviser, a Delaware corporation with principal offices at 277 Park
Avenue, New York, New York 10172, has been retained under an Investment Advisory
Agreement as the International Funds' investment adviser (see "Management" in
the Prospectus). The Adviser was established in 1871 as a private concern to
manage money for the Winthrop family of Boston. From these origins, the Adviser
has grown to serve a select group of individual and institutional investors.


   
     The Adviser is (since 1977) a wholly-owned subsidiary of Donaldson, Lufkin
& Jenrette Securities Corporation ("DLJ Securities"), the distributor of the
International Fund's shares, which is a wholly-owned subsidiary of Donaldson,
Lufkin & Jenrette, Inc., which is in turn an independently operated, indirect
subsidiary of The Equitable Companies Incorporated ("ECI"), a holding company
controlled by AXA-UAP ("AXA"), a French insurance and financial services holding
company. The Adviser is an integral part of the DLJ Securities family, and as
one of the oldest money management firms in the country, it maintains a
tradition of personalized service and performance. The address of Donaldson,
Lufkin & Jenrette, Inc. is 277 Park Avenue, New York, New York 10172. The
address of ECI is 787 Seventh Avenue, New York, New York 10019.

     As of July 1, 1997, AXA owns 60.5 of the outstanding shares of the common
stock of ECI. AXA is the holding company for an international group of insurance
and related financial services companies. AXA's insurance operations are

principally in Europe. AXA is also engaged in asset management, investment
banking and brokerage, real estate and other financial services activities in
the United States and Europe. Based on information provided by AXA, as of July
1, 1997, 18.2% of the issued ordinary shares (representing 28.2% of the voting
power) of AXA were directly or indirectly owned by Finaxa, a French holding
company ("Finaxa"). Such percentage of interest includes the interest of Colisee
Vendome, a wholly-owned subsidiary of Finaxa, which owned 3.1% of the issued
ordinary shares (representing 2.7% of the voting power) of AXA and the interest
of les Ateliers de Construction du Nord de la France-ANF ("ANF"), a 95.4% owned
subsidiary of Finaxa, which owned 0.2% of the issued ordinary shares
(representing 0.3% of the voting power) of AXA. As of July 1, 1997, 61.5% of the
issued ordinary shares (representing 72.3% of the voting power) of Finaxa were
owned by four French mutual insurance companies -- (the "Mutuelles AXA")  and
23.7% of the issued ordinary shares (representing 14.7% of the voting power) of
Finaxa were owned by Banque Paribas, a French bank ("Paribas"). Including the
ordinary shares owned by Finaxa and its subsidiaries on July 1, 1997, the
Mutuelles AXA directly and indirectly owned 24.8% of the issued ordinary shares
of AXA (representing 35.9% of the voting power). Acting as a group, the
Mutuelles AXA will continue to control AXA and Finaxa.
    

     The Investment Advisory Agreement was approved by the Board of Trustees of
the International Funds on July 25, 1995 and by the then shareholders, the
Adviser and Subadviser,



                                       12
<PAGE>


on August 23, 1995 and became effective on the same date. The Investment
Advisory Agreement is reviewed annually by the Board of Trustees and was most
recently reapproved on July 17, 1997. The Investment Advisory Agreement

continues in force for successive twelve month periods provided that such
continuation is specifically approved at least annually by a majority vote of
the Trustees who neither are interested persons of the International Funds nor
have any direct or indirect financial interest in the Investment Advisory
Agreement, cast in person at a meeting called for the purpose of voting on such
approval.

     Pursuant to the terms of the Investment Advisory Agreement, the Adviser may
retain, at its own expense, a subadviser to assist in the performance of its
services to the International Funds.

   
     For the fiscal years ended October 31, 1997, 1996 and 1995, the Developing
Markets Fund paid the Adviser fees of $506,870, $419,303 and $24,317,
respectively, and the International Equity Fund paid the Adviser fees of
$605,376, $528,653 and $50,310, respectively. Such amounts include fees that
were subsequently paid to the Subadviser.

     During the fiscal years ended October 31, 1997, 1996 and 1995, the Adviser
and Subadviser reimbursed the Developing Markets Fund $139,596, $181,527 and
$29,855, respectively, and the International Equity Fund $88,653, $112,542 and
$38,839, respectively, for operating expenses.
    

Subadviser

     The Subadviser has been retained under a subadvisory agreement by the
Adviser to assist in the performance of its services to the International Funds.

     The Subadviser, a registered investment advisor, is a wholly-owned
subsidiary of AXA. The Subadviser has hired employees from AXA, a company with a
long history of providing financial services advice.

     Certain other clients of the Adviser or Subadviser may have investment
objectives, policies and risk considerations similar to those of the
International Funds. The Adviser or Subadviser may, from time to time, make
recommendations which result in the purchase or sale of a particular security by
their other clients simultaneously with the International Funds. If transactions
on behalf of more than one client during the same period increase the demand for
securities being purchased or the supply of the securities being sold, there may
be an adverse effect on price. It is the policy of the Adviser and Subadviser to
allocate advisory recommendations and the placing of orders in a manner which is
deemed equitable by the Adviser and Subadviser to the accounts involved,
including the International Funds. When two or more of the clients of the
Adviser and Subadviser (including the International Funds) are purchasing the
same security on a given day from the same broker-dealer, such transactions may
be averaged as to price.



                                       13
<PAGE>



   
     The Fund intends to enter into arrangements with certain broker-dealers
including affiliates of the Distributor whose customers are Fund shareholders 
pursuant to which the broker-dealers may perform shareholder servicing 
functions, such as opening new shareholder accounts, processing purchase and 
redemption transactions, and responding to certain inquiries regarding the 
Fund's performance and the status of shareholder accounts. The Fund may pay 
for the electronic communications equipment maintained at the broker-dealers' 
offices that permits access to the Fund's computer files and, in addition, may
reimburse the broker-dealers at cost for personnel expenses involved in 
providing the services.

    

                       EXPENSES OF THE INTERNATIONAL FUNDS

General

     In addition to the payments to the Adviser under the investment advisory
agreement, each International Fund pays the other expenses incurred in its
organization and operations, including the costs of printing prospectuses and
other reports to existing shareholders; all expenses and fees related to
registration and filing with the SEC and with state regulatory authorities;
custody, transfer and dividend disbursing expenses; legal and auditing costs;
clerical, accounting and other office costs; fees and expenses of Trustees who
are not affiliated with the Adviser or Subadviser; costs of maintenance of
existence; and interest charges, taxes, brokerage fees and commissions.

     As to the obtaining of clerical and accounting services not required to be
provided to the International Funds by the Adviser under the investment advisory
agreement or Subadviser under the investment subadvisory agreement, the
International Funds may employ their own personnel. For such services, they also
may utilize personnel employed by the Adviser, the Subadviser or their
affiliates. In such event, the services shall be provided to the International
Funds at cost and the payments therefor must be specifically approved in advance
by the International Funds' Trustees, including a majority of its disinterested
Trustees.

Distribution Plan

     Pursuant to Rule 12b-1 adopted by the SEC under the 1940 Act, the
International Funds have adopted a Distribution Agreement (the 'Distribution
Agreement') and a Rule 12b-1 Plan for each Class of shares of each International
Fund (the "12b-1 Plans") to permit such International Fund directly or
indirectly to pay expenses associated with the distribution of shares.

     Pursuant to the Distribution Agreement and the 12b-1 Plans, the Treasurer
of the International Funds reports the amounts expended under the Distribution
Agreement and the purposes for which such expenditures were made to the Trustees
of the International Funds on a quarterly basis. Also, the 12b-1 Plans provide
that the selection and nomination of disinterested Trustees (as defined in the
1940 Act) are committed to the discretion of the disinterested Trustees




                                       14
<PAGE>


then in office. The Distribution Agreement and 12b-1 Plans may be continued
annually if approved by a majority vote of the Trustees, including a majority of
the Trustees who neither are interested persons of the International Funds nor
have any direct or indirect financial interest in the Distribution Agreement,
the 12b-1 Plans or in any other agreements related to the 12b-1 Plans, cast in
person at a meeting called for the purpose of voting on such approval. The
Distribution Agreement was initially approved by each International Fund's
Trustees on July 25, 1995 and by the then shareholders on August 23. 1995. The
Distribution Agreement was most recently reviewed and reapproved on July 17,
1997. All material amendments to the 12b-1 Plans must be approved by a vote of
the Trustees, including a majority of the Trustees who neither are interested
persons of the International Funds nor have any direct or indirect financial
interest in the 12b-1 Plans or any related agreement, cast in person at a
meeting called for the purpose of voting on such approval. In addition to such
Trustee approval, the 12b-1 Plans may not be amended in order to increase
materially the costs which the International Funds may bear pursuant to the
12b-1 Plans without the approval of a majority of the outstanding shares of such
International Funds. Each International Fund's 12b-1 Plan may be terminated
without penalty at any time by a majority vote of the disinterested Trustees, by
a majority vote of the outstanding shares of an International Fund or by the
Adviser. Any agreement related to the 12b-1 Plans may be terminated at any time,
without payment of any penalty, by a majority vote of the independent Trustees
or by majority vote of the outstanding shares of an International Fund on not
more than 60 days notice to any other party to the agreement, and will terminate
automatically in the event of assignment.

     With respect to sales of an International Fund's Class B shares through a
broker-dealer, the Distributor pays the broker-dealer a concession at the time
of sale. In addition, an ongoing maintenance fee may be paid to broker-dealers
on sales of both Class A shares and Class B shares. Pursuant to the
International Funds' 12b-1 Plans, the Distributor is then reimbursed for such
payments with amounts paid from the assets of such International Fund. The
payments to the broker-dealer, although an International Fund expense which is
paid by all shareholders, will only directly benefit investors who purchase
their shares through a broker-dealer rather than from the International Funds.
Broker-dealers who sell shares of the International Funds may provide services
to their customers that are not available to investors who purchase their shares
directly from the International Funds. Investors who purchase their shares
directly from an International Fund will pay a pro rata share of such
International Fund's expenses of encouraging broker-dealers to provide such
services but not receive any of the direct benefits of such services. The
payments to the broker-dealers will continue to be paid for as long as the
related assets remain in the International Funds.

     Pursuant to the provisions of the 12b-1 Plans and the Distribution
Agreement, each International Fund pays a distribution services fee each month
to the Distributor, with respect to the Class A shares of each International
Fund at an annual rate of up to .25 of 1%, and with respect to the Class B
shares of each International Fund the annual rate may be up to 1%, of the

aggregate average daily net assets attributable to Class A shares and Class B
shares, respectively, of each International Fund.

                      PURCHASES, REDEMPTIONS, EXCHANGES AND
                           SYSTEMATIC WITHDRAWAL PLAN

The following information supplements that set forth in the International Funds'
Prospectus under the heading "Purchases, Redemptions and Shareholder Services."

Purchases

     Shares of the International Funds are offered at the respective net asset
value per share next determined following receipt of a purchase order in proper
form by the International Funds, the International Funds' transfer agent, FPS
Services, Inc. (the "Transfer Agent"), or by the Distributor. The International
Funds calculate net asset value per share as of the close of the regular session
of the New York Stock Exchange, (the "NYSE") which is generally 4:00 p.m. New
York City time on each day that trading is conducted on the NYSE.

     Orders for the purchase of shares of an International Fund become effective
at the next transaction time after Federal funds or bank wire monies become
available to the Transfer Agent for a shareholder's investment. Federal funds
are a bank's deposits in a Federal Reserve Bank. These funds can be transferred
by Federal Reserve wire from the account of one member bank to that of another
member bank on the same day and are considered to be immediately available
funds. Investors should note that their banks may impose a charge for this
service. Money transmitted by a check drawn on a member of the Federal Reserve
System is converted to Federal Funds in one business day following receipt.
Checks drawn on banks which are not members of the Federal Reserve System may
take longer. All payments (including checks from individual investors) must be
in United States dollars.

     All shares purchased are confirmed to each shareholder and are credited to
such shareholder's account at net asset value and with respect to the Class A
shares, less any applicable initial sales charge. As a convenience to the
investor and to avoid unnecessary expense to the International Funds, share
certificates representing shares of the International Fund purchased are not
issued except upon the written request of the shareholder and payment of a fee
in the amount of $50 for such share issuance. The International Funds retain the
right to waive such fee in their sole discretion. This facilitates later
redemption and relieves the shareholder of the responsibility and inconvenience
of preventing the share certificates from becoming lost or stolen. No
certificates are issued for fractional shares (although such shares remain in
the shareholder's account on the books of the International Funds).

   
     Shareholders maintaining Fund accounts through brokerage firms and other
institutions should be aware that such institutions may necessarily set 
deadlines for receipt of transaction orders from their clients that are 

earlier than the transaction times of the Fund itself so that the institutions
may properly process such orders prior to their transmittal to the Fund or the
Distributor. Should an investor place a transaction order with such an
institution after its deadline, the institution may not effect the order with
the Fund until the next business day. Accordingly, an investor should
familiarize himself or herself with the deadlines set by his or her institution.
(For example, a brokerage firm may accept purchase orders from its customers 
up to
    



                                       16
<PAGE>


   
2:15 p.m. for issuance at the 4:00 p.m. transaction time and price.) A brokerage
firm acting on behalf of a customer in connection with transactions in Fund
shares is subject to the same legal obligations imposed on it generally in
connection with transactions in securities for a customer, including the
obligation to act promptly and accurately.
    

Redemptions

   
     Shares of the International Funds may be redeemed at a redemption price
equal to the net asset value per share, as next computed as of the regular
trading session of the NYSE following the receipt in proper form by the
International Funds of the shares tendered for redemption, less any applicable
contingent deferred sales charge in the case of Class B shares and certain
redemptions of Class A shares.
    

     Payment of the redemption price may be made either in cash or in portfolio
securities (selected in the discretion of the Trustees and taken at their value
used in determining the redemption price), or partly in cash and partly in
portfolio securities. However, payments will be made wholly in cash unless the
Trustees believe that economic conditions exist which would make such a practice
detrimental to the best interest of the International Funds. If payment for
shares redeemed is made wholly or partly in portfolio securities, brokerage
costs may be incurred by the investor in converting the securities to cash. See
the Prospectus for a description of the contingent deferred sales charge which
may be applicable to certain redemptions.

     To redeem shares, the registered owner or owners should forward a letter to
the Transfer Agent containing a request for redemption of such shares at the
next determined net asset value per share. Alternatively, the shareholder may
elect the right to redeem shares by telephone as described in the Prospectus. If
the shares are represented by share certificates, investors should forward the
appropriate share certificates, endorsed in blank or with blank stock powers
attached, to the Transfer Agent with the request that the shares represented
thereby or a portion thereof be redeemed at the next determined net asset value

per share. The share assignment form on the reverse side of each share
certificate surrendered to the Transfer Agent for redemption must be signed by
the registered owner or owners exactly as the registered name appears on the
face of the certificate or, in the alternative, a stock power signed in the same
manner may be attached to the share certificate or certificates, or, where
tender is made by mail, separately mailed to the Transfer Agent. The signature
or signatures on the assignment form must be guaranteed in the manner described
below.

     If the total value of the shares being redeemed exceeds $50,000 (before
deducting any applicable contingent deferred sales charge) or a redemption
request directs proceeds to a party other than the registered account owner(s),
the signature or signatures on the letter or the endorsement must be guaranteed
by an "eligible guarantor institution" as defined in Rule 17Ad-15 under the
Securities Exchange Act of 1934. Eligible guarantor institutions include banks,
brokers, dealers, credit unions, national securities exchanges, registered
securities associations, clearing agencies and savings associations. A
broker-dealer guaranteeing signatures must be a member of a clearing corporation
or maintain net capital of at least $100,000. Credit unions must be authorized
to issue signature guarantees. Signature guarantees will be accepted from any



                                       17
<PAGE>


eligible guarantor institution which participates in a signature guarantee
program. Additional documents may be required for redemption of corporate,
partnership or fiduciary accounts.

     The requirement for a guaranteed signature is for the protection of the
shareholder in that it is intended to prevent an unauthorized person from
redeeming his shares and obtaining the redemption proceeds.

Exchanges

     Shares of one class of an International Fund can be exchanged for shares of
the same class of another International Fund, shares of the Winthrop Municipal
Money Fund and the Winthrop U.S. Government Money Fund (collectively, the "Money
Funds") and shares of the same class of Winthrop Growth Fund, Winthrop Fixed
Income Fund, Winthrop Small Company Value Fund, Winthrop Growth and Income Fund
and Winthrop Municipal Trust Fund (the "Focus Funds"). Shareholders may exchange
shares by mail. Shareholders or the shareholders' investment dealer of record
may exchange shares by telephone.

     In the case of each Money Fund and Focus Fund, the exchange privilege is
available only in those jurisdictions where shares of such Fund may be legally
sold. In addition, the exchange privilege is available only when payment for the
shares to be redeemed has been made and the shares exchanged are held by the
Transfer Agent.

     Only those shareholders who have had shares in an International Fund for at
least seven days may exchange all or part of those shares for shares of the

other International Fund, the Money Funds or Focus Funds, and no partial
exchange may be made if, as a result, the shareholders' interest in an
International Fund would be reduced to less than $250. The minimum initial
exchange into another International Fund is $250.

     All exchanges into either of the Money Funds or any of the Focus Funds are
subject to the minimum investment requirements and any other applicable terms
set forth in the Prospectus for the relevant Money Fund or Focus Fund whose
shares are being acquired. If for these or other reasons the exchange cannot be
effected, the shareholder will be so notified.

     The exchange privilege is intended to provide shareholders with a
convenient way to switch their investments when their objectives or perceived
market conditions suggest a change. The exchange privilege is not meant to
afford shareholders an investment vehicle to play short term swings in the stock
market by engaging in frequent transactions in and out of the International
Funds, the Money Funds and the Focus Funds. Shareholders who engage in such
frequent transactions may be prohibited from or restricted in placing future
exchange orders.

     Exchanges of shares are subject to the other requirements of the fund into
which exchanges are made. Annual fund operating expenses for such fund may be
higher and a sales 



                                       18
<PAGE>


   
charge differential may apply. See "Expenses of Winthrop" and "Additional
Shareholder Services - Exchange Privilege" in the Prospectus for a description
of these expense differences.
    

Systematic Withdrawal Plan^

     Shares of an International Fund owned by a participant in the International
Funds' systematic withdrawal plan will be redeemed as necessary to meet
withdrawal payments. A contingent deferred sales charge which would otherwise be
imposed will be waived in connection with redemptions made pursuant to the
International Funds' systematic withdrawal plan up to 1% monthly or 3% quarterly
of an account ^ not to exceed 10% of total market value over any 12 month
rolling period. Systematic withdrawals elected on a semi-annual or annual basis
are not eligible for the waiver. See the Prospectus for a description of the
contingent deferred sales charge. The systematic withdrawal plan may be
terminated at any time by the shareholder or the International Funds.

     Redemption of shares for withdrawal purposes may reduce or even liquidate
an account. While an occasional lump sum investment may be made by a shareholder
who is maintaining a systematic withdrawal plan, such investment should normally
be an amount equivalent to three times the annual withdrawal or $5,000 whichever
is less.


                                RETIREMENT PLANS

     Each of the International Funds may be a suitable investment vehicle for
part or all of the assets held in various tax sheltered retirement plans, such
as those listed below. Semper Trust Company serves as custodian under these
prototype retirement plans and charges an annual account maintenance fee of $15
per participant, regardless of the number of Funds selected. Persons desiring
information concerning these plans should write or telephone the International
Funds' Transfer Agent. While the International Funds' reserve the right to
suspend sales of its shares in response to conditions in the securities markets
or for other reasons, it is anticipated that any such suspension of sales would
not apply to the types of plans listed below.

Individual Retirement Accounts ("IRA")

   
     The Adviser has available a prototype form of a Traditional IRA for
investment in shares of any one or more International Funds. Under the Code,
individuals may currently make IRA contributions of up to $2,000 annually. 
Married  individuals filing jointly may contribute up to $2,000 for each spouse
if the combined compensation of both spouses is at least equal to the
contributed amount. Contributions to an IRA may be wholly or partly
tax-deductible, depending upon the contributor's income level and participation
in an employer-sponsored retirement plan. The income earned on shares held in an
IRA is not subject to federal income tax until withdrawn in accordance with the
Code. Investors may be subject to penalties or additional taxes on contributions
to or withdrawals from IRAs under certain circumstances. As with tax-deductible
contributions, taxes on the income earned from nondeductible IRA contributions
will be deferred until distributed from the IRA.
    



                                       19
<PAGE>


   
     The Adviser has available a prototype form of the new Roth IRA. Unlike 
Traditional IRA's, contributions to a Roth IRA are not currently deductible.
However, the amounts within the Roth IRA accounts will accumulate tax-free, and
qualified distributions from the International Funds will not be included in a
shareholder's taxable income. An individual may contribute a maximum of $2,000
annually to a Roth IRA ($4,000 for joint returns). However, such limit is
calculated in the aggregate with contributions to traditional IRA's. In
addition, Roth IRA's are not available to individuals above certain income
levels.

     The Adviser also has available a prototype form of the new Education IRA
for investment in shares of any one or more International Funds. Like the Roth
IRA, contributions are not currently deductible. However, the investment
earnings accumulate tax-free, and qualifying distributions used for higher
education expenses are not taxable. An individual may contribute a maximum of

$500 per account annually. In addition, Educational IRA's are not available to
individuals above certain income levels.
    

Simplified Employee Pension Plan ("SEP/IRA")

     A SEP/IRA is available for investment and may be established on a group
basis by an employer who wishes to sponsor a tax-sheltered retirement program by
making IRA contributions on behalf of all eligible employees.

Savings Incentive Match Plan for Employees ("SIMPLE") - SIMPLE IRA and SIMPLE
401(k)

     SIMPLE plans offer employers with 100 or fewer eligible employees who
earned at least $5,000 from the employer in the preceding calendar year, the
ability to establish a retirement plan that permits employee contributions. An
employer may also elect to make additional contributions to these Plans. Please
telephone Winthrop's shareholder servicing representatives at (800) 225-8011 for
more information.

Employer-Sponsored Retirement Plans

     The Adviser has a prototype retirement plan available which provides for
investment of plan assets in shares of any one or more International Funds. The
prototype retirement plan may be used by sole proprietors and partnerships as
well as corporations to establish a tax qualified profit sharing plan or money
purchase pension plan (or both) of their own.

     Under the prototype retirement plan, an employer may make annual
tax-deductible contributions for allocation to the accounts of the plan
participants to the maximum extent permitted by the federal tax law for the type
of plan implemented. The Adviser has received favorable opinion letters from the
IRS that the prototype retirement plan is acceptable by qualified employers.

Self-Directed Retirement Plans



                                       20
<PAGE>


     Shares of the International Fund may be suitable for self-directed IRA
accounts and prototype retirement plans such as those developed by Donaldson,
Lufkin & Jenrette Securities Corporation, an affiliate of the Adviser and
Winthrop's Distributor.


                                 NET ASSET VALUE

   
     Shares of each International Fund will be priced at the net asset value per
share as computed each International Fund Business Day in accordance with the
International Funds' Agreement and Declaration of Trust and By-Laws. For this

purpose, an International Fund Business Day is any day on which the NYSE is open
for business, typically, Monday through Friday exclusive of New Year's Day,
Martin Luther King Jr. Day, Washington's Birthday, Memorial Day, Independence
Day, Labor Day, Thanksgiving Day, Christmas Day and Good Friday.
    

     The net asset value of the shares of each International Fund is determined
as of the close of the regular session on the NYSE, which is generally at 4:00
p.m., New York City time, on each day that trading is conducted on the NYSE. The
net asset value per share is calculated by taking the sum of the value of each
International Fund's investments and any cash or other assets, subtracting
liabilities, and dividing by the total number of shares outstanding. All
expenses, including the fees payable to the Adviser, are accrued daily. For net
asset value determination purposes, securities quoted in foreign currencies are
translated into U.S. dollars at the current exchange rates (determined at 4:00
p.m. London time) or at such rates as the Trustees may determine. As a result,
to the extent an International Fund holds securities quoted or denominated in a
foreign currency, fluctuations in the value of such currencies in relation to
the U.S. dollar will affect the net asset value of such International Fund's
shares even though there has not been any change in the value of such securities
as quoted in the foreign currency. For purposes of this computation, the
securities in each International Fund's portfolio are, except as described
below, valued at their current market value determined on the basis of market
quotations or, if such quotations are not readily available, such other method
as the Trustees believe would accurately reflect their fair value.

     Foreign securities trading may not take place on all days on which the NYSE
is open. Further, trading takes place in various foreign markets on days on
which the NYSE is not open. Accordingly, the determination of the net asset
value of an International Fund's shares may not take place contemporaneously
with the determination of the prices of investments held by such International
Fund. Events affecting the values of investments that occur between the time
their prices are determined and the close of regular trading on the NYSE on each
day that the NYSE is open will not be reflected in the net asset value of an
International Fund's shares unless the Adviser or Subadviser, under the
supervision of such International Fund's Board of Trustees, determines that the
particular event would materially affect net asset value. As a result, the net
asset value of an International Fund's shares may be significantly affected by
such trading on days when a shareholder has no access to such International
Fund.



                                       21
<PAGE>


     For purposes of the computation of net asset value, each of the
International Funds values securities held in its respective portfolios as
follows: readily marketable portfolio securities listed on an exchange are
valued, except as indicated below, at the last sale price at the close of the
exchange on the business day as of which such value is being determined. If
there has been no sale on such day, the securities are valued at the mean of the
closing bid and asked prices on such day. If no bid or asked prices are quoted

on such day, then the security is valued by such method as the Trustees of the
International Funds shall determine in good faith to reflect its fair value.

     Readily marketable securities, including certain options, not listed on an
exchange but admitted to trading on the National Association of Securities
Dealers Automatic Quotations, Inc. ("NASDAQ") National List (the "List") are
valued in like manner. Portfolio securities traded on more than one exchange are
valued at the last sale price on the business day as of which such value is
being determined at the close of the exchange representing the principal market
for such securities.

     Readily marketable securities, including certain options traded only in the
over-the-counter market and listed securities whose primary market is believed
by the Adviser or Subadviser to be over-the-counter (excluding those admitted to
trading on the List) are valued at the mean of the current bid and asked prices
as reported by such sources as the Trustees of the International Funds deem
appropriate to reflect their fair market value. However, fixed-income securities
(except short-term securities) may be valued on the basis of prices provided by
a pricing service when such prices are believed by the Adviser or Subadviser to
reflect the fair market value of such securities. The prices provided by a
pricing service are determined without regard to bid or last sale prices but
take into account institutional size trading in similar groups of securities and
any developments related to specific securities. Portfolio securities underlying
listed call options will be valued at their market price and reflected in net
assets accordingly. Premiums received on call options written by an
International Fund will be included in the liability section of the Statement of
Assets and Liabilities as a deferred credit and subsequently adjusted
(marked-to-market) to the current market value of the option written.
Investments for which market quotations are not readily available are valued at
fair value as determined in good faith by the Trustees of the International
Funds.

                       DIVIDENDS, DISTRIBUTIONS AND TAXES

     The International Funds intend to distribute to shareholders of the
International Funds on an annual basis, substantially all of such respective
periods' net investment income, if any, for each respective International Fund.
   
     Upon a redemption or other disposition of shares of a Fund, a shareholder
will generally recognize gain or loss in an amount equal to the difference
between the amount realized and the shareholder's tax basis in such shares.
Generally, such gain or loss will be capital gain or loss and will be long-term
capital gain or loss if the shareholder's holding period for such shares exceeds
one year. Long-term capital gain of a non-corporate shareholder is generally
subject to a maximum tax rate of 28% in respect of property held for more than
one year and to a maximum tax rate of 20% in respect of property held in excess
of 18 months.
    
     Capital gains (short-term and long-term), if any, realized by each of the
International Funds during their fiscal year will be distributed to the
respective shareholders shortly after the end of such fiscal year.

     Each income dividend and capital gains distribution, if any, declared by
the International Funds on the outstanding shares of any International Fund

will, at the election of each 



                                       22
<PAGE>


shareholder, be paid in cash or reinvested in additional full and fractional
shares of that International Fund at the net asset value as of the close of
business on the payment date. Such distributions, to the extent they would
otherwise be taxable, will be taxable to shareholders regardless of whether paid
in cash or reinvested in additional shares. An election to receive dividends and
distributions in cash or shares is made at the time of the initial investment
and may be changed by notice received by the International Funds from a
shareholder at least 30 days prior to the record date for a particular dividend
or distribution on shares of each International Fund. There is no charge in
connection with the reinvestment of dividends and capital gains distributions.

     There is no fixed dividend rate and there can be no assurance that an
International Fund will pay any dividends or realize any gains. The amount of
any dividend or distribution paid by each International Fund depends upon the
realization by the International Fund of income and capital gains from that
International Fund's investments. All dividends and distributions will be made
to shareholders of an International Fund solely from assets of that
International Fund.

     Payment (either in cash or in portfolio securities) received by a
shareholder upon redemption of his shares, assuming the shares constitute
capital assets in his hands, will result in long-term or short-term capital
gains (or losses) depending upon the shareholder's holding period and basis in
respect of shares redeemed. Any loss realized by a shareholder on the sale of
International Fund shares held for six months or less will be treated for
Federal income tax purposes as a long-term capital loss to the extent of any
distributions of long-term capital gains received by the shareholder with
respect to such shares. Note that any loss realized on the sale of shares will
be disallowed to the extent the shares disposed of are replaced within a period
of 61 days beginning 30 days before the disposition of such shares. In such
case, the basis of the shares acquired will be adjusted to reflect the
disallowed loss.

   
     Each International Fund intends to continue to qualify as a regulated
investment company under Subchapter M of the Internal Revenue Code of 1986 (the
"Code"), as amended, so that it will not be liable for Federal income taxes to
the extent that its net taxable income and net capital gains are distributed.
Accordingly, each International Fund must, among other things, (a) derive at
least 90% of its gross income from dividends, interest, payments with respect to
securities loans, gains from the sale or other disposition of stock or
securities or other foreign currencies, or other income (including but not
limited to gains from futures and forward contracts) derived with respect to its
business of investing in stock, securities or currencies; and (b) diversify
its holdings so that, at the end of each fiscal quarter, (i) at least 50% of the
market value of the International Fund's assets is represented by cash, U.S.

Government securities and other securities, with such other securities limited,
in respect of any one issuer, to an amount not greater than 5% of the
International Fund's assets and 10% of the outstanding voting securities of such
issuer, and (ii) not more than 25% of the value of its assets is invested in the
securities of any one issuer (other than U.S. Government securities). Foreign
currency gains that are not 'directly related' to the International Fund's
principal business of investing in stock or securities may be excluded by
Treasury Regulations from income that counts toward the 90% of gross income
requirement described above. The Treasury Department has not yet issued any
such regulations. For Federal income tax purposes, dividends of net ordinary
income and distributions 
    



                                       23
<PAGE>


of any net short-term capital gains in excess of any net long-term capital
losses are treated as ordinary income of the shareholders, and distributions of
net long-term capital gains in excess of any net short-term capital losses are
taxable to shareholders as long-term capital gains irrespective of the length of
time the shareholder has held shares of the International Fund.

     Since the International Funds are not treated as a single entity for
Federal income tax purposes, the performance of one International Fund will have
no effect on the income tax liability of shareholders of another International
Fund. A dividend or capital gains distribution with respect to shares of any
International Fund held by a tax-deferred or qualified retirement plan, such as
an IRA, Keogh Plan or corporate pension or profit sharing plan, will not be
taxable to the plan. Distributions from such plans will be taxable to individual
participants under applicable tax rules without regard to the character of the
income earned by the qualified plan.

     As a regulated investment company, each International Fund will not be
subject to Federal income tax on income and gains distributed to shareholders if
it distributes at least 90% of its investment company taxable income to
shareholders each year but will be subject to tax on its income and gains to the
extent that it does not distribute to its shareholders an amount equal to such
income and gains. In addition, each International Fund will be subject to a
nondeductible 4% excise tax on the excess, if any, of certain required
distribution amounts over the amounts actually distributed by that International
Fund. To the extent possible, each International Fund intends to make such
distributions as may be necessary to avoid this excise tax.

     For Federal income tax purposes, dividends that are declared by an
International Fund in October, November or December as of a record date in such
month and actually paid in January of the following year will be treated as if
they were paid on December 31 of the year in which they were declared.
Therefore, such dividends will generally be taxable to a shareholder in the year
declared rather than the year paid.

     Shareholders will be advised annually as to the Federal tax status of

dividends and capital gains distributions made by each International Fund for
the preceding year.

     Some of the investment practices of each International Fund are subject to
special provisions that, among other things, may defer the use of certain losses
of such International Funds and affect the holding period of the securities held
by the International Funds and the character of the gains or losses realized.
These provisions may also require the International Fund to mark-to-market some
of the positions in their respective portfolios (i.e., treat them as if they
were closed out), which may cause such International Funds to recognize income
without receiving cash with which to make distributions in amounts necessary to
satisfy the distribution requirements for qualification as a regulated
investment company and for avoiding income and excise taxes. Each International
Fund will monitor its transactions and may make certain tax elections in order
to mitigate the effect of these rules and prevent disqualification of the
International Fund as a regulated investment company.

     The International Funds may make investments denominated in a foreign
currency. Gains or losses attributable to dispositions of foreign currency or to
foreign currency contracts, or to 



                                       24
<PAGE>


fluctuations in exchange rates between the time an International Fund accrues
income or receivables or expenses or other liabilities denominated in a foreign
currency and the time the International Fund actually collects such income or
pays such liabilities, are generally treated as ordinary income or ordinary
loss. Similarly, gains or losses on the disposition of debt securities held by
an International Fund, if any, denominated in foreign currency, to the extent
attributable to fluctuations in exchange rates between the acquisition and
disposition dates, also are generally treated as ordinary income or loss. These
gains and losses increase or decrease the amount of the International Fund's net
investment income available for distribution.

     If an International Fund owns shares in certain foreign investment
entities, referred to as passive foreign investment companies ("PFICs"), such
International Fund may be subject to Federal income tax, and additional charges
in the nature of interest, on a portion of any "excess distribution" from such
company or gain from the disposition of such shares, even if the entire
distribution or gain is distributed by the International Fund to its
shareholders. If an International Fund were able and elected to treat a PFIC as
a "qualified electing fund," in lieu of the treatment described above, such
International Fund would be required each year to include in income, the
International Fund's pro rata share of the ordinary earnings and net capital
gains of the company, whether or not actually received by the International
Fund. Proposed Treasury Regulations and newly enacted provisions of the code 
would each allow certain regulated investment companies to elect to
mark-to-market their stock in certain PFICs at the end of each taxable year,
whereby the International Fund would include in its taxable income each year any
unrealized gain on such PFIC investments. In order to distribute the income

includible in the International Fund's income under either election, maintain
its qualification as a regulated investment company, and avoid income or excise
taxes, such International Fund may be required to liquidate portfolio securities
that it might otherwise have continued to hold. In the case of the proposed
Treasury Regulations, there can be no assurance  that these regulations will be
finalized in the form proposed or as to the effective date of any such final
regulations.

     If, as is expected, more than 50 % of the value of the each International
Fund's total assets at the close of its taxable year consists of stock or
securities of foreign corporations, it will be eligible to file an election with
the Internal Revenue Service to "pass through" to its shareholders the amount of
foreign income taxes (including withholding taxes) paid by such International
Fund. Pursuant to this election a shareholder will: (1) include in gross income
(in addition to the taxable dividends actually received) the shareholder's pro
rata share of the foreign income taxes paid by such International Fund; (2)
treat the shareholder's pro rata share of the foreign income taxes paid by such
International Fund as paid by the shareholder; and (3) subject to certain
limitations, either deduct the pro rata share of such foreign income taxes in
computing the shareholder's taxable income or use it as a foreign tax credit
against federal income taxes. Each shareholder will be notified within 60 days
after the close of an International Fund's taxable year whether the foreign
income taxes paid by an International Fund will "pass through" for that year
and, if so, such notification will designate the shareholder's portion of the
foreign income taxes paid to each country and the portion of dividends that
represents income derived from sources derived within each country.

     Generally, a credit for foreign taxes is subject to the limitation that it
may not exceed the shareholder's Federal income tax (before the credit)
attributable to the shareholder's total foreign



                                       25
<PAGE>


source taxable income. For this purpose, the portion of dividends and
distributions paid by each International Fund from its foreign source income
will be treated as foreign source income. Each International Fund's gains and
losses from the sale of securities, and certain currency gains and losses, will
generally be treated as derived from United States sources. The limitation on
the foreign tax credit is applied separately to foreign source "passive income,"
such as dividend income. Because of these limitations, a shareholder may be
unable to claim a credit for the full amount of the shareholder's proportionate
share of foreign income taxes paid by such International Fund. In addition, no
deduction for foreign income taxes may be claimed by a shareholder who does not
itemize deductions. Shareholders are advised to consult their own tax advisers
on the application of the foreign tax credit rules to their own particular
circumstances.

       

     Each International Fund is required to withhold and remit to the U.S.

Treasury 31% of the dividends or the proceeds of any redemptions or exchanges of
shares with respect to any shareholder who fails to furnish the International
Funds with a correct taxpayer identification number, who under-reports dividend
or interest income or who fails to certify to the International Funds that he or
she is not subject to such withholding. An individual's tax identification
number is his or her social security number.

     The foregoing discussion is a general summary of certain current federal
income tax laws regarding the International Funds. The discussion does not
purport to deal with all of the federal income tax consequences applicable to
the International Funds, or to all categories of investors, some of whom may be
subject to special rules. Each prospective shareholder should consult with his
or her own professional tax adviser regarding federal, state and local tax
consequences of ownership of shares of the International Funds.


                             PORTFOLIO TRANSACTIONS

     Subject to the general supervision of the Board of Trustees of the
International Funds, the Adviser and Subadviser are responsible for the
investment decisions and the placing of the orders for portfolio transactions
for the International Funds. Portfolio transactions for the International Funds
are normally effected by brokers.

     The International Funds have no obligation to enter into transactions in
portfolio securities with any broker, dealer, issuer, underwriter or other
entity. In placing orders, it is the policy of the International Funds to obtain
the best price and execution for its transactions. Where best price and
execution may be obtained from more than one broker or dealer, the Adviser or
Subadviser may, in its discretion, purchase and sell securities through brokers
and dealers who provide research, statistical and other information to the
Adviser or Subadviser. Such services may be used by the Adviser or Subadviser
for all of their investment advisory accounts, and accordingly, not all such
services may be used by the Adviser or Subadviser in connection with the
International Funds. If an International Fund determines in good faith that the
amount of transaction costs charged by a broker or dealer is reasonable in
relation to the 



                                       26
<PAGE>


value of the brokerage and research and statistical services provided by the
executing broker or dealer, the International Fund may utilize such broker or
dealer although the transaction costs of another broker or dealer are lower. The
supplemental information received from a broker or dealer is in addition to the
services required to be performed by the Adviser under the Investment Advisory
Agreement or Subadviser under the Investment Subadvisory Agreement, and the
expenses of the Adviser or Subadviser will not necessarily be reduced as a
result of the receipt of such information.

   

     Neither the International Funds, the Adviser nor the Subadviser on behalf
of the International Funds have entered into agreements or understandings with
any broker or dealer regarding the placement of securities transactions. Because
of research or information to the Adviser or Subadviser for use in rendering
investment advice to the International Funds, such information may be supplied
at no cost to the Adviser or Subadviser and, therefore, may have the effect of
reducing the expenses of the Adviser or Subadviser in rendering advice to the
International Funds. While it is impossible to place an actual dollar value on
such investment information, its receipt by the Adviser and Subadviser probably
does not reduce the overall expenses of the Adviser or Subadviser to any
material extent.
    

     The investment information provided to the Adviser and Subadviser is of the
types described in Section 28(e)(3) of the Securities Exchange Act of 1934 and
is designed to augment the Adviser's and Subadviser's own internal research and
investment strategy capabilities. Research and statistical services furnished by
brokers through which the International Funds effect securities transactions are
used by the Adviser and Subadviser in carrying out its investment management
responsibilities with respect to all its client accounts but not all such
services may be utilized by the Adviser and Subadviser in connection with the
International Funds.

     The International Funds may deal in some instances in equity securities
which are not listed on an exchange but are traded in the over-the-counter
market. Where transactions are executed in the over-the-counter market, the
International Funds seek to deal with the primary market-makers, but when
necessary in order to obtain the best price and execution, it utilizes the
services of others. In all cases, the International Funds will attempt to
negotiate best execution.

     The International Funds may from time to time place orders for the purchase
or sale of securities (including listed call options) with DLJ Securities, the
International Funds' Distributor or other affiliates in accordance with the
provisions of Section 11(a) of the Securities Exchange Act of 1934 referred to
below. With respect to orders placed with DLJ Securities for execution on a
national securities exchange, commissions received must conform to Section
17(e)(2)(A) of the 1940 Act and Rule 17e-1 thereunder, which permit an
affiliated person of a registered investment company (such as the International
Funds), or any affiliated person of such person, to receive a brokerage
commission from such registered investment company provided that such commission
is reasonable and fair compared to the commissions received by other brokers in
connection with comparable transactions involving similar securities during a
comparable period of time.



                                       27
<PAGE>


     Pursuant to Section 11(a) of the Securities Exchange Act of 1934, DLJ
Securities and its affiliates are restricted as to the nature and extent of the
brokerage services they may perform for the International Funds. The SEC has

adopted rules under Section 11(a) which permit an investment adviser to a
registered investment company, or the adviser's affiliates, to receive
compensation for effecting, on a national securities exchange, transactions in
portfolio securities of such investment company, including causing such
transactions to be transmitted, executed, cleared and settled and arranging for
unaffiliated brokers to execute such transactions.

     To the extent permitted by such rule, DLJ Securities and its affiliates may
receive compensation relating to transactions in portfolio securities of the
International Funds provided that each International Fund enter into a written
agreement, as required by such rules, with that firm authorizing it to retain
compensation for such services. The Trustees of the International Funds have
granted authorization conforming to the requirements of Section 11(a) to the
Adviser and Subadviser to effect transactions in portfolio securities of the
International Funds through their affiliates, DLJ Securities and Autranet, Inc.

   
     For the years ended October 31, 1997, 1996 and 1995, brokerage commissions
paid by the Developing Markets Fund were $232,122, $263,491 and $69,888,
respectively, and the International Equity Fund were $263,075, $363,085 and
$112,747, respectively. DLJ Securities and Autranet, Inc., affiliates of the
Advisor and Subadvisor, did not receive any amounts of such brokerage
commissions.
    


                               PORTFOLIO TURNOVER

   
     Each International Fund's average annual portfolio turnover rate is the
ratio of the lesser of sales or purchases to the monthly average value of such
securities owned during the year, excluding from both the numerator and the
denominator all securities with maturities at the time of acquisition of one
year or less. For the year ended October 31, 1997, the portfolio turnover rates
for the Developing Markets Fund and the International Equity Fund were 52.8% and
73.9%, respectively. A higher rate involves greater transaction costs to an
International Fund and may result in the realization of net capital gains, which
would be taxable to shareholders when distributed.
    

                       INVESTMENT PERFORMANCE INFORMATION

     Each International Fund may furnish data about its investment performance
in advertisements, sales literature and reports to shareholders. "Total return"
represents the change in value of $1,000 invested at the maximum public offering
price for a period assuming reinvestment of all dividends and distributions.

     Quotations of yield will be based on the investment income per share earned
during a particular 30 day period, less expenses accrued during the period ("net
investment income") and will be computed by dividing net investment income by
the maximum offering price per share on the last day of the period, according to
the following formula:




                                       28
<PAGE>


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

where A = dividends and interest earned during the period, B = expenses accrued
for the period (net of any reimbursements), C = the average daily number of
shares outstanding during the period that were entitled to receive dividends,
and D = the maximum offering price per share on the last day of the period.

     Quotations of average annual total return will reflect only the performance
of an investment in any International Fund during the particular time period
shown. Each International Fund's total return and current yield may vary from
time to time depending on market conditions, the compositions of its portfolio
and operating expenses. These factors and possible differences in the methods
used in calculating yield should be considered when comparing each International
Fund's current yield to yields published for other investment companies and
other investment vehicles. Average annual total return and yield should also be
considered relative to change in the value of each International Fund's shares
and the risks associated with each International Fund's investment objectives,
policies and risk considerations. At any time in the future, average annual
total returns and yield may be higher or lower than past total returns and
yields and there can be no assurance that any historical return or yield will
continue.

     From time to time evaluations of performance are made by independent
sources that may be used in advertisements concerning each International Fund.
These sources include Lipper Analytical Services, Weisenberger Investment
Company Service, Barron's, Business Week, Kiplinger's Personal Finance,
Financial World, Forbes, Fortune, Money, Personal Investor, Sylvia Porter's
Personal Finance, Bank Rate Monitor, Morningstar and The Wall Street Journal.

     In connection with communicating its yield or average annual total return
to current or prospective shareholders, each International Fund may also compare
these figures to the performance of other mutual funds tracked by mutual fund
rating services or to other unmanaged indexes which may assume reinvestment of
dividends but generally do not reflect deductions for administrative and
management costs.

     Quotations of each International Fund's average annual total return will
represent the average annual compounded rate of return of a hypothetical
investment in each International Fund over periods of 1, 5, and 10 years (or up
to the life of each International Fund), and are calculated pursuant to the
following formula:

                                   P(1+T)^n=ERV

(where P = a hypothetical initial payment of $1,000, T = the average annual
total return, n = the number of years, and ERV = the redeemable value at the end
of the period of a $1,000 payment made at the beginning of the period). All

average annual total return figures will reflect the deduction of International
Fund expenses (net of certain expenses reimbursed by the Adviser and Subadviser)
on an annual basis, and will assume that all dividends and distributions are



                                       29
<PAGE>


reinvested and will deduct the maximum sales charge, if any is imposed. The
International Funds may also quote total return that eliminates any applicable
initial sales charge or contingent deferred sales charge.

   
     For the year ended October 31, 1997, the average annual total return for
the Class A and Class B shares of the Developing Markets Fund was -4.18% and
- -4.83%, respectively, and +10.02% and +9.23% for Class A and Class B shares,
respectively, of the International Equity Fund. Assuming deduction of the
maximum sales charge, the average annual total return for the Class A and Class
B shares of the Developing Markets Fund was -9.69% and -8.64%, respectively, and
+3.69% and +5.23% for Class A and Class B shares, respectively, of the
International Equity Fund. For the period from inception of the International
Funds' investment operations on September 13, 1995 through October 31, 1997, the
average annual total return for the Class A and Class B shares of the Developing
Markets Fund was -2.17% and -2.94%, respectively, and +6.43% and +5.64% for
Class A and Class B shares, respectively, of the International Equity Fund.
Assuming deduction of the maximum sales charge, the average annual total return
for the Class A and Class B shares of the Developing Markets Fund was -4.85% and
- -3.86%, respectively, and +3.51% and +4.75% for Class A and Class B shares,
respectively, of the International Equity Fund.

                               GENERAL INFORMATION

Organization and Capitalization

     The Trust was formed on May 31, 1995 as a 'business trust' under the laws
of the State of Delaware.

     The Agreement and Declaration of Trust provides that no Trustee, officer,
employee or agent of the International Funds is liable to the International
Funds or to a shareholder, nor is any Trustee, officer, employee or agent liable
to any third persons in connection with the affairs of the Funds, except as such
liability may arise from his or its own bad faith, willful misfeasance, gross
negligence or reckless disregard of his or her duties. It also provides that all
third parties shall look solely to the property of the International Funds or
the property of the appropriate International Fund for satisfaction of claims
arising in connection with the affairs of an International Fund. With the
exceptions stated, the Agreement and Declaration of Trust permits the Trustees
to provide for the indemnification of Trustees, officers, employees or agents of
the International Funds against all liability in connection with the affairs of
the International Funds.

     All shares of the International Funds when duly issued will be fully paid
and non-assessable. The Trustees are authorized to re-classify and issue any
unissued shares to any number of additional series without shareholder approval.
Accordingly, the Trustees in the future, for reasons such as the desire to
establish one or more additional International Funds with different investment

objectives, policies, risk considerations or restrictions, may create additional
series or classes of shares. Any issuance of shares of such additional series
would be governed by the 1940 Act and the laws of the State of Delaware.

Counsel and Independent Auditors

     Skadden, Arps, Slate, Meagher & Flom LLP, 919 Third Avenue, New York, New
York 10022, serves as legal counsel for the International Funds.

     Ernst & Young LLP, 787 Seventh Avenue, New York, New York 10019, has been
appointed as independent auditors for the Opportunity Funds.

Funds with the SEC under the Securities Act of 1933. Copies of the Registration

                                    APPENDIX

     The following is a description of the ratings given by Moody's and S&P to
corporate bonds.

                           RATINGS OF CORPORATE BONDS

S&P:

     Debt rated AAA has the highest rating assigned by S&P. Capacity to pay
interest and repay principal is extremely strong. Debt rated AA has a very
strong capacity to pay interest and repay principal and differs from the highest
rated issues only in small degree. Debt rated A has a strong capacity to pay
interest and repay principal although it is somewhat more susceptible to the
adverse effects of changes in circumstances and economic conditions than debt in
higher rated categories. Debt rated BBB is regarded as having adequate capacity
to pay interest and repay principal. Whereas it normally exhibits adequate
protection parameters, adverse economic conditions or changing circumstances are
more likely to lead to a weakened capacity to pay interest and repay principal
for debt in this category than in higher rated categories.

     Debt rated BB, B, CCC, CC and C is regarded as having predominantly
speculative characteristics with respect to capacity to pay interest and repay
principal. BB indicates the least degree of speculation and C the highest. While
such debt will likely have some quality and protective characteristics, these
are outweighed by large uncertainties or major exposures to adverse conditions.

     Debt rated BB has less near-term vulnerability to default than other
speculative issues. However, it faces major ongoing uncertainties or exposure to
adverse business, financial, or economic conditions which could lead to
inadequate capacity to meet timely interest and principal payments. The BB
rating category is also used for debt subordinated to senior debt that is
assigned an actual or implied BBB - rating. Debt rated B has a greater
vulnerability to default but currently has the capacity to meet interest
payments and principal repayments. Adverse business, financial or economic
conditions will likely impair capacity or willingness to pay interest and repay
principal. The B rating category is also used for debt subordinated to senior
debt that is assigned an actual or implied BB or BB - rating.

     Debt rated CCC has a currently identifiable vulnerability to default, and
is dependent upon favorable business, financial, and economic conditions to meet
timely payment of interest and repayment of principal. In the event of adverse
business, financial, or economic conditions, it is not likely to have the
capacity to pay interest and repay principal. The CCC rating category is also
used for debt subordinated to senior debt that is assigned an actual or implied
B or B - rating. The rating CC typically is applied to debt subordinated to
senior debt that is assigned an actual or implied CCC rating. The rating C
typically is applied to debt subordinated to senior debt which is assigned an
actual or implied CCC - debt rating. The C rating may be used to cover a
situation where a bankruptcy petition has been filed, but debt service payments
are continued. 




                                       35
<PAGE>


The rating C1 is reserved for income bonds on which no interest is being paid.
Debt rated D is in payment default. The D rating category is used when interest
payments or principal payments are not made on the date due even if the
applicable grace period had not expired, unless S&P believes that such payments
will be made during such grace period. The D rating also will be used upon the
filing of a bankruptcy petition if debt service payments are jeopardized.

Moody's:

     Bonds rated Aaa are judged to be of the best quality. They carry the
smallest degree of investment risk and are generally referred to as "gilt edge."
Interest payments are protected by a large or by an exceptionally stable margin
and principal is secure. While the various protective elements are likely to
change, such changes as can be visualized are most unlikely to impair the
fundamentally strong position of such issues. Bonds which are rated Aa are
judged to be of high quality by all standards. Together with the Aaa group they
comprise what are generally known as high grade bonds. They are rated lower than
the best bonds A-1 because margins of protection may not be as large as in Aaa
securities or fluctuation of protective elements may be of greater amplitude or
there may be other elements present which make the long term risks appear
somewhat larger than in Aaa securities. Bonds which are rated A possess many
favorable investment attributes and are to be considered as upper medium grade
obligations. Factors giving security to principal and interest are considered
adequate but elements may be present which suggest a susceptibility to
impairment sometime in the future.

     Bonds rated Baa are considered as medium grade obligations, i.e., they are
neither highly protected nor poorly secured. Interest payments and principal
security appear adequate for the present but certain protective elements may be
lacking or may be characteristically unreliable over any great length of time.
Such bonds lack outstanding investment characteristics and in fact have
speculative characteristics as well. Bonds which are rated Ba are judged to have
speculative elements; their future cannot be considered as well assured. Often
the protection of interest and principal payments may be very moderate and
thereby not well safeguarded during both good and bad times over the future.
Uncertainty of position characterizes bonds in this class. Bonds which are rated
B generally lack characteristics of the desirable investment. Assurance of
interest and principal payments or of maintenance of other terms of the contract
over any long period of time may be small.

     Bonds rated Caa are of poor standing. Such issues may be in default or
there may be present elements of danger with respect to principal or interest.
Bonds which are rated Ca represent obligations which are speculative in a high
degree. Such issues are often in default or have other marked shortcomings.
Bonds which are rated C are the lowest rated class of bonds and issues so rated
can be regarded as having extremely poor prospects of ever attaining any real
investment standing.

INDEMNIFICATION

     Registrant's Agreement and Declaration of Trust provides that the Trust
(for the appropriate Money or Equity Fund) shall indemnify each person who is or
has been a trustee or officer of the Trust (including persons who serve, or have
served, at the Trust's request as directors, officers or trustees of another
organization in which the Trust has any interest as a shareholder, creditor or
otherwise) against all liabilities, including but not limited to amounts paid in
satisfaction of judgments, in compromise or as fines and penalties, and
expenses, including reasonable accountants and counsel fees, incurred in
connection with the defense or disposition of any action, suit or proceeding,
whether civil or criminal, before any court or administrative or legislative
body, in which such person may be or may have been threatened, while in office
or thereafter, by reason of being or having been such a person, except with
respect to any matter as to which it has been determined that such person (i)

did not act in good faith in the reasonable belief that such person's action was
in the best interests of the Trust or (ii) had acted with willful misfeasance,
bad faith, gross negligence or reckless disregard of the duties involved in the
conduct of such person's office.

     The Investment Advisory Agreements between Registrant and DLJ Investment
Management Corp. (for the Money Funds) and Wood, Struthers & Winthrop Management
Corp. (for the Equity Funds) (together, the "Advisors") and the Investment
Sub-Advisory Agreement among the Registrant, AXA Asset Management Partenaires
(the "Sub-Advisor") and Wood, Struthers & Winthrop Management Corp. (the
"Sub-Advisory Agreement") provides that Advisors will not be liable thereunder
for any mistake of judgment or in any event whatsoever except for lack of good
faith and that nothing therein shall be deemed to protect Advisors and
Sub-Advisor against any liability to Registrant or its security holders to which
they would otherwise be subject by reason of willful misfeasance, bad faith or
gross negligence in the performance of its duties thereunder, or by reason of
reckless disregard of its duties and obligations thereunder.



<PAGE>


     The Sub-Advisory Agreement provides that the Sub-Advisor will indemnify
Wood, Struthers & Winthrop Management Corp. and its directors, officers,
employees, agents, associates and controlling persons while acting in any
capacity set forth in the Sub-Advisory Agreement except such activities arising
by reason of willful misfeasance, bad faith, gross negligence or reckless
disregard to the duties involved in the conduct of such person's office.

     The Sub-Advisory Agreement provides that Wood, Struthers & Winthrop
Management Corp. will indemnify the Sub-Advisor and its directors, officers,
employees, agents, associates and controlling persons while acting in any
capacity set forth in the Sub-Advisory Agreement except such activities arising
by reason of willful misfeasance, bad faith, gross negligence or reckless
disregard to the duties involved in the conduct of such person's office.

     The Distribution Agreement between the Registrant and Donaldson, Lufkin &
Jenrette Securities Corporation provides that Registrant will indemnify, defend
and hold Donaldson, Lufkin & Jenrette Securities Corporation, and any other
person who controls it within the meaning of Section 15 of the Investment
Company Act of 1940, free and harmless from and against any and all claims,
demands, liabilities and expenses which Donaldson, Lufkin & Jenrette Securities
Corporation or any controlling person may incur arising out of or based upon any
alleged untrue statement of a material fact contained in Registrant's
Registration Statement, Prospectus or Statement of Additional Information or
arising out of, or based upon any alleged omission to state a material fact
required to be stated in any one of the foregoing or necessary to make the
statements in any one of the foregoing not misleading.

     The foregoing summaries are qualified by the entire text of Registrant's
Agreement and Declaration of Trust, the Investment Advisory Agreements between
Registrant and the Advisors and the Distribution Agreement between Registration
and Donaldson, Lufkin & Jenrette Securities Corporation. The Registrant's

Investment Advisory Agreements are attached hereto as exhibit 6 or have been
previously filed, and the Agreement and Declaration of Trust and the
Distribution Agreement have been previously filed in response to Item 24.

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

     The Equitable Life Assurance Society of the United States (the parent of
Advisors' parent) carries for itself and its subsidiaries Directors and Officers
Liability Insurance. Coverage

covered up to the limits specified for any claim against them for acts committed
in their capacities as members of the Board.

                          JOINT INSURED BOND AGREEMENT

     AGREEMENT made this 23rd day of January 1997 between Winthrop Focus Funds,
a Massachusetts business trust, and Winthrop Opportunity Funds, a Delaware
business trust (each an "Insured" and together, the "Insureds") pursuant to Rule
17g-1 (f) under the Investment Company Act of 1940 (the "1940 Act") relating to
the Insureds' joint insured bond (the "Bond").

     The undersigned hereby agree that in the event recovery is received under
the Bond as a result of a loss sustained by each of the Insureds, each Insured
shall receive an equitable and proportionate share of the recovery, and in all
such events such share of the recovery shall be an amount that is at least equal
to the amount which it would have received had it maintained a single insured
bond with the minimum coverage required by Rule 17g-1(d) under the 1940 Act.

1    While the International Funds commenced operations on September 8, 1995,
     assets were not available for investment until September 13, 1995.

*    Each Fund's average annual return figures assume all dividends and
     distributions by such Fund over the relevant time period were reinvested
     and the maximum sales charge, if any, was imposed. It was then assumed that
     at the end of these periods, the entire amount was redeemed and the
     appropriate deferred sales load, if applicable, was deducted. The average
     annual return was then calculated by calculating the rate required for the
     initial payment to grow to the amount which would have been received upon
     redemption (i.e., the average annual rate of return).
